I have a few NewPacs and one of them had been underperforming the rest and now it seems like it is on it's last leg. All of them are on a Gekko hub with a high speed server fan blowing down on them to keep them real cool.     Now  I can't get it running at standard frequency (100) with any type of consistent results.    I have changed the voltage a bit to see if that would help, but everytime I try it, the output looks like this:

The green LED is on all the time and the white one is on when powered on and then goes between on and off while the cgminer is running.

Any thoughts?    Is there a way to confirm what the voltage is out of the adjustment pot?

Thanks
