Hello,
I have a 2009 LED 24" Cinema to which I hook my Macbook Pro (also 2009).
Today, I come to my office and the LED has intermittent vertical lines
appearing, about 1/4" wide and 1/2 the screen high. Sometimes the screen
goes blank (black in fact). All these disturbances last a fraction of a second
and come up about every 3 or 4 seconds.
Is there a way to know if it's the screen or the card or the cables before
I have to take everything to the Apple Store?
My Macbook pro screen works perfectly.
Thanks for any help
