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, 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. Important Notice
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.

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.

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 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).

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.

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

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 component or semiconductorequipped 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.
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 solder removal devices not

'RQRWXVHIUHRQSURSHOOHGFKHPLFDOV7KHVHFDQJHQHUDWHHOHFWULFDOFKDUJHVVXI¿FLHQW
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 by
conductive foam, aluminum foil or comparable conductive material).
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.
8. Minimize bodily motions when handling unpackaged replacement ES devices.
(Otherwise harmless motion such as the brushing together of your clothes fabric or the
OLIWLQJRI\RXUIRRWIURPDFDUSHWHGÀRRUFDQJHQHUDWHVWDWLFHOHFWULFLW\VXI¿FLHQWWRGDPDJH
an ES device.)
