I think you have to Reset the lamp every 800hrs or 1900hrs I think you are to late now just get a new lamp.

Re: NEC Projector

They have a fuse on the power board inside the projector itself, But normally the fuse does not go bad unless their is a dead short in the unit.

The projector turns on but won't project any light through the lens.

If this is a NEC VT series projector, Change the lamp. When if it continues to blink amber and not project and image after installing a new lamp check the lamp cover to see if the micro switch tab on the lamp cover broke off. Some models have a built in lens cover. If the cover is not slid over to open completely the light may not turn on.

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.

NEC VT695 (not a vt570) bad lamp blowing ballast board?

We have the same model here at our school too. I know of two that have done exactly what you said. I am trying to figure out if this is NEC fault. Bulbs are expensive and if the projector and NEC is a fault; we will definitely be moving on to a different brand.

250V T6.3AH Slow Blo Fuse

Depending upon the way in which the lamp finally smoked, it is not unusual for the feeder fuse to blow. Replace the fuse and try the projector. As long as you haev a new lamp, it should work OK.
