Question about Texas Instruments TI-84 Plus Calculator
Batteries. Batteries. Batteries.
That is the description of what happens to TI Graphing Calculators when the battery power diminishes. The calculator will always reduce its display contrast in order to maximize time till expiration. There should have been prompts to warn you of its impending doom.
So, if it was very dim one day, and failed to display another day; then it most likely lost its battery power.
REPLACE THE BATTERIES.
By the way, your calculator has lost all of its memory when it completely diminishes. So, if you want to avoid losing all of your content then I would suggest your replace the batteries before battery expiration.
