Hi, I have a 2011 27" iMac and the backlight in the lower left hand corner is shot. I've already got the panel replaced while it was under warranty. Now the iMac is having the same issues and is no longer under warranty and a Mac reseller tells me it will be about $600 to repair it. Is there anything I can do to get the iMac fixed for cheap or free or even replaced? I'm a graphic designer and I'm disappointed that I can only utilize half of my screen right now.
