Question about Texas Instruments TI-83 Plus Calculator

1 Answer

Help! i found my TI 83 calculator in the calculus room on the last day of school. It worked for about 5 months, but now it will not turn on. I tried the thing where you take out a battery while pressing clear, but that didnt work, and i cant adjust the constrast. the AAA batteries are ok, but could i need a new backup battery, and, if so where do i get one?

An electronics store or Radio Shack should carry this. Take your old one with so that they can test it - it should be at least 3V. The battery type is CR1616 or CR1620

What is the different between ti-86 and ti-83

The 86 has more memory. It also has some advanced calculus capabilities the 83 doesn't. However you're much more likely to see examples for the 83 in textbooks and other references.

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 [email protected]

Hope it helps.

Can't turn on my new TI-83 calculator

Hello,
I cannot tell you why that happened (I am no prophet), I can just try to diagnose plausible causes. If it solves the problem, then my guess was good; if it does not then my diagnostics was wrong, and you should try other solutions.
My hunch is that the screen contrast has turned too light. The procedure to darken the screen is as follows.

1. Press the yellow [2nd] key and release it.
2. Press the [UpArrow] and release it.
3. Repeat Step 1 and Step 2 in sequence until the screen darkens, to your liking. You may have to repeat procedure several times. Main batteries must be good.

Hope it helps.

TI-83 Plus Silver Edition problem

These instructions are from education.ti.org, and worked for me.

1) Take out one of the AAA batteries
2) Hold down the CLEAR button
3) Put the AAA battery back in while still holding down the CLEAR button
4) Let go of the CLEAR button and turn the calculator ON
5) Press CLEAR to get rid of the error message.

Then you should be good! All the applications on my calculator were still intact, so despite the error message, the RAM was never actually cleared.

TI-83 LCD Screen Problem

Try replacing both the AAA batteries and the back-up batteries. This should probably fix the problem.
