Pp5v_s4rs3 820-3435
820-3435 MacBook AIr A1465 11" No 5V on DC-IN on pin 3 on J7000 (PP5V_S4RS3) (edit: that's probably not right, misread the schematic) Was already getting no voltage on pin 3 (J7000) before I fixed PPBUS_G3H, which was shorted to ground by a blown capacitor, on the PPBUS_S5_HS_COMPUTING_ISNS line.- Brennan

I have an 820-2936-B with no image / video, but works perfectly on an external monitor. History: customer replaced their own screen...- Brennan
