Red Lines through picture when screen is dark, back ground has a red tint. On my 48 "Sony Rear Projection" TV
You can try adjusting the Red color output. (Very touchy adjustment)
you take off the front cover/speaker cover, there should be a access panel. Behind
that, there should be a small square black box with 6 screws on it.
This is the focus block. (At least this is where most of them are
It sounds more like you may need less red in the mix. There is a screw for each color. R, G, and B. Do not
mess with the focus screws, just the ones labeled 'SCREEN.'
Go to an unused input where the screen should be dark. Barely turn the red down in a dark room so that the red spot is at the same level as the Blue and Green.
Use an insulated screwdriver and DO NOT TOUCH the focus block and ESPECIALLY NOT the back of it.
Very HIGH VOLTAGE. I found that out the hard way.
Do not turn any of these up too high or damage may occur and the TV may detect a short and shut off.
have found that if the three colors are adjusted in a dark room to
where the 3 color spots (R/G/B) are just barely visible on the screen
at equal levels, there is a pretty good color balance.
I hope this helps! Just be careful.
