SAFETY PRECAUTIONS
Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by in theSchematic Diagram and Exploded View.It is essential that these special safety parts should be replaced with the same components as recommended in this manual to preventShock, Fire, or other Hazards. Do not modify the original design without permission of manufacturer.
General Guidance
An isolation Transformer should always be used during theservicing of a receiver whose chassis is not isolated from the ACpower line. Use a transformer of adequate power rating as thisprotects the technician from accidents resulting in personal injuryfrom electrical shocks.
It will also protect the receiver and it's components from beingdamaged by accidental shorts of the circuitry 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 Film Resistor,over 1W), keep the resistor 10mm away from PCB.
Keep wires away from high voltage or high temperature parts.
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., tobe sure the set is safe to operate without damage of electricalshock.
Leakage Current Cold Check(Antenna Cold Check)With the instrument AC plug removed from AC source, connect anelectrical jumper across the two AC plug prongs. Place the ACswitch in the on position, connect one lead of ohm-meter to the ACplug prongs tied together and touch other ohm-meter lead in turn toeach exposed metallic parts such as antenna terminals, phonejacks, 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 AC voltmeterwith 1000 ohms/volt or more sensitivity.Reverse plug the AC cord into the AC outlet and repeat AC voltagemeasurements for each exposed metallic part. Any voltagemeasured must not exceed 0.75 volt RMS which is corresponds to0.5mA.In case any measurement is out of the limits specified, there ispossibility of shock hazard and the set must be checked andrepaired before it is returned to the customer.

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 safety precautions onpage 3 of this publication, always follow the safety 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 incorrect polarityinstallation of electrolytic capacitors may result in anexplosion hazard.
2. Test high voltage only by measuring it with an appropriate highvoltage 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. Do not spray chemicals on or near this receiver or any of itsassemblies.
4. Unless specified otherwise in this service manual, cleanelectrical contacts only by applying the following mixture to thecontacts with a pipe cleaner, cotton-tipped stick or comparablenon-abrasive applicator; 10% (by volume) Acetone and 90% (byvolume) isopropyl alcohol (90%-99% strength)CAUTION: This is a flammable mixture.Unless specified otherwise in this service manual, lubrication ofcontacts in not required.
5. Do not defeat any plug/socket B+ voltage interlocks with whichreceivers covered by this service manual might be equipped.
6. Do not apply AC power to this instrument and/or any of itselectrical assemblies unless all solid-state device heat sinks arecorrectly installed.
7. Always connect the test receiver ground lead to the receiverchassis ground before connecting the test receiver positivelead.Always remove the test receiver ground lead last.
8. Use with this receiver only the test fixtures specified in thisservice manual.CAUTION: Do not connect the test fixture ground strap to anyheat sink in this receiver.
Electrostatically Sensitive (ES) DevicesSome semiconductor (solid-state) devices can be damaged easilyby static electricity. Such components commonly are calledElectrostatically Sensitive (ES) Devices. Examples of typical ESdevices are integrated circuits and some field-effect transistors andsemiconductor "chip" components. The following techniquesshould be used to help reduce the incidence of componentdamage caused by static by static electricity.1. Immediately before handling any semiconductor component or
semiconductor-equipped assembly, drain off any electrostaticcharge on your body by touching a known earth ground.Alternatively, obtain and wear a commercially availabledischarging wrist strap device, which should be removed toprevent potential shock reasons prior to applying power to the
unit under test.2. After removing an electrical assembly equipped with ES
devices, 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 unsolder ESdevices.
4. Use only an anti-static type solder removal device. Some solderremoval devices not classified as "anti-static" can generateelectrical charges sufficient to damage ES devices.
5. Do not use freon-propelled chemicals. These can generateelectrical charges sufficient to damage ES devices.
6. Do not remove a replacement 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, aluminum foilor comparable conductive material).
7. Immediately before removing the protective material from theleads of a replacement ES device, touch the protective materialto the chassis or circuit assembly into which the device will beinstalled.CAUTION: Be sure no power is applied to the chassis or circuit,and observe all other safety precautions.
8. Minimize bodily motions when handling unpackagedreplacement ES devices. (Otherwise harmless motion such asthe brushing together of your clothes fabric or the lifting of yourfoot from a carpeted floor can generate static electricitysufficient to damage an ES device.)
General Soldering Guidelines1. Use a grounded-tip, low-wattage soldering iron and appropriate
tip size and shape that will maintain tip temperature within therange or 500F to 600F.
2. Use an appropriate gauge of RMA resin-core solder composedof 60 parts tin/40 parts lead.
3. Keep the soldering iron tip clean and well tinned.4. Thoroughly clean the surfaces to be soldered. Use a mall wire-
bristle (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 the circuitboard 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.c. Quickly move the soldering iron tip to the junction of the
component lead and the printed circuit foil, and hold it thereonly 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 excess orsplashed 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 following techniqueshould be used to remove and replace the IC. When working withboards using the familiar round hole, use the standard techniqueas outlined in paragraphs 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 the soldermelts.
2. Draw away the melted solder with an anti-static suction-typesolder removal device (or with solder braid) before removing theIC.
Replacement1. Carefully insert the replacement IC in the circuit board.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 and crimp the "U" withlong nose pliers to insure metal to metal contact then soldereach connection.
Power Output, Transistor DeviceRemoval/Replacement1. Heat and remove all solder from around the transistor leads.2. Remove the heat sink 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 heat sink.
Diode Removal/Replacement1. Remove defective diode by clipping its leads as close as
possible to diode body.2. Bend the two remaining leads perpendicular 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 them and ifnecessary, 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 board toprevent 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. Thefollowing guidelines and procedures should be followed wheneverthis condition is encountered.
At IC ConnectionsTo repair a defective copper pattern at IC connections use thefollowing procedure to install a jumper wire on the copper patternside 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 absolutely necessary).
2. carefully scratch away the solder resist and acrylic coating (ifused) 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-away copperpattern and let it overlap the previously scraped end of the goodcopper pattern. Solder the overlapped area and clip off anyexcess jumper wire.
At Other ConnectionsUse the following technique to repair the defective copper patternat connections other than IC Pins. This technique involves theinstallation of a jumper wire on the component side of the circuitboard.
1. Remove the defective copper pattern with a sharp knife.Remove at least 1/4 inch of copper, to ensure that a hazardouscondition will not exist if the jumper wire opens.
2. Trace along the copper pattern from both sides of the patternbreak and locate the nearest component that is directlyconnected to the affected copper pattern.
3. Connect insulated 20-gauge jumper wire from the lead of thenearest component on one side of the pattern break to the leadof the nearest component on the other side.Carefully crimp and solder the connections.CAUTION: Be sure the insulated jumper wire is dressed so theit does not touch components or sharp edges.
