I know this may sound dumb, but...

I had the exact same problem with a brand new HK receiver. It turned out that I was being careless about which ports I plugged the HDMI inputs into. The HDMI inputs on the back of my AVR 1700 are numbered backwards from what seemed natural to me. (right to left instead of what I expected, left to right). All is well now.

Anyway, in case that helps someone, I thought I'd mention it.
