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...

the boards i have repaired light up when they are connected to the controller and start hashing. when a miner doesnt detect the board i look for the one without the red led on and thats the one that failed...in my case at least. i could be wrong but i think the light only comes on when the board is being checked for connection to the controller....when the chips are being checked and tuned....and finally it stays solid when the miner is actually mining away. hope this helps.
