IMPORTANT SERVICE NOTES
Maintenance and repair of this receiver should be done by qualified service personnel only .
SERVICE OF HIGH VOLTAGE SYSTEM AND PIC­TURE 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 voltage to more than 30.0kV
(at beam 0
µ
A) 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
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 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- ca­pacity 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.
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).
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 bytes).
2. The initial data are preset as listed in page 6 & 7.
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-C Series type RH-IX3410CEN5, RH-IX3412CEN5 Attachment)
4. Trouble indications
If the set is interrupted by IIC bus line error, the following indicators work to identify a spot in trouble.

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 80dBµV.
4. Connect the response lead ( use LOW IMPED­ANCE 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 posi-
tion during this adjustment.
RF-AGC TAKE OVER POINT AD­JUSTMENT (I2C BUS CONTROL)
1. Receive "PAL COLOUR BAR" signal. » Signal Strength: 54 ± 1 dBµV (75 ohm open)
2. Connect the oscilloscope to TP201 (Tuner’s AGC Terminal) as shown in Fig. 3.
3. Call "AGC" mode in service mode. Adjust the "AGC" bus data to obtain the Tuner output pin drop 0.1V below maximum voltage.
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.
Note: For the 50 ohm signal
strength gauge, when not using 50/75 impedance adapter, signal strength is 52
