What are the reasons for the car's central control screen not lighting up?

[EthanLynn]

There are several reasons why the car's central control screen may not light up: Power supply to the display: First, check if the power supply to the display is normal. If the power supply is abnormal, replace the power supply module. Cable connection: Then, check if the cable connection is secure. If there is an issue, it will naturally cause the central control screen to go black. In this case, simply reconnect the loose parts properly. Display damage: Check if the display is damaged. Test by replacing the display. If it returns to normal, the display is damaged. If the issue persists, with normal power supply and secure cable connections, check the video output signal of the motherboard and test by replacing the motherboard.
