Texas Instruments TI-83 Plus: One of the button rows doesn’t work

Thu, 16 Oct 2025 07:42:33 -0700

The 2nd to bottom row of buttons, specifically Sto→, 1, 2, 3, and +, isn’t working. They were working fine until one day they stopped working. I use the calculator a lot so I would appreciate any answers because it’s $100 to buy a new one.

TI-84 Plus: The Entry/Solve button is not working?

Ok so I have a TI-84 Plus yellow-black calculator ( the ones that says school property) and I had it for a couple of years and now the entry/solve button doesn't work. All other buttons work but not that. Is there a way to fix it and dissemble a TI-84 Plus.

Texas Instruments TI-Nspire CX: stuck on loading screen upon plugged in

Wed, 30 Oct 2024 19:44:11 -0700

I have a TI-Nspire CX CAS that I recently tried to charge. It's been a few months since I last turned it on, and the battery was dead. When I plugged it in, it started loading but got stuck on the loading screen about a quarter way through. I have tried the following:

Updating the OS via the TI-Nspire Computer Link
Leaving it on charge for 36+ hours
Leaving the battery out for 12+ hours

All of these attempts have failed, and I don't know what to do next.

Texas Instruments Calculators: Why won't my buttons work for TI 84 Plus CE

Mon, 04 Mar 2024 20:53:53 -0700

There's an issue with two keys, the log key and the 7 number key, for some reason whenever I click it there is no response, I tried redownloading the os but it won't work, as per damage the entire case is fine, no scratches or dents and no water damage other than normal humidity, I am not sure if it is a stuck key I don't know what that is. I tried opening it up once but they heat up the plastic in there so it stays in place and you can't take it apart. Regardless this issue pursues no matter what I do, and I am unable to purchase another one due to financial stipulations. Any ideas

Texas Instruments TI-83 Plus: TI-83 Plus keeps going blank when it get's to the bottom of the screen

Sat, 04 Nov 2023 11:05:25 -0700

I have a TI-83 Plus Silver Edition that I just recently purchased because my other one was having this issue, and now this new one is having the same issue. What happens is I'll be typing stuff in and once the numbers get to the bottom of the screen, it just shuts off and I have to press 2nd on to fully shut it off before I can get the screen to show up again. I just gave it new batteries, including a new cell battery and I tried resetting it. Sometimes with this new calculator the screen will just randomly go blank before I've even reached the bottom of the screen.

Basically, either the screen shuts off or it turns really dark and a bunch of black lines appear when I reach the bottom of the screen. Does anyone know how to fix this? I bought it used, maybe somethings worn out idk.

Texas Instruments TI-83 Plus: How do I fix nothing working but contrast?

Sat, 21 May 2022 10:08:50 -0700

When the calculator turns on, the only function working is changing the contrast. You can put the contrast up and down, but you can't see anything being entered at any contrast. It seemed like it was the buttons, so I cleaned it, but it didn't seem to work.
