Water Damaged in my microsoft zune 30

Jesse, you will have to disassemble your Zune. Use this guide to remove teh logic board. Clean all the parts with 90+% isopropyl alcohol and a soft brush. You can submerge the board in the alcohol and do not forget to clean all connectors as well. Once you have properly cleaned it, check for any missing or burned looking components, then replace the battery and reassembly your Zune to re-evaluate. Water damage is the hardest to diagnose and to repair. Hope this helps, good luck.
