    Hello. Did you Fix your problem ?

    I had same problem with one of my Antminer S9 sometimes 1 Board was getting 00000 Hashrate sometimes 2 boards stopped. First I thought it was power unit changed it but after a while same problem then while trying to fix miners i touched Metal Frame(Rig where miners stand) and a PSU and felt small electric current going threw me after what all miners that was standing on that metal rig wend 00000 hash rate.


    I Put all miners and power supply on a small plastic corrners covers with 2mm height so they do not touch metal nor miners Nor Power Supply. Since then I never had any problem like that Hope this helps with this kind of problems Good luck 🙂

    hello when you send for repair, you mean send them to china? or do bitmain has a center in the US where they repair the hashing board, plus how long are they under warranty?

      180 days warranty, after that each repair is about $50-$100.

      Bitmain just added a repair facility in California, and it works ok so far.
