Here is a guide for PCB: https://bitmain.zendesk.com/hc/en-us/articles/204875015-How-to-diagnose-S5-hashing-PCB
I would use that first to make sure it looks good hardware wise. It is not bad to check it anyways.
And here is a guide if it does seem to stick around 500-600 area after: https://bitmain.zendesk.com/hc/en-us/articles/203559969-My-S5-hashes-at-about-600GH-S
Please let us all know if that works for you! Best of luck.
Unscrewing the screws for the board, i notice a stripped screw head.
Is it stripped to point you cant unscrew? I don't want you to do any damage.
If we cannot go through PCB guide I would go to other guide: https://bitmain.zendesk.com/hc/en-us/articles/203559969-My-S5-hashes-at-about-600GH-S
It is more software then hardware. But it's worth trying it.
It's a stripped screw and I don't want to damage it. I was able to move the PCB and check both boards individually. I have a dead board, and 1 chip dead on the other board. It also isn't hashing. This is not a good day. 10 miners and this is the first miner to do this. ARGGGGGG.
What are the next steps?
Do you know if it's still in warranty? Did you buy direct from Bitmain?
Next step you will need to contact Bitmain Warranty. They will have to help as far as parts. Below is the ways to contact them:
