Chapter 4 Troubleshooting
Before you start troubleshooting, check the following.
x Make sure your computer and monitor are working normally.
x Check that the touchscreen connectors are all inserted correctly.
To uch location and cursor position are reversed.
x Calibration is not run during the processes of driver installation.
Please run the function of Calibration.
Cursor constantly stays in a fixed position on the screen edges
or corners.
x During touchscreen installation, the display front bezel on that
position presses active area of touchscreen. Please stick sponges on
the inner four sides of the front bezel in order to prop the frame up.
x If sponges are already stuck, try to add one more layer, but the gap
between the touchscreen and the front bezel may be too big to
influence the appearance.
x If the cursor fixed position is on one of the four corners, try to loose
screws of the display on four corners.
Cursor shakes at a certain fixed position.
x Power supply or other high frequency device influences the display
or the touchscreen controller. First, make sure to keep the
ATouch User Guide

touchscreen’s tail away from display’s inverter and insulate against
the display device; Second, make sure that the touchscreen controller
is insulated, and keep it away from the display’s inverter.
Cursor shakes before the touchscreen controller is installed in
display.
x Maybe the touch sensor’s tail contacts the display’s inverter. Check if
the tail’s position is changeable. If it is hard to change tail’s position,
then stick thick insulating tape around the tail or stick a copper slice
with insulation on one side and electric conduction on the other side
to insulate the tail from the inverter.
To uch position is not accurate.
x Use the Calibration function of the ATouch Control Center program
to re-align.
x If the touch position is not accurate after the calibration, please check
whether the touchscreen driver you use is the newest version.
