Green lines on lcd, external monitor is fine
The problem looks like this:
Vertical green lines all over the screen. But no problems with an external screen. Do I need to replace the screen or the display data cable?
I think that the problem of the green lines is caused by this problem: http://support.apple.com/kb/TS2377?viewl...
But the outcome Apple software test by a apple repair man said that everything was fine with the Nvideau processor. So I did not qualify for the recall.
I cleared the macbook inside of dust, especially the fans were full of dust. And put some new thermal paste on all the processors.
At this time i only use the macbook for web surfing and email. He is retired and don'tt need to perform any heavy rendering work. And now he is working almost problem less with occasionally a green screen for some minutes.
