Check the kernel logs errors whihc related to the temperature problem. Verify if the temperature sensor model is correct.
If the temperature sensor model is incorrect, reconfigure the temperature sensor file to ensure it matches the correct model.
If the temperature sensor model is correct,replace the chip to resolve the issue.
If it passes the single-board test, update the firmware. And then check if the 3 hashboards temp sensor model are consistent. If single-board test fail, there is a temp sensor issue. prioritize replacing the chip on the 62nd board.
First, do not plug in the faulty board with the data cable. Test only the good boards individually to see if they function properly. Tighten the screws and secure the clasps with pliers for a firmer connection. Update the firmware and tighten the screws. Use the voltage adjustment line to supply power, monitor the chip status with the control board, and then adjust the power supply.
Do single board test to see the issue. If report 0,check the RI signal from the last chip. If report x asic, check the domain voltage where the chip located.
Firstly, balance the voltage domains. Alternatively, you can short-circuit the RI signal to provide a stable 1.8V and check if it reports correctly. If the voltage domains are not functioning properly, it is likely that the signals will also be affected and not function correctly.
There may be an issue with the 4th voltage domain counted from the end or that there is a missing VDD voltage domain, specifically the 15th voltage domain.
The heat sink connected to the 15th voltage domain and 1.8V LDO in 10th voltage domain is conducting.
If not conduct,jump to LDO pin 1,pin 3.
