If nothing is visible on the screen, increase the contrast by pressing and releasing the 2ND key then pressing and holding the up-arrow key.

If the screen is visible but you get no response to the keys, press and hold the 2ND, left-arrow, and right-arrow keys, then press and release the ON key.

If this doesn't do it, please add a comment to this post and we'll go on from there.

Hello, my name is Lucas Matthews and I have a TI-89 that is frozen. The home screen is frozen and wont change. I have tried taking out the batteries and replacing them. Also, I have tried holding the ON...

There is a backup battery hidden under a cover in the battery compartment. Try removing all the batteries, including that one. Wait a little while, then put them back in. While you're waiting, apparently dust in the usb connector can cause problems. I don't know why, but it can't hurt to clean it out if it's dirty. If that fails, you can plug it into your computer, download the necessary software from the TI website, and reinstall the OS. If all that doesn't work, there might be a hardware problem.

My ti-89 screen is frozen and wont accept input

Remove the batteries and wait a minute or two. Put them back in and turn the calc back on and it should function normally. Check for stuck buttons as well, as sometimes they will cause the calc to appear "frozen".

All buttons on my TI 84 are frozen

TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on at all. 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.

Screen frozen

When you turn the machine down, it rests where you left it, in the state you left it: In case you wanted to continue with the same program, what you have already accomplished will not be lost.

After you turn it on, Press [2nd][QUIT] or just press the [HOME] button, and it will take you home.

Hope it helps
