I bought an AVR-790 back in Mar/10, from an authorized reseller. I did not have my TV or bluray at the time.. once I got my setup in place, the 790 worked for a couple of weeks and after 60 days of purchase, it would not output via HDMI.. tried resetting, called Denon customer service, bought new HDMI cables, to no avail.. I went ahead and shipped it for in-warranty repair. Since it was during the World Cup, I purchased an out-of-box 790 at the local Best Buy to take me through the games.. needless to say, within two weeks the unit had the exact same problem..
I returned the out-of-box unit to Best Buy and anxiously awaited for my repaired unit from Denon. Instead of repairing the unit, they shipped me a refurbished 790, which as I feared, after two weeks, it went down with the same old problem.. I tried resetting it, unplugging all HDMI, turning off my TV's HDMI-CEC feature, to no avail... I am at a loss but before I ship this unit back I want to make sure it is not something in my setup that is causing this.. This is what I have:
Comcast HD DVR, Motorola DCX3400 (Which was also replaced on my first 790, in case the cable box was bad)
Samsung UN55B8000 TV
Samsung Bluray player
AppleTV
I have one 25ft HDMI cable going from the 790 to the TV but also tried connecting it with a 5ft one, to no avail.. tried swapping all cables, resetting the unit, nothing has worked so far. I am about to give up on Denon and get another brand.. Is it me or am I incredibly unlucky??
