WARNING FOR THE SAFETY-RELATED COMPONENT.
• There are some special components used in LCD
monitor that are important for safety. These parts are
marked on the schematic diagram and the
replacement parts list. It is essential that these critical
parts should be replaced with the manufacturer’s
specified parts to prevent electric shock, fire or other
hazard.
• Do not modify original design without obtaining written
permission from manufacture or you will void the
original parts and labor guarantee.
TAKE CARE DURING HANDLING THE LCD MODULE
WITH BACKLIGHT UNIT.
• Must mount the module using mounting holes arranged
in four corners.
• Do not press on the panel, edge of the frame strongly
or electric shock as this will result in damage to the
screen.
• Do not scratch or press on the panel with any sharp
objects, such as pencil or pen as this may result in
damage to the panel.
• Protect the module from the ESD as it may damage the
electronic circuit (C-MOS).
• Make certain that treatment person’s body are
grounded through wrist band.
• Do not leave the module in high temperature and in
areas of high humidity for a long time.
• The module not be exposed to the direct sunlight.
• Avoid contact with water as it may a short circuit within
the module.
• If the surface of panel become dirty, please wipe it off
with a softmaterial. (Cleaning with a dirty or rough cloth
may damage the panel.)
WARNING
BE CAREFUL ELECTRIC SHOCK !
• If you want to replace with the new backlight (CCFL) or
inverter circuit, must disconnect the AC adapter
because high voltage appears at inverter circuit about
650Vrms.
• Handle with care wires or connectors of the inverter
circuit. If the wires are pressed cause short and may
burn or take fire.
PRECAUTION
CAUTION
Please use only a plastic screwdriver to protect yourself
from shock hazard during service operation.

DESCRIPTION OF BLOCK DIAGRAM
- 15 -
1. Input Selection Circuit
This block is composed of 74LVC257 and peripheral devices.
There are two input, Analog and Digital H/V Sync. LVC257 IC chooses one input and outputs selected input through
sync selection pin (Pin 1).
2. A/D Converter
This block is composed of two AD9884 (U1,U2) and passive devices.
The basic RGB signal (0.7Vp-p)is input to U1 through C133, C134, C135 pin.
But RGB signal is input to U2 through C75, C76, C77 in the case of UXGA.
Input video signal is amplified, Phase locked, A/D converted in this IC.
And send the Digital video signal to PW364A.
3. TMDS Receiver
This Block is composed of SiI161A (U201) and Peripheral devices.
This IC decodes CompositeInput signal from DVI-D Pin (J18) and make 8bit digital signal to send Digital signal to
PW364.
4. Video Decoder
This block is composed of VPC3230D (U48) and peripheral devices.
PW364A controls this IC through IIC Line. This IC analyzes input signal of CVBS, Y/C and output analyzed signal(8bit
interlace signal) to De-interlaceblock.
Analyzed signal has video control signals like Contrast, Brightness, Sharpness, Color, tint signals.
5. De-interlace
This block is composed of gmVLX1A (U41), gmAFMC (U69), SGRAM (U42) and peripheral devices.
PW364A(U7) controls this IC and this IC convert 8 Bit Y/UV signal to De-interlace signal.
It output converted signal to Format Converter.
6. Format Converter
This block is composed of PW364A (U7), M29W800AT (U9) and passive devices.
Micom in PW364A(Scaler)(U7) processes A/D Converter output, output of TMDS Receiver,
De-interlace output and output processed 48 Bit Digital signal to TMDS Transmitter.
PW364A is Format Converter IC that receive Digital signal and output proper frame signal to LCD Module
(1600x1024).
7. Panel-Link Circuit
TMDS Transmitter(U38) is the IC that receives output digital signal of PW364A(U7) and output
composite signal to LCD Module.
Composite signal is the standard format for LCD Panel.
8. DC/DC Converter block
DC/DC Converters convert the input 15V to proper 2.5V, 3.3V, 5V for main board.
For shooting heat trouble, we use the DC/DC converting IC.

ADJUSTMENT
- 16 -
Figure 1. Cable Connection
All adjustment are thoroughly checked and corrected
when the monitor leaves the factory, but sometimes
several minor adjustment may be required.
Adjustment should be following procedure and after
warming up for a minimum of 30 minutes.
•Alignment appliances and tools.
- IBM compatible PC
- Programmable Signal Generator.
(eg. VG-819 made by Astrodesign Co.)
- Oscilloscope.
- White Balance Meter
1. Adjustment for Factory Preset Mode
No read to adjust FOS data for Factory Preset Mode.
2. Adjustment for White Balance
1) Set External Bright to MAX position and Contrast to
MAX position.
2) Display Color 0,0 pattern at Mode 8.
3) Press Menu key, 2 key, 9 key, 5 key of Remote
controller in sequence.
4) Select “WHITE BALANCE ADJUST”and Press SET
key.
5) After “INPUT WHITE PATTERN”message, Display
Color 15, 0 pattern at Mode 8.
6) No attempt to manually adjust, BIAS and Drive data
is automatically adjustde and saved to the EEPROM.
7) After “OK”message, Press SET KEY.
8) Select “SERVICE MODE EXIT”and Press SET KEY.
3. DDC Data Write Procedure-Analog
1) Use this procedure only when there is some
problem on Analog EDID data.
2) Run alignment program for LM295B on the IBM
compatible PC.
3) Select EEPROM → Analog EDID write command
and Enter.
4) This will write the Analog EDID data to EEPROM.
4. DDC Data Write Procedure-Digital
1) Use this procedure only when there is some
problem on Digital EDID data.
2) Run alignment program for LM295B on the IBM
compatible PC.
3) Select EEPROM → Digital EDID write command
and Enter.
4) This will write the Digital EDID data to EEPROM.
