Why is the car's display screen not lighting up?
1 Answers
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.
