Why is the reversing camera of the dash cam not displaying?
2 Answers
The most likely reason for the reversing camera displaying a black screen is poor line contact. It is necessary to promptly check the wiring and the connection points of the vehicle installation to see if there is any loose connection. If found, simply reconnect the loose parts properly. It could also be due to aging of the video power cable, in which case trying a new power cable may help. Additionally, prolonged use of the reversing camera can lead to poor chip light sensitivity, resulting in a snowy screen. Below are some relevant details: System issue: The dash cam itself has a system, and if there are problems with the system, it may cause crashes or reboots. Detecting and fixing the system is key to solving this issue; usually, restoring factory settings can resolve it. Memory card issue: Hardware problems are more likely related to the quality of the memory card. Many car owners opt for cheap memory cards online, but low-quality counterfeit brand cards can cause data writing issues, leading to crashes and reboots. This is currently one of the most critical issues, which can be solved by replacing the memory card. It is generally recommended to choose a high-speed card.
I remember one time the reversing camera suddenly went black, which was really frustrating. I immediately pulled over to check: first, I looked to see if the wiring plug was loose or disconnected, gently shaking it a few times to test the connection. Then, I checked the camera lens for any dirt or water stains, as these can obstruct the view if not wiped dry after washing the car. I also went into the dashcam menu to confirm that the reversing assist function was turned on, as sometimes accidental touches can disable the settings. The fuse box is also located under the steering wheel, so I opened it to check if the corresponding fuse was blown—replacing it with a new one fixed the issue immediately. For routine maintenance, I recommend wiping the camera with a dry cloth every month to prevent dust buildup. If all these checks don’t resolve the problem, it’s best to head to a car repair shop right away to avoid compromising driving safety, as reversing relies heavily on visual assistance.
