Antminer L7 hash board troubleshooting about the 23V boost circuit

Antminer L7 hash board troubleshooting about the 23V boost circuit In the last video, we talked about the 19V boost circuit of the L7 hash board. The topic of this video is about the 23V boost circuit. The circuit is mainly composed of boost chip, boost inductor, rectifier diode and filter capacitor. The 15V voltage input by the PSU will output 23V voltage fter passing through the boost circuit to cooperate with the work of the DC circuit. Similarly, if a voltage of about 23V is measured at the capacitor, it means that the circuit is normal.
