SOURCE: Status light blinking red

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! :]

SOURCE: Blinking status light

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.

SOURCE: NEC VT 595 wont turn on. Just red blinking light

I had this same problem with 2 NEC VT595 projectors. My problem was that there was a broken "tab" on the lamp cover (the plastic cover that slides in place over the lamp) that is supposed to depress a switch which insures the lamp cover is in place before operating the projector. The tab was broken in half and not making the connection there for causing the blinking status light (.5 sec on, 2.5 sec off) indicating a lamp housing or cover error.

Hi I am having trouble with an LT180 DLP I'm getting a series of error messages culminating in the power light steady orange and the status light flashing a series of 6 flashes red. Inside I found that...


both lights flashing green indicate the projector lost power while it was running (didn't get to go through shutdown procedure). if the status light blinks 6 times, the lamp is failing to strike (one time means the cover is open, 2 times is a temperature issue, and 4 times is the fan). if it comes on and shuts off a short time later (less than 15 seconds), the ballast is going bad and needs replacing. if it didn't come on at all, it'd be either the ballast or the colorwheel. if the lamp light was red, it would be the lamp that needs replacing. nec won't sell parts to anyone who is not an authorized nec service center, so you'd need to contact one to get the part (although they may not sell it to you). but good luck!

Green status light keeps blinking after lamp replacement


continuous blinking green light indicates that the capacitors have failed on the DM pwb. You need the V26 DLP DM repair kit which is available at the following link under their repair category.
