CAUTION: BEFORE SERVICING THE CHASSIS, READ THE "SAFETY
PRECAUTION" "PRODUCT SAFETY NOTICE"ON PAGE 1 OF THIS
MANUAL.
SAFETY PRECAUTION
WARNING:
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
Many electrical and mechanical parts in the chassis have special safety-related characteristics.
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.
