Antminer S9 board problem

[Riddla149]

Hey guys I'm only getting 9k th/s on one of my S9s. I have tried to find info on it, but I havent found something close to what the chips look like here. Here is my screen cap. Any help appreciated. https://imgur.com/a/ztZ35

One of your boards is bad. You will have to pay if you want it repaired.

That blows. How do I go about doing that and getting it out? Any idea on what they charge for something like that

Any S9 sold this year has a 180 day warranty. If you are still in warranty just go to your bitmain account and submit an RMA. Otherwise you would have to contact a place like bitmainwarranty.com. They have you send the system in, they diagnose it, then they give you a repair price.
