Turn the calculator on. Press and release the 2ND key. Press and hold the down-arrow key until the screen lightens.

If you go too far, repeat the process using the up-arrow instead of the down-arrow.

Changed battery, still not turning on. what do i do?


The most frequent cause for this ''not turning on'' is a screen that is too light to see anything displayed. Try increasing the screen darkness.
Press 2nd key and release it
Press and hold the Up Arrow until it is dark enough.

If the does not work
  1. Press 2nd key and relese it
  2. Press UpArrow and release it
  3. Repeat the two steps until screen is dark enough.

I have a TI 84 plus silver edition. Won't turn


The problem may be due a screen that is too light to see anything on it. Adjust the screen darkness.
  1. Press [2nd] key and release it.
  2. Press and HOLD the [UpArrow] to draken screen.
  3. Release the [UpArrow] when screen is dark enough.
You can also connect it to the computer to see if TI Connect finds it. If it does, update the OS to version 2.53MP.

You change the backup battery if the calculator tells you RAM CLEARED each time you turn it ON.

I don't know how to unfreeze the calculator. When I turn it on, it goes to a graph screen that is completely black. When you press other buttons nothing appears. The blackened screen just stays there the...


Hello,

Press [CLEAR] to erase the screen.
Press [2nd][QUIT] to interrupt any program that may be hung in memory

Those steps were just in case. Even if these do not do anything keep hope. If you are lucky the screen may just be too dark.
Press [2nd] and release it.
Press and HOLD the Down Arrow, till screen lightens.

If that does not solve the problem you may have to force the calculator to boot up. Details are in the article . Read the part on Ti83Plus family.
The article contains links to additional articles.
Hope it helps.

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.

Calculator Stuck


Hi. I suspect your calculator BIOS is corrupted. Still looking for the download for that though. Do you have a USB link cable? If so, plug in your calc and check your device information. See if anything comes up.
