devenmorgan, sorry but there is not a standard list of parts that will fail due to water damage. The number one thing to do is to stop using the device, (remove the battery) and to totally disassemble it. Use these guides for that. Then clean it with +90% isopropyl alcohol. This will displace the water and stop corrosion. It it okay to submerge a board in isopropyl alcohol. Check this guide to show you how to do it. Do not forget to clean the connectors on the board as well as the cables. Check your board for any missing or damaged component. After that, air dry all the components. Then re-assemble with a new battery This is not optional but a must, to avoid failure later on. " Water damage is the toughest to trouble shoot and to repair. Sometimes you can diagnose it by the symptoms, most often not. Hope this helps, good luck.
