l Information

1 -1. 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, 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

1-2. Important Notice

1-2-1. Follow the regulations and warnings

Most important thing is to list up the potential hazard or risk f or 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

kind 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.

1-2-2. Be careful to the electrical shock

To prevent damage which might result in electric shock or fire, do not expose this TV set to
rain or excessive moisture. This TV must not be exposed to dripping or splashing water, and
objects fi lled with liquid, such as vases, must not be placed on top of or above the TV.

1-2-3. Electrostatic discha rge (E SD)

Som e 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
electrosta tic discharge (ESD).

Electrostatically Sensitive (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 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 co

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, pla
conductive surface such as aluminum foil, to prevent electrostatic charge buildup or exposure of
the assembly.

1-2-4. 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.

1-2-5. Use the genewing parts (specifi ed parts)

Special parts which have purposes of fi 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 specifi ed parts shown in
the parts list.

Safety Component

Ɣ Components identifi ed by mark have special characteristics important for safety.

1-2-6. Safety check after repairment

Confi 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.

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

c. Connecting a test substitute in parallel with an electrolytic capacitor in the receiver.

any receiver electrical plug or other electrical connection.

CAUTION:

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

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 non­abrasive applicator; 10% (by volume) Acetone and 90% (by volume) isopropyl alcohol (90%-99%
strength).

CAUTION:

Unless specifi 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.

A wrong part substitution or incorrect polarity installation of electrolytic capacitors

assemblies.

This is a fl ammable mixture.

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 be
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 fi xtures specifi ed in this service manual.

CAUTION:

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.

Do not connect the test fi xture ground strap to any heat sink in this receiver.

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:

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

classifi ed as "anti-static" can generate electrical charges suffi 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 f rom its protective packag

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 w

CAUTION:

precautions.

17. Minimize bodily motions when handling unpa ckaged replacement ES devices. (Otherwise
harmless motion such as the brushing together of your clothes fabric or the lifting of your foot
from a carpeted fl oor can generate static electricity suffi cient to damage an ES device.)

Be sure no power is applied to the chassis or circuit, and observe all other safety

e until immediately
