Question about Samsung PCN5425R 54" Rear Projection Television
The picture on my tv appears to be pushed in, curved in the middle, and also has a double image. What could that be?

I had noticed your question before posting mine, since it appears no one had given you a solution thought i would share the solution given to me. Two different techs told me the same thing it would need a new convergence board. I ordered my board today hopefully have fixed soon as it arrives. I noticed your question has been hear awhile but thought maybe if you still needed some help I would share. It is going to save me $300 doing it myself, but if you are going to try make sure to talk to one of the techs first on live chat. Goodluck

This sounds like your convergence correction amplifiers have malfunctioned. These Integrated Circuits often burn out after a few years (STK392-110) they can be replaced with a higher version (STK392-150) However it is important to have the biasing circuitry checked to make sure nothing has burnt out as a result of the ICs malfunctioning. If you have a background in electronics you can repair this problem with very little effort, however if you do not have a background in electronics, I would suggest that you have your TV serviced by a qualified TV technician.
I hope this helps,
Thank you,
