We have the EXACT same problem! Would love to hear a solution to this. It will eventually work again but we have no idea what brings it back to life. I've tried the reset button, unplugging and replugging numerous times and still get the KM and 579 showing up and then no power.

Solution:
press and HOLD the button that says display above it and Reset below it untill you see the normal start up Screen and yoru good to go!
