Problem phenomenon: A contact screen has no response after normal use for a period of time after being turned on.
Problem profiling and processing
1. Check to see if the hard drive is turned off in the "Display Energy Saving Settings" of Wlndows9x. To do this, right-click on the desktop, select the "Properties" command, then select the "Screen Saver" tab from the dialog box, click the "Settings" button, and set the parameters to "Never" except for "Power Plan" which is "Always on".
2. In some applications, because of the poor grounding performance, the shell of the control box will be covered with a lot of static electricity, which will affect the operating electric field inside the control box, resulting in the gradual failure of the contact. At this moment, use a wire to ground the shell of the control box and restart it.
3. Because the appearance of the sound wave contact screen is covered with sound waves on the surface of the contact screen, if the contact screen is not wiped for a long time, it will lead to excessive dust accumulation, blocking the reflection fringes of the wave, which will cause the contact screen to not work normally. When it comes to touching the monitor, you can use a clean hand thorn or banknote to quietly wipe off the dust from the reflective stripes around the monitor through the gap between the front cover of the monitor and the contact screen, and then restart the computer. For contact all-in-one, open the front cover of the monitor, wipe the dust off the surrounding reflective streaks with a clean towel, and then restart the computer.
4. Many contact all-in-one contact screen control box adopts the way of taking power from the all-in-one power supply instead of taking power from the host, so you should also check whether the 5V output of the all-in-one power supply is correct, sometimes the instantaneous current is too large, resulting in the fuse being burned, and the fuse needs to be replaced at this moment.
