Display defect -vertical stripes

[marcos]

My T400s display started developing vertical stripes of white, black or random color, each stripe is about 1.5" wide.
If I press at the base of the display, the stripe changes color an most of the time goes away.

Does anybody know what is the faulty component, Since I had success asking for free replacement parts using the online web service, I want to try that before shipping my machines out.

It sounds like faulty column drivers in the panel. They will not ship the panel to you

richk is correct.

LCD panels are not considered CRUs, and thus will not be shipped to end-users. You'll have to get depot service (or an on-site replacement if you have a warranty that allows for that.)
