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?

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

As shown in the picture below, T15 machine, 58, 59, 60 are all replaced, it still doesn’t work, what’s the problem.

The control board or hashboard is broken, or the eeprom data is deleted. Program the eeprom data with code editor and then do the single-board test with the fixture.

The tester is normal, but machine is not working, and the log shows that the count is wrong. How to solve it?
