WON'T TURN OFF

I've tried numerous times to turn the calculator off, and it does so for a split second, but then it turns right back on. It seems the only way to turn it off is to take out the batteries? It used to work fine until a couple weeks ago. Any ideas?

    AHHHHHH!!!! JUST TURN OFF!!! 
    I know someone has a solution for this, it has something to do with changing settings, but I can't find it again....
    Does anybody know? I'm not doing an update, I don't have a cable.

Under your On button might be some dirt, that keeps triggering the On button, and thus, keeps it on.

Hello , I seem to have a problem with my casio fx~9750GII module calculator. When I turn on my calculator , it stays frozen on the MAIN MENU set i.e consisting of RUN-MAT,STAT,GRAPH,DYNA,TABLE,RECUR,CONICS...


Checking the batteries is the first thing one should try. It is possible that for some reason the screen may be too dim.
Reset the calculator by pressing the button on the back. The screen should show the menus. To adjust the contrast you must press the E key (no need to press the ALPHA key for that.) then press F1 to access the contrast setting feature. Press the Right pointing arrow to increase the contrast.

Calculator will not print


I don't think you'll find parts for this, however I did find a used one, buy it now, for less than $20, shipped: http://cgi.ebay.com/Texas-Instruments-Electronic-Printng-Calculator-TI-5045_W0QQitemZ160148715050QQcmdZViewItem Buying a used unit and either replacing yours or using it for parts is probably your best bet.

I've had my ti-86 for a very long time & recently it just quit working. I changed the AAA batteries & the back up battery & it will not come back on. Please help???!!!!


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. Does it?

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.

T30 always comes up with record-ready display screen


T30 defaults to an opening display screen based on where you were when you last used the device. When leaving from the record folder and record mode, you will always open with the record-ready screen. If you left your T30 while in the music folder playing a music file, you will be returned to that.

This record-ready display screen has a numeric and bar time line. The numeric values of the line are in hrs:min:seconds. This line is also split: the right half of the line indicates the total amount of available recording time, while the left half indicates your time as you record. If you compare the values of the right and left sides of the numeric bar while you are recording, you will see that the right side is diminishing as the left side increases in numeric value. When you complete your recording and save your track, the right side will now indicate the new total time (the amount your screen first displayed LESS the time value of the track just recorded).

When you are playing a music file, if you watch the time display, you will see the numeric information changing in the same way. The left side indicates how may hrs:min:seconds your track has played while the right side indicates the total time value for that file and will be correspondingly decreasing while you play your music file.

So in the short, you don't need to worry much about your display screen unless you open in the wrong folder or you need more recording time than is available. Then it has a message for you.

For the remote to work, make sure "video" is selected (instead of "tv"). It's the little button on the remote under the red button at the top that turns on the TV ("TV/Video")
As for the split screen, I've had that happen numerous times (when I lose power or revert to default settings). YOu have to go to Setup, Display, and select 4:3.
I hope I have helped you. I'm having other problems - with the audio. Some channels have no audio (maybe 3 or 4) and 2 channels are in SPANISH!!! (??) Weird that it's not uniform. I even tried reverting to default settings (and got that split screen!), but didn't help. It "jumped" a few times to the input type screen. I'm thinking some chip got fried or something. I've had it almost 2 years, and guess that's the "built-in" obsolescence!! :-)
Good luck!
