Hello,
I am trying to save a S9, my company doesen’t need it (no warranty).[br]
If I plug the phone I get a white circle with lightning icon, nothing change after an hour.[br]
Bought another battery, nothing changed.[br]
The phone turns on by itself, if not plugged. Phone vibrates, Samsung Galaxy logo appears and nothing happens.[br]
No signs of burned, missing or water damaged components. [br]
[br]
[br]
I have laboratory power Supply, microscope, multi meter and experience with notebook repair.[br]
Can you suggest me any diagnostic steps?
