    Imac display issue, like wires behind screen casting shadows
    First off, i have been coming here for the great info for awhile, but never needed to post. I'm hoping some one might lend me some good advice on a display issue. I have what looks like a shadow of a wire behind the display of my late 2009 iMac. I have recently noticed it, and it's kinda bugging me. It's not like a persistent burn in from an image. But it is persistently reminding me it's there. Could this be some hardware. It looks like a water mark on the screen running up and down squiggly line about 1/4 thick, 8 inches long. Thank you in advance for your thoughts.

    Can you take a picture and post it? Does it show up in screenshots?

    What Chas was asking is if it still shows up in a Screen Shot. To do a Screen Shot in OSX you hold down Command+Shift+3. It will save to the desktop. Do you see the same pattern in the Screen Shot?

    sorry it's not in the screenshot, viewing on my monitor, which is probably faulty.

    Not the video card then, it's the panel.

    such a shame, I love this thing. It's like having a hot gf with a birthmark on her cheek. Still not going to dump her. But I like to sell it and upgrade, like my ex wife.

    My NEC 2690 exhibited similar artifacts and it was internal separations of some sort. NEC replaced the monitor.

    Sorry to see you have a similar problem.

    thanks for the input. I think it is a hardware issue. iMac is a good idea, but this form factor inherently was doomed for failure over the longterm. It's only been 2 years. Next I think I getting a macbook pro.

    My iMac G5 iSight LCD is still like new after 6+ years use and most of it 24 a day. Your issue with the panel is at least to all the forums I have read, rare.

    true, only thing that has changed is that I bought a set of alexis M1active studio monitors, which have been to the left and right of my monitor (maybe the are unshielded, but haven't heard that being an issue sine the early 90's) in the past 2 months. That being said, I noticed the the yellowing in the bottom right hand corner way before this and had settled on that issue, but it is a known fact for these models. I have sensitive eyes, ears. still love the mac.

    So do I my friend and my display is perfect. So is the one on my 20" 2007 iMac.

    There was one iMac that had some panel issues. Most were fixed by Apple for free if I remember right. Yours is probably that model.
