2 Answers
Beijing BJ40 central control screen black screen reasons include aging wiring, prolonged usage, and circuit design defects. Aging wiring: This may be due to the aging of the power signal line of the Beijing BJ40 central control screen. You can try replacing it with a new signal line. If the black screen issue is resolved, it indicates a problem with the power signal line. Prolonged usage of the central control screen: When the Beijing BJ40 screen is used for an extended period, it can cause the power supply module to malfunction, leading not only to lag but also to a black screen in severe cases. Circuit design defects: It is necessary to go to a repair shop for inspection, repair, or direct replacement. When the Beijing BJ40 central control screen shows a black screen, you can first check whether it is caused by overheating protection due to the installation of additional devices. If the check is normal, it is recommended to take the vehicle to a professional repair facility for further inspection and handling.
When I used to drive the Beijing BJ40, I also encountered the issue of the central control screen going black. The most common cause was a blown fuse, especially prone to failure on bumpy roads. Additionally, poor wiring connections are frequent, such as loose plugs or oxidation leading to power loss. On the software side, the system occasionally freezes, requiring a reboot or program update. It's recommended to regularly check the fuse box during maintenance and avoid using incorrect charging cables to minimize problems. If the screen goes black while driving safely, don't panic—handle it by pulling the handbrake.
