    my calculator has been used frequently but today I tried to turn it on and jumbled images came on my screen. I changed the batteries and the problem is the same.

    same thing i will do a few things and small parts of what i did will be left on the screen like a minus sign or pat of a number

    Same thing happened to me. I bought my TI-83 Plus about 5 years ago, used it only a handful of times, then stored it away. I took it out just today to check on it, and my screen is garbled and pixelated and when it scrolls it becomes illegible. I have replaced the batteries but NOT the backup battery. Yet. I will replace the backup later today, see if that helps. I am so pissed off over this; I bought that TI and only used it a couple of times. Someone please help!

I think you may have an app that is interfering and running when it shouldn't. I'd try deleting or reset the calculator. When you put things back on don't do everything at once. A little at a time until you find out which is giving you problems. raklein62@yahoo.com

    If you have a lot of the memory used up or installed 3rd party shells and programs to the calculator (Good chance it would work as advertised). Now I give good instructions to follow that can be downloaded by email. And since no one has emailed me for them you guys can stay in La! La! land.

Ti 83 will not power on replaced all batteries


When you clear memory, the contrast sometimes changes. If the screen
is faded or blank, adjust the contrast by pressing 2nd and up- arrow or down- arrow keys .

Resetting RAM restores RAM system variables to factory settings and
deletes all nonsystem variables and all programs. Resetting defaults
restores all system variables to default settings without deleting variables and programs in RAM. Resetting RAM or resetting defaults does not
affect variables and applications in user data archive.
Tip: Before you reset all RAM memory, consider restoring sufficient available
memory by deleting only selected data.
To reset all RAM memory or RAM defaults on the TI-83 Plus, follow these
steps.
1. From the RAM ARCHIVE ALL menu, select 1:ALL RAM to display the
RESET RAM menu or 2:Defaults to display the RESET DEFAULTS menu.
2. If you are resetting RAM, read the message below the RESET RAM
menu.
• To cancel the reset and return to the home screen, press .
• To erase RAM memory or reset defaults, select 2:Reset.
Depending on your choice, the message RAM cleared or Defaults
set is displayed on the home screen.

I have attempted to transfer an inequalz app from on TI 84 plus calc. to another TI 83 plus via the black serial cable. I get the following on the screen of both calculators. ERR:memory 1:Quit 2: Goto...


The problem may be due to a lack of memory in the receiving calculator. Check size of the Inequalz application, the size of the archive memory left on the TI83 Plus, and the number of application spaces that Inequalz requires. An application may require 1,2 or more application spaces. You will have to go to education.ti.com to get the information.
Also, make sure that the batteries are good in both calculators.

We have a Ti83 Plus Silver Edition we bought around 10 years ago for my daughter. My son is now using it and it goes through fresh AAA batteries in a matter of a day or two. It works fine otherwise, what...


If i were you since it goes through batteries so fast i would either buy some of the electronic batteries that are supposed to have super long battery lives but cost more or i would buy rechargeable batteries so that i wouldn't have to go out to the store and keep buying new batteries.

I have a TI83 Plus . Its been inactive for over year. I replaced the 4 AAA and the CR battery. The unit will not start. It does nothing. What can I do?


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 at all. 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.

I changed the batteries and now it will not come on


Hello,
Here it is from the horse's mouth (TI Knowledge base)

For the TI-83 Plus Family, TI-84 Plus Family:


Caution: The resets described in these troubleshooting steps will cause a lossof applications, programs and data. If at all possible please create backup using TI Connect™ first.
  1. Try a new set of AAA batteries.
  2. Adjustthe contrast by pressing and releasing the [2nd] key followed bypressing and releasing the up arrow; repeat as necessary. To adjust orlighten the display, use the down arrow.
  3. Remove one of theAAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR],reinsert the AAA battery and then turn the calculator on. Thecalculator should display the message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message.
  4. Removeone of the AAA batteries. Press and hold the [DEL] key. While holding[DEL], reinsert the AAA battery and then turn the calculator on. Thecalculator should display "Waiting...Please install calculator software now". Follow the instructions for the TI83 or TI 84 Plus family to reinstall the calculator operating system (see below.)
  5. Removeall of the batteries including the round lithium battery for 5 minutes.After the 5 minute period, reinsert all of the batteries and turn thecalculator on. Adjust the contrast if necessary.

Reinstalling the OS for the TI83/TI84 Plus family

How do I correct the Error Waiting...Please Install Calculator SoftwareNow message on my TI-83 Plus family or TI-84 Plus family calculator?

If an operating system (OS) update fails or is interrupted, the calculator will be in an inoperable state with the message Waiting...Please install calculator software now.The most common cause of a transfer being interrupted is updating theoperating system on a calculator with low batteries. Users will need touse the TI Connectivity cable and the TI Connect software to send theoperating system to the calculator. Make sure to have the latestversion of TIConnect installed on the computer.
In order to install the software please follow these steps:
1. Connect the TI Connectivity cable between the computer and the calculator.
2. Click on Start >> Programs >> TI Tools >> TI Connect >> TI OSDownloader
3. Follow the on-screen directions to reinstall the calculator's OS.
Ifthe message "Error! Press any key to turn unit off. Then turn unit backon." appears on the graphing calculator, quickly, remove one batteryfrom the calculator and reinstall it while the transfer is taking place.

Hope it helps.
