I'm new to these forums and fairly new to Denon A/V receivers. I flipped on my Denon tonight and it stated that there was a firmware update available so I decided to update. Well, it allowed me to watch TV while it just said authenticating forever so I flipped the A/V receiver off to cancel the update and do it at another time. Now, it doesn't display anything or any sound and is stuck in this "update retry" mode and I can't get it to work. It worked fine and I should have never even updated it. I need help resetting it or getting my brand new receiver to work again, very frustrated.
Any help would be greatly appreciated.
