Actually i'm facing the same problem with my ANTMINER S5+ when a board start giving me status -x then it disappear from the status area.
it started with one ASIC then the rest of it start doing the same thing until i loose one of the 9 boards from the miner.
i already have 90 days warranty from BITMAIN but until the moment i don't see any effective reply from them, so i turned off my miner and keep waiting for support here and BITMAIN support system.
i hope someone can help us with this.
Topic: S3 all ASIC's stopped working (Read 576 times)
Reposting here because BITMAIN deleted my support thread (nice, guys... real nice)
I have an S3 that was offline for about 4 months. I started it up a few days ago and it was running fine for a few days until last night it stopped running at full speed. All ASIC's except one were listed as x's. This is not usual and has happened before and is usually fixed with a power cycle so I powered it off. Then when I powered it back on, now it will not start any ASIC's at all. The web interface works, network is working, etc. In the web interface there is nothing listed under ASIC's (literally nothing, it's just blank).
Both the green and red status lights are flashing in unison about once per second.
I run all stock clocks/voltages etc, no modifications. I have tried a full reset but that did not fix it. Tried multiple power supplies and no change.
Update:
After some fiddling I found that one of the ASIC cards is not working (there are two of these boards in the S3). If I only connect the working one then that hashes at half speed to a full S3. If I connect the other one either by itself or with the other working board then it will not hash at all.
So it seems that one of the hash-boards is bad for some reason. Any ideas how to affect a repair? I'm not sure what would make the entire set of ASIC's go bad so I'm guessing it's a component on the board... Or are they like Christmas tree lights and if one ASIC goes bad, they all go bad? What is the PIC looking for when it talks to the hash-board?
Nothing looks burned or broken on the nonfunctional board. I'd like to repair it if possible.
Edit:
For those wondering. This was my original support post (now deleted? WTF): https://forum.bitmain.com/bbs/topics/1961
And the cache is here (at least for now, until bitmain requests a takedown... again, WTF... What's with these guys?)
