What kind of projection tv are we talking about a lamp based unit? or a CRT based one? If it is a lamp based one then you could have a dirty light engine which is expensive to replace. If it is a CRT based one you could have bad convergence IC or one of you tubes is in overdrive and the screen voltage needs to be adjusted.

Red, Green convergence lines are wavy


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

Yes you have bad green and red crt but with an adjustment you can still use it. remove the front panel and you'll see the focus pack (it;s a black piece with 6 rotating knobs on it. Adjust clock otherwise the red and green screen (the bottom line knobs) till the lines has gone. The better way to check it is to adujt in video input with no signal, just black screen.
