Question about Sony KP-51HW40 51" Rear Projection Television

1 Answer

Sony kp53hs30 screen is curved at top/bottom when in widescreen

Greetings. Shortly after I bought my kp53hs30 tv, I noticed that when viewing certain direct tv channels, the picture quality, (particularly red, or fleshtones) was pixillated, or would show up in small squares at times, and would look really grainey. I called the service center where I bought the tv, and they sent a tech out. Neither myself nor the tech knew at first that the problem had to do with the compression methods that Direct TV was using at the time. We thought there was something wrong with the tv. The tech made several adjustments. He was able to locate a bulletin describing the compression problem, and how to make adjustments to the tv to compensate for the problem. He fixed that problem, however, in the process, the picture is now curved in slightly at the top and bottom of the screen. I didn't notice this immediately, because at the time, I had always used full screen/480i. Now that I own several wide screen dvd's, and more and more channels now broadcast in widescreen, the curved picture is quite noticeable. It's not horrible, but I would like to correct the problem. Somewhere in the service menu there should be a setting that will adjust the top and bottom curve. What option would it be, and how do I access it? Other than this minor problem, it's been a great tv. THANKS!!!!!

SONY PROJECTION TV MODEL # KP-51WS510.


If the entire screen is curved, and it is not taking the whole screen, then you have a vertical deflection problem.

If the colors are double and do not match, with lines of different colors around pictures , then you have a convergence problem, often caused by a faulty convergence board.

The curving effect can be a side effect of bad convergence, or you may have both problems at once.

Unless you are a TV repairer yourself, better calling technical support. Usually you can ring the number listed on the owner manual.

Lines on top and bottom on projection TV


What sort of lines? - do you mean like it is in widescreen mode with a black band top and bottom? Do you mean you have clear straight lines, or streaks or scratch-like marks? Is it the same for all input sources (cable, DVD/VCR, satellite, PC, camcorder etc.? Could you post back a photo of the lines? Waiting your info:)
