If the navigation display screen of Haval H6 is not lighting up, first check the stability of the car's power voltage to rule out the possibility of voltage instability. Stable voltage
As an experienced driver, I've encountered similar situations. When the center console screen of a Haval H6 goes black, first check if you accidentally touched the switch next to the volume knob – it can directly turn off the screen. If the screen doesn't light up at all after powering on, there's an 80% chance it's a blown fuse or wiring issue. Last time this happened in my car, it turned out the center console fuse was blown due to messy wiring during dashcam installation. Another common issue is software glitches – try holding the power button for ten seconds to force restart the system. If that doesn't work, you might need to check the ribbon cable connection behind the display, but this delicate work is best left to professionals as DIY disassembly can easily break the clips. By the way, if the screen suddenly goes black during night driving, don't panic – turn on hazard lights, pull over safely, then deal with the issue.
I've been driving the H6 for over two years, and the sudden blackout of the central control screen can indeed be alarming. Don't panic just yet—it might simply be because you didn't exit the navigation app before turning off the car, as certain programs freezing can cause the screen to go black. Try restarting the system by simultaneously pressing the menu button on the steering wheel and the volume knob. If there's no response, check the fuse box under the driver's side dashboard; fuses F21 and F28 are specifically responsible for the central control power supply. If everything seems normal, it's likely either a faulty display screen or a main unit issue—in such cases, visiting a 4S dealership for a computer diagnostic is the safest approach. Also, remember to regularly clean the central control's ventilation vents, as dust buildup can block airflow and cause the circuit board to overheat and fail. When installing aftermarket reversing cameras, avoid splicing wires, as this can easily lead to short circuits.
