Here's our guide on repairing liquid dMAGE: http://www.ifixit.com/Wiki/Electronics_W...

Without replacement parts it's very hard to say what may or may not need to be replaced. If you have one of the newer machines with LSI (liquid submersion indicators) just follow the red dots to get an idea of what may be damaged.

I don't think that water hits the logicboard and fries it every single time. I have repaired iphones/toys with water damage just with repeated cleaning with isopropyl alcohol and a soft brush (girly eyemake-up brush) the parts that most needed replacing were connectors..the water tends to pool in the logicboard side. I know I'm answering about a macbook, but I think the principle is the same..clean your board,dry-assess residue,clean again, and again and again. Remove any white or greenish residue from around ALL the parts. Leave to dry. use a new/known good power source to restart...hopefully you'll then be able to troubleshoot. As Mayer says follow the trail..if the liquid came in through the keyboard then it probably ran off at the edges/through holes in the keyboard, check the areas under that. A good multimeter for testing parts helps.

It could be anything. After using ifixit to disassemble my whole mac one cable after another after my toddler dumped a full glass of water on the keyboard, it finally ended up needing a new battery and leaving the cable for the external battery indicator lights disconnected... that was what shorted! With it connected no recognition of battery even existing. Disconnected, the battery charges and operates perfectly. I'll live without the lights...
