    sy sdh coba ukur pd titik pin outnya BB 9300 titik ukur ic power.
    yg tanda biru tegangan tdk keluar
    yg tanda kuning tegangan keluar menunjukan volt normal yg seperti gambar
    yg tdk ada tandanya tegangan keluar tp tdk menunjukan volt yg smestinya pd gambar.
    sdh coba ganti ic ORIGINAL nihil
    Mohon Pencerahannya..?
