The model number is NWZS545, it got wet but that was a couple days ago and it was working just a couple of hours ago. I reset it multiple times, I updated it, downloaded any available drivers on the sony site. It's charging fine, and it's fully charged, it just won't turn on. The only other thing I found that I could try was unscrewing and re-screwing the screw on the back, which I'll do when I find a small enough screwdriver. Is there anything else I can do?
