1. Precautions 1. Precautions 1-1. Safety Precautions Follow these safety, servicing, and ESD precautions to prevent damage and to protect against potential hazards such as electrical shock. 1-1-1. Warnings 1. For continued safety, do not attempt to modify any circuitry. 1-1-2. Servicing the LCD TV 1. When servicing the LCD TV, Disconnect the AC line 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 LCD TV 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 LCD TV. 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. Leakage Current Hot Check (Figure 1-1): WARNING : Do not use an isolation transformer during this test. Use a leakage current tester or a metering system that complies with American National Standards Institute (ANSI C101.1, Leakage Current for Appliances), and Underwriters Laboratories (UL Publication UL1410, 59.7). 4. With the unit completely reassembled, plug the AC line cord directly into a 120V AC outlet. With the unit's AC switch (READING SHOULD) NOT BE ABOVE 0.5mA LEAKAGE DEVICE CURRENT UNDER TESTER TEST TEST ALL EXPOSED METAL SURFACES 2-WIRE CORD *ALSO TEST WITH PLUG REVERSED (USING AC ADAPTER PLUG AS REQUIRED) EARTH GROUND Figure 1-1. Leakage Current Test Circuit first in the ON position and then OFF, measure the current between a known earth ground (metal water pipe, conduit, etc.) and all exposed metal parts, including: metal cabinets, screwheads and control shafts. The current measured should not exceed 0.5 milliamp. Reverse the power-plug prongs in the AC outlet and repeat the test. 1-1-4. Product Safety Notices Some electrical and mechanical parts have special safety related characteristics which are often not evident from visual inspection. The protection they give may not be obtained by replacing them with components rated for higher voltage, wattage, etc. Parts that have special safety characteristics are identified by on schema
