ColorQuest XT Touch Screen has lost sensitivity Follow
FAQ: “…The CQXT Touch Screen is working but, bout 80 percent of the time, your first press will work.”
Over time, there can be a buildup of skin oils from pressing and this can de-sensitive the CQXT touch screen.
Dampen a Kim Wipe with isopropyl alcohol or similar lens cleaner and gently wipe the screen. Repeat this several times until all skin oils are removed from the screen.
Re-calibrate the touch screen using this procedure - https://support.hunterlab.com/hc/en-us/articles/206620506-How-to-calibrate-the-Touch-Screen-on-a-ColorQuest-XT
If you run this touchscreen calibration procedure and the screen still does not have good sensitivity, the Touchscreen Overlay (HL Part # D02-1014-800) may need to be replaced. This is a film that covers the LCD screen and is connected to the processor board via a ribbon cable.
With care, it is possible for you to replace this part onsite. Or, contact HunterLab Service for screen replacement options.
