I had the exact same problem when I received mine last week. Hooked everything up, threw on the master switch on the sub, and pushed the power button on the control panel. Nothing happened. Actually, I heard a very brief THUMP from the sub, but that's it. I was about to email a complaint that the system was DOA when I decided to unhook the control panel cable from the sub and reinsertit. Presto! Everything worked. I have no idea what happened, since I had checked the connection before (but never unhooked it). Maybe the system needed warming up the first time? Unlikely, I know, but I'm at a loss as to why it didn't work at first. Oh well, things work now
