Fault 1: No response on touch screen

Phenomenon: Sometimes the smooth touch screen refuses to work since it has no any response when you touch any part of it.

Analysis & solution: First of all, you should check the wiring interface to see whether it is loose, and then check the serial port and the interrupt number to see whether there is a conflict.  In order to avoid conflict, you should adjust the resources properly. In addition, you should check the touch screen surface to see whether it has cracks. If you find any cracks, you should replace it. Of course, you should always keep the touch screen clean and use a soft cloth to clean it frequently to avoid dusts on the surface. Under normal circumstances, the indicator light on the control box is green and blinks if it works properly. If the above problems are all normal after checking, you may replace the touch screen or control box or the host to confirm the faults. Using the replacement method can find the fault of touch screen and solve it finally.

Fault 2: Too long response time on touch screen

Phenomenon: When you use finger to touch the monitor screen, it takes a long time to response.

Analysis & solution: If the touch screen response time is too long, the possible reasons may be that there are some small water droplets on the screen or the host grade is too low. If there are water droplets on screen, you may use a dry soft cloth to wipe it to make it clean. If the host grade is too low, the best way is that you replace a new one.

Fault 3: No response for touch screen local

Phenomenon: When you use your finger to touch the smooth monitor screen, the screen local has no response.

Analysis & solution: The reason may be that the touch screen reflection stripes are partially covered. At this time, you may clean it gently using a dry soft cloth. If the touch screen reflection stripes are scratched seriously, you have to change a new one since it cannot be repaired.
