TI-84 Plus: My calculator has a burned hole in it. How can I fix?

Tue, 01 Oct 2019 11:08:14 -0700

It got stabbed by a compass (the math measuring one in my bag) but the strangest thing is that it seems to have burned a larger hole around it. Is there a way to replace some parts in it or get someone else to fx it?

Texas Instruments TI-30 XS Multiview: Calculator turns off while typing and won't turn on unless I reset

Thu, 09 Apr 2026 14:34:27 -0700

The device turns off while typing and won't turn on unless I reset, clearing out the work. It still calculates after I try a few times but I lose a lot of time typing it in over and over again.

Texas Instruments TI-Nspire CX: Why isn’t my ti-nspire turning on

Sun, 06 Apr 2025 04:35:01 -0700

My nspire had low battery and when I went to charge it it wouldn’t charge and so it shutdown but when I got a spare battery the device still won’t turn on or at the very least the display doesn’t work. I tried both the spare and the original battery on a different device and both worked for that device

TI-84 Plus Silver Edition: Only 1 graph for 2 Inputs?

Thu, 05 Dec 2024 14:39:20 -0700

So I have two inputs put into my (Y=) values and both of the equal signs are "highlighted". Then when I go into the graph, only one equation shows up. Yes they are 2 different equations, one is a cubic and the other is a quadratic so they should look totally different. If I go to the table menu after viewing the graph, only 1 set of values appears and if I go back to the (Y=) menu, the Y2 equal sign isn't "highlighted" anymore either. Bottom line is that no matter what, only one equation shows up on the graph.

TI-84 Plus CE: What is an acceptable battery voltage?

Tue, 12 Nov 2024 15:27:16 -0700

I know the TI-84 Plus CE has a 3.7V battery. It wasn't turning on so I checked the voltage using a multimeter and got 3.4V. I thought this was enough to power the calculator but after a good night on the charger it worked. This confuses me, so I was hoping someone smarter than me could explain this? Is there a general rule of thumb/threshhold for hpw low a bettery can be before it needs replaced/charged? Thanks!

TI-84 Plus CE: Is there any way to change or repair the ribbon cable?

My screen has white vertical lines and is lacking of colour intensity everywhere. I already did the self diagnostic test, restarted it, reinstalled the os. I really think there is a problem with the flex cable. On ti 83 calculators it was possible to solder cables to replace the ribbon cable, is it possible on ti 84 plus ce?

TI-89 Titanium: missing horizontal pixels on display screen

Thu, 01 Jul 2021 09:17:56 -0700

I have two missing horizontal lines of pixels. The first is just below the tool bar and the second is almost half way down the screen. I ran the self test for the calculator and confirmed that the lines were missing. Is this a hardware problem or software problem. How can I determine which it is. If it is a software problem will a reset fix it without removing the factory installed programs. But if it is a hardware problem would this be an easy fix.

TI-84 Plus CE: Why does my TI-84 Plus CE graphing calculator die fast?

Fri, 23 Apr 2021 13:20:25 -0700

When charging, the battery indicator on the screen stays the same at about 3/4 of the rectangle. I left it for about 5 hours and it still isn’t fully charged. When I unplug it to use it for 5 minutes, the calculator battery instantly drops to about 1/4 of the rectangle.
