Receiver Woes

It didn't seem so apparent at first, but sometimes when I'd switch to my HTPC set up, I saw some flickering... usually it would go away on it's own, but I found more often then not, that I would have to restart my mac and the flickering would stop. I assumed it was something related to the mac, but after a slight setup change, I noticed the same flickering from my Roku box. Which leads me to believe my receiver id F'd.

Now this isn't something new to me, I did buy it as an open box item from best buy... and it has already had it's share of issues, often not responding to volume control or sometimes not turning off... Sent an email to HarmanKardon, we'll see what they have to say... Sigh.
