The stuck line is probably a 'slightly' failed edge connection between 
the LCD itself and its integral 'driver' circuit board. The connection is 
made with a heatset adhesive, and while in theory it's possible to 
securely re-attach the connection using a heated tool (think something 
like precise temp controlled clothes iron), I've never done it and so 
can't really give any practical suggestions as to how it might be done.

I think for most people, replacing the entire LCD panel is the only 
practical repair.
