SERVICE SAFETY AND MAINTENANCE
WARNING :
BEFORE EXAMINING AND SERVICING
THIS CHASSIS READ CAREFULLY THE
FOLLOWING SAFETY
INSTRUCTIONS.
X-RAY RADIATION PRECAUTION
1.
The EHT must be checked every time the TV is serviced to ensure that the CRT does
not emit X-ray radiation as result of excessive EHT voltage. The maximum EHT voltage
permissible in any operating circumstances must not exceed the rated value. When
checking the EHT, use the High Voltage Check procedure in this manual using an
accurate EHT voltmeter.
2.
The only source of X-RAY radiation in this TV is the CRT. The TV minimizes X-RAY
radiation, which ensures safety during normal operation. To prevent X-ray radiation,
the replacement CRT must be identical to the original fitted as specified in the parts list.
3.
Some components used in this TV have safety related characteristics preventing the
CRT from emitting X-ray radiation. For continued safety, replacement component
should be made after referring the PRODUCT SAFETY NOTICE below.
4.
Service and adjustment of the TV may result in changes in the nominal EHT voltage of
the CRT anode. So ensure that the maximum EHT voltage does not exceed the rated
value after service and adjustment.
