Whatever happened to all the Leaf Aptus backs?

Did they all stop working?

I'm asking because I took mine (Aptus 75) out of its careful dry storage, charged up a couple of batteries and turned it on.  Result was a corrupt image. 
 
I always assumed that carefully stored electronic gadgets would just last, but now I understand that some components like electrolytic caps, and contacts might oxidise. I'm wondering about sensors and if they are prone to degradation.
 
Curious if anyone else has had a comparable experience.

I had a second hand leaf aptus 2 5 for 5 years before I switched to phase one p65+ 3 years ago.I sold the leaf in this forum and I know it is still going strong in the hands of the new owner. Maybe you can find a good electronics technician to give your back a look

I have been wondering this too. Been REALLY looking for a leaf aptus 56 for a long time now

Make sure the CF card is an old-enough type. Also the camera shutter or connection/ cable to the back might be playing up
