Summary: Great receiver, horrible design. I bought the 5007 in May of 2010. The HDMI board failed in 2011, but it was covered under warranty. It only cost me the gas to drive to Huntington Beach and back two times. Not terribly far from San Diego. It has just failed again May 2015.
Summary: What a great unit and a POS. Had the HDMI board replaced under warranty and it lasted 2 months. Now I am on my own. Buyer beware of Onkyo and its customer service. I have bought $15000+ in Integra/Onkyo equipment. All of it only lasting a year. They just burn up with heat problems.
Summary: This receiver is now in my closet and I'm looking to sell it at a discount due to the issue. Onkyo customer service is horrible. They tap danced around the known HDMI board issue and basically made me realize why I should have never left Yamaha to begin with.
Avoid this unit. Probably a good idea to avoid Onkyo entirely.

Summary: Ordered from another site several years ago. As others have stated and numerous home theatre related web forums will tell you this and apparently many Onkyo Receivers have a design flaw. I own 3 Onkyo units of differing models. 2 of the 3 have failed.
Summary: original unit failed within 15 months. had to re-package and pay ($$$) to send 65lbs of electronic junk to repair facility in Denver, co. while they replaced unit under warranty, second receiver failed less than 12 months later and subsequent warranty request denied.
Summary: Like so many other reviews I now have the same sound issue. I just spoke to the repair shop and the cost is going to be over $600.00. I sure wish these reviews were around early in the game but that is a chance you take when you by early.
Summary: It is not recognize my speakers and will not sound at all. Turn it on and off will fix that problem somehow it is getting much harder and harder to get it right. My warranty was expired about 6month ago and it started happen 3month ago.
Summary: Had the exact same sound failure as others are reporting. Unit was purchased Nov 2010 and was a great unit until a few weeks ago. Like others, sound stopped working, but would come back after a hard power down and restart. After doing that 2-3 times, all sound died. Video still works fine.
Summary: I purchased this item in May 2011. A couple months ago, it started to power up with no sound. I would turn it off and then on a couple of times and the sound would click back on. Now 2 months later, this no longer works. It appears that I am not alone in experiencing this problem.
