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!!!!!

Just about any tube TV is a 4:3 picture shape and most current TV is 16:9. so there is a compromise to get them to work together. Unless you are viewing retro TV shows, you should adjust your Digital converter so that you have a black band top and bottom (yes you are giving up screen). The alternate is to keep 16:9 and give up left and right sides of the program. Or properly recycle the TV and buy a LCD screen. Even used, smaller ones can be had for 20 bucks. I bought a 32" for 30.
In case I have this wrong and this is a new screen problem, make sure there are no magnets anywhere your TV. They distort. Have you tried back adjustment screws? Use a mirror or have a friend help. Look especially for pincushion adjustment.

The top and bottom bars are standard widescreen viewing. Your TV should have a zoom feature that you could use to zoom in past the standard 16:9 format. Look for a zoom button on your remote or in the tv setup settings.
Those sound like what is called "scan lines" and are the result of the way the picture is "drawn" on the face of the screen. Something in the set is allowing too much drive to the screen, as these are usually suppressed during normal operation...accordianman
This looks like Pincushion problem. nothing you can do. Only a Trained technecian can do this adjustment to reproduce a perfectly aligned image. It requires a pattern Generator and other tools. call the company tech.
it sounds like a convergence adjustment problem. If you hava book on the tv still read it, and it will tell you what to do, other wise, look for a convergence button on the front of your tv, and take the remote and push menu to bring up setup, and go convergence adjustment click it and hit the conv. button on the front of the screen. there should be to lines going vertical and horizontal, these are the limes you adjust with your remote, you have to adjust the red and blue, the tv should blink to let you know which color you are on. when you have them lined up right the line will be perfectly white. hope this helps
