What is the reason for the sudden loss of reverse camera image in a Mercedes-Benz?

It may be due to a camera malfunction or a loose or disconnected power cable. If it's a camera malfunction, you need to purchase and install a new one. If the power cable is loose, causing the camera to lose power, simply reinsert the power cable and ensure it is securely connected. If the cable is broken, you can use sealant to bond and secure it firmly to avoid being pinched and broken during driving. Below is additional information: 1. Reverse Camera: Also known as a parking assist system, reverse visual system, or vehicle monitoring system. English name: vehicle-backup-camera. This system is widely used in various large, medium, and small vehicles for reversing or driving safety assistance. 2. Precautions: The issue of the reverse camera not displaying often occurs in vehicles where the camera was installed aftermarket, primarily due to product quality or installation issues. To avoid future problems, owners who want to install a reverse camera should purchase high-quality products and seek a professional repair shop for installation. Otherwise, if there are issues with the wiring, troubleshooting can be very troublesome.
When dealing with similar issues, I've found that sudden loss of the rearview camera image in Mercedes-Benz vehicles is often caused by several technical factors. The most common issue is a malfunctioning rearview camera, such as a lens covered in mud or a damaged camera unit, which can interrupt the signal. Next is loose or corroded wiring connections, especially at the wiring harness near the trunk lid, where vibrations can easily affect the contact. Control module failure is another potential cause—Mercedes systems typically have a dedicated electronic control unit for the rearview camera, and software errors or module malfunctions can interfere with signal transmission. A blown fuse is also a possibility, as the rearview camera circuit has its own fuse, which can be burned out by excessive current. Additionally, a malfunction in the vehicle's display unit or an abnormal signal from the reverse gear sensor can cause the image to disappear. I recommend first checking if the camera lens is clean; if that doesn't resolve the issue, take the vehicle to a professional repair shop to diagnose the module and wiring. Regular maintenance of the camera area can help prevent this problem.
Last week when I was reversing into a parking space, the reversing camera suddenly went black without any warning, which was quite annoying. From experience, this issue in Mercedes-Benz cars is usually caused by a dirty camera or a system glitch. The camera at the rear is prone to dust accumulation or mud splashes, which naturally blocks the lens and makes it impossible to see anything; sometimes it's due to a loose connector, especially after driving on bumpy roads. Fuses are also common culprits—the small fuse for the reversing system might blow, cutting off the power supply. Another issue I've encountered is software failure; the Mercedes multimedia system occasionally has bugs, and restarting the car or holding down the center console button to refresh might solve it. But it's more likely a hardware problem, like when I took it to the repair shop before and found out the camera was internally damaged—replacing it for a few hundred bucks fixed it. Losing the reversing camera is dangerous, as it increases the risk of scraping or hitting something, so I immediately pulled over and avoided any major maneuvers until it was fixed.
