What are the reasons for the car's central control screen not lighting up?

The reason why the car's central control screen does not light up may be due to poor line contact, aging of the power signal line, etc. Poor line contact: It is necessary to check whether the line is loose in time. If there is, it will naturally cause the central control screen to go black. At this time, just connect the loose part properly. Aging of the power signal line: It may also be because the power signal line is aging. You can try to replace it with a new one. If the black screen is solved, it means that there is indeed a problem with the power signal line. Excessive screen usage time: If you have checked whether the line is loose and whether the signal line is aging, and the central control screen still does not light up, it should be because the screen has been used for too long, causing the power supply module to fail, which not only causes lag but also a black screen in severe cases.
The central control screen in my car went black inexplicably last time, which was quite a hassle. The most likely cause is a blown fuse. Try replacing it with one of the same parameters in the fuse box—many car owners have encountered this issue. System crashes are also common, just like a phone freezing. Turning off the car and waiting a few minutes before restarting often resolves it. Wiring issues shouldn’t be overlooked either; loose connections or short circuits can cause voltage instability, especially when driving on bumpy roads. The screen itself could be damaged, particularly in older cars with prolonged use. Incorrect wiring during aftermarket audio installations or adding devices can also trigger this. A non-functional central control screen while driving affects music and navigation, which is frustrating. Safety first—after parking, check the fuse first. If that doesn’t work, take it to a professional for repair. Avoid tampering with the electrical system yourself to prevent further damage.
