What causes the central control screen of the 14th-generation Sylphy to go black?

14th-generation Sylphy display screen black screen is most likely due to poor line contact, and it is necessary to check whether there is a virtual connection in the line in time. It may also be because the power signal line is aging, you can try to replace a new one, if the black screen is resolved, it means that the power signal line is indeed a problem. The following are other reasons: 1. Power supply module failure: If after checking the above two situations, the central control screen is still black, it should be because the screen has been used for too long, resulting in the power supply module failure, not only there is a lag, but also a serious black screen phenomenon. Of course, it may also be due to a defect in the circuit design. But problems such as module abnormalities and design defects require inspection and repair at a repair shop or direct replacement. 2. Program instability: The black screen of the display screen may also be caused by the instability of the internal program of the display screen. In such a situation, it is necessary to delete some unused software or programs and clear the system memory. If it is due to internal line problems, such a situation requires checking the problem of the cable, or it may be that the motherboard is damaged, which affects the black screen. These fault problems are basically more common phenomena.
Last time I was driving the 14th-generation Sylphy, the central control screen went black, which really stressed me out. Usually, the causes are a blown fuse or a hardware failure in the screen. A simple restart of the infotainment system can temporarily fix the issue. However, deeper issues might include insufficient battery power or loose plugs causing poor contact, especially if the wiring gets jostled loose on bumpy roads. Some friends have also encountered system crashes due to incomplete software updates before startup, requiring a reset with specialized tools. Long-term, dust buildup on internal circuits can also cause malfunctions. I recommend first checking the corresponding fuse in the fuse box—typically a 10A one—and if it's intact, then inspecting the wiring harness for aging. Regular cleaning of the screen interface during routine car use can significantly reduce the chances of a black screen. If all else fails, a professional inspection of the module or a screen replacement at the dealership may be necessary.
