Attention new MBP owners: Please perform this Yellow tint test

[jjahshik32]

Thats gross!!

I have a 2.4ghz SR mbp from last nov. and no yellowing, Its panel number is: 9c66. I think that panel is perfect, as the lg doesnt have any yellowing either but the quality on colors look very bad on it like it was fake or something and the samsung as it did have the yellowing the colors looked vibrant and very nice.

But the 9c66 has both no yellowing and rich colors! Yes, I've exchanged over 10 times literally... I'm the sr mbp master.

 

[markrivers]

but what if you're MBP is a refurb? how do you exchange it? can you go the apple store as well?
10 times.. wow! that's a lot

Cottington,

Do those pictures reflect what you see with your eyes, or is the camera white balance a little off? I've seen yellowing, but THAT is the absolute worse I've come across! If that reflects what you see, and even if it's just a fraction of what the pictures show, I would immediately have apple replace the display. With that kind of defect, they won't argue with you at all and anything would be better than that. Just go do it - you'll be so much happier. Just my very humble advice....

I think the pictures do a pretty good job. The white balance is probably a little off, but you can tell that, even if it weren't, the bottom would still be yellow. If I take this to the Apple store and if they see what I see and if they agree it's a problem, do you think they would replace the actual screen or swap the entire unit?

Since it's past the 14 day return period, they'd replace the screen/display assembly rather than replace the computer. Usually take 3-4 days, sometimes faster depending on if your apple store does its own repair or need to send it to Texas to their repair center.

I don't think you have to worry at all about them seeing the issue. Also, it's not like they've never seen it before...

Yep. Past the 14-day period, no matter what the problem, I'm convinced (from experience) they would rather replace every single system component twenty times each before just replacing the damned unit. This is one of their policies that absolutely drives me insane.

Did you have to get your screen replaced? Are you using SR or Penryn MBP now?

 

[Joko]

Here are some unaltered pics I took in a dark room. Some were from different angles and distances. The yellow band at the bottom is noticeable in every picture.

It's the 2.2 SR with the 09c68 Samsung display. I went to the Apple store and got it the very day they were announced last June. I noticed the yellow right away. I read online about how others had seen it too, but I guess I thought I could live with it, so I didn't return it. Now that the new models have come out, I'm anxious to see if there is a similar problem. I really can live with it, but I feel I shouldn't have to for the price I paid. Like others have mentioned, when you know it's there, it bothers you. I am within the 1 year warranty, but I don't think Apple will respond very well to any sort of complaint.

[NO. NEED. TO. QUOTE. ALL. THOSE. IMAGES.]

wow thats really gross and disgusting, i vomited in my mouth a little.

 

[cms2]

No problem here. I've run this and other tests, and always felt a huge sigh of relief after "passing" the test!

 

[Paix247]

no yellowing here, but I do have a very annoying BUZZING sound when I use anything graphics intensive, and when I scroll web pages... I think its a bad graphics card. I'm bringing it in tomorrow.

Does anyone else witness the same buzzing issue? Glad to see that the yellow tint seems to be consigned to history

I'm eager to get more reports about perfect LED screens. I'm considering a refurb SR 2.2, because I don't think the improvements are worth $450+, but if the new model is 100% perfect screen without yellowing, I'll fork the money over anytime.

I'm in the fifth ave store and looking at the new ones. The 9c81 version seems slightly yellowish but very slight. It also has quite noticeable bleeding at the bottom. The 9c83 seems perfect with little or no bleed and very even illumination and no discoloration. The one they have here is glossy and maybe looks like it has a liitle grain compared to the other. I would be very excited to have the 9c83 version. Just my observations - may or may not apply to other units...

how many 9c81's have you seen on the new MBPs? Many here seem to have recieved the 9c83's, hope those are the standard ones.

I've only seen two of each so it isn't in any way representative- just some observations that's all. The 9c83 is really nice and when I went back to look again at the other model it has an overall yellow cast rather than just the lower part so it is possible that you could calibrate to make it look good. The bleeding can't be changed though.

Ok, thanks for your observations. Ordered a base 2.4 with 250 GB HDD this morning via the web, can only hope to recieve a 9c83 screen...was the bleeding the same on both 9c81 screens?

One of the 9c81 screens was actually noticeably better than the other in terms of bleeding , so perhaps the bad one was unusually bad? Let's hope so, and let's hope Apple has actually dealt with the yellowing problem. I'm pretty sure that the very slight yellow tint I saw can be calibrated away too. Definitely liked the 9c83 better though, which I'm surprised about given that I usually really like the LG displays. Anyway...time will tell which displays are good and I hope you get a good one!

Ok thanks, it seems like the "classic" yellow tint issue of the SR MBPs has been fixed one way or the other. Of course I will call Apple straight away if I recieve a faulty screen of any type...fingers crossed, I would have bought it from the Regent Street Apple Store but I wanted the 250 GB hard drive option, so I went for a custom made job

[Mr. Funsocks]

Also I ran the test and saw the very, very almost unnoticeable white yellow. Doesn't bother me at all. It can only be seen on the bottom white bar and never seen during normal use. It's almost impossible to notice when the test image is on it to be honest. I'm sure a decent calibration can get rid of it even on the test image.

EDIT: I almost had to force myself to see it. Some people might not. I could be imagining it but I doubt it. It's ever so slight, I wouldn't worry about it considering the fact that my display is considered to be the better of the two anyway.

I had LG 9C67 in my SR MBP, and it was perfect. Now i have 9C81 Penryn MBP - it is even better. No yellow issue, nice grey color, very good gradients. Btw, i've seen some Samsung screens. Try to run a gradient test(or try green/red gradient in photoshop) and you will never want to have this screen. Samsung can't reproduce 32bit color

This poster is ABSOLUTELY correct. I also purchased the SR 2.2 in June right after they had come out (I didnt realize this at the time as I had fancied a MBP for over a year and decided to buy at on a whim) . I also had a Samsung screen. I thought there was an issue from the time I saw it but lived with it. The MBP turned out to be a wicked lemon with issue after issue. It was replaced in September with one that had a LG screen that was PERFECTIO, as was the MBP.

This issue is real... it was and may still be with all the SAMSUNG screens. I believe the folks claiming the issue on LG screen may be these optical illusion folks. My theory is that Mac owners are eccentric to begin with and this type of stuff brings out their Nerosis....

[Goodbye Dell]

Just opened my new 2.5ghz mbp (and first mac ever) and to my dismay there is a slight yellowing issue on the bottom 1/3 or 1/4 of the screen. I noticed it as soon as I turned it on. I did the test which made it look even worse. There is also some bleeding in the top right corner. I'm going to go back to the apple store later on today. Thankfully it's only 15 mins away. Btw the model # is 9c82. Haven't seen this model mentioned on the forums yet. Anyone know who makes it?
