All the chips have been tested, but temperature 0 and all chips' hashrate reported as [00].

See the below single-board test result. There are 8.4V,8.5V domain voltage, replacing chip 1 did not work.

No hashrate, replaced several PSU, but did not solve it.

In the case of the S9K miner, why is there a decrease in computational power for hashboards 41-50 after the 40th hashboard?

If the chips are confirmed to be in good condition but there is no computational power, how can we determine if the machine itself is functioning properly?

How can we accurately identify which chip is faulty when the LDO resistance is abnormal and not functioning properly?

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?

Several boards have been tested, and all of them show a temperature sensor reading of 0. Even after replacing the three temperature sensor files, the issue persists. What could be the problem causing this issue?

How is the temperature of the hashboard uploaded? When encountering a signal interruption where the temperature is not displayed, how should the issue be investigated and resolved?

The total hashrate is consistently insufficient, and there is no temperature reading. The individual board tests show no issues, but the third board continues to lack computational power.

The last five voltage domains have voltage, while the other domains do not. The 8.5V is present, but the LDOs have no voltage. What could be the problem causing this issue?

What could be the issue if the hashboard does not have an 8.5V voltage supply?
