PRECAUTION

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 manufacturers 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.

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.
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 persons 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.)

Please use only a plastic screwdriver to protect yourself from shock hazard during service operation.

DESCRIPTION OF BLOCK DIAGRAM
1. Scaler One chip IC(GMZAN2, U201) GMZAN2 (U201) 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 C209, 208, 207 with matching ICs proper cut off voltage. This signal is processed as a proper 8 bit digital signal by U201s amplifying, phase locking, A/D converting, and scaling operations. U3 generates Clock, Horizontal and Vertical sync, Data Enable signals as LCD Panels input signals. 2. System Controller (Microprocessor) Circuit. 1) Microprocessor (U501) distinguishes polarity and frequency by calculating horizontal and vertical sync input from signal source. 2) Microprocessor (U501) carries out power control by sending power-down trigger signal to each IC. 3) Microprocessor (U501) communicates with EEPROM (U502), and GMZAN2 (U201) through IIC(2 lines) or 6 bit bus line. It makes all devices operated properly. 4) Microprocessor (U501) 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. L4978(U801) , the DC/DC controller IC converts input 12Vdc into 5VS and 3.3Vdc, 2.5Vdc with peripheral circuit composed of condensing components (ZD801, C810), and Regulators(U802,U805). MODPWR(3.3V) for LCD module power is Regulator by U805, Regulator, controlled by Microprocessor. 3.3VD, 3.3V_AD, and 3.3V_PL for GMZAN2 (U201) and 3.3V for LVDS (U401) are switched by U804, 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. 5. Audio Part (TDA7449,TDA7496L) In This Circuit, Audio Processor(TDA7449) Which is Controlled by Microprocessor(U501) adjust volume/treble/bass/balance of Audio signal which come from PC. The Signal come from TDA7449 is amplified by TDA7496L. The final output signal is output through speaker.

ADJUSTMENT

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 10 minutes. Alignment appliances and tools. - IBM Compatible PC - Programmable Signal Generator. (eg. VG-819 made by Astrodesign Co.) - E(E)PROM with each mode data saved. - Alignment Adapter and Software. 1. Adjustment for Factory Preset Mode 1) Run alignment program for LM568E on the IBM compatible PC. 2) Display cross hatch pattern at Mode 1. 3) Select EEPROM ALL Init command and Enter. 4) Press "Y" key, it will automatically save all FOS data to EEPROM. 2. Adjustment for White Balance 1) Display color 0,0 pattern at Mode 12. 2) Set External Bright to MAX position and Contrast to MAX Position. 3) Select PRESET START BIAS CAL command and Enter. 4) No attempt to manually adjust, BIAS data is automatically adjusted and saved to the EEPROM. 5) Display color 15,0 pattern at Mode 12. 6) Select DRIVE CAL command and Enter. 7) Color 1 (9300K) and Color 2 (6500K) are automatically adjusted and saved to the EEPROM. 8) 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.
