The bottom row of numbers on my TI-84 (1, 2, and 3) have stopped working and do not input a number when pressed. Is there a way to fix this or someone I could send the calculator to in order to have it fixed?
Here are instructions on disassembly. http://www.instructables.com/id/Ti-84-Ba… You may be able to clean the 1-2-3 so that it works. If not, you can hunt around ebay or http://www.calculatorsource.com/ for a replacement keypad.
