Repair of Leaf Aptus 22

[MartinN]

I have an Leaf Aptus 22 that has developed malfunction. The back says 'Insert storage card' and the card writing LED blinks red when inserting a CF card of any age and size. The firewire powers the back but there is no connection to Leaf Capture software. What I understand the 'firewire board' is defect. However, I want very much repair this back but I think the only solution is to wait for some electronics guru to start servicing old backs.

BTW I have not tried Capture One Pro because I only have DB/Express versions.

Any tips on very skilled independent electronical camera repair ?

I recall reading discussions on changing the internal battery but it sounds like you may need parts. At the age of the back, Leaf may not even offer repair service. The combination of poor parts availability, absence of service manuals and complicated circuits may make purchasing another used back a cheaper solution. Good luck

Hello
I experienced exact same issue on one of my Leaf Aptus 75 with V mount. I got another working one on eBay.
I exchanged the corresponding components of two identical backs with each other, and finally found which PCB board caused this issue you mentioned. It's the PCB board with Power PC CPU.
After I changed this broken board with working one, the issues you mentioned disappeared completely.
So the easiest way to repair it is to get an Ebox of this back and change the broken one with the working one. Of course, if you want to do, you can just change the Power PC PCB board only.

Hope this helpful.
