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 Gate Way. 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 signal switching part.
There are two inputs which are analog and digital input.
They come from each 15 pin D-Sub and 24 pin DVI-D connector.
2. Pre-amp/ ADC / PLL / Video Controller.
This part amplifies the level of video signal for the digital conversion and converts from the analog video signal
to the digital video signal using a pixel clock.
The pixel clock for each mode is generated by the PLL.
The range of the pixel clock is from 25MHz to 78.75MHz.
The Scaler gets the video signal converted analog to digital, interpolates input to 1024 X 768 resolution signal
and outputs 8-bit R, G, B signal to LCD module.
Especially pre-amp / ADC / Video controller are merged to one chip ‘Gm5010’ by Genesis.
3. Power Part.
This part consists of the DC/DC converter and two 3.3V and one 2.5 regulators .
The DC/DC converter coverts 12V to be entered power adapter to 5V. 5V, output of DC/DC converter, is
supplied to the Micom and 3.3V/2.5V regulators.
The output voltage of 3.3V / 2.5V regulators flow to IC of each part.
4. MICOM Part.
This part consists of EEPROM IC which stores control data, Reset IC and the Micom.
The Micom distinguishes polarity and frequency of the H/V sync are supplied from signal cable.
The controlled data of each modes is stored in EEPROM.
5. Inverter
The inverter converts from DC12V to AC 700V and operate back-light lamp of module.
