With your Lippert Ground Control 3.0 Electric 5th Wheel RV Leveling System- 6-Point Set # LC675817 or 4-Point Set # LC358590, if the control panel is reading blank, we have found that a lot of times that simply unplugging the panel and then plugging it back in will reset the unit and the screen will come back.
