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.

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.

Wrong calculator link. OP said 84 Plus CE. You gave link to old 84.
I know he said CE. The basic, Silver, and CE are assembled in a similar fashion. The major difference is the software ad mainboard.
