SAFETY PRECAUTIONS
IMPORTANT SAFETY NOTICE
Many electrical identify these parts and mechanical parts in this chassis have special
safety-related characteristics!
In the Schematic Diagram and Replacement Parts List.
It is essential that these special safety parts should be replaced with the same
components as recommended in this manual to prevent X-RADIATION, Shock, Fire,
or other Hazards.
Do not modify the original design without permission of the manufacturer.
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. Use a transformer of adequate
power rating as this protects the technician from accidents that might result in
personal injury caused by electrical shocks.
It will also protect the receiver and it’s components from being damaged by
accidental shorts of the circuitry that might be inadvertently introduced during the
service operation.
If any fuse (or Fusible Resistor) in this TV receiver is blown, replace it with a specified
one.
When replacing a high wattage resistor (Oxide Metal Film Resistor, over 1W), keep
