2012 Apple MacBook Pro 820-3115 no green light no power short on PP3V42G3H

Today I was working on the older 2012 MacBook Pro 820-3115 logic board with major liquid damage without any power and no green light on the charger.

Found short on PP3V42G3H line. Replaced the U6990 power chip that caused the short. Ultrasonic the board and Mac powered up without any other issues. Another happy ending.

If you have any questions related to logic board repair please call 561-727-5735. We are located in the heart of West Palm Beach, close to CitiPlace, downtown.
