Due to the continuous improvement of science and technology, there are many resistance touch screens around us, which brings great convenience to our life and work. Before using the resistance touch screen, you should carefully read its operation manual to know the specific operation method to avoid problems. Sometimes, we have problems with the resistive touch screen. What should we do? Today, I’d like to learn about the maintenance methods of resistance touch screen with you. They are as follows:

1) Check whether the connection of the contact screen is correct, and whether one of the wires connecting to the keyboard port of the host (take 5 V contact screen operating voltage from the keyboard port) is connected. Please check the connection.

2) Investigate the condition of the touch screen control box lamp. If it is not on or the red light is on, it indicates that the control box is broken, please replace it.

3) If you are sure that this is not the case, please remove the touch screen driver and restart the computer, re install the driver, or replace the driver with a newer version.

4) Check whether there are devices in the host computer that conflict with serial port resources to check and adjust each hardware device. For example, the default IRQ of some network card devices is 3, which is in conflict with the IRQ of com2. At this time, the IRQ of the network card should be replaced with the IRQ which is not used in leisure. It may be that the computer motherboard and the touch screen control box are not compatible. Please replace the host or the host board.

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