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 guys, help me. I'm really sad about that

Here is a picture of what I'm telling you:
