Something loose on logic board controlling display

So, I was wondering if anybody else has had a similar experience here. My displays some veritcal lines, so I give the case a good tap or jiggle around something in the USB port and it goes back to normal for a bit. Any suggerstions? I also recently had my logic board replaced (actually twice in a row). This started after the second time. Here are some images to give you a better idea.


My system setup is i7 @ 2.2GHZ and

AMD Radeon HD 6750M 512 MB


Late 2011

I think I might have fixed the problem...


I noticed that the probelm went away when I depressed a particular part of the case (near the tab and tilde '~').

So, took of the case and saw that there were depressable contacts coming out of the logic board that should be touching the case. I disconnected the battery and took a multimeter to see if the contacts were connected... they were! So, I cleaned the parts where it looked like there should be contact made the case and viola! No more lines.


I guess the problem was, contacts on the logic board that was supposed to be touching the case were not.... I think.
