What is the reason for the Buick Excelle's reversing camera not displaying?

[StLucia]

The reasons for the reversing camera not displaying are poor line contact and prolonged usage. Below are the specific reasons for the reversing camera not displaying: Poor line contact: It may be due to poor line contact. It is necessary to promptly check the connection points between the lines and the vehicle's installation to see if there is any loose connection. If there is, simply secure the loose connection properly. Naturally, it could also be due to aging of the video power cable, and trying to replace it with a new one might help. Prolonged usage: If the reversing camera has been used for too long, the chip's light-sensing effect may deteriorate, leading to a snowy screen appearance, or even a black screen in severe cases. This indicates hardware damage. The reversing camera is also known as a parking assist system, or reversing visual system, or onboard monitoring system. This system is widely used in various large, medium, and small vehicles for reversing or driving safety assistance.
