1980 Sears (Sanyo) 25" Console TV CRT Problem

I caught it when it snapped. There was a bright flash seen through the neck of the tube.

But again, this only occurs when I have HV applied.

But when it does it, it is identical to the symptoms Ischmidt mentioned. And it does it at random.

Otherwise, it is working perfectly.

Check the CRT socket around the Focus pin area, make sure it's not Carbon Tracked or damaged in any way.
If all is OK I'd probably just let it run and see if it clears up.

CRT socket is indeed clean.

Good news is the TV has been on for 4 hours now. The loud snapping actually quit completely about 2 hours ago. Frequency of it happening slowed down to about once every 10 minutes all the way down to nothing at this point.

I am going to let it run all night now since everything else is in check. Hopefully that will break it in so it quits doing that crap.
