Nec projector vt590 doesn't project RED

18 month old nec vt590 projector that's been used less than 100 hours doesn't project RED, just BLUE and GREEN. On occasion the RED will flash in for a moment, then back to the B & G. Any ideas what's wrong?

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.

My nec projecter lamp status is just red on and not working any idea


Usually the unit will go into permanant standby if the lamp life exceedes its safe limit. I had the MT830/1030. To reset it I had to press the off button down for upto 20seconds which resets the lamplife. If not the off button it was the on button.

Good luck

I need to reset the lamp timer after replacing the lamp. Red status light.


Some of the NEC units have a standby status when the lamplife has exceeded its safe limit, the unit I had needed the off button pressing for up to 20 seconds to reset the lamplife and allow the unit to be switched back on. There should be info for this in your manual. (It could have been the on button, can't remember now)

Good luck

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.

I have a NEC mt1055 and the unit just had new bulb put in here and it has the power and standby light come on and the fan doesn't turn on here and the standby light is yellow and status is red


The NEC’s work on a reducing time basis, they count the hours that they have been operational and refer to this as the life of the bulb – 1600 hours. When the 1600 hours has been reached the projector shuts itself down into standby mode never to be restarted even after changing the bulb / filters. This is because the unit needs to be reset, which needs to be done as follows (not included in any of the bulb replacement instructions):-
  • Plug Projector in so it is in standby mode – Orange light lit, Red status light lit (not flashing)
  • Using the remote control, hold down the power off button for 30-45 seconds
  • This will reset the status button, removing the red light
  • Power up the projector and select Menu
  • Select Projector Options
  • Select Set-up – a number of tabs will appear called pages
  • Arrow across the pages (MT850 is Page 5) until an option called “RESET LAMP HOURS” is shown
  • Move onto this option and press enter on the projector itself, confirm that you want to reset the counter
  • Projector is now back to life

This works for all NEC projectors, the page number may be different though where the “RESET LAMP HOURS” option resides.

I turn my mt850 on & the picture is blue


You most likely have a defective blue LCD panel which is a common problem for a projectors this old.
This is an exspensive repair if parts are still available, probably not worth fixin.

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.

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.
