What should I do if the computer touch screen of the all-in-one computer does not respond? [All-in-one machine failure] All-in-one computer touch screen does not respond. Solutions to common faults of all-in-one touch screen
Common fault solutions for touch screen all-in-one machines
1. Inaccurate touch screen [Troubleshooting]
A five-wire resistive touch screen cannot perform the corresponding operation normally when touching the part of the display screen with a finger.
[Failure analysis and treatment]
This phenomenon may be a problem with the proofreading of the resistive screen.
The screen calibration program can be run under the following conditions: (Open the touch screen software calibration program on the desktop) 1) Complete the driver software installation for the first time.
2) After changing the resolution or display mode of the monitor each time.
3) After changing the displayed display area each time.
4) After adjusting the frequency of the controller each time.
5) Every time the cursor cannot correspond to the touch point.
After calibration, the calibrated data is stored in the register of the controller, so there is no need to calibrate the screen every time the system is started.
2. The touch screen does not respond [Troubleshooting]
A touch screen does not work, and there is no response when touching any part.
[Failure analysis and treatment]
First check whether the wiring interfaces are 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 the conflict. Then check whether there are cracks on the surface of the touch screen. If there are cracks, replace them in time.
If the above parts are normal, the touch screen can be checked by replacement method, first replace the control box, then replace the touch screen, and finally replace the host.
The following maintenance can be carried out:
1) Check whether the wires of the touch screen are connected. 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.
2) If the above conditions are not confirmed, please delete the touch screen driver and restart the computer to reinstall the driver.
3) If the touch screen has been used for a long 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.
3. The touch screen has a long response time [Troubleshooting]
A touch screen, after touching the monitor screen with a finger, it takes a long time to respond.
[Failure analysis and treatment]
This may be caused by a virus on the host or system chaos.
1) First check whether the host has a virus, if there is, kill the virus first.
2) There is a problem with the system, check whether it can be adjusted, if not, reload the system.
