You can now try the charger and it should work just fine.

This is a common issue on this charger so unless you use a 5V charger, you may run into this issue multiple times on all models.

Do note that the white light will turn off after a few seconds unless a ring is placed on top of the wireless coil and therefore, the charger is charging the ring (the white light goes to flashing/breathing). So do not worry if the light turns off while you are testing it after the repair, it is the intended behaviour.
