Question about Sony KP-53XBR200 53" Rear Projection Television
The picture is very fuzzy with a snow like effect. I have tried all the inputs and have the same problem. When I go to picture in picture the small square picture is perfectly clear.
I'm working on the same problem with a 53XBR200. I think the failure is in the BR board. PIP video is routed through the BM board and full-screen video gets routed and upscaled through the BR board. Whenever video is displayed in any of the PIP modes, the video looks fine. When you go back to full-screen, static appears with every input and ant. I've tried routing video by bypassing the BR board, but this doesn't fix the video. I think the video processor which receives video from either the BM or BR board is expecting 480p. Since the BR board is no longer available from Sony, the only way of making the set useful is to find a way to bypass the BR board, or repair the BR board itself. Has anyone else encountered and/or solve this problem?

When you say you have tried all the inputs you are not clear if you mean tuner, vcr, dvd, aux, etc. If you are talking about only the cable input it sounds like you have a bad tuner. To obtain picture in picture there are 2 tuners in your set. This would explain why the small picture is ok while the main picture is bad. You should be able to swap the signals (see your ops manual). Try this. If the snow moves the one tuner is bad. If you have put other signals in (besides cable)such as dvd then the problem is in the matrix circuitry where the two signals merge. Either problem should be easy for a good tech to solve and not cost a whole lot.
