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.

Safety Notice

SAFETY PRECAUTIONS

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 pro-

vided 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 resistor-capacitor 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 .

Service Information

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 27 of the CPU to go continually Low (less than

0.75V) for about one second. The CPU detects that this has occurred and outputs the signal from pin 31 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.

■ Protection Circuit

Mechanical Disassemblies

CABINET BACK REMOVAL

1. Refer to Figure 1, remove 10 screws.

2. Pull off cabinet back and remove.

CHASSIS REMOVAL

1. Remove cabinet back.

2. Discharge the picture tube anode (2nd anode lead) to the dag
coating (picture tube grounding lead).

3. Disconnect Degaussing coil socket (KE), Picture tube socket,
Deflection yoke connector (KDY), Speaker connectors (K002
and K003), and 2nd anode lead.

4. Remove chassis completely by sliding it straight back.

PICTURE TUBE REMOVAL

CAUTION: Do not disturb the deflection yoke or magnet

assembly on the picture tube neck. Care must be taken
to keep these assemblies intact, unless picture tube is
being replaced . Discharge the picture tube to the coat­ing before handling the tube.

1. Remove chassis, referring to Chassis Removal instructions.

2. Place cabinet’s front face down on the soft surface.

3. Remove the screw on each corner of the picture tube and

GENTLY lift the picture tube out of the cabinet.

4. Install a replacement picture tube in reverse order.
Properly install the degaussing coil and picture tube ground
ing lead on the picture tube. See Figure 2.

Note: If the Picture Tube is being replaced, mount the

Degaussing Coil on the picture tube. See Figure 2.

Service Adjustments with Replacing Memory IC (IC802)

Note: The CPU (IC801) and memory IC (IC802) store the service adjustments data and controls data for each

circuit. When the Memory IC(IC802) is replaced, some of the service adjustments should be readjusted to
obtain the best performance. The necessary service adjustments are carried out by using the RC handset.
Please set up the TV set with following steps [1] to [2].
