If the USB cable is also good, see if there is a problem with the USB interface of the host. At this time We can plug in the USB cable of the mouse or keyboard and have a try. If there is a problem with the USB interface or the USB data cable, just replace it; then check whether each 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, adjust the resources to avoid Conflict; then check whether the wires of the touch screen are connected correctly. One of the wires connected to the keyboard port of the host (take the 5V touch screen working voltage from the keyboard port) is connected. Please check the connection. If it is a detachable structure, please re-check that the components are well connected and the connecting wire is not damaged.

2. Check hardware

Enter the device manager of the LCD touch screen panel pc to see if you can find the touch screen hardware (you can plug and unplug the cable to observe whether there is a device in the device manager), and then check whether there are cracks on the surface of the touch screen.

4. Troubleshooting software

If the above method does not work, you must consider that the touch software is running too much at the moment, which causes the touch screen all-in-one computer to have insufficient memory, and there is no response. Then the short-term solution is to boot and restart, but if you want to solve it in the long-term, you need to increase the memory bar.

Besides for the touch screen driver, the compatibility of your software may also cause this problem. You need to feedback this question to your engineer team or you ask the original factory for help.

5. Broken screen

If the touch screen has been used for a long period of time (3-4 years) and it is found that some areas of the touch screen cannot be touched, it may be that the touch screen is broken. Please replace the touch screen.
