    Lampu LED Samping (asesoris) nyala kan .... ?

    N3220 LED Problem Checking & Solution :

    1. Download dan Lihat Schematic & PCB Layout yg sy buat & upload
    2. Periksa LED LCD & Keypad > pastikan Menyala Normal dgn PSU
    3. Periksa input tegangan kerja yg dibutuhgkan Driver N2400 (Vbat = ~4V)
    4. Periksa tegangan "Enabler" dari UEM ke Driver saat keypad ditekan (2.8V)
    5. Jika semua hal tsb Ok, ganti IC Driver N2400 > test > ok > finish
    Jika input Vbat ke Driver tidak ada :
    Buat jumper ke titik Vbat lain: J2003, L2200, dll ato lsg ke kaki (+) konektor baterai

    Jika input tegangan "enabler" dari UEM ke Driver saat keypad ditekan tidak ada :
    periksa jalur ke UEM = baik > IC UEM Damage > Rehot/Reball/Replace
    periksa jalur ke UEM = putus > jumper

    Jika LED LCD ok, LED Keypad mati :
    Ganti Driver LED Keypad (V24240) > test > ok > finish
    atau ... buka Driver tsb, lalu jumper kaki katoda LED ke Ground (Nyala LED Keypad akan mengikuti LCD dan tidak akan dapat mengikuti Ritmik LED asesoris disamping ponsel)
