You can use the calculator with it on the screen; the indicator simply tells you that it's in a fixed-decimal setting. To remove the fixed-decimal setting, press FIX . (decimal point).

My ti-89 screen is frozen and wont accept input


Remove the batteries and wait a minute or two. Put them back in and turn the calc back on and it should function normally. Check for stuck buttons as well, as sometimes they will cause the calc to appear "frozen".

Ti-83 plus silver edition. calc won't turn on.


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.

Ti 84 not working


Hello,
Since it gets tossed around a lot, it is possible though improbable that the batteries lose contacts with the electrical terminals.
You may try to darken the screen a bit.
1. Press [2nd] key and release it
2. Press [UpArrow] and release it.
3. Repeat steps 1 and 2 in sequence until contrast is satisfactory.

If that does not fix the problem, use a calc-to-calc cable and try sending something to it from a working calculator.

You can also download the TIConnect software from education.ti.com and install it on your computer. Then connect the calculator to the computer by means of a USB cable, a TISilverCable, or a TI Graphlink (Black cable). Turn the calculator ON, run TIConnect, connect calc-to-computer and Click TIDEVICEINFO in TIconnect main window.

If it tells you NOT FOUND, on any of the ports, click the communication settings: Set the device type to you calculator model. Set the cable type. Set the port (COM x) or USB1
If calculator is not detected through any of the available ports (COM ports, or USB), then it would suggest that calculator is in need of repairs.

Hope it helps.

TI 83 Plus won't turn on after battery change


I was having the same problem...I found the info below on another blog and it helped me fix my calculator problem. Take out all the batteries, hold the DEL button and put the batteries back in (keep holding the DEL button until all batteries are put back in). This will restart the calculator and restore it to its default settings...but it makes it work again!

"Reflashing the OS is probably the thing to do now. I think there's some trick that throws the calc into OS receiving mode. Hold down DEL while putting the batteries in? I don't remember if that's it. Go to 1-800-TI-CARES/ti-cares@ti.com if you need specifics on getting the calc to take an OS upload given the state it's in."
