What is the reason for the non-responsive display screen of the Great Wall Haval H6?

The reasons for the non-responsive display screen of the Great Wall Haval H6 are: 1. Display screen malfunction; 2. Poor line contact; 3. Module circuit failure; 4. Loose power plug of the navigation display. The Great Wall Haval H6 is a compact SUV with body dimensions of: length 4653mm, width 1886mm, height 1730mm, and a wheelbase of 2738mm. The Great Wall Haval H6 is equipped with a 2.0T turbocharged engine, with a maximum power of 155kW, a maximum power speed of 6000 to 6300 rpm, a maximum torque of 325Nm, and a maximum torque speed of 1500 to 4000 rpm.

I think it's quite common for the Great Wall Haval H6 display screen to be unresponsive. It might be a blown fuse. I encountered this once while driving. Check the corresponding fuse in the engine compartment's fuse box to see if it's blackened or melted, and replace it with a new one if necessary. Power issues like low car battery voltage can also cause the screen to fail to start. Use a multimeter to measure the voltage; if it's below 12 volts, charge or replace the battery. A software system crash is another possible reason. Try holding down the restart button on the car key or turning off the ignition switch for a few minutes before restarting. Loose wiring connections often occur in older cars. Open the panel to check if the plugs are loose or corroded. If the screen hardware is damaged, such as a failed backlight or a broken touchscreen, you'll need to go to a 4S shop to replace the part. Keeping the car clean and avoiding frequent exposure to direct sunlight can help prevent issues, making driving more worry-free.

When using my Haval H6, the display suddenly went black once, and troubleshooting was quite simple. First, check if the vehicle's power switch is functioning normally. If the engine won't start, it might be a battery issue affecting the screen. Try resetting the multimedia system by holding the power button for ten seconds and then restarting—this can recover from software updates or crashes. Check the fuse box, especially if a fuse is blown; just replace it, as they're very cheap. The screen is prone to malfunction in high temperatures—I encountered this in summer, and parking in the shade to let it cool down fixed it. Loose connections, like a plug coming undone, can be fixed by securing them. If that doesn’t work, inspect the central control module; if it fails, the entire system can crash, requiring professional repair. During regular use, avoid excessive bumps or vibrations to the screen, and maintain the battery charge periodically to prevent issues.

When encountering a non-functional display screen in the Haval H6, I prioritize safety as it shows speed and warning lights. A black screen obstructs crucial information and increases accident risks, so I immediately pulled over to inspect. Potential causes include a blown fuse—locate and check the corresponding marked one in the fuse box for replacement. If it's a software freeze, restarting the vehicle system may resolve it. Hardware failures like screen backlight issues or aged/wiring short circuits require professional diagnosis. It's advisable to visit an authorized repair shop promptly; avoid DIY disassembly to prevent further damage. Keeping vehicle software updated can reduce failure rates—drivers should stay mindful of this.
