I have several faulty miners needing hashboard repairs. I have all the equipment, and a basic knowledge of electronics.
I can find many helpful links for repairing S9 hashboards. But not many for any newer models.
I suppose mainly I am looking for the expected resistances and voltages at the test pins for each chip, and how to diagnose which chip actually requires replacing.
Also, are the temperature sensors part of the chips, or are these separate components?
Thank you
