The problem is the screen picture has reduced to a blue horizontal line in the middle of the screen that widens to about 2 inches on each side. Does anyone have amy ideas? I took the screen off to do a little looking and there are 3 projectors??? When turned on the red one on the left is off, the green one in the middle is off, and the blue one on the right does light up. ANY HELP would be appriciated. Thanks, John.
