Important Safety Notice
Special components are used in this television set which are important for safety. These parts are identified on the
schematic diagram by the symbol and printed in BOLD TYPE on the replacement part list. It is essential that
these critical parts are replaced with the manufacturer's specified replacement part to prevent X-ray radiation, shock,
fire or other hazards. Do not modify the original design without the manufacturer's permission.
Safety Precautions
General Guidelines
An Isolation Transformer should always be used Measure the resistance between the jumpered AC plug
during the servicing of a receiver whose chassis is not and expose metallic parts such as screwheads, antenna
isolated from AC power line. Use a transformer of terminals, control shafts, etc. If the exposed metallic

When servicing, observe the original lead dress, Plug the AC cord directly into the AC outlet. Do not use
