Question about NEC MultiSync MT1050 Multimedia Projector

1 Answer

It's on, then it's off

My MT1050 turns on, displays picture, then about 2 minutes it shuts off. Status light blinks red for approx. 6 seconds and power light is steady orange. The manual only offers a 4 second and 8 second solution. Can someone tell me what might be wrong? Thanks

    The fan is running, the vents are not obstructed, and the filters are all clean. Once it goes throught the shut down and the fan turns off, it will turn right back on again. Any other thoughts?

    Do you know if this is repairable? Also, I have searched hi and low for a repair manual for this unit and have had no luck. Thank you again.

    Does someone know where the thermal cutout is located in this unit? Should it have gone bad in only 748hrs of use?

  • dna11207 Feb 16, 2008

    I bypassed the thermal cutout and it is still doing the same thing. Does anyone have any other ideas? Thank you again.

    We have a 'new' symptom the projector will stay on and running with no problems if it is sitting on it's back.

  • dna11207 Feb 17, 2008

    Well, I am going to assume that you are right that there was or is something loose that the pressure of having it on its back or upside down (which we hadn't tried till late last night) is reconnecting or what have you.... needless to say it is working just fine now thankfully, it was becoming a little aggravating to say the least.... thank you so much for your input we do appreciate it, now if we could just get a remote for it that don't cost $200 we would be good to go.

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

    Might just be that the thermal cutout is going bad inside the unit. Shutting off at to low a temperature.

    Sounds like the most likely cause. They do change properities as they get older.

    That last line you put there has me totally baffled.
    I honestly have been thinking about it all day and running fine
    sitting on its back.
    Other then disconnecting and reconnecting plugs and connectors, and possibly turning it on it's back is reconnecting a broken or cold solder connection, I honestly don't know.
    Actually, when I got that message on my blackberry I had to laugh.
    A bad connection, where laying it on its back puts enough pressure on is the only thing that makes any sense now.
    You sure are persistent I have to admit.
    Wish I could give you a better answer.

Status light is blinking red, power button orange nec vt700

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.

Sounds like you lamp ballast has gone bad. I good way to verify this is, when you press power on the projector look inside the lens. If you see a small amount of light, then the ballast is good, and the lamp is bad. If there is no light then chances are the ballast is bad.

NEC NP1000 powers up, strikes, then shuts down

the expected lamp life is an average .. its not unusual to see early failures ... check the lamp connections to make sure they are secure ... check ventilation to make sure its not blocked by dust .. if there is a fan, make sure its working ..

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! :]
