So I have to re-try getting a board RMA'd to bitmain. I bought a brand new PSU to try to power that board up hoping I was using a bad psu and there was still no go. For those of you who have fully opened their S7, what is the easiest method to getting the top off so I can remove the problematic board? I assume the top comes off because you can't simply slide the board out of the casing.

Remove the rectangular plate behind the fan, boards will slide out. But I would contact Bitmain before opening the miner.

Just remove the plate behind the fan and they do slide out? What about the piece sticking above the top of the miner where the pci-e cables are connected? That's not part of the hash board?

Yup, just removing the plate behind the fan will do. That plate is holding the boards in place.

Cool, I'll try removing it tonight. Bitmain already agreed to 'test' the board at their facility in china. Sucks I have to send it there, but the 3 TH hash I get from a $1600 miner really blows.

Good luck with your RMA.
I had bitmain OK sending back 2 dead hashboards, and they have had them for nearly 4 freeking weeks!
I've sent several emails and they have not responded, both via Ticket system and direct email. Not only am I out the dead hashboards, but also out the $100 shipping fee back to them. I also openned another ticket as I had a brand new batch 8 hashboard fail after about 10 days of hashing. No response on that either. Still waiting for the 5 day late payment on batch 1 too. I'd have to say, I'm sorely dissapointed with the service received from bitmain - especially given the amount of money I've sent their way in 2015.

I'm waiting on 2 dead hashboards to be RMA'd as well. They probably won't receive my boards until next week though. Hopefully I won't have to wait a month after that to get working boards.

When they replaced my controller it took over a month. However, I sent them 3 dead hashboards on Dec 23rd. I had the replacements in my hands on Jan 6th. Problem is that one of the replacement cards died after 10 minutes. I can't see any reason for it to die -ie: heat sinks still in place and no burnt smell. So back to working on another RMA for the same batch 1 S7. My Batch 8s are 1 month old and seem fine so far..."knock on wood".

That's Interesting! Wonder why they haven't replaced mine or even bothered to respond to email inquiries. They've had mine in hand since 12/14.
