Why is there no signal in the car's reversing camera?

[SanMila]

Here are the reasons why there is no signal in the car's reversing camera: 1. The operation of the reversing camera may be interfered with when the car is just started. 2. The probe of the reversing camera is damaged or the photosensitive signal of the chip is blocked due to prolonged use. 3. Poor line contact may cause the reversing radar to be intermittent. 4. The navigation card slot may be damaged, causing the reversing camera function to fail. Here are the solutions for no signal in the car's reversing camera: 1. The operation of the reversing camera may be interfered with when the car is just started. You can try restarting to check the situation. It may also be electromagnetic interference from other electrical devices in the car. Try turning off the radio or music player before restarting. 2. If the probe of the reversing camera is damaged or the photosensitive signal of the chip is blocked due to prolonged use, you can remove the camera and connect it to someone else's navigation system to test if the camera is damaged. 3. Poor line contact may cause the reversing radar to be intermittent. Check the connection points between the reversing radar lines and the vehicle's wiring for loose connections. 4. If the reversing camera in the car is part of an integrated navigation and reversing camera system, the navigation card slot may be damaged, causing the reversing camera function to fail. When selecting a reversing camera, pay attention to whether it matches your vehicle model. Consider factors such as the camera model, power voltage, screen size, waterproofing, shock resistance, and anti-interference capabilities. Cars generally use a power voltage of 12V, while large vehicles such as trucks and buses usually use 24V. The reversing cameras for cars and large vehicles should not be mixed.
