SAFETY PRECAUTIONS
1. An isolation transformer should be used to supply power to the TV during servicing
on the primary of the converter transformer of the set.
2.
Read and comply with all caution and safety related notes on the back cover,inside
the TV, on the PCBs and the picture tube.
3. When replacing a chassis in the cabinet, always be certain that all the protective
devices are installed properly (e.g. control knobs, adjustment covers or shields,
barriers, isolation resistor-capacitor networks etc.). Before returning the television
to the customer, the service technician must ensure that it is completely safe to
operate.
The primary source of X-RADIATION in 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. Refer to this service manual on the high voltage adjustment for the
specific high voltage limit.If high voltage exceeds the limits, take necessary corrective
action.Carefully follow the instructions for +B volt power supply adjustment, and high
voltage check to maintain the high voltage within the specified limits.
Maintenance and repair of this TV should be done by qualified service personnel only
when servicing the high voltage system, remove static charge from it by discharging
the picture tube (2nd anode lead) to the dag coating (picture tube grounding lead).
