Display, flickering green lines
I have a mid 2009 17in MBP 2.8GHz.
The screen/display flickers with green symmetrical lines at random times. Its makes watching a video or gaming frustrating. They so up almost symmetrical around images.
I did find a temporary fix doing a google search.
If I apply pressure with my hand to the bottom of the laptop underneath the area of the left option key, it magically goes away. When I release the pressure it comes back.
Is there a permanent fix?
