LED screen won't turn. Can I fix it?

After snorkeling today, I went to show my pics to my aunty when the screen died. Since then, it refuses to come on, and after review them memory card, I know it still takes pictures. I hate to throw it away and buy a new one, so is this fixable? If so, how much do you estimate it would cost to do so?
