5 pink vertical stripes, new video card and screen tried,
Hi I have replaced both the video card [brand new] and the screen but the problem has not gone,
Is it the logic board that needs to be replaced? Any way I can confirm this? Thank you
Actually to be more accurate, after repeated rebooting the the iMac started working normally,
I then did the hardware test and all passed but now after almost 3 weeks it has stopped working with the same typical 5 pink vertical lines as before,
I have not connected it to an external monitor. Do I need a special cable for this, Thanks again!
Is this a good question?
