2 Answers
The reasons for a car display screen going black are: 1. The car's power voltage is unstable; 2. There is an issue with the cable on the back of the central control display screen. The solutions for a black car display screen are: 1. Check if the main power supply is properly connected and if the voltage is stable; 2. Check if the data cable connector of the display is in good contact with the signal output interface of the graphics card; 3. Check if the car module has failed. The car display screen includes the central control door lock system, central console, and audio control panel, and its functions are: 1. The central lock actuator can be used to execute the driver's instructions to lock or unlock the door locks; 2. Control the adjustment of memory seats, music system adjustments, entertainment system adjustments, roof camera function, and automatic parking function.
As a seasoned driver with ten years of experience, I've encountered several instances of display screen blackouts, and the reasons are quite varied. The most common cause is a blown fuse, where the circuit protection automatically cuts off the power. Software crashes are also a frequent issue, such as when a system update fails or the memory is full and can't handle operations—simply restarting usually fixes it. Poor cable connections are another culprit; loose or oxidized connectors to the screen can interrupt signals, sometimes noticeable with just a slight touch. Hardware aging is also common, especially in high-temperature environments where the screen board is prone to burning out. The key is to stay safe—don't panic if the screen goes black, pull over safely, and try restarting it. If the problem persists, it's best to visit a repair shop for a professional diagnosis to avoid affecting navigation and rearview monitoring functions.
