Summary: After a few months there was nos sound coming out of the CBL/SAT port. I switched to a different port, it worked for a while and then there was no sound out of that one either. As I am living overseas there is nothing that I can do except junk it and never buy Onkyo again.
Summary: Onkyo is total junk. This is my second one and both are broken. First one was an Onkyo HT-R667 and it broke right at one year mark just in time for it to be out of warranty. The hdmi ports stopped working and now it only works with RCA cables.

Summary: Had this receiver and loved it for about 1 year. Started to show the "random input selection" bug I've seen all over the internet. The receiver basically randomly switches inputs, turns on/off, won't turn off, remote stops working, on and on.
Summary: I purchased the TX-NR708 on Jan. 1st, 2011 and now less than 5 months later I'm sending it in to be serviced for a second time (at $30 each time for shipping). The first time was after just 6 weeks when the unit would not power on (just made a clicking sound when attempting to turn it on).
Summary: When I bought the 708 in February, 2011 I read all the reviews and was impressed with the features and price. The reviews at that time gave no hint of what was to come. Almost every review was positive. I installed the receiver and was very pleased with the sound and ease of setup.
Summary: Had this since Nov 2010 then remote started working intermittently a few months ago Then quit working altogether last weekend - for receiver only. Remote controls other devices just fine. Found numerous complaints on AVI user group - this is a chronic problem with a couple of Onkyo models.
Summary: Oh yes, it has all the cool features and setup tools. It is easy to setup and use (1 star). And it worked great for about a year and then the problems started. The remote will lock up and just quit working. The receiver will lock up; none of the controls on the front panel will work.
