What are the reasons for the sudden failure of the reversing camera to display?

The reasons for the sudden failure of the reversing camera to display include damage or obstruction of the camera, damage to the display, poor cable contact, or a dead battery. The specific explanations for these reasons are as follows: Damage or obstruction of the camera: If the camera is damaged, the image cannot be uploaded to the computer, and thus it cannot be displayed. In this case, it is necessary to go to an auto repair shop or a 4S store for maintenance, and if necessary, replace the camera. If there is only an obstruction by debris, removing it will suffice. Damage to the display: When the display freezes or the screen flickers, it is generally a sign of damage. In such cases, it is necessary to go to an auto repair shop or a 4S store for inspection and repair. Poor cable contact: If the vehicle frequently travels on rough roads, the shaking conditions may cause the internal cables to loosen or detach. When there is poor cable contact, the interface connected to the camera cannot transmit data to the host, and the reversing camera will not display. This situation requires disassembling the central control panel for inspection. Dead car battery: When the vehicle is turned off and the lights or multimedia system are used for a long time, the battery may become depleted. When the battery is low or shut down, the vehicle's multimedia video system will not function, and the reversing camera will not display. In this case, charging or replacing the battery will solve the problem.
The other day when I was reversing, I suddenly found the rearview image disappeared, which made me panic instantly – I’ve gotten so used to relying on it for precise parking. I immediately stopped the car, turned on the hazard lights, and checked. Maybe mud or water splashed onto the camera lens, blocking the view, or perhaps I accidentally loosened the connecting cable when opening/closing the trunk last time. Another possibility is a blown fuse, especially since those small fuses for car electronics often fail. I tried wiping the lens with a towel myself, but if that doesn’t work, I’ll have to visit a repair shop to check the wiring. Recalling forum discussions, some mentioned short circuits are common after rain. My car has aftermarket equipment, so the interface might not be properly secured. Such issues shouldn’t be delayed—safety comes first to avoid scraping walls or injuring pedestrians while reversing. Better address it ASAP to prevent bigger troubles.
