EDIT: MacBook history. MacBook Wont boot past apple logo screen.. A1278/C17J9JQHDTY3

  1. MacBook randomly died and won’t start.
  2. I opened MacBook, evident water/liquid damage.
  3. alcohol soak, swab & dry.
  4. SMC reset.
  5. MagSafe charger orange/green light. What do I try next? How can I fault find the battery, dc-in board or logic board? Logic boards are stupid expensive… Literally 90% of the cost of the MacBook when it was new.. I would assume it’s possible to fix it at component level? Any advice appreciated. Thanks, T.
