Why is my LCD display has some blue lights when it moves?
My MacBook 2GHZ Core 2 Duo LCD display has some blue lights when I move the screen.
In some positions nothing happen but in 90% of the positions, it is there, blue mainly on the dark colors of the images.
I have been checking and couldn't find anyone with the same problem on the net.
It seems to be just a bad contact somewhere, do you think that I have to change my LCD screen? That would be a pity.
To isolate the problem, hook it up to an external monitor. This sounds like a cable problem. Please give the last three figures of your serial number (located in the battery compartment) so we know which machine you have.
Could not get your video to play. Am assuming a beammer is an external monitor. At this point I would replace the Display Data Cable: MacBook Display Data Cable
