Antminer S19 Pro hash board troubleshooting for temperature sensing circuit

The temperature sensing circuit of the S19 Pro hash board is composed of 4 temperature sensing chips, which are connected in series. The PIC chip will control the work of the temperature sensor chip through the 1 and 2 pin serial bus of the temperature sensor chip. When troubleshooting, it is necessary to pay attention to whether the resistors connected to the temperature sensor pin is abnormal.
