2 years ago I had bought this iMac 2GHz Intel Core 2 Duo and its on version 10.5.3. It came with tiger and when I installed leopard I started getting all these red pixels. I have no idea if its a software problem or hardware problem.
View 10 Repliesfor the last week or so my MBA has been showing a ~3 inch bar running vertically along the middle-left of the display. Until today, the area looked just like blurry pixels (some things like graphics would still appear, so I don't believe the problem is with the pixels themselves). Now the area has become a gray bar of pixels.

My first thought is that the Graphics Card is going bad. Odd thing is, though, that I captured this via screen capture from another Mac. Could it still be a bad GPU if it looks this way remotely? I'm not sure how these early Mac Pros work. I have Mac minis that, when the display is off (or headless), the GPU is not used to render the GUI via screen sharing. So, I tried disconnecting the display from the Mac Pro, and I get the same screen shot.
I can boot the Mac Pro into Safe Mode, but that is it.

Over the last week, my 7 year old Powerbook G4 began showing faint pixels in the background which is more obvious if you are scrolling over menus also when a menu is highlighted. Unfortunately this seems to be affecting DVD playback because it will show blinking green vertical lines inside Front Row. This image within OS X 10.5.8 will show what I mean: [URL]. Does this means the graphics card is failing?

This is a MacBook Pro pre-unibody The graphic card is an ATI Radeon X1600 I ran the TechTool Deluxe tool to test the video RAM (and everything else), but it didn't detect anything wrong I have never seen this when the laptop is connected to an external monitor This doesn't happen that often; say 1 times out of 10, usually after the laptop comes out from sleep. The issue stays for a few minutes and then goes away until next time, so I am unlikely to have the problem when I go to Apple Store for service.
So I have this collection of pixels near the bottom of my screen but they're only visible over a dark grey area, like when you're in the login screen (I have an early 2013 MBPr 15 btw)
It's probably a problem with the screen itself and not the GPU (or maybe the connection between them?) since if I take a screenshot it's not visible and I've connected it to an external monitor and it doesn't have it.
I took a picture of said problem [URL] .....
I've had this for a few weeks now and I've tried those youtube videos (I just to have some image retention after leaving something to run for a long time) which have decreased the amount of pixels. They all dissapeared for a few hours and now they're back.
I'm on my third LED Cinema Display (for various issues) but I've noticed all of them have DOZENS of very tiny specs of color that are only apparent on a black screen. Furthermore, they seem smaller than an actual pixel (have to be up very close) and they are only apparent at certain angles (and even sometime change color) as opposed to dead/stuck pixels. These always pass my initial dead pixel check over a full black or white screen but I find them once I get in real close.
View 2 Replies View Relatedjust purchased an NEC Spectraview LCD2690WUxi2 display (1920x1600 26" LCD SIPS panel), and fonts are aliasing strangely, almost as if they are not falling "on the pixel" in the OS. It's not a "big" problem but is clearly noticeable in my transition from my 23" cinema display. This is particularly evident with small fonts or italics. I'm really hoping that there are settings either in OSX or on the display that can fix this issue. Images look absolutely fantastic BTW�tack sharp, no banding, phenomenal color. In that respect this blows my old 23" Apple display completely out of the water. So it's likely something in the OS, no

I have had my MacBook for just over a year. A weeks ago, the display started go weird: - strange shapes started appearing on the desktop - a fluorescent green (like vertical strips of 5 or 6 pixels in a group), sometimes as a shadow of a previous open window, sometimes just random squares or lines. The blocks of green go if i run my mouse over them with the button pressed down. -a fluorescent green light sometimes shines around the programme tiles in the dock. -shadows behind open windows very accentuated and fluorescent green - sometimes text on web pages and documents look garbled - again this goes if i run my mouse over them, and either go or comes back in a different place. Some times i can go a few hours without experiences these problems, other times the issue is there on start up. I ran the quick hardware check, and no problems were reported, a week later i ran the extensive check, and again the system seemed fine.
View 1 Replies View RelatedSo after waiting 4 weeks my High-res Glossy MBP FINALLY arrived...I was so happy. Got home switched it on and WOW it really is a beautiful machine...After using it for about 30 mins however i noticed a small dot to the lower right half of the screen... I looked closer and realized it was either a dead or stuck pixel( I dont exactly know the difference). I did a few test on it, and its ONLY visible when a light color is on the screen (White, Gray etc) However when the screen is DARK blue, Dark green or black it cant be seen at all...
It kind of looks like a TINY speck of water or liquid the size of 1 pixel stuck under the glass... I noticed that it does get lighter and darker when i adjust the brightness of the screen. Can anybody give me some tips? Anything i can do to fix it? Is it in fact a dead or a stuck pixel? I tried the JSscreen fix which is basically a online tool that opens up a flashing screen...Ive had it on for about 30 mins...but no luck
I've got two iMacs in my posession currently from getting replacement machines. Both have screen issues as follows: iMac A - dead & stuck pixels, feint grey horizontal bar running along bottom portion of screen, bottom left corner has noticeable backlight bleed. iMac B - dead & stuck pixels, yellow tinge in bottom portion of screen. So here are my questions. Which iMac should I keep and submit for repair? (does it matter and why or why not?) How does the actual repair get done? For example, if I submit iMac B for repair, could I end up with a grey bar or backlight prob like in iMac A?
Are there multiple layers to the display when they fix specific issues? For example, let's say the dead pixels are on one layer while the yellow tinge is on a different layer, or are both issues on the same layer? I ask because if there are two or more separate layers, there is more of a chance to mess up so I may want to submit the iMac that has the least amount of issues.
Lastly and most importantly, has anyone submitted their iMac for screen repair for these issues and got it back 100% repaired? (no dead/stuck pixels, yellowing, grey bar, backlght bleed) These are #4 and #5 in terms of the number of replacements I've gotten now and I'm sick of it so I may opt to go for repair on either of these existing machines instead of going for replacement #6. But do you think a 6th replacement would be better than going for repair on either of these? Or not?
My mid-2014 15" Macbook Pro randomly "loses" its retina display at the top menu (becomes pixel-y), where the battery, sound, and wifi logos are (on the top right side of the screen). A restart fixes the issue, but I want to know if this is an issue that can be fixed?

View 8 Replies View RelatedWhen I took my new Imac 24 out of the box last week, instantly i noticed about 3 or 4 dead pixels, they aren't too bad but it's only of those things you don't expect with a new computer and it can be quite distracting once you know they are there.... if i were to contact the place of purchase in regards to this do you feel i would be over-reacting to have it replaced or repaired or should i just suck it up?

View 12 Replies View RelatedI recently noticed 4-5 dead pixels (gray, not fixable with software) on my 1.5 year old MBP (see sig below). Definitely a bummer as I had to go through 2 MBPs when buying this computer just to get one without any dead pixels. I don't know why or when these pixels died. I have AppleCare and I am wondering if Apple will do anything about this. Is there a threshold for repairs (e.g., only 10+ pixels is repairable)? Has anyone ever got a repair/replacement for dead pixels? Is there anything I can myself to fix this problem?

This is a screenshot straight from Photobooth, showing the image from my iSight when the black cleaning cloth is held up to it. No, those marks are not dirt (on the outside anyway). Other that this, my iMac is fine with the exception of a single dead pixel (I thought this was a thing of the past, but oh well) and I'm not 100% about whether or not I have the yellow screen issue, so I'll ignore it for now.
View 3 Replies View RelatedI don't have an iMac, but I do have a 24" ACD that I bought brand new a few months ago (not refurb). It has a single pixel that is constantly on and it's red. It drives me absolutely CRAZY...probably because I paid $900 for this display. I can't remember ever having a problem pixel on another display...all of them cheaper. So I'm curious about the iMac owners. Is a dead/stuck pixel here and there an expected thing for iMac owners?

View 8 Replies View Related2 weeks ago I finally decided to order an iMac, despite all of the issues I had been hearing about with the display. I figured that I was going to be one of the lucky ones and have no issues whatsover. I was ordering a brand new machine and it should be fine.After about 30 minutes of getting things up and running, and while a webpage with a good bit of white background was open, I noticed the dead pixel (pixels?). As the question mark shows, I'm not really sure if this is considered one pixel or many. So I figured I'd let the gurus like Hellhammer tell me. The first picture is zoomed out and is of the bottom left hand corner where the dead pixel(s) is. I apologize for the spots around it, that is actually inside the camera body itself I think (Nikon D40x) and I can't seem to get them cleaned off. That's another issue....sigh. The second is a very close in picture of the area. I photoshopped the lense spots out to see it better.Individual pixles are visible. This to me looks like 5 dead ones in a diagonal row.

The retailer has a zero dead pixel guarantee on monitors so I'm going to hope that covers laptops too.

I'm in the UK and I was told it would be shipped from China and arrive in a week and a half, but instead it turned up from Ireland the very next day! After unboxing it I ran all the tests.. yes, call me a sceptic and tell me I'm looking for trouble! No yellow screen, no grey shadow, no scratches on cds, no dead pixels on photo booth. So far so good. I could swear my Superdrive is making an odd off-key noise when accepting discs, but second opinions tell me it's normal. The Seagate drive can make 'processing' noises every now and then but it doesn't bother me too much. I think in Europe we're stuck with Seagate for 1TB from what I've read here
