Confirm all USB cables are connected
With the majority of touchscreens, they will be connected to the media player via a USB cable. Confirm that this USB cable is not disconnected in any way shape or form. If it is indeed connected, try removing it from the USB port that it is currently plugged into, plug it into a different port, and then reboot the media player. If this does not correct the issue, proceed to the next step.
Contact hardware vendor
If your Touchscreen monitor was purchased from Rise Vision or Rise Display, reach out to firstname.lastname@example.org with a brief description of the issue, the name, and if possible the Display ID of the Display used as a touchscreen, and the troubleshooting actions taken so far.
If you did NOT purchase your touchscreen from Rise Vision, please contact the manufacturer or reseller who you purchased the touchscreen from for the appropriate next steps to take.
