Why does the display screen remain on after removing the car key?

[Douglas]

There are two main reasons for this issue: first, the key switch may be faulty, causing the vehicle to remain in the power-on position without completely turning off the electrical appliances. Second, the power supply of the central control screen may be malfunctioning, preventing it from automatically shutting off. More relevant information is as follows: 1. Damaged central control screen power supply: If the central control screen does not turn off, it might be due to a damaged power supply, which requires immediate attention. Otherwise, the vehicle may fail to start the next day due to battery drain. 2. Five numeric dots appear on the central control screen: These dots are actually part of the screen calibration process and do not indicate damage to the vehicle. After prolonged use, the touch points on the screen may become less responsive, prompting the system to automatically display a "Screen Calibration" page. Simply tap the five dots on the screen in order, and the system will automatically calibrate the screen. After calibration, the touch points will return to normal. If the central control screen becomes unresponsive, you can also manually enter the screen calibration program to correct it.
