| hey everyone....i was hoping to get some help with my ti-89 (obviously). I just pulled it out of my attic and it turns on just fine but three of the buttons don't work...."2nd" "=" and "(divide symbol)" any ideas what could cause this? i took it apart to see if there were any components and there isn't a one. thanks all! |
