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

Hi Dan,
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?

Can you post a few pics so we can see what you see on the screen.
Also have you tried an external monitor to see if the effect is on it as well.

All you need is a Mini DisplayPort cable to either a VGA or HDMI connection needed on your monitor. As example Mini DisplayPort to VGA Adapter
