Methods to deal with a black screen on the car's central control display: 1. Check if the host power supply is properly connected and whether the voltage is stable; 2. Inspect whether the data cable connector of the display is in good contact with the signal output interface of the graphics card; 3. The car's infotainment module may fail, as the numerous electronic products inside the car can cause interference between internal modules, leading to a black screen on the display. The car's central control is the area that manages comfort and entertainment devices such as the car's air conditioning and audio system. It includes the central locking system, central console, audio control panel, and more. Functions of the car's central control: 1. The central locking actuator can execute the driver's commands to lock or unlock the doors; 2. It controls adjustments for memory seats, music system settings, entertainment system settings, roof camera functions, automatic parking, and other features.
I've encountered this situation several times, and usually start troubleshooting from the simplest steps. First, try restarting the car - turn it off, wait a few minutes, then start it again. Sometimes system freezes can be resolved this way. If the screen remains black, check if the corresponding fuse in the fuse box has blown. The location is marked in the user manual - pull it out to check if the metal wire is intact. Wiring issues are also common - try gently shaking the wire harness connectors near the center console to see if the screen flickers. Once when I was cleaning dust near the air vents, I discovered it was caused by a loose connector. Of course, software crashes can also make the display stop working - remember to regularly update the vehicle's system. If you really can't fix it, just go directly to the 4S shop. They have diagnostic tools to read fault codes for professional repairs - don't randomly disassemble things yourself to avoid damaging components.
Friends with strong hands-on skills can try to solve the black screen issue themselves. Last week, my car had the same problem. First, I held down the power button for ten seconds to force a reboot of the head unit. If the screen lit up, it indicated a software glitch. If that didn’t work, I opened the glove compartment to locate the fuse box and replaced the corresponding numbered spare fuse. Also, check if the power and video cables are securely plugged in. If the connectors are oxidized, spray them with electronic cleaner. If you’ve installed an aftermarket reverse camera, inspect the wiring for potential shorts—I once burned a fuse due to faulty wiring when installing a dash cam. If the screen remains completely unresponsive, consider a possible failure in the head unit module, especially in older cars where capacitors are prone to aging and leakage. If these DIY fixes don’t work, a repair shop can usually resolve it in half an hour at a much lower cost than a dealership.
