What does it mean when the reversing video shows no signal?

[Sylvia]

It may be due to unstable voltage or poor contact in certain circuits. Here are the reasons why the reversing image displays no signal: 1. Most reversing cameras have a switch that automatically turns on when the reverse gear is engaged. If there is no response from the reversing camera system after shifting into reverse, the problem may lie with the reversing camera switch. If there is no signal from the reversing camera and the central control screen goes black after shifting into reverse, it may be caused by poor contact in certain circuits. 2. The lack of signal from the reversing camera may be due to unstable voltage, a phenomenon often seen in aftermarket reversing cameras. Reversing cameras and parking sensors have almost become standard configurations in vehicles, as they help drivers accurately judge the distance to obstacles behind them. If the reversing camera has such issues, immediate repairs are necessary. Problems during the installation of aftermarket reversing cameras can lead to poor contact in certain parts, so it is best to seek professional help and reputable installers before installation.
