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?

First review the kernel log and then find out the error, solve it.

Where should I check for the logs of the S17Pro?

To check the kernel log and do single-board test to find out the error and then solve it.

Is there a lack of hashrate when running the entire system，How to solve the issue？

Keep power on the hashboard,test the voltage of RI,BO,RST,CO,CLK to find out the abnormal chip and repalce it. Or the temp sensor error. Configrate the right temp sensor file.

The test shows garbled characters, how to solve it?

Confirm if the 0.9V voltage is normal. If not, measure the VDD-to-ground of the chip. If possible, remove the chip and perform measurements.

When a single chip reads less than 458 instead of the expected 912, even after replacing it with 4-5 different chips, what could be the source of this problem?
