Heylo folks,

 Looking for a little help. I didn't notice when, but sometime within the past month or so, one of my S5's stopped hashing or would produce minimal hashrate. Today I reset it back to the factory default and it won't hash w/ the default config. On the Status dashboard, it shows 30 asics on one board/chain and 26 asics on the other.

 There's nothing visually wrong with it, to my eyes. Can you provide me with some guidance?

Swap PSUs, cables, and/or controllers with other miners, try to isolate the issue. It would be unlikely for both hashboards to go bad although not impossible. Take the plastic guards off and look closely for any physical damage/burns. That's roughly where my knowledge ends Grin, maybe others can help more.

Thanks! I'll let you know what I find.

First I discovered that the fan would work for about 2 minutes then just shut off. I replaced the fan w/ 2 corsairs I saw recommended elsewhere on this site, cleaned and reapplied thermal paste, and ran it again to find that one board is just toast. Looking at the board, I can see that a few of the asic chips have melted and seeped through the holes in the PCB.

Would anyone have a working replacement board for sale?
Edit: Or a suggestion as to where I could purchase one. I've googled for replacement parts and have looked on ebay already.
