What Causes the Navigation Central Control Screen to Go Black?

[AthenaAnn]

It may be due to poor line contact, so it's necessary to promptly check whether there is a loose connection in the circuit. A loose connection naturally leads to a black screen on the central control display, and the issue can be resolved by properly reconnecting the loose parts. It could also be caused by aging of the power signal line. Trying to replace it with a new one might solve the black screen problem, indicating that the power signal line was indeed faulty. Other reasons for the navigation central control screen going black include: 1. Prolonged Use: If after checking for loose connections and aging signal lines the central control screen still doesn't light up, it's likely due to prolonged use causing a failure in the power supply module. This not only results in lag but can also lead to a black screen in severe cases. 2. Design Flaws: It may also be caused by defects in the circuit design. Issues like module abnormalities and design flaws are beyond the scope of DIY fixes and require inspection, repair, or replacement at a repair shop.
