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 manufacturer 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
1. Input Selection Circuit
This block is composed of 74LVC257(U5) and peripheral devices.
There are two inputs, 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 AD9883 (U4) and peripheral devices.
AD9883 includes A/D converter, Pre-amp, and PLL.
The Analog RGB signal (0.7Vp-p) is input to R,G,B port of AD9883(U4).
Input signal is amplified, phase locked , A/D converted in 8bits digital signal by this IC(U4), and sent to the Digital
video signal to PW166B-20T.
U4 makes clock for PW166B-20T(U8).
3. TMDS PanelLink Receiver
This Block is composed of SiI161B (U201) and peripheral devices.
This IC decodes PanelLink Digital Input signal(TMDS) from DVI-D Pin (J18) and make 8bit digital RGB signal with
Digital EVEN/ODD format to PW166B-20T(U8).
4. DDC controller
This block is composed of PW166B-20T(U8) and peripheral devices.
PW166B-20T controls peripheral devices through IIC line.
Major functions are (1) to control Flash memory through DDC-SCLA, DDC-SDAA of D-sub And (2) to store EDID
data in the EEPROM (U17, U30)
5. Video Decoder
This block is composed of SAA7114H (U7) and peripheral devices.
PW166B-20T controls this IC through IIC Line.
This IC analyzes input signal of CVBS, Y/C and outputs analyzed signal (8bit interlace signal) to De-interlace block.
Analyzed signal has video control signals like Contrast, Brightness, Sharpness, Color, tint signals Including Adaptive
Comb Filter.
6. Audio Decoder
This block is composed of MSP3420G (U49) and peripheral devices.
PW166B-20T controls this IC through IIC Line.
This IC analyzes Audio input signal through A/V Jack and PC audio.
And output the analyzed signals
7. De-interlace
This block is composed of SDA9400 (U16) and peripheral devices.
PW166B-20T (U8) controls this IC through IIC Line.
And this IC convert 8 Bit Interlaced Y/UV signal to De-interlace signal.
It outputs converted signal to Format Converter (PW166B-20T).
8. Format Converter(Scaler)
This block is composed of PW166B-20T (U8), M29W800DT (U19) and peripheral devices.
MICOM in PW166B-20T (U7) processes outputs of A/D Converter and TMDS Receiver,
De-interlace output and output processed 48 Bit Digital signal to TMDS Transmitter.
PW166B-20T is Format Converter IC that receives Digital signal and outputs proper frame signal to LCD Module
Timing(1280x768,WXGA).
9. PanelLink Circuit
TMDS Transmitter (THC63LVDM83R, U401) is the IC that receives output digital signal of PW166B-20T (U8) and
output to LCD Module.
The signal format is Panel-link.
LCD Module has Panel-link receiver that is same output of PW166B-20T.
This is the best for reduction EMI problem and the number of pin connector.

10. DC/DC Converter block
DC/DC Converters convert the input 12V, 24V to proper 2.5V, 3.3V, 5V, 8V for main control system.
For shooting heat trouble, we use the DC/DC converting IC.
11. Power Supply Block
This Block generates DC Voltages(5V, 12V, 18V and 24V) to Main Control system from AC Power(100-240 V, 50/60
Hz, 1.0 A).
This Circuit contains PFC(Power Factor correction) circuit.
The Minimum of Power efficiency is about 75%.

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.

- Programmable Signal Generator.
(eg. VG-819 made by Astrodesign Co.)
- Oscilloscope.
- White Balance Meter. (CA-110)
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 15.
3) Press Menu key, Vp key, Right key of Remote
controller or Menu Buttons in sequence.
4) Select “WHITE BALANCE ADJUST”and Press SET
key.
5) After “INPUT WHITE PATTERN”message, Display
Color 15, 0 pattern at Mode 15.
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 LM805L 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 LM805L on the IBM
compatible PC.
3) Select EEPROM → Digital EDID write command
and Enter.
4) This will write the Digital EDID data to EEPROM.
