1. Safety instructions
Read this page before doing any operation of adjustment, maintenance or repair the TV set described.
Only skilled personnel of Sanyo Technical Service should do the adjustment, maintenance or repair of TV set.
2. WARNING
For the correct and safe use of the TV set, it is essential that the service personnel follow the process of safety
generally accepted and the safety precautions specified in this manual.
An isolation transformer should be connected in the power line between the receiver and the AC line when a service
is performed on the primary side of the converter transformer of the set.
3. Precaution against X-Rays
The primary source of X-RADIATION in the television receiver is the picture tube. The picture tube is specially
constructed to limit X-RADIATION emissions. For continued X-RADIATION protection, the replacement tube must
be the same type as the original including suffix letter. Excessive high voltage may produce potentially hazardous X-
RADIATION. To avoid such hazards, the high voltage must be maintained within specified limit. If high voltage
exceeds specified limits, take necessary corrective action. Follow the instructions carefully for +B1 volt power supply
adjustment, and high voltage adjustment to maintain the high voltage within the specified limits.
COMPLIANCE TO STANDARDS
All of those marked with
! or
must be
replaced with original parts
WARNING! This TV set contains components which
are particularly sensitive to static electricity (ESD).
It is recommended that all due precaution be taken
