Flashing red status light on NEC VT45 projector

There is a flashing red light on our school's VT45 projector. The lamp has been replaced but the flashing red light remains. Any suggestions to try?

I have the same problem on the NEC VT 440... the machine actually dropped and the light came on..... we are desperate to find out... I have opened the machine up and made sure all of the connections are tight but still have the problem

i have exactly the same problem with my 440. i dropped it but the bulb etc. seems fine, yet it still flashes red and wont turn on. i don't have a remote to try the pressing and holding "help" button option. is there anything else i can try?

there is a tiny button which is activated by the filter cover, letting the (NEC VT440) projector know the cover is in place. my button is broken, so the projector thinks there is no filter cover and won't switch on. i got it to work for a while by blue-tacking a paper clip inside to hold the button in place, but it stopped working and is very fiddly... is there any way of overriding this safeguard? it's especially annoying because i know the rest of the projector works fine!

Does anyone know how I fix my VT45 if the orabge lite is constant with an 8 second red flash. I think thats "fan error". The manual doesnt say how to fix these errors. The fan appears to be working, and the fan door is snug. This projectore has worked flawlessly for 6 years (mounted to ceiling). I presses the help button on the remote as advised during start up and shut off with no response. Any othewr ideas. When I start the projector I hear a series of tiny clicking noises. It almost sound like the igniter on a gas grill, only much quieter. It does it a few sets of times, then the projector goes into shutdown mode.

Press and hold down the help button on the remote pointing it towards the projector for at least 10 secs.

Red power, blinking red temp

Hi,

if the Lamp error and Temperature error lights are flashing red this means that there are two separate errors.

A flashing lamp light means the lamp failed to ignite. It could be a lamp driver problem or lamp failure. Replace the lamp to resolve the issue. If the issue is not resolved, then service the projector.
A flashing Temperature light signals a fan error. Turn the projector off and allow it to cool down. If the light is still flashing after the projector is turned back on, service the projector.

Goodluck..

Red lamp or heat light is flashing while projector is off. Can't be sure which it is because it is mounted 16' up. I've cleaned projector & filter with canned air from 12' ladder and red light stops...

Hi,
Here is some information on this model which I hope will help...
The lamp indicator lights when the lamp is due to be replaced. It will flash if a circuit abnormality is found.
The temp indicator lights if an abnormal temperature is detected. If it goes too high it will shut down flash.
The lamp indicator is furthest away from the power switch if that helps.
If the lamp timer was approaching the end of the lamp life you would see a REPLACE LAMP nag screen when the projector is turned on. The fact that you have not mentioned this suggests that this is unlikely to be the problem.
The filters on the model are on the underside. There is a removable panel directly under the lens. You should not use canned air as you are blowing dust into the projector. It is recommended that you use a vacuum cleaner. Filters should be cleaned every 100 hours and replaced when the projector is relamped. You can wash the filter by hand with water only, ensuring it is dry before replacing it. Do not run the projector without the filter in place.

Replaced both bulbs with brand-new bulbs. Now all

Verify that the lamp doors are securely closed. The blinking red lights indicate a lamp problem. In this case, both appear to be defective. I doubt that the lamps are the problem. double chack all connections and doors for proper seating. Update this if the problem remains.

Thanks,
Dan

Steady red status light on NEC VT45 projector. Would not POWER ON. LAMP was replaced with a new one

the power supply on that model seem to go bad after a while. the caps aren't properly reted it's power needs. they dry up. if you are good at soldering, replace c1 on the board (big cap) with a cap that has a slightly higher voltage rating. or replace the whole power supply. you might not be able to get one from nec, but you can try www.projectordoctor.com
