Remove and replace the batteries should be first step. Also, I believe these have a smaller button-cell backup battery as well. Replace and reset to factory settings (backup any saved info if you can link with another TI calculator).

Hi I got a problem with Ti-86 which is a line of the screen pixel missing. I tried to increase and decrease the intensity of the screen (2nd and up, down). Also tried to go to MODE function. I have tried that for several times. It works great. The line of those missing screen pixel came back. I don't know why. Just try it.
