What are the reasons for the black screen on the Cadillac CT6's central control?

[VanKennedy]

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 this does not resolve the issue, it is likely due to poor contact in the wiring, and you should promptly check for any loose connections. Other reasons for a black central control screen include: 1. Aging wiring: The power signal cable may have aged. Try replacing it with a new one. If the black screen issue is resolved, it confirms that the power signal cable was the problem. 2. Prolonged use: Extended use of the screen can cause the power supply module to malfunction, leading not only to lag but also to a black screen in severe cases. It could also be due to defects in the circuit design. However, issues like module abnormalities or design defects are beyond the scope of self-repair and require inspection, repair, or replacement at a service center.
