What causes the car reversing camera to have no signal?
2 Answers
The reasons for no signal in the car reversing camera include: 1. Poor line contact; 2. The camera has been used for too long, resulting in poor chip photosensitivity; 3. There is a defect in the car circuit. The reversing camera is also known as the parking assist system, or the reversing visual system, or the vehicle monitoring system. This system is widely used in various large, medium, and small vehicles for reversing or driving safety assistance. The reversing camera system can also see clearly at night through infrared rays, and the vehicle probe has anti-magnetic, anti-vibration, waterproof, and dustproof performance. The vehicle display uses TFT true color, has been treated with anti-magnetic to eliminate signal interference and flicker, can receive two videos at the same time, and can play VCD and DVD without a decoder.
I'm an ordinary office worker who commutes by car every day. That day, while reversing, the screen suddenly went black and the reversing camera showed no signal, which gave me a real scare. I quickly parked and checked. Thinking back, it might have been because I was driving on a muddy road, and the mud splashed onto the rear camera, blocking the lens and causing the signal to cut out. I tried gently wiping the camera surface with a damp cloth, and after restarting the car's power, the image returned to normal. If cleaning doesn't work, it's likely due to loose connections or aged and broken wires, which would require a visit to the repair shop—don't try to fix it yourself and risk damaging the system. Although the reversing camera is convenient, it can still fail. It's recommended to clean the camera quarterly to avoid dust buildup causing issues. If you encounter this problem, don't panic—safely pulling over should be your first priority.
