IPF605 no text on screen after firmware update

[slowsl]

Long story short, I upgraded our IPF605 firmware with the update tool from canon. Everything seemed fine that day.  The printer was shut down that night.  When I turned it back on a few days later, the screen backlight comes on but there is no text showing.  All functions work, however I can't do much without being able to see the screen.  Any ideas?
