Out of curiosity, does anyone have a sense of what usually causes flybacks to fail?
I suppose overheating is never a good thing and it can readily lead to failure. But what's the typical scenario? A problem in some other circuit makes the flyback overheat and then croak? Or is there some internal factor (similar to old capacitors being imperfectly sealed against air/moisture) that means many of them are doomed to fail eventually, even if the rest of the TV works perfectly?
Just wondering . . . .
