Touch Screen

After running a Penmount touch screen calibration test, it restarts

Models affected: TL7200, TL7400, TL7600, TL8400

The touch screen is either damaged, or the internal hardware is likely defective.

To run an initial check to your integrated touch thin client of whether the repair may be an in-warranty or out-of-warranty repair, check for cuts, faded areas or cracks across the screen, or damage to the system's plastic housing.  Any physical damage voids the system warranty.

What products can I use to clean my touch screen?
  • Turn the device OFF prior to cleaning.
  • Use any standard glass cleaner to clean the touchscreen - AVOID PRODUCTS CONTAINING AMMONIA.
  • DO NOT spray glass cleaner directly on the LCD - it could leak inside a non-sealed unit and cause damage.
  • Spray glass cleaner on a cloth / towel and then clean the touchscreen. A clean microfiber cloth can also be used.

I can only calibrate the touch screen to 4-point accuracy (Penmount)


Models affected: TL7200, TL7400, TL7600, TL8400

Increase the number of points to calibrate the touch screen using the Advanced properties of the touch screen software.

What can I use to operate the touch screen?

Use a Thinlabs-approved stylus or your finger on a touch screen.
DO NOT USE PENS, PENCILS or OTHER SHARP OBJECTS -
that will damage the touch screen and void the system warranty.

Systems with resistive touch screens (TL7400, TL8400 models) require use of a resistive touch stylus.

Systems with IR touch screens (TL2420, TLI8400, TL8600 models) require an IR touch stylus.

Systems with pCAP touch screens (TL2440, TL2640, TL8610, TL8620 models) do not require a stylus.

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.?
