Ah, okay...... so the issue has been somewhat narrowed.  Unfortunate that a weak connection may be the culprit. Just as a point of reference I had something similar happen a few months back where it would start hashing and then immediately fade to nothing.  Turned out there was too much draw on the one supply I was using although it was the same it had always been.  I changed psu's and "eh voila" it was back.  Still running strong at 738.   As you replied to me on e-Bay I am interested and do have several Newpacs available that are no longer in use if you're interested in a trade/exchange.  Would be great if you could get the pod sorted first of course, ha ha.
