WARNING
The chassis in this receiver is partially hot. Use an isolation transformer between the line cord plug and power receptacle, when servicing this chassis. To prevent electric shock, do not remove cover. No user – serviceable parts inside. Refer servicing to qualified service personnel.

IMPORTANT SERVICE NOTES
Maintenance and repairing of this receiver should be done by quali-
fied service personnel only .
SERVICE OF HIGH VOLTAGE SYSTEM AND PIC-
TURE TUBE
When servicing the high voltage system, remove static charge from it by
Connecting a 10K ohm Resistor in series with an insulated wire(such as a
test probe) between picture tube dag and 2nd anode lead. (AC line cord
should be disconnected from AC outlet.)
1. Picture tube in this receiver employs integral implosion protection.
2. Replace with tube of the same type number for continued safety.
3. Do not lift picture tube by the neck.
4. Handle the picture tube only when wearing shatterproof goggles and after discharging
the high voltage completely.
X-RAY
This receiver is designed so that any X-Ray radiation is kept to an absolute
Minimum. Since certain malfunctions or servicing may produce potentially
hazardous radiation with prolonged exposure at close range, the following
precautions should be observed:
14E2-RU
1. When repairing the circuit, be sure not to increase the high voltage to more than 25.2kV(at
beam 0
µ
A) for the set.
2. To keep the set in a normal operation , be sure to make it function on 22.7kV
±
1.5kV(at
beam 800
µ
A) in the case of the set. The set has been factory - Adjusted to the above-
mentioned high voltage.
21E2-RU
1. When repairing the circuit, be sure not to increase the high voltage to more than 28.0kV(at
beam 0
µ
A) for the set.
2. To keep the set in a normal operation , be sure to make it function on 24.8kV
±
1.5kV(at
beam 1100
µ
A) in the case of the set. The set has been factory - Adjusted to the above-
mentioned high voltage.
*If there is a possibility that the high voltage fluctuates as a result of the repairing,
never forget to check for such high voltage after the work.
3. Do not substitute a picture tube with unauthorizerd types and/or brands which may
cause excess X-ray radiation.
BEFORE RETURNING THE RECEIVER
Before returning the receiver to the user, perform the following safety Checks.
1. Inspect all lead dress to make certain that leads are not pinched or that hardware is not
lodged between the chassis and other metal parts in the receiver.
2. Inspect all protective devices such as non-metallic control knobs, insulating fishpapers,
cabinet backs, adjustment and compartment covers or shields, isolation resistor- ca-
pacity networks, mechanical insulators etc.

ADJUSTMENT PRECAUTIONS
This model's setting are adjusted in two different ways: through the I
2
C bus control and in the conventional
analog manner. The adjustments via the I
2
C bus control include preset-only items and variable data.
CAUTION: Make sure TV Set is in "Normal Condition" before switch to Service Mode for adjustment.
1. Setting the service mode by the microprocessor.
1 Short JA 137 & JA 138 for 1 second and release to switch to the service mode position, and the
microprocessor is in input mode. (Adjustment through the I2C bus control). (Use JWS Key to set as
well).
2 Press the CH DOWN / UP key on the remote controller to get ready to select the mode one by one.
3 Press the CH DOWN / UP key on the remote controller to select the modes reversibly one by one.
4 Using the VOLUME UP/ DOWN key on the remote controller, the data can be modified.
5 Short JA 137 & JA 138 for 1 second and release to switch to the normal mode (OFF) position, and the
microprocessor is in out of the service mode.
2. Factory Presetting.
1 Short JA 137 & JA 138 then turn "ON" the main power and release to switch to the Service Mode
position.Initial values are automatically preset, only when a new EEPROM is used (Judge with the first
4 bytes ).
2 The initial data are preset as listed in page 6.
3 Make sure the data need modify or not (Initial data).
Note: Once the chassis has been assembly together and ready to be POWER ON for the FIRST TIME,
make sure to short JA137 & JA138 to switch to the service mode position first and then turn on the
main power switch (See 2-(1) above).
Precaution: If haven't done this initiation, it may possibly generate excessive Beam current.
3. For reference please check with memory map
(GA-1AM Series type RH-IX3368CE Attachment)

1 1. Get the tuner ready to receive the CH. E - 9
signal,but with no signal input.
Adjust the PLL data.
2. Connect the sweep generator's output cable to
the tuner antenna. ( RF SWEEP )
3. Adjust the sweep generator's to 80dBuV.
4. Connect the response lead ( use LOW IMPED-
ANCE probe with wave detector ; see Fig.1 ) to
the tuner's IF output terminal. ( This terminal
must have the probe alone connected ).
5. Set the RF AGC to 0 - 6 V with no saturation with
the waveform.
6. Adjust the tuner IF coil to obtain the waveform as
shown in Fig. 2.
Note:Be sure to keep the tuner cover in position

4. Change the antenna input signal to 63~67dBµV,
and make sure there is no noise.
5. Turn up the input signal to 90~95 dBµV to be sure
that there is no cross modulation beat.

2. Degauss the CRT enough with the degausing coil.
Note: Follow the Job Instruction Sheet to ad-
just the magnetic field.
3. Maintain the purity magnet at the zero magnetic

the deflection coil upward.
b) Fig. 5-2: Drive the wedge at points "b" and "c"
and swing the deflection coil downward.
c) Fig. 5-3: Drive the "c" wedge deeper and swing
the deflection coil rightward.
d) Fig. 5-4: Drive the "b" wedge deeper and swing
