What Causes the Black Screen on the Buick LaCrosse Center Console Display?

[Marley]

Buick LaCrosse center console display black screen is caused by poor contact between the host and the display connection. You can try re-plugging the data cable or replacing the data cable. For the vehicle's center console display, it operates after the car is started, with the brightness set to default and generally does not require adjustment. In the car's lighting control area, there is a switch to adjust the brightness of the center console display. Moving the scroll wheel up and down can adjust the brightness. The interior lighting of the center console automatically turns on when the headlights are activated, and its brightness can also be adjusted. However, if the center console display remains completely black and cannot be adjusted or restored, first turn off the car's engine, then disconnect the car's battery terminals to discharge and reset the car's control computer, and finally reconnect the power to try again. If the issue persists, timely repair is necessary.
