    1. coba flashing ponsel nya....up log nya biar teman yang lain bisa bantu analisa nya...?


    5233 lcd problem_resize.

    2. analisa saya dari sisi hardware..?

    coba lihat gambar diatas...???
    bersihkan konektor lcd x2470 dari korosi dan debu
    cek teg kerja lcd di C2471 ( Vaux_lcd = 2.8 v ) dan C2472 ( Vio_lcd = 1.8 v )
    jalur lcd = konektor lcd ke emif lcd Z2450 dan N2460 ic lcd
    cek teg kerja N2460 di C2460 dan C2463 ... N2460 kontroller lcd ini mendapat tegangan puls dari dari ic power

    ( ponsel normal kalo pake usb ...maksud anda apabila di colokin charger ponsel nya hidup normal )..jika teg
    kerja N2460 baik .....coba ganti N2300 ic power betty

    buka skema diagram nya...moga berhasil
