Digital Display Lit But Lettering Is Not Visible.

Over last 2 weeks my Calisto P540M digital display information began to "fade" and is now completely invisible. I tried shutting down and cutting power to the PC at night a few times. The next morning the letttering would be visible but would begin to fade throughout the day. Powering up today... the display still has the back light but the lettering is not visible. Any suggestions?
