Safety Instructions Warnings and NotesEN 4 L032L AA2
2 Safety Instructions Warnings and Notes
Index of this chapter21 Safety Instructions22 Maintenance Instructions23 Warnings24 Notes
21 Safety Instructions
Safety regulations require that during a repairbull Connect the set to the Mains (AC Power) via an isolation
transformer (gt 800 VA)bull Replace safety components indicated by the symbol
only by components identical to the original ones Any other component substitution (other than original type) may increase risk of fire or electrical shock hazard
bull Wear safety goggles when you replace the CRT Safety regulations require that after a repair the set must be returned in its original condition Pay in particular attention to the following points bull General repair instruction as a strict precaution we advise
you to re-solder the solder connections through which the horizontal deflection current is flowing In particular this is valid for the1 Pins of the line output transformer (LOT)2 Fly-back capacitor(s)3 S-correction capacitor(s)4 Line output transistor5 Pins of the connector with wires to the deflection coil6 Other components through which the deflection current
flows
Note This re-soldering is advised to prevent bad connections due to metal fatigue in solder connections and is therefore only necessary for television sets more than two years oldbull Route the wire trees and EHT cable correctly and secure
them with the mounted cable clampsbull Check the insulation of the Mains (AC Power) lead for
external damage bull Check the strain relief of the mains (AC Power) cord for
proper function to prevent the cord from touching the CRT hot components or heat sinks
bull Check the electrical DC resistance between the Mains (AC Power) plug and the secondary side (only for sets which have a Mains (AC Power) isolated power supply) 1 Unplug the Mains (AC Power) cord and connect a wire
between the two pins of the Mains (AC Power) plug 2 Set the Mains (AC Power) switch to the on position
(keep the Mains (AC Power) cord unplugged) 3 Measure the resistance value between the pins of the
Mains (AC Power) plug and the metal shielding of the tuner or the aerial connection on the set The reading should be between 45 Mohm and 12 Mohm
4 Switch off the set and remove the wire between the two pins of the Mains (AC Power) plug
bull Check the cabinet for defects to avoid touching of any inner parts by the customer
22 Maintenance Instructions
We recommend a maintenance inspection carried out by qualified service personnel The interval depends on the usage conditionsbull When a customer uses the set under normal
circumstances for example in a living room the recommended interval is three to five years
bull When a customer uses the set in an environment with higher dust grease or moisture levels for example in a kitchen the recommended interval is one year
bull The maintenance inspection includes the following actions
1 Perform the ldquogeneral repair instructionrdquo noted above2 Clean the power supply and deflection circuitry on the
chassis3 Clean the picture tube panel and the neck of the picture
tube
23 Warnings
bull In order to prevent damage to ICs and transistors avoid all high voltage flashovers In order to prevent damage to the picture tube use the method shown in figure ldquoDischarge picture tuberdquo to discharge the picture tube Use a high voltage probe and a multi-meter (position VDC) Discharge until the meter reading is 0 V (after approx 30 s)
Figure 2-1 Discharge picture tube
bull All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD ) Careless handling during repair can reduce life drastically Make sure that during repair you are connected with the same potential as the mass of the set by a wristband with resistance Keep components and tools also at this same potential Available ESD protection equipment ndash Complete kit ESD3 (small tablemat wristband
connection box extension cable and earth cable) 4822 310 10671
ndash Wristband tester 4822 344 13999 bull Be careful during measurements in the high voltage
section bull Never replace modules or other components while the unit
is switched on bull When you align the set use plastic rather than metal tools
This will prevent any short circuits and the danger of a circuit becoming unstable
24 Notes
241 General
bull Measure the voltages and waveforms with regard to the chassis (= tuner) ground () or hot ground () depending on the tested area of circuitry The voltages and waveforms shown in the diagrams are indicative Measure them in the Service Default Mode (see chapter 5) with a colour bar signal and stereo sound (L 3 kHz R 1 kHz unless stated otherwise) and picture carrier at 47525 MHz for PAL or 6125 MHz for NTSC (channel 3)
bull Where necessary measure the waveforms and voltages with () and without () aerial signal Measure the voltages in the power supply section both in normal operation () and in stand-by () These values are indicated by means of the appropriate symbols
bull The semiconductors indicated in the circuit diagram and in the parts lists are interchangeable per position with the
V
E_06532_007eps250304
Directions for Use EN 5L032L AA 3
semiconductors in the unit irrespective of the type indication on these semiconductors
242 Schematic Notes
bull All resistor values are in ohms and the value multiplier is often used to indicate the decimal point location (eg 2K2 indicates 22 kohm)
bull Resistor values with no multiplier may be indicated with either an E or an R (eg 220E or 220R indicates 220 ohm)
bull All capacitor values are given in micro-farads (micro= x10-6) nano-farads (n= x10-9) or pico-farads (p= x10-12)
bull Capacitor values may also use the value multiplier as the decimal point indication (eg 2p2 indicates 22 pF)
bull An asterisk () indicates component usage varies Refer to the diversity tables for the correct values
bull The correct component values are listed in the Spare Parts List Therefore always check this list when there is any doubt
243 Lead Free Solder
Philips CE is going to produce lead-free sets (PBF) from 112005 onwards
Figure 2-2 Lead-free logo
This sign normally has a diameter of 6 mm but if there is less space on a board also 3 mm is possible Regardless of this logo (is not always present) one must treat all sets from this date onwards according to the following rules
Due to lead-free technology some rules have to be respected by the workshop during a repairbull Use only lead-free soldering tin Philips SAC305 with order
code 0622 149 00106 If lead-free solder paste is required please contact the manufacturer of your soldering equipment In general use of solder paste within workshops should be avoided because paste is not easy to store and to handle
bull Use only adequate solder tools applicable for lead-free soldering tin The solder tool must be able
ndash To reach at least a solder-tip temperature of 400degCndash To stabilise the adjusted temperature at the solder-tipndash To exchange solder-tips for different applications
bull Adjust your solder tool so that a temperature around 360degC - 380degC is reached and stabilised at the solder joint Heating time of the solder-joint should not exceed ~ 4 sec Avoid temperatures above 400degC otherwise wear-out of tips will rise drastically and flux-fluid will be destroyed To avoid wear-out of tips switch ldquooffrdquo unused equipment or reduce heat
bull Mix of lead-free soldering tinparts with leaded soldering tinparts is possible but PHILIPS recommends strongly to avoid mixed regimes If not to avoid clean carefully the solder-joint from old tin and re-solder with new tin
bull Use only original spare-parts listed in the Service-Manuals Not listed standard material (commodities) has to be purchased at external companies
bull For sets produced before 112005 containing leaded soldering tin and components all needed spare parts will be available till the end of the service period For the repair of such sets nothing changes
In case of doubt whether the board is lead-free or not (or with mixed technologies) you can use the following methodbull Always use the highest temperature to solder when using
SAC305 (see also instructions below)bull De-solder thoroughly (clean solder joints to avoid mix of
two alloys)Caution For BGA-ICs you must use the correct temperature-profile which is coupled to the 12NC For an overview of these profiles visit the website wwwatyourservicecephilipscom (needs subscription but is not available for all regions)You will find this and more technical information within the Magazine chapter Workshop informationFor additional questions please contact your local repair help desk
244 Practical Service Precautions
bull It makes sense to avoid exposure to electrical shock While some sources are expected to have a possible dangerous impact others of quite high potential are of limited current and are sometimes held in less regard
bull Always respect voltages While some may not be dangerous in themselves they can cause unexpected reactions that are best avoided Before reaching into a powered TV set it is best to test the high voltage insulation It is easy to do and is a good service precaution

54 ComPair
541 Introduction
ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products ComPair is a further development on the European DST (service remote control) which allows faster and more accurate diagnostics ComPair has three big advantagesbull ComPair helps you to quickly get an understanding on how
to repair the chassis in a short time by guiding you systematically through the repair procedures
bull ComPair allows very detailed diagnostics (on I2C level) and is therefore capable of accurately indicating problem areas You do not have to know anything about I2C commands yourself because ComPair takes care of this
bull ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available When ComPair is installed together with the SearchMan electronic manual of the defective chassis schematics and PWBs are only a mouse click away
542 Specifications
ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product The ComPair interface box is connected to the PC via a serial or RS232 cable In this chassis the ComPair interface box and the TV communicate via a bi-directional service cable via the service
Service Modes Error Codes and Fault Finding EN 9L032L AA 5
connector (located on the Main panel (see figure Top view Mono Carrier in chapter 8 Alignments) The ComPair faultfinding program is able to determine the problem of the defective television ComPair can gather diagnostic information in two waysbull Automatic (by communication with the television)
ComPair can automatically read out the contents of the entire error buffer Diagnosis is done on I2C level ComPair can access the I2C bus of the television ComPair can send and receive I2C commands to the micro controller of the television In this way it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set
bull Manually (by asking questions to you) Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extent When this is not the case ComPair will guide you through the faultfinding tree by asking you questions (eg Does the screen give a picture Click on the correct answer YES NO) and showing you examples (eg Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope) You can answer by clicking on a link (eg text or a waveform picture) that will bring you to the next step in the faultfinding process
By a combination of automatic diagnostics and an interactive question answer procedure ComPair will enable you to find most problems in a fast and effective way Besides fault finding ComPair provides some additional features likebull Up- or downloading of pre-setsbull Managing of pre-set listsbull Emulation of the Dealer Service Tool (DST)bull If both ComPair and SearchMan (Electronic Service
Manual) are installed all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink Example Measure the DC-voltage on capacitor C2568 (SchematicPanel) at the Mono-carrier ndash Click on the Panel hyperlink to automatically show the
PWB with a highlighted capacitor C2568 ndash Click on the Schematic hyperlink to automatically
show the position of the highlighted capacitor
543 How to Connect ComPair
1 First install the ComPair Browser software (see the Quick Reference Card for installation instructions)
2 Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with ldquoPCrdquo) of the ComPair interface
3 Connect the AC power adapter to the supply connector (marked with ldquoPOWER 9V DCrdquo) on the ComPair interface
4 Switch the ComPair interface OFF5 Switch the television set OFF (remove the AC power)6 Connect the ComPair interface cable between the
connector on the rear side of the ComPair interface (marked with ldquoI2Crdquo) and the ComPair connector on the mono carrier (see figure Top view Mono Carrier in chapter 8 Alignments)
7 Plug the AC power adapter in the AC power outlet and switch on the interface The green and red LEDs light up together The red LED extinguishes after approx 1 second while the green LED remains lit

545 Error Buffer
The error code buffer contains all detected errors since the last time the buffer was erased The buffer is written from left to right When an error occurs that is not yet in the error code buffer it is written at the left side and all other errors shift one position to the right
546 How To Read the Error Buffer
You can read the error buffer in 3 waysbull On screen via the SDAM (only if you have a picture)
Examplesndash ERROR 0 0 0 0 0 No errors detectedndash ERROR 6 0 0 0 0 Error code 6 is the last and only
detected errorndash ERROR 9 6 0 0 0 Error code 6 was first detected and
error code 9 is the last detected (newest) errorbull Via the blinking LED procedure (when you have no
picture) See next paragraphbull Via ComPair
547 How to Clear the Error Buffer
The error code buffer is cleared in the following casesbull By activation of the CLEAR command in the SDAM menubull If the content of the error buffer has not changed for 50
hours it resets automatically
NoteWhen leaving SDAM by disconnecting the set from AC power the error buffer is not reset

55 Error Codes
In case of non-intermittent faults clear the error buffer before you begin the repair These to ensure that old error codes are no longer present If possible check the entire contents of the error buffer In some situations an error code is only the result of another error code and not the actual cause (eg a fault in the protection detection circuitry can also lead to a protection)
Table 5-3 Error Code Table
56 The Blinking LED Procedure
Via this procedure you can make the contents of the error buffer visible via the front LED This is especially useful when there is no picture When the SDAM is entered the LED will blink the contents of the error-buffer bull n short blinks (n = 1 - 14)bull When all the error-codes are displayed the sequence
finishes with a LED blink of 3 sbull The sequence starts again
Example of error buffer 12 9 6 0 0 After entering SDAM bull 12 short blinks followed by a pause of 3 sbull 9 short blinks followed by a pause of 3 sbull 6 short blinks followed by a pause of 3 sbull 1 long blink of 3 s to finish the sequencebull the sequence starts again
57 Protections
If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode Blinking of the red LED at a frequency of 3 Hz indicates the protection mode In some error cases the microprocessor does not put the set in the protection mode The error codes of the error buffer can be read via the service menu (SDAM) the blinking LED procedure or via ComPair To get a quick diagnosis the chassis has one service modes implementedbull The Service Default Alignment Mode (SDAM) Start-up of
the set in a predefined way and adjustment of the set via a menu and with the help of test patterns
58 Repair Tips
Below some failure symptoms are given followed by a repair tipbull Set is dead and makes hiccupping sound ldquoMain
Supplyrdquo is available Hiccupping stops when de-soldering L5563 meaning that problem is in the ldquoMain Supplyrdquo line No output voltages at LOT no horizontal deflection Reason line transistor 7421 is defective
bull Set is dead and makes no sound Check power supply IC 7520 Result voltage at pins 2 6 7 9 and 11 are about 180 V and pin 14 is 0 V The reason why the voltage on these pins is so high is because the output driver (pin 11) has an open load That is why MOSFET 7521 is not able to switch Reason feedback resistor 3523 is defective Caution be careful measuring on the gate of 7521 circuitry is very high ohmic and can easily be damaged
bull Set is in hiccup mode and shuts down after 8 s Blinking LED (set in SDM mode) indicates error 5 As it is unlikely that the ldquoPORrdquo and ldquo+8V protectionrdquo happen at the same time measure the ldquo+8Vrdquo If this voltage is missing check transistor 7491 and 7496
bull Set is non-stop in hiccup mode Set is in over current mode check the secondary sensing (opto coupler 7515) and the ldquoMain Supplyrdquo voltage Signal ldquoStdby_conrdquo must be logic low under normal operation conditions and goes to high (33 V) under standby and fault conditions
bull Set turns on but without picture and sound The screen shows snow but OSD and other menus are okay Blinking LED procedure indicates error 11 so problem is expected in the tuner (pos 1000) Check presence of supply voltages As ldquoVlotaux+5Vrdquo at pin 5 and 7 are okay ldquoVT_supplyrdquo at pin 9 is missing Conclusion resistor 3449 and 3450 are defective

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds

How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

bull For a good understanding of the following circuit descriptions please use the block diagram in chapter 6 andor the electrical diagrams in chapter 7 Where necessary you will find a separate drawing for clarification
91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC

971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)
I2C protectionTo check whether all I2C ICs are functioning

Safety Instructions Warnings and NotesEN 4 L032L AA2
2 Safety Instructions Warnings and Notes
Index of this chapter21 Safety Instructions22 Maintenance Instructions23 Warnings24 Notes
21 Safety Instructions
Safety regulations require that during a repairbull Connect the set to the Mains (AC Power) via an isolation
transformer (gt 800 VA)bull Replace safety components indicated by the symbol
only by components identical to the original ones Any other component substitution (other than original type) may increase risk of fire or electrical shock hazard
bull Wear safety goggles when you replace the CRT Safety regulations require that after a repair the set must be returned in its original condition Pay in particular attention to the following points bull General repair instruction as a strict precaution we advise
you to re-solder the solder connections through which the horizontal deflection current is flowing In particular this is valid for the1 Pins of the line output transformer (LOT)2 Fly-back capacitor(s)3 S-correction capacitor(s)4 Line output transistor5 Pins of the connector with wires to the deflection coil6 Other components through which the deflection current
flows
Note This re-soldering is advised to prevent bad connections due to metal fatigue in solder connections and is therefore only necessary for television sets more than two years oldbull Route the wire trees and EHT cable correctly and secure
them with the mounted cable clampsbull Check the insulation of the Mains (AC Power) lead for
external damage bull Check the strain relief of the mains (AC Power) cord for
proper function to prevent the cord from touching the CRT hot components or heat sinks
bull Check the electrical DC resistance between the Mains (AC Power) plug and the secondary side (only for sets which have a Mains (AC Power) isolated power supply) 1 Unplug the Mains (AC Power) cord and connect a wire
between the two pins of the Mains (AC Power) plug 2 Set the Mains (AC Power) switch to the on position
(keep the Mains (AC Power) cord unplugged) 3 Measure the resistance value between the pins of the
Mains (AC Power) plug and the metal shielding of the tuner or the aerial connection on the set The reading should be between 45 Mohm and 12 Mohm
4 Switch off the set and remove the wire between the two pins of the Mains (AC Power) plug
bull Check the cabinet for defects to avoid touching of any inner parts by the customer
22 Maintenance Instructions
We recommend a maintenance inspection carried out by qualified service personnel The interval depends on the usage conditionsbull When a customer uses the set under normal
circumstances for example in a living room the recommended interval is three to five years
bull When a customer uses the set in an environment with higher dust grease or moisture levels for example in a kitchen the recommended interval is one year
bull The maintenance inspection includes the following actions
1 Perform the ldquogeneral repair instructionrdquo noted above2 Clean the power supply and deflection circuitry on the
chassis3 Clean the picture tube panel and the neck of the picture
tube
23 Warnings
bull In order to prevent damage to ICs and transistors avoid all high voltage flashovers In order to prevent damage to the picture tube use the method shown in figure ldquoDischarge picture tuberdquo to discharge the picture tube Use a high voltage probe and a multi-meter (position VDC) Discharge until the meter reading is 0 V (after approx 30 s)
Figure 2-1 Discharge picture tube
bull All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD ) Careless handling during repair can reduce life drastically Make sure that during repair you are connected with the same potential as the mass of the set by a wristband with resistance Keep components and tools also at this same potential Available ESD protection equipment ndash Complete kit ESD3 (small tablemat wristband
connection box extension cable and earth cable) 4822 310 10671
ndash Wristband tester 4822 344 13999 bull Be careful during measurements in the high voltage
section bull Never replace modules or other components while the unit
is switched on bull When you align the set use plastic rather than metal tools
This will prevent any short circuits and the danger of a circuit becoming unstable
24 Notes
241 General
bull Measure the voltages and waveforms with regard to the chassis (= tuner) ground () or hot ground () depending on the tested area of circuitry The voltages and waveforms shown in the diagrams are indicative Measure them in the Service Default Mode (see chapter 5) with a colour bar signal and stereo sound (L 3 kHz R 1 kHz unless stated otherwise) and picture carrier at 47525 MHz for PAL or 6125 MHz for NTSC (channel 3)
bull Where necessary measure the waveforms and voltages with () and without () aerial signal Measure the voltages in the power supply section both in normal operation () and in stand-by () These values are indicated by means of the appropriate symbols
bull The semiconductors indicated in the circuit diagram and in the parts lists are interchangeable per position with the
V
E_06532_007eps250304
Directions for Use EN 5L032L AA 3
semiconductors in the unit irrespective of the type indication on these semiconductors
242 Schematic Notes
bull All resistor values are in ohms and the value multiplier is often used to indicate the decimal point location (eg 2K2 indicates 22 kohm)
bull Resistor values with no multiplier may be indicated with either an E or an R (eg 220E or 220R indicates 220 ohm)
bull All capacitor values are given in micro-farads (micro= x10-6) nano-farads (n= x10-9) or pico-farads (p= x10-12)
bull Capacitor values may also use the value multiplier as the decimal point indication (eg 2p2 indicates 22 pF)
bull An asterisk () indicates component usage varies Refer to the diversity tables for the correct values
bull The correct component values are listed in the Spare Parts List Therefore always check this list when there is any doubt
243 Lead Free Solder
Philips CE is going to produce lead-free sets (PBF) from 112005 onwards
Figure 2-2 Lead-free logo
This sign normally has a diameter of 6 mm but if there is less space on a board also 3 mm is possible Regardless of this logo (is not always present) one must treat all sets from this date onwards according to the following rules
Due to lead-free technology some rules have to be respected by the workshop during a repairbull Use only lead-free soldering tin Philips SAC305 with order
code 0622 149 00106 If lead-free solder paste is required please contact the manufacturer of your soldering equipment In general use of solder paste within workshops should be avoided because paste is not easy to store and to handle
bull Use only adequate solder tools applicable for lead-free soldering tin The solder tool must be able
ndash To reach at least a solder-tip temperature of 400degCndash To stabilise the adjusted temperature at the solder-tipndash To exchange solder-tips for different applications
bull Adjust your solder tool so that a temperature around 360degC - 380degC is reached and stabilised at the solder joint Heating time of the solder-joint should not exceed ~ 4 sec Avoid temperatures above 400degC otherwise wear-out of tips will rise drastically and flux-fluid will be destroyed To avoid wear-out of tips switch ldquooffrdquo unused equipment or reduce heat
bull Mix of lead-free soldering tinparts with leaded soldering tinparts is possible but PHILIPS recommends strongly to avoid mixed regimes If not to avoid clean carefully the solder-joint from old tin and re-solder with new tin
bull Use only original spare-parts listed in the Service-Manuals Not listed standard material (commodities) has to be purchased at external companies
bull For sets produced before 112005 containing leaded soldering tin and components all needed spare parts will be available till the end of the service period For the repair of such sets nothing changes
In case of doubt whether the board is lead-free or not (or with mixed technologies) you can use the following methodbull Always use the highest temperature to solder when using
SAC305 (see also instructions below)bull De-solder thoroughly (clean solder joints to avoid mix of
two alloys)Caution For BGA-ICs you must use the correct temperature-profile which is coupled to the 12NC For an overview of these profiles visit the website wwwatyourservicecephilipscom (needs subscription but is not available for all regions)You will find this and more technical information within the Magazine chapter Workshop informationFor additional questions please contact your local repair help desk
244 Practical Service Precautions
bull It makes sense to avoid exposure to electrical shock While some sources are expected to have a possible dangerous impact others of quite high potential are of limited current and are sometimes held in less regard
bull Always respect voltages While some may not be dangerous in themselves they can cause unexpected reactions that are best avoided Before reaching into a powered TV set it is best to test the high voltage insulation It is easy to do and is a good service precaution

54 ComPair
541 Introduction
ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products ComPair is a further development on the European DST (service remote control) which allows faster and more accurate diagnostics ComPair has three big advantagesbull ComPair helps you to quickly get an understanding on how
to repair the chassis in a short time by guiding you systematically through the repair procedures
bull ComPair allows very detailed diagnostics (on I2C level) and is therefore capable of accurately indicating problem areas You do not have to know anything about I2C commands yourself because ComPair takes care of this
bull ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available When ComPair is installed together with the SearchMan electronic manual of the defective chassis schematics and PWBs are only a mouse click away
542 Specifications
ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product The ComPair interface box is connected to the PC via a serial or RS232 cable In this chassis the ComPair interface box and the TV communicate via a bi-directional service cable via the service
Service Modes Error Codes and Fault Finding EN 9L032L AA 5
connector (located on the Main panel (see figure Top view Mono Carrier in chapter 8 Alignments) The ComPair faultfinding program is able to determine the problem of the defective television ComPair can gather diagnostic information in two waysbull Automatic (by communication with the television)
ComPair can automatically read out the contents of the entire error buffer Diagnosis is done on I2C level ComPair can access the I2C bus of the television ComPair can send and receive I2C commands to the micro controller of the television In this way it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set
bull Manually (by asking questions to you) Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extent When this is not the case ComPair will guide you through the faultfinding tree by asking you questions (eg Does the screen give a picture Click on the correct answer YES NO) and showing you examples (eg Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope) You can answer by clicking on a link (eg text or a waveform picture) that will bring you to the next step in the faultfinding process
By a combination of automatic diagnostics and an interactive question answer procedure ComPair will enable you to find most problems in a fast and effective way Besides fault finding ComPair provides some additional features likebull Up- or downloading of pre-setsbull Managing of pre-set listsbull Emulation of the Dealer Service Tool (DST)bull If both ComPair and SearchMan (Electronic Service
Manual) are installed all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink Example Measure the DC-voltage on capacitor C2568 (SchematicPanel) at the Mono-carrier ndash Click on the Panel hyperlink to automatically show the
PWB with a highlighted capacitor C2568 ndash Click on the Schematic hyperlink to automatically
show the position of the highlighted capacitor
543 How to Connect ComPair
1 First install the ComPair Browser software (see the Quick Reference Card for installation instructions)
2 Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with ldquoPCrdquo) of the ComPair interface
3 Connect the AC power adapter to the supply connector (marked with ldquoPOWER 9V DCrdquo) on the ComPair interface
4 Switch the ComPair interface OFF5 Switch the television set OFF (remove the AC power)6 Connect the ComPair interface cable between the
connector on the rear side of the ComPair interface (marked with ldquoI2Crdquo) and the ComPair connector on the mono carrier (see figure Top view Mono Carrier in chapter 8 Alignments)
7 Plug the AC power adapter in the AC power outlet and switch on the interface The green and red LEDs light up together The red LED extinguishes after approx 1 second while the green LED remains lit

545 Error Buffer
The error code buffer contains all detected errors since the last time the buffer was erased The buffer is written from left to right When an error occurs that is not yet in the error code buffer it is written at the left side and all other errors shift one position to the right
546 How To Read the Error Buffer
You can read the error buffer in 3 waysbull On screen via the SDAM (only if you have a picture)
Examplesndash ERROR 0 0 0 0 0 No errors detectedndash ERROR 6 0 0 0 0 Error code 6 is the last and only
detected errorndash ERROR 9 6 0 0 0 Error code 6 was first detected and
error code 9 is the last detected (newest) errorbull Via the blinking LED procedure (when you have no
picture) See next paragraphbull Via ComPair
547 How to Clear the Error Buffer
The error code buffer is cleared in the following casesbull By activation of the CLEAR command in the SDAM menubull If the content of the error buffer has not changed for 50
hours it resets automatically
NoteWhen leaving SDAM by disconnecting the set from AC power the error buffer is not reset

Service Modes Error Codes and Fault FindingEN 10 L032L AA5
55 Error Codes
In case of non-intermittent faults clear the error buffer before you begin the repair These to ensure that old error codes are no longer present If possible check the entire contents of the error buffer In some situations an error code is only the result of another error code and not the actual cause (eg a fault in the protection detection circuitry can also lead to a protection)
Table 5-3 Error Code Table
56 The Blinking LED Procedure
Via this procedure you can make the contents of the error buffer visible via the front LED This is especially useful when there is no picture When the SDAM is entered the LED will blink the contents of the error-buffer bull n short blinks (n = 1 - 14)bull When all the error-codes are displayed the sequence
finishes with a LED blink of 3 sbull The sequence starts again
Example of error buffer 12 9 6 0 0 After entering SDAM bull 12 short blinks followed by a pause of 3 sbull 9 short blinks followed by a pause of 3 sbull 6 short blinks followed by a pause of 3 sbull 1 long blink of 3 s to finish the sequencebull the sequence starts again
57 Protections
If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode Blinking of the red LED at a frequency of 3 Hz indicates the protection mode In some error cases the microprocessor does not put the set in the protection mode The error codes of the error buffer can be read via the service menu (SDAM) the blinking LED procedure or via ComPair To get a quick diagnosis the chassis has one service modes implementedbull The Service Default Alignment Mode (SDAM) Start-up of
the set in a predefined way and adjustment of the set via a menu and with the help of test patterns
58 Repair Tips
Below some failure symptoms are given followed by a repair tipbull Set is dead and makes hiccupping sound ldquoMain
Supplyrdquo is available Hiccupping stops when de-soldering L5563 meaning that problem is in the ldquoMain Supplyrdquo line No output voltages at LOT no horizontal deflection Reason line transistor 7421 is defective
bull Set is dead and makes no sound Check power supply IC 7520 Result voltage at pins 2 6 7 9 and 11 are about 180 V and pin 14 is 0 V The reason why the voltage on these pins is so high is because the output driver (pin 11) has an open load That is why MOSFET 7521 is not able to switch Reason feedback resistor 3523 is defective Caution be careful measuring on the gate of 7521 circuitry is very high ohmic and can easily be damaged
bull Set is in hiccup mode and shuts down after 8 s Blinking LED (set in SDM mode) indicates error 5 As it is unlikely that the ldquoPORrdquo and ldquo+8V protectionrdquo happen at the same time measure the ldquo+8Vrdquo If this voltage is missing check transistor 7491 and 7496
bull Set is non-stop in hiccup mode Set is in over current mode check the secondary sensing (opto coupler 7515) and the ldquoMain Supplyrdquo voltage Signal ldquoStdby_conrdquo must be logic low under normal operation conditions and goes to high (33 V) under standby and fault conditions
bull Set turns on but without picture and sound The screen shows snow but OSD and other menus are okay Blinking LED procedure indicates error 11 so problem is expected in the tuner (pos 1000) Check presence of supply voltages As ldquoVlotaux+5Vrdquo at pin 5 and 7 are okay ldquoVT_supplyrdquo at pin 9 is missing Conclusion resistor 3449 and 3450 are defective

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)
How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

Safety Instructions Warnings and NotesEN 4 L032L AA2
2 Safety Instructions Warnings and Notes
Index of this chapter21 Safety Instructions22 Maintenance Instructions23 Warnings24 Notes
21 Safety Instructions
Safety regulations require that during a repairbull Connect the set to the Mains (AC Power) via an isolation
transformer (gt 800 VA)bull Replace safety components indicated by the symbol
only by components identical to the original ones Any other component substitution (other than original type) may increase risk of fire or electrical shock hazard
bull Wear safety goggles when you replace the CRT Safety regulations require that after a repair the set must be returned in its original condition Pay in particular attention to the following points bull General repair instruction as a strict precaution we advise
you to re-solder the solder connections through which the horizontal deflection current is flowing In particular this is valid for the1 Pins of the line output transformer (LOT)2 Fly-back capacitor(s)3 S-correction capacitor(s)4 Line output transistor5 Pins of the connector with wires to the deflection coil6 Other components through which the deflection current
flows
Note This re-soldering is advised to prevent bad connections due to metal fatigue in solder connections and is therefore only necessary for television sets more than two years oldbull Route the wire trees and EHT cable correctly and secure
them with the mounted cable clampsbull Check the insulation of the Mains (AC Power) lead for
external damage bull Check the strain relief of the mains (AC Power) cord for
proper function to prevent the cord from touching the CRT hot components or heat sinks
bull Check the electrical DC resistance between the Mains (AC Power) plug and the secondary side (only for sets which have a Mains (AC Power) isolated power supply) 1 Unplug the Mains (AC Power) cord and connect a wire
between the two pins of the Mains (AC Power) plug 2 Set the Mains (AC Power) switch to the on position
(keep the Mains (AC Power) cord unplugged) 3 Measure the resistance value between the pins of the
Mains (AC Power) plug and the metal shielding of the tuner or the aerial connection on the set The reading should be between 45 Mohm and 12 Mohm
4 Switch off the set and remove the wire between the two pins of the Mains (AC Power) plug
bull Check the cabinet for defects to avoid touching of any inner parts by the customer
22 Maintenance Instructions
We recommend a maintenance inspection carried out by qualified service personnel The interval depends on the usage conditionsbull When a customer uses the set under normal
circumstances for example in a living room the recommended interval is three to five years
bull When a customer uses the set in an environment with higher dust grease or moisture levels for example in a kitchen the recommended interval is one year
bull The maintenance inspection includes the following actions
1 Perform the ldquogeneral repair instructionrdquo noted above2 Clean the power supply and deflection circuitry on the
chassis3 Clean the picture tube panel and the neck of the picture
tube
23 Warnings
bull In order to prevent damage to ICs and transistors avoid all high voltage flashovers In order to prevent damage to the picture tube use the method shown in figure ldquoDischarge picture tuberdquo to discharge the picture tube Use a high voltage probe and a multi-meter (position VDC) Discharge until the meter reading is 0 V (after approx 30 s)
Figure 2-1 Discharge picture tube
bull All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD ) Careless handling during repair can reduce life drastically Make sure that during repair you are connected with the same potential as the mass of the set by a wristband with resistance Keep components and tools also at this same potential Available ESD protection equipment ndash Complete kit ESD3 (small tablemat wristband
connection box extension cable and earth cable) 4822 310 10671
ndash Wristband tester 4822 344 13999 bull Be careful during measurements in the high voltage
section bull Never replace modules or other components while the unit
is switched on bull When you align the set use plastic rather than metal tools
This will prevent any short circuits and the danger of a circuit becoming unstable
24 Notes
241 General
bull Measure the voltages and waveforms with regard to the chassis (= tuner) ground () or hot ground () depending on the tested area of circuitry The voltages and waveforms shown in the diagrams are indicative Measure them in the Service Default Mode (see chapter 5) with a colour bar signal and stereo sound (L 3 kHz R 1 kHz unless stated otherwise) and picture carrier at 47525 MHz for PAL or 6125 MHz for NTSC (channel 3)
bull Where necessary measure the waveforms and voltages with () and without () aerial signal Measure the voltages in the power supply section both in normal operation () and in stand-by () These values are indicated by means of the appropriate symbols
bull The semiconductors indicated in the circuit diagram and in the parts lists are interchangeable per position with the
V
E_06532_007eps250304
Directions for Use EN 5L032L AA 3
semiconductors in the unit irrespective of the type indication on these semiconductors
242 Schematic Notes
bull All resistor values are in ohms and the value multiplier is often used to indicate the decimal point location (eg 2K2 indicates 22 kohm)
bull Resistor values with no multiplier may be indicated with either an E or an R (eg 220E or 220R indicates 220 ohm)
bull All capacitor values are given in micro-farads (micro= x10-6) nano-farads (n= x10-9) or pico-farads (p= x10-12)
bull Capacitor values may also use the value multiplier as the decimal point indication (eg 2p2 indicates 22 pF)
bull An asterisk () indicates component usage varies Refer to the diversity tables for the correct values
bull The correct component values are listed in the Spare Parts List Therefore always check this list when there is any doubt
243 Lead Free Solder
Philips CE is going to produce lead-free sets (PBF) from 112005 onwards
Figure 2-2 Lead-free logo
This sign normally has a diameter of 6 mm but if there is less space on a board also 3 mm is possible Regardless of this logo (is not always present) one must treat all sets from this date onwards according to the following rules
Due to lead-free technology some rules have to be respected by the workshop during a repairbull Use only lead-free soldering tin Philips SAC305 with order
code 0622 149 00106 If lead-free solder paste is required please contact the manufacturer of your soldering equipment In general use of solder paste within workshops should be avoided because paste is not easy to store and to handle
bull Use only adequate solder tools applicable for lead-free soldering tin The solder tool must be able
ndash To reach at least a solder-tip temperature of 400degCndash To stabilise the adjusted temperature at the solder-tipndash To exchange solder-tips for different applications
bull Adjust your solder tool so that a temperature around 360degC - 380degC is reached and stabilised at the solder joint Heating time of the solder-joint should not exceed ~ 4 sec Avoid temperatures above 400degC otherwise wear-out of tips will rise drastically and flux-fluid will be destroyed To avoid wear-out of tips switch ldquooffrdquo unused equipment or reduce heat
bull Mix of lead-free soldering tinparts with leaded soldering tinparts is possible but PHILIPS recommends strongly to avoid mixed regimes If not to avoid clean carefully the solder-joint from old tin and re-solder with new tin
bull Use only original spare-parts listed in the Service-Manuals Not listed standard material (commodities) has to be purchased at external companies
bull For sets produced before 112005 containing leaded soldering tin and components all needed spare parts will be available till the end of the service period For the repair of such sets nothing changes
In case of doubt whether the board is lead-free or not (or with mixed technologies) you can use the following methodbull Always use the highest temperature to solder when using
SAC305 (see also instructions below)bull De-solder thoroughly (clean solder joints to avoid mix of
two alloys)Caution For BGA-ICs you must use the correct temperature-profile which is coupled to the 12NC For an overview of these profiles visit the website wwwatyourservicecephilipscom (needs subscription but is not available for all regions)You will find this and more technical information within the Magazine chapter Workshop informationFor additional questions please contact your local repair help desk
244 Practical Service Precautions
bull It makes sense to avoid exposure to electrical shock While some sources are expected to have a possible dangerous impact others of quite high potential are of limited current and are sometimes held in less regard
bull Always respect voltages While some may not be dangerous in themselves they can cause unexpected reactions that are best avoided Before reaching into a powered TV set it is best to test the high voltage insulation It is easy to do and is a good service precaution

54 ComPair
541 Introduction
ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products ComPair is a further development on the European DST (service remote control) which allows faster and more accurate diagnostics ComPair has three big advantagesbull ComPair helps you to quickly get an understanding on how
to repair the chassis in a short time by guiding you systematically through the repair procedures
bull ComPair allows very detailed diagnostics (on I2C level) and is therefore capable of accurately indicating problem areas You do not have to know anything about I2C commands yourself because ComPair takes care of this
bull ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available When ComPair is installed together with the SearchMan electronic manual of the defective chassis schematics and PWBs are only a mouse click away
542 Specifications
ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product The ComPair interface box is connected to the PC via a serial or RS232 cable In this chassis the ComPair interface box and the TV communicate via a bi-directional service cable via the service
Service Modes Error Codes and Fault Finding EN 9L032L AA 5
connector (located on the Main panel (see figure Top view Mono Carrier in chapter 8 Alignments) The ComPair faultfinding program is able to determine the problem of the defective television ComPair can gather diagnostic information in two waysbull Automatic (by communication with the television)
ComPair can automatically read out the contents of the entire error buffer Diagnosis is done on I2C level ComPair can access the I2C bus of the television ComPair can send and receive I2C commands to the micro controller of the television In this way it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set
bull Manually (by asking questions to you) Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extent When this is not the case ComPair will guide you through the faultfinding tree by asking you questions (eg Does the screen give a picture Click on the correct answer YES NO) and showing you examples (eg Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope) You can answer by clicking on a link (eg text or a waveform picture) that will bring you to the next step in the faultfinding process
By a combination of automatic diagnostics and an interactive question answer procedure ComPair will enable you to find most problems in a fast and effective way Besides fault finding ComPair provides some additional features likebull Up- or downloading of pre-setsbull Managing of pre-set listsbull Emulation of the Dealer Service Tool (DST)bull If both ComPair and SearchMan (Electronic Service
Manual) are installed all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink Example Measure the DC-voltage on capacitor C2568 (SchematicPanel) at the Mono-carrier ndash Click on the Panel hyperlink to automatically show the
PWB with a highlighted capacitor C2568 ndash Click on the Schematic hyperlink to automatically
show the position of the highlighted capacitor
543 How to Connect ComPair
1 First install the ComPair Browser software (see the Quick Reference Card for installation instructions)
2 Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with ldquoPCrdquo) of the ComPair interface
3 Connect the AC power adapter to the supply connector (marked with ldquoPOWER 9V DCrdquo) on the ComPair interface
4 Switch the ComPair interface OFF5 Switch the television set OFF (remove the AC power)6 Connect the ComPair interface cable between the
connector on the rear side of the ComPair interface (marked with ldquoI2Crdquo) and the ComPair connector on the mono carrier (see figure Top view Mono Carrier in chapter 8 Alignments)
7 Plug the AC power adapter in the AC power outlet and switch on the interface The green and red LEDs light up together The red LED extinguishes after approx 1 second while the green LED remains lit
8 Start the ComPair program and read the ldquointroductionrdquo chapter

545 Error Buffer
The error code buffer contains all detected errors since the last time the buffer was erased The buffer is written from left to right When an error occurs that is not yet in the error code buffer it is written at the left side and all other errors shift one position to the right
546 How To Read the Error Buffer
You can read the error buffer in 3 waysbull On screen via the SDAM (only if you have a picture)
Examplesndash ERROR 0 0 0 0 0 No errors detectedndash ERROR 6 0 0 0 0 Error code 6 is the last and only
detected errorndash ERROR 9 6 0 0 0 Error code 6 was first detected and
error code 9 is the last detected (newest) errorbull Via the blinking LED procedure (when you have no
picture) See next paragraphbull Via ComPair
547 How to Clear the Error Buffer
The error code buffer is cleared in the following casesbull By activation of the CLEAR command in the SDAM menubull If the content of the error buffer has not changed for 50
hours it resets automatically
NoteWhen leaving SDAM by disconnecting the set from AC power the error buffer is not reset

55 Error Codes
In case of non-intermittent faults clear the error buffer before you begin the repair These to ensure that old error codes are no longer present If possible check the entire contents of the error buffer In some situations an error code is only the result of another error code and not the actual cause (eg a fault in the protection detection circuitry can also lead to a protection)
Table 5-3 Error Code Table
56 The Blinking LED Procedure
Via this procedure you can make the contents of the error buffer visible via the front LED This is especially useful when there is no picture When the SDAM is entered the LED will blink the contents of the error-buffer bull n short blinks (n = 1 - 14)bull When all the error-codes are displayed the sequence
finishes with a LED blink of 3 sbull The sequence starts again
Example of error buffer 12 9 6 0 0 After entering SDAM bull 12 short blinks followed by a pause of 3 sbull 9 short blinks followed by a pause of 3 sbull 6 short blinks followed by a pause of 3 sbull 1 long blink of 3 s to finish the sequencebull the sequence starts again
57 Protections
If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode Blinking of the red LED at a frequency of 3 Hz indicates the protection mode In some error cases the microprocessor does not put the set in the protection mode The error codes of the error buffer can be read via the service menu (SDAM) the blinking LED procedure or via ComPair To get a quick diagnosis the chassis has one service modes implementedbull The Service Default Alignment Mode (SDAM) Start-up of
the set in a predefined way and adjustment of the set via a menu and with the help of test patterns
58 Repair Tips
Below some failure symptoms are given followed by a repair tipbull Set is dead and makes hiccupping sound ldquoMain
Supplyrdquo is available Hiccupping stops when de-soldering L5563 meaning that problem is in the ldquoMain Supplyrdquo line No output voltages at LOT no horizontal deflection Reason line transistor 7421 is defective
bull Set is dead and makes no sound Check power supply IC 7520 Result voltage at pins 2 6 7 9 and 11 are about 180 V and pin 14 is 0 V The reason why the voltage on these pins is so high is because the output driver (pin 11) has an open load That is why MOSFET 7521 is not able to switch Reason feedback resistor 3523 is defective Caution be careful measuring on the gate of 7521 circuitry is very high ohmic and can easily be damaged
bull Set is in hiccup mode and shuts down after 8 s Blinking LED (set in SDM mode) indicates error 5 As it is unlikely that the ldquoPORrdquo and ldquo+8V protectionrdquo happen at the same time measure the ldquo+8Vrdquo If this voltage is missing check transistor 7491 and 7496
bull Set is non-stop in hiccup mode Set is in over current mode check the secondary sensing (opto coupler 7515) and the ldquoMain Supplyrdquo voltage Signal ldquoStdby_conrdquo must be logic low under normal operation conditions and goes to high (33 V) under standby and fault conditions
bull Set turns on but without picture and sound The screen shows snow but OSD and other menus are okay Blinking LED procedure indicates error 11 so problem is expected in the tuner (pos 1000) Check presence of supply voltages As ldquoVlotaux+5Vrdquo at pin 5 and 7 are okay ldquoVT_supplyrdquo at pin 9 is missing Conclusion resistor 3449 and 3450 are defective

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)
How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

Safety Instructions Warnings and NotesEN 4 L032L AA2
2 Safety Instructions Warnings and Notes
Index of this chapter21 Safety Instructions22 Maintenance Instructions23 Warnings24 Notes
21 Safety Instructions
Safety regulations require that during a repairbull Connect the set to the Mains (AC Power) via an isolation
transformer (gt 800 VA)bull Replace safety components indicated by the symbol
only by components identical to the original ones Any other component substitution (other than original type) may increase risk of fire or electrical shock hazard
bull Wear safety goggles when you replace the CRT Safety regulations require that after a repair the set must be returned in its original condition Pay in particular attention to the following points bull General repair instruction as a strict precaution we advise
you to re-solder the solder connections through which the horizontal deflection current is flowing In particular this is valid for the1 Pins of the line output transformer (LOT)2 Fly-back capacitor(s)3 S-correction capacitor(s)4 Line output transistor5 Pins of the connector with wires to the deflection coil6 Other components through which the deflection current
flows
Note This re-soldering is advised to prevent bad connections due to metal fatigue in solder connections and is therefore only necessary for television sets more than two years oldbull Route the wire trees and EHT cable correctly and secure
them with the mounted cable clampsbull Check the insulation of the Mains (AC Power) lead for
external damage bull Check the strain relief of the mains (AC Power) cord for
proper function to prevent the cord from touching the CRT hot components or heat sinks
bull Check the electrical DC resistance between the Mains (AC Power) plug and the secondary side (only for sets which have a Mains (AC Power) isolated power supply) 1 Unplug the Mains (AC Power) cord and connect a wire
between the two pins of the Mains (AC Power) plug 2 Set the Mains (AC Power) switch to the on position
(keep the Mains (AC Power) cord unplugged) 3 Measure the resistance value between the pins of the
Mains (AC Power) plug and the metal shielding of the tuner or the aerial connection on the set The reading should be between 45 Mohm and 12 Mohm
4 Switch off the set and remove the wire between the two pins of the Mains (AC Power) plug
bull Check the cabinet for defects to avoid touching of any inner parts by the customer
22 Maintenance Instructions
We recommend a maintenance inspection carried out by qualified service personnel The interval depends on the usage conditionsbull When a customer uses the set under normal
circumstances for example in a living room the recommended interval is three to five years
bull When a customer uses the set in an environment with higher dust grease or moisture levels for example in a kitchen the recommended interval is one year
bull The maintenance inspection includes the following actions
1 Perform the ldquogeneral repair instructionrdquo noted above2 Clean the power supply and deflection circuitry on the
chassis3 Clean the picture tube panel and the neck of the picture
tube
23 Warnings
bull In order to prevent damage to ICs and transistors avoid all high voltage flashovers In order to prevent damage to the picture tube use the method shown in figure ldquoDischarge picture tuberdquo to discharge the picture tube Use a high voltage probe and a multi-meter (position VDC) Discharge until the meter reading is 0 V (after approx 30 s)
Figure 2-1 Discharge picture tube
bull All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD ) Careless handling during repair can reduce life drastically Make sure that during repair you are connected with the same potential as the mass of the set by a wristband with resistance Keep components and tools also at this same potential Available ESD protection equipment ndash Complete kit ESD3 (small tablemat wristband
connection box extension cable and earth cable) 4822 310 10671
ndash Wristband tester 4822 344 13999 bull Be careful during measurements in the high voltage
section bull Never replace modules or other components while the unit
is switched on bull When you align the set use plastic rather than metal tools
This will prevent any short circuits and the danger of a circuit becoming unstable
24 Notes
241 General
bull Measure the voltages and waveforms with regard to the chassis (= tuner) ground () or hot ground () depending on the tested area of circuitry The voltages and waveforms shown in the diagrams are indicative Measure them in the Service Default Mode (see chapter 5) with a colour bar signal and stereo sound (L 3 kHz R 1 kHz unless stated otherwise) and picture carrier at 47525 MHz for PAL or 6125 MHz for NTSC (channel 3)
bull Where necessary measure the waveforms and voltages with () and without () aerial signal Measure the voltages in the power supply section both in normal operation () and in stand-by () These values are indicated by means of the appropriate symbols
bull The semiconductors indicated in the circuit diagram and in the parts lists are interchangeable per position with the
V
E_06532_007eps250304
Directions for Use EN 5L032L AA 3
semiconductors in the unit irrespective of the type indication on these semiconductors
242 Schematic Notes
bull All resistor values are in ohms and the value multiplier is often used to indicate the decimal point location (eg 2K2 indicates 22 kohm)
bull Resistor values with no multiplier may be indicated with either an E or an R (eg 220E or 220R indicates 220 ohm)
bull All capacitor values are given in micro-farads (micro= x10-6) nano-farads (n= x10-9) or pico-farads (p= x10-12)
bull Capacitor values may also use the value multiplier as the decimal point indication (eg 2p2 indicates 22 pF)
bull An asterisk () indicates component usage varies Refer to the diversity tables for the correct values
bull The correct component values are listed in the Spare Parts List Therefore always check this list when there is any doubt
243 Lead Free Solder
Philips CE is going to produce lead-free sets (PBF) from 112005 onwards
Figure 2-2 Lead-free logo
This sign normally has a diameter of 6 mm but if there is less space on a board also 3 mm is possible Regardless of this logo (is not always present) one must treat all sets from this date onwards according to the following rules
Due to lead-free technology some rules have to be respected by the workshop during a repairbull Use only lead-free soldering tin Philips SAC305 with order
code 0622 149 00106 If lead-free solder paste is required please contact the manufacturer of your soldering equipment In general use of solder paste within workshops should be avoided because paste is not easy to store and to handle
bull Use only adequate solder tools applicable for lead-free soldering tin The solder tool must be able
ndash To reach at least a solder-tip temperature of 400degCndash To stabilise the adjusted temperature at the solder-tipndash To exchange solder-tips for different applications
bull Adjust your solder tool so that a temperature around 360degC - 380degC is reached and stabilised at the solder joint Heating time of the solder-joint should not exceed ~ 4 sec Avoid temperatures above 400degC otherwise wear-out of tips will rise drastically and flux-fluid will be destroyed To avoid wear-out of tips switch ldquooffrdquo unused equipment or reduce heat
bull Mix of lead-free soldering tinparts with leaded soldering tinparts is possible but PHILIPS recommends strongly to avoid mixed regimes If not to avoid clean carefully the solder-joint from old tin and re-solder with new tin
bull Use only original spare-parts listed in the Service-Manuals Not listed standard material (commodities) has to be purchased at external companies
bull For sets produced before 112005 containing leaded soldering tin and components all needed spare parts will be available till the end of the service period For the repair of such sets nothing changes
In case of doubt whether the board is lead-free or not (or with mixed technologies) you can use the following methodbull Always use the highest temperature to solder when using
SAC305 (see also instructions below)bull De-solder thoroughly (clean solder joints to avoid mix of
two alloys)Caution For BGA-ICs you must use the correct temperature-profile which is coupled to the 12NC For an overview of these profiles visit the website wwwatyourservicecephilipscom (needs subscription but is not available for all regions)You will find this and more technical information within the Magazine chapter Workshop informationFor additional questions please contact your local repair help desk
244 Practical Service Precautions
bull It makes sense to avoid exposure to electrical shock While some sources are expected to have a possible dangerous impact others of quite high potential are of limited current and are sometimes held in less regard
bull Always respect voltages While some may not be dangerous in themselves they can cause unexpected reactions that are best avoided Before reaching into a powered TV set it is best to test the high voltage insulation It is easy to do and is a good service precaution

54 ComPair
541 Introduction
ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products ComPair is a further development on the European DST (service remote control) which allows faster and more accurate diagnostics ComPair has three big advantagesbull ComPair helps you to quickly get an understanding on how
to repair the chassis in a short time by guiding you systematically through the repair procedures
bull ComPair allows very detailed diagnostics (on I2C level) and is therefore capable of accurately indicating problem areas You do not have to know anything about I2C commands yourself because ComPair takes care of this
bull ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available When ComPair is installed together with the SearchMan electronic manual of the defective chassis schematics and PWBs are only a mouse click away
542 Specifications
ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product The ComPair interface box is connected to the PC via a serial or RS232 cable In this chassis the ComPair interface box and the TV communicate via a bi-directional service cable via the service
Service Modes Error Codes and Fault Finding EN 9L032L AA 5
connector (located on the Main panel (see figure Top view Mono Carrier in chapter 8 Alignments) The ComPair faultfinding program is able to determine the problem of the defective television ComPair can gather diagnostic information in two waysbull Automatic (by communication with the television)
ComPair can automatically read out the contents of the entire error buffer Diagnosis is done on I2C level ComPair can access the I2C bus of the television ComPair can send and receive I2C commands to the micro controller of the television In this way it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set
bull Manually (by asking questions to you) Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extent When this is not the case ComPair will guide you through the faultfinding tree by asking you questions (eg Does the screen give a picture Click on the correct answer YES NO) and showing you examples (eg Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope) You can answer by clicking on a link (eg text or a waveform picture) that will bring you to the next step in the faultfinding process
By a combination of automatic diagnostics and an interactive question answer procedure ComPair will enable you to find most problems in a fast and effective way Besides fault finding ComPair provides some additional features likebull Up- or downloading of pre-setsbull Managing of pre-set listsbull Emulation of the Dealer Service Tool (DST)bull If both ComPair and SearchMan (Electronic Service
Manual) are installed all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink Example Measure the DC-voltage on capacitor C2568 (SchematicPanel) at the Mono-carrier ndash Click on the Panel hyperlink to automatically show the
PWB with a highlighted capacitor C2568 ndash Click on the Schematic hyperlink to automatically
show the position of the highlighted capacitor
543 How to Connect ComPair
1 First install the ComPair Browser software (see the Quick Reference Card for installation instructions)
2 Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with ldquoPCrdquo) of the ComPair interface
3 Connect the AC power adapter to the supply connector (marked with ldquoPOWER 9V DCrdquo) on the ComPair interface
4 Switch the ComPair interface OFF5 Switch the television set OFF (remove the AC power)6 Connect the ComPair interface cable between the
connector on the rear side of the ComPair interface (marked with ldquoI2Crdquo) and the ComPair connector on the mono carrier (see figure Top view Mono Carrier in chapter 8 Alignments)
7 Plug the AC power adapter in the AC power outlet and switch on the interface The green and red LEDs light up together The red LED extinguishes after approx 1 second while the green LED remains lit
8 Start the ComPair program and read the ldquointroductionrdquo chapter

545 Error Buffer
The error code buffer contains all detected errors since the last time the buffer was erased The buffer is written from left to right When an error occurs that is not yet in the error code buffer it is written at the left side and all other errors shift one position to the right
546 How To Read the Error Buffer
You can read the error buffer in 3 waysbull On screen via the SDAM (only if you have a picture)
Examplesndash ERROR 0 0 0 0 0 No errors detectedndash ERROR 6 0 0 0 0 Error code 6 is the last and only
detected errorndash ERROR 9 6 0 0 0 Error code 6 was first detected and
error code 9 is the last detected (newest) errorbull Via the blinking LED procedure (when you have no
picture) See next paragraphbull Via ComPair
547 How to Clear the Error Buffer
The error code buffer is cleared in the following casesbull By activation of the CLEAR command in the SDAM menubull If the content of the error buffer has not changed for 50
hours it resets automatically
NoteWhen leaving SDAM by disconnecting the set from AC power the error buffer is not reset

55 Error Codes
In case of non-intermittent faults clear the error buffer before you begin the repair These to ensure that old error codes are no longer present If possible check the entire contents of the error buffer In some situations an error code is only the result of another error code and not the actual cause (eg a fault in the protection detection circuitry can also lead to a protection)
Table 5-3 Error Code Table
56 The Blinking LED Procedure
Via this procedure you can make the contents of the error buffer visible via the front LED This is especially useful when there is no picture When the SDAM is entered the LED will blink the contents of the error-buffer bull n short blinks (n = 1 - 14)bull When all the error-codes are displayed the sequence
finishes with a LED blink of 3 sbull The sequence starts again
Example of error buffer 12 9 6 0 0 After entering SDAM bull 12 short blinks followed by a pause of 3 sbull 9 short blinks followed by a pause of 3 sbull 6 short blinks followed by a pause of 3 sbull 1 long blink of 3 s to finish the sequencebull the sequence starts again
57 Protections
If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode Blinking of the red LED at a frequency of 3 Hz indicates the protection mode In some error cases the microprocessor does not put the set in the protection mode The error codes of the error buffer can be read via the service menu (SDAM) the blinking LED procedure or via ComPair To get a quick diagnosis the chassis has one service modes implementedbull The Service Default Alignment Mode (SDAM) Start-up of
the set in a predefined way and adjustment of the set via a menu and with the help of test patterns
58 Repair Tips
Below some failure symptoms are given followed by a repair tipbull Set is dead and makes hiccupping sound ldquoMain
Supplyrdquo is available Hiccupping stops when de-soldering L5563 meaning that problem is in the ldquoMain Supplyrdquo line No output voltages at LOT no horizontal deflection Reason line transistor 7421 is defective
bull Set is dead and makes no sound Check power supply IC 7520 Result voltage at pins 2 6 7 9 and 11 are about 180 V and pin 14 is 0 V The reason why the voltage on these pins is so high is because the output driver (pin 11) has an open load That is why MOSFET 7521 is not able to switch Reason feedback resistor 3523 is defective Caution be careful measuring on the gate of 7521 circuitry is very high ohmic and can easily be damaged
bull Set is in hiccup mode and shuts down after 8 s Blinking LED (set in SDM mode) indicates error 5 As it is unlikely that the ldquoPORrdquo and ldquo+8V protectionrdquo happen at the same time measure the ldquo+8Vrdquo If this voltage is missing check transistor 7491 and 7496
bull Set is non-stop in hiccup mode Set is in over current mode check the secondary sensing (opto coupler 7515) and the ldquoMain Supplyrdquo voltage Signal ldquoStdby_conrdquo must be logic low under normal operation conditions and goes to high (33 V) under standby and fault conditions
bull Set turns on but without picture and sound The screen shows snow but OSD and other menus are okay Blinking LED procedure indicates error 11 so problem is expected in the tuner (pos 1000) Check presence of supply voltages As ldquoVlotaux+5Vrdquo at pin 5 and 7 are okay ldquoVT_supplyrdquo at pin 9 is missing Conclusion resistor 3449 and 3450 are defective

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)
How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

semiconductors in the unit irrespective of the type indication on these semiconductors
242 Schematic Notes
bull All resistor values are in ohms and the value multiplier is often used to indicate the decimal point location (eg 2K2 indicates 22 kohm)
bull Resistor values with no multiplier may be indicated with either an E or an R (eg 220E or 220R indicates 220 ohm)
bull All capacitor values are given in micro-farads (micro= x10-6) nano-farads (n= x10-9) or pico-farads (p= x10-12)
bull Capacitor values may also use the value multiplier as the decimal point indication (eg 2p2 indicates 22 pF)
bull An asterisk () indicates component usage varies Refer to the diversity tables for the correct values
bull The correct component values are listed in the Spare Parts List Therefore always check this list when there is any doubt
243 Lead Free Solder
Philips CE is going to produce lead-free sets (PBF) from 112005 onwards
Figure 2-2 Lead-free logo
This sign normally has a diameter of 6 mm but if there is less space on a board also 3 mm is possible Regardless of this logo (is not always present) one must treat all sets from this date onwards according to the following rules
Due to lead-free technology some rules have to be respected by the workshop during a repairbull Use only lead-free soldering tin Philips SAC305 with order
code 0622 149 00106 If lead-free solder paste is required please contact the manufacturer of your soldering equipment In general use of solder paste within workshops should be avoided because paste is not easy to store and to handle
bull Use only adequate solder tools applicable for lead-free soldering tin The solder tool must be able
ndash To reach at least a solder-tip temperature of 400degCndash To stabilise the adjusted temperature at the solder-tipndash To exchange solder-tips for different applications
bull Adjust your solder tool so that a temperature around 360degC - 380degC is reached and stabilised at the solder joint Heating time of the solder-joint should not exceed ~ 4 sec Avoid temperatures above 400degC otherwise wear-out of tips will rise drastically and flux-fluid will be destroyed To avoid wear-out of tips switch ldquooffrdquo unused equipment or reduce heat
bull Mix of lead-free soldering tinparts with leaded soldering tinparts is possible but PHILIPS recommends strongly to avoid mixed regimes If not to avoid clean carefully the solder-joint from old tin and re-solder with new tin
bull Use only original spare-parts listed in the Service-Manuals Not listed standard material (commodities) has to be purchased at external companies
bull For sets produced before 112005 containing leaded soldering tin and components all needed spare parts will be available till the end of the service period For the repair of such sets nothing changes
In case of doubt whether the board is lead-free or not (or with mixed technologies) you can use the following methodbull Always use the highest temperature to solder when using
SAC305 (see also instructions below)bull De-solder thoroughly (clean solder joints to avoid mix of
two alloys)Caution For BGA-ICs you must use the correct temperature-profile which is coupled to the 12NC For an overview of these profiles visit the website wwwatyourservicecephilipscom (needs subscription but is not available for all regions)You will find this and more technical information within the Magazine chapter Workshop informationFor additional questions please contact your local repair help desk
244 Practical Service Precautions
bull It makes sense to avoid exposure to electrical shock While some sources are expected to have a possible dangerous impact others of quite high potential are of limited current and are sometimes held in less regard
bull Always respect voltages While some may not be dangerous in themselves they can cause unexpected reactions that are best avoided Before reaching into a powered TV set it is best to test the high voltage insulation It is easy to do and is a good service precaution

54 ComPair
541 Introduction
ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products ComPair is a further development on the European DST (service remote control) which allows faster and more accurate diagnostics ComPair has three big advantagesbull ComPair helps you to quickly get an understanding on how
to repair the chassis in a short time by guiding you systematically through the repair procedures
bull ComPair allows very detailed diagnostics (on I2C level) and is therefore capable of accurately indicating problem areas You do not have to know anything about I2C commands yourself because ComPair takes care of this
bull ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available When ComPair is installed together with the SearchMan electronic manual of the defective chassis schematics and PWBs are only a mouse click away
542 Specifications
ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product The ComPair interface box is connected to the PC via a serial or RS232 cable In this chassis the ComPair interface box and the TV communicate via a bi-directional service cable via the service
Service Modes Error Codes and Fault Finding EN 9L032L AA 5
connector (located on the Main panel (see figure Top view Mono Carrier in chapter 8 Alignments) The ComPair faultfinding program is able to determine the problem of the defective television ComPair can gather diagnostic information in two waysbull Automatic (by communication with the television)
ComPair can automatically read out the contents of the entire error buffer Diagnosis is done on I2C level ComPair can access the I2C bus of the television ComPair can send and receive I2C commands to the micro controller of the television In this way it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set
bull Manually (by asking questions to you) Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extent When this is not the case ComPair will guide you through the faultfinding tree by asking you questions (eg Does the screen give a picture Click on the correct answer YES NO) and showing you examples (eg Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope) You can answer by clicking on a link (eg text or a waveform picture) that will bring you to the next step in the faultfinding process
By a combination of automatic diagnostics and an interactive question answer procedure ComPair will enable you to find most problems in a fast and effective way Besides fault finding ComPair provides some additional features likebull Up- or downloading of pre-setsbull Managing of pre-set listsbull Emulation of the Dealer Service Tool (DST)bull If both ComPair and SearchMan (Electronic Service
Manual) are installed all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink Example Measure the DC-voltage on capacitor C2568 (SchematicPanel) at the Mono-carrier ndash Click on the Panel hyperlink to automatically show the
PWB with a highlighted capacitor C2568 ndash Click on the Schematic hyperlink to automatically
show the position of the highlighted capacitor
543 How to Connect ComPair
1 First install the ComPair Browser software (see the Quick Reference Card for installation instructions)
2 Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with ldquoPCrdquo) of the ComPair interface
3 Connect the AC power adapter to the supply connector (marked with ldquoPOWER 9V DCrdquo) on the ComPair interface
4 Switch the ComPair interface OFF5 Switch the television set OFF (remove the AC power)6 Connect the ComPair interface cable between the
connector on the rear side of the ComPair interface (marked with ldquoI2Crdquo) and the ComPair connector on the mono carrier (see figure Top view Mono Carrier in chapter 8 Alignments)
7 Plug the AC power adapter in the AC power outlet and switch on the interface The green and red LEDs light up together The red LED extinguishes after approx 1 second while the green LED remains lit
8 Start the ComPair program and read the ldquointroductionrdquo chapter

545 Error Buffer
The error code buffer contains all detected errors since the last time the buffer was erased The buffer is written from left to right When an error occurs that is not yet in the error code buffer it is written at the left side and all other errors shift one position to the right
546 How To Read the Error Buffer
You can read the error buffer in 3 waysbull On screen via the SDAM (only if you have a picture)
Examplesndash ERROR 0 0 0 0 0 No errors detectedndash ERROR 6 0 0 0 0 Error code 6 is the last and only
detected errorndash ERROR 9 6 0 0 0 Error code 6 was first detected and
error code 9 is the last detected (newest) errorbull Via the blinking LED procedure (when you have no
picture) See next paragraphbull Via ComPair
547 How to Clear the Error Buffer
The error code buffer is cleared in the following casesbull By activation of the CLEAR command in the SDAM menubull If the content of the error buffer has not changed for 50
hours it resets automatically
NoteWhen leaving SDAM by disconnecting the set from AC power the error buffer is not reset

55 Error Codes
In case of non-intermittent faults clear the error buffer before you begin the repair These to ensure that old error codes are no longer present If possible check the entire contents of the error buffer In some situations an error code is only the result of another error code and not the actual cause (eg a fault in the protection detection circuitry can also lead to a protection)
Table 5-3 Error Code Table
56 The Blinking LED Procedure
Via this procedure you can make the contents of the error buffer visible via the front LED This is especially useful when there is no picture When the SDAM is entered the LED will blink the contents of the error-buffer bull n short blinks (n = 1 - 14)bull When all the error-codes are displayed the sequence
finishes with a LED blink of 3 sbull The sequence starts again
Example of error buffer 12 9 6 0 0 After entering SDAM bull 12 short blinks followed by a pause of 3 sbull 9 short blinks followed by a pause of 3 sbull 6 short blinks followed by a pause of 3 sbull 1 long blink of 3 s to finish the sequencebull the sequence starts again
57 Protections
If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode Blinking of the red LED at a frequency of 3 Hz indicates the protection mode In some error cases the microprocessor does not put the set in the protection mode The error codes of the error buffer can be read via the service menu (SDAM) the blinking LED procedure or via ComPair To get a quick diagnosis the chassis has one service modes implementedbull The Service Default Alignment Mode (SDAM) Start-up of
the set in a predefined way and adjustment of the set via a menu and with the help of test patterns
58 Repair Tips
Below some failure symptoms are given followed by a repair tipbull Set is dead and makes hiccupping sound ldquoMain
Supplyrdquo is available Hiccupping stops when de-soldering L5563 meaning that problem is in the ldquoMain Supplyrdquo line No output voltages at LOT no horizontal deflection Reason line transistor 7421 is defective
bull Set is dead and makes no sound Check power supply IC 7520 Result voltage at pins 2 6 7 9 and 11 are about 180 V and pin 14 is 0 V The reason why the voltage on these pins is so high is because the output driver (pin 11) has an open load That is why MOSFET 7521 is not able to switch Reason feedback resistor 3523 is defective Caution be careful measuring on the gate of 7521 circuitry is very high ohmic and can easily be damaged
bull Set is in hiccup mode and shuts down after 8 s Blinking LED (set in SDM mode) indicates error 5 As it is unlikely that the ldquoPORrdquo and ldquo+8V protectionrdquo happen at the same time measure the ldquo+8Vrdquo If this voltage is missing check transistor 7491 and 7496
bull Set is non-stop in hiccup mode Set is in over current mode check the secondary sensing (opto coupler 7515) and the ldquoMain Supplyrdquo voltage Signal ldquoStdby_conrdquo must be logic low under normal operation conditions and goes to high (33 V) under standby and fault conditions
bull Set turns on but without picture and sound The screen shows snow but OSD and other menus are okay Blinking LED procedure indicates error 11 so problem is expected in the tuner (pos 1000) Check presence of supply voltages As ldquoVlotaux+5Vrdquo at pin 5 and 7 are okay ldquoVT_supplyrdquo at pin 9 is missing Conclusion resistor 3449 and 3450 are defective

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)
How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

54 ComPair
541 Introduction
ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products ComPair is a further development on the European DST (service remote control) which allows faster and more accurate diagnostics ComPair has three big advantagesbull ComPair helps you to quickly get an understanding on how
to repair the chassis in a short time by guiding you systematically through the repair procedures
bull ComPair allows very detailed diagnostics (on I2C level) and is therefore capable of accurately indicating problem areas You do not have to know anything about I2C commands yourself because ComPair takes care of this
bull ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available When ComPair is installed together with the SearchMan electronic manual of the defective chassis schematics and PWBs are only a mouse click away
542 Specifications
ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product The ComPair interface box is connected to the PC via a serial or RS232 cable In this chassis the ComPair interface box and the TV communicate via a bi-directional service cable via the service

connector (located on the Main panel (see figure Top view Mono Carrier in chapter 8 Alignments) The ComPair faultfinding program is able to determine the problem of the defective television ComPair can gather diagnostic information in two waysbull Automatic (by communication with the television)
ComPair can automatically read out the contents of the entire error buffer Diagnosis is done on I2C level ComPair can access the I2C bus of the television ComPair can send and receive I2C commands to the micro controller of the television In this way it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set
bull Manually (by asking questions to you) Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extent When this is not the case ComPair will guide you through the faultfinding tree by asking you questions (eg Does the screen give a picture Click on the correct answer YES NO) and showing you examples (eg Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope) You can answer by clicking on a link (eg text or a waveform picture) that will bring you to the next step in the faultfinding process
By a combination of automatic diagnostics and an interactive question answer procedure ComPair will enable you to find most problems in a fast and effective way Besides fault finding ComPair provides some additional features likebull Up- or downloading of pre-setsbull Managing of pre-set listsbull Emulation of the Dealer Service Tool (DST)bull If both ComPair and SearchMan (Electronic Service
Manual) are installed all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink Example Measure the DC-voltage on capacitor C2568 (SchematicPanel) at the Mono-carrier ndash Click on the Panel hyperlink to automatically show the
PWB with a highlighted capacitor C2568 ndash Click on the Schematic hyperlink to automatically
show the position of the highlighted capacitor
543 How to Connect ComPair
1 First install the ComPair Browser software (see the Quick Reference Card for installation instructions)
2 Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with ldquoPCrdquo) of the ComPair interface
3 Connect the AC power adapter to the supply connector (marked with ldquoPOWER 9V DCrdquo) on the ComPair interface
4 Switch the ComPair interface OFF5 Switch the television set OFF (remove the AC power)6 Connect the ComPair interface cable between the
connector on the rear side of the ComPair interface (marked with ldquoI2Crdquo) and the ComPair connector on the mono carrier (see figure Top view Mono Carrier in chapter 8 Alignments)
7 Plug the AC power adapter in the AC power outlet and switch on the interface The green and red LEDs light up together The red LED extinguishes after approx 1 second while the green LED remains lit
8 Start the ComPair program and read the ldquointroductionrdquo chapter

545 Error Buffer
The error code buffer contains all detected errors since the last time the buffer was erased The buffer is written from left to right When an error occurs that is not yet in the error code buffer it is written at the left side and all other errors shift one position to the right
546 How To Read the Error Buffer
You can read the error buffer in 3 waysbull On screen via the SDAM (only if you have a picture)
Examplesndash ERROR 0 0 0 0 0 No errors detectedndash ERROR 6 0 0 0 0 Error code 6 is the last and only
detected errorndash ERROR 9 6 0 0 0 Error code 6 was first detected and
error code 9 is the last detected (newest) errorbull Via the blinking LED procedure (when you have no
picture) See next paragraphbull Via ComPair
547 How to Clear the Error Buffer
The error code buffer is cleared in the following casesbull By activation of the CLEAR command in the SDAM menubull If the content of the error buffer has not changed for 50
hours it resets automatically
NoteWhen leaving SDAM by disconnecting the set from AC power the error buffer is not reset

55 Error Codes
In case of non-intermittent faults clear the error buffer before you begin the repair These to ensure that old error codes are no longer present If possible check the entire contents of the error buffer In some situations an error code is only the result of another error code and not the actual cause (eg a fault in the protection detection circuitry can also lead to a protection)
Table 5-3 Error Code Table
56 The Blinking LED Procedure
Via this procedure you can make the contents of the error buffer visible via the front LED This is especially useful when there is no picture When the SDAM is entered the LED will blink the contents of the error-buffer bull n short blinks (n = 1 - 14)bull When all the error-codes are displayed the sequence
finishes with a LED blink of 3 sbull The sequence starts again
Example of error buffer 12 9 6 0 0 After entering SDAM bull 12 short blinks followed by a pause of 3 sbull 9 short blinks followed by a pause of 3 sbull 6 short blinks followed by a pause of 3 sbull 1 long blink of 3 s to finish the sequencebull the sequence starts again
57 Protections
If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode Blinking of the red LED at a frequency of 3 Hz indicates the protection mode In some error cases the microprocessor does not put the set in the protection mode The error codes of the error buffer can be read via the service menu (SDAM) the blinking LED procedure or via ComPair To get a quick diagnosis the chassis has one service modes implementedbull The Service Default Alignment Mode (SDAM) Start-up of
the set in a predefined way and adjustment of the set via a menu and with the help of test patterns
58 Repair Tips
Below some failure symptoms are given followed by a repair tipbull Set is dead and makes hiccupping sound ldquoMain
Supplyrdquo is available Hiccupping stops when de-soldering L5563 meaning that problem is in the ldquoMain Supplyrdquo line No output voltages at LOT no horizontal deflection Reason line transistor 7421 is defective
bull Set is dead and makes no sound Check power supply IC 7520 Result voltage at pins 2 6 7 9 and 11 are about 180 V and pin 14 is 0 V The reason why the voltage on these pins is so high is because the output driver (pin 11) has an open load That is why MOSFET 7521 is not able to switch Reason feedback resistor 3523 is defective Caution be careful measuring on the gate of 7521 circuitry is very high ohmic and can easily be damaged
bull Set is in hiccup mode and shuts down after 8 s Blinking LED (set in SDM mode) indicates error 5 As it is unlikely that the ldquoPORrdquo and ldquo+8V protectionrdquo happen at the same time measure the ldquo+8Vrdquo If this voltage is missing check transistor 7491 and 7496
bull Set is non-stop in hiccup mode Set is in over current mode check the secondary sensing (opto coupler 7515) and the ldquoMain Supplyrdquo voltage Signal ldquoStdby_conrdquo must be logic low under normal operation conditions and goes to high (33 V) under standby and fault conditions
bull Set turns on but without picture and sound The screen shows snow but OSD and other menus are okay Blinking LED procedure indicates error 11 so problem is expected in the tuner (pos 1000) Check presence of supply voltages As ldquoVlotaux+5Vrdquo at pin 5 and 7 are okay ldquoVT_supplyrdquo at pin 9 is missing Conclusion resistor 3449 and 3450 are defective

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)
How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

54 ComPair
541 Introduction
ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products ComPair is a further development on the European DST (service remote control) which allows faster and more accurate diagnostics ComPair has three big advantagesbull ComPair helps you to quickly get an understanding on how
to repair the chassis in a short time by guiding you systematically through the repair procedures
bull ComPair allows very detailed diagnostics (on I2C level) and is therefore capable of accurately indicating problem areas You do not have to know anything about I2C commands yourself because ComPair takes care of this
bull ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available When ComPair is installed together with the SearchMan electronic manual of the defective chassis schematics and PWBs are only a mouse click away
542 Specifications
ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product The ComPair interface box is connected to the PC via a serial or RS232 cable In this chassis the ComPair interface box and the TV communicate via a bi-directional service cable via the service

connector (located on the Main panel (see figure Top view Mono Carrier in chapter 8 Alignments) The ComPair faultfinding program is able to determine the problem of the defective television ComPair can gather diagnostic information in two waysbull Automatic (by communication with the television)
ComPair can automatically read out the contents of the entire error buffer Diagnosis is done on I2C level ComPair can access the I2C bus of the television ComPair can send and receive I2C commands to the micro controller of the television In this way it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set
bull Manually (by asking questions to you) Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extent When this is not the case ComPair will guide you through the faultfinding tree by asking you questions (eg Does the screen give a picture Click on the correct answer YES NO) and showing you examples (eg Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope) You can answer by clicking on a link (eg text or a waveform picture) that will bring you to the next step in the faultfinding process
By a combination of automatic diagnostics and an interactive question answer procedure ComPair will enable you to find most problems in a fast and effective way Besides fault finding ComPair provides some additional features likebull Up- or downloading of pre-setsbull Managing of pre-set listsbull Emulation of the Dealer Service Tool (DST)bull If both ComPair and SearchMan (Electronic Service
Manual) are installed all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink Example Measure the DC-voltage on capacitor C2568 (SchematicPanel) at the Mono-carrier ndash Click on the Panel hyperlink to automatically show the
PWB with a highlighted capacitor C2568 ndash Click on the Schematic hyperlink to automatically
show the position of the highlighted capacitor
543 How to Connect ComPair
1 First install the ComPair Browser software (see the Quick Reference Card for installation instructions)
2 Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with ldquoPCrdquo) of the ComPair interface
3 Connect the AC power adapter to the supply connector (marked with ldquoPOWER 9V DCrdquo) on the ComPair interface
4 Switch the ComPair interface OFF5 Switch the television set OFF (remove the AC power)6 Connect the ComPair interface cable between the
connector on the rear side of the ComPair interface (marked with ldquoI2Crdquo) and the ComPair connector on the mono carrier (see figure Top view Mono Carrier in chapter 8 Alignments)
7 Plug the AC power adapter in the AC power outlet and switch on the interface The green and red LEDs light up together The red LED extinguishes after approx 1 second while the green LED remains lit
8 Start the ComPair program and read the ldquointroductionrdquo chapter

545 Error Buffer
The error code buffer contains all detected errors since the last time the buffer was erased The buffer is written from left to right When an error occurs that is not yet in the error code buffer it is written at the left side and all other errors shift one position to the right
546 How To Read the Error Buffer
You can read the error buffer in 3 waysbull On screen via the SDAM (only if you have a picture)
Examplesndash ERROR 0 0 0 0 0 No errors detectedndash ERROR 6 0 0 0 0 Error code 6 is the last and only
detected errorndash ERROR 9 6 0 0 0 Error code 6 was first detected and
error code 9 is the last detected (newest) errorbull Via the blinking LED procedure (when you have no
picture) See next paragraphbull Via ComPair
547 How to Clear the Error Buffer
The error code buffer is cleared in the following casesbull By activation of the CLEAR command in the SDAM menubull If the content of the error buffer has not changed for 50
hours it resets automatically
NoteWhen leaving SDAM by disconnecting the set from AC power the error buffer is not reset

Service Modes Error Codes and Fault FindingEN 10 L032L AA5
55 Error Codes
In case of non-intermittent faults clear the error buffer before you begin the repair These to ensure that old error codes are no longer present If possible check the entire contents of the error buffer In some situations an error code is only the result of another error code and not the actual cause (eg a fault in the protection detection circuitry can also lead to a protection)
Table 5-3 Error Code Table
56 The Blinking LED Procedure
Via this procedure you can make the contents of the error buffer visible via the front LED This is especially useful when there is no picture When the SDAM is entered the LED will blink the contents of the error-buffer bull n short blinks (n = 1 - 14)bull When all the error-codes are displayed the sequence
finishes with a LED blink of 3 sbull The sequence starts again
Example of error buffer 12 9 6 0 0 After entering SDAM bull 12 short blinks followed by a pause of 3 sbull 9 short blinks followed by a pause of 3 sbull 6 short blinks followed by a pause of 3 sbull 1 long blink of 3 s to finish the sequencebull the sequence starts again
57 Protections
If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode Blinking of the red LED at a frequency of 3 Hz indicates the protection mode In some error cases the microprocessor does not put the set in the protection mode The error codes of the error buffer can be read via the service menu (SDAM) the blinking LED procedure or via ComPair To get a quick diagnosis the chassis has one service modes implementedbull The Service Default Alignment Mode (SDAM) Start-up of
the set in a predefined way and adjustment of the set via a menu and with the help of test patterns
58 Repair Tips
Below some failure symptoms are given followed by a repair tipbull Set is dead and makes hiccupping sound ldquoMain
Supplyrdquo is available Hiccupping stops when de-soldering L5563 meaning that problem is in the ldquoMain Supplyrdquo line No output voltages at LOT no horizontal deflection Reason line transistor 7421 is defective
bull Set is dead and makes no sound Check power supply IC 7520 Result voltage at pins 2 6 7 9 and 11 are about 180 V and pin 14 is 0 V The reason why the voltage on these pins is so high is because the output driver (pin 11) has an open load That is why MOSFET 7521 is not able to switch Reason feedback resistor 3523 is defective Caution be careful measuring on the gate of 7521 circuitry is very high ohmic and can easily be damaged
bull Set is in hiccup mode and shuts down after 8 s Blinking LED (set in SDM mode) indicates error 5 As it is unlikely that the ldquoPORrdquo and ldquo+8V protectionrdquo happen at the same time measure the ldquo+8Vrdquo If this voltage is missing check transistor 7491 and 7496
bull Set is non-stop in hiccup mode Set is in over current mode check the secondary sensing (opto coupler 7515) and the ldquoMain Supplyrdquo voltage Signal ldquoStdby_conrdquo must be logic low under normal operation conditions and goes to high (33 V) under standby and fault conditions
bull Set turns on but without picture and sound The screen shows snow but OSD and other menus are okay Blinking LED procedure indicates error 11 so problem is expected in the tuner (pos 1000) Check presence of supply voltages As ldquoVlotaux+5Vrdquo at pin 5 and 7 are okay ldquoVT_supplyrdquo at pin 9 is missing Conclusion resistor 3449 and 3450 are defective

Note The Service Default Alignment Mode (SDAM) is described in the Service Modes Error Codes and Fault Finding section SDAM menu navigation is performed by using the MENU UP MENU DOWN MENU LEFT and MENU RIGHT keys of the remote control transmitter
81 General Alignment Conditions
Perform all electrical adjustments under the following conditionsbull AC voltage and frequency according to countrys
standardbull Connect the television set to the AC power via an isolation
transformerbull Allow the television set to warm up for approximately 20
minutesbull Measure the voltages and waveforms in relation to chassis
ground (with the exception of the voltages on the primary side of the power supply) Never use heatsinks as ground
bull Test probe Ri gt 10 M ohm Ci lt 25 pFbull Use an isolated trimmerscrewdriver to perform the
alignments

1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the WHITE TONE sub menu
3 Press the MENU LEFTRIGHT key to enter the WHITE TONE sub menu
4 In the WHITE TONE sub menu press the MENU UPDOWN keys to select NORMAL RED NORMAL GREEN or NORMAL BLUE
5 Use the MENU LEFTRIGHT keys to set the values of NORMAL RED NORMAL GREEN and NORMAL BLUE to 40
6 Press the MENU button twice to enter the normal user menu
7 In the normal user menu use the MENU UPDOWN keys to highlight the PICTURE sub menu (if necessary)
8 Press the MENU LEFTRIGHT keys to enter the PICTURE sub menu
9 Use the MENU UPDOWN keys to select CONTRAST Be sure to record the current value of CONTRAST
10 Use the MENU LEFTRIGHT keys to set the value of CONTRAST to 0
11 Use the MENU UPDOWN keys to select BRIGHTNESS Be sure to record the current value of BRIGHTNESS
12 Use the MENU LEFTRIGHT keys to set the value of BRIGHTNESS to minimum (OSD just visible in a dark room)
13 Press the MENU button twice to return to the top level SDAM menu
14 Press the OSDSTATUS button to hide the SDAM onscreen display (S indication remains visible) This to avoid interferences during the waveform measurements
15 Connect the RF output of a video pattern generator to the antenna input and input a black picture test pattern to the television set
16 Set the oscilloscope to 50 Vdiv and the time base to 02 milliseconds (external triggering on the positive vertical pulse with a 101 probe)
17 Ground the scope at the CRT panel and connect a 1001 probe to one of the cathodes of the picture tube socket (pin 7= Red pin 9= Green and pin 3= Blue see also schematic diagram B1) Measure the level of the black current measuring pulses These are the second line (Red) third line (Green) and fourth line (Blue) directly after the frame blanking (see figure Vcut-off) Remark This chassis is using a TDA93XX UOC series These use two different measuring pulses at each of the R G and B outputs The above-mentioned level applies to the pulse with the lowest level of each gun
18 Select the cathode with the highest VDC value for the alignment Adjust the Vcut-off of this gun with the SCREEN potentiometer (see figure Top view family board) on the LOT to the correct value (see table Vg2 alignment values)
19 Press the OSDSTATUS button to display the SDAM onscreen display

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)
How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

54 ComPair
541 Introduction
ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products ComPair is a further development on the European DST (service remote control) which allows faster and more accurate diagnostics ComPair has three big advantagesbull ComPair helps you to quickly get an understanding on how
to repair the chassis in a short time by guiding you systematically through the repair procedures
bull ComPair allows very detailed diagnostics (on I2C level) and is therefore capable of accurately indicating problem areas You do not have to know anything about I2C commands yourself because ComPair takes care of this
bull ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available When ComPair is installed together with the SearchMan electronic manual of the defective chassis schematics and PWBs are only a mouse click away
542 Specifications
ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product The ComPair interface box is connected to the PC via a serial or RS232 cable In this chassis the ComPair interface box and the TV communicate via a bi-directional service cable via the service

connector (located on the Main panel (see figure Top view Mono Carrier in chapter 8 Alignments) The ComPair faultfinding program is able to determine the problem of the defective television ComPair can gather diagnostic information in two waysbull Automatic (by communication with the television)
ComPair can automatically read out the contents of the entire error buffer Diagnosis is done on I2C level ComPair can access the I2C bus of the television ComPair can send and receive I2C commands to the micro controller of the television In this way it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set
bull Manually (by asking questions to you) Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extent When this is not the case ComPair will guide you through the faultfinding tree by asking you questions (eg Does the screen give a picture Click on the correct answer YES NO) and showing you examples (eg Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope) You can answer by clicking on a link (eg text or a waveform picture) that will bring you to the next step in the faultfinding process
By a combination of automatic diagnostics and an interactive question answer procedure ComPair will enable you to find most problems in a fast and effective way Besides fault finding ComPair provides some additional features likebull Up- or downloading of pre-setsbull Managing of pre-set listsbull Emulation of the Dealer Service Tool (DST)bull If both ComPair and SearchMan (Electronic Service
Manual) are installed all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink Example Measure the DC-voltage on capacitor C2568 (SchematicPanel) at the Mono-carrier ndash Click on the Panel hyperlink to automatically show the
PWB with a highlighted capacitor C2568 ndash Click on the Schematic hyperlink to automatically
show the position of the highlighted capacitor
543 How to Connect ComPair
1 First install the ComPair Browser software (see the Quick Reference Card for installation instructions)
2 Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with ldquoPCrdquo) of the ComPair interface
3 Connect the AC power adapter to the supply connector (marked with ldquoPOWER 9V DCrdquo) on the ComPair interface
4 Switch the ComPair interface OFF5 Switch the television set OFF (remove the AC power)6 Connect the ComPair interface cable between the
connector on the rear side of the ComPair interface (marked with ldquoI2Crdquo) and the ComPair connector on the mono carrier (see figure Top view Mono Carrier in chapter 8 Alignments)
7 Plug the AC power adapter in the AC power outlet and switch on the interface The green and red LEDs light up together The red LED extinguishes after approx 1 second while the green LED remains lit

545 Error Buffer
The error code buffer contains all detected errors since the last time the buffer was erased The buffer is written from left to right When an error occurs that is not yet in the error code buffer it is written at the left side and all other errors shift one position to the right
546 How To Read the Error Buffer
You can read the error buffer in 3 waysbull On screen via the SDAM (only if you have a picture)
Examplesndash ERROR 0 0 0 0 0 No errors detectedndash ERROR 6 0 0 0 0 Error code 6 is the last and only
detected errorndash ERROR 9 6 0 0 0 Error code 6 was first detected and
error code 9 is the last detected (newest) errorbull Via the blinking LED procedure (when you have no
picture) See next paragraphbull Via ComPair
547 How to Clear the Error Buffer
The error code buffer is cleared in the following casesbull By activation of the CLEAR command in the SDAM menubull If the content of the error buffer has not changed for 50
hours it resets automatically
NoteWhen leaving SDAM by disconnecting the set from AC power the error buffer is not reset

55 Error Codes
In case of non-intermittent faults clear the error buffer before you begin the repair These to ensure that old error codes are no longer present If possible check the entire contents of the error buffer In some situations an error code is only the result of another error code and not the actual cause (eg a fault in the protection detection circuitry can also lead to a protection)
Table 5-3 Error Code Table
56 The Blinking LED Procedure
Via this procedure you can make the contents of the error buffer visible via the front LED This is especially useful when there is no picture When the SDAM is entered the LED will blink the contents of the error-buffer bull n short blinks (n = 1 - 14)bull When all the error-codes are displayed the sequence
finishes with a LED blink of 3 sbull The sequence starts again
Example of error buffer 12 9 6 0 0 After entering SDAM bull 12 short blinks followed by a pause of 3 sbull 9 short blinks followed by a pause of 3 sbull 6 short blinks followed by a pause of 3 sbull 1 long blink of 3 s to finish the sequencebull the sequence starts again
57 Protections
If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode Blinking of the red LED at a frequency of 3 Hz indicates the protection mode In some error cases the microprocessor does not put the set in the protection mode The error codes of the error buffer can be read via the service menu (SDAM) the blinking LED procedure or via ComPair To get a quick diagnosis the chassis has one service modes implementedbull The Service Default Alignment Mode (SDAM) Start-up of
the set in a predefined way and adjustment of the set via a menu and with the help of test patterns
58 Repair Tips
Below some failure symptoms are given followed by a repair tipbull Set is dead and makes hiccupping sound ldquoMain
Supplyrdquo is available Hiccupping stops when de-soldering L5563 meaning that problem is in the ldquoMain Supplyrdquo line No output voltages at LOT no horizontal deflection Reason line transistor 7421 is defective
bull Set is dead and makes no sound Check power supply IC 7520 Result voltage at pins 2 6 7 9 and 11 are about 180 V and pin 14 is 0 V The reason why the voltage on these pins is so high is because the output driver (pin 11) has an open load That is why MOSFET 7521 is not able to switch Reason feedback resistor 3523 is defective Caution be careful measuring on the gate of 7521 circuitry is very high ohmic and can easily be damaged
bull Set is in hiccup mode and shuts down after 8 s Blinking LED (set in SDM mode) indicates error 5 As it is unlikely that the ldquoPORrdquo and ldquo+8V protectionrdquo happen at the same time measure the ldquo+8Vrdquo If this voltage is missing check transistor 7491 and 7496
bull Set is non-stop in hiccup mode Set is in over current mode check the secondary sensing (opto coupler 7515) and the ldquoMain Supplyrdquo voltage Signal ldquoStdby_conrdquo must be logic low under normal operation conditions and goes to high (33 V) under standby and fault conditions
bull Set turns on but without picture and sound The screen shows snow but OSD and other menus are okay Blinking LED procedure indicates error 11 so problem is expected in the tuner (pos 1000) Check presence of supply voltages As ldquoVlotaux+5Vrdquo at pin 5 and 7 are okay ldquoVT_supplyrdquo at pin 9 is missing Conclusion resistor 3449 and 3450 are defective

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard

How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

bull For a good understanding of the following circuit descriptions please use the block diagram in chapter 6 andor the electrical diagrams in chapter 7 Where necessary you will find a separate drawing for clarification
91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC

971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)
I2C protectionTo check whether all I2C ICs are functioning

connector (located on the Main panel (see figure Top view Mono Carrier in chapter 8 Alignments) The ComPair faultfinding program is able to determine the problem of the defective television ComPair can gather diagnostic information in two waysbull Automatic (by communication with the television)
ComPair can automatically read out the contents of the entire error buffer Diagnosis is done on I2C level ComPair can access the I2C bus of the television ComPair can send and receive I2C commands to the micro controller of the television In this way it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set
bull Manually (by asking questions to you) Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extent When this is not the case ComPair will guide you through the faultfinding tree by asking you questions (eg Does the screen give a picture Click on the correct answer YES NO) and showing you examples (eg Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope) You can answer by clicking on a link (eg text or a waveform picture) that will bring you to the next step in the faultfinding process
By a combination of automatic diagnostics and an interactive question answer procedure ComPair will enable you to find most problems in a fast and effective way Besides fault finding ComPair provides some additional features likebull Up- or downloading of pre-setsbull Managing of pre-set listsbull Emulation of the Dealer Service Tool (DST)bull If both ComPair and SearchMan (Electronic Service
Manual) are installed all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink Example Measure the DC-voltage on capacitor C2568 (SchematicPanel) at the Mono-carrier ndash Click on the Panel hyperlink to automatically show the
PWB with a highlighted capacitor C2568 ndash Click on the Schematic hyperlink to automatically
show the position of the highlighted capacitor
543 How to Connect ComPair
1 First install the ComPair Browser software (see the Quick Reference Card for installation instructions)
2 Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with ldquoPCrdquo) of the ComPair interface
3 Connect the AC power adapter to the supply connector (marked with ldquoPOWER 9V DCrdquo) on the ComPair interface
4 Switch the ComPair interface OFF5 Switch the television set OFF (remove the AC power)6 Connect the ComPair interface cable between the
connector on the rear side of the ComPair interface (marked with ldquoI2Crdquo) and the ComPair connector on the mono carrier (see figure Top view Mono Carrier in chapter 8 Alignments)
7 Plug the AC power adapter in the AC power outlet and switch on the interface The green and red LEDs light up together The red LED extinguishes after approx 1 second while the green LED remains lit
8 Start the ComPair program and read the ldquointroductionrdquo chapter

545 Error Buffer
The error code buffer contains all detected errors since the last time the buffer was erased The buffer is written from left to right When an error occurs that is not yet in the error code buffer it is written at the left side and all other errors shift one position to the right
546 How To Read the Error Buffer
You can read the error buffer in 3 waysbull On screen via the SDAM (only if you have a picture)
Examplesndash ERROR 0 0 0 0 0 No errors detectedndash ERROR 6 0 0 0 0 Error code 6 is the last and only
detected errorndash ERROR 9 6 0 0 0 Error code 6 was first detected and
error code 9 is the last detected (newest) errorbull Via the blinking LED procedure (when you have no
picture) See next paragraphbull Via ComPair
547 How to Clear the Error Buffer
The error code buffer is cleared in the following casesbull By activation of the CLEAR command in the SDAM menubull If the content of the error buffer has not changed for 50
hours it resets automatically
NoteWhen leaving SDAM by disconnecting the set from AC power the error buffer is not reset

Service Modes Error Codes and Fault FindingEN 10 L032L AA5
55 Error Codes
In case of non-intermittent faults clear the error buffer before you begin the repair These to ensure that old error codes are no longer present If possible check the entire contents of the error buffer In some situations an error code is only the result of another error code and not the actual cause (eg a fault in the protection detection circuitry can also lead to a protection)
Table 5-3 Error Code Table
56 The Blinking LED Procedure
Via this procedure you can make the contents of the error buffer visible via the front LED This is especially useful when there is no picture When the SDAM is entered the LED will blink the contents of the error-buffer bull n short blinks (n = 1 - 14)bull When all the error-codes are displayed the sequence
finishes with a LED blink of 3 sbull The sequence starts again
Example of error buffer 12 9 6 0 0 After entering SDAM bull 12 short blinks followed by a pause of 3 sbull 9 short blinks followed by a pause of 3 sbull 6 short blinks followed by a pause of 3 sbull 1 long blink of 3 s to finish the sequencebull the sequence starts again
57 Protections
If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode Blinking of the red LED at a frequency of 3 Hz indicates the protection mode In some error cases the microprocessor does not put the set in the protection mode The error codes of the error buffer can be read via the service menu (SDAM) the blinking LED procedure or via ComPair To get a quick diagnosis the chassis has one service modes implementedbull The Service Default Alignment Mode (SDAM) Start-up of
the set in a predefined way and adjustment of the set via a menu and with the help of test patterns
58 Repair Tips
Below some failure symptoms are given followed by a repair tipbull Set is dead and makes hiccupping sound ldquoMain
Supplyrdquo is available Hiccupping stops when de-soldering L5563 meaning that problem is in the ldquoMain Supplyrdquo line No output voltages at LOT no horizontal deflection Reason line transistor 7421 is defective
bull Set is dead and makes no sound Check power supply IC 7520 Result voltage at pins 2 6 7 9 and 11 are about 180 V and pin 14 is 0 V The reason why the voltage on these pins is so high is because the output driver (pin 11) has an open load That is why MOSFET 7521 is not able to switch Reason feedback resistor 3523 is defective Caution be careful measuring on the gate of 7521 circuitry is very high ohmic and can easily be damaged
bull Set is in hiccup mode and shuts down after 8 s Blinking LED (set in SDM mode) indicates error 5 As it is unlikely that the ldquoPORrdquo and ldquo+8V protectionrdquo happen at the same time measure the ldquo+8Vrdquo If this voltage is missing check transistor 7491 and 7496
bull Set is non-stop in hiccup mode Set is in over current mode check the secondary sensing (opto coupler 7515) and the ldquoMain Supplyrdquo voltage Signal ldquoStdby_conrdquo must be logic low under normal operation conditions and goes to high (33 V) under standby and fault conditions
bull Set turns on but without picture and sound The screen shows snow but OSD and other menus are okay Blinking LED procedure indicates error 11 so problem is expected in the tuner (pos 1000) Check presence of supply voltages As ldquoVlotaux+5Vrdquo at pin 5 and 7 are okay ldquoVT_supplyrdquo at pin 9 is missing Conclusion resistor 3449 and 3450 are defective

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds

How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

bull For a good understanding of the following circuit descriptions please use the block diagram in chapter 6 andor the electrical diagrams in chapter 7 Where necessary you will find a separate drawing for clarification
91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC

971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)
I2C protectionTo check whether all I2C ICs are functioning

Service Modes Error Codes and Fault FindingEN 10 L032L AA5
55 Error Codes
In case of non-intermittent faults clear the error buffer before you begin the repair These to ensure that old error codes are no longer present If possible check the entire contents of the error buffer In some situations an error code is only the result of another error code and not the actual cause (eg a fault in the protection detection circuitry can also lead to a protection)
Table 5-3 Error Code Table
56 The Blinking LED Procedure
Via this procedure you can make the contents of the error buffer visible via the front LED This is especially useful when there is no picture When the SDAM is entered the LED will blink the contents of the error-buffer bull n short blinks (n = 1 - 14)bull When all the error-codes are displayed the sequence
finishes with a LED blink of 3 sbull The sequence starts again
Example of error buffer 12 9 6 0 0 After entering SDAM bull 12 short blinks followed by a pause of 3 sbull 9 short blinks followed by a pause of 3 sbull 6 short blinks followed by a pause of 3 sbull 1 long blink of 3 s to finish the sequencebull the sequence starts again
57 Protections
If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode Blinking of the red LED at a frequency of 3 Hz indicates the protection mode In some error cases the microprocessor does not put the set in the protection mode The error codes of the error buffer can be read via the service menu (SDAM) the blinking LED procedure or via ComPair To get a quick diagnosis the chassis has one service modes implementedbull The Service Default Alignment Mode (SDAM) Start-up of
the set in a predefined way and adjustment of the set via a menu and with the help of test patterns
58 Repair Tips
Below some failure symptoms are given followed by a repair tipbull Set is dead and makes hiccupping sound ldquoMain
Supplyrdquo is available Hiccupping stops when de-soldering L5563 meaning that problem is in the ldquoMain Supplyrdquo line No output voltages at LOT no horizontal deflection Reason line transistor 7421 is defective
bull Set is dead and makes no sound Check power supply IC 7520 Result voltage at pins 2 6 7 9 and 11 are about 180 V and pin 14 is 0 V The reason why the voltage on these pins is so high is because the output driver (pin 11) has an open load That is why MOSFET 7521 is not able to switch Reason feedback resistor 3523 is defective Caution be careful measuring on the gate of 7521 circuitry is very high ohmic and can easily be damaged
bull Set is in hiccup mode and shuts down after 8 s Blinking LED (set in SDM mode) indicates error 5 As it is unlikely that the ldquoPORrdquo and ldquo+8V protectionrdquo happen at the same time measure the ldquo+8Vrdquo If this voltage is missing check transistor 7491 and 7496
bull Set is non-stop in hiccup mode Set is in over current mode check the secondary sensing (opto coupler 7515) and the ldquoMain Supplyrdquo voltage Signal ldquoStdby_conrdquo must be logic low under normal operation conditions and goes to high (33 V) under standby and fault conditions
bull Set turns on but without picture and sound The screen shows snow but OSD and other menus are okay Blinking LED procedure indicates error 11 so problem is expected in the tuner (pos 1000) Check presence of supply voltages As ldquoVlotaux+5Vrdquo at pin 5 and 7 are okay ldquoVT_supplyrdquo at pin 9 is missing Conclusion resistor 3449 and 3450 are defective

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)
How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)
How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

Note The Service Default Alignment Mode (SDAM) is described in the Service Modes Error Codes and Fault Finding section SDAM menu navigation is performed by using the MENU UP MENU DOWN MENU LEFT and MENU RIGHT keys of the remote control transmitter
81 General Alignment Conditions
Perform all electrical adjustments under the following conditionsbull AC voltage and frequency according to countrys
standardbull Connect the television set to the AC power via an isolation
transformerbull Allow the television set to warm up for approximately 20
minutesbull Measure the voltages and waveforms in relation to chassis
ground (with the exception of the voltages on the primary side of the power supply) Never use heatsinks as ground
bull Test probe Ri gt 10 M ohm Ci lt 25 pFbull Use an isolated trimmerscrewdriver to perform the
alignments

821 Vg2 Adjustment
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the WHITE TONE sub menu
3 Press the MENU LEFTRIGHT key to enter the WHITE TONE sub menu
4 In the WHITE TONE sub menu press the MENU UPDOWN keys to select NORMAL RED NORMAL GREEN or NORMAL BLUE
5 Use the MENU LEFTRIGHT keys to set the values of NORMAL RED NORMAL GREEN and NORMAL BLUE to 40
6 Press the MENU button twice to enter the normal user menu
7 In the normal user menu use the MENU UPDOWN keys to highlight the PICTURE sub menu (if necessary)
8 Press the MENU LEFTRIGHT keys to enter the PICTURE sub menu
9 Use the MENU UPDOWN keys to select CONTRAST Be sure to record the current value of CONTRAST
10 Use the MENU LEFTRIGHT keys to set the value of CONTRAST to 0
11 Use the MENU UPDOWN keys to select BRIGHTNESS Be sure to record the current value of BRIGHTNESS
12 Use the MENU LEFTRIGHT keys to set the value of BRIGHTNESS to minimum (OSD just visible in a dark room)
13 Press the MENU button twice to return to the top level SDAM menu
14 Press the OSDSTATUS button to hide the SDAM onscreen display (S indication remains visible) This to avoid interferences during the waveform measurements
15 Connect the RF output of a video pattern generator to the antenna input and input a black picture test pattern to the television set

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)
How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds

How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

bull For a good understanding of the following circuit descriptions please use the block diagram in chapter 6 andor the electrical diagrams in chapter 7 Where necessary you will find a separate drawing for clarification
91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC

971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)
I2C protectionTo check whether all I2C ICs are functioning

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)
How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)
How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard

How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

bull For a good understanding of the following circuit descriptions please use the block diagram in chapter 6 andor the electrical diagrams in chapter 7 Where necessary you will find a separate drawing for clarification
91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC

971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)
I2C protectionTo check whether all I2C ICs are functioning

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds

How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

bull For a good understanding of the following circuit descriptions please use the block diagram in chapter 6 andor the electrical diagrams in chapter 7 Where necessary you will find a separate drawing for clarification
91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC

971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)
I2C protectionTo check whether all I2C ICs are functioning

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)
How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

Note The Service Default Alignment Mode (SDAM) is described in the Service Modes Error Codes and Fault Finding section SDAM menu navigation is performed by using the MENU UP MENU DOWN MENU LEFT and MENU RIGHT keys of the remote control transmitter
81 General Alignment Conditions
Perform all electrical adjustments under the following conditionsbull AC voltage and frequency according to countrys
standardbull Connect the television set to the AC power via an isolation
transformerbull Allow the television set to warm up for approximately 20
minutesbull Measure the voltages and waveforms in relation to chassis
ground (with the exception of the voltages on the primary side of the power supply) Never use heatsinks as ground
bull Test probe Ri gt 10 M ohm Ci lt 25 pFbull Use an isolated trimmerscrewdriver to perform the
alignments

10 Use the MENU LEFTRIGHT keys to set the value of CONTRAST to 0
11 Use the MENU UPDOWN keys to select BRIGHTNESS Be sure to record the current value of BRIGHTNESS
12 Use the MENU LEFTRIGHT keys to set the value of BRIGHTNESS to minimum (OSD just visible in a dark room)
13 Press the MENU button twice to return to the top level SDAM menu
14 Press the OSDSTATUS button to hide the SDAM onscreen display (S indication remains visible) This to avoid interferences during the waveform measurements
15 Connect the RF output of a video pattern generator to the antenna input and input a black picture test pattern to the television set
16 Set the oscilloscope to 50 Vdiv and the time base to 02 milliseconds (external triggering on the positive vertical pulse with a 101 probe)
17 Ground the scope at the CRT panel and connect a 1001 probe to one of the cathodes of the picture tube socket (pin 7= Red pin 9= Green and pin 3= Blue see also schematic diagram B1) Measure the level of the black current measuring pulses These are the second line (Red) third line (Green) and fourth line (Blue) directly after the frame blanking (see figure Vcut-off) Remark This chassis is using a TDA93XX UOC series These use two different measuring pulses at each of the R G and B outputs The above-mentioned level applies to the pulse with the lowest level of each gun
18 Select the cathode with the highest VDC value for the alignment Adjust the Vcut-off of this gun with the SCREEN potentiometer (see figure Top view family board) on the LOT to the correct value (see table Vg2 alignment values)

The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)
How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)
I2C protectionTo check whether all I2C ICs are functioning

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard

How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

bull For a good understanding of the following circuit descriptions please use the block diagram in chapter 6 andor the electrical diagrams in chapter 7 Where necessary you will find a separate drawing for clarification
91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC

971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)
I2C protectionTo check whether all I2C ICs are functioning

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)
How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)
How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)
How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)
How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)
How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)
How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC

971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)
I2C protectionTo check whether all I2C ICs are functioning

13 Press the MENU button twice to return to the top level SDAM menu
14 Press the OSDSTATUS button to hide the SDAM onscreen display (S indication remains visible) This to avoid interferences during the waveform measurements
15 Connect the RF output of a video pattern generator to the antenna input and input a black picture test pattern to the television set
16 Set the oscilloscope to 50 Vdiv and the time base to 02 milliseconds (external triggering on the positive vertical pulse with a 101 probe)
17 Ground the scope at the CRT panel and connect a 1001 probe to one of the cathodes of the picture tube socket (pin 7= Red pin 9= Green and pin 3= Blue see also schematic diagram B1) Measure the level of the black current measuring pulses These are the second line (Red) third line (Green) and fourth line (Blue) directly after the frame blanking (see figure Vcut-off) Remark This chassis is using a TDA93XX UOC series These use two different measuring pulses at each of the R G and B outputs The above-mentioned level applies to the pulse with the lowest level of each gun
18 Select the cathode with the highest VDC value for the alignment Adjust the Vcut-off of this gun with the SCREEN potentiometer (see figure Top view family board) on the LOT to the correct value (see table Vg2 alignment values)
19 Press the OSDSTATUS button to display the SDAM onscreen display

83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)
How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable

The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)
I2C protectionTo check whether all I2C ICs are functioning

1 Connect the RF output of a video pattern generator to the antenna input
2 Input a circle or crosshatch test pattern to the television set3 Press the SMART PICTURE button on the remote control
transmitter repeatedly to choose NATURAL (or MOVIES) picture mode
4 Adjust the FOCUS potentiometer (see figure Top view family board) until the vertical lines near the left and right sides of the screen and near the horizontal center of the screen are at minimum width without visible haze
83 Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO
831 OPTIONS
Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary
How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value
1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu
3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu
4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7
5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)
6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made
press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings
8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)
How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they
enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain
value (see first column value between brackets in table below) When an option bit is disabled its value is 0
3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

bull For a good understanding of the following circuit descriptions please use the block diagram in chapter 6 andor the electrical diagrams in chapter 7 Where necessary you will find a separate drawing for clarification
91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

834 Geometry
IntroductionThe geometry alignment menu contains several items for correct picture geometry alignment
Figure 8-4 Geometry alignments
1 Connect the RF output of a video pattern generator to the antenna input
2 Input a crosshatch test pattern to the television set3 Set the amplitude of the video pattern generator to at least
1 mV and set the frequency to 47525 MHz (PALSECAM) or 6125 MHz (NTSC)
4 Press the SMART PICTURE button on the remote control transmitter repeatedly to choose PERSONAL or MOVIES picture mode
5 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)
6 Use the MENU UPDOWN keys to highlight the GEOMETRY sub menu
7 Press the MENU LEFTRIGHT keys to enter the GEOMETRY sub menu
8 Use the MENU UPDOWN keys to highlight either the HORIZONTAL sub menu or the VERTICAL sub menu
9 Press the MENU LEFTRIGHT keys to enter either the HORIZONTAL sub menu or the VERTICAL sub menu
10 Use the MENU UPDOWN keys to select items in the HORIZONTAL sub menu or the VERTICAL sub menu
11 Use the MENU LEFTRIGHT keys to adjust the values of items in the HORIZONTAL and VERTICAL sub menus
12 When all desired changes to the HORIZONTAL and VERTICAL sub menu values are made press the MENU button twice to return to the top level SDAM menu
13 To ensure the GEOMETRY settings are savedndash Turn the television set off by using the POWER
button on the remote control transmitter or the local keyboard
ndash Disconnect the television set from AC power for at least ten seconds
ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER
button on the remote control transmitter or the local keyboard
The following alignments can be performed in the GEOMETRY sub menu
Horizontal Alignmentsbull Horizontal Shift (HSH) Select Horizontal Shift to center the
picture on the screenbull Picture Width (PW) Aligns the width of the picture
Vertical Alignmentsbull Vertical slope (VSL) Aligns the picture so the proportions
are the same at the top and bottom of the screen This alignment must be performed first before all other vertical alignments Turning SBL on will assist in performing this alignment
bull Vertical Amplitude (VAM) Aligns the height of the picture (other vertical alignments are NOT compensated)
bull Vertical S-Correction (VSC) Aligns the vertical linearity so that the vertical intervals of the grid-patterns are the same over the entire height of the screen
bull Vertical Shift (VSH) Aligns the vertical center of the picture to the vertical center of the CRT After performing this alignment it may be necessary to perform the VAM alignment again
bull Service blanking (SBL) Turns the blanking of the lower half of the screen on or off (to be used in combination with the vertical slope alignment)
Methods of AdjustmentVertical Amplitude and Position1 Select SERVICE BLANKING (SBL) and set it to 1 The
lower half of the picture will be blanked2 Press the MENU UPDOWN buttons to select VERTICAL
SLOPE (VSL) 3 Align VSL to start the blanking exactly at the horizontal
white line at the center of the test circle (align the bottom of the screen so that castellations just disappear)
4 Press the MENU UPDOWN buttons to select SBL and set it back to 0 The full picture reappears
5 Select VERTICAL AMPLITUDE (VAM) and align the picture height to approximately 130 - 131 blocks (align the top of the screen so that castellations just disappear)
6 Select VERTICAL SHIFT (VSH) and align for vertical centering of the picture on the screen
7 Repeat the last two steps if necessary
Horizontal Phase1 Set PW to 0 2 Select Horizontal Shift (HSH) to center the picture on the
screen
Horizontal and Vertical Shift Offset for NTSC (TriNorma and PAL chassis) 1 Align the set for VSH and HSH (according to above
mentioned procedures) with a PAL system signal2 Change the signal to NTSC system and adjust
HORIZONTAL SHIFT OFFSET (H60) and VERTICAL SHIFT OFFSET (V60) to center the picture on the screen
3 Repeat if necessary

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)

94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)
I2C protectionTo check whether all I2C ICs are functioning

described in this chapter For the other circuit descriptions see the manual of the L012L AA
bull Figures can deviate slightly from the actual situation due to different set executions
bull For a good understanding of the following circuit descriptions please use the block diagram in chapter 6 andor the electrical diagrams in chapter 7 Where necessary you will find a separate drawing for clarification
91 Introduction
The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part
The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis
92 Source Selection
The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be
done entirely by the UOC and will only be able to select one external audio source
bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection
921 Switching Function for Stereo IO
Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC
922 Switching Function for Mono IO
For the Mono configuration only one input pin is available for the UOC
Video Source SelectionThe video switching is similar to the section above
Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC
93 Audio
This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing
931 Processing
This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)
932 Amplifier
The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output
Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9
The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)
I2C protectionTo check whether all I2C ICs are functioning

The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector
933 AVL (Automatic Volume Limiting)
The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below
Figure 9-1 AVL timing diagram
934 Mute
The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV
AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed
bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all
initialization processes are finishedbull When the set is going to STANDBY MUTE must be
activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier
mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC
TDA9853H3 Above conditions refers to both mono and stereo sets
94 Video
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder
95 Synchronization
Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized
with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information
96 Deflection
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)
97 Power Supply
For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable
971 Introduction
The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set
972 Derived Voltages
The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

98 Control
The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus
981 I2C-Bus
The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc
982 User Interface
The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)
983 IO Selection
For the control of the input and output selections there are three lines
STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets
STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low
SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines
984 Power Supply Control
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ
STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection
This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted
Figure 9-2 Block diagram of power supply interface with UOC
PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly
985 Protection Events
Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode
Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)
I2C protectionTo check whether all I2C ICs are functioning
