What Causes the Reversing Camera to Not Respond When Shifting to Reverse Gear?

[Derek]

Poor line contact or prolonged usage can both cause the reversing camera to not respond when shifting to reverse gear. Poor line contact: It is necessary to promptly check the wiring and the connection points where the lines are installed in the vehicle to see if there is any loose connection. If there is, it will naturally cause abnormalities in the reversing camera. In this case, simply securing the loose connection properly should resolve the issue. It could also be due to aging of the video power cable. Trying to replace it with a new power cable may solve the problem, indicating that the video power cable was indeed the issue. Prolonged usage: If the reversing camera still does not display after checking the above two scenarios, it may be due to the reversing camera being used for too long, resulting in poor chip photosensitivity. This not only causes a lot of snow-like interference but can also lead to a black screen in severe cases. It could also be due to defects in the vehicle's circuit design. However, issues like chip abnormalities and design defects are beyond the scope of self-repair and require inspection, repair, or direct replacement at a repair shop.
