When I turn on the calculator, I get a screen full of random black pixels. The AAA's and the lithium batteries are both good. Nothing I do will change the screen, except turning the calculator off.

Try to reboot your calculator to see if it helps by doing this:
*Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR], reinsert the AAA battery and then turn the calculator on. The calculator should display the message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message. *
Let me know if it helps or not.

    Nope, I tried that before, and again now - same result. I always get the black pixelated screen, and the only thing that affects the display is to turn it off. If you have any other suggestions, I will gladly give them a try. Thanks - ed.

    The other way to try is to erase the whole operating system and install it again. Do you have the cord to connect to the computer?

  • edworst Aug 22, 2010

    Yes, I have the USB cable. I'll give that a try. Thanks - ed.

  • TI-Book Aug 22, 2010

    You need a USB silver link cable or a serial link cable. If you have the USB version, install TI-connect on your computer. first. If you have serial link cable, install graph link software for it.

    If reinstall the software operating system won't fix the problem then follow this instruction:
    # Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator should display "Waiting...Please install calculator software now". Follow the instructions for the TI-83 family or TI-84 Plus family to reinstall the calculator operating system.

    Worked like a charm, THANKS!!!! Just got upset with my daughter for dropping it because it was buried in her backpack and fell to the ground when she pull a book out. She turned on the calculator and had a rectangle of black pixels. But now it is working!!!! Thanks to your instructions!

    I also tried to reset the memory twice, but the screen is still dark and non function in working. Unfortunately I don't have the cable to connect the calculator and i cannot reinstal the OS. I'll try to find the cable and try. thanks.

Wont turn on


Good morning, afternoon, evening or night; whatever time of day you are viewing this solution post. Thank you for choosing FixYa to assist you. You are having problems because you calculator won't turn on. I think you should try changing the batteries. Did you know that your calculator has two batteries powering it? Not only are the 4 AAA batteries powering it, but there is also a CR 3V Lithium Back Up battery powering it as well. First, try changing the 4 AAA batteries. If that still does not power your calculator properly, you will need to replace the lithium back up battery. You can find this at a department store or store that carries electronics. To do this, open your regular battery compartment. Above the AAA batteries is a compartment that says "BACK UP BATTERY CR1616 OR CR1620" with a picture of it. Use a small crosshead screwdriver to open the compartment. Take the old battery out and replace it with the new one. Rescrew the lithium battery compartment back on and close the AAA battery compartment. Turn on your calculator and see if that works. I hope this solution solves this.

My screen turns on but when you do anything it has random numbers, line and letters on it and i need to get it fixed immediatley


I've had this issue before with my TI-83 Plus. I'm not sure exactly the solution I used, but these steps progress through the mildest to most extreme methods of fixing the calculator.


Solution 1: Take the batteries out.

Odds are you've tried this already, but it bears mentioning.

With the calculator on, remove the triple A batteries housed in the back. After a few seconds, replace them and turn the calculator on.


Solution 2: Clear the RAM.

Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR], reinsert the AAA battery and then turn the calculator on. The calculator should display the message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message.


Solution 3: Reinstall the operating system

Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator should display "Waiting...Please install calculator software now"

Here is the website to reinstall your OS. First you'll need the TI-Connect software.


Solution 4: Remove all sources of power. This is a risky move, but if your calculator will absolutely not work after you try even reinstalling the operating system, it might be your last hope.

Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.

I have a TI-83 Plus. It just died. I have replaced the 4 AAA batteries and the lithium 1616 backup battery. I have checked to verify that the screen hasn't just dimmed. I get nothing. Any ideas?


Remove all four AAA batteries. Press and hold the ON key for ten seconds. Replace the batteries. Turn the calculator on (you may have to adjust the screen contrast again).

If this doesn't do it, please add a comment to this post and we'll go on from there.

I put new lithium triple aaa batteries in my TI-83. Nothing happened . days later it turned on worked for a little while then stopped. would it help to change the round lithium battery? Do you know what...


The button cell backup battery keeps the memory electrically refreshed when the calculator is turned OFF. The necessary power for regular use is supplied by the 4 AAA batteries (main power). That nothing happened when you put in a fresh set of (expensive) lithium batteries may be due to the screen being too dim to see anything.

If the calculator displays RAM CLEARED each time it is turned on, it may be due to a depleted backup battery. The battery model number is CR1616 or CR1620. On my TI84PLUS the backup battery is of type 303 (Sony) or SR44SW (Maxell).

Screen fully black


Black-Screen/Black-Pixel Fix for TI-Calculator

This will erase all memory and reset defaults.

1. Remove 1 AAA Battery
2. Press and Hold 'ON' for 30 seconds
3. Replace AAA Battery
4. Adjust Contrast to appropriate level

If this fails, try again with ALL Batteries removed including
the backup Lithium Battery.

If all else fails, try the following reset procedure:

1. Remove ALL Batteries (inc. Backup)
2. Let Calculator sit with no batteries for 2~4 hours.
3. Hold 'ON' for 30 seconds.
4. Replace all the batteries (May be good idea to use new batteries
just in case old ones were dead)
5. Turn on Calculator
6. Change Contrast to appropriate level

- Remember to use correct batteries or calculator may not work. The
correct batteries are Alkaline, Rechargable Batteries are TOO WEAK,
Heavy Duty batteries are TOO STRONG.
