Question about NEC MultiSync MT840 Multimedia Projector

1 Answer

The projector won't turn on... the status light blinks slowly (on and off in an 8 second cycle). The troubleshooting section says this means the cooling fan has stopped and that I should contact an NEC dealer. The thing is, I can feel the fan still working. I've cleaned the filters... is there something else I can do to get this thing working without having to pay large quantities of cash to ship it in and get it fixed? Seems like it should be a simple problem.

Status light is blinking red, power button orange nec vt700


Hello
Look at the number of blinks of the status light.
[1] If it blinks at one cycle (0.5seconds On and 2.5seconds OFF) : Lamp cover error or lamp housing error. Replace the lamp cover or lamp housing correctly.
[2] If it blinks 2 cycles (0.5 seconds ON and 0.5 seconds OFF): Temperature error. The projector is overheated. Move the projector to a cooler position.
[3] if it blinks at 4 cycles (0.5 seconds ON and 0.5 seconds OFF): Fan error. Fans sill not work correctly.
[4] If it bliks at 6 cycles (0.5 seconds ON and 0.5 seconds OFF): Lamp fails to light. Wait a full minute and then turn on again.
[5] If it blinks continous (Red): Lamp has reached the end of its life. Lamp replacement messege will be displayed. Replace Lamp with same type and number. After replacement reset lamp hour. OK.

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.

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.

Blinking status light


Replacing the lamp with an old one was helpful for me. Good news: the projector itself not faulty. Bad news: I have two projectors with the same issue at the same time (the lamps were replaced also at the same time) after only 400 hours of running.

It's on, then it's off


Is the fan running properly or are any vents blocked?
Sounds like it is overheating.

Status light blinking red


If it is a lamp error try this:
When the lamp exceeds 2100 hoursof service, the projector cannot turn on and the manu is not displayed. Do the following:
For VT670/VT470 Press the help button on the remote control for a minimum of ten seconds.

For VT570/VT47 Press and hold the power and the exit buttons on the remote control simultaneously for a minimum of ten seconds. When the lamp time clock is reset to zero, the lamp indicator goes out. Hope this helps! :]
