1、通讯故障，下位机通讯程序没有设定对、触摸屏系统地址没有正确、通讯口烧毁、通讯线路短线或者没有接对，接触不良等都会造成通讯故障； 

2、触摸玻璃，这是和人手接触较多的地方，也是容易出问题的表面层，一般这类型的故障是由于使用人员操作使用不当粗鲁动作引起的，有些是运输等不小心造成，结果一般都是破碎，偶尔也可能发生里边电阻等器件断裂，这种故障只有换触摸玻璃，因为各种厂家生产时候规范标准不同，所以往往更换的时候存在内部配件匹配的过程，有完全可以匹配的配件，那么触摸屏维修是很简单的事情了，就是更换后校准后就可以正常使用了。 

3、显示的液晶没有显示或者显示不正常,这有同触摸玻璃类似的外力因素造成的损坏，但不太多，大多是液晶老化引起的，也是靠更换处理，同样存在不同厂家不同规格液晶不一样的问题，另外一种原因是液晶驱动损坏了造成的，这类问题就需要处理电路板了。

1, communication failure, the communication program of the lower machine is not set, the touch screen system address is not correct, the communication port is burned, the communication line is short or not connected, and the contact is poor will cause communication failure; 

2, touch the glass, which is in more contact with the human hand, is also prone to problems on the surface layer, generally this type of failure is caused by improper use of personnel operation and rude actions, some are caused by transportation and other careless, the result is generally broken, occasionally may also occur inside the resistance and other devices fracture, this failure only change the touch glass, Because the specifications and standards of various manufacturers are different, there is often a process of matching internal accessories when replacing, and there are fully matched accessories, so the touch screen maintenance is a very simple thing, that is, it can be used normally after replacement and calibration. 

3, the display of the liquid crystal is not displayed or the display is not normal, which has damage caused by external factors similar to the touch glass, but not too much, mostly caused by the aging of the liquid crystal, but also by replacement, there are also different manufacturers of different specifications of the liquid crystal is not the same problem, another reason is caused by the liquid crystal drive damage, such problems need to deal with the circuit board.
