High Voltage limiter circuit operation check.
1. Turn off TV and connect jig as shown in Figure 2. Adjust
jig fully counter-clockwise for minimum resistance.
2. Set the AC input to 120V AC and turn on TV.
3. Confirm test pattern on CRT is a usable picture, then
slowly adjust jig until the picture disappears and TV shuts
down.
4. When the limiter circuit is operating properly, High
Voltage will be less than 31.5 kV at 1.7mA when TV shuts
down.
5. Turn off set immediately after checking circuit operation.
6. Unplug set for one minute to reset shutdown circuit.
Remove jig and voltmeter.
