Question about Panasonic PT-53X54 53" Rear Projection HDTV-Ready Television
The picture on the tv is now just 3 skinny lines going up down on the screen that are red blue and green side by side, can you please help me?
The shutdown you're experiencing is most likely the x-ray protection circuit sensing an abnormal voltage problem in one or more areas. And it could be multiple problems causing what you've described. First I'd start by checking for cold solder joints, specifically on D21, D22, and D23 in the convergence circuit. You will also need to do a trace test on the resistors feeding the convergence amps and the amps themselves may need to be replaced. If this sounds like something that's a bit beyond you're capabilities take it in to a reputable shop. What you're describing is a handful even for the most qualified. At the very least you'll need a good DMM, ESR meter and scope.
