I can not get the OSD to display on the TV and the receiver continually says that the DVD connection is analog when it needs to be opt1. It had been working last week and now it won't play any sound for a movie or a cd. The display selection will allow me to switch to opt1 and then it resets to analog after a few seconds. I've tried resetting twice with no luck on getting the OSD or the input signal to be correct. Any thoughts/ideas?
