I have a RCA ,model number F32649

I noticed the screen was flashing with a arching sound coming from it. I pulled the back cover off and plugged it in.

The screen and focus assembly produces a blue spark across the assembly at the same time the screen flashes. Whats going on???

How can this be fixed?
Thanks

Just did some research and the part making sparks is the flyback transformer.

Just as an update. I sanded the flyback transformer to remove the carbon and cleaned with alchohol. I then used clear silcone and patched the pin sized hole . I applied it thick and over a large area. The tv now works .

My question is how long will a fix like this last? I have located a flyback transformer and will most likely order this as a back up. Anyone done this before and know how long this will last?
Thanks

As i understand it silicon won't burn until around 1000 degrees and is used on circuit boards all the time.
