Maybe the Kindle is frozen on that screen. The Kindle HDX User Guide suggests a hard reset by holding down the power button for 20 seconds before releasing it. That should shut the Kindle down. Be sure to not have the Kindle on a charger or hooked up to a USB cable during the hard reset. Next restart the Kindle. If that fails then charge the Kindle as you would normally do and when done detach the charger and USB cable and try another hard reset. If all fails go to www.amazon.com/kindlesupport.
