Belinea 101750/101751 Service Manual First editior September 2003 Service Manual 3 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. For continued safety, do not attempt to modify the circuit board. 2. Disconnect the AC power ,Signal cable and Stereo cable before servicing. 1-1-2 Servicing the LCD Monitor 1. When servicing the LCD Monitor Disconnect the AC power cord from the AC outlet. 2. 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. 2. Inspect all protective devices such as nonmetallic control knobs, insulating materials, cabinet backs, adjustment and compartment covers or shields, isolation resistor-capacitor networks, mechanical insulators, etc. 3. To be sure that no shock hazard exists, check for leakage current in the following manner. Warning : Do not use an isolation transformer during this test. a. Plug the AC line cord directly into a 120 Volt AC outlet. b. Unisg two clip leads, connect 1.5 , 10 watt resistor paralleled by a 0.15 capacitor in series with an exposed metal cabinet part and a known earth ground, such as an electrical conduit or electrical ground connected to an earth ground. 4 Service Manual Precautions c. Use a SSVM or VOM with 1000 ohms per-volt or higher sensitivity to measure the AC voltage drop across the resistor (see Figure 1-1). d. Connect the resistor to an exposed metal part having a return path to the chassis(metal cabinet, screw heads, knobs, shafts, escutcheon, etc.) and measure the AC voltage dr
