What Causes the Black Screen of Car Navigation System?
2 Answers
Here are the specific reasons for the black screen of the car navigation system: 1. Poor line contact: It is necessary to check whether there is a loose connection in the line. Just reconnect the loose part properly. 2. Aging of the power signal line: You can try replacing the power signal line. 3. The screen has been used for too long: This may cause a failure in the power supply module. It is recommended to go to a 4S store for inspection or replacement of the power supply module. 4. Defects in circuit design: You need to go to a repair shop for inspection and repair or simply replace it. If it is under warranty, go for warranty service; if not, go to a 4S store for inspection and repair.
I just encountered an issue with my car's navigation screen going black and tried troubleshooting it myself. There are quite a few reasons why the navigation screen might not light up. Simply put, it could be due to loose or poor contact with the screen's power cable—my car's screen once disconnected after driving on a bumpy road. Another possibility is system freeze, requiring a restart; just like when a phone freezes, pressing the reset button can restore functionality. Blown fuses are also common, especially in older cars prone to circuit issues. Software conflicts or virus infections can also cause the screen to go black, so it's important to regularly update map data. Poor heat dissipation is another critical factor; the navigation system may automatically shut down when overheating under high temperatures. My advice is to first check the connections and try restarting. If that doesn't solve the problem, take it to a repair shop immediately to check the wiring and system—don't delay and risk being without navigation.
