Two weeks back I purchase a nec mt840 projector with the same problem. I brought it home, open it, and clean it very gently. Now I have a perfect working projector. you may just want to clean the inside. Another thing, check to see if the fan is working from the front end, you may just need cleaning.

Hi kmarie01

This is most probably a faulty Ballast ( lamp's powersupply ) that will have to be replaced before the Projector will come on at all.

Does a lamp error message (6 blinking red status lights) mean the lamp needs to be replaced? or could something else be wrong.


According to NEC technical support, if the status light flashes red six times, this could indicate a defective lamp. If a new lamp is installed and the project still won't turn on, the projector will need service.

I turn it on, the status light flashes... then it turns itself off, except the power button is still showing power and the status light is blinking red


Your bulb is not lighting.
Either the bulb has failed or it has a bad contact.
Remove the bulb to check condition and then reinsert and try again.
If it still does not light you will have to buy a new bulb.

Turn on the projector the power light flashes green with status as green then it goes to a flashing orange light


there should be a status for the lamp light; check to see if this one turns red. If it does count the consecutive blinks if it is 6 then replace the lamp

Power light flashin orange, status light flashing red on WT610 NEC


if the status light is flashing .5 seconds on and 2.5 seconds off - you need to replace the lamp cover correctly.
if the status light is flashing .5 seconds on and .5 seconds off in 2 - 6 cycles the error is: 2 cycles - the projector is overheated. Move the projector to a cooler location, or/and remove dust in the light path. 3 cycles - the power unit is not working correctly. 4 cycles - the fans are not working correctly 5 cycles - lamp fails to light. Wait a full minute and then turn on again.

Depending upon the way in which the lamp finally smoked, it is not unusual for the feeder fuse to blow. Replace the fuse and try the projector. As long as you haev a new lamp, it should work OK.
