When I turn it on the PMU lights stay on for 20 seconds and then the lights goes off. It says 0 ghs.

Recently I changed both PMU boards. I don't believe that all 4 hash boards are burned in a day.

The AUC3 converter and the controller work because I have another avalon 841 and it works.

If someone has any experience would be kind to share it.
