1.4. X-Radiation
Warning:
The potential sources of X-Radiation in TV set are the EHT section and the picture tube. When using a picture tube test jig for
service, ensure that the jig is capable of handling
25.5 kV
without causing X-Radiation.
Note:
It is important to use an accurate periodically calibrated high voltage meter.
1. Set the brightness to minimum.
2. Use the remote to get into Service Mode.
3. Measure the EHT. The meter reading should indicate
24.0 ± 1.5 kV
. If the meter indication is out of tolerance, immediate
service and correction are required to prevent the possibility of premature component failure.
4. To prevent the possibility of X-Radiation, it is essential to use the specified picture tube, if service replacement becomes
necessary.
