What's the model number? Describe the distortion in some detail. Is it intermittent? Does it seem to affect anything else, like audio, when it's present?

Wavy colored line at upper right corner of set seems like something is pushing from top left and distorting picture from that direction.


Projection TV sets have two very common problems listed below.

Problem #1) 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

Picture shadow on rear projection Sony big screen TV


You have 2 distinct problems that should be addressed separately. Please repost the Samsung problem. I will address the Sony problem here.

If the "shadow" makes the picture seem somewhat of a 3D one, the problem is with the convergence circuit. This could be as simple as bad connections on the pins of the convergence ICs or defective ICs. If you can solder and would like to attempt the repair, update this and I'll provide more details and instructions.

Green semi-circle of lines on Samsung 55" HDTV (projection)


I believe i have the same problem myself. When my TV is on any of the Component Inputs without my DVD player turned on i usually get the normal green screen. But now that is a dip in the green at the top of the screen from the top left to almost the top right and black pushing down on the dip. Almost like a green curtain was sagging at the top and you can see the black behind it. It does this on every input and distorts every picture you see. The distorted picture has all the green slightly off from where the rest of the picture is and where the dip at the top of the screen is there is somtimes purple instead of black.

I know the basics of how the picture gets onto the screen and its my guess that the Green "gun" for lack of a better term and somhow come loose, or been missaligned to a great extent. I would love to find an answer to this problem, and anyones best guess as to how much a repair man will charge, just so i know the ballpark.
