Land Rover Repair: 2006 Range Rover HSE, range rover, coincidence

Question
I recently took my vehicle in for service where they replaced my brakes, had to replace navigation disc as they said most of the info was erased for some reason, replaced rear plate lite bulbs, and performed injection service.  When i picked the car up, i noticed the next day that the camera did not work.  it came on for a few seconds when i returned to the vehicle later but then flickered off.  it did this one more time the next time i took the car out but then went blank.  i returned it to service and told them i have never had a problem with the camera however they are saying the camera just went bad.  is it possible that a wire went loose or was damaged when in service?  
My car has 113,000 miles.

thanks for you time,
Jodi

Answer
Anything can break at any time.  

If you saw damage around the camera, I'd make a connection between the two events.  Otherwise, I suspect it is just annoying coincidence.  

The camera is not touched during any of the service you mentioned but of course I was not there, and have never seen your truck
