Hi people.


I have recently noticed some lines on the screen of my iMac. It's a early 2008 20" Alu IC2D iMac, 2.4Ghz with a standard ATI Radeon HD 2400 XT 128 MB graphics card. The lines are very faint, but my concern is that they may become worse. The seem to be around the left hand side of the screen-they aren't dead pixels either: they are more like a 'hue' running from top to bottom. I haven't been able to capture a picture myself, but have seen this online, and the ends of the arrow heads show these lines, which are nigh-on identical to mine:




Can anybody shed any light on this issue? Was there ever a recall or known issue? I have seen plenty of posts dotted around the internet regarding graphics card failures, and plenty of people complaining that when problems were posted on these Apple discussion boards that they posts were removed/deleted. What concerns me is that the problem may get worse, and I'll end up with a dead or un-functional iMac with no way to repair it.


A lot of the problem iMacs seemed to be from the 17" '07 to 20" '08 iMacs, with serial numbers starting 'W8xxxx', which mine does. If this is the beginning of the end, I'm disappointed as the iMac itself has only ever had light use as a home computer.


Any help appreciated,
