The reasons for the car display screen not lighting up: 1. The DVD encountered a lag during operation, causing the car display screen not to light up. Restart the power of the car display screen; 2. The screen is broken or there is an issue with the wiring, or the system crashed due to IC and motherboard problems. In this case, you can only drive to a 4S store for maintenance or go to a repair shop for inspection; 3. The software version has not been updated in time or the version is outdated. Simply upgrade the software version. The car display screen not only provides information such as navigation, reverse camera images, and vehicle fuel consumption for viewing, but also offers numerous multimedia entertainment systems for operation, providing convenience to the occupants while enhancing the interior aesthetics. Once the car display screen malfunctions, it will cause inconvenience to the driver, so if there are any issues, they should be checked and repaired promptly.
Having driven for over a decade, when the display doesn't light up, you should start troubleshooting from the source. The most common issue is a blown fuse—check the fuse box near the instrument panel to see if the corresponding fuse is intact. Another possibility is a loose power cable; bumpy roads can cause connectors to come loose, so make sure to reconnect them firmly. Display hardware failures are also quite common, especially in older vehicles where prolonged use leads to aging and failure. If the screen returns to normal after ignition when the battery is low, it's a sign to check the battery health and charging system. Software glitches are frequent in modern cars—try restarting the vehicle or performing a system reset. For safety, a black screen while driving can be distracting, so it's wiser to pull over promptly. To prevent such issues, having technicians test the electronic display functionality during regular maintenance is crucial.
As an automotive tech enthusiast, I've found that unlit displays are often caused by software bugs or system crashes. A simple vehicle restart usually resolves the issue. Certain models have specific reset button combinations - try following the manual instructions. Sometimes the display function might be accidentally turned off in system settings. Wiring issues shouldn't be overlooked either, especially power line shorts or interference after modifications. Blown fuses are common; simply purchase and replace with identical specifications from stores. Compatibility problems after software updates may cause black screens - maintaining the latest version helps prevent this. Don't worry about it being too difficult; YouTube offers many DIY tutorials for preliminary troubleshooting, practical and convenient. Developing the habit of checking battery status is equally important.
