Water Damage, Logic Board appears fine...no Boot?
June 2014 Manufacture date
S/N can be seen in the picture.
Daughter spilled Vinegar+water solution on keyboard. She may or may not have properly powered it off immediately.
-Power button causes no response, no boot
-Attaching the charger cable gives me the 'AHHH' and the fan and HDD spool up; no screen ----Originally the HDD would not spool up, and I replaced it with a new one (sans OS). So the original HDD is confirmed bad. But still have the same root issue with a new one.
Done so far:
-Disassemble and clean logic board with isopropal+toothbrush under a nice microscope.
-Inspected each component for signs of shorting & found none; There was some light corrosion, but not significant (I think based on low experience). In viewing the picture of the logic board, I saw a bit more corrosion at the battery connector that I have since cleaned up. Did not include a pic of the back side of the board because it looks pristine.
-Tried the RAM switch/re-try with 1 chip at a time.
I have good technical capability, but know very little about Macs. I'd appreciate it if anyone could advise the proper next steps to debugging this. My plan for tomorrow otherwise:
-Have not removed the keyboard yet, but it looks like power button is a part of that component. Also looks like 100 screws holding the keyboard lead frame must be removed to replace it...don't see any visual indications of problems.
-Soak logic board in water to ensure cleanliness
Is this a good question?
