Pressing 2nd then the up or down arrows is how you change the contrast on the TI-83. All you need to do is press the 2nd key then hold the down arrow to get your screen back. The countdown that you saw was just the value the calculator assigns to the contrast. It goes from 0-10.

Hope that helps!

TI-83 Plus completely blank and won't turn on. All batteries are fine.


TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

On TI-83 How do you change the batteries?


Try pressing the 2nd key and then holding down the up arrow key first.  This changes the contrast on the screen- makes it darker.  Pressing the 2nd key and then holding down the down arrow key will make the screen lighter
