Try disconnecting everything else from the unit and also unplug it from AC power for 60 minutes. At this point simply plug the AC back into the unit and see if it turn on. Let me know what happens.
To reset the lockup on your Pioneer receiver, press and hold ENTER + VIDEO2 for 3 seconds and hopefully this will allow it to operate properly.
If this doesn't work, then it's very likely that the unit had a static charge or other issue when being moved, and is in need of service. I can send you the contact info for Pioneer's service center locator if you'd like.
Sorry about that. That was the only documented reset that Pioneer had, and it was for earlier models that would shut off and only display MCACC flashing on the display. There are no documented solutions for the problem you are having.
They will often experience this behavior if there is a short internally, and the unit is protecting itself. You'll need to send the unit to an Authorized Service Center for them to diagnose and fix the problem. I can send you the contact info for their Service Centers if you'd like.
