Question about Texas Instruments TI-83 Plus Calculator

3 Answers

TI 83 I had a bad accident, broke my back and could not use my TI 83 for over a year. When I tried to use it, it did not work. Replaced all the batteries, still did not work. Called TI but they said hard luck out of warranty. As it was very expensive and I need it for exams, what could be wrong with it? Is it repairable? I have calculators (non-graphical) much older than this that still work well. I am in the UK. Terry email: kotchki@tiscali.co.uk

Try Adjusting contrast:
Hold down "[2nd]" key press up or down arrow repeatedly to lighten or darken contrast.

First attempt reseting:
Step 1: Remove all the batteries
Step 2: Hold "Clear" key down
Step 3: Still holding "Clear" key reinstall batteries
Step 4: Still holding "Clear" key press "On" key until home screen is displayed.

Second shot reseting:
remove all batteries including lithium ion (backup battery), wait 3 hours and reinstall batteries.

Third Shot reseting:
Step 1: Remove a battery
Step 2: Hold down "DEL" key reinstall battery
Step 3: Possible msg pops up saying "Waiting ... Please install software" IGNORE msg and take out battery again
Step 4: Reinstall battery do not hold down "DEL" key

reseting will cause the handheld to loose all of its stored memory.

Other than that you will probably need to buy a new calculator

Hope that helps!

New batteries and won't turn on


You might want to check the batteries, and make sure that they're in the correct way. If they are, then you either purchased bad batteries, or your 83 suffered a catastrophic failure/broke

TI 83 plus calculator has dim screen.


TI calculators have an annoying habit of dimming the screen when the batteries are changed. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

TI-83 screen is black


The "color" on your screen reset to dark. You can adjust it by pressing "2nd" and the "up" arrow (or "2nd" and "down" arrow) repeatedly.

TI 83 Plus won't turn on after battery change


I was having the same problem...I found the info below on another blog and it helped me fix my calculator problem. Take out all the batteries, hold the DEL button and put the batteries back in (keep holding the DEL button until all batteries are put back in). This will restart the calculator and restore it to its default settings...but it makes it work again!

"Reflashing the OS is probably the thing to do now. I think there's some trick that throws the calc into OS receiving mode. Hold down DEL while putting the batteries in? I don't remember if that's it. Go to 1-800-TI-CARES/ti-cares@ti.com if you need specifics on getting the calc to take an OS upload given the state it's in."

Most likely your battery is dying.

You can replace by removing 6 screws at back of calculator, but cost of battery is around 40% of buying new TI-30XA from Amazon, Staples or elsewhere.

I've used TI-30XA's for years, batteries usually last 2-3 years, then I buy new calculator. The one time I tried to replace battery, fading display still problem, so circuit board had gone bad.

So you could try battery replace and may be OK, but also may be waste of time and $$

My ti-83 plus has OS problem


That happened to me a few years ago - my friend tried to give me his operating system, and my calculator was all locked up like that for a while. There's some kind of reset code - pressing some buttons while putting a battery in - but it's been a while, so I don't remember which buttons.
