Mon, 24 May 2021 20:13:07 -0700

I took apart my TI-83 plus to see what was wrong with it, and I found out that the c7 capacitor does not work properly. Does anyone know what the c7 capacitor is so I can replace it?

Texas Instruments TI-83 Plus: Calculator no longer working after opening it up

Fri, 27 Nov 2020 12:42:20 -0700

Hello I tried to clean the keyboards of my calculator by taking apart according to YouTube but when I put it back together the screen just goes in and out sometimes and shows a lot of lines but nothing clear. I remember I had to pull back the thin metal or aluminum sheet to get to the keys but I put it back. Should there be anything specific to look at when I open it to see why it’s doing that?

Texas Instruments TI-83 Plus: My screen is dimming when lots of pixels are dark, how do I fix it?

Wed, 04 Dec 2019 11:15:12 -0700

The screen on my TI-83 keeps becoming dim when I rapidly type numbers, or go into certain things like the finance app. I think it's because there are too many pixels that are black that it seems to refuse to show up. Is there a way to fix it without opening it up, or do I have to order a replacement screen?

Texas Instruments TI-83 Plus: What is this missing component on the logic board?

Sat, 06 Apr 2019 20:02:59 -0700

Opened up my TI-83 Plus calculator (its an older model: 8TA837MB-30B). The board says TI-83 (F) on it. When I opened it, an inductor in the L6 slot was missing. This is located near the I/O jack to connect to the computer. A commercial picture of the board is shown below with where the L6 inductor is supposed to be. I just can’t find out what value of that inductor is so I can replace it. Any help would be much appreciated. I’m doing this more for soldering practice rather than just buy a new board and replace it. Thanks!

Texas Instruments TI-83 Plus: Why is does my screen get jumbled with random characters?

Wed, 23 Nov 2016 02:27:11 -0700

I just got this TI-83 Plus yesterday. I haven't even got to really use it. Today, I sit down to graph a problem and the screen starts glitching and there is lines in random places and numbers everywhere. It is a jumbled mess and I have no idea how to fix this. I tried to shut it off and turn it back on and everything is normal for a bit, but then it starts acting up again. I also replaced the batteries and it's still not working. How do I fix this?

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.

Texas Instruments TI-83 Plus: TI-83 plus won't turn on

Tue, 23 May 2017 13:09:01 -0700

My TI-83 Plus has sat mostly unused for the last 8 years. Today, I plugged in 4 batteries, and got an all-black screen. Assuming it was a contrast issue, I hit 2nd+down repeatedly. That did nothing. I then took out the batteries and put them back in. This time, the calculator wouldn't turn on.

I searched for the issue and tried the standard methods of holding down "CLEAR" + "ON" and also holding down "DEL" while taking out a single battery and re-inserting it. In neither case did the calculator turn back on.

When I take out all the batteries for about 20 minutes or longer and then plug them back in, then the calculator does turn back on, but does the same "all black" screen a couple of times before reverting back to simply not turning on at all.
