Question : on a working Hashboard, when powering it up with only 12v rails and not conected to a controller, is the red Tf led supposed to stay solid red?
Ca someone who poseses god miners and defect boards test this?
This ,I guess, would be a quick and easy method to see wich board is defect on your machine when one board is going defect...
(And give me a hint when a repair was succeful or not)
A solid red Tf led could indicate wheter clock and data lines are broken between the first and last chip on the chain and could prevent people from seeing "magic smoke" when trying to test boards...
