If your TV looks 3D, warped, or distorted it likely has a convergenge problem.

I've had this problem with my projection TV recently. I would say your lens/lamp is to blame. It might be time to change it, depends on the last time it was changed, most of the time, the TV will tell you that it needs to be changed, but not always. I think your best bet is the TV lamp.
Check your color wheel. There is a DIY guide for replacing the color wheel. Mine did the same thing yours is and my color wheel was all busted up. Unfortunately after replacing the color wheel my set continues to do the same thing, but this could mean I need to replace the ballast as well.
You need to put in the values for x,y, of red,blue,green & white.
when you get the color wheel, sticker(printed values) was in the same box.
If you have, let me know and I''ll let you know how to put in.
Sounds like you've lost your red video signal (chroma) somewhere along the line. This tv has a 3 board video path. Analog main pcb --->Digital main pcb --->DMD pcb. The analog has all your inputs on it, except DVI and RGB which go straight into the digital board. The digital scales (upconverts) the signal to HD (1080 or native) and sends it to the DMD or light engine. See which inputs are distorted. If only DVI is clean then you problem is the analog board. If you menu and everything is distorted then suspect the DMD board. If you run component or DVI through the resolutions (480i, 480p, 720p, 1080i) you can get an idea between the digital board and dmd. The menu is generated on the digital board. Somewhere red is getting lost.
