15 macbook pro keyboard not lit completely

The other night I was working on my macbook pro and I spilled some wine on the keyboard now only parts of my keyboard light.
Can I fix this or do I have to take it into my apple store for repair?

Well, the keyboard assembly needs to be replaced - so if you're comfortable tearing the entire machine down (assuming it's a Unibody MacBook Pro), then yeah, you can probably do it yourself.

Otherwise, you're looking at an AASP or Apple Store repair. I'd recommend getting a second opinion after you get the Apple Store quote as they tend to be on the high side.
