Mine looks like that too -- it was working for a day or two. It was too loud in my office for me to even speak on the phone, so last night I removed the pull-fan fro one of my S3's and replaced the S5's push fan with it -- had to splice to extend the wires because they didn't reach.
Now it is nice & quiet, and still running at acceptable temps < 65
BUT chain #2 is dead -- all dashes :-(
How do I go about troubleshooting? I reseated all of the power connectors (twice), and the two grey data connectors on top. But I'm not sure what to try next. My warranty is clearly null and void :-)
thanks,

I had some zeros drop off my chain and was only hashing at 450 or something similar. I unplugged the miner. Removed the two black sides, visually checked everything over and slightly tightened the screws with the springs. I found a few really lose. I don't know the torque setting to use, but I was very careful and used a little drive where I couldn't over tighten at all. Some times just doing things like that to these miners make them work when powered up again and it did. Got all my zeros back and hashing power. I also re-seating the ribbon connections. I have no idea why that would "fix" anything, but if it works, don't knock it.
