Why is the reversing camera screen black?

The reasons for a black screen on the reversing camera: The wiring for the reversing video is not connected or there is an issue with the reversing camera and its circuit. The reversing camera is part of the car's monitoring system, and the commonly used 360-degree panoramic reversing system ensures no blind spots when reversing, enhancing the safety index of the vehicle. The 360-degree panoramic reversing system displays videos from four cameras on the screen, capturing the situation from various angles. When problems occur with the reversing camera, such as a black or blue screen, timely repair or replacement is necessary to avoid affecting the normal use of the reversing system and creating safety hazards during travel.
The reversing camera screen going black is an issue I frequently encounter at the repair shop. The most common cause is the camera lens being covered by mud or dirt, which interferes with signal transmission. Sometimes it's due to loose wiring or a short circuit, such as when rainwater seeps into connection points causing corrosion. Blown fuses are another frequent issue, especially in older vehicles where excessive current can easily cause them to melt. Additionally, display screen problems are common, like software bugs requiring a system restart. From a safety perspective, a black screen while reversing increases the risk of accidents. My advice is not to panic when the screen goes black; instead, slowly use the rearview mirror and rear window to reverse, or engage the handbrake and check the rear manually. Finally, it's best to clean the camera and inspect the wiring during regular maintenance—prevention is key, saving both money and hassle.
The root cause of a reversing camera black screen typically lies in electronic system issues. Signal transmission interruption from the camera module may occur due to physical damage or signal interference; short circuits or breaks in the video cable within the wiring can directly lead to a black screen; there's also the possibility of a blown fuse, which protects the circuit but cuts off the power supply; display screen malfunctions should not be overlooked either, such as conflicts arising from incomplete software upgrades. From my observations, poor wiring connections during navigation system modifications are the most common trigger for this issue. It's advisable to maintain a habit of system reboots while driving or to connect diagnostic tools for self-checks. Long-term preventive measures include avoiding frequent engine starts to reduce current fluctuations that could harm electronic components.
