It's plugged into an outlet close to the back of the TV. Usually you can remove the kitchen drawers and get to it. I accidentally spilled some water on the kitchen counter and some of the water dripped down between the stove and counter and messed up the system. At first I thought a snake was loose down there but the speakers were making the racket. You should also be able to remove the TV from the outside by unscrewing 6 screws near the edge of the TV screen that will remove both the TV and bracket that holds it in place. Good luck. Oh yeah, when I put everything back together I added a cover over the top in case something was spilled again.
