@markcanham this is for informational purposes only. As my colleague @jayeff already mentioned, this fault should be covered under warranty.
What you have here is a loose connection on one of the data lines where the LCD driver boards connect to the LCD. Those are attached via a special process and can't be fixed by a DIY.er. The error itself is called a TAB error.
Sometimes you can verify this by applying some pressure on the bottom of where the line ends and see if that changes anything. Apply some pressure on the TAB that corresponds with where the line is on your screen. See if that changes anything. The attached image is just an example of what to look for.

This is just for information. Make use of any warranty claims you can. It's not an easy fix at all.
