What Are the Reasons for No Display on the Car Screen?
3 Answers
The reasons for no display on the car screen include defects in the central control system, USB port issues, etc. Specific details are as follows: Central Control System Defects: Due to incompatibility between the Bluetooth of certain brands and models of mobile phones, third-party software, and the host software, the central control screen may go black when connecting or playing songs. In such cases, the central control system usually returns to normal after a restart. Center Console USB Port Issues: Many users have reported that plugging anything into the center console USB port can cause the screen to go black. The solution is simple: just unplug the USB device. Power Circuit Issues: If this is the cause, the car owner can only take the vehicle to a 4S shop for inspection and repair, as circuit faults cannot be resolved on one's own.
Last time I drove, I noticed the screen went black, possibly due to a loose power connection. Sometimes the screen remains dark after starting the vehicle; check if a fuse has blown, which can be found in the fuse box. It could also be that the screen itself is faulty, with loose or aged wiring being a common issue, especially on bumpy roads. On the software side, a system crash may require a reboot—try turning the car off and on again or use the settings button on the steering wheel to reset. User error is another possibility, such as setting the brightness too low or the screen saver activating. Safety-wise, a non-functional screen affects navigation and reversing camera functions, so it's advisable to visit a professional repair shop immediately for inspection. Avoid disassembling it yourself to prevent short circuits.
As a parent who drives daily, when encountering a screen with no display, I first check for simple issues. It might be that the power isn't supplied—after starting the vehicle, the screen should light up. If it doesn't, check if the cigarette lighter plug or connection is loose. Software bugs are also common; the system may freeze, causing a black screen. Try holding down the center console button to reboot. Additionally, there could be hardware failure with the screen—panels can wear out over time. This affects the reverse assist function, which is especially dangerous in poor visibility conditions like rainy days. That's why I advise people not to delay repairs—safety comes first.
