LCD is either on but blank, or glitchy beyond usable?

Sometimes, my Keurig’s screen will turn on but be completely blank, or the graphics of the cup sizes and the “strong” toggle will be in the wrong spots of the screen, or it’ll be an incomprehensible mess. It makes coffee just fine. The display is the only thing wrong it seems. Should I just replace the LCD or both the LCD and the board, just to be safe?
