Light Bleed, Stuck Pixels, Small Hair Behind Display Glass

Today I received a new 15 inch MBP as offered as a replacement due to warrantee issues on my previous machine. The first thing I noticed after booting the new machine was significant light leakage coming from the bottom of the display as well as multiple dead pixels (black in color) and some dirt or hairs stuck behind the displays glass. Will I be able to get this new machine swapped just as if it was a new machine? I know I have a brand new warrantee. I emailed the customer care agent I was in contact with but I'm sure I wont hear back till tomorrow. Any help or advice would be appreciated.

hello,
i am aware of cases where apple has replaced computers for things like dust/dirt behind the screen as well as dead pixels and light leaks. the basic thing with getting a machine replaced for these reasons is that it effects basic use of the machine as per the DOA section of the agreement (on the apple site). i think in this case you can say that it effects your basic use of the machine because there are three issue that prevent you from seeing your display clearly.
you could also request a replacement for customer satisfaction reasons if they do not agree that it is DOA and just say that you are not happy with the quality of the unit and that your other unit also had issues.
in order to qualify for a DOA you must report it to apple within 30 days of getting it, so i would call right away and request a replacement.
regards,

Light spots (not pixels, regions) on PowerBook displays

Be forewarned: This includes a lot of conjecture on my part.
We're developing some software and need to get some older PowerBooks for platform testing. We only need these things for a few weeks (OK, maybe months) and then would probably sell them once done with them.
In any case, we've seen a fair number of PowerBooks, particularly the 15" models, showing up on eBay with "light regions." I say "regions" because it really doesn't look like it's a typical failure related to electronics. When I've seen displays go bad they most often seem to show things like lines running up and down and/or across the display, pixels that won't change color, and blocked regions showing combinations of the two I've just mentioned.
These problems seem different in that they really look almost like someone came across the display and airbrushed it in a few places to make it look lighter or darker in the specific regions. The colors change on demand, but the areas showing spots are always show the same type of color shift. For example, if you turned the entire screen a solid medium blue, these areas would look like someone came along with an airbrush and sprayed the regions showing this light blue. If you turned the display red, then the areas would look like someone came along with an airbrush and painted them a lighter shade of red in the exact same areas.
What I'm guessing is that in the LCD assembly there's a diffusion sheet that was probably bonded to the back of the LCD panel so the light source would allow the LCD to appear to have even brightness when initially manufactured and displayed. My theory is that either through heat, abuse, or just time, that the diffusion sheet has begun separating from the back of these LCD panel by bubbling up, causing those areas to capture more light and hence cause these "lighter regions" to appear.
Here are my questions:
1. Does this theory hold any truth, or is it a bunch of hogwash?
2. If this theory does hold true, I would think that the diffusion sheet could be reattached unless there's a layer of glass over it. Has anyone tried this?
Thanks.

This should be covered under warranty, provided that it is not user caused.

Dust behind display glass

My MacBookPro5,3 15" display has acquired dust speckles BEHIND the glass of the display. So is this common or normal?

I had to go through three 15" Macbook Pros before I got one that didn't have crap behind the screen. Good thing I brought it in before the 14 days, or else I'd be SOL (per Apple "Genius"). I'd bring it in ASAP before apple makes you keep it.

Small hair/dead pixel behind screen 10 weeks old MBP

Hello,
I have a 10 weeks old MBP and now I was browsing the web when I noticed a very small hair behind my screen
it's aprox 2-3 mm in length but it really annoys me because of 2 facts
It's in the centre of my screen
My MBP is 10 weeks old!
However it also could be a line of dead pixels.
I already read some threads about this and most of them say that I have to go to the Apple store,
but I live in Belgium? I don't know if the service is the same as in the US?
thanks!

Hello Michiel0lb,
No, I'm sorry but I can't be that positive. I don't use MBP, I have never seen their guarantee and the interpretation of a fault has to be with the examiner ... in your case, Switch. That said, if the fault is visible any decent company would want to see you satisfied whether it means cleaning, replacing the screen or the whole MB for that matter. 10 weeks is not a long time and Apple is a decent company.
I can (just) make the fault out though I'm sure it is more visible in reality. Be sure to approach Switch in person and phone first to confirm they are able to handle a warranty matter. Re-sellers often have facilities to repair on the premises or they will send the machine back to an Apple base if the matter is serious. But if asked when you phone, don't say any more than your screen has developed unusual marks that could be faulty pixels. For your own satisfaction you must ensure it is examined.
Post back with your findings ... and good luck,

17" MBP Display - TN or IPS? - Light Bleed?

I've had a 15-inch Unibody MBP since December and am not thrilled with the display. It apparently uses twisted neumatic (TN) technology, as it has a very narrow viewing angle. And as has been described in other posts, many individual displays have a problem with light bleeding around the perimeter.
I'd like to know how the new 17-inch MBP compares. I know it has a greater gamut. But does the viewing angle suggest it uses TN, IPS (In-Plane Switching), or some other technology? And have any individual displays exhibited the same kind of light bleeding that has plagued the 15-inch models?

EWW: Thanks for elaborating. (Your full message isn't displaying, but I received it in the email notification. Don't know what happened to it.)
Your point is well taken, but after talking to an Apple rep, and then noting the number of posts from people who got multiple replacements with the same problem, it seems an uncomfortable proportion of 15" MBPs recently shipped are in this condition, to some degree. And for myself, far from the nearest Apple service, repair or replacement is lengthy and inconvenient.
I fully intend to have the problem corrected. But there's no hurry.

Are these dead/stuck pixels? Glass damage? Or something else?

Can't quite figure out what this is. Are they stuck pixels? Dead pixels? Eyelash? Damaged glass? Something else?
Because of the glass pane between the display and the screen, I can't tell how much the glass, if any, is potentially refracting colors of the pixel below. I've tried running stuck pixel software to no avail. The display is out of warranty, so it would cost $400 for Apple to fix. But if it is simply in between the glass and the display, maybe there is a cheaper fix.
It is only visible on a lighter background. On a black background, it is not visible at all. I would assume if they were stuck pixels, they would remain visible on a black background. But if it is a small crack in the glass, it would make sense that it would only be visible under certain conditions.
Please let me know your thoughts.

My initial reaction to that picture is there's a defect in the display. It doesn't look like a video card defect nor something caused by some object under the glass to me.
You don't say which monitor that is. But if it's an imac-like monitor (or the recent crop of apple stand-alone monitors). and you are interested in removing the glass to look under it, there are instructions on removing the glass covering the screen. iFixit has some. And if you put something like "remove imac glass" into google you'll find a whole bunch.
One final thing; your sig says you are using Lion. Did you see this problem with Snow Leopard. Anything involving lion I hold suspect

Stuck Pixels + Dust

I have had my iPod for 4 months now and have had 2 stuck pixels since i got it, they have only just started annoing me as i have now started watching movies.
Added to this i have quite a large amount of dust behind the screen mainly in the top left corner, there are also one or two coloured particles whitch i am unable to identify, they are the size of 4 pixels and still appear wjen the screen is off, clearly the seal is broken or somthing along those lines as i have allways kept my iPod in an Apple iPod sock from the day I got it. I feel rather dissapointed by theese factors as the Multi-Touch display is the main feature of the iPod touch. I would like advice on where to go next... Should i visit an Apple Retail store os Send it in Online? I would also like to know if a refund is a possibility because as old phone has now ceased to function, i would like to get the iPhone... Would this be possible and how could i do this.
Thanks for Your Help Phil.

Phil,
There isn't much you can do about returning it or trading it. Apple gives you the 30 day grace period after purchase to return for a full refund and clearly 4 months is beyond this period. My suggestion would be to take it in, have it replaced (as it is still under warranty), then try and resell it on CraigsList or eBay.

X220 with backlight leak and stuck pixel

I just ordered x220 from lenovo. I recived the box yesterday and found my new thinkpad had many backlight leak and 1 stuck pixel at the center. I am very disappoint with it. Can I return it, change to new one or send to lenovo sevice center in thailand to change my IPS display.
I ordered it on 5/26/11. My friend in USA passed it to me on 6/6/11 then I recieved package in Thailand on 6/10/11.
This is my backlight leak.
http://imageshack.us/photo/my-images/840/img0056yz.jpg/
Unfortunately I can not take stuck pixel image.
I hope lenovo will help me fix this problem.
Thank you.

welcome to the forum!
the current policy is that a display must have three or more dead or stuck pixels to be considered defective.   one is simply not enough.
http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-69856
regarding the backlight bleed, it looks normal to me for an LED notebook panel.   i could create a condition where even $5000 IPS graphics displays show some sort of backlight bleed on a black background with brightness at full power.   no display is perfect in this regard.   my X220 IPS panel has a slight amount of bleed under the right conditions but is only noticable 1% of the time.
if this is unsatisfactory, you may try contacting lenovo support in thailand at 1-800-060-066 or 66 2273 4088 between 8AM and 5PM monday-friday.   however, please note that they will likely refer to the same pixel policy above.   whether or not they will make an acception due to the location of the stuck pixel is up to them.
also, i've removed your second account "eldonler" as we don't allow members to have more than one login per our community participation rules.   thanks for understanding.

Dead pixel or stuck pixel??

Hi,
Have just received my Core 2 MacBook, I'll cut straight to the problem.
There's one problem pixel on the display. A little way below and left of the centre of the screen. The pixel is black when on a white, red or blue screen, however the pixel is capable of displaying green, i.e. when I pass a green panel over it, it appears as normal.
Does this indicate that the pixel is dead, or merely stuck? Or to ask my question in another way, will the Pixel Widget (or similar flashy thing ) have any effect on it?
Thanks in advance.

Hello
I had 6 dead pixels on my macbook pro screen. I was quite annoyed about it.
After a huge research I did find solution. At least you can try it is for free
It is a small Jawa applet which flickers and can unstuck pixels.
I had 6 dead pixels. After using this flickering applet for 10 minutes 4 of the pixels disappeared They were in the center of the screen.
The last two are placed on the top of the screen. On the top dock where the blue apple is. Fortunately there is no way I know about how to hide this dock. Therefor stuck pixels remain. (if you know how to get this flickering applet over entire screen please let me know, the videos on the website did not work for me)
Anyway check this website and good luck, Hope it helps.

Stuck pixel or dead pixel?

I have a question I'm hoping someone can help me with. I recently purchased a macbook off of craigslist. It was purchased by the original owner in February so is still under warranty. A few days ago I noticed a single dead/stuck pixel in the lower left part of the screen. Not sure if it has always been there and I just didn't notice it or if it just popped up. On a white screen it appears slightly reddish, on a red screen it's not visible, on a blue screen it's not visible, and on a green screen it's black. My first question is whether this would be a stuck pixel or a dead pixel? And secondly, do I have any chance at all of this being fixed under the warranty? I don't have a Apple store in my area or I would take it in there to get looked at, so I'm relying on you guys for support. I've tried using the various "stuck pixel fixer" images on the net that flash colors, nothing seems to work. I tried lightly massaging the pixel, but am not really crazy about putting too much pressure on the display.

That's an odd combination of appearances. If it's not visible on red or blue then I would assume it's a stuck pixel rather than a dead one (which should appear 'off'/black on every background colour), although it should only disappear in sympathy with the colour on which it is stuck (i.e. either red or blue, not both).
You can phone Applecare and ask them about it, but I think you'll find they'll only do something about it if you have a certain number of 'pixel anomalies'.

Best of luck with it.

Dead or stuck pixels?

Hi
I got my MBP a week ago and I didn't notice anything worng with it, except for the known things like "whine" and "heat", but I'm OK with that.
Today I noticed a display issue, something like a dead pixel or whatever It might be called. I could have been there before, but I'm pretty sure I would have noticed it as I can see it pretty clearly now when browsing the net.
I ran a pixel checker and saw another one, the same appearance! But a bit further away so I don't notice it when surfing.
I have an external TFT monitor which also has one of these, the same kind. I Googled a bit now but I'm not sure if it's a stuck or a dead pixel. Stuck pixels seem to be fixable with some flashing movies, if you're lucky, but shouldn't be used too much as they might cause new stuck pixels (?).
Anyway, I read DEAD pixels are black. My pixels are not black, but they aren't of the same color all the time. Depending on the angle I view them from, they "blink"/change color from red,green,blue, they aren't the same all the time.
Do I have stuck or dead pixels?
Thanks!
edit: But it looks like a black little spot when I look at it straight in front with a, say, red, green or blue background behind it. I mean that there isn't any idea to run the pixel fixer if I know that they are dead.

You, know, I think I just fixed it :P
I read a lot on different sites just what you wrote here, but I wanted to make sure I had stuck and not dead pixels!
Anyway, I ran the little movie file which flashed colors and then I just rubbed the spot with my finger... they both disappeared! Took less than 10 seconds! Using both the methods at the same time did the trick for me (in the short time I tried it anyway!)
Would be pretty cool if my "dead" pixel on my external monitor disappeared also... Hehe, I've lived with that one over a year
Thanks for the fast reply!

Stuck Pixels after Installing iPhone 2.0.1 Update

Has anyone else noticed any new stuck pixels after installing the iPhone 2.0.1 update?
As you can see in the image linked to below, my 8GB iPhone 3G began displaying a stuck pixel in the upper-left immediately after installing the 2.0.1 update. At first, I figured that this was an average stuck pixel that coincidentally appeared immediately after applying the 2.0.1 update. However, after further examination, I don’t think that this is a normal stuck pixel.
http://skitch.com/macmanx/1igt/stuck-pixel
A few hours later, my mother updated her 8GB 1st gen iPhone, and as you can see in the image linked to below, she now has a vertical line of stuck pixels in the same region as mine. Since her stuck pixels also appeared immediately after installing the 2.0.1 update, I’m beginning to think that my stuck pixel may not be an isolated issue.
http://skitch.com/macmanx/1i88/stuck-pixels
I have tried to restore both iPhones, adjust the brightness, apply light pressure to the stuck pixels, and run the Knox Pixel Fix for iPhone. Neither method worked. To further complicate the issue, the stuck pixels appear to flicker when viewed through the LCD screen of my digital camera.
Stuck pixels are (as the name implies) stuck, they do not flicker. This, added to the fact that the issue occurred immediately after applying the 2.0.1 update, leads me to believe that this may actually be a software issue, possibly involving a conflict between the display drivers in the update and the display hardware shipped with certain iPhones.
If you have also noticed new stuck pixels after installing the 2.0.1 update, I'd love to hear that I'm not the only one seeing this. And, if you have somehow managed to resolve the issue, I'd love to know how you did it.

As already pointed out, "stuck pixels" are hardware related. They will be evident all the time, regardless of the particular screen being viewed. If they show only on particular screens, it isn't a dead pixel, but a software/ driver issue. I see a horizontal line in my Unlock Screen that I didn't notice before 2.0.1, but I'm not sure I really looked for it before. However, I don't see it in other screens with a black background such as the Home Screen, indicating it has something to do with the Unlock Screen image, and not the LCD pixels.

Dark spots behind display..

Its been 4 months since I purchased my MBP and it has been working quite well since.
But recently it's displaying two odd dark blue spots close to the center of the screen.
At first I asumed that they were stuck pixels but then I realized that they do not interfere with the colors on the display, but actually they just seem like stains in the backround.Also they are most visible when I use bright colors, and they are not visible when the display is off.
All my attempts to correct this problem have not worked, I tried cleaning the screen with an LCD cleaner kit and I even tried pressing against them with my finger but there is no change.
I would be very thankful if someone could shed some light on this problem.

Have you called Apple Care about this issue? I would sugget you do because LCD spots issues are covered by the warranty and are replaceable. Take a look at this...

I've seen spots issues and yours seems to be one.. Goodluck!

Dust and a hair behind my screen......

Hi I was wondering if anyone can tell me how to get a hair out from behind my screen on my macbook. There is a small hair probably off my dog(!) central to the bottom edge of the screen. I also have small dust particles about the place too. How are they getting in there and how can I get them out? The dust spots are not dead pixels as you can see they are long and wiggly and very annoying!
Thanks.....

This problem happens more with laptops, just google for "dust behind laptop screen". Normally, a laptop screen is sealed off at the sides by rubber, so dust cannot get in. Somehow (perhaps due to age?), the sealing wasn't 100% perfect on your Macbook. Sadly, there's not much you can do about it, unless you're willing to open up the laptop. It's a major procedure for which iFixit has a manual:
http://www.ifixit.com/Guide/Repair/Installing-MacBook-Core-Duo-LCD-Panel/311/13# s1213
But then again, that only might make things worse, or you might not be able to reach the spot in question.

I have a stuck pixel

I have researched how to get rid of a stuck pixel and tried different things but nothing seems to have worked has anybody else got this problem or had this problem and have a solution? Thanks.

On my original iPhone 4 I had 5 stuck pixels, all showing green.
After booking an appointment at the Apple Genius Bar (Regent Street) I was hit by a car on the way so I arrived three minutes late to get a replacement before going to hospital, and was told I now wouldn't be served due to being 3 minutes late (I frequently wait 45 minutes or more beyond my appointment time to be served, even though I always arrive early).
I went to my local o2 store where they had just received a batch of 32GBs in and got a replacement hand set from them instead... and now I see this replacement handset has stuck pixels too! One very obvious in the middle of the screen and 2/3 more around the edges that for some reason look smaller (I'm not sure if the centre one is 2 pixels side by side or what).
Is it worth going back to O2 again? Or is this something that just ***** on the iPhone 4 retina display and I have to put up with it?
Not too happy with Apple right now! (For the first time ever, though)
