Macbook pro No boot

So a cooler fell over on my 2012 mac-book pro and leaked water on it and some got inside. I disassembled the machine and there was a small amount of corrosion on the logic board i cleaned the corrosion spots with 91% alcohol and wiped up all visible water i then let the machine dry out for a day or so. I then booted and it actually worked!! However the next day when i went to boot the machine i got nothing no sound or anything. I now have the computer disassembled again. So my question is how can i fix this if at all possible, i really dont have another 12 hundred bucks to blow on another MBP. any help is greatly appreciated Thank You!
