IMac :: 27" Backlight Bleeding Along With Yellow Screen
Jan 1, 2010
I have not seen any posts comparing these two symptoms together, but I am wonding if both exist on the same screens, or if they are infact seperate issues. I returned a 27" iMac i7 because it had both slight yellowing and terrible backlight bleeding. I have seen multiple machines first hand (3 Core 2 Duos week 41s) at different stores (Apple and Best Buy) that had no yellowing and no backlight bleeding. I won't get into how to check for yellowing, you can read about that issue here: [URL]
But to check for backlight bleeding is both easy and impossible not to see if you have it. To check for backlight bleeding, a quick way is to bring up a site like http://www.blackle.com/ or any other black background, and check for an inconsistent white glow on the edges of your screen. I had serious backlight bleeding in the lower corners of my screen, which happens to be where the yellowing was happening. I don't know if they are related, but hopefully we can determine if there is any correlation here.
I did order a second machine, because I know Apple knows how to make a 27" iMac with a perfect screen (as advertised), since I have seen 3 of them in the wild. Hopefully they will be back to the quality that they had is their early production units very soon.
How common is this? I prefer darker backgrounds and this may be an issue.I'm over the yellow and the buzzing, but this too? Don't take me the wrong way - I love my Macs but I can't say I'm crazy about this..See attachment. Ignore the image noise, the big spot that bothers me is on the top to the right.
Alu 24" 2.4ghz when they first came out with aluminum, got it at the store. since august 07 My imac had a small yellow tint, i noticed, when i got it and it was not worth anyhting screaming about, i also noticed it had bleeding issues ath the bottom and sides. I wanted to return it or trade but i was convinced out of it.
Now i noticed that from left to right their is a prominent yellow tint streaking it's way across and fading around the half way point.It is irritating and sad to see this display on this mac was ok, at first but it is geting slightly worse.I have apple care, can i trade this/replace it at an applestore, or would they need to fix it?
I've had my new 13" MBP for about a month now and I am noticing what looks like backlight bleeding spots at the bottom of my screen. It is most noticeable on the bottom left and appear blue-ish on a black screen at maximum brightness. It is getting irritating when I am watching movies at night. I have the 9CBD screen. Others have said they have no problems with this screen model. So is this normal or is it a defect? If it is a defect, what can I do to fix this? My 14 day grace period is over, so I'm assuming an easy exchange at the Apple Store is out of the question?
So I got my 24" Cinema Display 2 weeks ago and just noticed this backlight bleeding on the bottom right and its really pissing me off when I watch movies or use frontrow.Does anyone know the best way to go about with an exchange or something?
Just received my new imac today and everything is perfect, quiet drive, no stuck pixels excellent apart from some bad backlight bleeding which can be seen on black screens. It's particularly bad at the top and the sides.... Does anybody else have this and should I risk sending it back??? I have a 52 inch lcd sony and that doesn't suffer at all from back light bleeding...
I just received my new imac 27, i7 (28-06-2010). I ran the screen test, unfortunately my screen has yellow tint issue. I have ran all updates and firmware within apple update with no luck. Going to call Apple for a replacement!
I have a week 50, i7, 2TB Imac. It has a very distinct yellow "tinge", and the Bluetooth does not work properly. Every time I reboot or start, the "Bluetooth setup assistant" starts, which I have to force quit. The wireless keyboard and mouse work fine, but I can't add either of my two bluetooth headsets. They pair, but when I try to activate them, it goes to the bluetooth settings screen, where it says that bluetooth is "off", despite the on checkbox being checked and the keyboard and mouse working. I called support and they had me do a bunch of things, the last thing being reinstalling the OS. Didn't work. So now I need to call them back. I have two problems, the yellow screen and the Bluetooth. Should I ask for a replacement? I see that a lot of people have gotten a replacement just for the yellow screen problem. I have two faults.
i bought the 2009 refurbed 27"er and returned it 3 times due to yellow screen problem. for the 4th replacement they decided to send me the new model.
i have the 3rd and 4th replacements sitting here side by side.the 3rd replacement, which has a yellow corner is light years better than the new one. the new screen doesn't have yellow corners...it's a perfectly consistent yellowish brown tone. the older one has a yellow corner, but is much more illuminated and very balanced white. the max brightness of the new one is only 3/4s of the max of the old one.i tried configuring it to no avail.
are all the new models like this?it's quite a bit snappier, but the screen is worse than the last 3 that had yellow patches? it almost seems like it was a return and it shipped from cali rather than asia?
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?
I have an eyelash-sized dark streak on the center, bottom (dock area) of my Powerbook G4 15". At first, I thought it was dirt, or another external blemish, but if I move the cursor over it, it obstructs the view of the blemish (instead of appearing beneath it.) Also, I have a small, almost white, faded dot which appears to grow and expand larger if the Powerbook is running for longer than 4-6 hours.What is frustrating is that neither show up under screen captures. Is my monitor full of external stains and blemishes which I cannot remove, or is there something actually wrong with my display?
I just bought a new unibody Macbook (YAY), but when i play full screen movies, at the bottom of the screen you can see the light shooting up. Is that worthy of a replacement? Or is that normal on a LED screen? I just purchased it yesterday, so I can just go exchange it if its neccessary.
I did a search and could only find information about the last rendition of mbps, and I see they had problems with bleeding along the bottom part of the screen. I just got my umbp a week ago, but I've been so busy finding a place to live for grad school that I haven't had the chance to use it. I looked at it in the dark yesterday, and I'm super anal. I saw a small amount of backlight bleeding on the bottom left corner of the screen, perhaps half an inch on the left side of the screen, just in one area (not along the entire left side).I wish I could take a picture, but my digital camera is nowhere to be found. Is a small amount of backlight bleeding acceptable, or should I exchange for a new umbp?
I cracked my laptop screen and along some of the crack lines there is a blue, magic marker looking bleeding going on. It has been getting progressively worse. The menu bar on top is fully covered in blue. The blue coloring migrates. My question is, will this destroy the inners of the computer in any way? I am trying to wait for the updated MacBook Pros, but don't want to wait if I am risking frying all my info. I can still use the computer, I just have to move screens around so I can read around the blue blood.
I just got a new 1.6 MBA but it is going back tomorrow. It has screen bleeding showing like mountains on the bottom and top of the screen. In addition, it is HOT (CPU 63-83 C). Way hotter than what I tested at the store (CPU 40-60 C). In addition, it has a tiny flicked (ripped) paint at the back which I am somehow ok with. I just wanted to share this with you and know if any of you facing similar issues? I have never ever seen screen bleeding in MBAs before since the MBA has the "best" screen ever. I hope that I'll get a better replacement.
I've got an 27" i7 which has got a significan amount of light bleedthrough from the LED backlight in the upper right side of the screen, about 5 inches from the far right. I don't have access to the display currently, but will take a photo when I get home.
It's not an annoyance when the screen is displaying bright colours, but when the screen is supposed to be black, the amount of bleed is quite visible (this is bleed down into the screen, not through the joins/seams of the unit).
Very much similar to the examples shown in this thread: [URL]
Specifically like [URL] except for being on the top right side of the display.
Does anyone else have these issues? I realise that it is impossible to get it perfect, but this could turn into an annoyance for me, and just want to know if anyone else has a similar issue.
I also dont' want to run against Murphy if I have to send it back, as the one I have isn't suffering from anything else...
I have a late 2006 Macbook, and my dad has an early 2009 Macbook. I was comparing the two today and noticed that there was a significant difference between their LCDs. My dad's Macbook has a lighter, more normal display. While mine has a yellow tint to it and is darker. Both computers were on the same display profiles and both had the same brightness set.
Is this just how LCDs are as they age? Or is mine really not supposed to have that yellow tint? The new Macbook is on the right in the pic.
My Air's screen is slightly darker at the bottom (only on a few millimeters, but still). It only happens on a white/light background though (I don't have my dock at the bottom). In comparison, the screen of my MacBook has a very uniform backlight. Does anybody else have this issue?
I sent an email to Steve Jobs about my yellow tint 21.5 iMac issues (three exchanges, all affected, resulting in a refund). I got a call from Dena at Executive Care within 24 hours.
She said they are aware of the problem and do not know how widespread it is. According to Dena, the issue is not resolved and that ordering a new iMac will not result in a fixed display.
She said the engineers are working on it now and they are not sure if it's hardware (most likely) or software related. Further Apple stores cannot do repairs because they haven't determined what the issue is.
New here to MacRumors. As the title states, I have a G4 eMac(all white sort of cone shaped) that has a screen that is progressively getting worse. User says it has been gradually getting worse since the Summer. Has a very heavy yellow overtone on any window in the foreground, and some blue etching in the background. I did a search and found plenty of info re: the LCD iMac, but found nothing about this in the eMac? I ran the colorSync utility, and no dice.
I kept my macbook (late 2008) turned on overnight on lowest brightness and when I tried turning the brightness back on this morning, the backlight flashed on for less than a second and then turned off again. Somehow I managed to get it to work, but whenever I move my macbook even slightly the problem reoccurs. I've done some research on my problem and I suspect that it's hardware related (maybe the inverter or the inverter cable?), but maybe the LCD itself is broken? Does anyone else have any experience with this?
I was using firefox today (all I had open was facebook and gmail) and iCal was open in another space. All of the sudden my macbook screen went black, but the backlight was still on and the music was playing. I hit the space bar a few times and moved around the mouse and the screen came on for a second or 2, but then went black again. It wouldn't come back, so I had to hold down the power button. When it restarted, everything was normal, except that now the fan is going fast and loud, and my computer is getting hot with only firefox open to macrumors.
Booted up my Macbook Pro this morning and I noticed this strange yellow-speckled discoloration at the top of my desktop screen. I'll attach a screenshot--its in the center of the screen, right below the top menu bar. What is this? Ran a complete cycle of Onyx, but it's still there.
my Macbook Pro's display has been acting up. There's these little yellow squares that keeping popping up on my screen while scrolling through something. They then disappear as soon as I scroll up or down again or open a app, tab, etc.
I read on the internet that this is probably caused by lightbult or inverter board, but that information was on macbook or macbook pro, i couldn't find any information if its the same issue with macbook airs.. Has somebody had similar situation? How have you solved this issue?
I have a 2008 White body model Macbook with 2 gigs of ram and 2.1 core duo processor. My problem is that the screen won't turn on...when I start up my computer it lights up for a second, but turns off before the apple sign shows up. If I look really close I can see everything. Oddly enough, if I press the brightness button so to decrease the brightness to the very last bar and then hit the f2 button to turn up the brightness by one, the light will turn on for a few seconds, if i continually go back and forth, I can sort of use it enough to do something with it (thank god because I had all my work for school on it). I have included a link with this thread so you can see what I mean.
