I had pretty much the same issue, mine was running prior for a few days prior to the issue. I ended up unplugging everything and blowing canned air through the unit and reset all of the wires. It started right up, but out of my 6 S1s, it's the only one that seems to hash like crap. I'm assuming bad board or something.

If it haven't been touched, you can still try to contact bitmaintech for an exchange.
As for finding where it could come from, I'd suggest checking the voltage between any ground and the output of the 4 big square coils.
You should read something like 1.1v
There is also the U35 chip that gives 3.3v at the output of the small coil named "L5" next to the ribbon cables.
I'm not familiar with the S1 yet, I got my first one a few days ago, but the hashing boards are all more or less the same and made of 2 things:
-Hashing chips
-Voltage regulators
The voltage regulators and electrolytic capacitors are often the culprits for non working material

I have an S1 with 8 of the 32 asics show up as "x" on 1 blade. I have tried rebooting it without tuning off the psu. I have tried rebooting after turning off the PSU, after unplugging the PSU, unplugging the S1 from the PSU etc. I'm at wits end here. At one point in time the green LED started flashing again but it was like it was trying to hash at full speed but wouldn't. The LED would go steady as usual then similar to a lightbulb that is about to die (random blinks before death kinda deal) It's since stopped doing that though and the machine only hashes at about 100GH. I looked over the board and don't see anything burned up. Any suggestions?
someone told me to put it in the freezer for a day and then let it come back to ambient and restart it. I don't think that would be a permanent fix though.
