Summary: My 5008 lasted 20 months before having the same problems as everyone else. I had to send it in for repair. That was 3 months, 2 weeks ago. I still have an old Yamaha sitting where this 60 pound beast sat. The sound doesn't even come close to the Onkyo. If it were not for the problems I am having, I would give it 6 stars. I won't go as far as saying don't buy one, because if you get one that works, you will love it.
Summary: I ordered the Onkyo tx nr5008 for my new dream home theater. Within 3 months the receiver began cycling through all of the listening modes with no sound at all. I called customer support and after jumping through all the required hoops I was told that my new "FLAG SHIP" receiver would have to go in for service. When I got the 55 pound beast there the women there pointed to racks of Onkyo receivers with the same problem .
Summary: This unit worked well, as others have documented, for a year and a half. Last week it started to spontaneously switch function to the Cable/Sat input, regardless of what I selected. I unplugged it and let it sit for a few minutes, and it worked for a little while longer. Now it is stuck on the Cable/Sat function and none of the panel controls or remote controls function.
