    I put in new batteries, but the screen is dim, very hard to read. Help. I used copper top batteries. does this make a difference?

    I had the same problem. I did what Medinajaviersuggested (pressing the 2nd key, then pressing the up key, then pressing the 2nd key again and the down key), and it worked perfectly!! I thought I was going to have to buy another calculator!!

    Thank you soo much Medinajavier!!!!!!!!!!!!!!!

Adjust the contrast by pressing and releasing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. To adjust or lighten the display, use the down arrow.

Screen too dim


You can try adjusting the screen contrast by pressing [2nd] and using the up and down arrows. Up will make it darker and down will make it lighter/more faded.

I have had my ti 83 plus since fall 2005. recently the calculator has informed me to change the batteries. So i replace the backup battery and the main batteries. now it wont even turn on. Help.


The screen may be too dim to read. Try pressing 2ND->Up arrow key repeatedly while the calculator is turned on and it may darken the screen enough so you can read it.

The screen may be too dim to read. Try pressing 2ND->Up arrow key repeatedly while the calculator is turned on and the screen should start to darken so that you can read it.

My TI 83 Plus does not turn on. I have replaced the batteries and the backup battery. I have tried all the troubleshooting solutions given but still it does not turn on. What can I do now?


The screen may be too dim to read. Sometimes when the batteries are low, the screen automatically dims itself. The problem is, it doesn't undo that when the batteries are replaced. Try pressing 2ND->Up arrow key repeatedly while the calculator is turned on and the screen should start to darken so that you can read it.

TI 83 plus calculator has dim screen.


TI calculators have an annoying habit of dimming the screen when the batteries are changed. 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.

Hasn't been used for a while and now won't turn on...changed batteries


Very likely that the screen contrast changed after the replacement of batteries.Some times screen becomes too dark or too dim.
If it does not seem to turn ON that may be because screen is too dim that you cannot see anything and cannot be sure it is ON.

To darken the screen:
  1. Press the ON button
  2. Press [2nd] key and release it.
  3. Press and HOLD the Up Arrow.
  4. Keep at it until screen starts showing something.
