Hello guys, I know this is not the best place to post this problem, but as I know you are the best and smartest guys over here please help me with this if you are able:
I've been mining in kano since six months I think and from yesterday I realized my TH/S dropped a lot and I went to check my miners and I found this:
I have an Antminer S9 and it got in the chain #8 GH/S(RT) = 0.00000
I've seen in the forum some problems about that and says it is a board problem.
My antminer is out of warranty, and I am not able to send back to bitmain to get a repair ticket because it is almost impossible to send it from my country. So please help me guys Sad I'm really worry about that Sad
Here is a picture of what I'm telling you:

You need to post a screenshot of the full page for seeing all chips. but it looks like you have a problem with 1 hashing board; should send to bitmain for repair or purchase a hashing board and replace it at your own risk.
I also highly recommend to have a 2nd and 3rd mining address for backup (not just the 1st one).
