I have a Phillips Magnavox projection TV model 9P5511 C102...I heard a loud squill when I turned on the tv for a while like if it was a transistor or something...but now when I turn the tv on the picture will shrink half size and get real light but if the show on the tv is like a dark background the TV will be a normal size and is plain to see....I got it apart now and do not see any burnt places lol and I have read the mini fixes on here about an opto - isolator being bad...I know how to soldier and familiar with capacitors so I just need guidance as to where this thing is?
