    Diliat dr schematic, semua titik/pin diboard bisa dijumper
    Pin brp aja yg hilang?
    A1.. jumper ke L301
    A2.. jumper ke C307
    C1.. grounding
    C2.. jumper ke R306
    Semua komponen tujuan jumper dekat U305
    Kecuali B1.. agak jauh, bisa dijumper ke R914 dekat Zokus

    Diliat dari fotonya, tdk ada pin yg hilang di area U305, bro!
    Mgk yg dimaksudkan korosi n pin hilang itu yg di part U305.?
    Jika iya... tinggal diganti aja. U305 tdk bisa dibypass
