My dad dropped it in a bowl of water a while back and took it out immediatley and left it to dry. After a few days it still didn't work so he sent it in but they sent it back saying they didn't cover waterlogs. Its a few months later and I want to use it but it won't turn on and i've tried plugging the charger in.It worked once when we got it back and won't again. Any suggestions to make it work?
