What is the reason for the navigation screen of Haval H6 not lighting up?

The reason why the navigation screen of Haval H6 does not light up is the instability of the power supply voltage. The following is a related introduction about the Haval H6: 1. Version types of Haval H6: Haval H6 is the main model under the Haval brand. On August 25, 2011, the Haval H6, positioned as an urban intelligent SUV, was grandly launched at the Great Wall Motors Tianjin new factory, offering Mitsubishi 2.0L gasoline-powered models and Green Jing 2.0T diesel models, divided into three versions: urban, elite, and luxury. 2. Power of Haval H6: Haval H6 is equipped with the "China Top Ten Engines" 1.5T direct injection turbo engine, adopting the same CVVL continuous variable valve lift technology as BMW, which is leading in its class. The turbo intervenes at 1000 rpm, providing more power at low speeds, with a maximum power of 124kW and a peak torque of 285N·m, delivering stronger performance.
As an experienced automotive systems enthusiast, I believe there could be several reasons why the Haval H6's navigation screen isn't lighting up, including a blown power fuse, software crash, or hardware aging. The fuse box is located under the driver's seat, and the relevant 10A fuse is prone to blowing due to overload; simply check and replace it. Software issues are common—try restarting the system: turn off the engine, exit the vehicle, wait 5 minutes, and then restart. If that doesn't work, consider loose wiring connections or a failed screen backlight; bumpy road conditions can cause plugs to come loose. The screen itself may overheat and malfunction after prolonged use, especially during high summer temperatures. I recommend first using an OBD diagnostic tool to check the voltage and confirm it's not a generator issue. Visit a 4S shop for timely repairs, and avoid disassembling components yourself to prevent damage to other parts—safety first.
As an owner of the Haval H6, I once encountered a black screen issue with the navigation display. The screen suddenly went dark, and I initially thought it was a major malfunction, but it turned out to be a software freeze; pressing and holding the navigation power button for 10 seconds to reboot resolved the problem. The technician mentioned that system updates often introduce bugs, so it's advisable to check for any new firmware available for download. If the black screen persists, it could be due to a blown fuse or a loose USB connection; the Haval's interface at the rear of the screen is prone to becoming dislodged due to vibrations. Pay attention to environmental factors, such as parking in high-temperature areas, which can accelerate the aging of electronic components—I now use a reflective cover after parking for protection. Don't panic; first, try simple troubleshooting steps, and before heading to the repair shop, double-check the battery's condition; low voltage can cause screen instability.
