Summary: This unit has horrible HDMI handshake problems, leading to lots of blue screens and "no signal" messages on the television to which it is connected. This happens so often when trying to use it with an Apple TV that it is unusable for this. The problem seems to have only worsened in the almost two years since I have owned it, but it was never good.
Summary: It has a chronic problem just like the NR616 I replaced it with. It loses HDMI connection. You have to unplug it to force hdmi startup to reconnect. This particular one didn't respond to that procedure either! A reset resulted in having to setup again--- but it in on the screen and I had no video so I sent it back.
Summary: I bought this receiver despite reading in the reviews that it had issues relating to the HDMI output because it had all of the features I need and was way less expensive than the alternatives. I figured that Onkyo had probably resolved the issues by the time I was purchasing the unit, after all it was January 2013 and some of the reviewers said not to pay attention to bad reviews before August 2012. Should have known better. The problems started almost immediately.
** Updated: HDMI problem persists despite new firmware **

Summary: UPDATED: This started out as a 5* review on discovery that I did not need to update the firmware, my unit came with the 400 version installed. But things went downhill since then - now I wish I could assign zero stars, not one. The well known HDMI problem did not magically go away with the new firmware. Yes, there are many satisfied reviewers, and I agree with them based on the feature / price ratio.
Summary: This unit should have been pulled from the market a long time ago. Seemed like a nice set of features, but it drops the video signals from time to time and requires the unit to be unplugged for a reset. I have updated the firmware but this still happens. This is widely known on the onkyo support boards, unfortunately I found out too late.
Do not buy this product - HDMI out issue still not fixed

Summary: This would have been my third Onkyo receiver but I am sad to say that I am returning it and will never buy another Onkyo product. I chose to overlook the negative reviews regarding the failure of the HDMI out. Mine worked fine for the first month but then stopped working. I went on the Onkyo forum where I learned that this problem is extremely prevalent.
Summary: There is a major flaw with this receiver and the TX-NR616. After long periods of standby (overnight) the receiver will fail to deliver the HDMI video to your monitor or TV. The only way to get your picture back is to unplug the unit and plug it back in. Onkyo is aware of the issue and have been trying to resolve it for months to no avail. I purchased one without knowing and experienced these issues. I returned it back to Amazon.
Summary: It stopped working after 5 weeks. My old onkyo broke after 26 months and so I decided to purchase this onkyo product which broke after 5 weeks. I had to ship it to the manufacturer who is currently working on it. It had been there over 2 weeks now and still not fixed. I'm done with all onkyo products from here on out.
Onkyo TX-NR515 Great product!!! BUT FAILS SOON AFTER!!!

Summary: Just a short review because I use reviews to consider all my purchases on Amazon. I liked the reviews on this receiver(almost 4 stars) and have one in my study so I have a history with Onkyo. Always a good product even compared to my fav receivers by Denon. Infact I bought a Denon from Best Buy first and returned it for multiple reasons. First being I didn't like how hot the unit got compared to my older Denon rec I had(non-HDMI).
