1. Application Object
These instructions are applied to all of the MODELS of LCD
MONITOR, ML-038A chassis.
2. Notes
(1) Because this is not a hot chassis, it is not necessary to use
an isolation transformer. However, the use of isolation
transformer will help protect test instrument.
(2) Adjustment must be done in the correct order. But, it can
be changed in consideration of mass production.
(3) The adjustment must be performed in the circumstance of
25±5°C of temperature and 65±10% of relative humidity if
there is no specific designation.
(4) The input voltage of the receiver must keep 230V, 60Hz in
adjusting.
[
Input voltage is possible from 195V to 264V because the
power voltage applied to this chassis is Wide-Range. But,
adjustment should be operated in 230V/60Hz if there is no
specific designation.
(5) The receiver must be operated for about 15 minutes prior
to the adjustment.
¤
After receiving 100% white pattern(06CH), the receiver
must be operate prior to adjustment.(Or white condition
in HEAT-RUN mode)
¤Ł
Enter into HEAT-RUN mode
- Select ‘White’ by pressing ‘POWER ON’ key on SVC
communicator.
[Caution] If you turn on a still screen more than 20 minutes , a
afterinage may be occur in the black level part of the
screen.
3. Whole Assembly Adjustment
<Caution> Each PCB Assy must be checked by Check JIG Set
before assembling.(Be careful about power PCB
ASSY which can give a fatal damage to the LCD
Module)
3-1. White Balance Adjustment
(1) Required Equipment
Color analyzer(CA-100 or same production)
(2) Connection Diagram of Equipment for
Measuring (Automatic Adjustment)
Connect RS-232C to Adjustment Equipment and SET.
Automatization operating room has in charge of managing
and repairing about adjusting equipment.
Only adjust HIGH LIGHT and RGB input adjusts R-H, G-H
automatically.
Automatic adjustment equipment decides the values of R-
GAIN/G-GAIN/B-GAIN by correcting color coordinates/white
balance and transmits them into SET(Use the RS-232C) and
finally the SET saves data values.
(3) White Balance Adjustment(Manual Adjustment)
¯
Operate Zero Calibration of CA-100 and Sensor must be
stick completely to the surface of LCD module
¯
Devide Manual adjustment into AV/PC and operate
adjustment by the following sequence.
¯
Manual adjustment is a temporary method when automatic
adjustment is not correspondent.
1) Select WHITE PATTERN of HEAT RUN mode by
pressing ‘POWER ON’ key on SVC communicator and
then operate HEAT RUN more than 15 minute
2) Supply pattern signal for W/B adjustment in pattern
generator. (External INPUT)
3) Low Light has no special adjustment.
4) To adjust High Light, stick sensor to 2) pattern(White)
and after select the R - H and G - H by pressing ADJ
button on SVC communicator, press the Vol +/- Key
and adjust it until color coordination becomes.
color coordination : X=0.283±0.025, Y=0.296±0.025
color temperature : 9,300°K ± 1000°K
5) Exit adjustment mode using Enter button.
