    dari analisa selftest....sinyal ponsel tidak mendapat tegangan : Rx _pll dan tx_pll
    cek N7451 dan N7590 kedua regulator mungkin tidak bekerja karena tidak supply tegangan dari avilma
    periksa VR5 nya yang digunakan rf clock 26 mhz karena ini komponen aktif
    sebelum mengerjakan yang diatas lebih dulu re-hot avilma...karena avilma berintraksi langsung dgn ic rf

    sekedahr tambahan dr pak de berkat,ada baik nya di cek dulu koneksi antara pad antena sama konektor nya.bisa jadi ada masalah bad koneksi aja.pengalaman saya tulang 3120c mudah retak/kagak kuat,so cb di cek2 dulu sebelum melakukan perbaikan yg lebih lagi...itu aja dah semoga membantu...
