My 9th grade Math teacher just gave me a TI-82 Calculator, when we opened the battery cover, the batteries were beyond corroded, we took them out, and took some donor batteries, put them in, and pressed the on button. And I get lines throughout the screen, so I took it apart, and couldn't find anything wrong with it. I don't know what is wrong.
