    met malam,,dapet 9000 mati diukur PS via vbat arus 0,42A atau 420mA via vbus 0,02A lalu turun ke 0,00A
    buka kaleng power ukur impedansi syarat kerja tidak ada yg short lgs hajar ic power ganti baru lalu tes kembali arus ampere sama seperti awal cabut SMPS tetep begitu juga.
    suntik kasih V ke vsys ampere 0,42A dan vpwr_sys jg sama ampere 0,42A
    buka skema search vpwr_sys ada banyak mampirnya di regulator2 kaleng yg berbeda2
    bagaimana ini apa mesti cabut2in satu2 regulator2 berlambang U

    mohon pencerahannya,,,terimakasih
