When the AD board is in DPMS state: 1.1 The IP has been designed so that it operates with a power consumption of less than 0.6W of. 1.2 The Scaler consumes power up to 37mA 1.3 The power to the panel is switched off 2. When the AD board is operating normally: 2.1 The maximum power consumption of the panel lamps is described below (It may vary depending on the panel manufacturer) 17" : 4*(7.0mA*650Vrms)=4* 4.55W=18.2W 2.2 The power consumption of the Panel Control board is as follows: 5V*645mA=3.23W 2.3 The power consumption of the Scaler is as follows: 3.3V*204mA + 1.8V*145mA = 0.93W 13-1 13 Circuit Descriptions 13-1-2 Main board Parts 1. Inverter: A conversion device that converts DC rated voltage/current to high ones necessary for the panel lamp. 2. DC/DC(Regulator): General term for DC to DC converting devices.

1_precaution.pdf1 Precautions 1 Precautions Follow these safety, servicing and ESD precautions to prevent damage and to protect against potential hazards such as electrical shock. 1-1 Safety Precautions 1-1-1 Warnings 1. 2. For continued safety, do not attempt to modify the circuit board. Disconnect the AC power and DC power jack before servicing. 1-1-2 Servicing the LCD Monitor 1. 2. When servicing the LCD Monitor, Disconnect the AC line cord from the AC outlet. It is essential that service technicians have an accurate voltage meter available at all times. Check the calibration of this meter periodically. 1-1-3 Fire and Shock Hazard Before returning the monitor to the user, perform the following safety checks: 1. Inspect each lead dress to make certain that the leads are not pinched or that hardware is not lodged between the chassis and other metal parts in the monitor. Inspect all protective devices such as nonmetallic control knobs, insulating materials, cabinet backs, adjustment and compartmen

4_troubleshooting.pdf4 Troubleshooting 4 Troubleshooting 4-1 Common Acknowledge - If you change the interface board, be sure that the U105, U106 and U103 these three components also changed to the new I/F board because there was program inside. If not, please re-write EDID or upload firmware into Flash memory via VGA Cable. - If you adjust clock and phase, please do it at the condition of Windows shut down pattern. - If you confirm the R.G.B. color is normal or not, please do it under 16-grey scalar pattern. - This LCM is analog interface. So if the entire screen is an abnormal color that means the problem happen in the analog circuit part, if only some scale appears abnormal color that stand the problem happen in the digital circuit part. - If you check the H/V position, please use the crosshatch pattern. - This LCM support more than 30 timing modes, if the input timing mode is out of specification, the picture may appears abnormally. - If brightness uneven, repairs Inverter circuit or change a new panel
