2. Touch the screen of the all-in-one machine to display the black dot of the thumb.

This appearance is mostly formed by external kneading. Under the pressure of external force, the polarizer in the liquid crystal panel will deform. Polarized mirror image aluminum foil will not pop up after being pressed. This makes the LCD panel different when reflecting light, which will appear dim. Some of them are easy to find under the white screen. Usually the size is more than ten square millimeters, but the thumb is too small. Although this appearance will not affect the service life of the LCD, users should pay more attention not to press the LCD with their fingers.

3. There is no sound when touching the all-in-one machine.

After asking this question, the user can first open the back cover of the advertising machine, use a multimeter to check whether the function of the drive board is powered on, and then check whether the connection of the horn cable is normal. If there is a loud horn noise, it indicates that the driving board of the touch all-in-one machine has been damaged and should be replaced immediately.

There is no response after the touch all-in-one machine is plugged into the power supply, which is often a problem in practice. In this regard, the user can try to remove the all-in-one machine, open the back cover of the all-in-one machine, check whether the special power supply is powered on, and whether the existing materials fall or become loose. Specific measures: whether the indicator light is on when 10000 doses are used; If normal, the power supply is powered on. To clear the power problem, the user should check the power on status of the decoder board, touch all-in-one machine drive board, high-voltage line, speaker and LCD in turn.

5. Touch the screen of the all-in-one machine to show a shiny appearance.

In normal use, touching the screen flash of all-in-one machine is a problem often encountered by users. In this regard, the user should first check the external factors such as magnetic field and power supply voltage around the equipment. If it still cannot be used, it is necessary to comprehensively check the graphics card driver of the visualization tool to clear the doubts of the program device. After the above operations are invalid, the user can also test the progressive refresh rate of 75Hz to see if it is feasible. If the above operations cannot meet the requirements, the help of professionals is required, and the user needs to send the equipment to the maintenance station for inspection.

6. The screen is black and displays "signal exceeds synchronization scale" or "out of range"

This appearance is often seen by users in practical use, usually because the signal published by the computer exceeds the display proportion of the visualization tool, and the visualization tool stops working when it detects an abnormal signal. In this regard, the user can test, restart the visualizer and reset the output frequency of the computer.

Audio HD appears. With the development of Digital HD, LCD mosaic TV wall towards digital HD will be a main direction. Third, large screen LCD splicing screen intelligent LCD splicing TV wall. The embedded system is becoming more and more powerful. In the future, more intelligent designs will be integrated to make the system operation more convenient and fast. System debugging is certainly the first priority of intelligence. The LCD splicing TV wall is composed of a plurality of LCD splicing pieces.

7. The touch screen of the all-in-one machine does not appear, and the indicator light on the front panel is on.

After this problem occurs, the user should check whether the connection between the visualizer and the computer signal line is firm, and check whether the socket of the signal line is damaged due to broken pin and kink.
