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

The reasons for a car's display screen not lighting up are: 1. Loose or detached wiring ports; 2. Compatibility issues with the navigation system's software. A car display is a specialized monitor installed inside the vehicle, typically mounted on the headrest of the seat, also known as a headrest display. The car display is an essential component of the vehicle's audio-visual system, capable of receiving in-car audio-visual signals and playing them back on the screen. It is designed for use in automobiles and similar moving vehicles, providing convenience during operation. When connected to an onboard camera, it can automatically display the rear view while reversing, aiding in parking. Additionally, it may feature automatic backlight adjustment, anti-glare, and automatic angle adjustment functions to accommodate the specific needs of automotive use.
I remember my car had the same issue last month—the center console screen stayed completely black after startup. First, I checked the fuses in the small compartment to the left of the steering wheel and found the multimedia one was blown. Replacing it with a spare fuse fixed the problem immediately. Later, I realized it was caused by a cheap charger I plugged into the cigarette lighter, which short-circuited the wiring. I suggest you first check the fuse box manual to locate and inspect the corresponding fuse. If the fuse is intact, try holding the power button for ten seconds to force a system reboot—this trick works wonders for touchscreen freezes. Always have aftermarket devices installed at reputable shops; messy wiring can lead to all sorts of bizarre malfunctions.
