Question about Epson PowerLite 5550C Multimedia Projector

1 Answer

Projector shuts off after about 45 minutes

Our ceiling mounted projector shuts down completely after about 45 minutes of use. No lights are lit - no red light or anything else. No response to restart from the remote or pushing the power button on the projector. After several hours, the red light comes back on steadily and the projector will start up again. Does this sound like an overheating problem? We get no on-screen messages - it just shuts down totally. Is there a filter that needs cleaning somewhere?

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.

Mistub XD450. Bulb relatively new. Projector


Does the projector work normally when sitting right-side up? If yes, something could be interfering when the unit is inverted. The symptom you describe initially sounds like a defective fan (some fans put out a computer pulse telling the main board it's running--they have 3 wires, red, black, yellow(signal)). If the board doesn't get signals from all required components, it's programmed to shut down to protect itself.

How do i mount my hopper projector sv 10 to the ceiling


Yes it should be mounted upside down as you would not want to see the bottom of the projector all the time, unless the bottom is as good looking as the top, which I doubt. I wonder if you bought or got a ceiling mount rack with it. First mount the rack on the ceiling and then fasten the projector to it. And before that its picture has to be turned upside down too.

NO POWER TO UNIT...


yes. it's warm up there. and it's suceptible to alot of dust and dirt. all of that will cause the projector to overheat frequently. also: if you've had to reset it that many times, it's wearing out, and you should replace the bimetal breaker (the little red button).

Optoma H56 - turns off just after start up.


It's not a short, the blub is near the end of it's life ~ the optoma is designed to detect when the blub is about to blow and shuts itself down. Turning the projector upside down or right side up usually only gives you a brief reprieve (some have reported a modest amount of extra time gained) on the blub ~ but in the end it's on it's way out and the projector will shut down again.
