These parts are identified by  in the Exploded View.  \nIt 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.  \nDo not modify the original design without permission of manufacturer.  \nGeneral Guidance  \nAn isolation Transformer should always be used during the servicing of a receiver whose chassis is not isolated from the AC power line. Use a transformer of adequate power rating as this protects the technician from accidents resulting in personal injury from electrical shocks.  \nIt 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.  \nIf any fuse (or Fusible Resistor) in this TV receiver is blown, replace it with the specified.  \nWhen replacing a high wattage resistor (Oxide Metal Film Resistor, over 1 W), keep the resistor 10 mm away from PCB.  \nKeep wires away from high voltage or high temperature parts.  \nBefore returning the receiver to the customer,  \nalways perform an AC leakage current check on the exposed metallic parts of the cabinet, such as antennas, terminals, etc. , tobe sure the set is safe to operate without damage of electrical shock.  \nLeakage Current Cold Check(Antenna Cold Check)  \nWith the instrument AC plug removed from AC source, connect an electrical jumper across the two AC plug prongs. Place the AC switch in the on position, connect one lead of ohm-meter to the AC plug prongs tied together and touch other ohm-meter lead in turn to each exposed metallic parts such as antenna terminals, phone jacks, etc.  \nIf the exposed metallic part has a return path to the chassis, the measured resistance should be between 1 MΩ and 5.2 MΩ .  \nWhen the exposed metal has no return path to the chassis the reading must be infinite.  \nAn other abnormality exists that must be corrected before the receiver is returned to the customer.  \nLeakage Current Hot Check (See below Figure)  \nPlug the AC cord directly into the AC ","cbCaivvgRCr4gJa4","https://ap.wps.com/l/cbCaivvgRCr4gJa4","pdf",12998078,89,"English","# Contents\n## Safety Precautions\n## Servicing Precautions\n## Specification\n## Software Update\n## Block Diagram\n## Exploded View\n## Disassembly Guide\n## Troubleshooting Guide","[{\"question\":\"What must be done before servicing this chassis (EA82B)?\",\"answer\":\"Read and follow the safety precautions in the manual before servicing the receivers covered by it.\"},{\"question\":\"How are safety-critical parts identified and replaced?\",\"answer\":\"Safety-related components are identified in the exploded view and must be replaced with the same recommended components to prevent shock, fire, or other hazards.\"},{\"question\":\"What procedure is used to verify leakage current on exposed metallic parts?\",\"answer\":\"Perform an AC leakage current check on exposed metallic parts such as antennas and terminals, using the specified cold and hot check methods and ensuring the measured limits are not exceeded.\"}]","OLED TV Service Manual - Chassis EA82B | PDF",1792789157,224]
