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 net-
works 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 con-
structed 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 23 of the CPU to go continually Low 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.

Service Adjustments with Replacing Memory IC(IC801)
Note: The CPU (IC201) and memory IC (IC801) store the service adjustments data and controls data for each
circuit.When the Memory IC(IC801) 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].
[1] Initializing Procedure
1. Put a new memory IC.
2. Turn on the TV set.
3. Press and hold the TV/AV Selector on the TV set for more than 2 seconds. The following picture appears on the
screen.
4. Press the PROGRAMME UP on the TV set while the above On-Screen Display is still on the screen. The following
picture appears on the screen.
This completes the initialization of memory IC.
Following shows the initialized contents of memory data by this procedure.
- Plug & Play : No executed
- Inhibit Data : Cancelled
- Ch Skip Data : Cancelled
- Sound Volume Data : 10/63 steps.

Service Adjustments
Following adjustments are not required to readjust when replacing the memory IC.
Note: +B (+130V) Voltage Check and Grayscale Adjustment
mustbecompletedbeforeattemptingHigh VoltageCheck.
(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) Maximize the beam current by adjusting the contrast
and brightness controls to maximum. Confirm high
voltage is within 26.5 KV and 28.5 KV at maximum
beam current.
(4) Eliminate the beam current by adjusting the contrast
and brightness controls to minimum. Confirm high
voltage does not exceed 30.0 KV at zero beam current.
If reading is not within range, check horizontal circuit.
No high-voltage adjustment is provided on this chassis.

(Pre-set) is not possible. The Channel Swapping function also
is not possible.
2Select an item of the special functions by pressing the PROGRAMME UP or DOWN button on the remote control
or the TV set.
3Set the selected special function “ ON “ by pressing the VOLUME + or - button. To cancel, set to “ OFF”.
(2) Tuning Lock setting
The following special functions can be set up on this TV
set.
With this function, a maximum sound volume limit can be set at
any level.
(3) Music Mode setting
When Music Mode is ON, Programme position from “247” to
“255” and “0” are set Music Mode. Only sound is provided and
any picture is not on the screen under Music Mode.
Set AV-START to ON and every time the TV set is switched on,
AV1 position will be the initial programme position.

CAUTION: The Convergence and Purity adjustments have been made at the factory. Readjustment
should be made only after picture tube or deflection yoke replacement, following the steps below:
PURITY ADJUSTMENT
1. Demagnetize the picture tube and receiver using an external
degaussing coil. When replacing picture tube or deflection
yoke, mount deflection yoke and purity-convergence magnets
assembly properly, see figures 1 and 4.
2. Turn Red and Blue guns off and provide only Green raster.
Rotate Screen control to fully counterclockwise. Rotate Red
and Blue Bias controls fully counterclockwise. Slowly rotate
Green Bias control clockwise to produce Green raster.
3. Loosen the screw holding the Deflection Yoke and remove the
3 Rubber Wedges, and slide the Deflection Yoke fully forward.
4. Rotate and spread the Tabs of the two Purity Magnets to cen-
tre the vertical green belt in the picture screen. The Purity
Magnets are also adjusted to obtain vertical centring of the
raster.
5. Slowly slide the Deflection Yoke backward until a uniform
green screen is obtained.
6. Check the purity of the red and blue screens for uniformity,
turn off other colours to check this (use bias controls).
Readjust the yoke position if necessary until all screens are
pure.
7. Adjust each Bias control and screen control to obtain white
raster. Refer to Gray Scale Adjustment. If part of the picture
screen is coloured, adjust the Deflection Yoke position forward
or backward slightly.
8. Tighten the mounting screw of the Deflection Yoke. Adjust
Convergence next.
CENTRE CONVERGENCE ADJUSTMENT
1. Use a dot crosshatch pattern signal.
2. Turn Red and Blue guns on and turn off Green gun. Adjust the
angle between the Tabs of the Four Pole Magnet 1 and 2, and
superimpose the Red and Blue vertical lines in the centre area
of the picture screen. Refer to figure 2.
3. Keeping the mutual angle of the Tabs of the Four Pole Magnet
turn them together to superimpose the Blue and Red horizon-
tal lines in the centre area of the picture screen. Refer to fig-
ure 2.
4. Turn Green gun on and adjust Six Pole Magnet 3 and 4 that
the Green line superimposed on the Red/Blue lines.
This is the same procedure used in steps 2 and 3.
Refer to figure 3.
OUTER AREA CONVERGENCE ADJUSTMENT
Slightly loosen the screw holding the Deflection Yoke. Adjust the
Deflection Yoke to converge the detail in the outer area (left side
and right side) of the picture screen by orbital movement of the
front of the Yoke, then secure the Deflection Yoke in appropriate
position by putting the wedges as illustrated. Tighten screw hold-
ing the Deflection Yoke.
