I used the wrong search terms on this problem. I should have included "flickering" in the string of terms. That opened up a whole can of worms. It seems this problem started in '07 with the MacBooks and there are hundreds if not thousands of posts that never seemed to be resolved. The optimist in me thought that apple would address this issue, but here it is June 2011 and I have found no info on the cause of this issue. You would think that one of those high paid techs from apple would isolate the problem by now. After all they have all of the test points! Then the pessimist in me took over and I have realized that apple is just letting the ball drop on this problem figuring that people would just buy another one or spend additional money trying to fix it. Apple makes billions selling these so why should they give a damn if they break. I feel lucky that mine lasted over two years. Many had the problem right away and even though those were under warranty their replacement ended up doing the same thing. Others went through the repair process from the local authorized dealer and the fix proved ineffective. Others who were out of warranty threw money at it never to get the problem resolved. So, I'm here to ask if anyone knows if this problem has been addressed by apple or not? Or has anyone independently figured this one out? I've used apple from the beginning and still have a pismo laptop that works and runs OSX fine. Let's see, I believe those were made in cupertino. If anyone is interested in a description this problem see my previous thread.
