HSI Not displaying (2013 Prius)

Hey everyone! My aunt is having an issue with her car, and i thought maybe y'all could help.

The issue derives from the Hybrid System Indicator display. The display turns on, and will display the "maintenance required" message, but when clicking the DISP button, it will only cycle between that, settings, and a completely blank screen (aside from the clock and the trip indicator) When pressing the TRIP button, only the miles driven for the trip, the odometer, and the miles to empty will display. I tried clearing the maintenance data, but that didn't do anything, and now pressing DISP only cycles through the settings page and a blank screen. The car still goes into ready mode just as quickly as it should, and still drives like normal.

Any ideas?
