Why is the Mercedes-Benz reversing camera screen black?
3 Answers
The reasons for the black screen of the Mercedes-Benz reversing camera are: 1. Poor line contact. It is necessary to check the connection between the line and the vehicle installation in time to see if there is any virtual connection; 2. The video power cord is aging. You can try to replace it with a new power cord; 3. The reversing camera has been used for too long, resulting in poor chip photosensitivity. Taking the Mercedes-Benz G-Class AMG 2020 AMG G63 as an example, it is a medium and large 5-door 5-seat SUV with a length, width and height of 4864mm, 1984mm and 1974mm respectively, a wheelbase of 2890mm, equipped with a 9-speed automatic manual transmission, and a maximum speed of 220 kilometers per hour.
Last time when I was reversing my friend's Mercedes-Benz, the rearview camera suddenly went black, which scared me so much that I immediately stopped to check. Probably the camera lens was covered by mud, which is common during the rainy season—just wipe the lens with a damp cloth and it should work again. Or maybe the wiring connection got loose; open the trunk and check if the connector is secure. If that doesn’t help, try restarting the engine—sometimes the system freezes. If it’s still black, the camera might be broken or there could be an issue with the screen, requiring a technician to fix it. After experiencing this, I realized how risky it is to reverse without the assistive display, especially in the dark when obstacles are hard to see. I recommend addressing the issue promptly. Regular maintenance, like cleaning the camera during car washes, can prevent such problems—safe driving often relies on these small details.
Since I started learning auto repair, I've focused on electronic systems. The causes of a black screen in Mercedes-Benz reversing cameras aren't hard to diagnose. Typically it's either a camera malfunction (like lens contamination, water damage, or impact damage), wiring harness issues (loose connections or breaks that often occur on bumpy roads), or display unit failure/software bugs requiring updates. My advice: first clean the lens and check wiring connections. If that doesn't work, reboot the vehicle system by turning off the engine for 10 minutes. Mercedes circuits are precision-engineered - avoid disassembling blindly to prevent shorts. Regular fuse and connection checks can prevent black screens, avoiding driving hazards.
