What causes antminer control board failures? 3 of my s19 j pro 104’s stopped functioning one day a few weeks ago. The miners powered on but I couldn’t ping or locate IP and they were not hashing. I swapped the boards with new ones and they are back to normal. I have 8 immersion cooled s19’s that were running for almost a year straight before this issue occurred seemingly at random.
I also had a bad board in an L7 last year, same thing. Stopped connecting one day and a new board fixed the issue. Luckily that one was under warranty and swapped the board at the repair site after diagnostic.
Just wondering if anyone knows what causes board failures and how common it is? Can control boards be repaired?
The board I’m talking about is the one that the ethernet plugs into.
