IMPORTANT SAFETY NOTICE
Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by in the Schematic Diagram and Exploded View. 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. Do not modify the original design without permission of manufacturer.
General Guidance Leakage Current Hot Check (See below Figure) Plug the AC cord directly into the AC outlet. An isolation Transformer should always be used during the servicing of a receiver whose chassis is not isolated from the AC Do not use a line Isolation Transformer during this check. power line.

Any voltage measured must not exceed 0.75 volt RMS which is corresponds to If any fuse (or Fusible Resistor) in this TV receiver is blown, 0.5 mA. replace it with the specified. In case any measurement is out of the limits specified, there is possibility of shock hazard and the set must be checked and When replacing a high wattage resistor (Oxide Metal Film Resistor, repaired before it is returned to the customer. over 1 W), keep the resistor 10 mm away from PCB. Leakage Current Hot Check circuit Keep wires away from high voltage or high temperature parts.
Before returning the receiver to the customer, always perform an AC leakage current check on the exposed metallic parts of the cabinet, such as antennas, terminals, etc., to be sure the set is safe to operate without damage of electrical shock.
Leakage Current Cold Check(Antenna Cold Check) With 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. If the exposed metallic part has a return path to the chassis, the measured resistance should be between 1 MΩ and 5.2 MΩ. When the exposed metal has no return path to the chassis the reading must be infinite. An other abnormality exists that must be corrected before the receiver is returned to the customer.
