Glo Kobo Glo Aura fractured Screen

My Kobo Glo, I think Aura first generation booted up with a fractured screen, , areas blank and one kind of striped and one with an old book cover on it. It's never been wet, or dropped..Is this something that flashing from a new image could cure. The way the screen is showing up in sections, I can't go in and do a new person startup. Am hoping there is a way to get a f sd card flash image (think that's what it's called) and start over.
Thanks:help:
