I have red coming though when there shouldn't be anyone on the screen.
For instance, If I am at a no-input screen I can see some red on the
screen.

There are typically separate red/green/blue level and drive
adjustments in a TV set; get a good grayscale test pattern
(I assume you can hook up a DVD and load a test disk)
and adjust levels until the black band is without tint,
then adjust the level controls until the white band is also
neutral (white) in color.

These adjustments are on/near the video amplifier board,
and always well labeled (like, with red/green/blue colored
knobs). The SCREEN control also may be beneficial,
it's likely to drift with time. I'm not sure if you have a one-CRT
or three-CRT or LCD or DLP type projector, though...

Projection TVs also will benefit from dusting of the optics.
