What are the reasons for a black screen on the car navigation display?
1 Answers
There are several reasons for a black screen on the car navigation display, including the vehicle's power supply voltage, navigation system cables, and the power connector of the navigation display. Below are detailed explanations of the specific causes: 1. Vehicle power supply voltage issues: Check the stability of the vehicle's power supply voltage to rule out voltage fluctuations. 2. Navigation system cables: If the voltage is stable, inspect the cables on the back of the device for any issues. Try replacing the connections to troubleshoot. If the connections are fine, check the display cables of the device. If there's a problem, replace them with new ones for testing. 3. Loose power connector of the navigation display: If there's only no image but sound is present, it indicates a loose power connector of the navigation display. If there's no sound or image at all, the issue likely lies with the DVD system.
