1. Fault analysis of TPC-60SN-E1: Touch unresponsive phenomenon: When touching the screen, the mouse arrow does not move or change position.
Reason: There are many reasons for this phenomenon, which will be explained one by one below: the dust or scale accumulated on the sound wave reflection stripes around the surface acoustic wave touch screen is very serious, causing the touch screen to not work; Touch screen malfunction; Touch screen control card malfunction; Touch screen signal line malfunction; The serial port of the computer host has malfunctioned; The operating system of the computer has malfunctioned;
2. Touch screen driver installation error.
Solution: Observe the touch screen signal indicator light. Under normal circumstances, the light flashes regularly, approximately once per second. When the screen is touched, the signal light remains on. After stopping the touch, the signal light resumes flashing. If the signal light is still on normally without touch, first check if the touch screen needs to be cleaned; Next, check whether the serial port number connected to the hardware matches the serial port number set by the software, and whether the serial port of the computer host is working properly. Run the COMDUMP command on the driver disk, which is a DOS command. When running, add a space and the serial port code 1 or 2 after COMDUMP, and touch the screen to see if there is data rolling out. If there is data rolling out, the hardware connection is normal. Please check if the software settings are correct and if there are any conflicts with other hardware devices. If there is no data rolling out, the hardware will malfunction, and the specific fault point is yet to be determined.
