Question about Texas Instruments TI-83 Plus Calculator
Could be the screen has been dimmed so much that you can't tell that it's coming on. Press on and then 2nd button and the up arrow key. You may need to keep pressing 2nd and up arrow key. This is how you darken the screen. You can also lighten the screen which may be the problem you have by pressing 2nd and then the down arrow key.
If this doesn't work, take out the internal battery that is located in a tiny door with a screw right above the 4 AAA batteries. Leave this out for about 8 hours and put it back in. Put in the AAA batteries and the calculator will be reset and may work.

Your tint could have been reset. Try pressing the 2nd button then the up arrow. Repeat these two button combinations the see if the tint darkens so you can see the cursor.
