2 to 3 weeks ago my 4 year old rear proj panasonic TV had blue ghosts and then horitontel lines became waivy. After reading this website I diagnosed the problem as being the convergence. Now after this weekend the picture will not come on and I only hear the sound. Is it the convergence and the bulb? Or did we kill our TV because we were not prompt on fixing the convergence and contiued using it even though the picture was distorted?

Re: Panasonic 47wx53 covergence issues
Is the power indicator flashing three times? If so the Ics have shorted shutting the set down. You will need two STK392-110 convergence ICs. You can get replacement ICs at the following link with free installation instructions. http://servicemanuals.vstore.ca/

yes and also possibly the low ohm resistors. You can get the PT53WX53 convergence kit which fits your model from www.tvrepairworld.com which has the 2 ICs and associated resistors plus the CD with repair instructions.
Blue background lines with colors otherwise OK may be a loose or dirty blur drive potentiometer on small circuit board behind front grille and beneath front imerboard cover. These are hot-glued in place from factory but may be the cause f the problem. They're VERY sensitive.
If you have bowed blue lines instead of properly aligned colors, you probably have a blown convergence amplifier IC. These boards are no longer available so yours will have to be repaired. Some shops repair them but many send them out for 6-10 weeks. Fairly expensive too considering the amplifier chips are about $35 each (x2).
rear projection TV is light emitted and therefore can be fixed by a lamp replacement. I know the replacement's can in some cases be more expensive than a new model. Search the web for lamp replacement based on your TV model to get an idea.
I have a Panasonic PT-47WX53 rear projection TV and the picture was pretty dark for the last year but for game it was OK but know the blue is out of sequence, do I need to change the lamps?
And where to find them?
Sounds like you have a blue foldover in the convergence. Since tv has been worked on it could be bad ic, maybe not original, generic. I would say if you can open set and look in, look for the blue it should be marked. look for a loose connection. If you can have someone to gently tap around that blue amp and see if it moves are go away, it might be a simple loose connection and needs soldering. If not then my have to change ic again. Becareful cause set would need to be on to really check. Hope this helps.
