2. X-RADIATION
WARNING :
1. The potential source of X-Radiation in TV sets is the High Voltage
section and the picture tube.
2. When using a picture tube test fixture for service, ensure that the
fixture is capable of handling 34.5 kV without causing X-Radiation.
NOTE:
It is important to use an accurate periodically calibrated high
voltage meter.
1. Reduce the brightness to minimum.
2. Set the SERVICE switch to SERVICE .
3. Measure the High Voltage. The meter reading should indicate 28.5
kV±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.
4. To prevent an X-Radiation possibly, it is essential to use the
specified picture tube.
2.1. HORIZONTAL OSCILLATOR DISABLE CIRCUIT TEST
SERVICE WARNING :
The test must be made as a final check before set is returned to the customer.
1. With the rear cover removed, supply about a 120 V AC power
source to the set, turn on the set.
2. Set the customer controls to normal operating positions.
3. Short between TP891 and TP892 on the Main circuit board with a
jumper wire. Confirm that the picture goes out of horizontal sync.
