2014 Broadway EK camera problems

My monitor shows blue with no signal.
Anybody any ideas where I might find the wiring and connections for the reversing camera. I can't find any obvious connectors and I don't want to cut any holes below the camera in the cupboards unless I can be certain where the connectors are.
Many thanks in advance

Thanks for your help, I'll try it over the weekend

I had a problem with my Broadway EK camera from new. I was offered the option of a hole in the kitchen cupboard (as photo) or removal of the whole back of the cupboard which was my preference. There is no obvious repair.

After a new camera and two new monitors it was determined that there was a wiring fault between camera and monitor. I was told that this wiring was not accessible (roof?) so the electrician installed complete new wiring under the van. I don’t think the camera is accessible from the outside but I guess this depends on the model.
