Samsung SM-G316 (Touchscreen Tidak Berfungsi)

Kerusakan:
- Touchscreen tidak berfungsi.

Analisa:
- Sudah gonta-ganti touchscreen tetap sama.
- Ukur VTSP_1.8V ok.
- Ukur VTSP_3V tidak keluar tegangan sama sekali.
- Ukur hambatan jalur VTSP_3V ternyata short full.
- Injek tegangan di fuse jalur VTSP_3V sambil tuang tinner, keluar asap.
- Karena bersebelahan dengan capasitor VTSP_3V, saya coba cungkil capasitornya, ternyata masih short.
- Coba injek tegangan sekali lagi di fuse VTSP_3V, sambil raba area yang panas, terdetek di salah satu capasitor kecil dekat IC Power.
- Cungkil capasitor kecil tersebut.
- Ukur kembali hambatan jalur VTS_3V, sudah tidak short lagi.
- Coba tes touchscreen, normal.



Proses analisa short pada jalur VTSP_3V



Capasitor kecil sebagai tersangkanya



HH normal kembali
