I spilled red wine on my 13" retina MBP (I believe it's mid 2014 model). Computer froze and I powered it off, then tried to power on later (I know I shouldn't have tried to power it on). My husband did a complete dissassembly to clean and dry it out by taking out the logic board. There was surprisingly little wine on the inside. A few spots on the edge of the logic board and maybe one spot on the PCI-e flash memory (on the hidden side). He reassembled the computer this morning. It powers on (he gets the chime), backlight works, and the fan spins. Heat sink is warm to touch. Power cord indicates charging. But it doesn't boot. So my questions are: What else is there to try before writing it off as a loss? How do we know if the problem is with the logic board or with the PCI-e flash (or both, or something else)? Can we salvage the PCI-e flash or other parts? I.e. can we find an external case and connect it to our other computers using USB?
