    Harap bantuan Para senior, awal masuk hp nyala tapi lampu lcd gak nyala, lcd udah coba ganti (udah test 5 lcd baru + 1 lcd copotan pinjaman teman) tapi blm ada perubahan sama sekali, kondisi hp masih segel, sy yg pertama bongkar, mesin masih mulus gak ada tanda2 kena air, dari usernya sendiri bilang hp lg di pakai tlp tiba2 gelap,

    cek tegangan kerja ic lampu nya di C419 dan C422
    cek Vout light di C419....jalur lampu dr ic power di R443 dan lcd back light kontrol nya di R427
    lihat gambar diatas......buka skema diagram nya
    moga berhasil
