TI 83 Plus Calculator

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. 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.

If the screen remains blank then please respond to this post and we'll go from there.

If you cannot see anything on the screen, the contrast may need to
be adjusted.
To darken the screen, press 2nd and release, and then press and
hold up arrow until the display is sufficiently dark.
To lighten the screen, press and release 2nd, and then press and
hold down arrow until the display is sufficiently light.

Reinstalling the OS fot the TI84Plus

Howdo I correct the Error Waiting...Please Install Calculator SoftwareNowmessage 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.Themost common cause of a transfer being interrupted is updatingthe operating system on a calculator with low batteries. Users will needtouse the TI Connectivity cable and the TI Connect to sendthe operating system to the calculator. Make sure to have thelatest version of TI Connect 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.
If themessage "Error! Press any key to turn unit off. Then turn unit back on."appears on the graphing calculator, quickly, remove one battery from thecalculator and reinstall it while the transfer is taking place.

Hello,
Well, if screen shows the RAM CLEARED message, that means your calculator is working. Just press the [CLEAR] key, message will be erased and you are ready to crunch numbers.

Hope it helps.

Hello,
The liquid crystal is damaged. I suppose the screen can be replaced. Check with Texas Instruments resellers (usually academic bookstores): they may be able to tell you where you can have the calculator serviced.

OK for batteries to be dead
But calculator must be alive.

Hope it helps.

Hello,
I have just done what you said you had done, but I got a nice, correct table of values. You might have discoverd a secret command to clear memory.

Cheers.
