You most likely have lost red lamp function. This can be caused by a number of issues. None are going to be an easy fix. You can isolate the problem quickly if you are a tech, by doing a red/green gun driver board swap. Pretty much the only thing you can try to do yourself, is take the front panel off the TV, then adjust the color bias knobs usually located somewhere behind the panel. One will control the red, one for blue, and one for green. Mark them before you play with them, so you can return them to the factory settings if needed.

TV picture is red.


Normal color picture is composed with 3 colors R-G-B (Red-Green-Blue). Picture turns Red means: Missing Green and Blue colors (many reasons: bad contacts, projector tubes dead, and other...). Try to give some "tabs" to diagnose ... I don't know what is the type of your Projection TV, how long you owned it, to have more idea.

Turns green and shuts off


I had an electrician come over. He pulled out the bulb that was dead (for me it was the color that was flashing before it would turn off) and now I have a blue and green TV with no red. He said that the only way to fix it is to replace the red lamp with a new one.

Color


Have you looked in back of set to see if the red and green crt's are lit? Also you can turn up the screen control for the red and green to see if there is a problem. If you find problem turn back down. Then problem will be somewhere else. Could be crt board or main.
