Can I get my water damaged gopro repaired?

So, i had my gopro on my helmet with the skeleton backdoor on and accidentally bumped it into the water. It was only there for about 3 seconds, but all i did was dry it off with my shirt. The next day i researched how to fix, and i tried putting it into rice for a week, but still nothing. wont turn on. Can i still repair it or is it cheaper to get a new one?
