1,Check the fans ,whether each fan is running,when you turn on the projector
2,if the fans run, then ,check the lamp or lamp ballast
turn on the projector ,at the same time ,if you can hear a continuous beep beep sound (the ballast igniting the lamp)
means the lamp may be fault,and other parts is working well

We cleaned the filter on the projector and it has never happened since. Assume that it was overheating due to lack of airflow.

SOURCE: my NEC MT850 projects with a pink picture you can

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.

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.

NEC MT1050 Lamp Error
Does the status light stay on red? If it does then the lamp timer has exspired and will not let the projector turn back on until it is reset, at which time you should replace the lamp. To reset the timer you need the remote control, with the unit plugged in in standby mode hold down the power off button for 30 to 45 seconds until the status light goes off.

NEC MT850
As there were no indicator lights lit I focused on the AC. The projectors work as they should in another location and as such I am fairly certain the problem is associated with the AC power in the particular room. I haven't isolated the exact condition as yet.

Thanks
