I am running a 27 Inch 2009 i7 iMac which was having problems, The graphics card has been repaired before.
When I turned it on It had these lines on the screen.
I was told it was an LCD problem by a user.
I went ahead and ordered an LCD, I installed it and booted it up again and as you guessed the problem is still here.
Is this a graphics card fault or and LCD fault? (Second LCD)
I bought a cable to attach it to an external monitor and there is no problem on the external monitor.
