What are the reasons for the black screen with no display on the Haval H6?

Haval H6 screen black screen with no display reasons are as follows: Poor line contact: The phenomenon of a black screen on the car's central control screen is most likely due to poor line contact. It is necessary to promptly check whether there is a loose connection in the lines. If there is, it will naturally lead to a black screen on the central control screen. In this case, simply reconnect the loose part properly. Aging of the power signal line: Of course, it could also be due to aging of the power signal line. You can try replacing it with a new one. If the black screen issue is resolved, it indicates that the power signal line is indeed the problem. Failure of the power supply module: It may be due to prolonged use of the screen, leading to a failure in the power supply module, which not only causes lag but also severe cases of black screen. Of course, it could also be due to a defect in the circuit design, which requires inspection, repair, or direct replacement at a repair shop.
I've been driving a Haval H6 for many years, and when encountering a black screen, the most common causes are a blown fuse or a loose power connector. You can open the vehicle's front hood and locate the corresponding fuse in the fuse box, usually labeled for the infotainment system or navigation. Use a test light or multimeter to check if it's intact. If the fuse is fine, check if the screen backlight has failed or if the vehicle's vibration has caused a loose wire connector—try gently pressing the plug to secure it. Sometimes, it's just a software freeze; simply turning the vehicle off and restarting it a couple of times might restore the screen system. Additionally, the Haval H6's screen relies on signals from the vehicle's ECU, and unstable voltage, such as from an aging battery, can also trigger a black screen. Regular maintenance of the electrical system can help reduce such issues. If all else fails, don't force it—safely drive to a repair shop for a detailed check.
I was really panicked when my Haval H6's screen went black last time, leaving the navigation completely unresponsive on the road. Reflecting on my daily usage, I realized it might have been caused by an overly powerful cigarette lighter charger causing a short circuit and blowing a fuse. After parking, I checked the fuse box, replaced the fuse, and the issue was resolved. My advice is to start with the simplest solutions: turn off the car, wait a few minutes, and restart it. If that doesn’t work, check the fuse locations, referring to the manual for the infotainment module section. Don’t rush to dismantle the screen—you might end up damaging the wiring and making things worse. Also, pay attention to your vehicle’s environment, like avoiding prolonged exposure to sunlight that could overheat the screen and cause it to freeze. When parking, try to turn off the screen to save power. Finally, take it to a repair shop for a full diagnostic scan of both software and hardware. Usually, spending a bit of money can get it fixed without much hassle.
