    Agar tahvo mengeluarkan Vcore maka salah satu syarat kerja nya adalah smpsclock =2.4v selain rstx
    saat smpsclock 2,4v tahvo mengeluarkan Vcore 1,4v
    saat smpsclock low ..maka tahvo mengeluarkan Vcore 1,05v
    coba ukur smpsclocknya pake freqkwensi counter di kaki testpoint smpsclock..jika tidak keluar (pemberinya rap )
    adalah masalah...????
    smpsclock tidak keluar ke tahvo...bisa mengakibatkan hp matot..>>sedangkan jika tidak keluar ke ape smps bisa
    mengakibatkan LCD blank putih

    bos ennoz....coba analisa tahvo nya ...bila perlu ganti...?? ( batere ga penuh atau tidak nyimpan dan hp mau hi-
    dup kalau di colokin charger ) sehingga kekuatan batere ga bisa menstart up ponsel....??????

    kalau yakin teg Vcore drop, coba cek dulu C2302 & C2243, cek Coil/ganti L2302......
    bagaimana teg VcoreA nya normal gak ? kalau normal jumper ke vcore, cabut dulu L2302, bila hp mau nyala normal berarti Tahvo minta ganti....
