Title: TI-83 (No Plus) Corrosion Help
Post by: _Nicco_ on November 08, 2012, 09:10:40 pm

Hi,

I have a TI-83 that boots up to a black screen and the contrast wont go down.  I open it up and I find some corrosion from what looks like a battery leak.  Any tips on cleaning that off and getting this calculator working again?

Here are some Pictures: http://db.tt/5RrHUHN7 (http://db.tt/5RrHUHN7)
