Troubleshooting the TI-83/84 Graphing Calculator

Choosing Quit or Goto, the Minus key vs. the Change Sign key, Using parentheses, Problems with the Window Range, Xres, Problems with Tables: Missing y-values, Can't delete x-values from the table.


TI-83/84 Troubleshooting (Stan Brown, Oak Road Systems)

Error Messages: Syntax, Window Range, Dim Mismatch, Invalid Dim.  List Troubles: I've lost a list from the STAT EDIT screen, I can't clear the numbers from a list, I left out a number from my list.  Graphing Troubles: My screen is blank, except maybe for the axes and the grid, My screen is covered with horizontal or vertical lines, My screen is completely dark, every pixel filled in, There are no tick marks on my graph, An extra line or curve appears on my graph, I can't graph more than one equation at a time, My normal distribution from SHADENORM looks wrong. 

Other Troubles: My screen is too light or too dark, Where's the correlation coefficient?
