Warning :
1. The potential sources of X-Radiation in TV sets are the High Voltage section and the picture tube.
2. When using a picture tube test rig for service, ensure that the rig is capable of handling 31.7kV without causing X-Radiation.
Note: It is important to use an accurate periodically calibrated high voltage meter.
1. Set brightness to minimum.
2. Measure the High Voltage. The meter reading should indicate 31.0 +0.7, -1.5 kV. If the meter indication is out of tolerance,
immediate service and correction is required to prevent the possibility of premature component failure.
3. To prevent possibility of X-Radiation, it is essential to use the specified picture tube.
