Screen has a bad pixel

How long does it take to get your phone back if you send it in for repairs or will they swap it out for a new one?

They'll likely just replace your device. That's what they did for my first one when it had a bad pixel.... and my second one when it froze during voice input during navigation or texting... and my third one when it wouldn't scroll all the way down to the end of my photo album... and my fourth one because it was an unacceptable replacement (case not aligned and nicks on the edges). BTW the 3rd and 4th ones were "factery certified like new"... yeah right.
If you call them on the phone they'll just send you a "new" one with a return label for yours.
I gotta tell you, I really like the functionality of this phone when it functions correctly but this is getting ridiculous. Maybe I'll start a new thread with my gripes to see if I'm in this boat alone.

Screen has black/dead pixels and line across screen.

My iphone is still under its one year warranty. I can not recall any drops or it ever being handled roughly, however I have a black/gray blob of dead pixels in the left corner and my screen has a shiny line that looks like a crack of the LCD, however the glass screen is not cracked in any way that I can tell. I think the dead pixels are spreading as well. Has this happened to anyone else? Does anyone know if this is under warranty? I live over an hour and a half from the nearest apple store so I really don't want to take a special trip to see a genius only to find out that I will have to pay $200 to get this fixed. Any help/advice would be greatly appreciated!

If it is still under warranty, they should replace the screen without charging you. The same thing happened to me a few months ago and they replaced it for free. You might have to make the long trip to the store but they shouldn't charge you and it will take about 30 minutes. Call to make an appointment first if you plan to go to the apple store.

Bad pixel or?

I have noticed a very tiny pixel on the bottom left of my screen that almost looks like a pixel-sized 'light'. It is very distinct and appears white. Is this some kind of sensor behind the screen or a bad pixel?

*"My laptop is about 2 months old - will Apple take it back and give me a new one?"*
No. 1 bad pixel out of the millions on the display is considered acceptable by today's industry standards.
If it's stuck you can try rubbing it out.

My screen has a red mark on it. Are the pixels damaged

My iPad mini has a red mark on the screen. Are the pixels damaged ?

No one here can answer that question. Take it in for diagnosis by a technician.

My iPhone has been badly damaged and I cannot get the screen to work. I want to do a backup to transfer to my new phone but the backup will not work because the phone is locked. Can I input my lock code to the phone via the computer to allow a backup?

My iMac 27inch 5k screen has a huge line of dead pixels. I bought it today itself!!!

I Just bought my iMac 27inch 5k and after Unboxing it, came to realize that the screen has flickering and dead pixels all over the left side.
is this a hardware or sodrware issue and can I repalce it with a new one since my warrantee is a day old?!

If you bought it directly from Apple, you have a 14 day return or exchange window. Take advantage of it.

How to add bad pixels to a DNG made from a CFA sensor raw data ?

Hello all, I'm trying to build a proper DNG file from the raw CFA image acquired directly form an industrial camera.
As usually there are a number of bad pixels around and I would like to mark them in the DNG so they can be correctly interpolated when the image is processed.
In the latest DNG SDK (1.4) I've only found this rather thin references:
"Defective Pixels
There are two ways to deal with defective pixels in DNG.
The first is to map out (interpolate over) the defective pixels before storing the raw data in DNG.
The second is to include a bad pixel fixing opcode in the OpcodeList1 tag."
OK, as each program/customer/etc. seem to have its own ( best ) algorithm to interpolate the bad pixels then OpcodeList1 it is.
But then I've got this: FixBadPixelsConstant and I'm not clear about its usage, especially BayerPhase, is the same BayerPhase that is specified as a global property of the CFA or it is something separate and what ?
Also is there some "industry standard" value for the Constant that will make more likely the established programs to process correctly the image ?
And this Constant value is unique per DNG or can it be more ot them added, i.e. to somehow characterize the "badness" of the pixel, like reduced sensitivity, stuck at 0/max, etc ?
In the end if somebody can share an one-liner on how to add programatically this tag using the SDK I'll be very grateful.
Sorry for my newebie questions and many thanks for your help.

Hello Dear
Look FB60 screen has two parts :
The one in which you enter information related to vendor is Header Level, in this case you already assign Personnel No. in Vendor Master so no field is required as Personnel no. will be picked up from Vendor Master level.
The Other is line item level is bottom half part, if you want to assign personnel no. at Expense G/L level then if you scroll right you will find a field for Personnel no. If you can't see the field check your setting at OBVV for the field status group you assign to particular Expense G/L.
Hope you Understood
Cheers

My New T500's LCD(LED) Has a Light Pixel

I bought a T500 in lenovo's website and received it today. Without further examination, I found a obvious light pixel in the LCD. I'm very sad about this.I know lenovo promised that customer could chage their LCD when they found 3 or more defective pixels whenever within the warranty period. But after all, this is a brand new computer, it make me so unhappy. May I change another machine?

You can always ask support. I prefer to buy my ThinkPads via phone from a Lenovo sales person. That way I have a (admittedly transient) personal connection, and someone to ask (beg) to take a machine back. I also find that a live sales person usually has access to additional discounts that don't show up on the website.
Otherwise, you could go with the no-fault return, take the 15% hit, and see if the next one is perfect.
ajkula66 is correct that Lenovo's bad pixel policy is better than most. That said, out of 10 recent laptop purchases, 7 of which were ThinkPads, I have only one with a bad pixel. There's one stuck on in my Acer Aspire One screen, but for $250, I don't think I care.
I do feel your pain. If there was a bad pixel on my T400, i would probably pick at it until I had a hole in the screen...

Bad Pixel in Camera

Just got my K1 and have been going through the preloaded apps. All was fine until I opened the camera. There appears to be a bad pixel in the camera, near the center of the screen. It is there regardless of whether it is set to still or video. It appears in any picture or video taken.
What is the repair process here? Will the whole system just get replaced? Can the camera just be replaced?
Solved!
Go to Solution.

Chooks,
Why not bring it in to work on Monday and well have a look at it? If the camera has to be replaced we can set up service, but it will be good to see what you are talking about before it is repaired.

Bad pixels in the camera sensor

I've got an iPhone 4S, 64GB (Verizon) and noticed a few bad pixels during video playback on our 42" TV (played back via the HDMI adapter). It's something that most people would not notice, including my wife as she watched the video with me, but I'm a long time video/photo enthusiast and imperfections like that stand out to me like a pimple on an otherwise perfect looking face.
After several test videos and even photos, I am able to reproduce this pixel anomaly each and every time. There are 3 pixels, just slightly to the left of the center, that show up incorrectly in kind of an obtuse triangular formation. Two of them favor white, the third is dark. It's not something that is noticeable on the iPhone 4S screen because not all of the pixels are shown, but on a monitor that can render *all* pixels of 1080 HD video playback they show up.
I'm certain it's not dust as I've inspected and gently cleaned the camera window, not to mention even a small spec of dust would not show up as a single pixel (or in this case, what appears to be two pixels right on top of each other for each of the problem pixels). The anomaly shows up when lighter colors/gradients are present in that region of the screen. Darker colors do not reveal the bad pixels. Just to be clear - it's NOT a screen display issue - the pixels are noticeable on our 42" TV during playback, and also on my Mac monitor and iPad screen (ONLY when zoomed in viewing on my iPad, which is possible during playback of video using the stock photo app). The bad pixels jump around a bit because of the digital image stabilization (that should make sense to the more hard core video enthusiasts), which further supports it is a capture issue, not a video coding problem or anything like that. The issue is either with the image sensor itself, or the hardware's processing there of.
My question - has anyone else observed similar behavior? If so, is there something you're aware that can be done to correct it? This is my second iPhone 4S, the first being a perfectly-functioning 32 GB model (which did not have this issue) that I returned in favor of a 64 GB model because I was burning through space too quickly.
I'm probably going to have to go back and try to explain this to the good folks at the local Apple Store, and try to get a replacement unit, but I'm not looking forward to having to show video samples and point out three teeny little dots that most people won't even notice, but drive me crazy (especially after dropping $400 plus tax and a two-year commitment). A huge selling point of my iPhone 4S was of course, its superior photo and video capabilities. I understand they're not pro quality, but there shouldn't be any consistent pixel issues like this going on.
Sorry for the long post, but I'd appreciate some feedback, suggestions, input. Thanks.

No worries. I agree - text-only communication can be a rather clunky experience in trying to convey complex issues without any visual or (2-way live) verbal means. I was a bit worried about being too wordy in an already wordy post and feared that it might just be ignored if it was too long. Again - I appreciate your chiming in. You seem very knowledgable in digital photography, which is exactly what I was hoping to find.
Given that my description of "bad pixels" is a bit sloppy for what is really going on, I think you understand what I mean in my usage of those words.
To answer your question, the offending pixels, or very, very small little dots of imperfections, are present in both video playback and in still photos. After shooting several test videos against neutral and textured backgrounds to see what kind of results I'd get in the appearance of the bad pixels, I also took several stills in "burst mode" using an app called "Camera-" against a wood grain background, as the woodgrain background offered the most visible and consistent view of the blemishes. In motion video, the dots (bad pixels) are pretty easy to see on a large display, or when zoomed in during playback on my iPad 2's screen. In stills, it was kind of tricky to identify them, because without the persistent motion of the background, the bad pixels almost blended in as random image noise. I was however, able to identity with certainty the same bad pixels in most of the stills. Additionally, at the higher resolution of the stills, the offending pixels almost don't even need masking or removal with photo editing software. Like I said - without the constant visible background motion to make them stand out as irregularities, or the ability to do a frame-by-frame analysis (which I can do easier with the video file using an app called VideoPix), the bad pixels are more difficult to identify.
The importance in identifying the bad pixels in stills, even though they are practically not noticeable, is that it can now be determined that the bad pixels are not the result of some kind of video coding glitch, but rather present in the hardware of the device itself - either as a defective image sensor, or defective hardware that translates the data from the image sensor into the pixels utilized by the software for photos and video.
As part of the tests I ran, I captured video with an app called KingCamera, and it, too, produced the same results. KingCamera also has an option for "locking" of the auto white balance and brightness, loosely similar to setting those manually on a higher-end, dedicated camera. Even locking the white balance and brightness, the pad pixels were present, so the potential for the issue being caused by an anomaly in the software's auto-settings management were put to rest.
In regard to being able to correct the bad pixels in stills - yep, easily done. BUT, I shouldn't need to. In terms of correcting them during video playback, that *is* actually something I could probably work out a method of doing. I used to dable in production videos that involved complex imaging filters, multiple composite video layers, and automated ways of identifying specific colors, contrast points, and patterns within images/video streams and altering them (such as cleaning up sloppy image mattes or locking in on visual patterns for the application of various video effects). Again, this is something I *shouldn't* need to do.
The still photo and video capabilities on the iPhone 4S are outstanding, in contrast to what other similar existing devices offer (arguably better than or almost as good as the best competitor offerings, depending), but the quality is not DSLR, and like I said - I'm not expecting it to be. I do expect however, and I don't think it is unreasonable to, image rendering without persistent "bad pixels" showing - even if I am only in the 1% of people who are likely to notice such image defects. They are, in fact, defects, and not "normal operation for a device of this caliber".
I was hoping there might be some trick to correct them, but I kind of figured there would not be. It seemed smart to at least reach out and see what other people may know that I might be missing. Again, I regret terribly my poor decision to return my perfectly-functioning 32 GB iPhone 4s for the 64 GB model. Knowing a little about the very intricate technologies that make these things seem "magical", I understand that there are dozens or even hundreds of very complex little components that are mostly stamped out on an assembly line of robot fabrication means, then assembled, at least in part, by humans in a factory who are required to pump out x number of these things in short periods of time. I worried about the possibility of trading in my perfectly functional device for something that may be just a tad less perfect - just because of the odds. My bad for not following my natural instincts on this one. I just didn't want to have to constantly be managing space on my device. I failed to think through my initial choice of the 32 GB model in regard to my trigger-happy photo/video nature. The cumulative files are much larger on this device than I was initially expecting (because I was just too excited to get my hands on one on October 14 and failed to do enough research and calculations). Days into owning my 32 GB 4S, I was already spending time, almost daily, re-rendering videos at 720 and 580 through iMovie, being somewhat irritated about having to replace the original videos with reduced resolution versions just to keep the videos live on my iPhone (sometimes archiving the originals on my Mac first). Anyway - enough of my rambling.
Thank you again for your input, pogster. If you have any other ideas, please share. I'm pretty sure I know what I have to do to feel happy with my investment, though. I'm just not looking forward to complaining about 3 bad pixels to a Genius Bar employee who's probably going to look at me like I'm one of those "never happy with..." people. Three bad pixels that I won't even be able to show ON the actual iPhone itself, but rather bring my iPad 2 and show zoomed-in playback of the video footage.

I am at Ramstein AB Germany. My iphone screen was smashed badly on the flight to Germany this morning. WHEN I access apple support for this subject it gives me 3 options call now, call me now or call me later. As I am in Germany with no coverage and no working phone none of those options will work. Can you get this e-mail to someone who can help. My iphone serial # is C38xxxxxx. 1) I need to know where and how I can get a replacement somewhere nearby in Germany 2) If 1 is not an option I need to set up an appt to get a to get a new iphone at an apple store in Atlanta GA in the evening of 11 July.
Thank you very much, Phil Edelen

Thanks, my wife is the one serving I am retired and trying to follow her as much as I can.
I will schedule an appt for my next time stateside. I have spent too much time on many Apple web sites trying to get an e-mail to communicate with anyone at Apple to no avail, only phone numbers. I guess if you are overseas with no international access you are out of luck communicating with them. I did find one e-mail address but the reply was computer generated and provided useless links.
If anyone has any e-mail address for anyone at Apple I would appreciate it.
Thanks again,
Phil

Screen has lines running through it, is it worth replacing screen?

Screen has lines funning through it, is it worth replacing screen on 2009 iMac?

What do you mean by lines running through it? There have been users with vertical lines, sometimes blue, or yellow, or pink, or combinations. Those have all turned out to be a bad graphics unit chip that the Apple store techs were able to remove and replace without replacing the entire logic board.
Take it to an Apple store genius bar and have the techs test and advise on how to resolve this.

IMac 17' screen - has lines and is freezing help!

I have a IMac 17' - My screen has lines across it and sometimes a triangle- If for some reason I'm able to get it to work past the users choice screen, it freezes within mins. Does anyone know how to fix or what the issue might be?

It's probably a bad video card or bad caps (the little soda cans) which are either swollen or leaking. If your machine isn't an iSight, take the back off and inspect the caps.

DV2000 has a bad hdd that won't power up

This DV2000 i'm working on has a bad hdd that won't power up & used a usb device to clarify the issue.
Shouldn't the system bootup to bio's even though the hdd is gone?
Worked on alot of desktops & I know they should boot to bio's so you can set the hdd to auto.
This thing now won't even bootup to the bio's, just a black screen with all light's lit up on keyboard & on front.
It beeps 2 short beeps (very low beeps). No loud annoying beeps like i've read on here & the support site.
I'm pretty sure it's not a overheating gpu issue.
Hooked it up to an external monitor & stll won't show a screen as long as I entered the right keys.
Thank's for any comments you might have.

First thing, see if it will boot into the Recovery Partition: Hold down Command R at restart.
If it boots up there, then it's likely that the hard drive has failed, or simply doesn't have a working system.
If it doesn't boot up there, then it's likely to be some other part of the hardware.
If it is the hard drive, then this can be replaced. You can find videos showing you how to do this on sites like ifixit.com.
Then you can just restore all your data from your backup. You do have a backup, right?
