I plugged the power cord into the back of the 970, then the other end into the wall socket, then pushed in the little power button on the back, but the amber stand-by light does not illuminate. Pushing the power/stand-by button on the front does nothing, pressing the power button on the RC does nothing, and pushing the various buttons on the front panels does nothing.

Is there a fuse or breaker somewhere? Have I missed something. And, yes, the AC wall outlet is live.
