1. SAFETY INSTRUCTIONS.
In order to understand correctly this service manual, it should be read along with schematic diagram of model under
study.
All circuits from this chassis, with exception of primary side of power supply, are isolated from mains.
1.1 Warning.
An isolation transformer should be connected in the power line between the receiver and mains when a service is
performed on the primary side of power supply. The deflection heat sink is connected to 12v.
1.2 Precautions 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. Carefully, follow the instructions for +B1 volt power
supply adjustment and high voltage adjustment to maintain the high voltage within the specified limits.
1.3 Recommendations to protect our environment.
STAND-BY MODE: In order to save energy and to maintain an optimum picture quality, it is advisable to switch off
the TV using the ON/OFF button located at the front of TV set.

RECOMMENDATION ABOUT THE END-OF-LIFE: Your SANYO TV set has been designed and manufactured
using high quality materials which can be recycled and reused. In the future, when the life cycle of this set comes to
