    dapat kasus sama, kebetulan habis jatuh dan di service tempat lain.

    sudah di ganti fl1101 hasilnya tetap tidak bisa, mau ukur vsim belum tau metodenya. apa harus pakai battery?
    pakai PSU gak bisa ya?

    sisipkan simcard ,

    sambung jalur Vsim ke luar dengan kabel

    pasang batray

    lalu cek output tegangan Vsimnya

    sumber tegangan Vsim dari C1028 ...

    pastikan fL1101 nya bagus

    cek R1123 yang terhubung ke SIM_DATA

    pastikan kapasitor dijalur Vsim tidak ada yang drop, caranya coba suntik tegangan variabel dari 1V - 2,9 V ..

    lihat oergerakan ampernya, jika melonjak tinggi dpastikan jalur bermasalah, atau kapasitor ada yang drop

    benar skali kata Om wawan.. check teg v_usim di jalur C1028...

    kasus sim hp gemini short pada bagian V_sim dan coba lakukan pengukuran pada c1107 klo udah di lepas masih short maka lakukan pergantian ic power ( U901 )

    atau coba cabut C1329 tersebut brgkali nge ground..
