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 LG 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
- 11 -
1. Scaler One chip IC(GMZAN1, U3)
GMZAN1 (U3) is one chip IC which it supports four internal function blocks of Video Amp, PLL, A/D converter and
Video processor.
Video signal (0.7Vp.p) clamped through C44, 45, 191 with matching IC’s proper cut off voltage.
This signal is processed as a proper 8 bit digital signal by U3’s amplifying, phase locking, A/D converting, and scaling
operations.
U3 generates Clock, Horizontal and Vertical sync, Data Enable signals as LCD Panel’s input signals.
2. System Controller (Microprocessor) Circuit
1) Microprocessor (U4) distinguishes polarity and frequency by calculating horizontal and vertical sync input
from signal source.
2) Microprocessor (U4) carries out power control by sending power-down trigger signal to each IC.
3) Microprocessor (U4) communicates with EEPROM (U1), and GMZAN1 (U3)
through IIC(2 lines) or 6 bit bus line. It makes all devices operated properly.
4) Microprocessor (U4) let User adjust screen by OSD function.
3. DC/ DC Converter
This circuit supplies DC power for each device needing DC voltage of 3.3VD, 3.3V_AD, 3.3V_PL, Module Power 3.3V
and 5VS.
L4973D5.1(U13) , the DC/DC controller IC converts input 12Vdc into 5VS and 3.3Vdc with peripheral circuit
composed of Inductor (L11), condensing components (ZD5, C72), and Regulators(U2, U7, U24,U30).
MODPWR(3.3V) for LCD module power is switched by U12, switching FET, controlled by Microprocessor.
3.3VD, 3.3V_AD, and 3.3V_PL for GMZAN1 (U3) and 3.3V for LVDS (U9) are switched by U5, switching FET,
controlled by Microprocessor for Power saving.
4. Display Data Transmitter Part (LVDS).
This part transmit digital signal from the Scaler to the receiver of module.

3) PRESET START command and Enter.
4) BIAS CAL command and Enter.
5) No attempt to manually adjust, BIAS data is auto-
matically adjusted and saved to the EEPROM.
6) Display color 15,0 pattern at Mode 12.
7) Select DRIVE CAL command and Enter.
8) Color 1 (9300K) and Color 2 (6500K) are
automatically adjusted and saved to the EEPROM.
9) Select PRESET EXIT command and Enter.
3. DDC Data Write Procedure
1) Use this procedure only when there is some
probelm on EDID data.
2) Select EEPROM →EDID Write command and
Enter.
3) This will write the EDID data to EEPROM.
