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 ser-
vice 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 volt-
age 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 set has an On-screen Service Menu system included in the CPU that allows remote operation for most of the
service adjustments.
2. Service Adjustments:
Press the CHANNEL UP or CHANNEL DOWN
button on the remote control handset to select the
desired service menu item you want to adjust.
Use the VOLUME + or - to adjust the data.The + or
- button will increase or decrease the data
sequentially.
3. Exit from the Service Menu
Press the MENU button to turn off the Service Menu
display.
The data which is set in the service mode is stored
into the memory IC automatically.

IC802 (EEPROM) Replacement
When IC802 (EEPROM) is replaced, IC801 (CPU) will automatically write the initial reference data into IC802 for basic TV operation.
However, the bus data should be checked and some bus data should be set up before attempting the service adjustments. (See
pages 9 ~ 10 for detailed information.)
Initial Bus Data Setup
Note: When IC802 (EEPROM) is replaced, following Service Menu should be set up for proper TV operation before attempting the
service adjustments.

Service Adjustment-4
Note: +B (+130V) Voltage and Grayscale Adjustment must
be completed before attempting HighVoltage 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 28.5KV ± 1KV and less than
32KV at 0 beam current (Brightness and contrast
minimum setting).
Note: If the picture tube is replaced, check the high
voltage.
HIGH VOLTAGE CHECK
FOCUS VR (Upper side)
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 volt-
age 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 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 trou-
ble was temporary. If there is permanent trouble such as a
damaged circuit, power cannot be restored and the circuit
will have to be repaired.

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 DeflectionYoke and remove the
3 Rubber Wedges, and slide the DeflectionYoke 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 DeflectionYoke 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 theTabs 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.
