I have an Antminer S9 that had a chain that stopped working.  The web UI was only showing 2 chains working.  I restarted it a couple of times with no success.  I went to https://shop.bitmain.com/support.htm?pid=00720161126080548570Q2tDBXAH065D and downloaded a firmware update to try and even tried the Antminer Fix .tar file first.  My web UI went not showing any data of any sort in it.  I tried the reset of the Antminer, but that isn't doing anything.  Now I can't find it on the network.  It runs, but it doesn't seem to be hooked into the network at all and I have it hardwired to the router.

Any help please?  Is there anywhere that I can get replacement cards if one of the cards is bad?  Is there anyone in the US that does repair of Antminers?


Thanks!

Hi All,

I have plenty of dead S9 550 MHz hash boards and I'm looking to have them fixed.
I tried contacting bitmain warranty but they are not responding for last 15 days. The boards are located in EU.
Or maybe I can find some reliable tutorial how to diagnose and repair dead hash boards.
