Have more questions? Submit a request
If the kiosk is only responsive in certain areas, or not responsive, check to ensure touchscreen is free from dust and debris, check cables for proper connectivity, and wipe and re-enroll the Chromebox if needed.


Please Note: These steps are for diagnosing issues on the Wondersign Catalog Kiosk App running on a 42" or larger Touchscreen.


Getting Started

Ensure Touchscreen is Free from Dust and Debris

1. The touchscreen may become unresponsive as dust & debris collect on the screen. Use a microfiber cloth (recommended) or a gentle application of canned air to clean the face of the screen.


2. The touchscreen uses a series of infrared sensors that run along the inside edge of the touchscreen. Ensure the edges (as indicated below) are also free from dust & debris.


Some touchscreen models also utilize an optical sensor on the inside corner of the touchscreen (see below). Please ensure the lens is also free of dust and debris.

If the touchscreen is still unresponsive, refer to the other troubleshooting steps in this article.


Check Cables for Proper Connectivity

1. Access the Chromebox that is connected to the ELO touchscreen, which is typically located in the kiosk stand.


2. Ensure the following cables are secured in the back of the Chromebox:


1. Power 2. Ethernet (if using WiFi, no cable will be attached)

3. USB (or)

3b. USB-C



3. Remove the cable cover located on the back right side of the monitor to access the touchscreen’s connector panel. Once removed, ensure the USB or USB-C cable from the Chromebox connects to the "Touch USB" port in the back of the touchscreen. Follow the same process for the HDMI cable running from the Chromebox to the touchscreen.


The ports used in the back of the touchscreen are indicated below.


Please Note: The HDMI & Touch USB ports connect to the Chromebox. The AC Power In connects to an electrical outlet.



4. Return to the touchscreen to ensure the kiosk is functioning properly. If not, continue to the next troubleshooting process below.
