So one day, I was turning on my calculator after a while, and it will not load. The progress bar gets to the half-way point, then stops and says that the os is not found. I have not done any messing with the code.

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

Mon, 04 Dec 2023 17:49:13 -0700

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?

Hi! I have a TI-Nspire CX calculator, and now my calculator can’t turn on the screen. It’s broken maybe is because I am trying to upgrade the calculator to a TI-Nspire CX CAS calculator.

I have connected it to a working calculator and attempted to turn it on that way. I know there is a way to push a sequence of buttons to reset it, but I cannot find what they are. Does anyone know how to do this?

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.

TI-84 Plus CE: lcd screen is cracked---can it be replaced?

Sun, 07 Mar 2021 16:35:55 -0700

i accidentally dropped my TI84+CE and a portion of the LCD screen is dark when I turn it on. Overall, the calculator still functions fine, but that sliver of the screen doesn’t display anything. It appears that the LCD screen is cracked. Can one purchase and replace just the LCD screen?

TI-84 Plus CE: My screen has liquid in it.

Tue, 10 Nov 2020 09:36:38 -0700

So I have a TI-84 Plus CE that was sitting on my desk, and a closed container of isopropyl alcohol fell onto it. I didn’t think anything of it. Now, I noticed (it’s been a couple of days) that my TI had white residue all over the bezel. And to my horror upon turning it on, the entire polarizer is soaked and the screen is extremely dim. What do I do?

Texas Instruments TI-83 Plus: Is it possible to increase archive capacity

Fri, 06 Mar 2020 10:24:57 -0700

If I were to obtain a higher capacity version of the eeprom that is used for archive memory (same chip series, same manufacturer, higher capacity variant), and removed the original eeprom chip and soldered the new one on instead, would the TI-83+ be capable of :

a. Using it as archive memory at all?

b. Utilizing the full capacity of the eeprom?

c. Even running the OS properly?
