How much does it cost to repair/replace a backlight?

[bBney]

 The phone is fine but i cannot see the screen unless i place it at a cartain angle against a bright light.

I thin the phone is damaged by wateer, i got it in the toilet bown by accident and it became like this...waterproof?Afraid not.
