    Blackberry 9300 sinyal SOS


    BB 9300 sinyal SOS.

    pertama coba jumper kaki U206 ke R225
    SW201 jumper in-out nya
    ( lihat gambar diatas )
    jika masih seperti semula ...cek teg kerja U510 di C549 dan C550
    buka skema diagramnya ....moga berhasil

    ada baiknya bikin thread baru boss, sebab bb 9330 beda dengan bb 9300 ..

    sedikit membantu , cek jalur antennya ( buka skema) .. kalau OK dan masih nihil coba REHOT ic PA nya ..

    Sy ada kasus yg mirip.. BB9300 no signal 3g nya, tp 2g nya msh oke buat telpon & sms. Trus sy cek jalur Vbatt PA dll di sktrnya, msh oke. Tp pas dipegang, ternyata U510 nya panas banget :confused: lom sempat cek yg lain2nya, bb nya malah jd matot :frusty: klo dipasang batre cm kedip2 led merahnya aja. Dicolok ke pc jg gk kedetek.
    Mohon pencerahannya master2 :cry:

    sepertinya permasalahan ada di U501 boss ...

    coba angkat Ic U501 , cek jalurnya ... apakah ada yang SHORT? jika ada eksekusi dulu, pastikan jalur aman ..

    pasang kembali U501 .. lalu cek tegangan input di C502 harus ada minimal 3,3 V ( tegangan Vsys) dan tegangan outputnya di C203 danC204 . masing2 harus ada 2,8 V

    jika tegangan Inpput NOL cek R512 dan jalur ke Vsys nya, jika tegangan out put NOL coba ganti U501 nya, jika tidak ada partnya coba pinjem tegangan yang sama 2,8 V
