What Causes the Black Screen on Car Central Control Display?
2 Answers
If the central control display in your car shows a black screen, it may be due to poor line contact. It is necessary to promptly check whether there is a loose connection in the wiring. Other reasons for the black screen on the central control display include: 1. Aging wiring: 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 problem indeed lies with the power signal line. 2. Prolonged usage: Extended use of the screen can lead to failures in the power supply module, resulting not only in lag but also, in severe cases, a black screen. Of course, it could also be due to defects in the circuit design. However, issues like module abnormalities and design defects are beyond the scope of self-repair and require inspection, repair, or replacement at a repair shop.
When driving, the central control screen occasionally goes black. I've encountered this several times before. Common reasons include a blown fuse, which acts like a small circuit breaker—melting when the current is too high to protect the circuit. You can try replacing the corresponding fuse in the fuse box. It might also be a software glitch where the system freezes and becomes unresponsive, similar to a smartphone crashing. Restarting the car's power usually fixes this. Another possibility is poor wiring connections, such as loose plugs or aged wires making poor contact. Also, high temperatures can trigger the screen's overheating protection, causing it to shut down automatically. Don't panic if this happens—first, try turning off the engine for a few minutes and then restarting. If that doesn't work, check the fuse box to see if the indicator light is on. As a temporary solution, you can use your phone for navigation. To prevent such issues, avoid leaving the car exposed to direct sunlight for too long and have the central control system checked during regular maintenance to catch minor problems early.
