I hadn't used the system in several days because I had moved the TV connected to it, preparing for my new TV. It arrived yesterday but now it seems my AVR is giving out. It will stop responding to any changes such as volume and input. I have to power it off with the hard power button to get it to reset. Usually it locks up again with in a few seconds. It appears to start doing it after it warms up. The audio may still continue to play unless the audio type changes (DTS, DD, Stereo). I'm not sure if it is the new speaker setup (it was working fine on Monday) or the new TV. I did connect the TV to the AVR using the Audio Return Channel input (my AVR doesn't support it), but I don't think that would matter.
I really don't want to have to spend the money for a new one right now. If I do, I hope I can find one that will work well enough (for the money) to get me by until I can buy a nice preamp/amp (looking at Emotiva) setup.
