Texas Instruments TI-30X IIS: Automatically adds a digit to the end of my entry

Wed, 22 Apr 2026 13:20:25 -0700

My calculator automatically adds a 9 to my last number every time I try to do math. For example, I type 5 + 6 and expect =11, but calculator does 5 + 69 and I get =74 :(

The 9 button does not appear to be sticky.

Texas Instruments TI-Nspire CX: TI-Nspire CX Cas Damaged Charger Port

Tue, 07 Sep 2021 08:37:33 -0700

This question is specifically for the CX CAS model of the TI-Nspire calculators.

The calculator is fully functioning except for the fact that it won't charge, unless the cord and charging port are aligned a certain way. It is not a problem with the cord, but with the charging port.

It seems that its contact points to the motherboard have been disconnected, as it has come loose and moves independently of the chassis, and only with luck can it be placed a certain way so that the calculator may charge. I would have to open it up and solder the contact points back to the motherboard, but I don't have the tools nor the know-how to do it.

I tried looking for ways to just charge the battery itself, since it can be easily removed with a Phillips screw driver, but haven't found the parts that would fit just yet. Any way to be able to charge it up would be appreciated.

TI-84 Plus Silver Edition: How do I fix the screen on my calculator?

Sat, 15 Oct 2016 14:56:32 -0700

A small table was placed heavily on the screen and now there is a small mark on the screen that is light in the middle and dark in the surroundings. When I type in a number, I can faintly see through this mark, but it gets a bit frustrating, and I begin Calculus next semester. I cannot afford a new calculator and this one is functioning very well. This screen problem is a nuisance!

Hello. I have a TI 84 Plus CE that has just been sitting in my backpack for the last couple of months (in hindsight wasn’t my best idea.) I took it out of my pack one day and found out the screen was cracked (pic below.) Is there any guide to fix it? The panel itself is not broken but the glass separating them is. Thanks!

TI-84 Plus CE: Why won't my Ti84 Plus CE turn on?

Mon, 04 May 2026 16:04:07 -0700

My calculator will not turn on despite being at full battery (when it charges it has a green light). The screen does not turn on when I press the on button, instead it stays black. I have even bought a replacement battery online, but this did not seem to help. Before, my calculator would often not turn from time to time, but still turned on occasionally, and it always turned on after a few seconds of charging it, but now it does not.

Texas Instruments TI-83 Plus: How can my calculator be fixed after water damage?

Mon, 05 Sep 2022 02:50:46 -0700

I have a Texas instrument 83 calculator that I bought in September, I have used it for only three month. Fortunaly around December, My water bottle got opened in my backpack and soaked my calculator. I try to dry the outside of my calculator and just let it dry inside for few days but after that I was not able to use it because it won’t turn on. I don’t if there is any damage water can cause inside the calculator. Is there anything that I can possibly do to have my calculator work again. Any place I can go. Please let me know ASAP. My email is ElroiKibret2015@gmail.com.

TI-84 Plus CE: How can I fix my flashing screen (TI-84+CE)

Mon, 04 May 2026 16:15:47 -0700

My calculator seems to have decided to no longer likes me, and is having startup issues.

It is stuck on a flickering white screen. I can’t turn it off. It doesn’t seem to be turning off on its own. I’d prefer to not have to completely wait for it to drain considering that I just finished charging it yesterday. The calculator does not seem to fully load at all and does not appear in the TI Connect CE program when plugged in to the computer. This is my personal calculator and I’d really like to have it fully working again, and if possible, salvage the programs I have on it. Is there anything I can do, short of buying a new calculator? Or is there a factory reset feature available anywhere I can use?

Does anyone know if there is a fix for this problem?
