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 26.0kV
(at beam 0
m
A) for the set.
2. To keep the set in a normal operation , be sure to make it function on 23.0kV
±
1.0kV (at
beam 1000
m
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
ADJUSTMENT ITEM
T his model's s etting are adjus te d in two different ways : through the I2C bus control and in the conventional analog manner. T he adjus tments via the I2C bus control include pres et-only items and variable data. 1. S etting the s ervice mode by the microproces sor.
(1). P res s and hold the local key "V OL DO W N" & "C H U P " when power on the main s witch,
T V will enter into the S E R VIC E MO DE in Adjustment Mode.(T he initial value of E E P R OM are automa tica lly pres et when new E E P R OM is us ed).
S ervice Mode also can be reached by pres sing "S ervice" key (code: 81 Hex)
(2). P res s the C H DOW N / UP key on the remote controller to select the items
one by one in Adjus tment Mode.
(3). U sing the VO LUME UP / DO W N key on the remote controller, the data ca n be modified. (4). W hen pres s the local key "V OL DO W N" & "C H UP " at the s ame time,
it will be released from the service mode.
(5) P res s the ME NU key on the remote controller to enter into NV M mode.
P res s ME NU key again to lea ve the NV M mode return to Adjus tment Mode. ( Not re comme nded to modify the data unles s a s lis te d in B US S E T U P data)
(6) P re ss both C H-U P and V OL -DO W N buttons on the T V s et s imutaneous ly or pres s
the "S E R V IC E " (81HE X) key again, it will s witch to the NOR MAL mode pos ition, and the microproces sor is out of the S E R V IC E mode.
2. F ac tory P res etting.
(1). P res s remote controller key of code "E D"for 4 seconds , the initial values are
automatically pres et.
(2). T he initial data a re pres et a s lis ted in page 5~8. (3). Make s ure whether the data need to modify or not (Initial data).
( R efer to B US S E T U P DAT A )
Note: Once the chass is has been as sembly together and in ready condition, please make
sure it's go through initialize proces s (see s ect 2 above)
P rec aution: If haven't done this initialization, malfunction might be happen.
