I had powered it off and on several times thinking that I wasn't giving the blades long enough before turning on the controller, because bitmain says it matters. It always showed all 3 blades were good.
hard power resets are not a good idea. try software rebooting
I have a thread on it.
https://bitcointalk.org/index.php?topic=1196671.0I now get 4775 to 4825. I do a software reset every 2 days or so.
1) click system
2) click reboot this does not reboot it takes you to step 3.
3) click reboot this reboots.
Takes about 2 minutes to reboot. check stats a few times. in the next hour or so. once the hour is up
if your hw reads more then 0.11 chances are the reboot did not do the job
if your hw reads less the 0.02 chances are the reboot will help hash rate
