Hello fellow 4520 owners...
I have a situation where when I connect my Denon to the TV I see the Denon logo and everything seems fine including sound playback.
When I play music using airplay I see the art label on the TV.
However when I connect my Roku or Apple TV it says "no signal". I even tried connecting that using a Ethernet hdmi extender thinking I may have a lengthy hdmi cable.
I've tried connecting both of these devices on multiple inputs but same result.
When I connect the Roku or Apple TV to my Marantz 5008 they show up fine on the tv with the same HDMI cable. So I'm kind of leaning towards that the hdmi board may be bad.
But if the hdmi board would be bad should I expect to see the Denon logo and airplay stream screen? Or even for that matter the setup menu etc?
I have tried the factory reset pressing menu and back buttons technique multiple times.
Any help is truly appreciated.
