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.

Re: nec gt2000

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 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.

My NEC MT850 projects with a pink picture you can still see image but it is a very bright pink.

A pink image normally means a loss of green signal.If you are using Computer input you should try replacing your input cable to see if this is the problem. If it is pink with video also then the projector most likley has a internal problem.

Nec projector vt590 doesn't project RED

Red, Green, and Blue signals come from different wires in the VGA cable.  This sometimes happens if a cable simply is not connected fully.  But it will also happen if the cable is damaged.  The damage might be visible in the form of a bent, broken, or missing pin.  Or it might be internal to the cable.
Try another cable.
If that's not it, then the connector on either your computer or on the projector itself might be damaged.
Also try another computer.
Components inside the projector could also fail.  But I'd bet on a cable problem any day.

NEC Lt240 prblem

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.
