Antminer S19j Pro hash board troubleshooting for 23V boost circuit

The Antminer S19j Pro 42601 hash board has a total of 2 boost circuits. In addition to the 20V boost circuit mentioned above, this video mainly explains its 23V boost circuit. The main function of this circuit is to work with the DC control circuit, which is mainly composed of diode, boost chip, boost inductor, and some capacitors. Similarly, to measure its output, we should measure whether there is 23V voltage across the capacitor C60.
