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

Well, you did the right first step. However, when the convergence outputs toast up they sometimes cause other problems. First would be the fuses that supply them voltage. These are pico fuses back in the power supply. Second would be open supply resistors that have opened up because of the excessive current draw caused by the whacked out convergence amps. When changing the outputs doesn't solve the problem it takes the repair out of the realm of the do-it-yourselfer. My recommendation is to let a professional take over.

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.
