1) First thing could be that depending on the location where this is installed could be altitude related as some projectors run differently at higher elevations with thinner air/humidity.
2) If this is not the case then then most likely the thermistor placement on the inside of the projector that detects the internal temperature to protect the internal hardware has moved or is defective. If this Thermistor switch has moved slightly this problem occurs. The solution is to send it in for inspection and adjustment.
3) There is either a fan disconnected internally or one of the fans may have gone bad. Solution is to send it in for inspection
Hope this helps

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.
There is a lens/lamp filter which must be taken out and cleaned, use good air jet to blow and brush out dirt. If the filter is clogged then the lamp might heat up and so shut down..
if the fault does not clean try and force cool the unit, if not there is fault in the power supply, possible lamp problem or circuit error on load or heat.
You will need to open and use a test bench to check out the sections, one by one, use of multimeter and good equipments may be needed . If not take help with consensus.
If you are connecting to a laptop then you may need to hold the function button down and press F1, F2, F3 etc. there should be a sign with the latop on there and a sign with an external device (monitor,PROJECOR)
hope this information was useful to you.
blow the dust out of the projector using canned air. if there is too much dust, the projector cannot stay cool and may damage components and lamp. the shut down is a protective measure. also make sure the projector is not too close to heat sources and that the vents are not blocked. then check the fans to see if they are working. if after that it still does that, you may need to change the thermal sensor. it may be bad.
Just a quick couple of notes about your projector. It is a DLP projector (not LCD) and as such the machine as no air filters to clean. It does have air intake and air exhaust grilles, but no air filters to clean. This next part comes directly from the owner' manual for your projector:
When the lamp operation time exceeds 2000 hours*1 *2, the projector automatically shuts off and can’t be used until the lamp is replaced and the lamp operation time is reset.
Your machine is designed to give visual warning messages at 1500 hours used, and 1900 hours used. Did you see any visual warning about lamp life over the past few months?
If you were experiencing an overheating problem, a "TEMPERATURE!!" message would flash up on the screen just before the unit shuts down. If there is no warning, you don't have a heat problem.
If you have a replacement lamp available, install it and reset the lmap hours according to your user manual. If you don't have the manual, google it on the web (it available).
There is a heat sensor cutting down the power. The sensor is located on the upper side between lamp and fan and is monitoring the air temperatur. I don't know what is causing the sensor to switch - excessive heat or simply age or ... . Anyway un screwed this sensor and my problem disappeared.
Possibly a stronger fan would solve the problem too.
