Give complete “SERVICE REF. NO.” for
parts order or servicing. It is shown on the
rating plate at the cabinet back of the unit.
This T.V. receiver will not work properly in
foreign countries where the television transmission system and power source differ from
the design specifications. Refer to the specification table.
1: An isolation transformer should be connected in the
power line between the receiver and the AC line
when a service is performed on the primary of the
converter transformer of the set.
2: Comply with all caution and safety-related notes
provided on the cabinet back, inside the cabinet, on
the chassis or the picture tube.
3: When replacing a chassis in the cabinet, always
be certain that all the protective devices are
installed properly, such as, control knobs, adjustment covers or shields, barriers, isolation resistorcapacitor networks etc.. Before returning any
television to the customer, the service technician must be sure that it is completely safe
to operate without danger of electrical shock.
X-RADIATION PRECAUTION
The primary source of X-RADIATION in television receiver is the picture tube. The picture tube is specially constructed to limit X-RADIATION emissions. For continued X-RADIATION protection, the replacement tube must
be the same type as the original including suffix letter. Excessive high voltage may produce potentially hazardous X - RADIATION. To avoid such hazards, the high voltage must be maintained within specified limit. Refer
to this service manual, high voltage adjustment for specific high voltage limit. If high voltage exceeds specified
limits, take necessary corrective action. Carefully follow the instructions for + B1 volt power supply adjustment,
and high voltage check to maintain the high voltage within the specified limits.
PRODUCT SAFETY NOTICE
Product safety should be considered when a component replacement is made in any area of a receiver.
Components indicated by mark in the parts list and the schematic diagram designate components in which
safety can be of special significance. It is particularly recommended that only parts designated on the parts list
in this manual be used for component replacement designated by mark . No deviations from resistance
wattage or voltage ratings may be made for replacement items designated by mark .

HIGH VOLTAGE CHECK
Note: +B (+140V) Voltage and Grayscale Adjustment must be completed before attempting High Voltage Check.
1. Connect high voltage voltmeter negative lead to ground, and connect + lead to anode of picture tube.
2. Tune receiver to an active channel and confirm TV is operating properly.
3. The high voltage must be 28KV ± 1KV and less than 29.5KV at 0 beam current (Brightness and contrast minimum
setting).
Note: If the picture tube is replaced, check the high voltage.
Protection Circuit
This TV set has a built-in power supply protection circuit.
It is provided to protect the TV set in case of a power supply circuit malfunctions. When something abnormality occurs
during TV reception, the TV set goes to the stand-by mode.
When an abnormality occurs during TV reception, it causes pin 23 of the CPU to go continually Low voltage for
about one second. The CPU detects that this has occurred and outputs the signal from pin 36 to switch off the
power supply lines.
Releasing the protective circuit and restoring power supply
To release the protective circuit and restore power supply, turn the power to the TV set OFF and then ON again via
either the main power switch or the ON-OFF button on the remote control. This will work only if the power supply trouble was temporary. If there is permanent trouble such as a damaged circuit, power cannot be restored and the circuit
will have to be repaired.

Product safety should be considered when a component replacement is made in any area of a receiver.
Components indicated by a ! mark in this parts list and the circuit diagram show components whose value have
special significance to product safety. It is particularly recommended that only parts specified on the following parts
list be used for components replacement pointed out by the mark.
Note: Parts order must contain Service Ref. No., Part No., and descriptions. The main PCB unit will be supplied without tuner and
flyback transformer. They should be ordered separately.

PRODUCT SAFETY NOTICE:
Product safety should be considered when a
component replacement is made in any area
of a receiver.
Components indicated by a mark in this
circuit diagram show components whose
values have special significance to product
safety. It is particularly recommended that only
parts specified on the part service manual be
used for components replacement pointed out
by the mark.
THE SERVICE PRECAUTION:
The area enclosed by this line( ) is directly connected with AC mains voltage.
When servicing the area, connect an isolating transformer between TV receiver and AC
line to eliminate hazard of electric shock.

CIRCUIT DIAGRAM NOTICE:
1. All resistance value are in ohms, K=1,000, M=1,000,000.
2. All resistance rated wattages are 1/6W unless otherwise noted.
3. Excepting electrolytic capacitors, all capacitance values of less than 1
are expressed in µ F and more than 1 are pF.
4. All capacitance rated voltages are 50V unless otherwise noted.
5. All inductance values are in µ H.
6. Voltage readings take with a "VTVM" are from point indicated chassis
ground. Voltage readings taken by using NTSC colour bar signal are
with all controls at normal position. Some voltage may vary with signal
strength.
7. Waveform were taken with NTSC colour bar and controls adjusted for
normal picture. Waveforms were taken by using a wide band oscillo scope and a low capacity probe.
8. This circuit diagram covers a basic or representative chassis only.
There may be some components or partial circuit differences between
the actual chassis and the circuit diagram.
9. Parts specified with "X" are not installed in this model.10. Parts specified
with "J" are just jumper wires.
