CK5 miner 0 hashrate

Hello all crypto enthusiasts.

I have a CK5 miner whose hashrate has suddenly dropped to 0 in the backend interface.

The strange thing is that it doesn’t show errors on the miner itself and it connects fine to pools with the green icon.

I’ve tried the debug command, but I’m not getting much out of it.

Maybe one of you experts can help?

so far i have tried:

Reset to factory settings

3 different pools

Other internet

disassembled miner to see if there are breaks in cables etc.

look at chips in debug

The strange thing is that everything looks normal and the green led is flashing but i still get 0 hashrate?

i can se the temps on the hashbords are ok also?

hope someone wise can help

because I am without a leader by now.

unfortunately, there is no longer a warranty on it, and it has run flawlessly for several years

ohh, and i have upgraded to the new firmware also

There may be a problem with the control board.

You can try replacing it pool,F2pool or Dxpool
