Red bar across the top.

your tv needs a y-load board its like a grafix card as computers have due to overheating the board components are affected this is a manufacturing fault it tends to happen with samsung aswell

had tv that did the same thing after three years but they were green cost me 300 bucks to get it fixed and the guy said every 3 to 5 expect it

its in your LCD connector re-connect it properly.

the cost of the repair is fair. The color wheel is about 175.00 some other areas in the tv with the kind of problem you are relating can cost the board just above 200.00 until 350.00 then only the color wheel can practically cover the cost you are about to do. Plus labor. make sure they give you the 3 months warranty.

Replace the optical block assy

If you see a redish bar across the top, you have a bad light engine. You may also see a bluish bar across the bottom. Contact local service company for repair.

Projection sets have two very common problems.

The first common problem is convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

We have aKDF-E42A10 for a bout 2 yearsnow and we now have 13 horizonal lines across the screen, they look like small square dotted lines across the entire screen from top to bottom. It be gan acouple of months ago as 2 of these lines that seemed to move up the screen. I called technical support and he made it sound like he never heard of the problem. I am very upset with sony right now. Anybody know how to fix the problem?ricedog

I had the same horizontal, solid red bar along the top of the tv screen. I have an older analog Philips Magnavox TP2785C221. It just started all of a sudden. It was on every channel. However, the bar did not appear on the other input channels (e.g., AV1, AV2). So this meant that the red bar was only occurring on the antenna input. I unplugged my cable decoder box and restarted it. The red bar went away and that seemed to solve the problem for now.

I just had my HP-R4252 repaired on 12.05.09 with a similar problem. The picture is covered in horizonal, broken lines and the color is predominately red. They lines are grouped together in large bands across the screen.

The tech replaced the Y-Buffer boards (Up) and (Low) in about 20 minutes.
