Why is the car's display screen not lighting up?

[RachelRose]

The reasons why the car's display screen is not lighting up are as follows: 1. Poor line contact: It is necessary to promptly check whether there is a loose connection in the lines. 2. Signal line issue: The power signal line may have aged, and you can try replacing it with a new one. If the black screen issue is resolved, it indicates that the power signal line indeed has a problem. 3. Power supply module failure: Prolonged use of the screen may cause the power supply module to fail, resulting in a black screen phenomenon. 4. Circuit design defect: It is necessary to go to a repair shop for inspection and repair or direct replacement.

Last time I was driving, the display suddenly went dark, and I was so panicked! I had just left the parking lot, and the screen was pitch black—no navigation or music. I suspect a blown fuse because my car battery had been low on power before, and unstable voltage can easily melt fuses. Another possibility is a loose power cable or an unplugged connector. Or maybe the screen's motherboard is aging—my old car is ten years old, and electronics tend to fail over time. Software freezing is also an issue; sometimes restarting the infotainment system can fix it. But if it happens frequently, it's best to get it checked at a repair shop ASAP. Don’t tinker with it yourself—short circuits could make things worse. In short, regularly checking the electrical system and battery can prevent issues. Safety first!

The car's display screen going black is mainly caused by three common issues: power supply problems, hardware failures, and software bugs. For example, a blown fuse interrupting the power supply or low battery voltage causing insufficient power. On the hardware side, it could be a broken screen backlight or loose/disconnected wiring, especially on bumpy roads. Software freezes are much simpler to deal with—just try holding down the restart button to resolve it—I encountered this after a system update before. Don’t overlook environmental factors, as high temperatures or moisture can corrode circuits. It’s recommended to start troubleshooting from the fuse box, located near the glove compartment; if the issue persists, use a diagnostic tool to check error codes and replace parts promptly for peace of mind.

It's really annoying when the display doesn't light up, I've encountered it a few times. The most common cause is a system crash, which can usually be fixed by restarting the vehicle. If that doesn't work, check the fuse or battery condition. If simple troubleshooting doesn't help, then go to a professional repair shop to avoid wasting money. Also, make sure the connectors are properly plugged in to prevent issues.
