This is my far my favorite set. Despite it's issues I still use it the most.

Ever since I got it, I've noticed two things:

The 12V power supply board gets very hot.

Sometimes I will hear a snap inside the set, and it will flinch then go back to normal. It was extremely dirty inside when I got it. I have done a lot to clean it up, and I made sure to clean the flyback off.

I've used the set for many hours apart, and done some probing around inside. I get no arcing from the flyback anywhere, and it has no signs of voltage leaking. The only thing I can think that would make a snapping sound like that is an arc from the flyback it self. It's not done it in awhile since I cleaned it up, and cleaned the wires going to the tube from it.

I still suspect I need a flyback for it. Is this something that will be impossible to find? Or have other members saved parts from these sets before?

I might have one, but it will take quite some digging to find it.

Usually if the set still has HV it is not a flyback problem. Have you thoroughly cleaned the side of the CRT by the HV connection? If not do it with rubbing alcohol or windex.

Yes. I have cleaned it with contact cleaner on Q-Tips, all the wires, the transformer it self and the top of the CRT and the anode cap as well. It was really caked on heavily.

I also cleaned the wire going from the flyback to the board on the back of the tube it self. They were all caked with dirt.

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.
