Hi. I need the help of my MacRumors friends. I'm sure this has been discussed, but it doesn't hurt to bring it up again. Anyway, I'm having a problem with my 2007 20" iMac. As you can see in the picture below, vertical white lines are beginning to appear on the iMac. Anyway, I was at an Apple store, so I decided to ask a Genius at the Genius Bar about the problem. He said that it may either be a bad LCD or a bad logic board that is causing the lines to show up on the screen. Replacing the logic board will be over $600, so I'm trying to avoid that.. Do you think Apple would fix this issue for me for free or at least a cheap price? I do not have Apple care for this iMac, and even if I did, it would be expired already. Thank you and I appreciate your help!
