Ti-84 Basic Disassembly




How to disassemble your Ti-84 or Ti-84 silver.

Tools needed:
1) Torex #7 (t-7) screw driver
2) Small Phillips screw driver

Step 1: Remove Battery Cover

Remove main battery cover and take out batteries.

Step 2: Remove Backup Battery Cover

Remove the back up battery cover, this will require a Phillips screw driver. After cover has been remove *take out the back up battery.*

Taking out the backup battery will clear your system RAM, which means that all of your saved programs will be gone.

Step 3: Remove Rear Cover.

Use your Torx screw driver to remove the 6 screws noted below.

Step 4: Remove 4 Rear Screws.

After removing all 4 screws take a flathead screw driver or a knife and gently pry the 2 halves of the cover apart at each corner. You will hear it pop a few times, after prying a little cover should come off with ease.

Now that you have removed the rear cover you should see a foil backing over the main circuit board, to remove this you will have to first remove the 2 screws marked below.

Step 5: Remove Circuit Board.

Now you need to remove the other 4 circuit board screws.
After removing the last 4 screws the circuit board should be loose, lift up on it carefully to avoid flinging keys everywhere (sometimes the keypad will stick to the circuit board).

Step 6: Keypad

If your keypad didn't come out when you took the circuit board out it will look like this. Just take you keypad out and your Ti-84 is completely dissembled.

Step 7: Finished!

Now your ti-84 is completely dissembled. Do with it as you please, in my case my keys were sticky so I used some isopropyl alcohol to clean them off.

Thanks for the tutorial. Currently, I don't have the tools to get the screws on the back off, but until I get the tools, I would like to know if the faceplate comes off. Does the grey screen frame come apart from the black area with the keys? I want to get a colorful replacement part just for the piece that surrounds the keys, so, does it come off?

I needed a T6 Torx to disassemble. I had a TI 84 quit working. I ordered a used one on eBay, but the case had a name on the back and showed a lot of wear. I disassembled both to put the parts of one case into the other. Works fine.

Does anyone know if you can buy and replace the screen on a Ti-84 +. I work for a school district and we have 120 of them 5 years old. Some of the screens have the lcd's busted by kids. Any thoughts from anyone?

Thanks for the instructions! This helped me disassemble my TI-84 Plus Silver Edition and turn it into a Gold Edition! The outcome can be seen here.

 im thinking about disassembling my ti-84 so I can custom paint it a bit...will the calculator still function properly after disassembly? I disassembled my ipod mini once and it never worked again...lol

would it be possible to swap the front cover for a TI84 Plus one?  to allow for faceplate swaps.

Okay, so funny story. A week after I posted this Instructables a classmate came up to me and asked to see my calculator, he looked at it and said "I think we switched calculators during our last quiz" I looked at the one he had and sure enough there were all the programs I thought I had lost when I removed the backup battery on the one that I took apart. I took apart a classmates calculator thinking it was my own :) lol... I still laugh about it. Any way I had to share it...

Do you need an excuse? Like others have said my keys were sticky after spilling a mocha on it :) But I also wanted to take a look at the mainboard, I am thinking of trying to build an external display for it. -Mike

well, OK I admit that there is a lot of interesting stuff in there.
