Screen issues after Genius Bar repair
I had to have the ODD replaced in my 2010 27" iMac. The Genius Bar experience was, erm, an experience.
I got my iMac back today and, after turning it on, discovered what appear to be dead pixels on my screen. They definitely weren't there before I left the machine with them. From briefly looking around the web, it appears it may be (i.e. I hope it is) dust that's trapped behind the screen. Surely Apple have the equipment to allow them to prevent such occurances?
Should I demand they do the job properly, or am I expecting too much?
Had I ben told about this before hand, I might not have opted to have the ODD replaced (as I only did it because it's still under warranty).
iMac, Mac OS X (10.7.1)
