I recently had a liquid incident with my macbook pro. The keys were a bit sticky, but other than that everything worked as normal. Apple care wouldn't cover cleaning the keys, so I decided to do it myself. Now, after cleaning, the spacebar will not work (all other keys & power button work like new). The spacebar hangs when the computer is first turned on, and otherwise will not respond. It works fine with an external keyboard and with the on screen keyboard.
Can anyone recommend what I should do? Logic board replacement (please no!), keyboard replacement, top case replacement?
If it is a keyboard replacement, I feel confident that I could get the components taken apart, but not so sure I could get them back together in working order (with the cables might be glued/mic wires/bluetooth, etc.) - Any resources you would recommend?
