It may help to have the Brand and model of the calculator. But I suspect you pressed a Mode button, which gives you different configurations (modes of operations) for the calculator. If I guessed right you will have to enter a number between 0 and 3. If mode is not what you want, try a new number each time.

Hope it helps.

    If you have a MODE button, Press Mode and [2nd] or [INV] then DEC. it sets calculator to decimal (normal calculation.)

How to input numbers to solve a matrix using a casio fx-115es

Press MODE 6 to get into matrix mode. Note: do this only once. If you do it again, it will erase all your matrices. Pick the matrix, set its dimension, then the calculator will put up a screen allowing you to enter/edit the matrix elements. At any time you're in matrix mode, press SHIFT 4 to bring up the matrix menu.

All this is explained in the manual beginning on page E-57. If you've misplaced the manual, you can download a copy from

My 2000 prado radio gone off,has help on screen and a key symbol lit up


The radio is locked with the anti theft code.

This happens commonly when the car battery gets disconnected.

The anti theft code is printed in the booklet with car specifications (not the manual).

If you have misplaced the booklet, the easiest way to get this stereo unlocked is going to a car dealer and having the code calculated for a small fee.

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...

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 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

Hope it helps.
Thank you for using FixYa.
