i repair ipods and stuff for some extra cash on the side and whenever i get a water damaged thing i put it in a vacuum chamber i have and leave it there for a few hours for the water to evaporate, just make sure you open it up first, at least take the screen so the water has somewhere to go..., usual this fixes it but if not you can try and figure out what part there is still a problem with, science departments at schools usualy have these idk where else you could get one
