HAd the same problem with mine, but was under warrenty, they took it to the shop and had to replace the Engine if you need the specific engine name I can look it up, now the bad news if I would have had to pay it would be over a grand for the part alone.

If the red light scrolls through, you need to replace the bulb. I replaced the my own bulb, and when I tried to turn on the tv the light kept scrolling. What was wrong? I DIDNT FULLY REASSEMBLE THE TV AFTER REPLACING THE BULB.
Make sure that all the screws are put back in and it will probably work if you have replaced the bulb.

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.
