Hey, I just bought a TI-84 plus for school a few weeks ago. it was working fine and all until today. I had it in my bag along with a little drink package and somehow it got ripped apart and the whole thing leaked in my bag. By the time I noticed it was all over my books and also some on the top of the calculator (where the USB port is). I wiped it clean and checked if it worked. It seemed to go on so I turned it back off. Then a few hours later I tried to put it on again but it didn't go on anymore. So are there any people who know whats going on, chip dead or something or is there a solution? I don't really want to spend another €100.
