Ignore the above solution. Your red polarizer or color filter is damaged. It is costly to repair this. But you will find this piece near the LCD optics. It pulls out from a tab.

The problem you have lies either in the CRT or the CRT card. If you are familiar with the term Video B+, check this voltage at the collectors of each of the output transistors on the CRT card. You should read about 175 volts or so at each collector. You will probably find that the voltage on the collector for the GREEN output transistor is low. If so, pull the CRT card off the CRT (with the set off to prevent any arcing) and double check that collector voltage again. If it is back to normal, then you can suspect that there is a short of some kind with the GREEN gun in the CRT.

Red color seperating

If you mean the red light is displaying offset from the blue and green then the red LCD panel inside the projector needs to be physically adjusted. If you take the projector apart you'll notice that the light source is split into red, green and blue light by passing through an optical splitter. Each color then passes through it's own LCD panel. Next, each color is joined back together by another light splitter to be projected to your screen. The red LCD panel is misaligned.

Can't red and green colors

This usually means the red or green or both primary color module is bad. Monitors come with 3 primary color module controllers and they use them in various combinations to make the other colors. The primary colors are blue, green, and red.

Red colour does not appear on screen.

It sounds like you have a bad VGA cable. Check for a bent or broken pin in the cable. These often show up as a loss of one particular color: red, green, or blue.

Listen, for what it is going to cost you to fix the unit, you are better off replacing it and having a new warranty to boot. Simply not cost effective to repair given the cost of a new monitor these days.

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.
