SOURCE: I tried updating the OS on my TI-89 Titanium

There is a progress bar while downloading and installing the OS
if it doesn't go away and you can't use your TI then you can re-install the OS
When you do re-install the OS just re-download a second copy from the Texas Instruments
website and use that. Do not unplug the calculator until you see the normal homescreen and everything is fully working again.

SOURCE: When I turn the switch on, ti-89 titanium does not turn on.

If you connect calculator to computer using Ti connect device explorer you might be able to see what files are on the calculator. I don't know if you downloaded from the web but, 3rd party programs and shells tent to miss up the calculator. This would able you to delete out possible problems which could be re installed later.

You have a older Ti89 /Ti83 APP or software on your calculator that you have to have a key, a proper serial number and a certificate in order to run on your calculator. Like my calculator has certificate #19 which allows me to operate a certain APP that is not issued any more. You need to get rid of that APP or software and update it with the new version. Obviously, you did not just download this recently from Ti89 \ Ti83 or Calculus Made Easy. This should give you a clue to what you did wrong. I don't think Nils at Calculus Made Easy or Ti89 \ Ti83 will give you a certificate but, they will help you with your software needs. K24674 instruction to you on how to reinstall the OS v2.09 for Ti89 is correct. Just don't try reinstalling the APP's or software that you had on the ti89 \ Ti83. Go to the Ti89 \ Ti83 APP's and programming sites and download and install the new updated versions of those APP's and software for your calculator.

The screen on my TI-89 Titanium turned blue after replacing batteries? How do I fix this? It turns on and off but does not respond to any other buttons.


If you cannot see anything on the screen, you may need to adjust the graphing TI 89 Titanium calculator contrast :

1.To darken the screen, press and release 2nd key, and then press and hold up-arrow key until the display is sufficiently dark.

2. To lighten the screen, press and release 2nd key, and then press and hold down-arrow key until the display is sufficiently light.

I cant really read some of the options on the screen on my ti 89....the letters are so blurry......what can i do ?????


Hey shrestha,

I've never seen a calculator with display clarity problems.

The only option I could think to offer you is to attempt to adjust the contrast. However, I'm not sure whether or not your TI-89 actually has an option to change the contrast. Because I own a TI-89 Titanium - and although its a wonderful calculator - it does not allow the user to alter the darkness/brightness of the display.

Call Texas Instruments: 1-800-TI- CARES...They are pretty helpful with common questions like this.

Sayonara,
