Summary: Just joining the crowd. I bought this receiver in January of 2012 to replace a TX-NR500 which lost it's back speaker capability, no big deal since that receiver didn't have HDMI capability. The sound quality was very good with the Bose speakers I own. One week ago it hesitated to put out any sound for about 30 seconds, that was the last evening it worked properly.
Summary: I purchased one of these in November of 2011. It was priced well with many nice features. I tried to watch a movie recently and got no sound, nothing. I tried all of the other components I had hooked up to it - same thing. I hadda AKAI Receiver for over twenty years that still worked and this thing quit after a little more than two? What junk! I'm trying a Denon AVR-X1000, hopefully it'll last more than three years!
Summary: Clearly this is a known issue at this point. The reviews are full of this same issue, and internet forums as well. I guess we know why it only comes with a two year warranty. I've got an old pioneer stereo receiver that is more than 15 years old and still works like a champ. 2.5 Years is not long enough for an almost $300 dollar piece of equipment!
Summary: Welcome to the pi**ed-off Onkyo product owner's club. Like many of the reviewers on here, my Onkyo TX-NR509 stopped producing sound. It's been about 2 years and a month since I purchased it from Amazon. I'm extremely disappointed Amazon continues to sell this item. I emailed Onkyo customer support regarding the issue, but don't expect a response based on other users feedback. They are notorious for awful customer support. It's going in the garbage this week.
Summary: Sound went out. Did some internet research. Found this: https://www.youtube.com/all_comments?v=pV_Jbh1ZHVc Based on what I read, I won't try getting it repaired. It will be cheaper to get a new (different brand) receiver.
Summary: I have two Onkyo receivers. One completely died slightly after the two year warranty. I called customer service and they said that for my issue they would authorized an out of warranty repair if I e-mailed firstname.lastname@example.org, which I have done. Unfortunately, they haven't responded to several e-mails. I expected a better quality product and better support.
Summary: The unit was fine for about 6 months. Now it no longer connects to the internet therefore I can's use the internet functions. Contacting Onkyo is next to impossible. They have no way of contacting them online and they are open 9-5 est M-F. I work and MOST people I know are at work during those hours!!!! Taking time away from work to deal with a defective sound receiver is not acceptable. I expect them to have hours that are more amicable to their customers.
