Question about NEC VT470 Multimedia Projector
I have exactly the same problem, the status light is blinking red, 5 cycle, the manual says lamp failure, "wait a full minute and restart" , I tried it several times but it keeps doing the same. I tried pressing for more than 10 seconds the OFF and EXIT buttons on the remote as well, still no result. The lamp indicator is off. I have not used the projector for more than 1000 hours. Somebody suggested that it might be a ballast problem. What can I do? Have you solved this problem on your projector? Thanks!

Try to reset the projector. Turn the power off. remove the power supply cable from the main socket. Leave it for 30 min. Turn on again. Before turn on(Make sure) 1.0 power cable install correctly 2.0 Lamp cover install correctly. 3.0 No excessive heat around the projector All this can be refer to the user manual.

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.

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.
I've attached an image to help out.

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
