Nowadays, wall-mounted network advertising machines can be seen in shopping malls and office buildings. Its existence represents the progress of our technology, and it is also one of the most used advertising communication equipment. However, the wall-mounted network advertising machine occasionally fails during the use process, which will bring some trouble to the user. Now we will talk about the solutions to the three common faults of the wall-mounted network advertising machine. The introduction is as follows:
In daily applications, the flickering of the screen of the wall-mounted network advertising machine is a problem that users often encounter. In this regard, the user should first check the external factors such as magnetic field and power supply voltage around the device to exclude it. If it still cannot be used normally, it is necessary to conduct a comprehensive inspection of the graphics card driver of the display to eliminate the problem of program installation. After the above operation is invalid, the user can also try to increase the refresh rate to 75HZ to see if it is feasible. If the above operations cannot achieve satisfactory results, professional assistance is required, and the user needs to send the equipment to the repair station for inspection.
No response after the wall-mounted network advertising machine is plugged in is a problem that often occurs in practical applications. In this regard, the user can try to remove the advertising machine, open the back cover of the advertising machine, check whether the special power supply is powered on, and whether the existing material is falling off or loose. Specific method: check whether the indicator light is on, if it is normal, it means that the power supply is powered. If the power supply problem is ruled out, the user should check the power-on status of the decoding board, the advertising machine driver board, the high-voltage bar, the speaker, and the LCD screen in turn. Where there is no power, it means that there is a problem with the accessories of the advertising machine.
The screen goes black and displays "Signal out of sync range" or "OUT OF RANG": This phenomenon is a thorny problem that users often see in practical applications. Generally, the signal sent by the computer exceeds the display range of the monitor, and the monitor detects an abnormality. Caused by signal stop working. In this regard, the user can try to restart the display of the wall-mounted network advertising machine and reset the output frequency of the computer.
The introduction of common fault solutions of wall-mounted network advertising machine, I hope to help you, only if you understand the relevant knowledge, can you better solve the problem.
