White Line 20" - Apple Care Experiences?

Question

I'm interested the experiences of 20" iMac owners who've taken their "white line" monitors in for repairs.
Have the techs been receptive of the problem?
Do they treat it like dead pixels?
Is replacement based on the tech's opinion of how sever the problem is?
If you've had your monitor replaced because of the white line, how bad was it? If your desktop is set to black, was the "white" line 80% grey or 20% grey?
Did they replace your screen when they replace the power supply?
These are just a few questions to kick start the forum. I know once the white line appears, it's considered permanent on that LCD. I'm interested in taking mine in for replacement, but not if Apple is going to reject my request based on the severity, or brightness, of the problem.

Answer 1

Your description of the white stripe sounds just like mine. Soft feathered edge. Gets less pronounced as it heads toward the middle of the screen.
I'd heard somewhere along the line that the bad power supply was sending too much power to the LCD, resulting in this "damage". Once the power suppy was replaced, the cause is eliminated. The "damage" remains.
If you haven't had your power supply replaced, it will probably get worse. Given that you might only have 3 days left with the manufacturers warranty, I would probably take it to a certified repair center for a free diagnosis. You certainly bought it about around the right time for it to fall into the problemed category.
