IMPORTANT SERVICE NOTES

Maintenance and repair of this receiver should be done by qualified

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 followin

precautions should be observed:

1. 20A1-RU : When repairing the circuit, be sure not to increase the high voltage to more

than 26.4kVmax (at beam 0.1

A) for the set.

21A1/2-RU :When repairing the circuit, be sure not to increase the high voltage to more

than 26.5kVmax (at beam 0.1

A) for the set.

2. 20A1-RU : To keep the set in a normal operation, be sure to make it function on

24.5kV

1.5kV(at beam 1100

A) in the case of the set. The set has been

factory -Adjusted to the above-mentioned high voltage.

21A1/2-RU :To keep the set in a normal operation, be sure to make it function on

24.8kV

1.5kV(at beam 1100

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 repairs, 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

C bus control and in the conventional

analog manner. The adjustments via the I

C bus control include preset-only items and variable data.

1. Setting the service mode by the microprocessor.

1. Short JA 122 & JA 124 for 1 second and release to switch to the service mode position, and the

microprocessor is in input mode. (Adjustment through the I

C 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 122 & JA 124 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 122 & JA 124 for 1 second and release to switch to the service mode position and turn on the

main power switch.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 5 & 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 JA122 & JA124 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

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.
