I don't think it's the switch. I had this happen to and I posted the questions here. When I took it apart, I found they the drop had caused a connector to pop loose. I think it was the one marked #5. It's a super tiny connector. I plugged it back in and everything worked. Might be worth looking at. The instructions are on here, just follow the instructions for taking it apart and look for the #5 connector to be loose. Go to the "Repair" section of this site and find the repair for the mute switch and follow those to take it apart. Look for that small plug and make sure it's plugged in.
