Hi guys,
I'm an Italian boy and I'm trying to repair my ti-89 calculator.
Probably due to a battery corrosion, I have find some problem with numeric button (- 3 6 9, and t) and a connection problem to pc.
I'm been able to repair the button (create wire connection on a burned connection) but in order to fix the communication I need to replace the burned ceramic condenser C43. Do you know its value? I already tried to change but doesn't work. I'm sure that it is an hardware problem because I have no problem to communicate with my friend's ti-89. Unfortunately he don't give me a chance to investigate on his calculator.
Thanks
