My touch screen doesn't work properly

  • Is the system a touch screen thin client (ie HELIOS, ADITI)?
  • Is the touch screen in working condition, without worn spots, cracks, cuts, etc.?
  • Is the touch screen clean?
  • Are the proper touch screen drivers installed?
  • Does the system have a privacy filter or screen protector installed?
    If Yes, is the privacy filter in working condition, without cuts, worn spots, bubbles, etc.?
