Thanks for the response. I hooked up another power supply from a running s7.
If you're out of warranty I would say try swapping the controller board from the working unit on to the dead unit.
I am out of warranty, I'll give that a shot. Thanks
If your running S7 is also out of warranty, you might be able to check your blades from the non-functional one by swapping them into the functioning one, a single blade at a time. You would need to do this methodically and with care to draw useful conclusions.
How many actual ports are on you functional S7 controller? Is it just the three, or does it have all 9 populated? If you can narrow it down to the controller, then I am pretty sure that Bitmain will sell you a new controller.
You should be able to figure out what's broken at a gross level, and see what bits of your "broken" S7 can actually still be used.
I should also ask, are the two S7's you mention from the same, or similar, batches? That might influence what you can do in terms of moving parts around.
Best of luck.
