Well I was a away from home today and my internet went down. When I got back home it was up and running and the miners were acting funky. I powered them down and they all came back up right, but the S5 didn't. I noticed I am stuck around 500 to 600. I'm going to go through the steps, but anything upfront would be greatly appreciated. Miner was running fine up to that point of the internet going down. The second chain is completely dead. Thanks in advance.
Here is a guide for PCB:

And here is a guide if it does seem to stick around 500-600 area after:
