I just received some S9's, of the bunch it appears I have two dead boards. I tried different PSU's on each miner, rebooted, updated firmware etc and nothing improved. I know this is beating a dead horse around here, but any thoughts on what may be wrong? I'd like to learn to fix these myself, is there a good thread around here that covers most issues with these boards?
Here's the screen shots of my status page for each miner with a dead board:

I'm gonna try a Bitmain support ticket, I expect they will want to ship the who miner back... Recent posts suggest BitmainWarranty.com hasn't been active?
Thanks very much, I'll return the favor when I learn more about this
