Service should not be attempted by anyone unfamiliar with the necessary precaution on

thisreceiver. The following are the necessary precautions to be observed before servicing this

chassis.

1. When replacing a chassis in the cabinet, always be certain that all the protective devices are

put back in place, such as: non-metallic control knobs, insulating covers, shields,

isolation resistor-capacitor network etc.

2. When replacing parts or circuit boards, disconnect the power cord.

3. When replacing a high wattage resistor (oxide metal film resistor) on the circuit board, keep

the resistor 10mm (1/2in) away from circuit board.

4. Connection wires must be kept away from components with high voltage or high temperature.

5. If any fuse in this TV receiver is blown, replace it with the FUSE specified in the chassis parts

list.

PRODUCT SAFETY NOTICE

These characteristics are often passed unnoticed by a visual inspection.

Replacement parts which have these special safety characteristics are identified in this manual

and its supplement electrical components having such features are shaded on the schematic

diagram and the parts list.

Before replacing any of these components, read the parts list in this manual carefully. The use of

substitute replacement parts which do not have the same characteristic as specified in the parts

list may create shock, fire or other hazards.

CAUTION: BEFORE SERVICING THE CHASSIS, READ THE “SAFETY
