I lost my HDMI output to my Sony LCD. CSR said to buy a new cable, I did and it still didn't work. Then they said ok we will send another reciever. The HDMI output was ok until it update itself then went out again. They are now sending a third box. Any ideas? Is this a software issue or a hardware issue. The CSR's are useless. All they know how to do is send boxes. I've hard booted the reciever many times and it' still a no go.
