Learn how to resolve some commonly reported Elo Touchscreen issues in the following article, including the screen being black and not responding properly to touch.
Kiosk Screen is Black
If the touchscreen is completely black, it's possible that the screen and/or kiosk may be powered off. Be sure both the screen and the CPU are powered on by completing the following steps:
1. Power on Kiosk
Be sure the kiosk is powered on by checking for the blue light on the side. If the kiosk is not receiving power, turn on the kiosk and check to see if the screen powers on normally.
2. Power on Touchscreen
If the kiosk is already powered on, open the kiosk and press the Touchscreen Power button. Check that the kiosk computer is powered on.
3. VGA Cable to CPU
Be sure that all connections running from the back of the touchscreen to the kiosk computer are fully seated. Make sure the VGA cable screws are tight and secure.
4. ELO Power Supply
Verify that the power supply is plugged in by checking for the green light illuminated on the ELO power brick.
If the touchscreen does not power back on after you have confirmed that all connections are secure, restart the kiosk and try again.
If the touchscreen still remains black, it is possible that the backlight inside the monitor is burnt out. Try shining a flashlight onto the screen. If an image becomes visible, contact 365 Support at (888) 365-6282 for further assistance.
Touchscreen does not Respond to Touch
An dirty or smudged touchscreen can affect the way the monitor registers touch. In addition, dirt buildup along the inside edge of the kiosk chassis or over-tightened screws can cause "deadspots" on the screen. Learn more about the maintenance of the ELO Touchscreen in our guide Cleaning Instructions for Multiple Devices.
If after cleaning the touchscreen, it is still not responding to touch, the screen may need to be recalibrated and/or the software reinstalled. Contact 365 Support at (888) 365-6282 while on site for assistance with recalibrating the touchscreen.
