Question about NEC VT470 Multimedia Projector
Power indicator shows standby, status indicator blinks 6 times. I have tried powering on and off. No indicator light showing for lamp. Use projector everyday and haven't seen lamp message appear about low life. Please help I am a teacher and need this resolved.
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.

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
