Hey guys, I was wondering if anyone has run into a problem like this.
I've got an fx-9860GII, but all the buttons on the same row as 7 or below don't work. All the other ones work fine, but without the bottom buttons I can't use the calculator. Even the on button doesn't work, so the only way I can get it to turn on is if I take the batteries out and put them back in.
I've taken it apart carefully, and found that there was a bit of leakage from a battery on the back of the keyboard board. I cleaned that off, and washed it down with isopropyl alcohol, but when I turned it on I had the exact same problem. Nothing had changed. I also tried doing a reset from the menu, as that's one of the few things I can do, but that didn't help either.
Does anyone have any ideas on what could be causing it? Thanks
EDIT: Just noticed it typed fx-9869GII in the title. That is meant to be fx-9860GII. (Sorry)
