White circle lightning , doesn't charge, diagnostic steps

Testo:

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?

Dispositivo:

Samsung Galaxy S9
