Hello,

I have a Antminer from November(?) 2017 and it has given me some headaches.

The day the warranty was over one of the boards died. First it started showing the "x" on that board until it just disappeared entirely. I changed the cables connecting the hasboards to the controller board to make sure which was wrong and I've been mining only with 2 boards.

Now a new issue came up. All chains disappeared:


I've dissasembled it many times, changed the cables and the sockets on the controller board. Tried a couple different pools, nice hash, prohashing.... In every one it connects, the pools says the miner there but with no hash power.

Did the remaining dashboards just died?
Anyone has a solution for this?
Do you think one of those alternative OS can put this working?

Thank you
