How to Fix a Black Screen on Honda Civic Dashboard?

[VanViolet]

If the central control screen of a Honda Civic displays a black screen and fails to light up, you can try restarting the screen or checking the wiring. If the issue cannot be resolved on your own, it should be promptly taken to a 4S shop for repair. Additional information is as follows: 1. Poor wiring contact: It is necessary to promptly check whether there is a loose connection in the wiring. In this case, simply reconnecting the loose part properly may solve the issue. It could also be due to aging of the power signal cable, in which case trying to replace it might help. 2. Other causes: Prolonged use of the screen may lead to a failure in the power supply module, resulting not only in lag but also in severe cases, a black screen. Additionally, it might be due to a defect in the circuit design, which would require inspection and repair at a service center or direct replacement.
