Antminer S19j Pro hash board training about the the LDO chips and signals voltage

When troubleshooting the Antminer S19j Pro 42601 hashboard, it is very important to measure the voltage correctly. This video will focus on explaining the LDO voltage, domain voltage, and voltage of the 5 signals on the hash board. In addition, we also need to pay attention to whether the voltages of the level conversion chips U4, U2 and U1 are normal. Only when these voltages are normal can the hash board operate normally.
