What are the reasons for the central control screen of a Volkswagen car not lighting up?

[LeGideon]

There are several reasons why the central control screen of a Volkswagen may not light up, including poor line contact, aging power signal lines, and module abnormalities. Poor line contact: It is necessary to promptly check whether there is a loose connection in the lines. If there is, it will naturally cause the central control screen not to light up. Simply reconnect the loose part properly. Aging power signal lines: You can try replacing them with new ones. If the black screen issue is resolved, it indicates that the problem indeed lies with the power signal lines. Module abnormalities and design defects: Prolonged use of the screen may cause the power supply module to malfunction, leading not only to lag but also severe black screen issues. It could also be due to circuit design defects. However, problems like module abnormalities and design defects require inspection, repair, or direct replacement at a repair shop.
