    Yes lamp specs are the same but i dont have the remote control. Does this mean that the circuits are good inside the unit because the status lamps are working ok?
    can the reset be carried out without the remote?

    Thanks for that, please can you advise how to check the lamp with a meter and what the power supply and rating should be from the
    unit to the lamp.
    This unit does not run now just the status lights. I have checked the lamp is correctly installed and no wires are off.
    Must i have the remote for reset ?

Hi,


I just noticed that the power light will light orange and the status light blink red if any of the external dust filters are not in place. There are little switches that tell the projo if they are missing. So, double check that the filters are in correctly.

Is the fan running properly or are any vents blocked?
Sounds like it is overheating.

Might just be that the thermal cutout is going bad inside the unit. Shutting off at to low a temperature.
Sounds like the most likely cause. They do change properities as they get older.

Goodluck..

    I believe this indicates a lamp failure. Make sure the lamp is seated
    correctly. If you haven't checked, take the lamp out and look at it. I
    left off a connector (the yellow wire I think) once when reassembling ur projo and had what I believe was the same indications. If you have
    taken the projector apart double check that all the wires are
    reconnected.

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.

I have a NEC VT470 Projector. The power light is steady orange and the status light blinks red 6 times.


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

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!

No lamp and a flashing red status light


The lamp has run out of its operating hours which is normally 3000 hrs. Replace the lamp and you will be alright.

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.

NEC VT47 Lamp type VT70LP will not power up 2 red lights spear Lamp not working


When the lamp exceeds 2100hoursof 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! :]
