How to troubleshoot a backup camera issue in an Audi A6?

I have a 2017 Audi A6 and my backup camera has stopped working. I've tried restarting the car and checking the camera settings, but it still won't turn on. What could be causing this issue and how can I fix it?

It's possible that there may be a loose connection between the backup camera and the display screen. Try checking the wiring and making sure all connections are secure. If that doesn't work, you may need to replace the camera itself.
