The lcd is connected to a PCB with a driver, you can unsolder the LCD pins from the driver board. I think you are able to unsolder the entire board+LCD from the main calculator board, but I haven't tried that.

Your best bet at finding a new LCD would be to buy broken calculators off of ebay.

I have a tinspire (ti-84 plus keypad) calculator that has a messed up lcd screen. my best guess is that it needs to be replaced. is there a way to replace the screen?

If you see all kind of symbols on the screen insted of numbers and letters try to reset the Ram or maybe one of the application causing this
if it will not help it could be that the RAM CHIP on the mainbaord is faulty and need to be replaced
let me know if you want to fix the TI84 Plus

My daughter broke the screen of her TI 84 Plus Silver Edition

Even if it were available from TI, the LCD screen is not generally repairable and is either an integrated part of the mainboard (hardwired) or is attached to the mainboard by a ribbon cable. Either way, desoldering and then resoldering is tough even if you own the equipment to do this kind of work. Next option: check eBay for another used calculator.

Broken screen on TI 84 Plus SE, TI83 plus and on ti73's I have about 25 graphing calculators. Students have simply scratched the clear plastic screen on 3 of the TI-73's. But the others have had the under...

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.
