There are blue, cyan, red, green or even white vertical lines occupying space in the left part of the screen. Namely those are mostly 1st, 3rd and 5th lines from the left and run from top to bottom of the screen. BUT THEY ARE NOT CONSTANTLY on the screen, that is the issue, they appear randomly and sometimes the screen is line-free. They are susceptible to moving the lid, and while opening, they are never present and while closing, they are always on. When I cease moving the lid, even moving the unit itself (without changing the screen opening angle) can cause them to reappear. When I bought the MBP the screen was ok, after 3 months one started to appear and now I've got three (its 6th month now) vertical 1-pixel wide bands running across the screen - fortunately in the leftmost part of the screen, but the issue is growing. Now apart from being open to stories of people having a similar problem, what I'd like to know is whether should I be able to fix is myself with proper tools, as clearly the issue seems to be mechanical, eg. the LVDS cable is loose or broken. I'd hate to part with the machine as its in constant use and needed to procure my work-related material on a daily basis. Any ideas?
