Solusi Ponsel Lokal Mati Total

Ponsel China atau hp lokal sedang marak.
Panik serta bingung bila terjadi kerusakan mati total, bisa jadi yang rusak adalah software atau malah hardwarenya.


Perbaikan Software:
Coba Anda format dengan melakukan flash terlebih dahulu, tapi backup dulu data yang penting.

Perbaikan software:
  • Gunakan teori DC Power Supply.
  • Bila tegangan tidak ada, pastikan konektor Rx dan Tx terhubung benar dengan kabel.
  • Kalau PIN Oke, coba cek jalur yang mengarah ke CPU melalui resistor dan kapasitor.
  • Lakukan pengecekan pada dioda jalur yang mengarah ke cpu.
  • Kalau pada saat flashing tiba-tiba berhenti, cek bagian IC Flash dan IC memori, biasanya IC tersebut menjadi satu IC saja.Ganti bila rusak.

Di Flash OK tapi ponsel tidak mau hidup, biasanya terjadi kerusakan pada:
  • IC Flash chip.
  • Clock crystal dan Battery 26 mhz, posisinya dekat IC RF.
  • IC RF.
  • IC Power.
  • IC Bluetooth.
  • IC CPU.

TIps tersebut diperuntukkan untuk tukang servis middle ke atas.
