Re: Infocus mod.610/620 Lite pro
It may be reaching its max temp and shutting down to avoid over heating or popping the bulb. How is the air ventiliation and room temperature? You may also want to browse through the settings or check for a switch on it, to make sure it isn't set to go into a stand-by mode after such a short period of time.

I own two of these projectors. You need to update the firmware to 1.03 which can be found on the infocus website. This solves the fan issues which also causes premature shutdown of the projector. Once you download the update, open it, there will be step by step instructions on how to do this procedure. I could not get this to work with Vista 64 so you might need to run this on XP or 7.
the Projector unit may be overheating due to airflow. ensure that the intake filter is not blocked, remove and clean it and then replace do not run with filter removed as this will cause dust inside your machine. check that none of the airflow slits on the body of the machine are bloced or taped over. check that the unit has enough airflow around it to keep cool if unsure move the machine to a open space and let it run to see if the problem persits or stops.
if this persists it may mean the overheat cut off switch is defective and keeps activating even though the machine is not overheated.
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.
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).
