Why is there no signal in the car reversing camera?
2 Answers
The reasons for no signal in the car reversing camera are generally two: the data cable connected to the reversing camera is detached or has poor contact, or the reversing camera is damaged. The following are the solutions for no signal in the car reversing camera: 1. Restart: When the car is just started, it may interfere with the operation of the reversing camera. You can try restarting to see the situation. It may also be electromagnetic interference from other electrical devices in the car. Try turning off the radio or music player and then restarting. 2. Remove the camera: The probe of the reversing camera may be damaged or the photosensitive signal of the chip may be 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 broken. 3. Check the wiring: If the camera lights up, it means the hardware of the camera itself should be fine. No signal means the camera signal is not transmitted to the display. Check the signal wiring of the camera. 4. Navigation card slot damage: If the reversing camera in the car is part of a navigation and reversing camera integrated device, it may be that the navigation card slot is damaged, causing the reversing camera function to fail.
I often use the reversing camera when driving. One time, the screen suddenly displayed 'No Signal,' which was quite concerning. After checking, I found that the camera lens was covered with mud or dust. Cleaning it with water solved the problem. Another common issue is a loose wiring connector. I opened the trunk and reinserted the plug tightly to fix it. If the camera itself is damaged, it might need to be replaced, with prices ranging from a few hundred to over a thousand yuan. Reversing without a signal is really dangerous, as it's easy to scrape the car or hit someone. So, I suggest stopping immediately and not reversing further—instead, go directly to a repair shop for a comprehensive inspection by a technician. Additionally, in cold weather, the lens freezing over can also cause problems, so it's important to take precautions against freezing in winter.
