Summary: It completely died after just four years with a bad HDMI board. I spent $500 on this and spent another $60 on replacing the remote suspecting that could have been the problem. In the end, one after the other, the receiver was shutting off and then it stopped working completely. It is trash now.
Summary: I have very little to add to this discussion that has not already been explored. I just wanted to throw in my voice to say that I am now undergoing, as so many others have before me, the "no sound" issue. Furthermore, judging from the overwhelmingly negative fates of this receiver, I will never purchase an Onkyo product again. I will not be repeatedly suckered by poor workmanship and reward a company by giving them my returning business.
Summary: What a piece of garbage. Unit broke under the original warranty, repaired. 2 Months after warranty expired, exact same problem - onkyo made a "courtesy exception" and repaired the same problem again. A year later - guess what - same problem for the 3rd time. Onkyo said "sorry, we already fixed it as a courtesy once, would you like to buy a refurbished unit?" I've never had such poor experience with a $500 piece of AV gear.
Summary: Like others my 707 stopped working (no sound) after two years. It started shutting down, and then it would come back on a couple hrs later. Then it would shut down and take a day, then several days to come back on, utill after 7 or 8 days it died for good. I tried everything to revive it, but nothing worked, after a week of trying I gave up. Do not buy Onkyo Receivers, unless you plan on useing one as a cheap temporary replacement for another brand.
Summary: It died after two years of use. I've seen many reviews saying they had the same "no sound" issues. I went back to using my 15 year old Sony receiver after this died. I won't be throwing my money away on Onkyo anymore. When it did work I had issues with the unnecessary amount of clicking it would make when changing inputs.
Summary: As many other people said - it failed shortly after warranty expiration. I think such a low quality is not acceptable for a high end equipment. Those things should work till they morally obsolete.. Decent while it was working.. But who cares if I need to throw it away now?..
Summary: I bought this receiver back in December 2009. It has died completely within two months, and was repaired under the warranty. Now it is dead again - can't be turned on, no lights, nothing, and I am out of the warranty time. It spent most of the last two years sitting in the garage, not used. I started to use it again just a month ago, and now I need a new receiver. Stay away from Onkyo products, that's all I can say.
Summary: The unit was great when it worked. Great features at an attractive price. All this is moot now as the unit died after 16 months. I get no sound at all. The problem has been reported by scores of users on this site and others on the internet. Onkyo refuses to admit an inherent defective product. Unfortunately, it takes this brand out of play for me.
Summary: As others have stated, the Onkyo TX-SR707 unit I purchased stopped working about 18 months after I purchased it. Extremely dissapointing, and basically a waste of the $565.00 that I paid for it.
