I plugged in the power cord into a 220 socket, forgetting it had to be 110, it wasn't connected to the wii at the time, and I heard a little pop. Now the Wii won't turn on. I tried connecting it to the Wii later and pressing the power button and nothing happened. Did I just mess up the power cord, or could something have happened to the Wii itself when I connected it and pressed the power button?
