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

The reason why the car's reversing camera does not display is poor line contact. Below is relevant information about the reversing camera: Solutions: Camera malfunction: If the internal components of the camera are damaged, they need to be replaced. If the power supply to the camera is loose, it should be securely plugged back in. Damaged wiring: The entire length of the wire from the camera to its power supply should be carefully inspected without any blind spots. If any breakage is found, the wire ends should be reconnected and sealed with tape. Camera blockage: Use alcohol or similar substances to clean and dissolve any dirt. How to interpret the reversing camera display: A green line indicates that the obstacle is far from the rear of the car, and reversing is safe. The area marked by a yellow line is 60 cm from the parking space, requiring caution when reversing. The area marked by a red line is 300 cm from the parking space, and reversing should not continue. When an obstacle enters the yellow area, it is 2 meters away from the car. When it reaches the last section of the yellow line, the distance is only 10 cm.
I've encountered the issue of the reversing camera not displaying several times, which is quite a common nuisance. The camera itself might be faulty; getting water inside during car washes or hitting obstacles can easily cause this. Wiring connection problems are also widespread, as the wiring harness near the tailgate is frequently pulled, and loose or corroded connectors can lead to signal interruptions. The screen not switching to reverse mode might also be due to a malfunction in the vehicle's infotainment system, software glitches, or incorrect settings—try restarting the car's power and waiting a few seconds before turning it back on. A blown fuse is not uncommon either; excessive current in the main circuit can burn it out, and replacing it with a new one from the fuse box should solve the problem. Additionally, in winter, the camera might freeze over and become unusable—cleaning it off could help. This issue relates to driving safety, so don't take it lightly. It's best to get it checked at a 4S shop or repair station as soon as possible. Last time, I almost backed into a wall because of this, and only after spending money on repairs did I feel at ease. Remember to regularly inspect the rear components of your car to extend their lifespan and save money.
