    this might hold true for a lcd projector, acer pd 112 is a dlp projector, and i was not able to locate the air filter, it is no where near the lamp nor behind or underneath. the fan is a free flow one. thanks any ways for trying

    I replace the lamp of my pd112. A message about the lamp reaching the end of its life keeps flashing. I can't even access my menu. If I press the menu on the projector or remote control, it flashes 30 seconds, then back to the message. I wanted to disable the lamp life reminder.

    What should I do?

What could be the issue if my projector turns itself off after only running for 1-2 minutes?


It maybe a problem with your lamp as they can run for a short while then shut down.
When it shuts down do you get the lamp or temp indicator coming on?

Mitsubishi HC900 Projector shuts down after 5 minutes.


You have 1 of 2 possible problems.

(1) You need a new lamp.

(2) You have an overheating problem.

Just a quick couple of notes about your projector. It is a DLP projector (not LCD) and as such the machine as no air filters to clean. It does have air intake and air exhaust grilles, but no air filters to clean. This next part comes directly from the owner' manual for your projector:

When the lamp operation time exceeds 2000 hours*1 *2, the projector automatically shuts off and can’t be used until the lamp is replaced and the lamp operation time is reset.

Your machine is designed to give visual warning messages at 1500 hours used, and 1900 hours used. Did you see any visual warning about lamp life over the past few months?

If you were experiencing an overheating problem, a "TEMPERATURE!!" message would flash up on the screen just before the unit shuts down. If there is no warning, you don't have a heat problem.

If you have a replacement lamp available, install it and reset the lmap hours according to your user manual. If you don't have the manual, google it on the web (it available).

Projector shuts down after only a few minutes.


I'm having the same problem. My Model is PB8253. Projector started, then afer a couple minutes it goes off with the red lamp led flashing.
Just replaced the lamp, but the problem persists. Tried to remove all connecting cables, except for the power, but still the same problem.
Anyone with similar problem or solution, please contact me at dartveiga@gmail.com
