Michael says, "Here's another petition asking Apple to acknowledge a widespread manufacturing defect. This one concerns the problem with Apple's 17-inch Studio Displays that causes the top or bottom half to go dim, and the power light to blink incessantly. There is an ongoing thread on Apple's Discussion Board that currently has 371 replies, with 172 unique user names reporting the problem. It had 378 on Tuesday, but 8 of them, including one of mine, have since been deleted by Apple. I have spoken to Apple's Customer Relations regarding the issue, and they refuse to acknowledge it as a known problem. A flat-rate out-of-warranty repair is $458.95. A new display is $699."
(Thanks, Michael!)
