First, check whether the wiring interface is loose, and then check whether there is a conflict between the serial port and the interrupt number, if there is a conflict, the resources should be adjusted to avoid the conflict. Then check whether there are cracks on the surface of the touch screen, and replace them in time if there are cracks. It is also necessary to check the surface of the touchscreen for dirt and dirt, and if so, use a soft cloth**. Observe and check whether the indicator light on the control box is working properly, and when it is normal, the indicator light is green and flashing. If the above parts are normal, you can use the replacement method to check the touch screen, replace the control box first, then replace the touch screen, and then replace the main unit.
If it is a resistive touch screen, it can be overhauled as follows:
1) Check whether the connection of the Weilun Tong touch screen is right, and whether one of the cables connected to the keyboard port of the host (take the working voltage of 5 volts touch screen from the keyboard port) is connected, please check the connection.
2) Observe the light of the touch screen control box, if it is not lit or the red light is on, it means that the control box is broken, please replace it.
3) If it is confirmed that it is not the above situation, please delete the touch screen driver and restart the computer to reinstall the driver, or replace the driver with a later version.
4) Check whether there is a conflict between the device and the serial port resource in the host, check the hardware device and adjust it. For example, if the default IRQ of some NICs is 3 and conflicts with the IRQ of COM2, you should change the IRQ of the NIC to an idle and unused IRQ. It may be that the computer motherboard and the touch screen control box are not compatible, please replace the main unit or motherboard.
5) If the touch screen is used for a long time (3-4 years) and you find that there are some areas of the touch screen that cannot be touched, it may be that the touch screen is broken, please replace the touch screen.
