Jim,
I totally agree with you, their just prolonging the problem and not taking
care of the problem! By the way Iv'e also had the horiz. driver
transformer(#215541) and cap C4306(#188594) cause overheating of the HOT.
I've also got written down in my tips that C4709(47m-50v) can also cause
overheating. I'm going to add your three suggestions to my list of causes!
