Why does the reversing camera screen always flicker when reversing?

Generally, it's an issue with the reversing camera, which can be resolved at a 4S shop. Below is relevant information about reversing cameras: 1. Introduction to reversing cameras: A reversing camera, also known as a parking assist system, reverse visual system, or vehicle monitoring system (English name: vehicle-backup-camera), is widely used in various large, medium, and small vehicles for reversing or driving safety assistance. 2. Advantages of reversing cameras: Installation is simple. Typically, a standard single-output reversing camera only requires connecting the positive power wire to the positive terminal of the car's reversing light power and the negative power wire to the negative terminal of the reversing light or to ground (GND). Wiring can be easily understood by studying the vehicle model, and the camera can be installed by drilling a hole in an easily accessible location.
I just encountered the same issue. My car's screen also kept flickering when reversing. I initially thought the camera was broken, but it turned out to be caused by moldy and loose wiring connections. Check the wiring harness for the rearview camera in the trunk yourself—give it a gentle shake, and if the flickering worsens, it's likely a poor connection. This could be due to moisture intrusion during the rainy season or significant voltage fluctuations, especially when the car battery is old and unstable. I recommend first cleaning any dirt off the camera lens and securing the connection wires. If it still flickers, don't force it—take it to a professional auto repair shop to replace the connectors or upgrade the system. It won't cost much but will ensure safe reversing. Such problems are quite common, especially in older cars or after frequent long trips. Regular maintenance of the wiring to prevent dust buildup can effectively avoid these issues.
