Question about Texas Instruments TI84Plus Graphic Calculator
The acid leak out from the AAA batteries, so I took the batteries out and replace with new ones. Then the TI is working fine. After using it, I remembered to remove the batteries. And then when I re-insert the batteries to use it, I am able to turn it on, just that I am not able to type anything. Then recently, I am unable to turn it on, even with the batteries replaced with brand new ones. Help!

the screen may be at the lowest dim setting, try turning it on, then pressing the 2nd key and then hold the up key and see if anything appears, if not let me know and I will try to figure out something else, I own a 83, 84, and 89 so it shouldn't be too hard to figure out

Hope is what keeps the world turning.
Clean the electrical terminals even if they seem shiny. Use a clean eraser tip of a pencil.
Insert the main batteries.
If you see the line again, press [CLEAR] to see if it disappears.
Try resetting the RAM by pressing [2nd][MEM][7:Reset][1:All Ram][2:Reset] [ENTER][ENTER].
If screen is too light or too dark, adjust the contrast:
Press [2nd] key and release it
Press and HOLD Arrow (UP to darken, or DOWN to lighten) the screen.
If that does not solve the problem you may have to force the calculator to boot up. Details are in the article . Read the part on Ti83Plus family.
The article contains links to additional articles.
Hope it helps.

Testimonial: "Thanks so much. The calculator is working now. It is so great to have someone who is willing to take the time to help. You guys are too cool."
SOURCE: I haven't used the calculator
Clean the battery damage up real good. Gently scrape to terminals of corrosion. Back in my day we use to put a little bit of coke cola to clean car battery posts to get a good connection. If you could put a little bit of coke on a Q-tip without getting any inside the calculator that would be good. Just let it soak in for about 30 minutes. And gently scrape the bad areas again clean of the corrosion. You have to clean it up to metal so, that when the battery is in it will be metal to metal connection.
If you can download new OS with another Ti83 Plus or, don't want to install the new OS goto Procedure 1.
Be ready to install the new ti 83 OS v.1.19. So, setup your computer with Ti Connect software and, have the new OS v.1.19 download ready and, in "My Documents \ My TI Data \ Downloads." If you need additional instructions on how to connect the computer to the calculator you can read my instructions at another posting I did. You can go to that posting by clicking, "Connection Instructions," under this paragraph. Just remember the OS was for a Ti 84 Plus and, your's is a Ti 83 Plus so, don't download the OS from the other posting. I'll give you a link below this paragraph to download the correct Ti 83 Plus OS v1.19 for your calculator here at your posting. Just follow the other posting to where I say, "You can also go back and, download the Ti 84 Plus guidebook too, if needed." After that statement the computer and, calculator get connected with the cable and, your not ready for that process, yet! When you come back to this posting and you have downloaded the new OS to the proper folder goto Procedure 1.
Additional computer to calculator connection instructions click, "Connection Instructions."
Ti 83 Plus OS v.1.19 download click, "Ti 83 Plus OS v.1.19". Save this download to "My Documents \ My TI Data \ Downloads".
Take all the batteries out for 10 minutes, including the very small one that you have to use a small philips screw driver to get it out. Watch out for the spring under the small battery, it might pop out. Replace all the batteries after 10 minutes with new ones, including buying a new small battery. The small one might cost about $5. I know it is expensive but, this might work.
A battery reset procedure should bring your Ti 83 Plus back to life.
Make sure the batteries are in correctly? The batteries alternate negative/positive, positive/ negative and so on. The first time I put the batteries in, I didn't have them in correctly. I know if it happen to me that anybody could make the same mistake. And of course, the calculator will never come on if the batteries aren't in correctly.
If your Ti 83 Plus turns on when you put the batteries back in you do not have to re-install the OS. I just think it is better since, your OS might be corrupt.
The process below should reset your calculator.
1). Pressing the [2nd] key followed by pressing and releasing the [Up Arrow] key. This adjust the contrast in case the contrast was to low. Keep repeating if necessary for about 10 seconds and, then go to the next step. If calculator comes on and responds to key functions your done. Once again, if your calculator turns on after this procedure you do not have to re-install the new OS. You can quit these procedures now with a perfectly good calculator.
Please be prepared to re-install the calculator's OS, if you run through this process.
2). 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". Connect to other Ti 83 Plus and, install OS from that calculator. Or, follow the instructions, I gave at the other posting "Connection Instructions" to reinstall the calculator operating system and, connect the computer and, calculator. You can start where, I say, "Link your computer and, Ti 84 Plus (Your's is a Ti 83 Plus) with the proper cable (USB or Black Link). Upon completion your Ti 83 Plus will be ready to use and, the new OS installed.
