Sony Trinitron KV5100 problems.

It may be an internal arc in the CRT also.
If its the HV it will do it more on humid days.
Best to open it up, run it in a dark room & watch for it.

BTW most Sonys use a coax HV lead. When removing
the lead there is a little spring that connects the center.
If you dont remove it carefully it can get bent up or lost.

I noticed that. I was able to get it out, and then reinsert it correctly when I removed the wire.

It's not done the arcing in a couple days. I am not holding my breath, so I don't use the set for long hours.

I've tried letting it run for hours with it open in a dark room; Nothing.

I even tried probing around all the HV parts while it was on to see if I could cause the arcing to happen, and again, nothing.

All I can say is the the set was internally very dirty, and whatever the grime was it built up inside was very thick.
