Press the 2nd key, and RELEASE the pressure.
Press the Up Arrow and HOLD pressure.
The screen contrast will increase. Release the pressure of the Arrow key when contrast is to your liking.

SOURCE: TI 84 Won't turn back on

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.

SOURCE: TI 83 Plus won't turn on after battery change

I was having the same problem...I found the info below on another blog and it helped me fix my calculator problem. Take out all the batteries, hold the DEL button and put the batteries back in (keep holding the DEL button until all batteries are put back in). This will restart the calculator and restore it to its default settings...but it makes it work again!

"Reflashing the OS is probably the thing to do now. I think there's some trick that throws the calc into OS receiving mode. Hold down DEL while putting the batteries in? I don't remember if that's it. Go to 1-800-TI-CARES/ti-cares@ti.com if you need specifics on getting the calc to take an OS upload given the state it's in."

My screen for my TI-83 is turning black and I can't get it off


How to Change the Brightness of the Display

To darken the display, press the yellow 2nd button and then press and hold down the Up-Arrow button located in the upper right section of the keypad. Release the Up-Arrow button when the display has reached the desired level of darkness.

To lighten the display, press the yellow 2nd button and then press and hold down the Down-Arrow button. Release the Down-Arrow button when the display has reached the desired level of lightness.

As you go through this process, a number will appear at the top right corner of the display. If this number is 7 or higher when your screen reaches the desired level of brightness, then your batteries are getting low and may need replacing soon. This number will be approximately 3 or 4 for new batteries.

The Texas Instruments TI-83 is a graphing calculator. It's aimed towards math and science students and lets them graph and compare functions, perform data plotting and perform analysis. It has an updateable memory for adding software applications. The device comes pre-loaded with applications too. An optional connectivity kit allows you to hook the device up to your computer, and there are also optional slide cases to protect it.
  • Turn on the TI-83. Press the On button.
  • Step 2Adjust the display contrast. Press and release the key marked "2nd" and then press and hold the arrow buttons, which are below and above the yellow half-shaded circle.
  • Step 3Go to the Home Screen. You can do this from anywhere. Just press the button marked 2nd and then Quit.
  • Step 4Perform a sample calculation to get the hang of how to use the device: Model flipping a coin 10 times. Track how many of those coin flips end up in a heads result and you want to do this simulation ten times. Press Math and the left arrow which will bring up the MATH PRB menu.

    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!
