I don't think it's related but, my Directv receiver will not come on unless the projector is on and the 990 is set to that input. You can push the power button on the remote or the power button on the receiver and nothing happens - just like its unplugged - switch it on last and it works fine. You can change the 990 input after its on and it doesn't seem to care - just on start-up.
