RF 100-500 bayonet mount change problem

I had to change the mount on my RF 100-500 as it was damaged - the lens would detach by itself.  Other than that the lens was working perfectly. I replaced the mount - an easy enough procedure just requiring one ribbon cable to be disconnected and then reconnected.  Now the lens does not communicate with the camera at all.  There is no error message, but I cannot set the aperture and the autofocus does not work.  I have tried reconnecting the cable but it is still the same.

Is there a secret reset to the lens that I don't know about?  Anyone got any ideas on how I should proceed.

Thanks

Photos of the lens apart might help!
