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 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. When repairing the circuit, be sure not to increase the high volta ge to more than 30.0kV

(at beam 0

µA) for the set.

2. To keep the set in a normal opeartion , be sure to make it function on 27.5kV

±1.5kV (at

beam 1,350

µA) 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, perf orm the follo wing 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 fishpaper s,

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 w ays: 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.

1. Setting the service mode by the microprocessor.

1. Short TP1001 & TP1002 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. Disconnect TP1001 & TP1002 to switch to the normal mode (OFF) position, and the microprocessor is

in out of the service mode.

2. Factory Presetting.

1. Short TP1001 & TP1002 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 b ytes).

2. The initial data are preset as listed in page E-9, E-10 & E-11.

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 TP1001 & TP1002 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

(UAF Series type RH-iX3417CE Attachment)

4. Trouble indications

If the set is interrupted by IIC bus line error, the following indicators work to identify a spot in trouble.
