MacNN reports that there are a growing number of iMac users that are having some pretty serious LCD screen trouble. The trouble seems to be that the iMacs are “showing a number of artifacts that include single-pixel lines spanning the length of the screen.”
This discussion thread features over 80 posts about the issue, and since most of these iMacs are over a year old and have just come out of warranty, users are being quoted prices of $700 or more for the problem to be corrected at Apple stores.
If this issue continues, you can surely expect a class action suit of some kind to be filed (update: Let me be clear here that I don’t think anyone SHOULD file a lawsuit over this – just that I won’t be surprised if it happens.) , but hopefully, Apple will address the issue before it comes to that.
