    keypad ponsel ini di katrol 1 capasitor dan 9 resistor yang terhubung ke ic keypad
    cek R2591 - R2599 dan C2596
    cek jalur keypad nya hingga ke rap....dan re-hot rap nya
    cek jalur keypad ke konektor board to board nya x2520 dan bersihkan dari korosi
    jika masih belum berhasil...ganti ic keypad Z2550
    lihat panduan cara pengerjaan jumper keypad nya di bawah...moga berhasil
