Why does the reversing camera show a blue screen?
2 Answers
The reasons for the reversing camera showing a blue screen are: 1. The camera or video line has a fault; 2. The display has no video signal input and will show a blue screen; 3. Poor contact with the camera. The methods to check the reversing camera blue screen issue are: 1. Check the reversing radar wiring and the installation connection points for poor contact; 2. Check if the reversing radar sensor has a fault; 3. Check if the reversing radar itself has any defects or damage. The car reversing camera is a system that allows intuitive and clear monitoring of the video images from both sides and the rear of the car inside the vehicle, helping to avoid accidents and theft.
I've experienced the reversing camera blue screen issue several times, often due to dirty camera lenses. For example, mud splashes after rain or moisture intrusion can block the lens, causing signal interruption and displaying a blue screen; restarting the vehicle might temporarily fix it. Loose or aged wiring connections are also common, especially when cables rust from long-term neglect. If the vehicle's electrical system, like the battery, has unstable power supply, the camera module may short-circuit and show a blue screen. Whenever this happens, I immediately clean the lens and wipe the connectors with a cloth; performing a small inspection every two months can prevent issues. Ignoring it might burn out the reversing camera components, leading to costly replacements and affecting nighttime reversing safety. Developing a habit of keeping the camera area clean reduces the risk of malfunctions.
