What causes the central control screen of the eighth-generation Accord to not light up?

[OBeau]

The reasons for the black screen issue on the central control screen of the eighth-generation Accord are as follows: Poor line contact: You can first restart the screen by turning the ignition on again. If the problem persists, it is likely due to poor line contact, and it is necessary to promptly check if there is any loose connection in the wiring. In this case, simply reconnecting the loose part properly should resolve the issue. Aging signal cable: Of course, if the power signal cable has aged, you can try replacing it with a new one. If the black screen issue is resolved, it confirms that the power signal cable was indeed the problem. Power supply module failure: If the above two scenarios have been checked and the central control screen still remains black, it is likely due to prolonged usage of the screen, causing a failure in the power supply module. Of course, this could also be due to a design flaw in the circuit. However, issues like module abnormalities and design flaws require inspection, repair, or direct replacement at a repair shop.
