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.
SERVICE MANUAL
In the interests of user-safety (Required by safety regulations in some countries) the set should be restored

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 following
precautions should be observed:
1. When repairing the circuit, be sure not to increase the high voltage to more than 28.6kV
(at beam 0
µ A) for the set.
2. To keep the set in a normal operation , be sure to make it function on 27.0kV
± 1.5kV (at
beam 1,100
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- 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 IN “NORMAL CONDITION” BEFORE SWITCH TO SERVICE MODE FOR
ADJUSTMENT.
1. Setting the service mode by the microprocessor.
1. ShortJA304 & JA 307 , then tv setwillswitch to the service mode position, andthemicroprocessor
is in input mode. (Adjustment through the I2C bus control). (Use JWS Key to set as well).
2. Press the MENU key on the remote controller to get ready to select the mode (Adjustment
mode, Setting mode, Check mode and Option mode) one by one.
3. Press the CH DOWN / UP key on the remote controller to select the items inAdjustment mode,
Setting mode and Option mode.
4. Using the VOLUME UP/ DOWN key on the remote controller, the data can be modified.
5. In Check mode the data cannot be changed.
6. Disable the short of JA 304 & JA 307, it will switch to the normal mode (OFF) position, and the
microprocessor is out of the service mode.
2.Factory Presetting.
1. Short JA 304 & JA 307, then turn ON the main power and release the shorted JA304 & JA307
after raster appeared on the screen. 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 4-2, 5-1, 5-2 & 6-2.
3. Make sure the data need modification 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 JA304 & JA307 to switch to the service mode position first and then turn on the main
power switch (See 2-11
11
1above).
Precaution: If haven’t done this initiation, it may possibly generate excessive Beam current.
3. For reference please check with memory map.
