Common failures of landing advertising machines are as follows:
(1) The screen of the display screen of the landing advertising machine flashes during the playing process.
First, we need to check whether there are any magnetic interference signals around the display screen of the advertising machine, or whether the equipment cannot operate normally due to low voltage and insufficient power supply.
If it is still not possible to rule out the two possibilities of the display screen of the advertising machine, it may be a problem with the driver of the display card of the equipment, which needs to be inspected comprehensively, or the hertz can be refreshed.
If the above three methods fail, you need to contact after-sales or professional technicians for inspection or maintenance.
(2) The display screen of the advertising machine can't start when it is turned on. Check whether the advertising machine is plugged in. If it is connected to the power supply or can't start, check the internal power supply, open the back cover of the display screen of the advertising machine, and see if the power cord and other wires are loose and powered on.
You can use a multimeter to detect whether it is powered on. If the indicator light of the multimeter is on, it indicates that there is electricity, indicating that the power supply is no problem.
At this time, you should check whether the driver of the display screen of the advertising machine is in normal condition.
(3) There is no display on the display screen of the advertising machine, but the indicator light is on. At this time, the signal may be interrupted.
We need to check the signal connection between the display screen and the computer, and check whether the socket of the signal line is broken or bent. If it is broken, just replace it.
(4) When the all-in-one advertising machine displays a black screen and displays "The signal is out of synchronization range, it may be that the signal sent by the computer is out of the range of the display, resulting in the black screen of the display. We can restart the computer and monitor and reset the refresh frequency.
(5) Flower screen and spots appear on the display screen of the advertising machine.
This situation is mostly caused by the screen being squeezed by external force, which leads to the deformation of the polarizer in the screen panel.
After being squeezed by the outside, it will not recover itself, which leads to uneven reflection of the panel and black.
In order to make the LCD screen of the advertising machine display normally, do not press the screen hard.
