Blackberry 9900 Dacota (Blank Display)

Rabu, 11 Agustus 2004 H-Blackberry

punya kasus BB 9900 Dacota masuk servis dlm kondisi blank display (gelap)

kondisi lampu layar nyala, bisa backup data & reinstal OS sukses, bisa call kesimpulan, ada jalur LCD yg bermasalah

langkah yg dikerjakan

reinstal OS sampai sukses, hasilnya tetap sama
ganti LCD, hasil tetap sama
cek resistansi masing-masing jalur LCD, ada yg tidak beres dgn jalur 6 (CBABC_PWM) dan 7 (LCD_VSYNC) pada komponen D1710. Kedua kaki ini saling bersentuhan.
pisahkan kedua kaki ini (bad solder), maklum ex-repair
tes kembali nyalakan HH, maknyuss...
solved
