Infocus LP790 projector suddenly shuts off after 15 minutes of use

Hi, I have an Infocus LP790 which occasionally, and suddenly, will shut completely off after 15 or 20 minutes of being on. The whole projector shuts down - no fans or anything remains on. I restart it and it might happen again after 15 minutes or not and run fine. Any thoughts.

    This exact thing happens with my Dell 2300. The lamp indicator says it has 800 hours left.

Projector is overheating. Turn the projector off and let it cool for 30 minutes.
Clean the air filter and check all ventilation holes for blockage.

Hope that helps..........

are the leds on the top lit or blinking? it could be the lamp, the ballast, or the fans. check the lamp. if there are black spots or bulges in the lamp, replace it. if not, make sure the fans are running. if they are, replace the ballast.

if no fans will come on, it's the power supply. if the fans come on but no light, it's the colorwheel or the ballast.

the projector thinks it is overheating. you may need to replace the temp sensor. it located near the lamp plug. also make sure the fans are both moving.

Infocus LP530 will turn on and work great for 15 minutes then shuts down and the green light turns orange and blinks. The Bulb only has 283 hours on it.


The ambient temperature in the room is to high.
Try lowering the room temperature. If that doesn't work get a small fan and place it near the projector ro provide extra cooling. The projector is running border line on high temperature and just needs a little extra cooling.

DLP Infocus Problem


first of all, the infocus lp 790 is an lcd projector, not a dlp. second, the light filter in front of one of the lcd panels is burnt, and unfortunately cannot be purchased separately.
