Hello,
No offensee meant, but you may have used the procedure to darken contrast incorrectly
1. Press [2nd] key and release it
2. Press [ArrowUp] and release it
3. Repeat steps 1 and 2 in sequence until screen is dark enough.

If you want to lighten it: in step2 press [DownArrow].
Should this procedure fail, you may have to replace the main batteries.

Hope it helps.

My TI-83 plus calculator doesn't work


As battery gets drained, the screen contrast dims. But when you change batteries, some times the contrast is reset to some low value and the screen appears dead: it is so light that you do not see anything, and you think the calculator is malfunctioning. This is the most frequent reason users think the calculator refuses to turn ON. And I hope that is the case now.
To correct that, you must increase screen contrast: draken the screen a bit. To do so
  1. press [2nd] key and release it.
  2. Press the Up arrow and HOLD pressure.
  3. Keep pressing the arrow key until screen is dark enough.
If that solve your problem that is good, rate the post accordingly.. If that does not, do not get irate and berate the post. Post a comment here describing what you did and what message (if any) calculator returned, and I will give you further diagnostic steps.

TI-83 screen is black


The "color" on your screen reset to dark. You can adjust it by pressing "2nd" and the "up" arrow (or "2nd" and "down" arrow) repeatedly.

I accidentally pressed down for too long on my ti-84 plus calculator and i think it locked itself. how can i turn it back on? I NEED it for school!


From TI FAQs:

What troubleshooting can I try if the TI graphing calculator will not turn on?

For the TI-83 Plus Family, TI-84 Plus Family:
Caution: The resets described in these troubleshooting steps will cause a loss of applications, programs and data. If at all possible please create a backup using TI Connect™ first.
  1. Try a new set of AAA batteries.
  2. 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.
  3. Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR], reinsert the AAA battery and then turn the calculator on. The calculator should display the message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message.
  4. Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator should display "Waiting...Please install calculator software now". Follow the instructions for the TI-83 family or TI-84 Plus family to reinstall the calculator operating system.
  5. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.

Ti 83 plus small black screen?


try pressing 2nd then hold in down arrow to change the contrast

TI-83 countdown


Pressing 2nd then the up or down arrows is how you change the contrast on the TI-83. All you need to do is press the 2nd key then hold the down arrow to get your screen back. The countdown that you saw was just the value the calculator assigns to the contrast. It goes from 0-10.

Hope that helps!

You should press the 2nd and then hold the down arrow to cahnge the contrast. If that doesn't work then you should try resetting the calculator by taking both the back up and main batteries for 45 seconds.
