Fluke 5100B Calibrator

Description

Up here is a  Fluke 5100B I've had for about 14 yrs.I used it quite a bit at one time.It worked fine . on my previous job after the contract ended I shipped it and my other equipment and tools to my home and it has been sitting on a bench in my shop.I hadn't turned it on since I got back 4 yrs ago and I don't really have a use for it now.I  turned it on and it powers up but the display will only come on briefly when I turn it off .It was working before I shipped it but evidently something has gone awry .The on switch sticks when engaged and when you pull it back the display will flash on briefly.Maybe some cards have unseated or the switch is bad.Trying to clean out stuff  AS IS .Hope someone can get it going again.Thanks for looking.Questions feel free
