1-2. General Guidelines
When servicing, observe the original lead dress. If a short circuit is found, replace all parts
which have been overheated or damaged by the short circuit.
After servicing, see to it that all the protective devices such as insulation barriers, insulationpapers shields are properly installed.
After servicing, make the following leakage current checks to prevent the customer from
being exposed to shock hazards.
1) Leakage Current Cold Check
2) Leakage Current Hot Check
3) Prevention of Electro Static Discharge (ESD) to Electrostatically Sensitive
1-3. Important Notice
1-3-1. Follow the regulations and warningsMost important thing is to list up the potential hazard or risk for the service personnel to
open the units and disassemble the units. For example, we need to describe properly
how to avoid the possibility to get electrical shock from the live power supply or charged
electrical parts (even the power is off).
This symbol indicates that high voltage is present inside.It is dangerous to
make any king of contact with any inside part of this product.
This symbol indicates that there are important operating and maintenance
instructions in the literture accompanying the appliance.
1-3-2. Be careful to the electrical shockTo prevent damage which might result in electric shock or re, do not expose this TV set
to rain or excessive moisture. This TV must not be exposed to dripping or splashing water,
and objects lled with liquid, such as vases, must not be placed on top of or above the TV.
1-3-3. Electro static discharge (ESD)Some semiconductor (solid state) devices can be damaged easily by static electricity. Such
components commonly are called Electrostatically Sensitive (ES) Devices. The following
techniques should be used to help reduce the incidence of component damage caused by
electros static discharge (ESD).
1-3-4. About lead free solder (PbF)This product is manufactured using lead-free solder as a part of a movement within the
consumer products industry at large to be environmentally responsible. Lead-free solder
must be used in the servicing and repairing of this product.
1-3-5. Use the genewing parts (specied parts)
Special parts which have purposes of fire retardant (resistors), high-quality sound
(capacitors), low noise (resistors), etc. are used.
When replacing any of components, be sure to use only manufacture's specified parts
shown in the parts list.

1-3-6 Safety Check after Repairment
- 04 -
Service Manual Model No.:
Conrm that the screws, parts and wiring which were removed in order to service are put
in the original positions, or whether there are the positions which are deteriorated around
the serviced places serviced or not. Check the insulation between the antenna terminal or
external metal and the AC cord plug blades. And be sure the safety of that.
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 explosion hazard.
2. Test high voltage only by measuring it with an appropriate high voltage meter or othervoltage measuring device (DVM, FETVOM, etc) equipped with a suitable high voltage
probe.
Do not test high voltage by "drawing an arc".
5. Do not defeat any plug/socket B+ voltage interlocks with which receivers covered by this
service manual might be equipped.
8. Use with this receiver only the test xtures specied in this service manual.
CAUTION: Do not connect the test xture ground strap to any heat sink in this receiver.
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 ammable mixture. Unless specied otherwise in this service manual, lubrication of contacts is not required.
Capacitors may result in an explosion hazard.
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. Capacitors may result in an explosionhazard.
9. Remove the antenna terminal on TV and turn on the TV.
10. Insulation resistance between the cord plug terminals and the eternal exposure metal
should be more than Mohm by using the 500V insulation resistance meter.
11. If the insulation resistance is less than M ohm, the inspection repair should be required.
If you have not the 500V insulation resistance meter, use a Tester. External exposuremetal: Antenna terminal Headphone jack

Electrostatically Sensitive (ES) Devices
1-3-7. Ordering Spare Parts
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. Alternatively, obtain and wear a commercially available discharging wrist
strap device, which should be removed to prevent 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 as aluminum foil, to prevent electrostatic charge buildup or
exposure of the assembly.
5. Do not use freon-propelled chemicals. These can generate electrical charges sufcient
to damage ES devices.
7. Immediately before removing the protective material from the leads of a replacement
ES device, touch the protective material to the chassis or circuit assembly into which the
device will be installed.
CAUTION: Be sure no power is applied to the chassis or circuit, and observe all other
safety precautions.
3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.
Some semiconductor (solid-state) devices can be damaged easily by static electricity.
Such components commonly are called Electrostatically Sensitive (ES) Devices.
Examples of typical ES devices are integrated circuits and some field-effect transistorsand semiconductor "chip" components. The following techniques should be used to help
reduce the ncidence of component damage caused by static by static electricity.
4. Use only an anti-static type solder removal device. Some solder removal devices not
classied as "anti-static" can generate electrical charges sufcient 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 electrically shorted together byconductive foam, aluminum foil or comparable conductive material).
8. Minimize bodily motions when handling unpackaged replacement ES devices.
(Otherwise harmless motion such as the brushing together of your clothes fabric or the
lifting of your foot from a carpeted oor can generate static electricity sufcient to damagean ES device.)
Please include the following informations when you order parts. (Particularly the Version
letter)

TO USE AC POWER SOURCEUse the AC polarized line cord provided for operation on AC.
Insert the AC cord plug into a standard polarized AC outlet.
NOTES:
■ Never connect the AC line cord plug to other than the specied voltage.Use the attached power cord only.
■ If the polarized AC cord does not t into a non-polarized AC outlet,
do not attempt to le or cut the blade. It is the user`s responsibility to have an
electrician replace the obsolete outlet.
■ If you cause a static discharge when touching the unit and the unit fails to function,
simply unplug the unit from the AC outlet and plug it back in. The unit should return to
normal operation.
