Starting having issues with my Ben-Q HT1085St projector. It turns on and plays fine for about 30-45 minutes. then completely shuts off with the power and temp light turning a solid red.

I went ahead and purchased a new OEM Lamp from to see if that would fix the issues. it did for about two full movies then started the same thing, play for about 30 min then shut off with the two same red lights.

The projector is mounted on the ceiling in my theater room and is well ventilated.

Hello Timothy,

Sorry to hear about the projector shutting down on you. It could either be dust/dirt buildup or a fan starting to malfunction.

Do you know if you are still under warranty? Please provide your proof of purchase.

Thank you
