.....Sabedra, forgive me, I was trolling a little with additional wordage....unplug the unit from the AC....seperate the compent pieces from each other including the speakers....although I don't understand why, if NOTHING is receiving any AC, in any way, and then again, capacitors hold....leave it alone for 24 hours....at that point any resets should surely have activated as implied by the manufacturer, to be initiated by a resurgence of AC....then, if you have disconnected the speakers, and I would since you're losing bass, carefully check the speakers are reconnected correctly possibly replacing iffy looking connectors or wire....and make sure you don't cross the wire if it's wire....go the full length with the wire pinched between your thumb and forefinger making sure the wire does not roll, and know for sure which side is +, and which side is -....Sabedra, it's just us here late, so reply if needed....Clint, see how I'm tryin' to help out?.....
