Default [Q] Issue with loud speaker

Hey all. Long time reader, first time poster. My girlfriend recently left her phone on a table near a glass of ice water. Over time the condensation leaked onto the table and under the phone. The loud speaker was all that was affected. Once she noticed it was making an odd sound I yanked the battery and let it dry out. Needless to say for the past month the speaker has not worked. Everything else about the phone is fine. I ordered a replacement loud speaker and put it in the phone today expecting the problem to be resolved but no luck. I was wondering if anyone has any hardware expertise with these phones on what else to try. I'm assuming something else (not replaceable) has shorted out but figured I'd ask before calling this a lost cause. Thanks in advance.
