I think that with such a voltage, something should be warming up, first it is necessary to remove the jumper or inductor of the 5 volt line and replace the voltage, then if the resistance is low, apply voltage with a limit to the current of 0.5 A and 2-3 volts and check that it is heating |

Be sure to check the USB, maybe the USB jack has crumbled. |
