SAFETY PRECAUTIONS

Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by inthe Schematic Diagram and Replacement Parts List. It is essential that these special safety parts should be replaced with the same components as recommended in this manual toprevent X-RADIATION, Shock, Fire, or other Hazards. Do not modify the original design without permission of manufacturer.

General Guidance

An lsolation Transformer should always be used duringthe servicing of a receiver whose chassis is not isolated fromthe AC power line. Use a transformer of adequate power ratingas this protects the technician from accidents resulting inpersonal injury from electrical shocks.

It will also protect the receiver and its components from beingdamaged by accidental shorts of the circuitary that may beinadvertently introduced during the service operation.

If any fuse (or Fusible Resistor) in this TV receiver is blown,replace it with the specified.

When replacing a high wattage resistor (Oxide Metal FilmResistor, over 1W), keep the resistor 10mm away from PCB.

Keep wires away from high voltage or high temperature parts.

Due to high vacuum and large surface area of picture tube,extreme care should be used in handling the Picture Tube.Do not lift the Picture tube by its Neck.

X-RAY Radiation

Warning:

To determine the presence of high voltage, use an accuratehigh impedance HV meter.

Adjust brightness, color, contrast controls to minimum. Measure the high voltage. The meter reading should indicate 23.5 1.5KV: 14-19 inch, 26 1.5KV: 19-21 inch,29.0 1.5KV: 25-29 inch, 30.0 1.5KV: 32 inchIf the meter indication is out of tolerance, immediate serviceand correction is required to prevent the possibility ofpremature component failure.

Before returning the receiver to the customer,

always perform an AC leakage current check on the exposedmetallic parts of the cabinet, such as antennas, terminals, etc.,to be sure the set is safe to operate without damage ofelectrical shock.

Leakage Current Cold Check(Antenna Cold Check)With the instrument AC plug removed from AC source,connect an electrical jumper across the two AC plug prongs.Place the AC switch in the on positioin, connect one lead ofohm-meter to the AC plug prongs tied together and touch otherohm-meter lead in turn to each exposed metallic parts such asantenna terminals, phone jacks, etc. If the exposed metallic part has a return path to the chassis, themeasured resistance should be between 1M and 5.2M. When the exposed metal has no return path to the chassis thereading must be infinite.An other abnormality exists that must be corrected before thereceiver is returned to the customer.

Leakage Current Hot Check (See below Figure) Plug the AC cord directly into the AC outlet.Do not use a line Isolation Transformer during this check. Connect 1.5K/10watt resistor in parallel with a 0.15uF capacitorbetween a known good earth ground (Water Pipe, Conduit, etc.)and the exposed metallic parts.Measure the AC voltage across the resistor using ACvoltmeter with 1000 ohms/volt or more sensitivity.Reverse plug the AC cord into the AC outlet and repeat ACvoltage measurements for each esposed metallic part. Anyvoltage measured must not exceed 0.75 volt RMS which iscorresponds to 0.5mA.In case any measurement is out of the limits sepcified, there ispossibility of shock hazard and the set must be checked andrepaired before it is returned to the customer.

Leakage Current Hot Check circuit

The source of X-RAY RADIATION in this TV receiver is theHigh Voltage Section and the Picture Tube.For continued X-RAY RADIATION protection, thereplacement tube must be the same type tube as specified inthe Replacement Parts List.

CAUTION: Before servicing receivers covered by this servicemanual and its supplements and addenda, read and follow theSAFETY PRECAUTIONS on page 3 of this publication.NOTE: If unforeseen circumstances create conflict between thefollowing servicing precautions and any of the safetyprecautions on page 3 of this publication, always follow thesafety precautions. Remember: Safety First.

General Servicing Precautions1. Always unplug the receiver AC power cord from the AC

power source before;a. Removing or reinstalling any component, circuit board

module or any other receiver assembly.b. Disconnecting or reconnecting any receiver electrical plug

or other electrical connection.c. Connecting a test substitute in parallel with an electrolytic

capacitor in the receiver.CAUTION: A wrong part substitution or incorrectpolarity installation of electrolytic capacitors may resultin an explosion hazard.

d. Discharging the picture tube anode.2. Test high voltage only by measuring it with an appropriate

high voltage meter or other voltage measuring device (DVM,FETVOM, etc) equipped with a suitable high voltage probe.Do not test high voltage by "drawing an arc".

3. Discharge the picture tube anode only by (a) first connectingone end of an insulated clip lead to the degaussing or kineaquadag grounding system shield at the point where thepicture tube socket ground lead is connected, and then (b)touch the other end of the insulated clip lead to the picturetube anode button, using an insulating handle to avoidpersonal contact with high voltage.

4. Do not spray chemicals on or near this receiver or any of itsassemblies.

5. Unless specified otherwise in this service manual, cleanelectrical contacts only by applying the following mixture tothe contacts with a pipe cleaner, cotton-tipped stick orcomparable nonabrasive applicator; 10% (by volume)Acetone and 90% (by volume) isopropyl alcohol (90%-99%strength)CAUTION: This is a flammable mixture.Unless specified otherwise in this service manual, lubricationof contacts in not required.

6. Do not defeat any plug/socket B+ voltage interlocks withwhich receivers covered by this service manual might beequipped.

7. Do not apply AC power to this instrument and/or any of itselectrical assemblies unless all solid-state device heat sinksare correctly installed.

8. Always connect the test receiver ground lead to thereceiver chassis ground before connecting the test receiverpositive lead.Always remove the test receiver ground lead last.

9. Use with this receiver only the test fixtures specified in thisservice manual.CAUTION: Do not connect the test fixture ground strap toany heatsink in this receiver.

Electrostatically Sensitive (ES) DevicesSome semiconductor (solid state) devices can be damagedeasily by static electricity. Such components commonly arecalled Electrostatically Sensitive (ES) Devices. Examples oftypical ES devices are integrated circuits and some fieldeffect

transistors and semicounductor "chip" components. Thefollowing techniques should be used to help reduce theincidence of component damage caused by static by staticelectricity.1. Immediately before handling any semiconductor component

or semiconductor-equipped assembly, drain off anyelectostatic charge on your body by touching a known earthground. Alternatively, obtain and wear a commerciallyavailable discharging wrist strap device, which should beremoved to prevent potential shock reasons prior toapplying power to the unit under test.

2. After removing an electrical assembly equipped with ESdevices, place the assembly on a conductive surface such asaluminum foil, to prevent electrostatic charge buildup orexposure of the assembly.

3. Use only a grounded-tip soldering iron to solder or unsolderES devices.

4. Use only an anti-static type solder removal device. Somesolder removal devices not classified as "anti-static" cangenerate electrical charges sufficent to demage ES devices.

5. Do not use freon-propelled chemicals. These can generateelectrical charges sufficient to damage ES devices.

6. Do not remove a repalcement ES device from its protectivepackage until immediately before you are ready to install it.(Most replacement ES devices are packaged with leadselectrically shorted together by conductive foam, aluminumfoil or comparable conductive material).

7. Immediately before removing the protective material fromthe ieads of a replacement ES device, touch the protectivematerial to the chassis or circuit assembly into which thedevice will be installed.CAUTION:Be sure no power is applied to the chassis orcircuit, and observe all other safety precautions.

8. Minimize bodily motions when handling unpackagedreplacement ES devices. (Otherwise harmless motion suchas the bruching together of your clothes fabric or the liftingof your foot from a carpeted floor can generate staticelectricity sufficient to damage an ES device.)

General Soldering Guidelines1. Use a grounded-tip, low-wattage soldering iron and

appropriate tip size and shape that wil l maintan tiptemperature within the range or 500F to 600F.

2. Use an appropriate gauge of RMA resin-core soldercomposed of 60 parts tin/40 parts lead.

3. Keep the soldering iron tip clean and well tinned.4. Thorohly clean the surfaces to be soldered. Use a mall

wirebristle (0.5 inch, or 1.25cm) brush with a metal handle.Do not use freon-propelled spray-on cleaners.

5. Use the following unsoldering techniquea. Allow the soldering iron tip to reach normal temperature.

(500F to 600F)b. Heat the component lead until the solder melts.c. Quickly draw the melted solder with an anti-static,

suction-type solder removal device or with solder braid.CAUTION: Work quickly to avoid overheating thecircuiboard printed foil.

6. Use the following soldering technique.a. Allow the soldering iron tip to reach a normal

temperature (500F to 600F)b. First, hold the soldering iron tip and solder the strand

against the component lead until the solder melts.

SERVICING PRECAUTIONS

c. Qulckly move the soldering iron tip to the junction of thecomponent lead and the printed circuit foil, and hold itthere only until the solder flows onto and around both thecomponent lead and the foil.CAUTION: Work quickly to avoid overheating the circuitboard printed foil.

d. Closely inspect the solder area and remove any excessor splashed solder with a small wire-bristle brush.

IC Remove/ReplacementSome chassis circuit boards have slotted holes (oblong) throughwhich the IC leads are inserted and then bent flat against thecircuit foil. When holes are the slotted type, the followingtechnique should be used to remove and replace the IC. Whenworking with boards using the familiar round hole, use thestandard technique as outlined in parapraphs 5 and 6 above.

Removal1. Desolder and straighten each IC lead in one operation by

gently prying up on the lead with the soldering iron tip as thesolder melts.

2. Draw away the melted solder with an anti-static suction-type solder removal device (or with solder braid) beforeremoving the IC.

Replacement1. Carefully insert the replacement IC in the circuit boare.2. Carefully bend each IC lead against the circuit foil pad and

solder it.3. Clean the soldered areas with a small wire-bristle brush.

(It is not necessary to reapply acrylic coating to the areas).

"Small-Signal" Discrete TransistorRemoval/Replacement1. Remove the defective transistor by clipping its leads as

close as possible to the component body.2. Bend into a "U" shape the end of each of three leads

remaining on the circuit board.3. Bend into a "U" shape the replacement transistor leads.4. Connect the replacement transistor leads to the

corresponding leads extending from the circuit board andcrimp the "U" with long nose pliers to insure metal to metalcontact then solder each connection.

Power Output, Transistor DeviceRemoval/Replacement1. Heat and remove all solder from around the transistor leads.2. Remove the heatsink mounting screw (if so equipped).3. Carefully remove the transistor from the heat sink of the

circuit board.4. Insert new transistor in the circuit board.5. Solder each transistor lead, and clip off excess lead.6. Replace heatsink.

Diode Removal/Replacement1. Remove defective diode by clipping its leads as close as

possible to diode body.2. Bend the two remaining leads perpendicula y to the circuit

board.3. Observing diode polarity, wrap each lead of the new diode

around the corresponding lead on the circuit board.4. Securely crimp each connection and solder it.5. Inspect (on the circuit board copper side) the solder joints of

the two "original" leads. If they are not shiny, reheat themand if necessary, apply additional solder.

Fuse and Conventional ResistorRemoval/Replacement1. Clip each fuse or resistor lead at top of the circuit board

hollow stake.2. Securely crimp the leads of replacement component around

notch at stake top.3. Solder the connections.

CAUTION: Maintain original spacing between the replacedcomponent and adjacent components and the circuit boardto prevent excessive component temperatures.

Circuit Board Foil RepairExcessive heat applied to the copper foil of any printed circuitboard will weaken the adhesive that bonds the foil to the circuitboard causing the foil to separate from or "lift-off" the board.The following guidelines and procedures should be followedwhenever this condition is encountered.

At IC ConnectionsTo repair a defective copper pattern at IC connections use thefollowing procedure to install a jumper wire on the copperpattern side of the circuit board. (Use this technique only on ICconnections).

1. Carefully remove the damaged copper pattern with a sharpknife. (Remove only as much copper as absolutelynecessary).

2. carefully scratch away the solder resist and acrylic coating(if used) from the end of the remaining copper pattern.

3. Bend a small "U" in one end of a small gauge jumper wire andcarefully crimp it around the IC pin. Solder the IC connection.

4. Route the jumper wire along the path of the out-awaycopper pattern and let it overlap the previously scraped endof the good copper pattern. Solder the overlapped area andclip off any excess jumper wire.

At Other ConnectionsUse the following technique to repair the defective copperpattern at connections other than IC Pins. This techniqueinvoloves the installation of a jumper wire on the componentside of the circuit board.

1. Remove the defective copper pattern with a sharp knife.Remove at least 1/4 inch of copper, to ensure that ahazardous condition will not exist if the jumper wire opens.

2. Trace along the copper pattern from both sides of thepattern break and locate the nearest component that isdirectly connected to the affected copper pattern.

3. Connect insulated 20-gauge jumper wire from the lead ofthe nearest component on one side of the pattern break tothe lead of the nearest component on the other side.Carefully crimp and solder the connections.CAUTION: Be sure the insulated jumper wire is dressed sothe it does not touch components or sharp edges.

room) and pay attention not to touch the lens duringadjustment.

5) Screen the optional two lens with a cover so that the singlecolor is appeared on the screen.

6) When turn the light the lens at front, chromatic aberrationwhich appeared in bright line of cross-Hatch signal changedas below.

2. G-lens Adjustment1) Turn the lens until the chromatic aberration changed Blue to

Red point.2) Viewing the all screen, in no case of the chromatic aberration

appeared slimly within 3.5 cross-Hatch of the picture center. Atthis time, in case that the red chromatic aberration's bright lineisn't equal, adjust G-lens so that the red chromatic aberration isappeared more than previous time.

3) Switching the signal to 13CH and operate adjustmentminutely.

4) Adjust G-focus control volume of focus pack so that theexternal big circle's part appeared cleary.

5) Adjust accurately by repeat the upper control.6) Especially, noting to the G-light because it influenced on

picture's function.

3. R-lens Adjustment1) Turn the lens until the chromatic aberration changed orange

to scarlet. 2) Adjust the chromatic aberration so that it located center

correctly. 3) Switching the signal to 13CH and adjust it as same method

of G-lens.

4) Adjust as same method of G-lens with Red focus controlvolume of focus pack.

4. B- lens Adjustment

1) Turn the lens until the chromatic aberration changed purpleto green which of 3.5 Cross-Hatch part from picture's centertoward left.

2) Adjust the chromatic aberration become center of purple andgreen.

Note) After adjustment Red,Green & Blue lens, remove lenscover and receive Cross-Hatch pattern and check the overallfocus. If need, repeat above.

O Convergence Adjustment1. Preliminary steps

1) This adjustment should be performed after raster slant,raster position, horizontal and vertical adjustment.

2) This adjustment should be performed after warming up 60minutes.
