Whenever I turn on my TI-83 there are some parts in the screen that wont turn on. For example, if I put in 4+4, the answer comes out in the right side as 4. But there is a vertical line that blanks out that line. So the middle of the 4 is missing and there is a horizontal line so I can't even tell what that number is. Can someone help me?
What are the parts of the calc screen?

I've had the same problem with both my old TI-85 and TI-89. Could someone please help with this? Is there a way to fix it?
Several vertical lines of pixels never turn on for me. Sometimes, when I keep the screen on for an extended period of time, some of the lines come back, but this is not an adequate solution.
