Bitmain Antminer S2 Bitcoin Miner Stopped Booting - How to get it to boot up again? I have a S2 Antminer since April 2014, and has been on for 6 months and stopped working recently (oct-2014). I can turn it on and it shows power, but the LCD is blank and when opening the cover to see if there is anything loose, everything seems fine. I tried to take out the microsd card that is connected to the controller card inside and I cannot seem to be able to see it on my computer. It doesnt detect at all. 

I tried following the instructions here: https://bitcointalk.org/index.php?topic=671625

I purchased a Beaglebone Black Rev. C from Amazon. The instructions found on that page doesnt seem to be very clear as I needed to improvise on certain things. Does anyone have a better guide or tips on how to get this working?

If you bought your S2 from bitmain, ebay or amazon, contact the seller as the S2's have a 1 year warranty from manufacturer.

Bitmain now has a repair center in Denver, so the unit would not have to be shipped back to Hong Kong.
