I have recently gotten a red arching tint in the bottom picutre of my rear projection tv. It come upward about 1/3 of the way on the screen from the bottom up. I have adjusted my red, line adjustment but that doesn't do anything and it is correct. When this first started you could tunr it off then back on and it would go away but it stays there now no matter how many times you turn it on and off. Please Help !!!!

How do you align the red lamp?

Brett, February 2008

Hey Brett,

The only thing I can think of is that your TV uses three seperate "projectors" for the three colors, RGB (red, green, blue) and it sounds like your red projector is not perfectly alligned with your green and blue projectors. This usually happens over time due to heat. The only other issue might be that the lamp in your red projector is going out and might need replaced. That would cause the red arch on your picture.

hope that helps,
