Its the dlp/dmd chip going and soon will look like the star screen saver on windows 98. it will need replacing. they start with one or two dead pixels then it spreads. ref only->https://www.replaceyourlamp.co.uk/projector-lamps/nec/np-u250x/dmd-chip-1076-6439b/dlp-dmd-chip-1024x768-pixels-model-b.html

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.

You can't. That symptom is caused by failure of one of the LCD panels. Not worth repairing unfortunately.

No. Mostly you need to change the engine. Please take it to service centre

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.

Using the on screen menu, check the hue or wall color settings. [Hue]
Varies the color level from +/- green to +/-blue. The red level is used as reference. This adjustment is only valid for
Video, Component and TV standard inputs (not valid for RGB and DVI digital).


Using the Wall Color Correction [Wall Color]
This function allows for quick adaptive color correction in applications where the screen material is not white.
The following nine options are available.
• OFF • Blackboard
• Blackboard (Gray) • Light yellow
• Light green • Light blue
• Sky blue • Light rose
• Pink

Hi 80camaro

You could check in the Service Menu if your RGB is the same percentage and at the same run rate.

The run rate is normally 45-60 and the percentage on 50.

I would however recommend that you take it to a NEC agent to get it serviced.

If this doesn't fix it , then you will be looking at a new Mainboard.

Thanks for using Fixya and good luck.
