The person who owns and operates the iMac is a heavy smoker so I was thinking maybe that's the issue, but I want someone's expert opinion on what this could be caused by and how to fix it if possible. It doesn't affect the viewing experience, but it shouldn't be there and I am wondering if an underlying hardware issue may be the cause. It has been bought a year ago and used the same time period. Pictures are attached. Thanks for any help!

Just to help some of us that can't see what you are describing, including me FWIW.

Can You take the pictures and put circles or boxes around the problem or maybe an arrow pointing to the lines?

 

Thanks

Roger

I'm sorry, I just don't see what you see.

 

I wish I could help on this one. Does the problem show when the screen is on? For example when the screen is white or some other color does the problem show better?

The only thing that I could think is that something is getting under the glass on the iMac screen.

 

I suppose you could try taking the glass off and try cleaning it.  There are many instruction guides for how to do so.  I tend to use http://www.ifixit.com/ for instruction guides when I "tinker" with my Macs.

Hi guys, thanks for the replies.

 

I guess I will try smax's suggestions of cleaning the screen.  But I wanted to know if anyone knew what could be causing this.  The person who uses this Mac smokes a lot, but I am not aware of how the the smoke could get inside the Mac's screen.  Perhaps through some USB ports or speaker openings or something.  I guess I'll have to be content with this "educated" guess lol.

 

rotor, what I was talking about is the grayish "cloudy rays" you see on the screen separated by the black lines of the parts of the screen that are not "clouded".  It's kinda hard to explain but if you look at the pics again I'm sure you'll know what I mean.
