WARNING FOR THE SAFETY-RELATED COMPONENT.
• There are some special components used in LCDmonitor that are important for safety. These parts aremarked on the schematic diagram and thereplacement parts list. It is essential that these criticalparts should be replaced with the manufacturer’sspecified parts to prevent electric shock, fire or otherhazard.
• Do not modify original design without obtaining writtenpermission from manufacturer or you will void theoriginal parts and labor guarantee.
TAKE CARE DURING HANDLING THE LCD MODULEWITH BACKLIGHT UNIT.
• Must mount the module using mounting holes arrangedin four corners.
• Do not press on the panel, edge of the frame stronglyor electric shock as this will result in damage to thescreen.
• Do not scratch or press on the panel with any sharpobjects, such as pencil or pen as this may result indamage to the panel.
• Protect the module from the ESD as it may damage theelectronic circuit (C-MOS).
• Make certain that treatment person ’s body aregrounded through wrist band.
• Do not leave the module in high temperature and inareas 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 withinthe module.
• If the surface of panel become dirty, please wipe it offwith a softmaterial. (Cleaning with a dirty or rough clothmay damage the panel.)
WARNING
BE CAREFUL ELECTRIC SHOCK !
• If you want to replace with the new backlight (CCFL) orinverter circuit, must disconnect the AC adapterbecause high voltage appears at inverter circuit about650Vrms.
• Handle with care wires or connectors of the invertercircuit. If the wires are pressed cause short and mayburn or take fire.
PRECAUTION
CAUTIONPlease use only a plastic screwdriver to protect yourselffrom shock hazard during service operation.

DESCRIPTION OF BLOCK DIAGRAM
1. Input Signal Part
It is composed of four parts.-PC signal input part:24pin DVI-I and PC Audio inputjack.-AV Video input part: RCA Jack (CVBS signal), S-VideoJack-HDTV input part : YPbPr Jack and RL Stereo Audioinput jack-TV signal input part: TV Tuner input Connector (TVsignal)
2. Video Signal Processor
It is composed of GM1501(U402) GM1501 includes A/D Converter and LVDS Transmitter GM1501 is directly Inputted Analog and Digital Signalor Video Signal from Video DecoderThis Signal is converted into compatible Signal byMICOM's control and then GM1501 transmit it to LCDModule.
3. Analog Switch
It is composed of BA7657FBA7657F Switch DVI-A to HDTV
4. Micom Controller
It is composed of 29LV040B(U403) its functions iscontrolling each IC, display mode and frequencythrough EEPROM and IIC communication.
5. Video decoder.
This block is composed of VPC3230D (U203) andperipheral devices.This IC analyzes input signal of CVBS, Y/C and outputanalyzed signal (8bit interlace signal) to Video SignalProcessor block.Analyzed signal has video control signals like Contrast,Brightness, Sharpness, Color, tint signals IncludingAdaptive Comb Filter.
6. Audio decoder part.
This block is composed of MSP3420G (U503) andperipheral devices.This IC analyzes Audio input signal through A/V Jackand PC audio. And output the analyzed signals to Audio Amplifier(TPA3004).
7. Audio Amplifier
This block is composed of TPA3004 (U505) andperipheral devices.It amplifies audio signal input from Audio Decoder and output amplified audio signal to Speaker, Audio OutputJack.
8. Control
It receives outer key input, transmits the input toMicom(U403).There is key input part and remote controller receiver.
9. LIPS Part
It is composed of two parts- Power Part functions that Input power converts to 33V,12V,5V power for operating circuits.
- Inverter Part functions that Input Power converts to compatible "Vrms" value for operate LCD lamp.
