Question about NEC VT470 Multimedia Projector

Open Question

NEC lamp error

I see your answer from 2007 on this LCD... I've put in a new lamp; can't get it to light up; status beeps 3 times then flashes lamp error (6 flashes)...holding the help button for 10 seconds does nothing; tried turning it off/on, etc.

Is there any fix that you ever found for this? thanks.

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! :]

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.

SOURCE: LAMP not switching on NEC HT410

I had the exact same problem and solved it. After calling NEC tech and getting no help, my son and I decided to:

  • Remove, clean and reset lamp.
  • Completely clean (with compressed air) system.

And it worked. Here's what we did.

  • Removed lamp and cleaned with compressed air (in cans).
  • Used two cans of air to completely remove all internal dust. In our case long over due.
  • Reinstalled lamp and reset meter. (To reset: Turn on machine, wait 2 minutes or so, then hold down the "Help" button right next to the infrared sensor on the front of the machine).

Works fine now! Dont know if it was technical solution but solved it for us! Good Luck!

SOURCE: nec vt470 lamp does not come on. replace lamp,

If you replaced the lamp already, chances are the ballast is defective. When you power on the projector with the power button you should see a flicker of light in the lens, or an electrical sound. If you don't you ballast is bad.

That is a problem with the lamp. Replace it with a known good one.

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.

My NEC vt 595 was working fine last night and today i went to turn it on the status and power light started flashing red and orange and there is no picture


if Power is flashing orange - then it's cooling down

if Status is flashing red - then there are 4 flash combinations.
1 cycle (0.5sec On, 2.5sec Off) lamp cover or housing error
2 cycle (0.5sec On, 0.5sec Off) temperature error
4 cycle (0.5sec On, 0.5sec Off) fan(s) error
6 cycle (0.5sec On, 0.5sec Off) lamp error

Which is your condition?

I have replaced bulbs in 3 different types of NEC projectors: a silver, older model thta uses a VT60LP bulb, model VT595 and VT470. The lamp will still not work - the power and status light just continue...


I had the same issue, what I figured out was that I never removed the lamp door correctly, causing a small plastic piece to break off. To see if this is also your problem, inspect the back of the lamp door, top right corner, if it seems a rectangular plastic piece is missing, thats the problem. It presses in a small button nearby the lamp to let the projector know it's safe to power on.

Hi I am having trouble with an LT180 DLP I'm getting a series of error messages culminating in the power light steady orange and the status light flashing a series of 6 flashes red. Inside I found that...


both lights flashing green indicate the projector lost power while it was running (didn't get to go through shutdown procedure). if the status light blinks 6 times, the lamp is failing to strike (one time means the cover is open, 2 times is a temperature issue, and 4 times is the fan). if it comes on and shuts off a short time later (less than 15 seconds), the ballast is going bad and needs replacing. if it didn't come on at all, it'd be either the ballast or the colorwheel. if the lamp light was red, it would be the lamp that needs replacing. nec won't sell parts to anyone who is not an authorized nec service center, so you'd need to contact one to get the part (although they may not sell it to you). but good luck!

No Picture on my nec VT676 model


Hi there

I'm shocked that NEC can't answer this guys.

The NEC's & Acer's make use of teh status lights and beeps to warn you that your lamp needs replacement.

NEC VT47 lamp won't light


According to the manual, yes . . .probably gone past the recommended hours of lamp use. Press the OFF or the HELP button on the remote for 10 sec, this will reset the lamp hours value and allow the unit to come on. If it don't, NEC will tell you that it has to be sent to a repair center.
