The following faults are derived from the Avalon 1047 miner log. You can check the solution according to the following fault phenomena.
Fault 1: chip BIN code error
The log display of the number 31 chip is wrong. Therefore, it is recommended to replace the chip directly.
Failure 2: The temperature of the chip is abnormal, or the voltage is abnormal
The temperature of chips No. 17, 18, and 21-120 are wrong. The working voltage of No. 17, 20-104, and 106-120 chips are abnormal. You need to use the oscilloscope to check whether the chip's CK, C, R, and D signals are abnormal (you can start with the 16 chip), find a chip with an abnormal signal waveform, and replace it.
