What's the reason for the car screen not lighting up?

The reasons why the car screen is not lighting up are: 1. Poor line contact; 2. Aging of the power signal line; 3. The screen has been used for too long, causing the power supply module to malfunction, not only resulting in lag but also severe black screen phenomenon; 4. There are defects in the circuit design. The car central control screen is a car appliance with a relatively high failure rate. After long-term use, the screen may experience lag or black screen. The solutions are as follows: 1. Reconnect the loose parts of the line properly; 2. Replace with a new power signal line; 3. Go to a repair shop for inspection and repair or directly replace the power supply module.
When my car screen suddenly went dark, I was startled and thought something serious had happened. First, I quickly checked the fuses, as a blown fuse is the most common point of failure. The fuse box is located inside the car, and its position is marked in the manual. If replacing the fuse doesn’t fix the issue, try rebooting the system: hold the power button for 10 seconds or disconnect the negative battery terminal for a few minutes before reconnecting. This can resolve software freezes. Sometimes, the screen brightness might have been accidentally turned down or off—just adjust it in the settings. If it’s a hardware issue, like a loose screen connection or a faulty screen itself, you’ll need to visit a professional repair shop. If the screen goes dark while driving, don’t panic—pull over safely to address the issue. Regular maintenance of the vehicle’s electrical system can prevent such failures, and avoiding prolonged exposure to high temperatures can protect the screen.
I enjoy tinkering with car electronics, and a non-responsive screen is often caused by software bugs. First, try forcing a reboot of the infotainment system by holding the power button until it restarts. Check for any available software updates, as outdated versions are prone to crashes. In the settings, ensure the brightness isn't turned down or the screen-off option isn't accidentally enabled. If the issue persists, it might be a hardware problem like a faulty backlight or loose connector. You can carefully open it up to inspect the wiring, but don't force anything to avoid damaging the circuits. Improperly installed audio or navigation systems can also cause conflicts, so try restoring factory settings. Always use your phone for navigation as a backup to avoid relying solely on the screen. High temperatures accelerate electronic component aging, so park in shaded areas when possible.
