What Causes the Car Multimedia Screen to Go Black?
2 Answers
The phenomenon of a black screen is mostly caused by poor line contact, so it is necessary to promptly check whether there is a loose connection in the lines. Due to overheating of the central control screen: This is generally caused by the installation of additional equipment, such as navigation modules, reversing cameras, etc. The workload of the central control screen exceeds its design parameters, triggering the overheating protection function. In this case, the issue can be resolved by disconnecting the additional equipment or reasonably increasing the heat dissipation capacity. Due to loose power or grounding lines of the central control screen: This often occurs after the central control screen has been disassembled or additional equipment has been installed, altering the original car lines.
Last time my car's infotainment screen suddenly went black, and after struggling for a while, I found out it was a blown fuse. It's in that small box under the left side of the steering wheel—you can change it yourself with a pair of needle-nose pliers. If the screen is completely unresponsive, nine times out of ten, it's a fuse issue. If the screen occasionally flickers or the touch function fails, it's probably due to the infotainment system overheating or freezing. In that case, turn off the engine, lock the car, wait ten minutes, and then restart it—just like rebooting a phone. Remember to always plug in a power bank before a system update; if the power cuts out during the update, the whole module will need to be sent back to the factory for repair. If that doesn’t work, check the connectors for the camera and radar. Last time, when I installed a dash cam, I accidentally loosened the reverse camera cable, and the screen just stopped working.
