In the era of information technology, vertical touch advertising machines, as a product of the new era, have gradually entered our lives. However, many people do not understand the vertical touch advertising machine, and the incorrect use will cause problems with the machine. Today, let's take a look at the problems and solutions of the daily use of vertical touch advertising machines!
1. When the vertical touch advertising machine is switched on and off, there are interference patterns on the screen.
Generally speaking, this phenomenon is caused by the signal interference of the display card, which is a normal phenomenon, and the user can solve it by adjusting the phase automatically or manually.
2. A thumb-sized black spot appears on the display screen
The engineer of Beijing Yueshi vertical touch advertising machine manufacturer pointed out that this phenomenon is mostly due to the extrusion of external force. Under the pressure of external force, the polarizer in the liquid crystal panel will be deformed. This polarizer is like aluminum foil. It will not bounce up by itself after being pressed into the recess. This causes the difference in the reflection of the liquid crystal panel, and there will be a dark part. This Some parts are easy to find under the white screen, and the general size is more than ten square millimeters, which is the size of your thumb. Although this phenomenon will not affect the service life of the LCD screen, it will still affect the overall appearance, so users should pay more attention and do not press the LCD screen with their fingers.
3. No response after plugging in the power
This is the most common problem in practical applications. For this problem, the user can try to open the back cover of the Baoqianli vertical touch advertising machine to check whether the special power supply is powered on, and whether the existing material is falling off or loose. Specific method: Use a multimeter to measure whether the indicator light is on, if it is normal, it means that the power supply is powered. The power supply problem is ruled out, and the user should check the power-on status of the decoder board, the vertical touch 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 vertical touch advertising machine.
4. There is no display on the screen, and the indicator light on the front panel flashes
After this problem occurs, the user should check whether the signal line between the monitor and the computer is firmly connected, and check whether the connector of the signal line has broken pins, bent or other damage.
Be sure to pay attention to the temperature and humidity of the area where the vertical touch advertising machine is located. Unsuitable temperature and humidity will also cause certain damage to the machine!
