If the vehicle display screen is not displayed, first check whether all functions are not displayed or some functions are displayed. If some functions can still be displayed, it may be a system problem, or a problem that the functional system module cannot be displayed, which needs to be solved by replacing the module or refreshing the system. If the whole display screen is not displayed, first check whether the wiring socket behind the display screen is loose or disconnected. Need to check the fuse in the fuse box. The monitor itself needs to be replaced because of its own failure. The failure of vehicle display screen may be due to power supply problems, mismatch between third-party software and the system, or outdated software version, resulting in system failure, abnormal display and screen damage.
Sometimes the problem of failure may be that the line is aging due to too long use time, which leads to failure. If there are only images and sounds, it may be that the power plug-in of the navigation display is loose; If there is no sound or image directly, the DVD should be broken. It may be that the battery is seriously insufficient, which leads to the abnormal use of electrical equipment in the car. If there is electricity, it won't turn on, which may be caused by the damage of the vehicle-mounted navigation line. With the extension of service time, many lines will show signs of aging. The failure rate of automobile central control panel is high, and touch screen failure is one of the phenomena. The touch screen of the central control panel in the car is out of order, probably because many trivial files occupy the system memory and crash after using the screen for a long time. You need to prepare a paper clip or toothpick, and then directly poke the RST hole of the central control panel to restore the central control panel to its initial state.
However, if the touch screen of the central control panel of the automobile still fails after the initial state is restored, it may be because there is something wrong with the contacts of the screen and it needs to be replaced directly. After all, there are many complicated circuits integrated in it. If the installation is unprofessional or wrong, it is likely to lead to a series of faults on the central control screen, and even burn out the interior parts of the car, which will have certain security risks. Needless to say, no matter any vehicle vibrates, there are high acceleration and large amplitude and low acceleration and small amplitude according to the user's situation; Because the vehicle is used outdoors, it is inevitable that the sunlight will be deflected or even direct.
Usually, the on-board computer obtains power directly from the on-board battery. Due to the different use conditions of various batteries and the instantaneous impact of ignition and flameout, the power supply requirements for supporting equipment are very high. Otherwise, it is easy to damage the equipment; Most areas are located in subtropical and temperate regions, with vast territory and extreme vehicle temperature environment, which may be between -30 and 70 degrees Celsius, which is a test for vehicle-mounted equipment; Special vehicles, especially police and medical vehicles, cannot use only one kind of electrical equipment. Unqualified electromagnetic radiation will bring serious interference to other equipment, such as digital broadcasting stations and medical high-precision physical mark monitoring. With the function keys, it can bring great convenience in the unstable automobile environment and improve the use efficiency.
