    Master..
    Mohon bantuannya, bb 9780 klo 3G & 2G on, langsung restart.
    Klo cuma 2G yg on, normal aja.
    Di software ulang, pakai rapido jg,masih restart.
    Di cek pake ps, led nyala arus naik sekitar 0,1mA.
    Led mati, turun jd sekitar 0,03mA.
    Di cek & di raba, gk ada komponen yg panas.
    Udh dicoba angkat PA nya, masih restart.

    IC 3G nya adalah : U404 (FEM/PA) dan FL401 (RF BUFFER).

    - tiadakan tegangan ke u404, dengan cara : cabut L407. Klo jadi normal (tapi gak bisa 3G), berarti FEM U404 rusak.
