SAFETY PRECAUTIONS  
IMPORTANT SAFETY NOTICE  
Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by  
Schematic Diagram and Exploded View.  
in the  
It is essential that these special safety parts should be replaced with the same components as recommended in this manual to prevent  
Shock, Fire, or other Hazards.  
Do not modify the original design without permission of manufacturer.  
Leakage Current Hot Check (See below Figure)  
Plug the AC cord directly into the AC outlet.  
General Guidance  
An isolation Transformer should always be used during the  
servicing of a receiver whose chassis is not isolated from the AC  
power line. Use a transformer of adequate power rating as this  
protects the technician from accidents resulting in personal injury  
from electrical shocks.  
Do not use a line Isolation Transformer during this check.  
Connect 1.5 K / 10 watt resistor in parallel with a 0.15 uF capacitor  
between a known good earth ground (Water Pipe, Conduit, etc.)  
and the exposed metallic parts.  
Measure the AC voltage across the resistor using AC voltmeter  
with 1000 ohms/volt or more sensitivity.  
Reverse plug the AC cord into the AC outlet and repeat AC voltage  
measurements for each exposed metallic part. Any voltage  
measured must not exceed 0.75 volt RMS which is corresponds to  
0.5 mA.  
In case any measurement is out of the limits specified, there is  
possibility of shock hazard and the set must be checked and  
repaired before it is returned to the customer.  
It will also protect the receiver and it's components from being  
damaged by accidental shorts of the circuitry that may be  
inadvertently 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 1 W), keep the resistor 10 mm away from PCB.  
Leakage Current Hot Check circuit  
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 exposed  
metallic parts of the cabinet, such as antennas, terminals, etc., to  
be sure the set is safe to operate without damage of electrical  
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 position, connect one lead of ohm-meter to the AC  
plug prongs tied together and touch other ohm-meter lead in turn to  
each exposed metallic parts such as antenna terminals, phone  
jacks, etc.  
If the exposed metallic part has a return path to the chassis, the  
measured resistance should be between 1 MΩ and 5.2 MΩ.  
When the exposed metal has no return path to the chassis the  
reading must be infinite.  
An other abnormality exists that must be corrected before the  
receiver is returned to the customer.

SERVICING PRECAUTIONS  
CAUTION: Before servicing receivers covered by this service  
2. After removing an electrical assembly equipped with ES  
devices, place the assembly on a conductive surface such as  
aluminum foil, to prevent electrostatic charge buildup or expo-  
sure of the assembly.  
3. Use only a grounded-tip soldering iron to solder or unsolder  
ES devices.  
4. Use only an anti-static type solder removal device. Some sol-  
der removal devices not classified as “anti-static” can generate  
electrical charges sufficient to damage ES devices.  
5. Do not use freon-propelled chemicals. These can generate  
electrical charges sufficient to damage ES devices.  
6. Do not remove a replacement ES device from its protective  
package until immediately before you are ready to install it.  
(Most replacement ES devices are packaged with leads elec-  
trically shorted together by conductive foam, aluminum foil or  
comparable conductive material).  
manual and its supplements and addenda, read and follow the  
SAFETY PRECAUTIONS on page 3 of this publication.  
NOTE: If unforeseen circumstances create conflict between the  
following servicing precautions and any of the safety precautions  
on page 3 of this publication, always follow the safety precau-  
tions. Remember: Safety First.  
General Servicing Precautions  
1. 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 polarity  
installation of electrolytic capacitors may result in an explo-  
sion hazard.  
7. Immediately before removing the protective material from the  
leads of a replacement ES device, touch the protective mate-  
rial to the chassis or circuit assembly into which the device will  
be installed.  
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. Do not spray chemicals on or near this receiver or any of its  
assemblies.  
4. Unless specified otherwise in this service manual, clean  
electrical contacts only by applying the following mixture to the  
contacts with a pipe cleaner, cotton-tipped stick or comparable  
non-abrasive applicator; 10 % (by volume) Acetone and 90 %  
(by volume) isopropyl alcohol (90 % - 99 % strength)  
CAUTION: This is a flammable mixture.  
CAUTION: Be sure no power is applied to the chassis or cir-  
cuit, and observe all other safety precautions.  
8. Minimize bodily motions when handling unpackaged replace-  
ment ES devices. (Otherwise harmless motion such as the  
brushing together of your clothes fabric or the lifting of your  
foot from a carpeted floor can generate static electricity suf-  
ficient to damage an ES device.)  
General Soldering Guidelines  
1. Use a grounded-tip, low-wattage soldering iron and appropri-  
ate tip size and shape that will maintain tip temperature within  
the range or 500 °F to 600 °F.  
Unless specified otherwise in this service manual, lubrication  
of contacts in not required.  
2. Use an appropriate gauge of RMA resin-core solder composed  
of 60 parts tin/40 parts lead.  
5. Do not defeat any plug/socket B+ voltage interlocks with which  
receivers covered by this service manual might be equipped.  
6. Do not apply AC power to this instrument and/or any of its  
electrical assemblies unless all solid-state device heat sinks  
are correctly installed.  
7. Always connect the test receiver ground lead to the receiver  
chassis ground before connecting the test receiver positive  
lead.  
Always remove the test receiver ground lead last.  
8. Use with this receiver only the test fixtures specified in this  
service manual.  
CAUTION: Do not connect the test fixture ground strap to any  
heat sink in this receiver.  
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 1.25 cm) brush with a metal handle.  
Do not use freon-propelled spray-on cleaners.  
5. Use the following unsoldering technique  
a. Allow the soldering iron tip to reach normal temperature.  
(500 °F to 600 °F)  
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 circuit  
board printed foil.  
6. Use the following soldering technique.  
a. Allow the soldering iron tip to reach a normal temperature  
(500 °F to 600 °F)  
Electrostatically Sensitive (ES) Devices  
Some semiconductor (solid-state) devices can be damaged eas-  
ily by static electricity. Such components commonly are called  
Electrostatically Sensitive (ES) Devices. Examples of typical ES  
devices are integrated circuits and some field-effect transistors  
and semiconductor “chip” components. The following techniques  
should be used to help reduce the incidence of component dam-  
age caused by static by static electricity.  
1. Immediately before handling any semiconductor component or  
semiconductor-equipped assembly, drain off any electrostatic  
charge on your body by touching a known earth ground. Alter-  
natively, obtain and wear a commercially available discharg-  
ing wrist strap device, which should be removed to prevent  
potential shock reasons prior to applying power to the unit  
under test.  
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 there  
only until the solder flows onto and around both the compo-  
nent lead and the foil.  
CAUTION: Work quickly to avoid overheating the circuit  
board printed foil.  
d. Closely inspect the solder area and remove any excess or  
splashed solder with a small wire-bristle brush.

IC Remove/Replacement  
3. Solder the connections.  
Some chassis circuit boards have slotted holes (oblong) through  
which the IC leads are inserted and then bent flat against the cir-  
cuit foil. When holes are the slotted type, the following technique  
should be used to remove and replace the IC. When working with  
boards using the familiar round hole, use the standard technique  
as outlined in paragraphs 5 and 6 above.  
CAUTION: Maintain original spacing between the replaced  
component and adjacent components and the circuit board to  
prevent excessive component temperatures.  
Circuit Board Foil Repair  
Excessive heat applied to the copper foil of any printed circuit  
board will weaken the adhesive that bonds the foil to the circuit  
board causing the foil to separate from or "lift-off" the board. The  
following guidelines and procedures should be followed when-  
ever this condition is encountered.  
Removal  
1. Desolder and straighten each IC lead in one operation by  
gently prying up on the lead with the soldering iron tip as the  
solder melts.  
2. Draw away the melted solder with an anti-static suction-type  
solder removal device (or with solder braid) before removing  
the IC.  
At IC Connections  
To repair a defective copper pattern at IC connections use the  
following procedure to install a jumper wire on the copper pattern  
side of the circuit board. (Use this technique only on IC connec-  
tions).  
Replacement  
1. 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).  
1. Carefully remove the damaged copper pattern with a sharp  
knife. (Remove only as much copper as absolutely necessary).  
2. carefully scratch away the solder resist and acrylic coating (if  
used) from the end of the remaining copper pattern.  
"Small-Signal" Discrete Transistor  
Removal/Replacement  
1. 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 remain-  
ing on the circuit board.  
3. Bend a small "U" in one end of a small gauge jumper wire and  
carefully crimp it around the IC pin. Solder the IC connection.  
4. Route the jumper wire along the path of the out-away copper  
pattern and let it overlap the previously scraped end of the  
good copper pattern. Solder the overlapped area and clip off  
any excess jumper wire.  
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" with  
long nose pliers to insure metal to metal contact then solder  
each connection.  
At Other Connections  
Use the following technique to repair the defective copper pattern  
at connections other than IC Pins. This technique involves the  
installation of a jumper wire on the component side of the circuit  
board.  
Power Output, Transistor Device  
Removal/Replacement  
1. Remove the defective copper pattern with a sharp knife.  
Remove at least 1/4 inch of copper, to ensure that a hazardous  
condition will not exist if the jumper wire opens.  
2. Trace along the copper pattern from both sides of the pattern  
break and locate the nearest component that is directly con-  
nected to the affected copper pattern.  
3. Connect insulated 20-gauge jumper wire from the lead of the  
nearest component on one side of the pattern break to the  
lead of the nearest component on the other side.  
1. 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/Replacement  
Carefully crimp and solder the connections.  
1. Remove defective diode by clipping its leads as close as pos-  
sible to diode body.  
CAUTION: Be sure the insulated jumper wire is dressed so the  
it does not touch components or sharp edges.  
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  
if necessary, apply additional solder.  
Fuse and Conventional Resistor  
Removal/Replacement  
1. 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.
