SAFETY NOTICE
Many electrical and mechanical parts in LCD television
have special safety-related characteristics.
These characteristics are often not evident from visual
inspection, nor can protection afforded by them be
necessarily increased by using replacement components
rated for higher voltage, wattage and etc.
Replacement parts which have these special safety
characteristics are identified in this manual; electrical
components having such features are identified by“ å”
IMPORTANT SERVICE SAFETY PRECAUTION
ËService work should be perfomed only by qualified service technicians who are thoroughly
familiar with all safety checks and the servicing guidelines which follow:
and shaded areas in the Replacement Parts Lists and
Schematic Diagrams .
For continued protection, replacement parts must be
identical to those used in the original circuit.
The use of a substitute replacement parts which do not
have the same safety characteristics as the factory
recommended replacement parts shown in this service
manual, may create shock, fire or other hazards.
WARNING
1. For continued safety, no modification of any circuit
should be attempted.
2. Disconnect AC power before servicing.

TEST PROBE
•Use an AC voltmeter having with 5000 ohm per volt, or
higher, sensitivity or measure the AC voltage drop
across the resisor.
•Connect the resistor connection to all exposed metal
parts having a return to the chassis (antenna, metal
cabinet, screw heads, knobs and control shafts,
escutcheon and etc.) and measure the AC voltage drop
across the resistor.
All checks must be repeated with the AC cord plug
connection reversed. (If necessary, a nonpolarized
adaptor plug must be used only for the purpose of
completing these checks.)
Any reading of 0.75V peak (this corresponds to 0.5
milliamp.peak AC.) or more is excessive and indicates
a potential shock hazard which must be corrected
before returning the monitor to the owner.
BEFORE RETURNINGTHE RECEIVER
(Fire & Shock Hazard)
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, and check 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, insulation materials, cabinet backs,
adjustment and compartment covers or shields,
isolation resistor-capacitor networks, mechanical
insulators and etc.
3. To be sure that no shock hazard exists, check for
leakage current in the following manner.
•Plug the AC cord directly into a 110~240 volt AC outlet,
and connect the DC power cable into the receiver's
DC jack.(Do not use an isolation transformer for this
test).

ADJUSTING PROCEDURE OF EACH SECTION
[1] Entering the MAIN side adjustment process mode
There are three methods below.
1) Press the “Adjustment process key” on the remote control after turning on the power.
2) Pressing both the MENU key and the TV/VIDEO key on the main body, turn on the power. Then, press the
volume DOWN key and the tuning DOWN key at the same time.
3) Turn on the power with falling either KEY4 (pin (81) of microprocessor) or KEY5 (pin (82) of microprocessor) to“L”.
[Note] For the method 3), the ROM is initialized at the same time.Therefore, 3) must be executed, if IC2004 or
IC2001 is changed. For 1) or 2), the main body only enters the MAIN side adjustment process.
[2] Entering theTUNER side adjustment process mode
4) Entering the TUNER side adjustment process

[4] Lamp error detection
4-1. Functional description
This LCD colour television has a function (lamp error detection) to be turned OFF automatically for safety
when the lamp or lamp circuit is abnormal.
If the lamp or lamp circuit is abnormal, or some other errors happen, and the lamp error detection is executed,
the followings occur.
1The main unit of television is turned OFF 5 seconds after it is turned ON. (The power LED on the front side
of TV turns from green to red.)
2If the situation 1happens 5 times sequentially, television can not be turned ON.(The power LED remains
red.)
4-2. Countermeasures
4-2-1.Check when turning OFF the lamp error detection
When television is turned OFF by the lamp error detection mentioned above, it enters the adjustment
process with the power LED red.Entering the adjustment process turns OFF the error detection and turns
ON TV.
This enables the operation check to detect errors in the lamp or lamp circuit.
Check whether "ERROR NO RESET" on line 7, page 1 of the adjustment process is 1 or more. If it is 1 or
more, it indicates the lamp error detection was executed.
4-2-2.Resetting of the lamp error count
After confirming that the lamp or lamp circuit is normal, reset the lamp error count. Select "ERROR NO
RESET" on line 5, page 1 of the adjustment process and set the number to 0 using the volume button.
