A1465 Macbook Air repaired after heavy liquid damage.

Once power was restored to this Macbook by replacing 2 resistors on PPBUS_G3H which is the power rail responsible for all others, though it would charge the battery, it would not run from it.

We replaced the Mosfets and battery power was restored. Next the back light circuit which is needed to power the screen’s brightness so that the image may be seen.

😁

On removing the back light driver IC the 50 volt pad was toast, so we had to run a new trace and lay a new pad to restore the 50 volts.All done and held in place & insulated where exposed by the green conformal coating.

Macbook back up and running at a fraction of the cost of Apple who deemed this unfixable.
