I tried furiously blowing in to the back of mine with all 4 AAA batteries and the back up battery removed
then i left the batteries out for 2 days
it works again with really minimum use... you have to repeat the blowing and leaving out nonsense every week
sometimes you regain use by rubbing the AAA batteries back and forth while they're in place

better get a new one if you can afford it

My TI-84 Plus Silver Edition is frozen. I can't clear the screen or enter in another problem. What do I do?


If the TI-84 SE does not function even though you are sure that the
batteries are fresh, you can try manually resetting it by following steps:

1. Remove all of the AAA batteries from the graphing handheld

2. Press and hold the ON key for ten seconds

3. Replace the batteries

4. Turn on the unit

When you reset your graphing handheld, the contrast sometimes
changes. If the screen is faded or blank, adjust the contrast by
pressing 2nd and releasing up-arrow or down-arrow keys.

Screen frozen with ans+ and blinking cursor new batteries...both kinds blew air into the I/O port tried the key combinations clear & del with batteries and nothing works


Hopefully this will get you around the problem for the time being. You can download a program called "Virtual TI" written by Rusty Wagner. You will also need to download the TI-84 ROM file from the Internet and place it in the folder with the Virtual TI program.
Once Virtual TI is running, press F12 and select the version of the calculator ROM that you have. You can also try WabbitEmu.

I have a TI-84 plus silver edition. there was a notice on my screen saying that batteries were low. I replaced them, and when I turned it back on, the RAM was cleared, but the screen acted like it was...


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 that isn't it, then remove all four AAA batteries. Press and hold the ON key for ten seconds. Replace the batteries and turn the calculator on. (You may have to adjust the contrast as described above.)

I have a TI 84 plus silver edition. Won't turn


The problem may be due a screen that is too light to see anything on it. Adjust the screen darkness.
  1. Press [2nd] key and release it.
  2. Press and HOLD the [UpArrow] to draken screen.
  3. Release the [UpArrow] when screen is dark enough.
You can also connect it to the computer to see if TI Connect finds it. If it does, update the OS to version 2.53MP.

You change the backup battery if the calculator tells you RAM CLEARED each time you turn it ON.

All buttons on my TI 84 are frozen


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.

TI-84 Calc is FROZEN


I'd try hooking it to the computer using ti connect explorer and see if deleting the programs there would help. I had a calculator that did the same thing and never did fix it. But if your memory can be delete and reinstalled it might work.

RAM Cleared


This is kinda a weird situation. Because it's usually the other way around. Your ram will clear if your calculator is frozen. So take out all 5 batteries from the back. Even the back up battery. Then reset it again. 2nd then + then 7 then 1 Then 2. Good luck.
