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,

Hi, I recently purchased a ti 89 calculator from a friend and I am having the following problem: The calculator will not evaluate trig functions. For example, if I type Sin(Pie/4) and hit enter, the...


The calculator is set up to produce exact results. If you want the expression to be evaluated put a decimal mark at the end of the 4.
to making 4 a floating point number instead of integer.
Alternatively, press the [MODE] key. Scroll down through the pages of options until you reach the line labeled Exact/Approx. When cursor is on that line, use the right arrow key to open the menu. Select [3:Approximate]. Press [ENTER] to save.

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.

When I turn on my calculator, there's a 2mm dark line running across near the bottom of my screen??!?!


Hello,
If it looks like the one in the picture (disregard the symbols) that is normal. The content of the command line (remnant of the last command line) is highlighetd so that you clear it at the push of one button.

Changing the Cursor Appearance


I had this same problem on my TI 89... You must have accidentally set your calculator to insert mode. To switch it back to the thin cursor, input the following keystrokes... Go to the "2nd" key to enter second function mode. Then press the button with an arrow on it pointing to the left(The key that you use to backspace). Do you see the "INS" lettering above the backspace key? There's your solution :-)

Graphs


From the Y= editor:

1. Move the cursor to highlight the applicable function.

2. Select the Style menu and press 2nd F6.

3. Select the applicable style.

In this case you want Dot. The other choices are Line, Square, Thick, Animate, Path, Above, and Below.

For full details look in the section "Basic Function Graphing" in the TI-89 Guidebook.
