What to Do When the Car's Central Control Screen Goes Black?
3 Answers
Solutions for a black central control screen in a car are as follows: 1. If the central control screen goes black and does not light up, you can consider restarting the screen by turning the ignition on and off. If this does not resolve the issue, it is likely due to poor line contact. It is necessary to promptly check whether there is a loose connection in the wiring. If there is, it will naturally cause the central control screen not to light up. In this case, simply reconnect the loose parts properly. Of course, it could also be because the power signal line has aged. You can try replacing it with a new one. If the black screen issue is resolved, it indicates that the problem was indeed with the power signal line. 2. If after checking the above two situations the central control screen still remains black, it is probably due to prolonged use of the screen, causing a failure in the power supply module. This not only results in lag but, in severe cases, the black screen phenomenon we are discussing today. Of course, it could also be due to a defect in the circuit design. However, issues like module abnormalities and design defects are beyond our ability to fix and require inspection, repair, or direct replacement at a repair shop.
When encountering a black screen on the center console display, I always start with basic checks. First, confirm if the vehicle is ignited, as insufficient power supply often causes black screens. Next, attempt a forced system reboot: press and hold the center console power button for over 15 seconds - sometimes a system crash just needs a restart. If that fails, check the fuses: locate the fuse labeled for the infotainment system in the engine compartment or dashboard fuse box, and replace any blown fuse (costs about $0.50). If still unresolved, disconnect the battery negative terminal for five minutes then reconnect to reset electronic modules. Don't overlook software updates: download new firmware from the manufacturer's website and install via USB to patch bugs. Finally, for hardware issues like screen failure or loose wiring, avoid DIY disassembly (risk damaging wire harnesses) and visit a 4S shop for diagnostic trouble code scanning. I regularly clean screen connectors to prevent oxidation, which helps avoid black screens.
Last time my car's central control screen suddenly went black, which scared me so much that I immediately pulled over. First, try restarting the car: turn off the engine and wait a few minutes before starting it again, or hold down the central control switch to reboot the system. A simple way to check the fuse: open the car door and locate the fuse box position marked in the manual, replacing one costs just a few cents. I've experienced black screens caused by an aging battery with unstable voltage; use a multimeter to check the battery voltage, which should normally be around 12.5V. If these methods don't work, it might be a software freeze—disconnect the battery cables for half an hour and then reconnect them to reset. To save on repair costs, I often try DIY fixes first; if that doesn't work, I take it to a small repair shop to check if the connectors are loose. Sharing a little tip: parking the car under the sun can easily overheat the screen, so adding a sunshade in summer can help protect it.
