Short beres, trackpad tidak berfungsi, software sudah, trackpad sdh diganti, hasil nihil, membuang 5 buah dioda yg dengan segala ketrbatasan analisa saya dioada tsb tidak bekerja dg baik. pada Pcb berbeda kutub negatifnya dg yg ada pada skema, gmbr yg saya lingkari berwarna hijau mirip resistor, mohon bantuan dan petunjuk para agan atas apalagi yg harus saya lakukan ? Terima kasih.

    kl dioda dibuang tidak bermasalah koq,dioda itu hanya sebagai pengaman saat ada tegangan statis

    tidak bekerja yang bagaimana ?

    macet total .. atau bisa geser , atau KLIK nya saja yang berfungsi .. atau sebaliknya ..

    yang perlu diperhatikan

    - cek resistansi jalur TP .. (buka skema)

    - cek dan ukur tegangan kerja TP nya

    coba ganti konektor trackpad nya dl aja

    kl setelah ganti trackpad masih tidak mau,maka langkah selanjutnya adalah fokus pada gambar dibawah ini (yang saya berikan garis dan kotak berwarna merah)

    jangan lupa ... celk jalur SCLK dan SDA nya .. jalur itu terhubung ke kamera ... kadang dengan melepas kamera TP bisa berfungsi ..


    kerjakan pelan2 dan cermati tiap jalur dan resistansinya ..

    ikuti arah2an yang sudah dipaparkan rekan2 diatas
