I have replaced the batteries thinking that they were the reason that it won't come on, but after replacing the batteries it still will not come on. What should I do to get the calculator to turn on or it something wrong with the calculator that can't be fixed?

Re: my ti-89 will not come on
Check to be sure the battery contacts are actually touching the batteries. You might try bending them in toward the batteries (or stretching the spring a bit (if they are that kind of contact - I can't remember). Also be sure you are using good replacement batteries (sounds silly I know, but sometimes you get a dud).
If it still doesn't come on you might want to try opening it up and looking inside (can't hurt - it's not working anyway, right?). Sometimes, because of a drop, a part might have come loose and can be resoldered or there might be some other visible problem. (My daughter's TI-83 had a little coil that had broken loose after she dropped it, and it was a simple repair.)

I think the blue line is generally unfix-able without replacing the screen, which costs as much as a new calculator. The freezing may be fixable, try taking out the triple A batteries and leaving the calculator to sit with them out for a minute or so, replace them and check if it's fixed. If that doesn't work you can do the same but take out the small button back up battery as well. If you're still not having luck you should call ti cares (800-842-2737) they're usually helpful.
1. Remove 1 AAA Battery 2. Press and Hold 'ON' for 30 seconds 3. Replace AAA Battery 4. Adjust Contrast to appropriate level
If this fails, try again with ALL Batteries removed including the backup Lithium Battery.
If all else fails, try the following reset procedure:
1. Remove ALL Batteries (inc. Backup) 2. Let Calculator sit with no batteries for 2~4 hours. 3. Hold 'ON' for 30 seconds. 4. Replace all the batteries (May be good idea to use new batteries just in case old ones were dead) 5. Turn on Calculator 6. Change Contrast to appropriate level
- Remember to use correct batteries or calculator may not work. The correct batteries are Alkaline, Rechargable Batteries are TOO WEAK, Heavy Duty batteries are TOO STRONG.
The only option or keys that will work is the ENTER key and the arrow keys. Try to get your arrow key to work by arrowing down and hit enter hopefully change you to something different. Next, if at all possible can you hit the MODE key or get into the mode. If you get into the MODE select F3 and then arrow down twice or all the way to the bottom and at APPS Desktop select 1:OFF and then hit the ENTER key. Next, What I really think you need to do is reinstall the Ti 89 OS software. To do so you would need to connect to your computer or another Ti 89 Titanium to your Ti 89 Titanium. If you have Ti connect computer software (from the Ti site) connected to your Ti 89 Titanium it might help you more in troubleshooting any further problems too. You might be able to delete corrupt files that would free your calculator up and start running better.
If you download games and some third party software can be running all the time draining your batteries. Some of the APPS with Ti 84 will do the same thing. I'd try and find the problem software and delete it.
Please don't get your hopes up, but perhaps something in the following few suggestions will work:
For the TI-89 Family, TI-92 Family, and Voyage™ 200:
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.
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.
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  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.
To reinstall the Calculator's operating system, take a look at the following TI site.
Try doing a hard reset (hold simultaneously Left + Right + 2nd + On). If it just isn't wanting to display properly, but does turn on, that might help. I think you can do the same thing by taking the four AAA's out and the spare CR1616/CR1620. Otherwise, the battery acid probably ate one of your components and it's time to repair/replace your handy-dandy.
