With my serial on the website, I get this message:

O OH!
	The Serial number you entered (C02J80URF51R) is either of a (sofar) unsupported model or incorrect. Please try again or submit the information by clicking the button below. (If you entered the serial number starting with an 'S', try it without.)

That is correct. Samsung/week 34.

As for your serial not being recognized, try checking it there. Perhaps you'll get more info.

Weird ! I checked five computers total, 3 with LG and 2 with Samsung, same numbers that I mentioned...

 

You have a Samsung week 34, right ?

 

I have a new LG week 35 and it's completely different in terms of colour and no image retention so far.

So you are saying you could not calibrate either screen properly using a puck?

I've got my fingers crossed for you Dr. Sly! Hopefully you don't experience any image retention on your new rMBP. Maybe the issue has been solved. By the way, how is your display "completely different in terms of colour"?

I forgot to mention, for the last several weeks I've been in contact with a very nice lady from Apple Corporate Executive Relations. Her and I have emailed back and forth several times and she's also contacted me by phone at work, including yesterday. She told me that Apple will soon be making an announcement on their web site regarding this issue, hopefully within the next week, but she can't promise 100% on the timeline. I do really think they're working on this. She never gave me any lame excuses about IR being within the spec and she asked me a lot of questions (i.e. How long does it take for the image to be retained? How long does it take to disappear afterward?). One other thing, I think I'm getting a bit more attention from her because of where I work. I work in the "video" systems division of a huge multi-national company. So, whether it's warranted or not, it seems that my feedback is possibly carrying a little more weight than, say, a first year college student. Again, I'm not saying that this is warranted, but that does appear to be the case.

Anyway, hopefully Apple will rectify this soon and we can rebuild the strained relationship a lot of us now have with them, especially after what some of us have had to go through.

This is a later model than mine. I hope that yours hasn't got any IR. That could mean they are resolving their issues. I keep my fingers crossed for you!

Right, thanks, I believe I already have posted that info on this thread then.

Here it is again:

Production week: 34 (August)

Hello Canuck,

My 'first three' LG screens (original on the stock rMBP I am returning on Monday and its two replacement displays) were so YELLOW it was beyond bearable. In fact, all the greys and light blues were yellowish whereby it was a major distraction whilst reading on the web or from the usual Cocoa interfaces.

Pictures were neat looking of course, since the display 'color temperature' was so low, it gave green/red/yellow images a very warm feeling. I of course could not accept the huge discrepancy between my other displays and those ones. Problem was, even with calibration, everything was off.

Not that it matters nearly as much as the actual problem we are having, i.e., image retention (I restate this everywhere so that the Apple folks who are reading sporadically our messages don't get confused as to what is at stake here, and I know for a *fact* now that they are reading this thread...)

So my new rMBP, which I also acquired at the Apple Store Montreal yesterday, is so far so good for image retention (I know, I know, could happen any time in the future ! But it really, really looks different). I'm testing it twice a day.

This newer rMBP with a newer LG screen (production date) is on the white-pinkish side, not white-blue like I prefer them (i.e., any Samsung rMBP grrr), but I will try to calibrate it later this weekend. Don't have a color spectrophotometer, but I'm pretty sharp with displays considering I had to look at neuroimaging data for so many years.

It's *slight* pink, not *horrible* yellow, if you know what I'm sayin'...

That's significant, because this IR issue was pretty well known by the middle of August when this display was made. I seriously doubt they would knowingly send out an LG display at that point without testing for the IR issue. However, only time will tell. Keep us posted.

Well, you are luckier than I am, I got someone from Austin, Texas (see below) who told me that:

1- he discussed this is issue and it's not an issue because the display is working according to 'Apple's specifications'

2- they won't replace the display anymore, since argument in (1), plus I did it too often !? already

3- they can't replace it by another machine with a Samsung display because Apple doesn't do that

4- they can't compensate me for any of my troubles and loss of work time/money because Apple doesn't do that...

So I told him I'm returning the old rMBP soon for a full refund (why would I keep a computer which I paid lots of money for and which has a horrible display?) and he he didn't really reply to that.

Every time I mentioned how unacceptable the display was (yellow, image retention) he said it was within Apple specifications (how could that be if he and his engineering buddies never had any of the displays on hand), and I replied that 'user experience', 'common sense', and 'non-subjective perceptual criteria' could easily resolve the issue as being a subpar display...

Bottom line is, put any two LG and Samsung screens side by side, they look NOTHING like each other. Put my newer LG screen side by side with the three older ones, nothing alike either...

(and no image retention !)

Forgot to mention, the gentlemand was from:

Corporate Executive Relations

Apple

Wow, when you think about it, this means it was manufactured between the 19th and 25th of August !?

Sounds like I'm in the same boat as you Dr Sly, in terms of our current displays. Could the issue really be somewhat resolved?

Seems like it!

On another note, I checked some website (can't remeber which one) for serial crossreferencing and manufacturing date, and it gave me week 35.

Then some other website (http://www.chipmunk.nl/klantenservice/applemodel.html) gave me week 34...

Not a big deal, just questioning the accuracy of those databases.

Also, the abovementioned 'chipmunk' website declared that my rMBP came from:

Factory: C0 (Quanta Computer (Susidiary = Tech Com))

Peace out.

I'm guessing you don't have one or both of them anymore.  How long did you have them?

Hi bjiibj, no I still have the 2.6/16/256 MBPr , don't have the 2.3/8/256 MBPr as I negotated a upgrade when they open the base model to all options. 

Still doing OK with the week 33 LG panel.
