Well couple of reasons. The time involved driving 90 minutes each way to the Apple Store. The fact that when I call they won't tell me if it is even in stock. Then, I don't want to get a screen that is worse than this one having dead pixels, dust and whatever. What's to say these new ones they are putting in aren't the same or worse. No one really knows yet that I have seen. So I'm not saying I won't do it but think I'll wait and see what people report.

So basically you don't let them fix it just because you Are not sure they can solve the problem .... Wtf ...

Your iMac, your call, but a very strange one in my opinion
 
I just wanted to rub it in that I have 2 Apple stores within 30 minutes.

Since I don't have my iMac yet (tomorrow is the BIG day), I have now brought the wrath of Apple Gods down upon me for being arrogant. I will end up with a machine that has yellowing, flickering, a high pitched squeal and an unstable hard drive. When I call Apple for service I will be told they are sorry, but they have simply run out of iMacs and will no longer be fixing/replacing. Thank you for buying Apple.

Two? Pfft. I have 4 Apple Stores(soon to be 5 with georgetown). :p

We have a week 50 i7 with the yellow tinge. Didn't do anything due to the problem not being fixed. Now that there is a reported fix and the fact the massive snow storm killed it, I will bring it in to get it fixed.
 
Let us know how the replacement goes

I would like to know how the new screen looks and if you look up the panel number in system preferences to see if it has changed.
 
Apple provided me with 'free' onsite repair. A local Apple certified technician replaced the LCD panel on my iMac. The panel is perfect. No gradient whatsoever. However... the end result is dust/lint behind the glass screen. I spent a good deal of time trying to clean both the panel and the glass, but it's pretty much impossible to get it back to its original state. So... I'm having Apple send a replacement machine. The panel issue seems to be resolved now. The repair process (I watched most of it, asked a few questions) isn't trivial and you pretty much end up with a refurbished machine. Your mileage may vary...

You have confirmation they are going to swap the whole machine out even thought the yellowing was fixed with a screen replacement???

Yep. That's it. Want to see if the panel they are putting in really fixes the problem before I hit the road again back and forth to the Apple Store. Just being patient. No real hurry. A wait and see.

This is what i was afraid might happen (dust).

it is not impossible you just need to use the right tools and do it in a methodological manner.

Combination of an air duster, Camera lens cleaning paper and solution, clean in overlapping strokes, spray off any lint left behind, and never touch the insides of the glass.;)

How can you see if this really fix the problem if you don't let them try ? :confused:

Well like I said I expect to let them try at some point but would like to see that it is working for others first. Honestly it saves me from driving back and forth. I would like to get this done on one trip and not have to repeat the process. I was already back 3 times exchanging the machine to no avail. A 27" isn't the easiest thing to cart around.:)

Yes. I've gone through two machines, one screen fix and now a third (and final) swap. I was offered a refund and then was offered another replacement. For the amount of money this machine costs (with extras), you are entitled to a machine that satisfies your expectations. A two week old machine with a screen replacement that leaves dust/lint behind (and my work area is quite clean and dust-free) is not what I paid for. If Apple didn't make such great products, I would've given up with machine number one or two.

Not to sound like a pessimist, but I would guess that a repair at the Apple Store would result in even more unpleasantries (I've had a few items repaired there and they never return in the same condition). It seems like Apple is trying their best to resolve this, and although I'm not thrilled with all of this, at least they're addressing the issue now.

I admire their efforts too. As long as they don't refuse exchanges if the customer deems to, then we're square.
 
Sorry, I didn't collect that information. However, I was told by Apple that it's the newer, non-defective LCD (it was shipped directly from Apple to the local repair shop).

Use this way and you will get the screen model number

go to system preferences > display > color tab > open profile > scroll down till you see "mmod" and read the model number of your screen

So, it is not a new screen model or new part number. Interesting. How come they can solve the problem with the same panel as my iMac 27 week 5?

Wow, big deal. I have 5 Apple retail stores within 20 minutes from where I live and I'm only 15 minutes away from Macworld in San Francisco. There, I just had to rub that in. :D

Because it was just a bad batch of the panel. LG fixed the issue and continued production.
 
question: by changing this panel, will the backlight bleeding be fixed (or changed) as well? or does it not affect that part of the screen in any way?
