Re: 1 inch lines on top and bottom of screen

Is the picture overall too small by 1 in. on top and bottom? Or is it cut off by the lines?

If it's too small, look for an adjustment labeled Vertical Height. This may only be accessible internally, it's normally a service adjustment, not a user adjustment.

Your problem is a vertical deflection issue, either an adjustment or the vertical circuit requires repair by a technician. In the latter case, electrolytic capacitors are a likely cause.

Do u know the dimensions of the rear projection/it quit working

These are the dimensions of the TV itself (including the bottom piece)
The height of the TV is 37.2 inches tall
the width is 49.6 inches wide
the depth is 17.4 inches deep.
the weight of the TV is 132.5 pounds (just thought you would want the weight as well if you are considering purchasing a stand)

RCA P52755BA 52 inch tv looks 3D

You have a problem with convergence and all you may need to do is replace a fuse. Look up convergence for your tv model and hopefully you will get an answer as to where the fuse is located and how to replace it. Very common for RCA tv's

Blue tint on bottom of screen

I have the same KDF60XS955 sony and have the same problem. I called sony customer support and was told there was a recall on the optical block for this tv. But the recall ended in Dec. of 2008. I was upset that they did not call or send out a notice to me. They should of had my information because I had a different issue that they sent someone out to fix a few years ago. They said it was an expensive fix, like over 1000 dollars. Instead of fixing it they offered me a deal on a smaller tv, a 52 inch sony. I could buy that one at a discount which is about 1100 dollars. I told them that I thought that was the worst deal I have ever heard of. Why would I spend about 4000 dollars for a tv 4 years ago only to be told that I could buy a smaller one today for 1100 dollars more. I said if I bought that 52 inch tv today, what would happen 4 years from today, am I going to be offered an even smaller one for more money again? I thought I was buying a top of the line tv back then, I only wished it would have lasted longer than this. Not happy!

RCA 52" projection Model no. D52W19 produced 9/04

make sure you do not have the automatic screen mode set to wide screen on tv menu .Also if you have cable box set to wide mode only then the tv will only display wide mode.
