Mine was more damaged than most. I knew that going in. It was mining on only 2 boards, then went down to 1. That also eventually died. So i knew all 3 boards were in need of some kind of repair. I imagine the repairs would depend on the problem with your machine.

That being said, they charged me $229usd per board for the repairs. I have another in one of my hosting facilities that I will be sending them for repair. Considering what miners are going for these days, I considered it a fair charge.

And yes, it has been running for 8 hours now and it is holding steady just over 54th/s (S17 53 th/s model), which is a little above where it should be.
