Mine did the same thing yesterday. For no reason it just wouldn't power on. If I turn it all the way up to like 10 I can here a scratchy sound like the speaker is blown. All my components and other speakers are fine. Suck I have only had it for a little over a year and the thing weighs a ton so there goes any chance of sending it in my repair. Let me know if you hear anything from Athena or any other fix. I am going to call Athena today.
