hashboard not working after internet disconnected

[condourfx]

I have antminer S9 and the internet was disconnected for 1 hours and work again but I see one hashboard not working (the red led off)

I try do restart many time not work..

I check the board if burned or damaged but its fine and I don't see any damage .

I try connect this hashboard only but not working also .

Now I disconnect this hashboard and the others two board working good.

I've noticed when I connect and power on all hashboard ,the antminer Restart several times but two hashboard work good and the other one not working ( red led off)

how can resolve this problem ?

Thanks for reply

I try upgrade or change firmware I use this file to upgrade : https://shop.bitmain.com/files/download/s9-20160715-600M.tar.gz

I wait 20 minute after upgrade but nothing happened , I do reboot again and the all 3 hashboard work for 2-3 minutes normally and Hashrate increaset to 12 TH  but after that one board stop hashing ..
I think problem from firmware or control board because all hashboard can work but one of them stopped , I will try replace control board or try use another firmware , What you think ?

Chances are you have a bad board. Please post the kernel log after booting and hashing for a bit. This will greatly help in troubleshooting the issue.
