Vertical Lines - iMac 27 inch i7

acciogabby · Mar 18, 2013, 02:23 PM

I bought my iMAC a little over three years ago and am now getting many vertical lines on my screen. They are transparent and only can be noticed with certain color backgrounds. They occur over the entire screen and seem to be getting more prominent. I am not covered by apple care and the closest store is 2 hours away. Not wanting to pay the fee for the phone call, I will probably take it in when I am in another city visiting. Just wondering if anyone else has these lines, what was the cause? I have attached a photo to explain. Please help!

hi.

I got the same problem, and my iMac is a 11,3 (Core i7)

The video card is ATI HD5750 1GB

My mothers 2009 iMac has the same thing.

The lines are clear and they move.

Must be the lcd panel.

How long have you had it for? It's been about 2-3 months since we initially noticed it. I read that it could be the LCD panel or the graphics card. I am hoping that it's the graphics card which would be the cheaper option. I have the ATI Radeon HD 4850 512MB

My mothers 2009 iMac also has the ati RADEON HD 4850.

It showed up around 2011.

I just wanted to post my experience with this issue.

I brought it into the Apple store and the genius was very reluctant to actually finding a solution.

Her claims were "This is within manufacturer specification" I pointed out that the 8 iMacs at work didn't experience this issue. All 27" 2009 - 2011 iMacs. She proceeded to the back and said 4 iMacs except for 1 experience this issue.

I don't know if she wanted to actually help me, but i refused to accept the answer that this was within "spec".

Would love to get some more incite from other uses.

I am having the same problem with my 2009 27" iMac (Intel Core 2 Duo). I started noticing it soon after my 3-year Applecare expired!
