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.

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-CARESemail@example.com if you need specifics on getting the calc to take an OS upload given the state it's in."

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.
