Why doesn't the screen display when it's cold?

Sylphy won't be cold, so the car display won't show. If your screen doesn't show, it is likely to be the following situations. It is recommended to check in turn. If the line is in poor contact, check whether there is any virtual connection on the line in time. If there is, it will naturally lead to a black screen in the central control screen. At this time, the virtual connection part is connected intact. Of course, because the power signal line is aging, you can try replacing it with a new one. If the black screen is solved, it means that there is something wrong with the power signal line. The central control panel of an automobile can be said to be an on-board electrical appliance with a high failure rate. It may get stuck if it is used for a long time.
