Antminer s19 pro shows in the kernel log that the hash board reports 0 ASIC chip, and the miner has a fault that stops the hash operation. This article aims to analyze the S19 pro failure phenomenon and cause, and find a solution.
I. Failure phenomenon
The kernel log reports "Chain[0]: find 0 asic", which means that Chain[0] hash board did not detect any ASIC chip. The hash boards of Chain[1] and Chain[2] found the complete 114 ASIC chips. We need to troubleshoot the Chain[0] hash board.
II. Recommended solutions for reporting 0 faults
1. First, check if there is an issue with the hash board cable. We can locate the corresponding hash board through the control board cable interface. The log shows that CH0 only detected 0 ASIC chips. The hash boards corresponding to CH1 and CH2 are functioning properly. We can swap the cables of Chain 0 and Chain 1 for testing. (Note: Only swap the cable interface on the hash board side. Please refer to the image below.) Then power on the miner and check the log.
Situation 1: After swapping the cables, if the log still shows that Chain 0's hash board reports 0, while Chain 1 shows normal, check if the cable connected to the CH0 interface is loose or if there is a fault with the cable. If the cable is damaged, replace it, power on the miner, and observe if it can operate normally.
Situation 2: After replacing the cables, if the log shows that Chain 1 detected 0 hash chips and Chain 0 is normal, it can be determined that there is a high probability of a fault with Chain 1's hash board. It is recommended to troubleshoot the hash board issue using the following methods.
2. It is recommended to use the PicoBT Multifunctional Hash Board Tester to test the hash board:
a. Connect the 18 pin data cable on the test fixture to the Antminer hash board data interface.
b. Insert one end of the 12V power adapter into the 4 pin interface on the test fixture and connect the other end to a power outlet.
c. Set the output voltage of the adjustable PSU to 15V and the current to 31A. Then, attach the red and black alligator clips of the PSU to the positive and negative terminals of the hash board to power it.
d. After entering the test fixture page, we will see three types of hash boards: Antminer, Whatsminer, and Innosilicon. Use the buttons on the tester to select Antminer S19 Pro. Then press the white button to enter the test interface.
e. According to the screen options, click on PIC mode and select the number of tests. After adjusting the test options, press the white button to start the test.

In addition to the PicoBT multi-function hash board tester, we can also use the Antminer universal chip test fixture to test it. After troubleshooting the hash board problem, repair it.
