1. The response time of the touch screen is very long, which may be caused by a virus in the host or a chaos in the system;
Solution:
1. Check if the host is poisoned first, if it is, check and kill the virus first;
2. If there is a problem with the system, it should be checked whether it can be adjusted, if it can be adjusted, if not, the system should be reloaded directly;
2. No response to touch
First of all, we need to check whether the interface of each wiring is loose, and then check whether the serial port and interrupt signal conflict. If there is conflict, we should adjust the resources to avoid conflicts, and then check whether there are cracks on the surface of the touch screen. If there are cracks, they should be replaced in time. If these parts are normal, you can use the replacement method to check the touch screen. We first replace the control box before replacing the touch screen and the host, etc.;
Maintenance method:
1. Check whether the connection of the touch screen is true or not, among them, whether there is a connection to the keyboard port of the host is connected, so check the connection first;
2. If it is confirmed that it is not the above situation, you can delete the touch screen driver and restart the computer to install the driver;
3. If the touch screen has been used for a relatively long time, for example, after several years of use, and some areas of the touch screen are found to be unwieldy and cannot be touched, it may be that the touch screen is broken. The solution is to replace the touch screen;
3. Part of the touch screen does not respond
This could be that part of the touch screen is damaged by a hard object. Generally, there is no way to repair it. The only solution is to replace the touch screen;
4. There is no response when the touch screen is started for the first time after installing the driver
We must first determine whether the cable connection of the touch screen is correct. If it is not correct, it should be turned off, and then connect all the lines correctly, and then check whether there is a device conflict with the serial port resource in the host, check each hardware device and adjust it ;
Five, the touch screen can work normally but cannot operate it
It may be that before the host starts to load the touch screen driver, the touch screen control card receives the Cao group signal, only need to cut off the power, and then restart the computer;
