How to deal with the failure of floor standing advertising machines in daily use?
LCD advertising machines, with their powerful functions, colorful display methods, and high cost-effectiveness, are an important channel for commercial advertising and information dissemination in today's era. They can be seen in many public places, wall-mounted, floor-standing, of various sizes and styles. Advertising machines are electronic devices. During use, especially after a long time, some large and small failures are inevitable. Many users do not know how to deal with problems due to their lack of technical knowledge of advertising machines. Below, Beloong Advertising Machine Manufacturer will introduce some common failures of floor-standing advertising machines and how to deal with them correctly.
Common failures of floor-standing advertising machines are as follows:
(1) The screen of the floor-standing advertising machine flickers during playback. First, we need to check whether there is any magnetic field interference signal around the advertising machine, or low voltage and insufficient power supply, which causes the device to fail to operate normally. If these two possibilities are excluded and it still doesn't work, it may be a problem with the device display graphics card driver, which needs to be fully checked or refreshed. If none of the above three methods work, you need to contact after-sales or professional technicians for inspection or repair.
(2) If the advertising machine cannot be started, check whether it is plugged into the power supply. If it still cannot be started after being connected to the power supply, check the internal power supply, open the back cover of the advertising machine, and check whether the power cord and other wires are loose and whether they are powered on. You can use a multimeter to check. If the indicator light of the multimeter is on, it means that there is power, indicating that there is no problem with the power supply. At this time, you should check whether the driver of the advertising machine is in normal condition.
(3) The screen of the advertising machine does not display anything, but the indicator light is on. At this time, it may be that the signal is interrupted. We need to check the signal connection between the display and the computer, and whether the signal cable socket is broken, bent, or damaged. If it is broken, just replace it.
(4) When the screen of the advertising machine is black and displays "The signal exceeds the synchronization range", it is possible that the signal sent by the computer exceeds the range of the monitor, resulting in a black screen. We can restart the computer and monitor and reset the refresh rate.
(5) There are spots on the screen. This is mostly caused by the screen being squeezed by external force, causing the polarizer in the screen panel to deform. After being squeezed by the outside, it will not return to its original state, so the panel will reflect unevenly and appear black. In order to make the LCD screen display normally, do not press the screen hard.
The above are several common problems and solutions introduced by Beloong. I hope it will be helpful to you.
