How to restart the central control screen of Buick GL8?

[VanElliot]

The method to restart the central control screen of Buick GL8 is as follows: 1. If the central control screen goes black and does not light up, you can first try restarting the screen by turning the ignition on and off. If the screen remains black, it is likely due to poor line contact, so it is necessary to promptly check whether there is a loose connection in the wiring. 2. If there is a loose connection, it will naturally cause the central control screen not to light up. In this case, simply reconnect the loose part properly. Of course, it could also be due to aging of the power signal line, so you can try replacing it with a new one. 3. If the central control screen still remains black, it may be because the screen has been used for too long, causing a failure in the power supply module and resulting in lag. It could also be due to a design flaw in the circuit. For issues like abnormal modules or design flaws, it is necessary to go to a repair shop for inspection and repair or direct replacement.
