Display malfuntions but external monitor works fine, Graph. Card Prob?
Hi,
I started up my macbook recently and as it started up, horizontal lines appeared. Soon, these lines spread over the whole screen and slowly the screen dimmed till all the screen was black. On repeated attempts to restart the computer, as soon as I turn it on, the lines appear but quickly dim to black.
I connected to an external monitor and it displays of the separate monitor perfectly. Does this mean the LCD is defective or could it be a graphics card issue? I have checked the cable connections and they seem fine and undamaged.
Any answers are appreciated!
