Same issue - my new Q80T controls my Denon X3500h amp fine with the exception of turning on the amp's power. I spoke to a Samsung customer service person and he didn't think that this problem would ever be fixed. Now I need to decide whether or not to return the 75" TV and buy another brand based on this issue. To make it worse my installer told me not to by a new Samsung because he had expereinced this issue, and I assumed that it would surely be fixed. I am really dissapointed in Samsung.
