you have a dead board.
try running braiins software and two boards.
I would tell you buy an epic controller from altairtech.io
https://altairtech.io/product/epic-umc/but it is costly to do that. like $150
epic controller will run 2 boards.
you could replace the control board to hashboard communication wire.
https://altairtech.io/product/antminer-ribbon-cable/you could reseat the one not working.
likely fix is either braiins and run two boards or epic and two boards.
a score is reseat the 18 pin ribbon and it works as that is free.
