The DS1100 fell off my son's bedside table (which is 24" tall) last night and now there is no sound. The clock and light work fine. I tried his iPod and my iPhone 4S. No sound. Are there parts that I can get to fix the iPod interface if that is what is broken? Nothing appears to be broken on the unit, nor is there rattling when it is shaken, so I know there aren't any pieces floating around in there.

Is there anything I can do?
