Question about NEC MT1075 Multimedia Projector

1 Answer

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 common problem?

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.

Blue haze in top right of screen from NEC mt1075 projector


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.

Bright yellow


I can't imagine a setting that would cause this - It sound more like some sort of fault with the projector's blue LCD panel. (The image is created from a mix of red, green and blue light. If you loose the blue, everything will look yellow.)

Is it capable of showing any shades of blue?

Using any graphics or photo-editing software, create a solid blue image (R=0, G=0, B=255 in your colour settings) and if possible, display this full-screen. Is there any output from the projector at all when you do?

If not, it sounds like it need a professional repair.

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.
