Just in case anyone else stumbles upon this I thought i would share the solution I found since I never saw a solution anywhere else on line. After resetting the receiver to factory settings, I connected my receiver directly to my router via ethernet to establish a network connection. I then downloaded the Marantz iOS app to my iPhone. Connected my phone to the receiver via Bluetooth. Usend the app to search for a firmware update and initiate the install on the receiver. Took about 40 minutes for the firmware update to install, but that fixed it. Reconnected the receiver to my home theater setup and thankfully all video and audio is now flowing again to my speakers and my ceiling projector.
