3.4  Touch Screen Care and Clean 

Only use soft non-abrasive lint free wipes with Isopropyl 99% to clean dirt or stains 

found on the touch panel. Always dampen the wipes and then clean the touch panel. 

Chemical liquids with strong acidic base will damage the touch screen and void the 

warranty. 

 

3.5 Troubleshooting 

If you experience operational difficulties with the touch screen system either during or 

after installation, the following sections will help you to determine the source of 

problems. 

 

The first step in troubleshooting is to determine whether the problem is related to the 

display, software, or hardware. And please pay attention to special notes as follows.   

  Do not confuse display problems with touch screen problems, as the two 

issues are unrelated. 

 

Software problems are determined by a basic hardware functionality test. If the 

hardware transmits touch coordinates correctly, then the problem is probably 

with the driver or application software. 

  Hardware problems may be caused by the touch screen, controller, cabling, 

power supply, or the integration of the touch screen components in the display. 

 

3.5.1 Display 

Problems 

If the display has some problems (such as no video, no horizontal or vertical 

synchronization, raster non-linearity, etc.), remember that the video function of the 

display and the touch screen installed on the display are separated systems. 

Therefore, problems with the display should be treated as display problems, not 

touch screen problems. Diagnostic procedures and any possible corrections for 

display problems should be performed. 

 

3.5.2 Video 

Alignment 

Problems 

If the touch screen is responding and the data is linear, but it does not respond at the 

appropriate zone, try to align the video. Use 

Touchkit 

program. 

 

3.5.3 Software 

Troubleshooting 

Before beginning software troubleshooting, verify that the touch screen hardware is 

working normal for serial controllers by running the touchscreen program. If the
