Question about Texas Instruments TI-83 Plus Calculator

1 Answer

Random screen My son gave me his TI83 after not using it for over a year. We replaced the AAA batteries. It is powering up but a series of vertical lines or a blinking horizontal line appears on the top or the middle of the screen. A couple of times pressing "clear" several times corrected the problem, but generally it really is not usable. Any suggestions?

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 own a TI-83 Plus that just quite one day. I replaced the battery and still nothing. The display never recovered. Between my son and daughter and I this is the third TI-83 Plus that has had power circuit...


Hello,
When you change the batteries the display reverts to default setting. My optimistic guess is that the screen display is so light that you cannot see anything on it. This can be arranged.

A Try this before thinking of repairs.

  1. Push the ON button.
  2. Even if you see nothing, press the [2nd] key and release it.
  3. Press and HOLD the UpArrow key until the screen darkens.
  4. You may have to keep pressing UpArrow for a little while before you see anything.
B If that does not work
  1. Remove one of the AAA batteries.
  2. Press and hold the [CLEAR] key.
  3. Whileholding [CLEAR], reinsert the AAA battery and then
  4. turn the calculatoron.
  5. The calculator should display the message "RAM Cleared".
  6. Release the [CLEAR] key and then press it one more time to remove the message "RAM Cleared".
C. Third option

  1. Remove batteries including the backup battery for 5minutes.
  2. After the 5 minute period, reinsert all of the batteries and
  3. turn the calculator on.
  4. Adjust the contrast if necessary.
D. Last option

The last option requires the reinstallation of the system. So to use it you must download the TIConnect 1.6 software from education.ti.com. You must have the TI USB SilverLink or the TI Black serial cables ready.You must be connected to the Internet.
  1. Remove one of the AAA batteries.
  2. Press and hold the [DEL] key.
  3. Whileholding [DEL], reinsert the AAA battery and then
  4. turn the calculatoron.
  5. The calculator should display "Waiting...Please install calculator software now".
  6. Connect the TI Connectivity cable between the computer and the calculator.
  7. Click on Start >> Programs >> TI Tools >> TI Connect >> TI OSDownloader.
  8. 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.

If all else fails you can contact Texas Instruments at ti-cares@ti.com

Hope it helps.
Thank you for using FixYa.

Hello,
The answer I gave you was taken verbatim from the TI FAQ and knowledge base. I copied and pasted the part relevant to you calculator.
In any case, I sent an e-mail message to ti-cares@ti.com, giving the link to your original question and my answer to it. I took the liberty to copy/paste your present message. I also asked about that invalid certificate.
All we can do know is wait for their reply.

Turn-on woes My TI83 will not turn on. Batteries new and installed correctly. What gives? Khumalo


Take out the AAA batteries and hold the on/off key for thirty seconds. Replace the batteries and it should come on. If it doesn't remove the backup battery and the AAA batteries and hold the on/off key for another 30 seconds. Replace all batteries and turn it on again.
