Ring of dark pixels

For the past couple of months I've noticed a ring of dark pixels on my screen.
http://img141.imageshack.us/img141/9826/dsc007521mh9.jpg
I'm not sure if this is a problem with the actual display or if the back of the glass is just dirty.
Anyone have any idea what this might be? I plan on eventually bringing this in to a genius bar, however I know it will be a pain in the neck not having my computer for a week or so. Plus wiping my data in case I get a refurb or something is also a hassle.

Richard,
Welcome to Apple Discussions.
As has been stated you might have a hardware problem however you can do a SMC and PRAM reset. This is pretty easy to do, here the instructions:
1. Turn off your iMac and unplug everything from it for 30 seconds.
2. Plug in the power cord, keyboard and mouse only.
3. Press the power button and immediately hold down the Option, Command, P & R keys until you hear the second gong then release the keys. Your machine will start up normally, then check for the issues you are having.
If it does not fix the issue contact Apple, remember you have 90 days of free telephone support from the original date of purchase and 1 year of warranty. If you haven't already I would recommend you purchase AppleCare while you still can.
Regards,
Roger

Dark Pixel Line In Captured Image

Hello,
I am trying to use a high speed machine vision camera (AVT guppy PRO F503C) to analyze touch screen LCD user interface modules for pixel defects, foreign particles, scratches, etc... However, this process is hampered by a dark line of pixels which tracks down the screen continously during image acquistion (both grab and continous grab). I have had a little success adjusting the camera shutter value to minimize the visibility of this line, however, this has proved to be relatively inconsistent as the shutter value seems to differ from unit to unit. I am wondering if anyone has ever run into this issue and if there is any corrective action to eliminate or minimize the effects of this line (lighting, camera settings, etc..). Here is an image:

Go to Solution.

Here is a workaround. No charge. This time
I'm assuming the line always shows up in a different position vertically in the image. If this is not the case, you may need to change the framerate so that the line moves around. The VI I have attachec take in images from your camera until the "# of Images to Consider" value is met. While it is collecting the images, it builds a sigle array of the max pixel values that came before. The resulting image will not have the line. You will need to play with the # value to figure out what works for your application.

Dead dark pixel in Ideapad s520p 5941135

I just bought my Ideapad s520p 59411351 4 days ago from a store and when I came home realised it has a dead pixel on the screen, it appears as a dark dot on the bottom right. I am a designer and just can't live with this !!
So I went to the store the other day and showed them the defect. The manager confirmed the defect and told me that they have no replacement policy !!! So he suggested me to call Lenovo support,
So I called Lenovo support, they sent an engineer who poked around the pixel and told me that I will get a reply from Lenovo in a day . today I got the reply that LENOVO DOESNT REPLACES DEFECTIVE LCDs WITH 1 DEAD PIXEL.
what do I do now ?? you pay full money for a brand new machine and get a defective piece and still don't get a replacemnet !!

hi goldensalamande.
warranty conditions may change by country but as i know if you don't have dead pixels more than 4, warranty won't replace it.
still, to make sure, you can call lenovo support line for further informations.
hope this helps.

Particles "white pixel" Bug

I discovered that when using Particle Playground, with the particle type set to faded sphere, and the color of the particle set in the purple/violet hue range, that a ring of white pixels dust appears around the circumference of each particle. If I change the particle color to green or orange or something outside the violet range, the artifact vanishes.
This is in CS3, and it appears during both preview and render to RAM.

The pure white pixels are abruptly-gone when the hue is rotated away from the violet range, so I don't think it's an HDR issue. Also, I noticed on the larger particles passing closer to the 'camera' that the white pixels form a complete circle, which gets cropped off as the 'bubble' (what the white pixel outline looks like) passes about 1/4 of the preview window width to the right. The left 1/4 of the window shows this artifact--the rest does not. I also confirmed that this does not show up on rendered images.

Quickest way to find the darkest pixel in an image

I was wondering what the absolute fastest way to grab the darkest pixel(grayscale) in a picture. Or if anyone could give me any ideas on how one would go about making a fast dark pixel finder.

Is the image Greyscale or RGB?
Either way - you can access the data by getting the Raster
Raster r = image.getData()
Lookup the methods on Raster - you can access the data as one array.
If the image is RGB - you will have to convert it to a Greyscale value (you let the JVM do it by creating a new Greyscale image and drawing to it, or doing it yourself by access each one and performing the math)...
Lemme know...

IMac screen gains dead pixels from Mac Store visit???

My 3.4gHz i7 2011 27" iMac died, so I brought it into "The Mac Store" here in Portland (an authorized Apple reseller and repair facility). According to the work order, they changed out the logic board and the video card under warranty. When I picked it up last week, I noticed there was now a spot of 4-8 stuck dark pixels (all next to eachother in one big splotch) on the LCD that wasn't there when I dropped it off. I opened it up to put my hard drive back in and I saw that the SMT connector on the top of the video card (ambient light sensor?) was damaged, the plastic was broken and the plug was hanging on by gravity, not plastic tabs. So it still works, but the cable could pop off on it's own.
My assessment is careless work. The LCD was either swapped for a different unit, or damaged by the repair techs. Is it possible that a LCD can be damaged in a way that it receives a spot of dead pixels? AFAIK thats a sign of bad transistors and more of a manufacturing defect, which leads me to suspect the LCD was swapped out. The pixels are next to eachother both vertically and horizontally, so I'd doubt it's a video card issue.
The way the video card is damaged shows me they were careless during installation of the new card, and either didn't notice it (doubtful) or figured I'd never notice so they left it. Just speculation on my part, but as someone who does IT consulting for a living myself, it seems really sloppy either way.
I emailed the customer service address twice (in response to my work ticket) and the local store manager once, but have not received a reply or acknowledgement. I had to reschedule a second appointment and go in on my own. When I did the, the guy who received my iMac at the service desk said while it is not his call, he doubts they will fix it as "Apple has a policy regarding a certain number of allowable dead pixels", which completely neglects the fact that my LCD was perfect when I brought in the machine for unrelated service. He also said that the fact that I noticed the bad video card connector shows I was opening up the computer to reach non user servicable parts and therefore they probably wouldn't cover that. Which is ridiculous to me for a couple reasons, first, the Apple Warranty terms of service say nothing about voiding warranty for changing out the hard drive, second, it's illegal to void a warranty if I didn't damage the unit while servicing a user servicable part, and third, that gives them a self defining ability to damage anything inside my computer and then if I notice it they use the fact that I noticed it as a way to get out of fixing it. Kind of a catch-22 if you ask me.
So I'll be posting my follow ups to what happens here, but in the meantime, my questions -
- Can a LCD gain bad pixels from careless handling? Can a splotch of bad pixels be related to a bad video card?
- Has anyone had service like this from Mac Store or Apple before? I paid a lot of cash for this system and this is pretty frustrating.
regards,
Rob

Follow up post - I brought the system back, they were really nice, the escalated it, I got it back in 2 days, they must have had to overnight some stuff for that, and probably ate the costs themselves. The replacement LCD is perfect, the backlight board was swapped, everything is good, and they were nice to deal with the whole time.
I should have given them a chance before posting here. They went out of their way to treat me well, and that is appreciated. Please ignore the frustrated tone from my first post, it was just grumpiness on my part. Crap happens, customer service is how that crap is dealt with, and they did a very good job.

Imported pentax RAW files goes dark

Hi,
I bought Aperture earlier today and have had nothing but problems importing my images (RAW images that is, jpg files are fine). In the preview where you choose which images to import they look ok (as shot/as in photoshop) but after import they go dark before my eyes (really dark, mb two full stops darker). I tried searching for a solution and found similar problems but no solutions to my specific problem.
Setup:
MBP 4,1
OSX 10.6.7
Aperture 3.1.2
Pentax k100d super
After I installed Aperture even finder shows the raw files incorrectly (i tried opening one of the files in a lightroom trial and thats seems to work). Thanks in advance, i really want to like this program...

Hi,
I have the same camera, and exactly the same problem. Could you solve this issue ?
About images of Pentax cameras looking dark in Aperture, many people mention "if Highlight Correction is enabled, the image is shot at -1 EV exposure compensation, and then everything but the highlights is pushed up in the camera when it makes the JPEG version" -- and thus the solution seems to be to disable this highlight correction. But to me it seems that there is no highlight correction in the k100d super...
Aperture 3 actually clips the histogram (dark pixels turn completely black) with respect to the same PEF file read with the Pentax Photo Lab app or the Gimp. The "Raw Fine Tuning" adjustements do not solve this.

Weird pixel behavior @ the bottom of the screen

A black line then a transparent line, building a shadow at the bottom of the screen. I researched for that and maybe i thought that it could be dead pixels, but i think it's not, because i guess dead pixels are red, green or blue.
have you guys seen this before?
PS i didn't restore it yet. Would it fix it?

Imported TIF is pixellated

I wanted to make a menu with the background3.tif graphic (which is used in the Wedding Band DVDSP template) as a 16:9. When you simply change that menu to 16:9, the ring becomes oval. So I brought the tif into photoshop, duplicated the layer, moved it over, and smudged the overlapped line to make a 16:9 photo. I then flattened the layers, saved as TIF and brought it back into DVDSP as a background. The ring is now pixelated. I tried doing this as a png and got the same results.
So I tried creating a blank file in Photoshop at DV Anamorphic settings and copying the TIF into that file. Now I can see in Photoshop that the ring is pixelated. I'm not quite sure why or what settings I need to change to get my smooth ring back. Any suggestions?

Are you talking about field reversal? Media 100 files are upper field first, are they not? Perhaps you just need to adust the item properties.

Sudden dead pixel?

I recently replaced the hard drive in my late 2009 iMac, and after carefully reassembling the components, I've got what appears to be a dead pixel near the middle of my screen. (I really hope it's just dust.)
Assuming the worst and that it is a dead pixel, what would've caused it? I was exceptionally careful when working inside the iMac, only lifting out the display the bare minimum distance to access the hard drive, and the only display cable I unplugged during the process was the vertical sync ribbon cable.
Any thoughts?

It's really hard to tell, because if it's a dead pixel (or "dark pixel anomaly"), then it's a single one. As such, it's really difficult to see, even when I've looked at the thing close up. However, I'm beginning to lean towards dead pixel, as I can't see any colors through it at all; tried a variety of different backgrounds.
I'll open the display up again and clean it out again just to make sure, but if it's a dead pixel, there is no fix for that short of replacing the entire display, correct?

What does a dead pixel even Look like ?

I posted a thread 24 hours ago that ended up w/ a missing section, then 2 replies to finish.... a real mess that went deservedly unanswered.
I'm sure I can do better :
Suddenly I've got 2 "bits of dust" towards the lower right corner of my 24" display. They're different sizes ( the smaller close to a pin-head ) and the slightly larger one is a much darker shade of grey. They're also roughly-edged...misshapen.
They look like pieces of grit , is it even possible for a foreign particle to "ride in on a CD" and end up visible within the display ?
I'm sure that's doubtful, but I don't know much beyond what they "look like"
I've tried the Pixel-Fixer widget, but have seen no effect.
I'd just like to hear what else others may have had, the better to determine what these interlopers actually are !
thanks, Dave

The LCD is a sealed unit before it's placed in the computer so no it's not possible for foreign particles to "ride in on a CD". It may be possible for dust to get under the "glass" that covers the LCD, but again, not from a CD.
I'm sure that's doubtful, but I don't know much beyond what they "look like"
Apple has a decent article on pixel anomalies. In order to keep LCD costs down, a certain number of pixel anomalies are considered "acceptable" by most manufacturers. Some resellers offer a dead pixel warranty for an extra cost. They lose money with individual LCDs that are returned with pixel anomalies that are considered "acceptable" (the manufacturer would bill them for repair or replacement) and usually sell them at a reduced cost. In the long run, though, most LCDs don't have pixel anomalies so the more dead pixel warranties they sell, the more profit they make.
I've tried the Pixel-Fixer widget, but have seen no effect.
Software like the Pixel-Fixer widget are often just temporary solutions. Stuck pixels usually indicate a hardware issue with the LCD matrix and the only guaranteed way to make sure they're gone is to replace the display.
This picture mistakenly refers to a "bright" pixel as "dead". When the pixel is stuck in an open position (allowing light to pass through) it's a "bright" (sub-)pixel. When it's stuck in a closed position (blocking light from passing through) it's called a "dark" or "dead" pixel.
This picture shows a dead (or "dark") pixel.
Hopefully that clears some of your questions.

Policy and best way to get dead pixels fixed.

I have an iPhone 4 and I have 1 or 2 dead pixels surrounded by about 20 dark pixels. I was wondering if the default warranty would cover this or if I'm stuck with it. Overall the dead pixel isn't that noticeable but the dark cloud around it is really annoying. Thanks for any help you cann offer.

Compilation of Lenovo X120e issues and solutions

Just thought a compilation of issues may be beneficial for folks who own an X120e.
Screen adjusts brightness automatically without user input depending on content on screen:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/X100e-screen-brightness-increasing-by-itself/td...
This is caused by Vari-Bright being enabled in the Catalyst Control Center. With this option enabled, the screen will automatically adjust its brightness depending on what is shown on the screen. The display brightness is increased when the screen is predominantly white while the display brightness is decreased when the screen is predominantly dark. An easiest way to see this effect happening is to have two tabs opened in a web browser window. Set one tab to display a website that is mainly filled with white pixels (such as this Lenovo Forum) and another tab to display a website that is mainly filled with dark pixels (such as http://www.krijtenberg.nl/ ). Switch between the two, pausing a few seconds in each tab.
Solution:
Open the Catalyst Control Center and select the PowerPlay option in the Power section. Uncheck the Vari-Bright option (or adjust the slider) and click Apply. Verify that the automatic adjustment is no longer occuring by doing the two tab experiment described above.
Function keys for brightness control not working after waking from sleep / hibernation in some instances:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-Funtion-keys-for-brightness-not-working/t...
For my X120e, whenever I have it sleeping or hibernating and change the power source (such as initiating sleep when on power and then waking it up while on battery, or vice versa), the function keys for brightness controls do not work.
Solution:
Restarting the machine will bring back functionality of the brightness control keys...
A way to prevent this from happening in the first place is to wake the X120e in the same power state that the X120e was put to sleep in (wake up from power adapter if slept while connected to power adapter, or wake up from battery if slept while on battery).
All we can do now is wait for Lenovo to come up with a fix on their side of things.
AMD SATA Controller and TRIM for SSD:
The AMD SATA Controller provided by Lenovo does not support passing of TRIM command according to http://www.hardwarecanucks.com/forum/450343-post35.html for SSDs. The Lenovo provided AMD SATA Controller is 1.2.1.197, before the official TRIM support in 1.2.1.263. If you're using a HDD, this is of no concern.
Solution:
In order to have support for passing of TRIM command, one has to update the AMD SATA Controller to any version above 1.2.1.263 ( http://sites.amd.com/us/game/downloads/Pages/integrated_win7-64.aspx#3 for Windows 7 64-bit, for example) or uninstall the AMD SATA Controller to revert back to Microsoft's Standard AHCI 1.0 Serial ATA Controller.
Disclaimer: Since the AMD SATA Controller driver linked is not from Lenovo themselves, I'm sure they won't provide any support if something is to occur so try at your own risk.
As HP79 mentions below, at least according to the update notes, TRIM implementation is implemented for Hudson chipsets as of 1.2.001.263.
Audio Stutter / Slurring occuring during playback of video/audio:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-Stuttering-Audio/td-p/389023
This issue can be reproduced (at least on my X120e) by waking the X120e after putting it to sleep. The symptom is the audio repeating a sound over a span of a second or two during playback and is quite noticable.
Solution:
uEFI Bios version 1.11 seems to deal with the audio stuttering issue. So far, results lead to positive outcomes.
Old Solution:
PWMTR64V.DLL that is loaded at Startup seems to be causing this issue. Disabling it from launching when starting up seems to cure the Audio Stutter (even after waking up from sleep which was seen to be a pretty reliable way to get the issue to repro). Start Menu > Launch MSCONFIG from the Search Bar > Select Startup Tab from the System Configuration window > Uncheck Thinkpad Power Manager > Restart.
This does not seem to turn off the power manager application itself so settings in Power Manager can be saved and it seems to still be in effect. However, opening up Power Manager from the notification / taskbar can cause audio stuttering and mouse movement slowdown while it is launching and/or when applying settings. This is only temporary and is gone when Power Manager is closed. (Thanks kns7977 for the find)
Pending to see if those who uninstalled Power Manager are able to turn off the offending startup .dll.
Mouse seems to stutter or stay in place for a moment when moving:
This seems to be caused by the same issue causing the Audio Stutter / Slurring. At least at this time, the cause of the issue and solution seems to be the same.
Emulating Middle Mouse Button with Trackpoint:
One can set up the middle button between the left and right click button for the TrackPoint to act like pressing a middle mouse button on a standard mouse by changing the scrolling type to Smooth instead of the default Standard.
Control Panel > Hardware & Sound > Mouse > UltraNav Tab > Setting for TrackPoint > Setting for Choose Scrolling or Magnifying Glass Function > Smooth.
Trackpad's two finger gesture being hit or miss:
The trackpad's two finger scrolling is very hit and miss.
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/X120e-Touchpad-issues/td-p/393751
Solution: Turning off Gesture Filtering may alleviate the problem. As mentioned in http://forum.notebookreview.com/lenovo-ibm/561751-x120e-owners-thread-24.html#post7323293, it seems that the Gesture Filtering is counteracting any sort of two finger input.
Get to Mouse Properties by Fn + F8, select Manage Settings. At Mouse Properties, select the UltraNav tab > Settings for TouchPad. Expand the Smart Check Settings, highlight Gesture Filtering, and uncheck the Enable Gesture Filtering box and Apply.
Screen flickers lines:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-Flickering/td-p/389523
Had this issue occur on me once, but never seen it happen again. Unsure what caused or cured it.
Solution:
If the flickering is occuring, a restart is all that is needed to alleviate the problem. Haven't tested if hibernation fixes it, but neither sleep nor turning off the screen with the Power Manager dealt with the flickering.
3-Cell Battery mentioned as a 40Wh in the Order Page of Lenovo X120e when it is actually rated as 32Wh according to Power Manager:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/X120e-3-cell-40Wh-battery-reported-as-32Wh-by-P...
Yeah...
Solution:
Accept that it's a 32Wh you will get when selecting 3-Cell or go for the 6-Cell if you want more than 32Wh.
2x2 ABGN Driver from Lenovo triggering Error Code 10:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/X120e-ABGN-Driver-issue-in-Windows-7-Pro-x64/td...
The Wireless driver from Lenovo's site seems to not work with the 2x2 ABGN wireless when installed on a fresh copy of Windows 7 x64.
Solution:
Not really quite a solution, but one can bypass this by either installing the 32-bit Windows 7 and installing the 32-bit driver, or using the factory recovery disc to install 64 bit windows 7 to have it install drivers that work for x64 windows 7.
X120e bluescreens after installing LAN Realtek 7.26.902.2010 drivers from Lenovo's Driver download site.

The drivers doesn't seem to work and it causes a bluescreen on fresh installed Windows 7 x64.
Solution:
As Clicq suggests, Realtek's own drivers from http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&DownTy... seems to deal with the issue.
Screen quality on the X120e:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-poor-LCD-quality-viewing-angles/td-p/3945...
The quality of the screen on an X120e is below expectations.
This is common with low-quality TN panels not helped by glossy displays. My personal X120e screen likes to bleed certain colors of red.
Solution (not really):
One can use the Windows 7 built-in color calibration tool to adjust the colors to make it more tolerable. Adjusting your own viewing angle in relation to the screen might deal with some color issues (hard to figure out what's the correct viewing angle because of TN panel's small range of optimal viewing angles). Also, changing the refresh rate to 60Hz may deal with some headaches due to the screen (as it did for me).
HDMI Overscan to HDTV issue:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/HDMI-overscan-to-HDTV-issue-on-x120e/m-p/395335
There is a black border when outputting to HDTV through HDMI.
Solution:
AMD's CCC by default sets a specific value for overscan / underscan. One can http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/Output-to-TV-via-HDMI-port-black-border-on-the-... while the device is connected via HDMI (the option is hidden if the HDMI port is not used) and adjust the slider to an acceptable value.
Skype asserts after 10-20 seconds of video chat:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-Skype-quits-after-10-20-seconds-of-video/...
When doing a video chat, the video feed will freeze and then skype will crash to desktop.
Solution:
Version 5.3 of Skype seems to be the culprit. Until Skype itself is fixed, one can use Skype 5.2.60.113 from http://www.filehippo.com/download_skype/changelog/9465/ to bypass this issue. Just reject any offer to update to 5.3 after installing 5.2, for now.
If there is anything I missed, please respond and I'll update this post with new information. These are the ones that I have encountered so far with my Lenovo X120e. Don't get me wrong, I like my X120e... it's just been a "learning" experience lol

Please help with my iphone 4 ipod app?

Hi everyone, I am having problems with playing podcasts and music on my iphone 4 (IOS 4.3.5 8L1). The symptom is that the podcast skips or doesn't play at all. Music is similar.
I have had the phone replaced by Apple once, and have been to the genius bar 3 times and spent hours on the phone to Apple support.
I have done DFU restores on the phone and downloaded the entire IOS update several times, the firewall, AV and ad aware all disabled on the computer (windows 7 BTW) during the download of both the IOS and subsequent podcasts.
Directly after a DFU and with no apps installed, sample podcasts (that had experienced problems) seem to be OK. I then installed the apps one at a time and tested the podcasts in between, I installed the 6 apps I find most useful. I then downloaded more podcasts and the problem returned after the ipod app on the phone "lost" some podcasts that were shown as being on the phone in iTunes. Resyncing meant that the podcasts were shown but the problem of skipping etc. had returned.
Today I went through the same process and got the same result, but with different podcasts. Similarly, the ipod app "lost" some podcasts before resyncing corrected that part but started the "skipping" fault.
Other things I have done:
The podcasts all play correctly on iTunes, and also on my iPod.
I have downloaded the entire podcast library several times to eliminate the remotest possibility that they are corrupt (this would manifest by them not playing correctly in iTunes/iPod I would imagine as well).
I have had a iPhone 3GS for a while and also an iPod, so I am familiar with the products, and never had a problem.
I have logged a case with Apple and am now at my wits end, because it seems that getting any sort of ownership is a real problem.
Any suggestions on what else I can do?
Many Thanks,
Neil
BTW: iTunes 10.4.1.10

Lines appear around transparent objects!

Hello,
I think my previous post on this topic was lost somewhere in the adobe forums machine, so please excuse my repost.
I've noticed that exporting layouts from InDesign CS3 that contain transparent graphics causes the resulting PDF to show DARK LINES AROUND the transparent objects (at the transparent border). I've been using all compatibilities (1.3--1.7), and found that the lines appear on any PDF set to 1.4 or above. (1.3 doesn't have the lines, but it shows stitching lines (white lines) around the entire transparent frame box, so it's unusable.)
If I zoom in and out with the reader, I see the lines come and go, but don't want users to see a poorly rendered PDF at ANY zoom level.
How can I create a professional looking PDF without lines at the transparent borders?
thanks,
JP

Thanks for the reply. That thread was helpful in showing some of the effects that I'm seeing (e.g., turning off "image smoothing" in the Acrobat preferences helps). However, I'm still interested in producing a clean looking PDF that doesn't contain dark pixels all around the edges of the transparent images.
To show what I'm talking about, I've posted a picture of screen captures with explanations at: http://www.viveredesign.com/images/example3.jpg
This effect only appears when I export a PDF with the Compatibility set to anything above "Acrobat 4 (PDF 1.3)" (so it only looks good with the oldest item in the list).
If anyone has a suggestion on how to create a PDF without this effect, please let me know. I know I can always just put the blend in to the original image, but that seems so 1990's ;)
thanks,
JP
