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.

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

TV turned off by itself one day. I pressed reset, timer light blinked green for a minute, then I pressed power and it sounded like it wanted to boot up, but nothing happened and the status light turn


Two thoughts:

First is this is a DLP set and the lamp may have failed

Second is it should have the self check which reads error codes---most of these sets that is the same:

" After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
(then release both)

The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected
This is for a earlier Mitsubishi DLP but should be the same as your set as Mitsubishi rarely changes things like this.
If you get the lamp abnormal it is likely your problem.

RED FLASHING STATUS LIGHT


Possible lamp failure but lamp light not status should blink-I have suggestions but want you to try the self check first--if set has been unplugged plug it up and turn on and when it fails:

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.

Does a lamp error message (6 blinking red status lights) mean the lamp needs to be replaced? or could something else be wrong.


According to NEC technical support, if the status light flashes red six times, this could indicate a defective lamp. If a new lamp is installed and the project still won't turn on, the projector will need service.

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

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.
