First, perform a visual inspection to ensure an adequate power supply. If the power supply is insufficient, check the resistors near U1 to verify if they are functioning properly. Use a known good board as a reference for comparison. If the hashrate is still insufficient, replace the first chip. Additionally, during the voltage detection process, measure the 5 signals to see if there is any activity. By identifying the chip with abnormal signals among the 63 chips, the issue can be resolved.

Without detecting any voltage, in the end, even with chips number, there is insufficient hashrate. As shown in the image, how should this issue be addressed?

First, resolve the issue with the RI return signal. Ensure that the RI signal is properly connected and functioning correctly. Additionally, measure the signals in the voltage domains to assess their integrity.

For the T17 miner, there is an imbalance in the domain voltage, with a report of 0. Some positions have a low RI return signal, while position 6 has no RI return signal. How can this issue be resolved?

Check the ground resistance of LDO is normal or abnormal. If it is abnormal, consider replacing the LDO. If it is normal, test the input voltage of pin 5 to determine if it is sufficient for voltage conversion.

What should be done if the 1.8V and 0.8V voltages are abnormal?

Check if the fixture is functioning properly or if a reboot is required. Verify the reliability and integrity of the fixture. Investigate any potential issues with the data cable interface. Abnormal resistances at the interface are often the cause. By performing these checks, you can identify and address any issues related to the fixture or data cable interface that may be causing the abnormal RST reset voltage.

The report shows a value of 0, while the RI voltage is normal. The reset voltage for the first chip (RST) is 0, while the other voltages are normal. What could be the possible explanation for this anomaly?

In this case, you should short-circuit the CO signal of the chip and continue the process. If short the output CO signal of chip 1 ,reports asic 1, continue with the rest of the chips. Identify the defective chip that cannot receive the signal and replace it.

The voltage and resistance measurements appear normal, but the fixture still displays 61.

See the kernel log. Temperature can not go up. Update the new firmware.

What could be the reason for the new S17+ machine failing to start up?

Usually the hashboards have problem. Do single-board test.

Which aspects should be checked when the T17 miner experiences dropped boards?

Replace the power management IC and check all the LDOs.

What does it mean when the L3+ miner displays this error code and continuously cycles through it?

Machines that were previously running fine but cannot run after board stacking may not be related to frequency but rather to the BIN (firmware version) used. Try using similar BIN versions, such as BIN4, and check if the A5V1R (ASIC version) is the same.

Do we need to recalibrate the frequency for the T15 multi-board miner that is unable to start up?

The PSU is abnormal. Replace and test again.

How to deal with a non-rotating power supply fan on the T17? After running for a few minutes, the back-end logs indicate a temperature control chip failure. Do I need to replace the power supply fan?

Error_ASIC_LOSS,do the single board test to find out the defective chips.

What could be the problem with this T17+ miner?

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?
