1 Answers
The reasons for the display screen in the Geely Emgrand car not lighting up include power supply issues, poor contact of the wiring harness, or a damaged display screen. Here are the specific solutions: 1. Power supply issues: First, check if the power supply to the display screen is normal. If the power supply is abnormal, replace the power supply module. 2. Poor contact of the wiring harness: Check if the wiring harness contact is good. If there is a problem, replace the wiring harness promptly. 3. Damaged display screen: Check if the display screen is damaged. Replace the display screen for testing. If it returns to normal, then the display screen is damaged. If the problem persists, with normal power supply and good wiring harness contact, check the video output signal of the motherboard and replace the motherboard for further testing.
