I have an InFocus IN104 XGA projector, and its just started playing up. When its powered on, it starts up as normal, and then after a short period of the lamp being on (varies, initial time might be about 15 seconds, after that might be only 5 seconds). Both fans are running, there is no filters so nothing blocking airflow... I checked it again, after it shuts down it won't turn on again until its been left disconnected from the power for a few minutes... and when it shuts down the temp and lamp lights don't turn on... it just hard shuts down, which leads me to wonder if its a component issue, maybe a faulty power supply Cap or something like that? Any suggestions?
