Adjustment Instruction - LG RZ-37LZ30 Service Manual

1. Application Object
These instructions are applied to all of the MODELS of LCD TV, ML-
038C.
2. Instruction
2-1. 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.
2-2. Adjustment must be done in the correct order.
But it can be changed in consideration of mass production.
2-3. 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.
2-4. The input voltage of the receiver must keep 220V,60Hz in adjusting.
●Input voltage is possible from 100V to 264V . Adjustment should be
operated in 220V/60Hz if there is no specific designation.
2-5. 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 the adjustment.(Or white condition in HEAT-RUN
mode)
●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
afterimage may be occur in the black level part of the screen.
3. 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
to the LCD Module.)
3-1.White Balance Adjustment
3-1-1. Required Equipment
Color Analyzer ( CA-100 or same production )
3-1-2. Connection Diagram of Equipment for Measuring (Automatic
Adjustment)
High Light
<Fig .1> Connection Diagram of Automatic Adjustment
- Connect RS-232C to Adjustment Equipment and SET.
- Automatization operating room has in charge of managing and repairing
about adjusting equipment.
- Automatic adjustment equipment decides the value 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.

3-1-2. White Balance Adjustment(Manual Adjustment)
● Operate Zero Calibration of CA-100 and Sensor must be stick
completely to the surface of LCD module.
● Divide 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 minutes..
(2) Supply pattern signal for WB adjustment in pattern generator. (External INPUT)
(3) Low Light has no special adjustment.
(4) White Balance Adjustment must be only perform in A/V
mode(A/V3) Thereis no WB Adjustment for RGB input
(5) To adjust High Light, stick sensor to (2) pattern(White), and after select
the R-H G-H by pressing ADJ button on SVC Communicator, press
the Vol +/- Key and adjust it until color coordination becomes (B
GAIN is fixed)
Color coordination : X; 0.290 ± ± 0.025 , Y; 0.284 ± ± 0.025
Color temperature : 9,300。 。 K ± ± 1,000。 。 K.
(6) Exit adjustment mode using Enter button.
3-2. EDID (The Extended Display Identification Data)/DDC(Display Data
Channel) Adjustment
3-2-1. This is a function that is made for the realization of "Plug and
Play" which makes possible to use the user environment right
after reorganization by communicating with monitor automatically.
