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

Can you post a picture of this white circle you're talking about? And where did you buy the battery from?

Could be a few things wrong with the device but i would test all major battery/power areas first have you tried to wirelessly charge the device to see it was battery or maybe even charge port?

I have no wireless charger, the second battery was charged when it arrived.
I am going to buy "hot air station" and remove the shield. Have no idea yet what and how to measure.
