I have an 07 Yukon Denali. Yesterday when I put the truck in reverse I noticed that my backup camera was out. The screen is blank except for the safety warning.

Any ideas on how to trouble shoot? I already checked and the camera is enabled in the radio setup.

Is there anything blocking the backup camera lens? Disconnection is another possibility. These are just suggestion, not a diagnosis. I encourage you to take the vehicle in for an inspection. A certified technician will be able to offer an accurate diagnosis after a physical inspection.

If you have additional questions, please feel free to contact me.

I replaced the backup camera with one off eBay and it works now.
