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. I decided to move it to another room that has another TV that is not used too often but it will do the job. Here is where I failed, I bought another Onkyo.
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). This turned out to be a faulty 12 volt relay. Now, as many others have reported, the unit's IR receiver is no longer working.
Summary: There is a serious issue with many Onkyo A/V receivers built in 2010 including my TX-NR708. It's in the shop for the 2nd time. So far, Onkyo has failed to properly address this issue. The press release does say they will cover repairs even if the unit is out of warranty. *Unit does not respond to remote commands. *Unit does not respond to front panel input commands. *Unit cycles randomly and rapidly through input modes OR listening modes.
Summary: The NR-708 was a fairly robust receiver for this price range, and I was very satisfied with its performance, features and functionality overall...until it became unuseable after 4 months. At first it began switching inputs at random. But I was able to simply revert back to my original input choice. Then within a week it all the sudden became completely unresponsive to the remote or to any inputs on the front panel.
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. However, in early July, 2011 it began scrolling through all the sound options and was impossible to control, either with the remote or on the box itself.
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. Onkyo website FAQs indicated free repair including shipping, even if out of warranty. Called Onkyo and after long hold time, got hung up on.
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. You have to unplug it to turn it off. Even stranger, if you plug it back in but leave it off, it will come on by itself!
