I'm with Greg on this, I've had both of those problems individually on different VT4xx's (having both a number of them and a working knowledge of screwdrivers, figured out what was up by process of elimination). Sometimes bulbs die early - if it's really early you might want to see if there was any warranty period remaining on it - and the power boards in these projectors do sometimes break down. They were built in an at-risk period for having troublesome power capacitors installed into them, for starters...

If you are e.g. at a school which has several of these projectors issued to individual teachers, organise to swap the bulbs over between both your units and see which, if either of them, still work afterwards. If theirs was originally working, and after the swap, both are dead, you've got a dead bulb AND something else wrong with the projector, POSSIBLY but not necessarily that PCB. If yours then works but theirs doesn't, it's the bulb. And if there's no change, then both bulbs are good but your projector is toast.

And if it turns out that it's a projector fault, unless either you or an in-house tech can investigate and do the fix either for free or very cheaply, it's probably not worth getting it repaired. These models are really quite old and under-spec these days, and you can replace the entire thing with a brand new model of similar specification - with a working bulb installed! - than it would cost you to buy a single replacement bulb for the NEC.

SOURCE: 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 ..

SOURCE: I have a NEC VT470

steady orange means projector in standby mode
red light 6 times is a lamp error.
either the lamp is old and wont start up or the ballast power pcb is not working.
can you hear the sparking of the high voltage trying to strike the lamp.
if you can then the lamp may be dodgy.
can you borrow one to test it out

Nec vt470 lamp does not come on. replace lamp, when turned on status light turns red and get 3 beeps. lamp does not come on.


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.

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.

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.

NEC VT47 Blink Sequence but not comming up.


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! :]
