Have you tried a factory reset on the amp?
Hold down the A (or clean) button as you turn on the power and hold the button for 5-8 seconds.

I have the same problem. I can hear something turn on, but it's not the usual 'thud'.
I checked the connections on the speakers and it all looks fine.
I have also tried the factory reset.
