What is the reason for the non-illumination of the Haval H6 navigation screen?

If it occurs occasionally, it is normal because during engine start-up, most of the electrical power is used for ignition, resulting in relatively low voltage. If the screen fails to illuminate multiple times during start-up, you should check whether the power supply to the display screen is normal. If the power supply is abnormal, replace the power supply module. Then, check whether the connection of the wiring harness is good. If there is a problem, replace the wiring harness. Here is some additional information: Car center console: The car center console is the area that controls comfort and entertainment devices such as the car air conditioning and audio system. The car center console includes the central control door lock system, allowing the driver to control the opening and closing of all vehicle doors and the window lifting system through the car center console.
