The status light is blinking red every .5 second at .5 second intervals for 6 cycles. The power light is solid orange. Per NEC manual, it says to wait a minute and restart. It just continues the same error condition. I replaced the lamp, same problem occurs. I tried a known good lamp from another projector, same problem occurs. Any ideas? I tried your solution of: For VT570/VT47 Press and hold the power and the exit buttons on the remote control simultaneously for a minimum of ten seconds. When the lamp time clock is reset to zero, the lamp indicator goes out. Same blinking status light. I replaced the bulb and tried again, same blinking status light. I checked the filter, etc. This projector has not run for 2100 hours, so the bulb should be okay. Please help!
Replacing the lamp with an old one was helpful for me. Good news: the projector itself not faulty. Bad news: I have two projectors with the same issue at the same time (the lamps were replaced also at the same time) after only 400 hours of running.

Re: Blinking status light
6 cycle (0.5 sec On,
0.5 sec Off) is a lamp error!
0.5 sec Off)
Lamp fails to light. Wait a full
minute and then turn on again.
Even though the lamp is not old there may be a defect in the lamp. I know the lamps are expensive but this may be the problem. If you have a lamp that was removed due to age but still worked you could use the lamp to test it.here is a link to the user manual: http://www.iusb.edu/~libg/ims/VT570_MAN.pdf

Hello Look at the number of blinks of the status light.  If it blinks at one cycle (0.5seconds On and 2.5seconds OFF) : Lamp cover error or lamp housing error. Replace the lamp cover or lamp housing correctly.  If it blinks 2 cycles (0.5 seconds ON and 0.5 seconds OFF): Temperature error. The projector is overheated. Move the projector to a cooler position.  if it blinks at 4 cycles (0.5 seconds ON and 0.5 seconds OFF): Fan error. Fans sill not work correctly.  If it bliks at 6 cycles (0.5 seconds ON and 0.5 seconds OFF): Lamp fails to light. Wait a full minute and then turn on again.  If it blinks continous (Red): Lamp has reached the end of its life. Lamp replacement messege will be displayed. Replace Lamp with same type and number. After replacement reset lamp hour. OK.
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
if the status light is flashing .5 seconds on and 2.5 seconds off - you need to replace the lamp cover correctly.
if the status light is flashing .5 seconds on and .5 seconds off in 2 - 6 cycles the error is:
2 cycles - the projector is overheated. Move the projector to a cooler location, or/and remove dust in the light path.
3 cycles - the power unit is not working correctly.
4 cycles - the fans are not working correctly
5 cycles - lamp fails to light. Wait a full minute and then turn on again.
If it is a lamp error try this: When the lamp exceeds 2100 hoursof service, the projector cannot turn on and the manu is not displayed. Do the following: For VT670/VT470 Press the help button on the remote control for a minimum of ten seconds. For VT570/VT47 Press and hold the power and the exit buttons on the remote control simultaneously for a minimum of ten seconds. When the lamp time clock is reset to zero, the lamp indicator goes out. Hope this helps! :]
