What are the reasons for the car display screen not lighting up?

The reasons for the car display screen not lighting up are: 1. Abnormal power supply to the display screen; 2. Damage to the car display screen; 3. The car display system has crashed due to some reason; 4. Faults in the car display screen's wiring, IC, or motherboard. The owner can try restarting the car display system to see if it resolves the issue. If not, they can go to a repair shop for inspection and repair. There are two types of car display screens: one is a television placed in passenger vehicles for viewing, essentially a car TV, and the other is a small-sized car display monitor. Car displays can receive car audio-visual signals and play them back on the screen, while also being usable on similar moving vehicles, making them convenient for use during vehicle movement.
When the car display screen doesn't light up, it's often due to a blown fuse first, probably caused by an overload of the vehicle's electrical devices. Just like during my last long-distance drive, the first step is to check the fuse box, located under the driver's seat. If the fuse is fine, then inspect the wiring connections—maybe a plug has come loose or been chewed by rodents. Try re-plugging it tightly in such cases. The display screen itself might also be aging or damaged, especially in older cars. Safety is paramount; a non-functional display can mess up navigation and easily lead to accidents. During regular maintenance, I always have technicians check the wiring. Alternatively, low battery charge causing voltage instability could be the culprit—try restarting the vehicle to see if it recovers. Don't underestimate this issue; get it checked at a repair shop as soon as possible to avoid greater driving risks. Last time, I delayed too long and ended up spending unnecessary extra money.
When you play around with cars a lot, it's common to encounter issues like the display screen not lighting up. I suspect the power supply is the primary culprit, such as a blown fuse or a dead battery causing insufficient voltage. Poor cable connections are also frequent problems, like loose plugs or disconnections due to bumps—a quick test is to tap the center console. Hardware failures, like a burnt-out screen, require replacement, or control module issues affecting signal transmission. From a safety perspective, a blacked-out display affects the rearview camera and warning alerts, which is quite dangerous. I recommend safely parking first to troubleshoot. Software bugs can also cause trouble—try restarting the system or updating the firmware. Avoid DIY disassembly; it's easier to let a professional shop handle repairs and prevent messing up other components. In short, rule out multiple factors to ensure driving safety is the top priority.
