  • [SOLVED]820-3437-A PP5V_s5, no power

    Hi.

    Corrosion to the board, previous work by customer, been through UC

    PPBUS = 8.62V
    PPBUS_S5_HS_OTHER_ISNS = 1.2V
    PP5V_S5 1.2V


    Oh, found the problem. I'll post this in case anyone else has a board like this.

    Someone had removed C7583 and torn the pad connecting to PPBUS_S5_HS_OTHER_ISNS...
    The connecting via comes from that pad through the very thin trace / pad of C7583. no idea if this is common but it may help someone if board has been fucked by customer.
