iPhone 5S apparently dead
my iPhone 5s’ screen was damaged.
I changed it, together with the backside plastic parts at the top and bottom.
Since then it won’t turn back on. It is even not detected by iTunes.
I have made the following measurements with battery connected and USB port connected to power outlet:
- PP_BATT_VCC: 0V
- measured between TP2 and a screwhole
- PP5V0_USB_CONN: 0V
- measured between TP1 and a screwhole
I haven’t found any test point for PP_VCC_MAIN.
Would anyone have a clue as to where the problem lies, and how to move forward?
Questa è una buona domanda?
