Take everything apart ,use compressed air on all components ,then take .the internal fan for the lamp, out, clean it really good, try to get every little bit of dust ,that you can see ,then you wont have any more problems of overheating,until more dust builds up,then youll know what to do.

You can also try blowing the dust out of the internal components. I had an over heating problem and took a dusting canister to it. The first time I did this it continued to over-heat so I took the whole thing apart and noticed that I had missed a small fan that resembles a turbine engine. This little fan blows directly into the light bulb. Once It was all clean, the overheating problem was solved.

Hey,

I think it's the cooling... Because when i let it cool down after it shuts down for like a few minutes I can boot it back up. But if i try to boot it up right after it shuts down it won't let me. I think it has a built in temperature monitor to make sure it doesn't overheat. I'm going to install some computer fans on the vents of the projector to get some more airflow. Hopefully that will do the trick.

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!

My benq projector turns on for a few minutes (light and fan going strong), then it shuts down.


if it goes through shut down mode (lamp first and fans run a while), reset the settings to factory default. while you're in the menu, check the lamp hours (under settings). if they're close to 2000 hours, replace the lamp. if the projector shuts down immediately, fans and all, you have a power supply problem. you'll need to replace it.

My InFocus LP650 seems to be overheating, but only the lamp. It runs perfectly for about 20 minutes and then the lamp shuts off for about two minutes and comes back on. During this time the projector is...


I would replace the fans with a higher CFM fan. You can google the size fan you have and something should pop up. The stock fans are about 20CFM. You can get fans with over double that for about $5. Let us know if it works!

Projector shuts off after about 45 minutes


Just a long shot, but...

I have an epson 9000i that did the same thing. Turns out that unit has a small fan (I think 60mm) right next to the power supply to keep it cool, in addition to the large fan that exhausts past the lamp. The fan runs non-stop as long as the unit is powered-up for two reasons I can think of - keep the power supply a little cooler, and the lamp a little warmer so there's not such a temp difference when it powers-up. Long story short, that fan had died. I replaced it with an aftermarket 60mm fan and it's been working fine ever since. Hope this helps.

Compaq MP2800 Lamp powers down after a few seconds


Hi Wayne

It is normal for the lamp's fan to start running , but should actually happen within 15 seconds of starting up. Try changing the lamp's fan and if the problem still persists then you will have to replace the Ballast ( lamp's powersupply )

Lamp goes out


Check your fans, sounds like a thermal shutdown. The fans are 12vdc with a sense line. Red and black power, blue is the sense line. disconnect the fan connector and check the fan with a 12vdc supply. then check the sense line for signal feedback.

I would call Epson support. Sounds like you have an internal fan problem.
