XB31 projector overheat

Hi, well the projector will work for +/- 1h30 then overheats and shuts down. The light indicates overheat, not temperature problem.. in the specs.. anyways, i put a new lamp in and it still does the same thing. It worked for 4-5 hours without shutting down when i tried it with the top cover open at 1 inch.
Thanks for your interest. Marc.

Hi sun_md

This sounds like a typical temp. sensor that is faulty.

If you take off the top cover of the Projector and follow the cables from your fans to the Mainboard - you'll find a smallish board that regulates the heat of the Projector. You will also find another sensor on top of the lamp housing.

Try replacing the sensor that goes with the fans first , this is normally the one giving problems.

Good luck and thanks for using Fixya !

My Epson TW 700 suddenly went black,and the fan startet to go very fast.I could also see the red light ( temp. Indicator? ) coming on.Tried to cut the power, cleaned the filter and start it again, but...


Don't cut power to a projector when you power down. The fan has to run after the projector is powered down so that the lamp can cool evenly. If you unplug or if there is a power failure the lamp will develop cracks around the edges of the reflector and will fail quickly. If the fan is not moving air through the projector, it will overheat and shut down.

Epson Projector, Model: EMP-X5, Epson projector shuts down after 30 minutes work


There are several things that can cause this problem, but the first thing I would check is the filter. The projector requires airflow to keep it cool. If airflow is blocked, the projector will overheat and shut down automatically.

Projectors shut off when they overheat. They overheat when air does not move through the projector cooling it. This happens when the fans are not working or air filters/vents are not working.
Check to see whether the fans are working. If they are working, open the cover and see whether air filters/vents are covered with dust. If so clean them.

Projector will only stay on for a couple of minutes then shuts off automatically. the LED turns from green to red


Make sure the venting for the cooling fan is clear and that it is activating. The only time I have seen this in a projector is when it overheats. If it reaches a certain temperature and doesn't sense the cooling fan being on it shuts down to protect the bulb and protect against fire hazard.
