Bitmain Warranty is not associated with Bitmain at all - its a separate company.
I am aware they do not repair and they have two places...
So Bitamins main purchasing site will eventuqlly lead mr to your site above ?
It is NO WHERE on Bitmains site.
I'm just a noob, but my e9 might have a bad board, and when I was looking for a replacement I saw s9 replacement boards for 125-150 usd on ebag. New, they say. If you have to pay that anyways - and ship your miners out - it might be cheaper and faster to buy that and replace yourself.
Good luck.
I do not think you can buy a working S9 board for $125-150. Its either a scam or in the fine print a non-working boards.
