NEC VT 470 projector won't work at all

Our school has a NEC projector VT470 and the lamp won't come on at all. It was "dead" when the teacher brought it in. So we decided that the bulb was burnt out and replaced the bulb. I have installed and even reinstalled the new bulb. It still doesn't light. The Lamp light doesn't even come on. I have it connected to a computer but I can't get the green light to indicate computer to turn green either. I turn on the projector and press power. At first I get a green light, next the status light starts to blink green but there it stops. after a couple of minutes, the status light starts to blink red and the power light is orange. What can I do?

Try pressing the HELP button. Don't release and press the power button. The LED lights should blink. Release then try to power on again.

Hello Dear,

It seems like Your projector has a problem with Ballast unit, which ignites the lamp.

Check it.

I have an NEC VT470. The projector shut down after the lamp finished. When I replaced the lamp and pressed the start button, the projector does not come back on.

Some of the NEC units have a standby status when the lamplife has exceeded its safe limit, the unit I had needed the off button pressing for up to 20 seconds to reset the lamplife and allow the unit to be switched back on. There should be info for this in your manual.

Good luck

Replaced the bulb yesterday- the projector does not recognize the change- getting a default message to change it... And there is a strange smell (we also changed the filter (after 5 yrs)

copied from manual
select the menu - default - clear lamp hour meter to reset lamp usage hours.
Note when the lamp exceeds 2100 hours (3100 in Eco mode) the projector cannot turn on and the menu is not displayed if this happens do the following while in 'standby' to clear values for Remaing lamp Time and lamp hour meter for vt670/470 press the help button on remote control for a minimum of 10 secs When the lamp clock is reset to zero the lamp indicator goes out.

As there were no indicator lights lit I focused on the AC. The projectors work as they should in another location and as such I am fairly certain the problem is associated with the AC power in the particular room. I haven't isolated the exact condition as yet.
