IMPORTANT SERVICE NOTES
[1] IMPORTANT SERVICE NOTE
IMPORTANT SERVICE NOTES
Maintenance and repairing 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 the same type number of picture tube 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, please make sure do not increase the high voltage of the set
to more then 30kV (at beam 0 A).
2. To keep the set in a normal operation, please make sure it's function at 26.0kV 1.5kV
(at beam 1700 A). 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 repaires,
never forget to check for such high voltage after the work.
3. Do not substitute a picture tube with unauthorized types and/or brands which may cause
excessive 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-metal control knobs, insulating fishpapers,
cabinet backs, adjustment and compartment covers or shields, isolation resistor- capacity networks, mechanical insulators etc.

CHAPTER 3.
[1] ADJUSTMENT PRECAUTIONS
This model's setting are adjusted in two different ways: through the I2C bus control and in the
conventional analog manner. The adjustments via the I2C bus control include preset-only items and
variable data.
1. Setting the service mode by the microprocessor.
ADJUSTMENT PRECAUTIONS
ADJUSTMENT PRECAUTIONS
(1). Press and hold the local key "VOL DOWN" & "CH UP" when power on the main switch,
TV will enter into SERVICE MODE. (The initial values of EEPROM are automatically
preset when new EEPROM is used.)
(2). Press the CH DOWN / UP key on the remote controller to select the setting items
one by one.
(3). Using the VOLUME UP/DOWN key on the remote controller, the data can be modified.
(4). When press the local key "VOL DOWN" & "CH UP" at the same time, it will be released
from the service mode.
2. Factory Presetting.
(1). Press remote controller key of code "ED" for 4 seconds, the initial values are
automatically preset.
(2). The initial data are preset as listed in page 3 - 4 , 3 - 5 and 3 - 6.
(3). Make sure whether the data need to modify or not (Initial data).
Note:Once the chassis has been assembly together and in ready condition, please make
sure it's go through initialize process (see sect 2 above)
Precaution: If haven't done this initialization, malfunction might be happen.
