IMPORTANT SAFETY NOTICE
Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by in
the Schematic Diagram and Replacement Parts List.
It is essential that these special safety parts should be replaced with the same components as recommended in this manual to
prevent X-RADIATION, Shock, Fire, or other Hazards.
Do not modify the original design without permission of manufacturer.
General Guidance
An lsolation 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.
It will also protect the receiver and it's components from being
damaged by accidental shorts of the circuitary 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 1W), keep the resistor 10mm away from PCB.
Keep wires away from high voltage or high temperature parts.
Due to high vacuum and large surface area of picture tube,
extreme care should be used in handling the Picture Tube.
Do not lift the Picture tube by it's Neck.
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 positioin, 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 1MΩ and 5.2MΩ.
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.
Leakage Current Hot Check (See below Figure)
Plug the AC cord directly into the AC outlet.
Do not use a line Isolation Transformer during this check.
Connect 1.5K/10watt resistor in parallel with a 0.15uF 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 esposed metallic part. Any
voltage measured must not exceed 0.75 volt RMS which is
corresponds to 0.5mA.
In case any measurement is out of the limits sepcified, there is
possibility of shock hazard and the set must be checked and
repaired before it is returned to the customer.

SERVICING PRECAUTIONS
- 4 -
CAUTION: Before servicing instruments covered by this service manual and
its supplements, read and follow the SAFETY PRECAUTIONS section of this
manual. Note: If unforeseen circumstances create conflict between the following servicing precautions and any of the safety precautions, always follow the
safety precautions. Remember: Safety First.
General Servicing Precautions
1. a. Always unplug the instrument AC power cord from the AC power source
before: (1) removing or reinstalling any component, circuit board, module,
or any other instrument assembly. (2) disconnecting or reconnecting any
instrument electrical plug or other electrical connections. (3) connecting a
test substitute in parallel with an electrolytic capacitor in the instrument.
Caution: A wrong part substitution or incorrect polar-ity installation of
electrolytic capacitors may result in an explosion hazard.
b. Do not defeat any plug/socket B+ voltage interlocks with which instru-
ments covered by this service manual might be equipped.
c. 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.
d. Always connect a test instrument’s ground lead to the instrument chassis
ground before connecting the test instrument positive lead.
Always remove the test instrument ground lead last.
Note: Refer to the Safety Precautions section of this manual.
2. The service precautions are indicated or printed on the cabinet, chassis, or
components. When servicing, follow the printed or indicated service precautions and service materials.
3. The components used in the unit have a specified flame resistance and
dielectric strength. When replacing any components, use components
which have the same ratings. Components identified by shading, by
*
, or
by in the circuit diagram are important for safety or for the characteristics
of the unit. Always replace with the exact replacement components.
4. An insulation tube or tape is sometimes used and some components are
raised above the printed wiring board for safety. The internal wiring is sometimes clamped to prevent contact with heating components. Install them as
they were.
5. After servicing, always check that the removed screws, components, and
wiring have been installed correctly and that the portion around the service
part have not been damaged. Further, check the insulation between the
blades of the attachment plug and accessible conductive parts.
INSULATION CHECKING PROCEDURE
Disconnect the attachment plug from the AC outlet and turn the power on.
Connect the insulation resistance meter (500 V) to the blades of the attachment plug. The insulation resistance between each blade of the attachment
plug and accessible conductive parts (Note 1) should be more than 1 Mohm.
Note: Accessible conductive parts include metal panels, input terminals, earphone jacks, etc.
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 incidence of component damage caused by static electricity.
1. Immediately before handling any semiconductor component
or semiconductor-equipped assembly, drain off any electrostatic charge on the body by touching a known earth ground.
Alternatively, obtain and wear a commercially available discharging wrist strap device, which should be removed for
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 solder removal device. Some solder
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 charge 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
t.(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 replace
ment ES devices. (Otherwise, seemingly harmless motion,
such as the brushing together of your clothing or the lifting of
your foot from a carpeted floor, can generate static electricity
sufficient to damage an ES device.)
