The picture projects the image with concave lines on the edges. I'll explain further: somehow the picture is distorted in a way that bends the four edges of the picture in a curved-concave manner so that...

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

Red and blue colors go across the screen. picture looks concave.

Greetings joanne7,

The issue you are having could be caused by your television needing the convergence adjusted. During production your televison has the three picture tubes that are converged to form a single image on the screen. Over time these can come out of adjustment.
If you go to this link http://download.jazel.net/misc/filecache/b8/b89bca4c8b740315d378e8ed030461c5_1227-517SeriesOwnersGuide.pdf and check pages 57 and 58, it gives you a very detailed guide on adjusting your convergence. I am aware this model number is slightly different than yours, but I own a 47" Mitsubishi and this is the exact procedure we use to do our convergence so I am confident it is fairly universal.

I hope this helps!

Mitsubishi projection tv

I have a similar problem. I have tried to fix the convergence via the remote and that has not helped. My three colors are separated and the edge of the picture is bent in toward the center. I am going to try a hard reset but i suspect the convergence IC are fried. Since the set is not HD, I will probably replace it if the hard reset does not work.
