    Press and hold the 2ND, left-arrow, and right-arrow keys, then press and release the ON key. Does this do anything?

  • kit88chocola Sep 11, 2010

    no it didn't work

  • kit88chocola Sep 11, 2010

    no it didn't work =/

  • kit88chocola Sep 11, 2010

    okay now my calculator says address error....

  • kit88chocola Sep 11, 2010

    okay now my calculator says address error....

  • kit88chocola Sep 11, 2010

    now it says Address Error, and it shows the man and rad auto and 0/30 thing at the bottom but wont let me type or anything, all i can do is press 2nd or the green diamond button

  • kit88chocola Sep 11, 2010

    main*

  • kakima Sep 11, 2010

    So the other keys do nothing? Pressing APPS, for example, doesn't bring up the apps menu?

  • kit88chocola Sep 11, 2010

    nope, it still just says address error. the 2nd, diamond, arrow, and alpha keys work but nothing else

  • kakima Sep 11, 2010

    I'm getting stumped...

    What happens if you try the 2ND, left-, and right-arrow keys now? If that doesn't work, go on to the (-) and ) part.

  • kit88chocola Sep 11, 2010

    when i press that it resets, takes a while for the address error to come back up, and the same thing happened w/ the (-) and ) thing .... srry that you're getting stumped =/

  • kit88chocola Sep 12, 2010

    all i can see are the diamond button the alpha button the 2nd button and the diamond button other than that, all thats on the screen is adress error

  • kit88chocola Sep 12, 2010

Try resetting the calculator. Remove all four AAA batteries. Press and hold the ON key for ten seconds. Replace the batteries and turn the calculator on. You may have to adjust the screen contrast again.

It has been awhile since I've used my TI 89. It will not turn on and when I removed the batteries there was some dry build up around the ends of the batteries and along the surface. I wiped the surfaces...


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 release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

If this doesn't do it, remove all four AAA batteries. Press and hold the ON key for ten seconds. Replace the batteries. Does the calculator turn on now?

TI 89 won't turn on


Try a hard reset if you're willing to sacrifice the contents of all RAM.

1. Make sure the batteries are installed correctly.
2. Press and hold the 2nd, Left, and Right keys.
3. Press and release the On key.

Voyage 200 won't turn on


I've fixed my Voyage 200!! I fixed it using the 3rd solution listed below. I've placed them all in there in case the one I used din't work. The funny thing is the solutions listed weren't even for the Voyage 200. I mistakenly tried the wrong one, but it worked!! I've also posted some soultions listed for the Voyage 200 just incase the others don't work and the website I found these solutions can be found here. Good Luck!!

Website:
http://epsstore.ti.com/OA_HTML/csksxvm.jsp?nSetId=85103&nUsePub=NO&jttst0=6_23871,23871,-1,0,&jtfm0=&etfm1=&jfn=ZG1C0B48595DC76138EFAD7BAC9C1E63B698A69C9FCFEA6C84DEE9934631AC138649F2CD10EBEEF5C5E390C0B8C5F215C2F3

List of solutions that worked for me:

  1. Try a new set of batteries (including the backup battery).
  2. Adjust the contrast by pressing and releasing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. To adjust or lighten the display, use the down arrow.
  3. Remove one of the AAA batteries. Press and hold the CLEAR key. While holding CLEAR, reinsert the AAA battery and then turn the calculator on. The calculator should display the message "RAM Cleared". Release the CLEAR key and then press it one more time to remove the message. (worked for me!! Never actually said "Ram Cleared" just had a long box across the screen that filled up and POOF it was back!!)
  4. Remove one of the AAA batteries. Press and hold the DEL key. While holding DEL, reinsert the AAA battery and then turn the calculator on. The calculator should display "Waiting...Please install calculator software now". Follow the instructions for the TI-83 family or TI-84 Plus family to reinstall the calculator operating system.
  5. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.
Voyage Solutions:

For the TI-89 Family, TI-92 Family, and Voyage™ 200:
  1. Try a new set of batteries (including the backup battery).
  2. Adjust the contrast by pressing and releasing the Diamond Key key followed by pressing and releasing the [+] key; repeat as necessary. To adjust or lighten the display, use the [-] key.
  3. Users of the TI-89 Titanium or Voyage 200 should see the following case before performing the following reset procedure to prevent the loss of valuable Apps.
    On the TI-92 family or Voyage 200, hold the [2nd] key and the [hand] key, then press and release the [on] key. On the TI-89 family, press and hold the [2nd] key, left arrow, and right arrow; then press and release the [on] key. This should reinitialize the operating system, in which you should see a progress bar filling on the screen.
  4. Remove one of the AAA or AA batteries. Press and hold the [APPS] key, and while holding the [APPS] key, replace the battery and turn the unit on. TI-89, 92 Plus, or Voyage 200 users should see "Press I to install code...", and should press the [9] key. The calculator should then say, "Waiting to receive...". TI-89 Titanium users should see "Waiting to receive..." or "Waiting to received OS...". You will need to restore the calculator's operating system.

HELP!!


Well, in most calculators, the action of taking out the backup battery practically clears the whole thing. Memory, everything. I myself have a Ti-89 and have not yet experienced this problem, but I have on an older Ti-82 and removed the backup battery and the whole thing is dead now, or at least nothing happens when I turn it on, even after replacing the batteries again. If you still have the manual, I would check out the troubleshooting. If you don't have it, try to find it online. And if you have done both of these things, try getting hold of technical support through Texas Instruments.

TI-84 will not trun on.


Try the following

1) Remove one of the AAA batteries, hold down on the DEL key while reinserting the AAA battery. The handheld might display Waiting…Please install calculator software now. Ignore this message. Remove and reinstall one of the AAA batteries again This time, do not hold down the DEL key.
2) Remove one of the AAA batteries, press and hold the [on] key for 10 seconds, release, replace the battery, then turn the unit on. Adjust the contrast.
3) Remove the AAA batteries for three hours. After the three-hour period, reinsert the batteries and turn the handheld on. Adjust the contrast if necessary.

If needed, reinstall OS by downloading the OS from the TI site and ....
On your computer, choose Start, Programs, TI Tools, TI Connect, TI OS Downloader.

(I am not the one who came up with this answer, but found it on an other site. If this doesn't work, please let me know)

My ti89 titanium doesn't turn on


I had the same problem. I changed the batteries and it didn't work. I took out the batteries for about 30 minutes, and then put them back in, and it turned on.
