SOURCE: Infocus x1a projector shuts down after 30 seconds - dust problem ??

Most likely, if it is a thermal problem, your main cooling fan has quit or is stopping after a short period. The problem is, I've seen several of these do this, and in every case, it is not the fan that has failed, but the Controller Board. And that is a very expensive part.

SOURCE: Projector turns off after about 30 minutes. What's wrong?

your projector status means the protection circuit is working or the lamp is in an abnormal condition.
--wait until status indicator goes out and press power button.
---if the above solution is not working change the lamp.

Hi terry2421

No this is not the bulb. You will have to get the Mainboard repaired at a service provider. Losing signal and a discolouration showing up is a clear indication of a faulty Mainboard.

Get a quote first , because some service providers overcharge on these sort of repairs. The most you should pay is $150.

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.

I'm having the same problem. My Model is PB8253. Projector started, then afer a couple minutes it goes off with the red lamp led flashing.
Just replaced the lamp, but the problem persists. Tried to remove all connecting cables, except for the power, but still the same problem.
Anyone with similar problem or solution, please contact me at dartveiga@gmail.com

Infocus LP725 projector


The Projector will turn off after so many hours of running the same bulb module. The counter will turn on a replace bulb LED. Installing the new bulb module should reset the counter and turn off the LED.

Check the projector’s lamp to ensure that it is securely connected
in the lamp module. Make sure by removing it and reinserting it.

Check the cables for problems.

When testing, power up in this order. Projector, Computer monitor, Computer.

A minor power surge may cause the lamp to shut off. Turn the
projector off, wait at least 30 seconds, then turn it back on.

I hope these suggestions help
