Dell 3400mp Lamp error.

I have a Dell 3400mp that gives a Lamp replacement error when it is turned on. We bought a new lamp for it and replaced it but it still gives the error. What else could be causing this?

    I agree with the ballast defect theory. Is there any way to repair or replace it? There has to be - it's a common technology. Every florescent light has one....

Inside the shell that holds the lamp assembly the bottom of the lamp power connection had shifted out of position in the bottom of its harness. I had to remove the projector top to firmly reseat the bottom power connector in the correct vertical position in the harness.

Lamp light shows when ballast (power supply) or dc/dc converter is defective.

WE have a projector that works for 15 or so minutes, then the lamp shuts off. Is that a warning sign that the lamp is failing and will soon need to be replaced?


Hi

Well you can turn on the option by browsing the menu option with system setup. And at the same time do give rest to the projector after continuous use. And do not waste lamp life. In some cases the GPU (Graphic Processing Unit) also malfunction. Hence check to make sure about this as well. And also make sure you have not set the time of shut off.

I bought a replacement lamp for my 3400mp dell projector and I cannot get the pin to seat in the receptical. My old lamp goes in and out like butter, no problems. When I try to put in the new lamp the...


Hi Patrick,

It sounds like you have a damaged or incorrectly supplied lamp. You have established that the old lamp can be fitted and removed easily. You should not need to do anything when fitting the replacement lamp that you did not need to do to remove the origional. Compare the two lamps side by side and see if you can spot any differences. Perhaps some careful measurements may help.

Lamps should have a part number which will be common on both lamps. Non OEM lamps are supplied in re-manufactured housings, the better ones (eg Diamond & Pro-Gen) use the original lamps which are either Phillips or Osram. Cheap copies use 3rd party lamps which are less effective at best.

I would advise being wary of the source of this lamp if it is not Dell.

Not turning on


Sounds like you need a new lamp. Do you have any indicator LEDs "on" near the power button?

Indicator showing LAMP. Does this indicate the lamp needs replacing?


Yes. The lamp is timed and the replacement indicator signals when the lamp is near end of life. If the lamp fails catastrophically it makes a mess... best to replace before that happens.

Projector projects red screen.


My take on this...if that pin was *shorted* to another pin in the connector and not just bent, you could be looking at a damaged video input section. The pins in the video connector consist of the 3 color signals(red--green--blue), their individual grounds, and syncing. If this has indeed happened, which is *VERY* easy to do, the projector must be repaired by a service facility.

Dell 3400mp Projector is flickering


Hello. Based on the video, return the projector and get a new one since it is still under warranty. The symptom has nothing to do with the lamp or connections. It appears to be an image processing problem on the main board. The blank part isn't distorted or scrambled, it's MISSING!
