NEC VT470 projector - lamp won't turn on / red blinking status indicator

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.

SOURCE: nec vt470 lamp does not come on. replace lamp,

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.

SOURCE: I have replaced bulbs in 3 different types of NEC

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.

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

Mitsu hc3000 problem "red-green status light blinking and no input"


Heres what the manual says about REd / green lights

Unplug the power cord from the wall outlet and contact your dealer

And also this:

Check that the lens cap is removed.
It may take about one minute for the lamp to light up.
The lamp fails to light up on rare occasions. In such a case, wait for a few minutes
and then try again.
If the projector was turned off before the lamp was cooled down suf? ciently last time,
the fan may start rotating and the POWER button may not work after the power cord
is plugged. After the fan stops rotating, press the POWER button to turn back on the
POWER indicator.
Check that the intake vent is clean.
Set SCART INPUT in the FEATURE menu to OFF. (See page 25.)
Check that the lamp cover is closed. (See page 33.)
Check that the cables connected to the external devices are not broken.
When an extension cable is being used, replace it with the supplied cable for check. When
images are displayed correctly, add an RGB signal ampli? er to the extension cable.
Check the operation manual of the video device for its connection.

Status light is blinking red, power button orange nec vt700


Hello
Look at the number of blinks of the status light.
[1] 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.
[2] 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.
[3] if it blinks at 4 cycles (0.5 seconds ON and 0.5 seconds OFF): Fan error. Fans sill not work correctly.
[4] 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.
[5] 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.

Nec Lt245 power light yellow - orange status blink red, no image, no light coming out of the projector


- Unplug the projector for a full 4-5 minutes.
- Plug it back in and wait for the ready light and try it again.

If the above fails, replace the lamp.
If that also fails, it is likely a bad ballast.

Thanks,
Tor

Power light flashin orange, status light flashing red on WT610 NEC


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.

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.

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! :]
