The reasons for the sudden failure of the reversing camera to display are: 1. Poor line contact: The black screen phenomenon of the reversing camera is most likely due to poor line contact. It is necessary to promptly check the connection between the lines and the vehicle's installation to see if there is any loose connection. If so, it will cause abnormal imaging of the reversing camera, and in this case, simply reconnecting it properly will suffice. 2. Poor photosensitivity: The reversing camera has been used for too long, resulting in poor chip photosensitivity, and even the appearance of many snowflake-like phenomena. It needs to be inspected and repaired at a repair shop or directly replaced.
A few days ago, my reversing camera also went black, which really worried me. Later, I found out it was because the rear trunk camera was covered in mud and rainwater—cleaning it fixed the issue. If the camera itself is fine, then you should check if the wiring is loose, especially since frequent opening and closing of the trunk can pull on the wiring harness. Also, don’t forget to inspect the fuse—my friend’s car once had a blown fuse shared by the reversing camera and reverse lights. A frozen infotainment system could also cause this; try restarting the car. If it’s just rained, pay extra attention, as water short-circuiting the wiring is quite common. If the camera itself is broken, you’ll need to replace it. If you’re handy, you can do it yourself; otherwise, a repair shop can handle it for a few hundred bucks.
