Two possibilities:

1) Air filter is clogged and preventing proper air flow

2) Lamp is getting old and is less efficient, creating excess heat.


For option 1, check the air filter located on the bottom of the projector. Page 81 of the manual details this process:

http://www.wrcs.k12.mi.us/Technology/How%20Tos/Ceiling%20Projectors%20PGC45X.pdf

Once you have removed filter,either replace or clean out with vacuum or simply blowing out the dust

Option 2: if you have used the projector for over 1500 hours, there is a good chance the lamp is close to the end of its life cycle. Check to see if the lamp replacement light is on; it is just below the power button on the unit.

If you are feeling adventurous, you can take out the lamp by following the instructions on page 86 of the manual: http://www.wrcs.k12.mi.us/Technology/How%20Tos/Ceiling%20Projectors%20PGC45X.pdf

Once removed from the unit, see if the lamp has any bubbles or crystallization. The crystallization makes the mirror in the lamp look muddled, rather than crisply reflecting light.

Hope this helps.

Clean the filter on the projector. Sounds like limited airflow causing the projector to overheat quickly.

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.

Toshiba xp2 projector overheating

Better late than never for any other XP2 owners out there. I've gone through 1 lamp so far with very good results. The key to overheating is cleaning the fan out, i.e. it sucks in a lot of dust particles over time which accumulate on the fan blade and in the vents blocking good airflow. Take a good strong vacuum hose to every vent, then again right when you turn it on. This will get the fan up to speed quickly and assist with removing more dust internally. Eventually, you'll need to open the projector up and clean internally (carefully), but doing the above maintenance will prolong its life and extend the lamp too!

It over heats too quickly

Use a clean cloth to hold the bulb when replacing it. Our hands have oil and dirt. This would cause the bulb to overheat.

New bulb worked for a short trail run now wont light up. flashing green led colour wheel is turning on start up

when you changed the lamp, did you blow the dust out of the projector? if the screen on the side of the lamp is blocked (i.e. with dust), the lamp will blow quickly. if the projector were to overheat, by the fans not running or blocked vents, everything would shut down and the led would blink red.

Optoma projector overheat issue - fan comes on but switches off

Most projectors have air filters. Yours may need to be removed and cleaned. No air flow = overheat.

My cinego when it gets past hot, it turns off

There may be a problem with one of the three cooling fans no longer functioning. There are two fans on the right side (if you are looking in the same direction as the projector is projecting) and one on the left. If even one doesn't function, the unit will too quickly overheat. It must be sent in for repair, in that case.

XB31 projector overheat

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 !
