2. Safety and Maintenance Instructions, Warnings, and Notes
Index of this chapter:1. Safety Instructions for Repairs2. Maintenance Instructions3. Warnings4. Notes
2.1 Safety Instructions for Repairs
Safety regulations require that during a repair:• Due to the 'hot' parts of this chassis, the set must be
connected to the AC power via an isolation transformer.• Safety components, indicated by the symbol , should be
replaced by components identical to the original ones.• When replacing the CRT, safety goggles must be worn. Safety regulations require that after a repair, the set must be returned in its original condition. Pay particular attention to the following points:• General repair instruction: as a strict precaution, we advise
you to resolder the solder connections through which the horizontal deflection current is flowing, in particular:– all pins of the line output transformer (LOT)– fly-back capacitor(s)– S-correction capacitor(s)– line output transistor– pins of the connector with wires to the deflection coil– other components through which the deflection current
flows.Note: This resoldering 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 old.• Route the wire trees and EHT cable correctly and secure
them with the mounted cable clamps.• Check the insulation of the AC power cord for external
damage.• Check the strain relief of the AC power cord for proper
function, to prevent the cord from touching the CRT, hot components, or heat sinks.
• Check the electrical DC resistance between the AC plug and the secondary side (only for sets that have an isolated power supply). Do this as follows:1. Unplug the AC power cord and connect a wire between
the two pins of the AC plug.2. Turn on the main power switch (keep the AC power
cord unplugged!).3. Measure the resistance value between the pins of the
AC plug and the metal shielding of the tuner or the aerial connection of the set. The reading should be between 4.5 MOhm and 12 MOhm.
4. Switch the TV 'off' and remove the wire between the two pins of the AC plug.
• Check the cabinet for defects, to prevent the possibility of the customer touching any internal parts.
2.2 Maintenance Instructions
It is recommended to have a maintenance inspection carried out by qualified service personnel. The interval depends on the usage conditions:• When the set is used under normal circumstances, for
example in a living room, the recommended interval is three to five years.
• When the set is used in an environment with higher dust, grease or moisture levels, for example in a kitchen, the recommended interval is one year.
• The maintenance inspection includes the following actions:1. Perform the 'general repair instruction' noted above.2. Clean the power supply and deflection circuitry on the
chassis.
3. Clean the picture tube panel and the neck of the picture tube.
2.3 Warnings
• 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 Fig. 2-1, 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
• All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD ). Careless handling during repair can reduce life drastically. When repairing, make sure that 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 potential.
• Available ESD protection equipment:– Complete kit ESD3 (small tablemat, wristband,
connection box, extension cable, and ground cable) 4822 310 10671.
– Wristband tester 4822 344 13999.• Together with the deflection unit and any multi-pole unit,
flat square picture tubes form an integrated unit. The deflection and the multi-pole units are set optimally at the factory. Adjustment of this unit during repair is therefore not recommended.
• Be careful during measurements in the high voltage section and on the picture tube.
• Never replace modules or other components while the unit is switched 'on'.
• 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.
2.4 Notes
2.4.1 General
• Measure the voltages and waveforms with regard to the chassis (= tuner) ground (), or hot ground (), depending on the area of circuitry being tested.
• The voltages and waveforms shown in the diagrams are indicative. Measure them in the Service Default Mode (see “Service Modes, Error Codes, and Faultfinding” section) with a color bar signal and stereo sound (L: 3 kHz, R: 1 kHz unless stated otherwise) and picture carrier at 61.25 MHz (NTSC, channel 3).
• 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 standby (). These values are indicated by means of the appropriate symbols.
V
CL96532156_040.eps140501
Safety and Maintenance Instructions, Warnings, and Notes EN 5L03.1L AA 2.
• The picture tube panel has printed spark gaps. Each spark gap is connected between an electrode of the picture tube and the Aquadag coating.
• The semiconductors indicated in the circuit diagram and in the parts lists are completely interchangeable per position with the semiconductors in the unit, irrespective of the type indication on these semiconductors.
2.4.2 Schematic Notes
• All Resistor values are in ohms and the value multiplier is often used to indicate the decimal point location (e.g. 2K2 indicates 2.2 kOhm).
• Resistor values with no multiplier may be indicated with either an 'E' or an 'R' (e.g. 220E or 220R indicates 220 Ohm).
• All Capacitor values are expressed in Micro-Farads (µ = x10-6), Nano-Farads (n = x10-9), or Pico-Farads(p = x10-12).
• Capacitor values may also use the value multiplier as the decimal point indication (e.g. 2p2 indicates 2.2 pF).
• An 'asterisk' (*) indicates component usage varies. Refer to the diversity tables for the correct values.
• The correct component values are listed in the Electrical Replacement Parts List. Therefore, always check this list when there is any doubt.
2.4.3 Practical Service Precautions
• 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.
• Always respect voltages. While some may not be dangerous in themselves, they can cause unexpected reactions - 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.
• Before powering up the TV set with the back cover off (or on a test fixture), attach a clip lead to the CRT DAG ground and to a screwdriver blade that has a well insulated handle. After the TV is powered on and high voltage has developed, probe the anode lead with the blade, starting at the case of the High Voltage Transformer (flyback - IFT). Move the blade to within two inches of the connector of the CRT. If there is an arc, you found it the easy way, without getting a shock! If there is an arc to the screwdriver blade, replace the part which is causing the problem; the High Voltage Transformer or the lead (if it is removable).

Service Modes, Error Codes, and Fault FindingEN 16 L03.1L AA5.
5. Service Modes, Error Codes, and Fault Finding
Index:1. Test points.2. Service Modes.3. Problems and Solving Tips.4. ComPair5. The Blinking LED Procedure.6. Protections.7. Repair Tips.
5.1 Test Points
This chassis is equipped with test points in the service printing. In the schematics test points are identified with a rectangle box around Fxxx or Ixxx.
Table 5-1 Test Point Overview
Perform measurements under the following conditions:• Service Default Alignment Mode.• Video: color bar signal.• Audio: 3 kHz left, 1 kHz right.
5.2 Service Modes
Service Default Alignment Mode (SDAM) offers several features for the service technician. There is also the option of using ComPair, a hardware interface between a computer (see requirements) and the TV chassis. It offers the ability of structured trouble shooting, error code reading and software version readout for all chassis. Requirements: To run ComPair on a computer (laptop or desktop) requires, as a minimum, a 486 processor, Windows 3.1 and a CD-ROM drive. A Pentium Processor and Windows 95/98 are however preferred (see also paragraph 5.4).
Table 5-2 SW Cluster
5.2.1 Service Default Alignment Mode (SDAM)
Purpose• To change option settings.• To create a predefined setting to get the same
measurement results as given in this manual.• To display / clear the error code buffer. • To override SW protections.• To perform alignments.• To start the blinking LED procedure.
Specifications• Tuning frequency: 61.25 MHz (channel 3) for NTSC-sets
(LATAM).• Color system: PAL-M for LATAM BI/TRI/FOUR-NORMA.• All picture settings at 50 % (brightness, color contrast,
hue).• Bass, treble and balance at 50 %; volume at 25 %. • All service-unfriendly modes (if present) are disabled, like:
– (Sleep) timer, – Child/parental lock, – Blue mute, – Hotel/hospitality mode– Auto switch-off (when no “IDENT” video signal is
received for 15 minutes),– Skip / blank of non-favorite presets / channels,– Auto store of personal presets,– Auto user menu time-out.

How to activate SDAMUse one of the following methods:• Use a standard customer RC-transmitter and key in the
code 062596 directly followed by the “M” (menu) button or• Temporarily connect jumper wire 9257 to pin 4 of 7200 on
the mono carrier (see Fig. 8-1) and apply AC power. Then press the power button (remove the connection after start-up).Caution: Activating SDAM by temporarily connecting jumper wire 9257 to pin 4 of 7200 will override the +8V-protection. Do this only for a short period. When doing this, the service-technician must know exactly what he is doing, as it could lead to damaging the set.

5.4 ComPair
5.4.1 Introduction
ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products. ComPair is a further development on the European DST (Dealer Service Tool), which allows faster and more accurate diagnostics. ComPair has three big advantages:• 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.
• 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.
• ComPair speeds up the repair time since it can automatically communicate with the chassis (when the
Service Modes, Error Codes, and Fault FindingEN 18 L03.1L AA5.
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.
5.4.2 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 case of the L03 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 also figure 8-1 suffix D). The ComPair faultfinding program is able to determine the problem of the defective television. ComPair can gather diagnostic information in two ways:• Automatically (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.
• 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 extend. When this is not the case, ComPair will guide you through the faultfinding tree by asking you questions (e.g. Does the screen give a picture? Click on the correct answer: YES / NO) and showing you examples (e.g. Measure test-point F001 and click on the correct oscillogram you see on the oscilloscope). You can answer by clicking on a link (e.g. 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. Beside fault finding, ComPair provides some additional features like:• Up- or downloading of pre-sets.• Managing of pre-set lists.• 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 (Schematic/Panel) at the Mono-carrier. – Click on the 'Panel' hyperlink to automatically show the
PWB with a highlighted capacitor C2568. – Click on the 'Schematic' hyperlink to automatically
show the position of the highlighted capacitor.
5.4.3 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 “PC”) of the ComPair interface.
3. Connect the AC power adapter to the supply connector (marked with “POWER 9V DC”) on the ComPair interface.
4. Switch the ComPair interface OFF.5. 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 “I2C”) and the ComPair connector on the mono carrier (see figure 8-1 suffix D).
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 “introduction” chapter.

• ComPair interface cable: 3122 785 90004.
5.4.5 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.
5.4.6 How To Read The Error Buffer
You can read out the error buffer in 3 ways:• On screen via the SDAM (only if you have a picture).
Examples:– ERROR: 0 0 0 0 0: No errors detected– ERROR: 6 0 0 0 0: Error code 6 is the last and only
detected error– ERROR: 9 6 0 0 0: Error code 6 was first detected and
error code 9 is the last detected (newest) error• Via the blinking LED procedure (when you have no
picture). See next paragraph.• Via ComPair.
5.4.7 How To Clear The Error Buffer
The error code buffer is cleared in the following cases:• By activation of the CLEAR command in the SDAM menu:• If the content of the error buffer has not changed for 50
hours, it resets automatically.
Note:When leaving SDAM by disconnecting the set from AC power, the error buffer is not reset.

Service Modes, Error Codes, and Fault Finding EN 19L03.1L AA 5.
5.4.8 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. It is wise to write down the errors of the error buffer before you clear it.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 (e.g., a fault in the protection detection circuitry can also lead to a protection).
Table 5-3 Error Code Table
5.5 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 activated, the LED will blink the contents of the error-buffer. • n short blinks (n = 1 - 14),• When all the error-codes are displayed, the sequence
finishes with a LED blink of 3 s,• The sequence starts again. Example of error buffer: 12 9 6 0 0 After activating SDAM: • 12 short blinks followed by a pause of 3 s,• 9 short blinks followed by a pause of 3 s,• 6 short blinks followed by a pause of 3 s,• 1 long blink of 3 s to finish the sequence,• the sequence starts again.
5.6 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 mode implemented:• 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.
5.7 Repair Tips
Below some failure symptoms are given, followed by a repair tip.
• Set is dead and makes hiccupping sound. “MainSupply” is available. Hiccupping stops when de-soldering L5563, meaning that problem is in the “MainSupply” line. No output voltages at LOT, no horizontal deflection. Reason: line transistor 7421 is defective.
• 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!
• Set is in hiccup mode and shuts down after 8 s. Blinking LED (set in SDAM mode) indicates error 5. As it is unlikely that the “POR” and “+8V protection” happen at the same time, measure the “+8V”. If this voltage is missing, check transistor 7491 & 7496.
• Set is non-stop in hiccup mode. Set is in over current mode; check the secondary sensing (opto coupler 7515) and the “MainSupply” voltage. Signal “Stdby_con” must be logic low under normal operation conditions and goes to high (3.3 V) under standby and fault conditions.
• 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 “Vlotaux+5V” at pin 5 and 7 are okay, “VT_supply” at pin 9 is missing. Conclusion: resistors 3449 & 3450 are defective

8. Electrical Alignments
Index of this chapter:1. General Alignment Conditions2. Hardware Alignments3. Software Alignments and Settings 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.
8.1 General Alignment Conditions
Perform all electrical adjustments under the following conditions:• AC voltage and frequency: according to country’s
standard.• Connect the television set to the AC power via an isolation
transformer.• Allow the television set to warm up for approximately 20
minutes.• 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.
• Test probe: Ri > 10 M ohm; Ci < 2.5 pF.• Use an isolated trimmer/screwdriver to perform the
alignments.

14. Press the OSD/STATUS 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 V/div and the time base to 0.2 milliseconds (external triggering on the positive vertical pulse with a 10:1 probe).
17. Ground the scope at the CRT panel and connect a 100:1 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 "V_cut-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 V_dc value for the alignment. Adjust the V_cut-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 OSD/STATUS button to display the SDAM onscreen display.

8.3 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" section.The following alignments are explained:1. OPTIONS2. TUNER3. WHITE TONE4. GEOMETRY5. AUDIO
8.3.1 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 UP/DOWN 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 UP/DOWN 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 UP/DOWN 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 '255'.7. 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 effect:– Turn the television set 'off' by using the 'POWER'
button on the remote control transmitter or the local keyboard.
– Disconnect the television set from AC power for at least ten seconds.
– Reconnect the television set to AC power. – 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 way:1. 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.

9.1 Introduction
The "L03"' chassis is a global TV chassis for the model year 2003 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 processing. The standard architecture consists of a Main panel (called "family board"), a Picture Tube panel, a Side I/O panel, and a Top Control panel. The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part.
Figure 9-1 Top view family board
The functions for video processing, microprocessor (P), and CC/Teletext (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.
Figure 9-2 Bottom view family board
The L03 can be divided into two basic systems, i.e. 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.
9.2 Source Selection
The Source Select is divided mainly into two types, the "Mono Source Select" and the "Stereo Source Select".• 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.
• 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.
9.2.1 Switching Function for Stereo I/O
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).
Audio Source SelectionThe AN5829 (BTSC decoder) device does the external stereo audio source selection. A maximum of three audio input sources can be selected. AV1 or FRONT is selected by the mechanical switch in the front cinch connector.

The selected external audio source is then fed to the AN5829 AUX1 input (pins 2 and 3). The AV2 is fed directly to AN5829 via AUX2 (pins 23 and 24). Then via I2C, the AN5829 IC source selection can be done.
9.2.2 Switching Function for Mono I/O
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.
9.3 Audio
This chassis is targeted for the LATAM 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 AN5829S is the BTSC audio signal decoder and AN5891K is the audio processing IC.
9.3.1 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, and/or 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 (AN7522/23). The selected audio output from IC7841 (AN5829) is fed to pins 3 and 22 of IC7821 (AN5891) for audio processing functions, such as Treble, Bass, Volume, Balance, and Surround sound functions. L_out and R_out are then available on pins 12 and 15. IC7821 is also I2C controllable (pins 13 and 14). An AVL function is also available in this IC, and can be used for sets using this IC. In this case, the AVL function of the AN5829 is disabled. Subwoofer output (optional) is available on pin 20.
9.3.2 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 send to the speaker / headphone output connector.
9.3.3 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 resume to the previous state ("on/off") as shown in the timing diagram below.
The "Stereo AVL" function operates via the AGC control of IC AN5829S. During channel change and source selection, the AGC function is to be switched "off" and then can resume to the previous state ("on/off") as shown in timing diagram below.
Figure 9-3 AVL timing diagram
9.3.4 Mute
The TV set must mute:• Whenever a "User Mute" is activated.• 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.
• Whenever there is a loss in the signal.• During cold or warm start, MUTE must be activated until all
initialization processes are finished.• When the set is going to STANDBY, MUTE must be
activated first before any other activities. Note: 1. MUTE mentioned above applies for the audio amplifier
mute (= PWM volume control mute).2. The first condition does not apply for the UOC, IC
AN5891K, or IC AN5829S.3. Above conditions refers to both mono and stereo sets.
9.4 Video
For a detailed circuit description of this part, we refer to the L01.2L AA manual (see the beginning of this chapter for the ordering codes). Please note that there can be minor differences in the text (e.g. 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 Caption/TXT decoder.
9.5 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 OSD/TXT circuit for synchronization of the On Screen Display and Teletext (CC) information.
9.6 Deflection
For a detailed circuit description of this part, we refer to the L01.2L AA manual (see the beginning of this chapter for the ordering codes). Please note that there can be minor differences in the text (e.g. 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 East/West 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).
9.7 Power Supply
For a detailed circuit description of this part, we refer to the L01.2L AA manual (see the beginning of this chapter for the ordering codes). Please note that there can be minor differences in the text (e.g. other item numbers), but the described circuit principle is comparable.
9.7.1 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 enhanced.The 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 goes to the set.
9.7.2 Derived Voltages
The voltages supplied by the secondary windings of T5520 are:• "MainSupply" for the horizontal output.• "V_aux/V_audio" for the audio circuit.• An optional "DVD_Supply" 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.
9.8 Control
The microprocessor part of the UOC has the complete control and CC/Teletext processing on board. The User menu's and Service Default / Alignment Mode's are generated by the P. Communication to other ICs is done via the I2C-bus.
9.8.1 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.
9.8.2 User Interface
The chassis uses a remote control with RC5 protocol. The incoming signal is connected to pin 67 of the UOC.The keyboard, connected to UOC pin 8, can also control the set. Button recognition is done via a voltage divider.The 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 (e.g., responding to the remote control, normal operation (USA only) or fault condition)
9.8.3 I/O 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 LATAM/NAFTA 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 Y/C or CVBS source is present. The presence of an external Y/C 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.
9.8.4 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 3.3 V and 8 V. The 3.3 V is derived from the "V_aux/V_audio" voltage via a 3V3 stabilizer (7493). The 8 V is derived from the 33V tuner voltage via TS7491 and TS7496.Two 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" (3.3 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.

Circuit Descriptions, List of Abbreviations, and IC Data SheetsEN 56 L03.1L AA9.
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.
9.8.5 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 monitored:• SUP (Supply voltage indication)• XPR (X-ray protection)• EVG (Enable Vertical Guard)• NDF (Output Vertical Guard)• BCF (Black Current Failure)
I2C protectionTo check whether all I2C IC's are functioning.
