I have a vertical red line on my display. It does not appear on the external monitor. Sometimes it is two pixels wide, sometimes one. When I press on it with some force (not just a light touch) it sometimes changes thickness or disappears, but returns with either one or two pixel thickness when I release pressure.
I hae a Lenovo x201 Tablet (0831CTO) Multi-Touch display wih a 6QET68WW (1.38) BIOS.

The problem is something called a column driver. There is a connection to every column of pixels on your screen. If you have a wxga screen, there are 1280 of them. The connection is made by a strip of tape with contacts, that is held against the back of the panel by the adhesive between the contacts. Sometimes, the tape works its way loose due to age or vibration. It can be strained through incorrect routing of cables, etc during assembly or repair. It can also come loose if the screen is hit or strained. The "fix" is to replace the screen. If it is under warranty, I suggest calling Lenovo.

Aack. Now there are several lines.
My laptop's warantee just expired a few months ago.
I must say, I've owned several IBM laptops over the past fifteen years and I've never had a workmanship problem like this.
Can I open the thing up and reattach the connection? Can I have it repaired rather than replaced?

"The "fix" is to replace the screen."
I have this problem, my laptop is not within warranty, a new screen is expensive, for now, a folded piece of paper inserted behind the plastic fascia pressing on the place that has come unstuck is solving the problem, it moves sometimes and needs putting back in the right place again, but it works well enough.
