So when that happened, I called Onkyo and they said take it for repair.
Unfortunately, there was apparently a bad batch of 606's that were released. The problem is with the HDMI daughterboard in the AVR. Mine was not the only one at the repair shop either. There were two others with the same problem on the counter when I dropped mine off.
I've been using mine for 13 months with no issues. I hope it's safe to assume that mine is not part of that bad batch.
