Controller not turning off when powering down due to backfeeding of the screens power to the controller

In some rare occasions, sometimes the controller will not power fully off due to the screens independent power back feeding through the usb touch cable plugged into the back of the controller.
There are two solutions:

  1. unplug the touch usb cable
  2. purchase this add on that only allows the power to flow one way and enables you to shut down the controller and leave the touch cable plugged in:

*please note, this is a limitation of the raspberry pi computer we use inside the controller and not a software issue. There is nothing Onefinity can do to ‘fix’ the issue in software.
