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.

Thank you!!

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: One row of keys not working

Wed, 19 Jul 2017 10:49:50 -0700

The row of keys from "Clear" all the way to "Enter" (the most right row on the keyboard) of my Texas Instruments ti-83 plus aren't working. Also, the directional keys aren't working. Strangely, a few days ago, they still worked nice as normal. I already opened the calculator to find maybe any dirt or contaminated contact (cleaned them with rubbing alcohol), but still no functioning keys. Battery are fully charged, and the rest of the keys just work fine.

Does anybody know how to fix this problem?

Texas Instruments TI-83 Plus: Ti 83 Not turning on but has horizontal lines

Thu, 15 Sep 2016 19:29:18 -0700

Hello

My ti 83 will not turn on

The only way something will show up on the screen is when I take a battery out, hold clear and put the battery back in.

But when I put it back, horizontal lines show up on the screen

Also the longer I hold clear, the more lines. Also tried del button fix. And the color contrast is fine also. Any ideas?

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?

Someone tried to jam an ordinary headphone jack in there and ended up splitting the entire jack into pieces, i am unable to connect with the cable i just bought (and was hoping that it might still work but wasn’t expecting much). Where can i buy a new part for it? I can do the soldering myself but just need a new part.

Texas Instruments TI-83 Plus: Top screen cable appears slightly disconnected

Fri, 13 Sep 2024 10:22:52 -0700

My TI-83+ recently ran into the infamous glitchy screen issue, and I after checking the bottom screen cable using a multimeter to the best of my abilities, I am pretty sure that the top cable is the problem. Upon closer inspection, it looks like the top cable is slightly disconnected on one side, see images:

(The lines of melted cable are from my poor attempt at solving the issue using a cheap soldering iron, under the assumption that the problem was with the adhesive.)

Is it possible that my screen problems are due to this slight misalignment if the screen cable, and if so, how do I solve the issue?

Edit: After further thought, I think only the black part, which I assume to be the adhesive is misaligned. My question still stands though.

Thu, 08 Feb 2024 08:19:10 -0700

My screen is dark by default, I was trained to reset my calculator after each equation or session. When I do this, my screen's contrast turns faint and I have to adjust. Is there a way I can make it stay dark without having to reconfigure?
