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 the circuit board. 2. Disconnect the AC power and DC power jack before servicing. 1-1-2. Servicing the LED TV 1. When servicing the LED 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 LED 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 LED TV. 2. Inspect all protective devices such as nonmetallic control knobs, insulating materials, cabinet backs, adjustment and compartment covers or shields, isolation resistorcapacitor 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). (READING SHOULD) NOT BE ABOVE 0.5mA LEAKAGE DEVICE CURRENT UNDER TESTER TEST TEST ALL
