Has anyone ever had an issue with their projector shutting down. I'm not sure if it's over heating or their is some other issue, but after 20 minutes I am left with just sound from the dvd.

Cathy,

When was the last time the projector was cleaned? Dust blown out from the fans, etc. What is the air circulation like around the projector? Does it feel abnormally hot (if you have access to it)? Shutting down like that, first thought is over-heating in one of the components. Either power supply or the bulb.

Note that if you are go to 'blow' out the dust, you should use compressed air - no moisture. Make sure all the cooling vents are clear.
