IN104 automatic shutdown


Hello, my infocus in104 will power up for a while (1- 5 minutes) when connected to the power supply and turned on, after that it automatically shuts down. Power button does not light red when it automatically shuts down and need to be unplugged for a minute or more before red power button will light up again.

Epson Projector, Model: EMP-X5, Epson projector shuts down after 30 minutes work


There are several things that can cause this problem, but the first thing I would check is the filter. The projector requires airflow to keep it cool. If airflow is blocked, the projector will overheat and shut down automatically.

Projector will only stay on for a couple of minutes then shuts off automatically. the LED turns from green to red


Make sure the venting for the cooling fan is clear and that it is activating. The only time I have seen this in a projector is when it overheats. If it reaches a certain temperature and doesn't sense the cooling fan being on it shuts down to protect the bulb and protect against fire hazard.

Projector was turned off wrong and now wont turn back on.


if the led flashes once in 2-second intervals and you don't hear a high-pitched whir, the colorwheel needs replacing. if you do, the ballast is bad. if it flashes 2 times, the lamp is past 3000 hours. 4 times, fan error. 5 times, temp too high and it needs to cool.

InFocus LP725 light goes out after 10 minutes


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
