TI-83 Plus Calculator Dead. Repair.

[@monieshacampbell4699]

Sir you are a freaking saint!! I just fixed my calculator 30 mins before my class ! Thank you!

[@kirstyeisenhart55]

I opened up a TI 83 and found one of the copper strips was almost gone due to a battery leak. I took a piece of copper tape and folded the adhesive over itself leaving just a bit of adhesive to tape to the calculator. Worked perfectly. Thanks for this great video!

[@dylandavenport]

You’re a wizard! Fixed my calculator. Cornell University Grad student here. Just saved my life. God Bless

[@vikcheban923]

You don't need to take the whole back off to adjust the metal wires touching the copper. You can see them and adjust them using a tiny screwdriver (or any small enough object to get through the two little rectangular holes below the batteries). I did and my calculator (which wouldn't even turn on before) works fine now. Thank you for the video, otherwise I wouldn't have known what to look for!

[@annmariegrant4037]

@vikcheban923 Thanks for this tip! My T6 bit can't reach the bottom row of screws so I can't remove the back cover. I was able to use a hair pin to shift the connectors as you did (hair pins are a multi-use tool, I swear). And BAM, ole faithful is back in business!

[@thomaslautenberger6447]

Thank you. I was frustrated trying to fix my calculator. This fix was able to resurrect my 10 year old TI-83 plus.

[@smfl106]

Thanks You helped me as well. My calculator is now 25 years old and still working fine. They don't make em like they used to.

[@one_n_a_billion]

Can't thank you enough for this video, saved my 20-yr old TI-83 that I thought was trashed!

[@tombarbaro345]

Wow - thank you so much for taking the time to walk us through this fix. Couldn't figure out why the replacing the batteries work...

[@nadiachekiri4317]

You are awesome! Mine was so badly damaged I had to solder it but I never would have known to do it or have the confidence to do it without your video. Thanks so much!

[@micrometer1484]

I tried several other fixes like removing batteries and such but none of them worked. Your solution worked! Thanks

[@ElAnvaBar]

Thank you sir! I´ve been able to fix my old TI-83 which i hadn't touched in years, with your first suggestion!

[@goku445]

haha, that must have been a good feeling. :)

[@dlawjdtjr9349]

I was in little panic as i thought my calculator is dead. I bought this in 2008 and used only for a one year and never took it out until 2022 today. But the problem was exactly same as this video. I didn't have that "T6 TORX screwdriver" so i put the toothpick in too the liitle hole where the battery cover was placed to bend that metal wire to touch the contact you mentioned and Wow it's working again!!! Right side of metal contact was barely left haha. Thank you so much for this video

[@izzyp8784]

Thanks for posting this vid. I opened my TI-83 ( not plus) calculator and the contact point was corroded. I moved the connector and got my TI-83 working again after having it in my garage.

[@c.davidgraves4848]

Thank you for the information. I did not mention the TI-83 (not plus) because I have never owned one and I did not know how they are built.

[@IHCgraphix]

Omg! I just stumbled across your video and just fixed my TI-83 calculator in less 2-3 minutes. I just used some tweezers I had laying around to slightly bend the connectors without actually removing the back cover. Thanks a bunch.

[@nickzuzulo3754]

Thank you so much. My wife has 2 of these. I was in a hurry so on one of them i just stuck an eyeglass screwdriver in the holes by the contacts and bent them down. Awesome 👍

[@Johnslist]

brilliant! I particularly like the ability to fix by just adjusting, instead of saying, 'now go find a replacement board.'...

[@soluchiomolu2875]

thank you so much, my mother and i used a pin to bend the metal part without taking off the back, by putting it through the hole. it works!!!

[@stuffedcrestpizza3449]

let me just pull a mulit meeter out of my ass real quick and while im in there let me pull out gta6

[@applepine1048]

THANK YOU SIR I OWE YOU ONE I MOVED THE metal contact, where the copper is nearly removed JUST A LITTLE BIT WITHOUT OPENING THE CASE i used one of these voltage checker contacts pins. AND IT WORKS NOW, TRILLION THANK YOU!!!

[@zayjay6082]

Tried this today and it worked!! Did it myself too. Thanks so much!

[@GhostHuntersOfOzarks]

You are the bomb, Thanks your video helped, not sure how just watched it popped out the memory battery, stuck a blow gun dart with super glue on its tip in the bat door tabs, and moved the little metal wire from the batter terminal. Put battery's back in. Powered right up. You the man. Thanks

[@tonychontong1052]

Oh my God, I tried everything else and nothing worked until I did this. Thanks very much!!

[@ScBoyyx]

Excellent video. I followed your steps and was able to get my calculator working again! Thank you.

[@JCG0001]

Really useful step by step diagnostic approach, I had worn contacts and also the wrong memory battery cr1632. Would recommend people remember to ground themselves or touch the side of a grounded computer case to discharge any static electricity before touching the chips otherwise they could fry and never know that's what caused it.

[@eda3515]

Worked, thank you! Mine used to fade when I did complex tasks

[@schwda01]

Thank you so much for posting this video. My son and I just followed your approach and it worked!

[@neomartinez9920]

Thank you very much. I fixed mine in less than 15 minutes. Had the right tools followed your instructions and good to go.

[@myyu5211]

Thank you very so much for sharing your knowledge and experience. I will try to fix my friend's tomorrow. Cheers!

[@geoffhunt1]

Wonderful Video. Fixed in 5 minutes!

[@samuelkobe]

You’re a legend! Just helped me sell my old calculator!

[@javiermartinez-ge8ss]

Thank you so much sir I fix mine by watching your video I appreciate you for taking your time to show us 🙏👍

[@ElliBuzz]

Thank you so much for this very helpful instruction which brought my TI-83 Plus back to life. Although I hadn't such a specific screwdriver and therefore couldn't open it form the back, bending the pins through the holes worked as well!

[@boricua3492]

Worked like a charm ! Thank you !

[@nathanhancock3205]

Thank you for the very helpful and informative video, sir!

[@zanigreg]

Thanks so much for your excellent tutorial on repairing the TI-83. Mine had the exact problem. Your test suggestion with a meter indicated no power from the batteries showed no current. Did your fix opening up the device and moving the contacts. It solved the problem completely. My 16 year old TI-83 now works again. Thank you so much.

[@WesamHezam]

What if I don’t have the weird machine thing

[@ngocbui3761]

This worked for me. Thank you kind sir.

[@oOMeowthOo]

Ha ! It's really those two pesky brass like metal plates acting up, after all these years of my TI-83 hibernating, the contact area became rusty and isn't conducting currents anymore, moving the contact point around, revived my calculator

[@hellene.5125]

Thanks! I used your first suggestion and it worked!

[@mohammedredwan8451]

wow this was awesome. Saved me another 60-80$ on a new one

[@MikeLongo]

Thanks for taking the time to make this very informative video! Did you ever make one regarding the connection between the system board and the LCD display? Looks like that is my problem. Thanks again!

[@c.davidgraves4848]

If your TI-83+ has an erratic or "glitchy" screen, I do have a video on that topic: kzbin.info/www/bejne/Y4nKg2iHp6x7eJY

[@naderhumood]

Terrific keep it up, Thanks v much Sir.

[@lorenzomendoza2109]

Worked perfectly. Thanks!

[@kathylaughter2012]

Omg THIS ACTUALLY WORKED! But I didn’t have to take the back off. I am aged to clean up the copper pads with some alcohol and boom worked!

[@b0ssPlz]

Very usefull! Thank you so much!

Where is the screwdriver from?

[@FadingBulb57227]

you can also remove the torx screw with a very small flathead screwdriver

[@tjgomez4883]

Thank you

[@PaulJCost1]

Happened the same on mine too. Fixed it

[@battlehrfred]

Hi it seems like you got a lots of know ledge and know your calculators. nice video and lots of info and examples. My ti83plus wasn,t used for about 1 year, i took it out of the drawer to use it,wouldnt turn on,so i replaced all of the 4 batteries except the 1616,it test 2.70 volts,seems ok, so after new installing 4aaa,it still did not want to turn on,finally after holding the on button down,then replacing the aaa battery with the on button held down, it came on, but a complete black screen is on my screen.. and i cannot get the black screen to go away... btw there is 6 volts on these contacts that you showed in this video. ty 100--100

[@c.davidgraves4848]

A dark screen can be caused by the contrast being turned up too high. Check out this video. kzbin.info/www/bejne/f2OpY3x_jdhpjcU A bad internal ribbon cable can cause all kinds of problems, including a black screen. See my video on cable repair. kzbin.info/www/bejne/Y4nKg2iHp6x7eJY

[@anthonyc7900]

Is there any hope if my battery connectors are almost all green?!

[@c.davidgraves4848]

Try polishing the contacts with very fine sand paper. You might be surprised at how much orange copper metal is still there.

[@anthonyc7900]

@@c.davidgraves4848 thanks for the tip. I tried cleaning it with alcohol and q-tips to no avail.

Can't do it You have to take off the cover, no two ways about it

On my calculator dont work the buttons 1,2,3,+,"STO" ,the ENTER button and the left key

[@mickysummerville5314]

Mine seems to be draining the battery very quickly. Do you have any ideas or possible fixes for that issue?

[@saulsantana7167]

My doesn’t seem to work still it had very little wear and I bent the prints and it still doesn’t turn on any other suggestions ?

[@Teofilo750]

Hi I have a Ti - 82 calculator that I bought on ebay, unfortunately after a while I was doing operations it crashed in particular while doing operations with a variable, after it got stuck, I tried to use the batteries to reset it but it did not given no result, I also changed the buffer battery, but nothing now turns on but nonsense digits appear on the display and it does not turn off! Batteries must be removed. Can anything be done to solve the problem? Thanks.

[@CrimsonDevil_Rias]

Instead of moving the metal contacts to a good place on the copper sheets, I tried treating the copper sheets with isopropyl alcohol It worked.

[@amirtorhan2762]

Anyone having issues with any TI calculator, try to change the contrast by pressing 2nd and the up/down arrows. Often this can be the issue and not the batteries.

[@NganTran-se2ip]

Nope, not for me

[@rockybravo3554]

I had a glitchy screen problem and it resolved to the being dead problem should i be worried then?

[@slun80]

Worked for me! Thanks!

[@georgeevangel899]

Where can I get a coin battey for a TI 83 They are difernt from TI 84

[@stickshiftstarship]

A watch shop should be able to help you out.

[@mr.magicman8001]

Ive got a ti93 with O/L on the positive and negative leads. All contacts on the display cable come back fine. Noticed a problem when it didn’t power on so I then changed batteries and then it gave me about 7 vertical lines and no life since then.

[@mr.magicman8001]

Update, now 450 ohms resistance on the +/- leads

[@XwaD666]

Mine only has two screws on the bottom and it won't pry apart after removing them, any ideas?

[@c.davidgraves4848]

I have no idea. Every TI 83+ I have encountered was held together with 6 torx screws and 1 Philips head screw. How old is your calculator? Perhaps there has been a design change.

[@JosephHuddleston]

My TI-83 is from 1996. Hopefully, I can fix it. It does not have the same scree holes. Only the two at the bottom.

[@Godangel1011]

My TI-83 Plus has been stuck on Exec Edit New. I have taken the batteries out, I have pressed on every key to make sure that none was stuck, turned it on and off, and basically everything I could have thought about and it still didn't work. It still says "Exec Edit New."

[@palemacaroon4836]

I found one of these walking home from school a few months ago, and it is only missing the carrying cover and half of the label around the screen has been cracked off, but otherwise it’s in good condition. The sad part though is that I cannot return it to the original owner because the name that was on the back has been scratched off.

[@warplanner8852]

Pretty talented calculator that it could walk home from school by itself! It's a keeper!

[@buckrogers5331]

Hi, can anyone tell me if this Ti-83 Plus can turn on if the button battery is not put in? I haven't used mine in a long while and it is dead. I've cleaned the contacts and still no dice. If it is the button battery then I'll go a new one (CR1616) is pretty hard to find here. Oh, it also has a bit of a 'burnt' screen. Many thanks in advance.

[@c.davidgraves4848]

The calculator will work without the memory battery. It just will not be able to save anything. BTW, it will also work with the CR1620 battery, which are more common than the CR 1616.

[@mickysummerville5314]

I have a battery drain issue. The calculator will drain the batteries quickly even if the device isn’t powered on. Anyone have a fix for that?
