Check the voltage and systematically troubleshoot each component to identify and eliminate the issues one by one.

After repairing the T15, it initially detects and tests 60 chips successfully. However, it subsequently starts producing garbled output. How can I effectively diagnose and identify the source of this problem?

Replace the power management IC [U1]

The S9's cross-domain voltage is only 0.28V and the 8.5V voltage is missing. Despite troubleshooting the PIC and MOS tubes, the issue persists. What could be the cause of this problem?

Please check the complete kernel log.

After repairing the S9K and successfully passing the fixture test, it still lacks computational power when running both with multiple boards and individual boards. What could be the underlying issue causing this problem?

S9K does not support board stacking. If the control board is not faulty, please export the complete kernel log and analyze it for further investigation.

What could be the reason for the S9K's chip model replacement resulting in a computational power of only 3.6T during machine testing?

1\ Test the diode value and voltage of the 3 transistors Q5,Q14,and Q15 comparing the working hashboard. 2\ Test the DC-DC circuit.Remove all components related to short circuits on the board. 3\ Connect Q5 Pin-G to D3 and inspect the boost section for any issues.

What could be the issue if Q5 on the S9K, when removed and tested, shows a reading of 0.8, while Q8 on the faulty board has an abnormal input?

1. Tighten the screws on the power supply copper busbar. 2. Replace the copper busbar with a new one. 3. Replace the screws. 4. Upgrade to the latest firmware.

What could be the problem if the Antminer S11, with a functioning board, consistently displays low voltage and subsequently shuts down?

IP address conflict. Connect the miner's network cable to the laptop and check if you can obtain an IP address and access the internet. Then,reconfigure the static IP address.

What could be the issue if the machine's Light is green, but it cannot be detected through its IP address, and accessing the backend is also not possible?

Check the miner status,there different frequency and no fan speed. 1st,eliminate the power supply as a possible cause. 2nd,try reprogramming the PIC of the hashboard with a frequency of 500. After reprogramming, the frequency should be 550. 3rd,do single-board test for the hashboard with 0 hashrate.

When the machine is running, does it consistently restart despite attempts to flash the firmware?

First check the fans. The fan error rate has increased, leading to a decrease in hashrate, and ultimately resulting in a network failure. If changing the fan can't solve the problem, check the network again. If it still doesn't work, the CPU of the control board may be faulty.

According to the provided image, why does the machine disappear from scanning after running for two days?

If the PSU and mosfet are OK,it may be caused by 1\ The voltage configuration in the CONFIG file has been set the too high. 2\ The abnormal voltage domains or ground issues 3\ The abnormal signals Is there full asic? Replace the U22 and the capacitors,resistors,mosfets around it.It is possible that they were not completely replaced, resulting in a failure when powering up.

What could be the issue if the S9K DC-DC output for headphones is too high at 10.8V, while it should be normal at 10.2V?

Check whether there is full chips from kernel log. If missing chips,do single-board test. If the chip's hashrate is low, replace it. Check the 3 hashboards temp sensor model,keep them the same.

On the S9i machine test, is there a significant number of chips but insufficient hashrate?
