had a issue last night with my antminer s2 i guess a hashing board died last night and kept turning off my antminer so there is an upside to antminer s2's is that there boards you can hotswap i found out
did some testing and one board poped off a cap or resister or something brown little box
looks like im looking for another board for my s2 ... took that board out and now my s2 is hashing a little less
I suggest contacting Bitmain and seeing if they have any to sale or might ask about repair (I don't know extent of damage if this is a option)-
https://bitmain.zendesk.com/hc/en-usYour other option is hardware buy/sell and see if anyone is selling. And if you do buy a new one you might list yours and post pictures depending on what poped off and how hard it is to solder someone might pay something or the board(again this would depend on extent of damage).
