Perform the following when the HV connector (anode connector)
is removed or inserted for CPT replacement, etc.
- Roll out silicon cover from FBT’s contact area slowly.
- While turning the connector about 90 degrees following the arrow (0 position). Push the connector slightly toward the case.
Remove the connector slowly by pulling it away from
the case.
- Refer to direction for insertion as shown in Fig above (L position). Insert connector until “CLICK” sound is heard.
- Make sure the connector is pressed right in, so that it has a good contact with the spring.
- Confirm the contact by pulling the connector slightly. (Don’t pull hard because it may damage the connector).
- Cover the high voltage output by carefully pushing silicon boot onto it. (Don’t turn the connector).
High Voltage limiter circuit check
- Turn off TV and connect jig as shown in Figure. Adjust jig fully counter clockwise for minimum resistance.
- Set the AC input to 120V AC and turn on TV.
- Confirm test pattern on CRT is a usable picture, then slowly adjust jig until the picture disappears and TV shuts down.
- When the limiter circuit is operating properly, Voltage will be less than 36.5kV at 0.6mA when TV shuts down.
- Turn off set immediately after checking circuit operations.
- Unplug set for one minute to reset shut-down circuit. Remove jig and voltmeter.
Remove RH 80 and connect 50K Ohm jig as shown.
