Antminer S3+ problem

[Totyamuri]

Hi guys!

I have a problem with my antminer S3+, the thing is that just half of it works, one of the boards doesn't want to.
In the miner's info it just shows: -------- --------
The PSU is soldered to the miner, and it worked, just for now it has stopped working.

Please help me, guys.

Thank you,
Totyamuri
