When replacing a high wattage resistor (Oxide Metal Film Resistor, over 1 W), keep the resistor 10 mm away from PCB. If any fuse (or Fusible Resistor) in this TV receiver is blown, replace it with the specified. It will also protect the receiver and it's components from being damaged by accidental shorts of the circuitry that may be inadvertently introduced during the service operation. Use a transformer of adequate power rating as this protects the technician from accidents resulting in personal injury from electrical shocks. General Guidance An isolation Transformer should always be used during the servicing of a receiver whose chassis is not isolated from the AC power line. Do not modify the original design without permission of manufacturer.
It is essential that these special safety parts should be replaced with the same components as recommended in this manual to prevent Shock, Fire, or other Hazards. These parts are identified by in the Schematic Diagram and Exploded View. Only for training and service purposes Many electrical and mechanical parts in this chassis have special safety-related characteristics. 3 - LGE Internal Use Only Copyright © LG Electronics.
