What are the reasons for sudden black screen in car reversing camera?

The reasons for black screen in reversing camera display mainly include three points. Below is a detailed introduction about these three reasons: 1. Aging of video power cable: When the video power cable ages, you should promptly try to replace it with a new one. 2. Wiring issues: This is the problem with the highest failure rate, because the wiring harness of the reversing camera runs from the instrument panel all the way to the trunk, which is a long route and can easily lead to poor contact at a certain point of the wiring harness or plug. 3. Prolonged use of the reversing camera: When the reversing camera is used for too long, it can easily lead to poor chip photosensitivity, resulting in a black screen.
That day when I was reversing, the reversing camera suddenly went black, which really worried me. I immediately stopped to check. I found the camera lens covered in mud and dust, and after simply wiping it with a damp cloth, the image was restored. I asked a few driving friends, and they all said this is quite common, with possible causes including lens dirt, loose cable connections, or a blown fuse. The reversing camera system is fragile; frequent driving vibrations can easily loosen the plugs, and cables in the trunk getting crushed by items is also a frequent occurrence. For safety, I now clean the camera every time I wash the car; if the screen still goes black after cleaning, I check if the fuse has blown or if the camera itself is damaged. Reversing without the camera is risky, especially in narrow alleys, so I have to be extra careful and rely more on the rearview mirrors.
