Question about Televison & Video
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.
