Safety Precautions
The following precautions must be observed.
1: Comply with all caution and safety-related notes provided on the cabinet back, cabinet bottom, inside the
cabinet or on the chassis.
2: When replacing a chassis in the cabinet, always be certain that all the protective devices are installed
properly, such as, control knobs, adjustment covers or shields, barriers, etc..
DO NOT OPERATE THIS TELEVISION WITHOUT THE PROTECTIVE SHIELD IN POSITION AND PROPERLY
SECURED.
3: Before replacing the cabinet cover, thoroughly inspect the inside of the cabinet to see that no stray parts or
tools have been left inside.
Before returning any television to the customer, the service personnel must be sure that it is completely safe to
operate without danger of electrical shock.
Product Safety Notice
Product safety should be considered when a component replacement is made in any area of a receiver.
Components indicated by mark in the parts list and the schematic diagram designate components in which
safety can be of special significance. It is particularly recommended that only parts designated on the parts list
in this manual be used for component replacement designated by mark . No deviations from resistance
wattage or voltage ratings may be made for replacement items designated by mark .
