SOURCE: TI-83 Plus silver edition won't turn on.

the screen may be at the lowest dim setting, try turning it on, then pressing the 2nd key and then hold the up key and see if anything appears, if not let me know and I will try to figure out something else, I own a 83, 84, and 89 so it shouldn't be too hard to figure out

That means that you know your calc crashed. This can be caused by taking out the batteries durring running time, happened just randomly. Well nothing to fear just press clear and it should go away but if it stays on that screen you have problems and is best to try some of these methods. Take out all the bateries and press and hold the on button for 30 seconds. Put the batteries back in and it should have reset. Warning you should archive everything incase this happens. To archive go to 2nd mem and hit enter to put a astrick next to the app (meaning archived)

SOURCE: TI-83 Plus Problem

We have a TI-83 plus for about 3 yrs. It has been working very well until we had to use it again after summer break. Now when, you turn it on, only a black line appears on top and slowly disappears after about 2 sec. I've tried 3 of the recommendations on, taking the batteries out, pushing the clear while replacing the batteries, and the 2nd button with pushing the arrow keys and last holding the DEL button while removing a battery. None of these suggestions work, what else can I do?

How can I fix HP12c when keys do not respond?

HP lists on their site (and in user manual) a way to run a key test to see which keys are bad. I'd start there.Type "hp 12c key test" into your search window on your browser and the first thing that comes up should answer it. Took me about 4 seconds to find this.

My TI-84 calculator isn't working. When I press the "ON" button, sometimes it would respond, but most of the time it doesn't. The screen just remains blank. I've changed my batteries...

try taking out the triple A batteries and leaving the calculator to sit with them out for a minute or so, replace them and check if it's fixed. If that doesn't work you can do the same, but take out the small button back up battery as well. If you're still not having luck you should call ti cares (800-842-2737) they're usually helpful.

How to fix a none responsive button in hp 35s calculator

Resetting the Calculator
If the calculator doesn't respond to keystrokes or if it is otherwise behaving unusually, attempt to reset it. Resetting the calculator halts the current calculation and cancels program entry, digit entry, a running program, a SOLVE calculation, an ∫ FN calculation, a VIEW display, or an INPUT display. Stored data usually remain intact.

To reset the calculator, hold down the C key and press GTO . If you are unable to reset the calculator, try installing fresh batteries. If the calculator cannot be reset, or if it still fails to operate properly, you should attempt to clear memory using the special procedure described in the next section. If the calculator still does not respond to keystrokes, use a thin, pointed object to press the RESET hole.
The calculator can reset itself if it is dropped or if power is interrupted.


If the calculator fails to respond to keystrokes, and you are unable to restore operation by resetting it or changing the batteries, try the following MEMORY CLEAR procedure. These keystrokes clear all of memory, reset the calculator, and restore all format and modes to their original, default settings (shown below):
  1. Press and hold down the C key.
  2. Press and hold down the R/S key
  3. Press i (You will be holding three keys simultaneously)
  4. When you release all three keys, the display shows MEMORY CLEAR if the operation is successful.

I fixed my calculator, but i am not sure how I did it. I just took it apart, put the circuit board to a fan, wiped it, and put it back together. Then when I turned it on I pressed "2nd" first then it started working.

sounds like your backup battery is dead.. and maybe the clear or del key stuck down as either way it could wipe the program.. The solution i think is to hit the TI website and get the software reload and directions to reload it from there.

Turns on but does not respond to buttons

Try replacing both the AAA batteries and the back-up batteries. This should probably fix the problem. If not, contact the guys over at Texas Instruments for replacement parts if you need them.
