What help are you looking to get? A bad board is a bad board. If you have gone though the basic troubleshooting and its still not working the only option you have is a paid repair service.
I wanted to know if it was a bad board... So what do you suggest me man? I do not know where to send it... Somebody told me about bitmainwarranty but I'm trying to contact them and I do not receive any anwer... Is there any website where I could buy that board or a place where I could send it?
Thank you so much for your answer Fanatic26
