Question about Texas Instruments TI-83 Plus Calculator

1 Answer

Ti83 plus calculator

My son has indicated as I observed; his ti83+ calculator loses its intensity on the lcd screen. As I touched the screen with data erratically entered; the screen would be very dim as if it were OFF and suddenly brighten with barely a touch and increase as the touch increased. My son previously indicated the calculator was glitching as if it was resetting. We have fresh batteries installed. John@msn

You didn't mention how old the calculator was so let me give you a little information to aid you in making a decision. First...solid state electronics don't last forever but a calculator should last a long time if it is not dropped, immersed in water, etc. I have a programmable model that is over 25 years old. Having said that, if the model is still in warranty, that would be the logical solution. If not then you have three opportunities.....the bad meaning pitch it out if you have received fair value from it (I don't know when you purchased it), the expensive (probably more than it would cost to replace) meaning calling around and asking a TV shop (not a computer shop) if they would not mind taking a look at it (some might) or if you happen to know an electronics tech...or (and this works) giving a call to the local junior college and checking to see if the instructor in a basics class might like to fix it (you pay for parts) as a class project, lastly (and this can work) a letter to TI customer service if the product is less than 5 years old saying, "I'm not sure what the mean time between failures is but my son's xyz which I have enclosed failed after approximately xxx hours use. As I am on a limited budget I was wondering if it could be fixed." You might get a response...most folks in Texas are pretty nice and TI is interested in maintaining their reputation. This will cost you a couple of dollars in freight. You, if you check around, can find very inexpensive (very sophisticated) calculators. I would also point out that there are many very sophisticated calculators free on the internet (not quite as handy as you have to use a mouse or the keypad (with some, not all) if you have a computer or the work your son does is also requires a computer. Hope this helps....Tango

Screen upside down

I have seen a lot of questions of this sort but I have never this this inversion in a calculator. You could try to reinstall the Operating system. For the TI83 Plus, the last OS version is 1.19. If it is a TI84Plus/TI83 Plus Silver Edition the OS version number is around version 2.55 MP.

Can you transfer ti83 os to ti 84?

The TI83Plus has the capability to transfer its OS to another handheld device. It is possible that the TI84Plus hardware will accept it. But why downgrade?. Why not resinstall the OS? The latest version 2.55MP is available on the TI website.
You say emphatically that you tried everything and maybe so, but I will ask you: Have tried to connect the calculator to a computer and explored its content with TI connect. You may retrieve some information about its status.
The TI connect software will allow you to transfer a version of the OS even if the calculator appears to refuse to turn ON (screen contrast problem.) If it cannot it will let you know.

Try again.

I suppose they can be replaced. You should contact the TI Consumer Support Department at They will be able to tell you where in your area of residence you can have the calculators serviced and how much It will cost you.

I have heard about a Casio program that gives credit towards the purchase of Casio calculators in exchange of TI calculators. Here is the link to the trade-in program.
I believe it is worth investigating this. You may end up replacing the calculators at a lower price. Casio calculators are very good and less expensive than the TI. You will be surprised to hear that Casio is the inventor of the LCD screen.
