Q: iPod screen went Black, turns on occasionally but remains black. Still can play music. Any Ideas on how to fix?

Yesterday I worked out with my iPod and a little sweat got on it but i quickly wiped it off. Then I come home and try to turn it on the following morning, and it just remains black, the iPod itself is working because iTunes is recognizing it but, the screen is black. Ocassionally the screen would flash showing that it is connected, what must I do? But this flashing isn't consistent.
