Common problems of touch all in one machines
Common problems and solutions of touch all-in-one machines
Touch all-in-one machines are one of the indispensable products in today's commercial display human-computer interaction equipment. Usually, there are capacitive touch all-in-one machines and infrared touch all-in-one machines on the market, but there is not much difference except for some specific functions. For example, the display screen and touch screen of the infrared touch all-in-one machine are not two-in-one, so when the touch of the touch all-in-one machine is broken, can it be repaired? First, we have to analyze the fault of the touch all-in-one machine to determine whether it can be repaired:
First: The response time after touch is too long
This may be that there are moving water droplets or dust on the touch screen all-in-one machine. Just wipe it with a dry soft cloth, but it does not rule out that the host configuration may be too low, resulting in a long response time.
Second: Touch deviation
This may be that the debugging is not in place when installing the driver, and there is a vertical touch in the center of the bull's eye.
Third: Touch does not respond after use
This situation can only be judged step by step: first check whether the "display energy saving settings" are set to turn off the hard disk. The specific method is to right-click the mouse 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" to "Always On". Secondly, it may be that in some applications, due to poor grounding performance, the control box shell is covered with a large amount of static electricity, which affects the working electric field inside the control box and causes the touch to gradually fail. At this time, use a wire to ground the control box shell and restart it. In addition, since the surface of the smart touch all-in-one machine is covered with sound waves when it is working, if it is not wiped for a long time, excessive dust accumulation will block the reflection stripes of the wave, which will also cause the touch all-in-one machine to not work properly. For this, just use a clean business card or banknote to gently wipe off the dust on the surrounding reflection stripes through the gap between the front cover of the display and the smart touch all-in-one machine, and then restart the computer. For the touch all-in-one machine, you can open the front cover of the display, wipe off the dust on the surrounding reflection stripes with a clean towel, and then restart the computer. In addition, some touch-screen all-in-one control boxes use the method of taking power from the all-in-one power supply instead of the host. This only requires checking whether the 5V output of the all-in-one power supply is correct. Sometimes the instantaneous current is too large to burn the fuse, and the fuse needs to be replaced at this time.
Fourth: Partial no response during use
This may be that the reflective stripes of the touch query all-in-one machine are partially covered, and can be wiped clean with a dry soft cloth. It is also possible that the reflective stripes are partially scraped off by a hard object, but in this case the touch query all-in-one machine cannot be repaired and can only be returned to the touch all-in-one machine manufacturer for the manufacturer to handle it.
The above types of situations are the common faults and solutions of the touch query all-in-one machine. If it can't be solved, the touch all-in-one machine can only be returned to the manufacturer for repair. After the manufacturer verifies that if the touch frame of the touch all-in-one machine itself is not working and damaged, the merchant will have to handle it after sales. If we are not familiar with the touch all-in-one machine itself, then we do not recommend that users disassemble the machine privately and remove the touch frame for repair to prevent inconvenience to reasonable after-sales service in the future.
