Good morning, people

I have a S9 (latest firmware) with low hashing rate chain, and seems to be normal, no "X" on chips, but it shows 0 in hw and no temperature since bootup (it's cold at the beginning). I've cleaned all the chains, tried another PSU, checked all the capacitors, and they seem to be ok.

Any ideas?

Thanks!
