You have 2 chains that are not hashing. The ones showing 00 in temp and BB in status.
1st check your power. Could be a bad power supply or one just not putting out enough.
Check the ribbon cables form the controller board to the has boards.
Other than that, there is not much you can do. Boards go bad often, it sucks but not much you can do about it.

Pretty much that is it. They had many issues when they came out. Even if you had warranty on them, sometimes it was troublesome getting them warrantied. Hence why I stopped buying Antminers.
What you need to do is basically take it apart and check for anything burnt, I am assuming you will find some burn marks on certain hash boards. If there are burn marks see what burnt, if its a capacitor you might get away with replacing it, however chances are the boards are garbage.
Don't feel bad, they only had 2 more months of mining left anyways.
i have checked power cables, and power supply (bitmain apw7). and the cables, no visible damage to the cables either.
Do you know how much the caps values are ?
i have not taken the miner apart, since im making 0,01eth still
