    Bb gemini 8520 gak baca memory external... V2_85usd tidak keluar ( ANSWERED )

    SORI KALO REPOST

    MASIH DARI BB YANG SAYA POST DI SINI
    http://www.tiroid-flasher.net/f7/%5B...red-10313.html

    SETELAH KELAR DARI MASALAH CLOCK, ternyata bb gemini 8520 garepan saya tidak dapat membaca memory card,

    yang sudah dilakukan:
    1. cek jalur switch, grounding switch juga okay
    2. cek jalur jalur pin slot mmc ke Lilitan dan juga ke CAPASITOR, okay
    3. udah diintipin juga kondisi fisik slot MMC, okay
    3. D1118 dan D1117 diukur tidak ada yang putus jalurnya
    4. CEK V2_85USD baik yang di C1108 maupuin di C1027, ternyata tidak mengeluarkan voltase

    mohon pencerahan master sekalian, bisa gak diakalin dengan curi tegangan atau memang mesti ganti IC POWER/TPS??

    THX ALL

    OK thanks buat agan agan sekalian, curi tegangan udah saya coba, namun hasil tetap nihil...

    setelah curi tegangan:
    VDD udah muncul 2.85 volt
    SD_DAT0 s/d 3 muncul 2.65 volt
    akan tetapi SD_CLK tidak muncul tegangan

    V2_85USD keluar jika MMc sudah terdeteksi om.

    coba jumper swith yg belakang ke C1415

    Bilamana tdk ada teg di kaki 5 (CLK) maka Cek (West Bridge) maupun jalur yg short baik pd C1116/C117 maupun ESD D118.

    Capasitor maupun D1118 ini boleh dicabut tanpa dipasang lagi. Khawatir D1118 ini sdh short. Fungsinya hanya sebagai ESD pengaman.

    thx banget bos atas masukannya,
    pedoman pengecekan saya juga dengan gambar yang bos berikan
    saya cek V2_85USD sampai bb booting ke menu utama dengan posisi mmc dimasukkan, yang mana switch detect udah saya pastikan konek dengan ground, dan dipastikan juga switch detect memiliki voltase 1,8v ketika mmc dicabut...
    SD DATA juga tidak mengeluarkan voltase 2.85volt

    Setelah dicek capasitor C117 dan c1407 yang didekat WB serta D1118 dicabut dan dijumper, ternyata masih nihil,

    cuman mau nanya, persamaan IC WB buat 8520 apa yah?, soalnya ada bangkai BB 9300 ancur dan 9700 abis keinjak hingga padam, apa mungkin bisa dikanibalkan?
