The light filter on the blue lcd panel is fried due to excessive dust and heat. clean out the projector with canned air. unfortunately, you cannot buy individual parts of the optical engine- you'll have to replace the whole thing. or live with it.

My NEC mt1075 projector is projecting a shade of blue all over. The entire screen is showing the correct image, but also with a shade of blue. I think something is wrong with the internal wiring. Is this a...


If you're using component video (red/green/blue rca cables) one of the colors may be disconnected, or the wires may be swapped into the wrong color input. If you are using a 15 pin VGA connector, one of the pins may not be getting good contact at the source or at the projector. Or if the VGA cable is split into 5-wire to make a long cable run, one of the five wires may be disconnected. Any of these problems will cause a global color shift while not affecting the color of the projector's on screen menus.

Changing the lamp


There is a small cover plate, about 3"X6", that 'just' snaps off. You might have to use a small screw driver to pry it open. The bulb can then be pulled out. Align the new bulb and press it down into the socket. Be careful not to touch the bulb with your hands; use gloves or a lint free cloth.

VT45 Projector: Blue pixels throughout screen


If the problem is what I describe as a blue haze over the entire image projected, I was told this is a defect in the cable - we have a Dell Video Projector 2300 - and it takes only a dell VGA cable.

So, the problem is in the cable - solution is replace cable.
