    I've recently had the same issue. I would classify my line as aqua since it's a very light blue/green.

    I'm running the very first year of the Intel Core Duo. 10.5.8. Am I looking at signs of logic board failure?

    Verticle line on screen
    I have a 2007 i-mac with tiger. The line appeared yesterday when they updated the computer with I-tunes, Quick time and intel security something or other. The updates did not take properly because it said there was someone else logged in on i-tunes--which was not the case???? The line is acqua-green and begins where the H in help ends on the upper bar. We have no idea what's going on or how to get rid of it. Everything else appears to be working fine.

    I take it that's not a good thing...

    I'm getting a Mac Mini anyway, but could I sell my iMac with that problem for anything?

    A 2007 iMac is still certainly worth something!...but of course that vertical line will certainly reduce the value.

    You could try connecting an external monitor to your iMac...and see if the problem exists on the external monitor as well. Then you could either keep the iMac (working off the external monitor)...or sell it, informing folks that the main monitor has the vertical line issue...but state that if an external monitor is used, everything is fine.

    Hope this helps,

    In this post you mentioned that the problem with the iMac started when "they" updated the computer.

    Who is they??

    Maybe the OS got messed up somehow during this update. You might want to try reinstalling the OS before you consider this computer "no good", and selling it.

    I have had this problem on laptops before, they usually mean the LCD display is going bad, the lines usually get worse, although I haven't seen this as an issue with GPUs myself I do know that is also a possibility.Do what pigoo says and try an external monitor, that will tell you what the problem is. unfortunately it is highly impractical to replace the iMac LCDs, but the graphics card is easier. Neither one is cheap, however.

    The reputation system is a part of this board... that is a part of pigoo's signature.

    I received & replied to your PM...and I'm posting here as well to help with the continuity of the thread.

    That line appearing after the update sounds way to coincidental to be anything other than being related to the software update.

    If I were you (and if I had the same problem) I would do a fresh install of the Mac OS.

    One other thing you could do, is try booting the computer with the grey/silver disks that came with your computer (I'm assuming you got this computer new).

    When your computer "boots" from the disk...don't do the reinstall yet...just look to see if you get the vertical line.

    Hope this helps,

    The reputation system is related to this website...it is not something "Mac" related. Give this a read if your interested:

    Buying a new LCD display or a new graphics card. The good graphics cards are in excess of $100 (Sometimes in excess of $200), and I'm not sure about the LCD's but I have seen some laptop LCDs go for more than $150 and that is not something I would trust myself to install one properly, it is not a job for the inexperienced.

    Also, I think some iMacs had the Intel GMA 950 integrated graphics, which is not replaceable, in which case I have no idea what you could do to fix it. It depends on which one you have exactly.
