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, insulation papers
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

1-3-1. Follow the regulations and warnings
Most 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 shock
To 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).

DevicesSome 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 transistors and semiconductor "chip"
components. The following techniques should be used to help reduce the ncidence of component
damage 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.

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.
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 (speci  ed parts)
Special parts which have purposes of  re retardant (resistors), high-quality sound (capacitors),
low noise (resistors), etc. are used.
When replacing any of components, be sure to use only manufacture's speci  ed parts shown in
the parts list.

1-3-6 Safety check after repairment
Con  rm 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.

Servicing Precautions
Precautions
Precautions
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:
CAUTION:
CAUTION:
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 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:
CAUTION:
CAUTION:
CAUTION:
This is a  ammable mixture.
Unless speci  ed otherwise in this service manual, lubrication of contacts is not required.
Capacitors may result in an explosion hazard.
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. Capacitors may result in an explosion hazard.
8. Use with this receiver only the test  xtures speci  ed in this service manual.
CAUTION:
CAUTION:
CAUTION:
CAUTION: Do not connect the test  xture ground strap to any heat sink in this receiver.
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 exposure metal:
Antenna terminal Headphone jack.
12. Use only a grounded-tip soldering iron to solder or unsolder ES devices.
13. Use only an anti-static type solder removal device. Some solder removal devices not
classi  ed as "anti-static" can generate electrical charges suf  cient to damage ES devices.
14. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to
damage ES devices.
15. 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 by
conductive foam, aluminum foil or comparable conductive material).
16. 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:
CAUTION:
CAUTION:
CAUTION: Be sure no power is applied to the chassis or circuit, and observe all other safety
precautions.
17. 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 suf  cient to damage an ES device.)
1-3-7. Ordering Spare Parts
Please include the following informations when you order parts. (Particularly the Version letter)
1. Model number, serial number and software version
The model number and serial number can be found on the back cover of each product. Software
version can be found in the Spare Parts List.
2. Spare part No. and description
Spare part No. and description can be found in the Spare Parts List.
