The reasons are as follows: 1. Power failure: the on-board display screen does not light up, which may be a power problem, the third-party software does not match the system, or the software version is too old, resulting in system failure, failure to display normally, and screen damage. 2. Line aging: the line is aging and causes black screen due to too long use time. If there is no image or sound, the power plug of the navigation display may be loose. If there is no sound or image directly, the DVD is broken.
3. Battery failure: It may be that the battery is seriously short of power, which causes the electrical equipment on the vehicle to be unable to operate normally. 4. Cable fault: if there is power, the black screen does not light up, it may be that the on-board navigation cable is damaged. With the long service time, many lines will show signs of aging.
The central control screen doesn't light up after the car battery loses power
The central control screen does not light up. We can try to re ignite it to restart the central control screen. The central control screen does not light up, which may be because the battery is dead. It may also be that the screen cable plug is loose, the power supply is not normal, or the screen cable is disconnected. If the battery is dead, we press the power button for 5 seconds, and the screen does not light up and the power indicator does not light up or goes out immediately after it lights up, it means the battery is dead.
If the flat cable plug of the display screen is loose, we can unplug the flat cable and plug it in again. If the display screen is broken, replace it with a longer one. The new display screen is OK. Sometimes the power is used to ignite when starting up. The voltage is low. Occasionally the display screen does not light up, which is normal. If it does not light up many times, check whether the power supply is abnormal, If the power supply is abnormal, the power supply module must be replaced. If the display panel cable is broken, it must be reconnected. Generally, we cannot do it by ourselves. We need to use a soldering iron to weld, and it is also easy to break again. It is easier to replace a new display directly.
