Question about Texas Instruments TI-83 Plus Calculator
You may need to adjust your contrast. After turning the calculator on, press the 2nd button and then hold down the down arrow. This will lighten the screen if the contrast is the problem.
If this doesn't work, you might try resetting your calculator. Take out the backup battery that is located behind a little door with a screw right above the 4 AAA batteries. Leave all batteries out for about 8 hours and then reassemble. Hopefully when you turn it on, this will work. Good luck
