Hi everyone,
I’m currently having an issue with my MacBook Pro (A1707). It doesn’t power on or make any sounds.
  • The charger is a generic third-party unit that had a loose connection at the AC input (127VAC). I fixed it, and now it delivers 20VDC to the laptop.
  • When connected, the fans spin for about 30 seconds before shutting off.
  • No display, no audio, and no signs of life during this time.

Any ideas? Could this be a logic board issue, or is the charger still a problem? Thanks in advance!...
