With the TI-83's brighten control key functions, you can darken and lighten the pixels on the screen. The entire procedure can take less than a minute and only requires pressing two keypad keys. However, before you brighten the screen, check the batteries first. Low batteries will make it difficult to get the brightness you need to work with the TI-83 comfortably.
If the brightness and darkness controls don't change the level of brightness, try changing the TI-83 batteries. Remove the battery cover on the back and replace all four batteries with brand new ones. Don't try to replace just one or use batteries that you don't know the condition of. If that doesn't work, replace the backup battery that is within the main battery compartment. If you continue to have a problem, your TI-83 calculator may need professional repair.
Press the "On" key (row 10, column 1 on the TI-83 keypad) to turn your calculator on.
Press and release the "2nd" key(row 2, column 1, often a yellow-orange color) and then press and release the "down arrow" key (row 3, between the fourth and fifth column, with a white arrow pointing down) to lighten the screen. Observe the number in the upper right hand corner of the screen decreases by one for each press of the "down arrow" key. Press the "down arrow" key again to lighten the screen to the next brightness level.
Press and release the "2nd" key(row 2, column 1, often a yellow-orange color) and then press and release the "up arrow" key (between the second and third rows, between the fourth and fifth columns, with a white arrow pointing up) to darken the screen. Observe the number in the upper right hand corner of the screen increases in value by one. Press the "up arrow" key again to darken the screen to the next brightness level.
Press the "up arrow" key continually until your reach the lowest brightness level (9). Press the "down arrow" key continually until you reach the highest brightness level(0). Use the "up arrow" key and the "down arrow" key to set the brightness level that you find provides the right level of brightness for your work.
