Problems with keeping the projector on!!

I turn on my home theater and everything turns own including the projector. However, 3-5 minutes later the projector turns off. The sound and everything else stays on. Finally, the status light blinks constantly.

Theatre projector is unable to switch inputs in menu

This is worth a try: Turn everything OFF. Unplug all the inputs from the projector and turn them off too. Next, turn the projector ON and all the input devices ON. Then, one by one plug each input device (already turned ON) into the projector. See if this helps. I have a SONY monitor that supports multiple inputs and a few times this has worked.
Good luck.

This is most likely a problem with what's called "HDMI handshake." It's a silly protection scheme called HDCP that is meant to keep people from copying content. The best thing to do is unplug everything, then turn on things in this order: receiver>projector>sources (directv, Bluray). If that does not work, check for firmware updates for the receiver or projector.
