What are the reasons for the car rear camera not displaying?

The reasons for the reverse camera not displaying are as follows: Damaged or obstructed camera: If the camera is damaged, the image cannot be uploaded to the computer, so it won't display. In this case, you should go to a repair shop or 4S store for maintenance, and if necessary, replace the camera. If there is just an obstruction blocking the camera, simply remove it. Damaged display screen: When the display screen remains black and won't start or shows distorted images, it is usually damaged. This situation requires inspection and repair at a repair shop or 4S store. Poor wire connection: If you frequently drive on rough roads, the bumpy environment may cause the internal wires of the car to loosen or detach. When the wire connection is poor, the image from the camera cannot be transmitted to the main unit, and the reverse camera won't display. This situation requires dismantling the center control panel for inspection.
When my rearview camera suddenly stops displaying, my first thought is that it might be due to a malfunction in the camera itself, such as water entering the lens or internal circuit failure, especially during heavy rain seasons—water seepage can cause a short circuit, resulting in a black screen. It could also be a power supply issue, like a blown fuse or insufficient battery power. I check if the reverse lights are still on because sometimes they share a fuse; if they’re not lit, it’s likely a fuse problem. Loose wiring or corroded connectors are also common causes, as frequent opening and closing of the trunk can cause vibrations that disconnect them. System software bugs might also be the culprit, and restarting the infotainment system sometimes resolves the issue. Additionally, a faulty display screen can be mistaken for a camera problem. This severely impacts reversing safety, so I recommend pulling over immediately to inspect or seek repairs. To prolong the camera’s lifespan and reduce risks, avoid exposing it to direct sunlight or water in daily use.
