No response after using for a while
[Fault phenomenon: A touch screen will not respond after a period of normal use after booting.
[Fault Analysis Processing: 1) Check if the hard disk is turned off in the "Display Energy Saving Settings" of the Windows 9x. The method is to right-click on the desktop, select the "Properties" command, then select the "Screen Saver" tab from the dialog box, click the "Settings" button, set the parameter to "Always open" except "Power Scheme" In addition, the rest are “never”.
2) In some applications, due to poor grounding performance, the control box housing is covered with a large amount of static electricity, which affects the working electric field inside the control box, resulting in the gradual failure of the touch. At this point, use a wire to ground the control box housing and restart it.
3) Since the surface of the touch screen is covered with sound waves when the surface acoustic wave touch screen is working, if the touch screen is not rubbed for a long time, the dust accumulates too much, blocking the reflection stripe of the wave, and the touch screen cannot work normally. For touch displays, use a clean business card or banknote to gently wipe off the dust from the surrounding reflective strips through the gap between the front cover and the touch screen, and then restart the computer. For the touch-sensitive unit, open the front cover of the monitor, wipe the dust off the reflective strips with a clean towel, and then restart the computer.
4) Many touch-one machine touch screen control boxes adopt the method of taking power from the integrated machine power instead of taking power from the host. Therefore, it is also necessary to check whether the 5V output of the all-in-one power supply is correct, and sometimes the instantaneous current is too large, causing the fuse to be burned. The fuse needs to be replaced.
