The reasons why the car's display screen is not lighting up are as follows: 1. Poor line contact: It is necessary to promptly check whether there is a loose connection in the lines. 2. Signal line issue: The power signal line may have aged, and you can try replacing it with a new one. If the black screen issue is resolved, it indicates that the power signal line indeed has a problem. 3. Power supply module failure: Prolonged use of the screen may cause the power supply module to fail, resulting in a black screen phenomenon. 4. Circuit design defect: It is necessary to go to a repair shop for inspection and repair or direct replacement.

Why is the Erguang Expressway notorious?

The specific main reasons why the Erguang Expressway is notorious are as follows. Due to unreasonable speed limits: At the 2600-kilometer mark of the Erguang Expressway, there is a speed limit sign restricting the speed to 100 kilometers per hour. Immediately behind the 100 km/h speed limit sign is a dedicated speed detection device. Many drivers, unable to reduce their speed in time after seeing the speed limit sign, get caught by the camera and receive speeding tickets. Because of this reason alone, over 80,000 drivers receive speeding tickets annually on this stretch of road. Unreasonable road signs and electronic surveillance: Another trap lies 2 kilometers and 600 meters away from Guangzhou. The road signs and electronic surveillance here are also unreasonable, with this single electronic surveillance capturing over 110,000 violations annually.
