What are the reasons for sudden black screen in car reversing camera?
3 Answers
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.
I'm an electronics enthusiast with some knowledge about rearview camera systems. A black screen usually involves camera failure, video cable short circuit, display issues, or system control errors. Possible causes include water damage to the camera circuit, broken cables causing signal interruption, burnt-out display screen, blown fuse cutting power, or bugs in the smart control module. The camera operates at around 12V power supply - just locate and replace the relevant fuse in the fuse box. Use a multimeter to test voltage and confirm circuit continuity. For software upgrade errors in Hyundai vehicles, try restarting the infotainment system or visit a dealership for reprogramming. Moisture corrosion in connectors often causes problems, so I regularly check cable routing to prevent bending and aging. When black screen occurs and rear visibility is lost, stop reversing immediately and find a safe place to troubleshoot, as this poses significant safety risks.
