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
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, adjust-
ment covers or shields, barriers, isolation resistor-
capacitor networks etc.. Before returning any
television to the customer, the service techni-
cian 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 hazard-
ous 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 .

This adjustment is used to do a fine tuning of the channels with poor reception after they have been stored by the
automatic tuning.
This function is available for one channel only and the fine-tuned channel is memorized into IC802 (EEPROM).

HIGH VOLTAGE CHECK
Note: +B (+130V) 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 25KV ± 1KV and less than
28KV at 0 beam current (Brightness and contrast
minimum setting).
Note: If the picture tube is replaced, check the high
voltage.
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 restor-
ing 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.

FOCUS ADJUSTMENT
1. Receive the monochrome circular pattern.
2. Set the brightness to normal and contrast to maxi-
mum.
3. Adjust the focus control on the F.B.T. for the best
focus on the screen centre.

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 mag-
nets 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 for-
ward.
4. Rotate and spread the Tabs of the two Purity Magnets to
centre 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 uniform-
ity, 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 for-
ward 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 cen-
tre 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
horizontal lines in the centre area of the picture screen. Refer
to figure 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 appropri-
ate position by putting the wedges as illustrated. Tighten screw
holding the Deflection Yoke.
