Seeing if anyone may have seen this problem.  I am going to try re-seating cards... but...

After return from an on-site calibration job by techs, when powering up one of our Fluke 5500A's, it goes as far as the screen message,
"FLUKE 5500A (2.61) Initializing analog hardware..."

Then just hangs there.  Any quick fix ideas on this?

UPDATES:  I connected it to a GPIB, and I can send commands to it.  It responds to a *IDN? identification command, the OPR light turns on when I send an OPER command, and if I tell it to output DC volts, ohms, or AC volts (haven't tried others), then follow up with a query, it receives the commands, but doesn't actually output any of the values.  So the digital part seems like it THINKS its working, but nothing analog is actually happening.

I've got about three of them down right now for differing problems.  I found a partial fix for it, but I can't remember.  Maybe when I have one open, I will remember which board it was.  I did some board swapping and found a board that made some of the problem go away.  Problem is, I am so overly busy that I don't have enough time to work on it.  I do need to get back to it, and I'll try to remembe to post when I do.
