Turn on the TI 83 enter 1234
1. press the <2nd> once; press and hold the <up-arrow> until you get the numbers as dark as you want. If you let up and press the arrow key again you have turned the function off. You must start over by pressing the <2nd> key then the <up-arrow> key and hold.

2. If the numbers are too dark; press <2nd> once and hold the <down-arrow> to get it corrected.

3. If this does not correct the light/dark screen condition you need to buy new batteries!

Hope you can follow my explination.

How to get the screen to be darker


Turn the calculator on. Press and release the 2nd key. Press and hold the up-arrow key until the screen is dark enough. If you go too far, use the 2nd and down-arrow keys to lighten the screen.

I can only turn my calc. on, after that none of my keys work, i have even taken the batteries and changed them with out with no sucess of making it work, any idea how to fix it?


What does your screen look like? The screen could be manually darkened. Try pressing 2nd-Up to make the screen brighter, or 2nd-Down to make the screen darker. A common prank is to manually set someone's screen to be unnaturally dark or white.

My ti - 83 hasn't been used in a while, placed new batteries in it and all i get is dark screen.....it won't even turn off......there is just a dark screen......any ideas what causing this and how to fix...


The most probable cause (at least I hope so) is that the screen got too dark after you changed the batteries. It is a common occurrence: Screen becomes too dark or too light.
To adjust the screen contrast:
  1. Press ^2nd key and release it.
  2. Press and HOLD the DownArrow key until screen lightens to your taste.

After you change battery the screen contrast often changes: it can become too light or too dark (your case).
To lighten screen
  1. Press 2nd key and RELEASE IT.
  2. Press and HOLD the downArrow.
  3. Keep pressing the arrow until the screen is light enough.
