There are some special components used in LCDmonitor that are important for safety. These parts aremarked on the schematic diagram and thereplacement parts list. t 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 cert ai n t hat treat ment 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. f the surface of panel become dirty, please wipe it offwith a softmaterial. (Cleaning with a dirty or rough clothmay damage the panel.)WARNINGBE CAREFUL ELECTRC SHOCK ! f you want to replace with the new backlight (CCFL) orinverter circui t, must di sconnect the AC adapterbecause high voltage appears at inverter circuit about650Vrms. Handle with care wires or connectors of the invertercircuit. f the wires are pressed cause short and mayburn or take fire.PRECAUTIONCAUTIONPlease use only a plastic screwdriver to protect yourselffrom shock hazard during service operation.TIMING CHART- 4 -VDEOSYNCBDCFEA>H + 31.469 800 640 16 96 48V 70.8Hz 449 350 37 2 60H 31.469 840 640 16 96 48V 59.94 525 480 10 2 33H 37.5 840 640 16 64 120V 75 500 480 1 3 16H 31.468 900 720 18 108 54V + 70.09 449 400 12 2 35H + 37.879 1056 800 40 128 88V + 60.317 628 600 1 4 23H + 46.875 1056 800 16 80 160V + 75.0 625 600 1 3 21H +/ 49.725 1152 832 32 64 224V +/ 74.55 667 624 1 3 39H 48.363 1344 1024 24 136 160V 60.0 806 768 3 6 29H 60.123 1312 1024 16 96 176V 75.029 800 768 1 3 28H +/ 68.681 1456 1152 32 128 144V +/ 75.062 915 870 3 3 39H +/ 61.805 1504 1152 18 134 200V +/ 65.96 937 900 2 4 31H + 63.981 1688 1280 48 112 248V + 60.02 1066 1024 1 3 38H + 79.976 1688 1280 16 144 248V + 75.035 1066 1024 1 3 38ModeH/VSort1234567891011121325.17528.32125.17531.540.049.557.28365.078.75100.092.978108.0135.0640x35070Hz640x48060Hz640x48075Hz720x40070Hz800x60060Hz800x60075Hz832x62475Hz1024x76860Hz1024x76875Hz1152x87075Hz1152x90065Hz1280x102460Hz1280x102475HzSyncPoIarityFrequencyDotClockTotaI Period(E)Video Act ive Time(A)Sync Duration(D)Back Porch(F)Front Porch(C)ResoIution- 5 -FRONT VIEWFront ControI PaneI REAR VIEWOPERATING INSTRUCTIONSSee Front Control PanelPower Connect2 1 3 4 6 51.

Video ControIIer Part & DispIay Data Transmitter Part.This part amplifies the level of video signal for the digital conversion and converts from the analog video signal to thedigital 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 135MHz.This part consists of the Scaler, Flash-ROM C which stores program data, Reset C.The Scaler gets the video signal converted analog to digital, interpolates input to 1280 x 1024 resolution signal andoutputs 8-bit R, G, B signal to transmitter.Especially pre-amp / ADC / Video controller/ Transmitter are merged to one chip 'Gm2121' by Genesis.This part transmit digital signal from the Scaler to the receiver of module.2. Power PartThis part consists of the one 3.3V and one 2.5 regulators to convert power which is provided 5V in LPS Board.5V is provided for LCD Panel.Also, 5V is converted 3.3V and 2.5V by regulator. Converted power is provided for C in the main board.- 10 -EMICOMPONENTSLINE100 ~ 240VINPUT RECTIFIERAND FILTERENERGYTRANSFEROUTPUT RECTIFIERAND FILTER12V5VGNDSIGNALCOLLENTIONPHOTO-COUPLERISOLATIONPWMCONTROLCIRCUITHVDC100KHzPRIMARY SECONDARY50 ~ 60HzINVERTER CIRCUIT12VHigh VoItage outputOperation description_LIPSLIPS Board BIock Diagram1.
