What Causes the Car's Central Control Display Screen Not to Light Up?
1 Answers
The reasons why the car's central control display does not light up are as follows: 1. The central control screen system is frozen. Abnormal operation of system components due to high or low temperatures can cause this situation. It will recover when the vehicle temperature becomes suitable. 2. After starting the vehicle, the central control is considered to be turned off. At this time, just press the power button to turn it on. 3. The fuse of the vehicle's central control screen is broken. Without a power supply, it will not light up. Replace the fuse in the engine compartment fuse box. Solutions: 1. First, check whether the power supply of the display screen is normal. If the power supply is abnormal, replace the power supply module. 2. Then check whether the contact of the cable is good. If there is a problem, replace the cable. 3. Check whether the display screen is damaged. Replace the display screen for testing. If it returns to normal, the display screen is damaged. If it is the same, the power supply is normal, and the cable contact is good, check whether the mainboard video output is normal.
