I have a TI 89 but when I turn it on the screen is totaly black after waiting like 10minutes or so it started to brighten.

Try adjusting the screen contrast. Turn the calculator on. Press and hold the diamond key, then press + to darken or - to lighten the screen.

My TI-89 Titanium's screen froze. Well actually, the cursor kept blinking but none of the buttons worked. I got it to restart using the (-) and ) button trick, but rather than going back to normal it went...

Hi kelsers,

You need to re-install your calculator's OS. After this process your Ti 89 Titanium will operate properly. If you do the process below make sure you use new batteries.

Warning!!! If you do this procedure make sure that your computer and, calculator are connect. Use Ti Connect software and, make sure you can install the OS on the calculator without any interruption. At any time even at the very beginning of this process, if your computer or, calculator gets interrupted or you have a power failure during the installation of the OS, your calculator will be destroyed. So not attempt this procedure during a thunder storm.

You can use the Ti OS Downloader but, you will have no idea what OS is stored by the Ti OS Downloader. So, I suggest following my instructions and, installing the newest Ti 89 Titanium OS 3.10v.

Procedure to installing the newest Ti 89 Titanium OS 3.10v.

You can also get the latest copy of Ti 89 Titanium OS 3.10v by going to the Texas Instruments web site. You can get to that site instantly by clicking, "Ti 89 Titanium OS 3.10v." Once your at the Ti site click the Download Item, Ti 89 Titanium OS 3.10v. Next you can login or, click "continue as guest". I'd would click the "continue as guest". Once you have click, "continue as guest" the Ti 89 Titanium OS 3.10v. will download to you. Click, "SAVE". And then a folder will pop up. It is probably a folder that you download too. If so, you may want to change it and, "Save as" to this folder, "My Documents \ My TI Data \ Downloads". You can also go back and, download the Ti 89 Titanium guidebook too, if needed.

Link your computer and calculator with the USB cable or, Direct Black Link cable that came with the calculator.

Remove one of the AAA batteries. Press and hold the [APPS] key, and while holding the [APPS] key, replace the battery and turn the unit on. On the older TI-89 you should see "Press I to install code...", and you should press the [9] key to continue. But, on your Ti 89 titanium it should say, "Waiting to receive..." or, "Waiting to received OS...". Now you need to follow the instructions in the paragraph below to restore the calculator's operating system.

Next, drag the Ti 89 Titanium OS 3.10v. that you copied earlier to "My Documents \ My TI Data \ Downloads" out of that folder and, drop it in the "Ti Connect" icon on the desktop. Next the OS Downloader Warning will pop-up. Click, "OK" to continue and, the new OS will begin to install. The Ti Device window should pop up and, click on to the port where your Ti 89 Titanium is located, USB1 cable or Direct Black COM1. Just click, "Select" and, the OS will continue to download. Upon completion the newest Ti 89 Titanium OS 3.01v. will be installed.

My TI-89 wont turn of even after I've changed the batteries twice and switched the batteries around in the calculator. occasionally, i switch the battery placings and it turns on but now it refuses to...

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. Turn the calculator on (or at least press the ON key). Press and hold the diamond key. Press and hold the + key for a few seconds and see whether the screen becomes legible.

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

your contrast might be up to much.
try this:

hit the diamond key and then the minus key. this shoud decrease the contrast. keep reapeating these same steps until your home screen is visible. hitting the diamond key, then the plus key turns up the contrast.

Screen is half Black

The ribbon cable that controls the screen is damaged (or the liquid crystal has baked out... tis happens when the unit is exposed to high temps or long periods of direct sunlight). From my experience w/ these calculators they cannot be repaired.

Half the screen on my TI-89 is black

Hey, i have nearly the same problem and now finally found a solution to it. In my case half of the screen was empty and the other worked correctly AND slight pressure to the frame surrounding the display on the side of the defect half and/or above the display makes the display reappearing again. Because it's annoying if you always have to press with one hand on your calculator while working with it i did the following: Important: Make sure that... ... you have a backup of the data stored on your TI because you could lose them during the following procedure. ... we are really talking about the same problem. ... this hints come without any warranty and you might destroy your calculator completely following this advice. 1. Open your TI 89 as described for example in [1] 2. Take a piece of foam rubber and cut out a stripe with a shape like |_ or "L", about 1cm in width which fits approximately the frame around the display on the the defect side and the top. 3. Place the foam rubber on the silver shield you see after opening the back of your TI. 4. Then you can assemble your calculator again. I hope i could help you! [1]
