Summary
If there is a Touch Screen calibration issue during or after installation,
take the following actions in the order listed:
1. Perform the 2 ‐ Point Calibration .
2. If the calibration is unsuccessful after two attempts, then run the
Cursor Stabilization procedure.
3. Perform 25 ‐ Point Linearization (Windows).
4. Perform Restore Defaults .
5. If you are still unable to calibrate then change the touch screen
glass. (First, check the cable connections on the Touch Screen glass.)
6. The final step is to replace the Main controller Board. If this corrects
the problem, then the old glass is probably OK to reuse.
If there are problems in detecting the Touch Controller then:
1. Check that all harnesses on the Touch Sensor and Main controller
Board are firmly seated. Check that the Touch Sensor’s flex cable is
not cut or damaged.
2. Uninstall the Touch Driver; reinstall.
3. Replace the Main controller Board.
4. Check that the touch screen is not cracked or damaged.
5. Check to see if the Capacitive Screen or Bracket is touching the
LCD Panel or the LCD Bracket. (There must be no direct contact.)
6. Check for excessive dirt or debris against the gaskets, especially
along the bottom edge of the screen.
7. Replace the Touch Screen.
