Minor Display Problem - Blue Lines

Hey All,
BootCamp with 10.5 looks awesome. Im having one problem - my display is slightly off - its showing some strange blue lines, for example when I hover my mouse over the tabs at the top of apple.com, or at the top of these pages on the 'store', 'Mac' Etc. Have tried changing the display settings to no avail. Has anyone else got the same problem? Have updated all drivers also.
Thanks!

Display problem - blue tinge, low res

My first gen 20" intel imac has an odd display problem.
The screen has a light blue tinge to it which show up particularly clearly in finder windows which i have set to display white. I've played around with brightness/contrast settings as well as colour calibration but to no avail.
This problem started a few months ago when it would periodically flick between being normal and this blue tinge. For the last few weeks the blue tinge is all I get.
The other symptom seems to be a reduction in resolution in 'blue tinge mode' which is particularly noticeable when watching movies.
Does anyone out there have any ideas?

does this problem occur on external screen?

Mac Pro (early 2008) NVidia 8800GT display problems (blue/green lines)

I see others have touched on this topic a bit but not quite the same as my problem
Every 2 - 3 days, I have to reboot my Mac Pro because my display starts showing the dreaded blue green outlines and lines..
I've called Apple (of course they are not going to admit that others have this problem) and they told me to reset the PRAM, which I did to no avail of course.
I've had this card for 3 weeks, and they are telling me that I need to bring my mac pro to the apple store. Yeah right, like I can afford to bring my computer in a for a few days, when that is what I use for work everyday (computer programmer).
When I asked them to replace the card, they told me I have to bring it in, then I told them they can just send me a refund and keep this crap. Which the support rep said, I can't authorize that. Hah.. Apple is really digging on my last nerves these days.
I did not have this problem with the stock ATI.
Any suggestions would be appreciated.. I've run hardware tests off the Apple DVD and using techtool pro, nothing fails.
I've heard reports that this card is a major dog (slow) in leopard, that the ATI actually out-performs it, anyone else here anything like this?

What monitor are you using it with? If it's a 30" Cinema, this problem has been around for a couple of years without any resolution - there's a long thread about it in the Displays forum.

Display Problems Vertical lines

Ok i have a G4 12 inch, first i had an inch wide block from top to bottom on my screen that shows as very light blue when on a white background, This First occured about a week after my years garuntee had run out, i would have opted for Apple Care had i not pushed the boat out to buy the powerbook g4 titanium.(if i had brought the ibook i would have had enough cash for apple care). My local apple store said i would need to buy a new screen wich is not an option for the money they want.
This morning i shut the screen and when i reopened it i had a pixel wide red line running fron top to bottom. Great as the machine is only 18 months old and i take great care of it.
i dont even use the laptop daily so i am a bit upset and the money i am being told i must give out for a new display.
Is it the display at fault or the graphic card?
The Machine has never been knocked about, and reading these threads i am surprised at the amount of people that say you should expect it with an lcd display.
Why i ask? as i have a Dell for work my girlfriend has a cheap Acer and this is not my first laptop and i have never ever had a problem with a display before.

As for your other aspect of your question, it is being addressed. People are getting their machines fixed. Those who are not either got a repair person who does not recognize the issue for what it is, or the problem is so intermittent as to not make it easy for them to see the problem. You should always hold on to a case number when you call AppleCare. That way, you can be sure they are tackling the issue as it is and not some other problem. I would add this discussion does not let you discuss Apple "policy" as terms of use dictate on the right:
"2. Submissions

Since this is a user to user forum, I suggest you stay within the confines of those posting restrictions. Don't ask why something isn't getting repaired. Get it repaired through the proper channels, and make sure they follow through with it correctly.

Unibody Macbook Pro 17inch Display problems, vertical lines and artifacting

Hey everybody
I bought my 17inch MBP at B&H in June (week before WWDC, D'oh) and it was working fine until I came over to Ireland to work on a editing job for the summer, as soon as I attached it via mini display to a second monitor I started getting artifacts and vertical lines in certain shades and colours on the macbooks display, its gradually gotten worse so much so in fact that it is nearly unusable.
I have seen the thread about the firmware update, but my computer is already up to date with that but it still has this problem, I contacted apple and was told to take it to the apple store and the genius bar in Belfast, as helpful as the rep was he told me it would be two weeks for a repair, by replacing the logic board. Which I just can't do as I've only got three weeks left on the job and need my mac every day. I've searched and it seems no-one is having this problem except me since the firmware update, but clearly my machine still has problems.
Never had a problem with all my previous Mac's but I'm close to tossing this in the bin please help because if I can't get this solved I will have to move to PC and install my copy of AVID on it as this is the only other available computers at this production company.
What to do? Has anyone else had this problem recently? Or know of a fix for it? I've tried everything downloaded the firmware told me its already installed, switched the graphics displays etc etc
Please help
Thanks

Welcome to Apple Discussions!
It sounds like there is a hardware problem of some sort with the graphics chips, and the only real fix is going to be to replace the logic board. So at some point, you will have to send your Mac off for repair.
In the US, you can sometimes arrange to get a loaner. You might ask if this would be possible where you are, since the repair is going to take so long.
Unfortunately, I don't know of anything that would fix your problem other than a repair.
Good luck!

HT3964 my imac 27 display has 5 blue lines and does not boot up what is the problem?

My Imac 27 displays 5 blue vertical lines and does not boot up. What could cause this?

I already anticipated the video card causing this issue. This was confirmed today by Apple issuing a campaign indicating the AMD Radeon 6970M video cards are defectivce and will be replaced free of charge three years from date of purchase. I looked at the new iMacs and found repairing them to be a nightmare. So, once this p.o.s. is repaired, I'm selling it and purchasing an ABA computer.

I scanned an old image using my Epson NX515 printer, used GIMP to make some minor repairs on the image and printed it out. I noticed there were a number of evenly spaced thin blue lines across the image, approximately six of them.

I scanned an old image using my Epson NX515 printer, used GIMP to make some minor repairs on the image and printed it out. I noticed there were a number of evenly spaced thin blue lines across the image, approximately six of them. I opened & printed the image on my PC using PAINT.NET. No lines appeared. I sent the image to my daughter. She printed it and found no lines. I printed the image using Seahorse on my Mac and the lines still appeared. I used basically the same print settings on Mac and PC.

did so now, only now I'm getting a slightly different error: could not find udevd no such file or directory. I checked both grub.cfg's and my mkinitcpio.conf and there's no listing for udevd ....which I've never heard of, so I assumed it was a typo?
For clarification: udev is in the mkinitcpio.
I'm not sure whether I yet have a good intuition for how you have your machine set up, but I suspect you need to include a cryptdevice flag to the kernel in your grub config. The file isn't found because the kernel doesn't know your root directory needs decrypting first.
My setup is an LVM over LUKS over LVM sandwich. To boot into my system, the grub.cfg contains the line:
linux /vmlinuz-linux root=/dev/mapper/cryptvg-root cryptdevice=/dev/mapper/vg-crypt:root rootfstype=ext4 pcie_aspm=force acpi_osi=Linux acpi_backlight=vendor i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1 ro
Now, most of those flags don't have anything to do with your problem, but note the cryptdevice. It tells the kernel it's dealing with an encrypted filesystem sitting in a logical volume called crypt on a volume group called vg. The bit after the colon tells the kernel to associate this encrypted filesystem with /dev/mapper/root.
As for how to fix your system, I'm afraid I still feel a bit fuzzy about how your LVM and encrypted layers relate to each other, whether you have LVM over LUKS, or LUKS over LVM, or something else. Was there a particular how-to that you followed?

Had my display 2 days and i have a blue line right side

Seems the display has a blue line right side which i know others have had the same problem. Surely i can take to local Apple store for replacement ? i booked genius appointment. Any comments would be nice!

Your screen has been the unlucky victim of a random defect in the bond between metal and glass on the LCD panel. An LCD display is based on millions of semiconductors deposited on the whole glass area of the LCD screen most of us are all looking at right now while reading this. Other electronics required to drive the transistors on the LCD panel are located on conventional circuit boards with copper metal used as conductors or "traces" to connect all the electronics together. Getting metal-based traces to hook up to glass-based electronics requires special bonding techniques. As you can imagine, you can't just use a soldering iron to attach a metal wire to glass.
It's a tricky process but one that the LCD manufacturing companies had to overcome to make LCDs a mainstream technology. Unfortunately, defects do happen in numbers measured in very low occurrences per millions and millions produced. Yours happens to be one of the unlucky ones.
Since it is so new, Apple may do an in-store replacement of the whole assembly for you. Or they may do an on-site replacement of the screen, so you shouldn't be too greatly inconvenienced by, for example, having them send it away for a repair. At least that is how I believe it will be handled. Either way, they should know that it is a screen defect and that replacing the main logic board or controller board will not fix the issue. The screen is what needs replacing.

Vertical blue lines on external Thunderbolt display

I use an Apple Thunderbolt Display connected to a 27" iMac using OS X 10.9 (Mavericks). I've been using this set up since last June, but in the last 30 days or so I have noticed that vertical blue lines started appearing in the Thunderbolt Display. It started with one single pixel wide line at first, but now the section with vertical blue lines is about 2 inches wide. The lines are not always there. It happens mostly in the morning.
The display is still under Apple's warranty, but I wanted to find out if there's anything I can do to fix the problem before deciding to take the display to the nearest Apple Store.

If touching the tab can make the problem go away, perhaps you can put a piece of compressible material, like weather stripping, in the assembly such that when you bolt it all back together the material keeps pressure on the tab same as if you had your finger on it. OK, that's a long shot. But there is no other way to restore a failed tab bond that I am aware of.

2009 iMac Blue lines and crashing - Apple replaced graphics card but same problem occurs? Any advice?

Hi all,
So Ive had my iMac 2009 model for a fair few years, and barring getting the hard drive replaced a while part as part of their program, no troubles. Then a month or less ago, I got this weird crash during work. Small cubes of vertical blue lines appeared all over the display and froze everything. The arrow cursor still moved but had to hard reset. Then it would just constantly freeze and the blue cubes appeared again on startup so I could only get in using Safe Mode.
After browsing the web, I heard a backup restore might fix it, which it seemed to, but then it kicked in again. Took it to Apple who could see no hardware issues and the problem didnt occur while I was there because of the restore, it was more intermittent. So I took it home and it happened again.
This time at the Apple Store, they told me it was definitely the graphics card and took it in for repair. Service was great and a few days later I get it back, pay for the repair and come home. All fine and no problem for a couple weeks.
Yesterday it kicks in again! Same problem, cant boot at all outside of Safe Mode, which is erratic, has 5 columns of blue lines across the screen and Mail flickers like ****.
Ive booked it in AGAIN at my local store to check, but my question is does anyone have experience of what this could be, and also if the first repair was wrongly diagnosed and didnt fix the problem, will Apple refund that, or offset it against the actual repair if something else needs replacing?
Any help or insight would be greatly appreciated, all the best!
Leo

new card or not, I guess only Apple themselve will know, but Apple Authorised Service Centre can only replace with original card. you may consider to get your fan replaced too, as your iMac is getting old now and the fan might be getting weak to cool your system down.
well, this is only a suggestion. I've been an IT technician for years, and I do encountered graphic card keeps failing till we changed the fan, just sharing my experience.

Blue line at the bottom of my display

My MacBook locked up (I couldn't eject a DVD nor could I turn the machine off) so I had to remove the battery to turn the machine off. When I turned the machine back on (1) the MacBook's display remained dark and (2) my Cinema Display had somehow changed its display resolution to 800x600. I fixed the Cinema Display's resolution easily enough and got the MacBook's display running by changing its resolution to 1280x768 (60 Hz). I don't know what the original MacBook display resolution was, but 1280x768 appears to be it. The problem is that now there is a half-inch wide light blue line running across the bottom of the display.
What should I be doing to get rid of that line?
Any help is appreciated.
Don

The computer appears to have worked out the problem itself. After hitting "Close" and then restarting (as opposed to selecting "Restart"), the display menu came up with "Cinema Display" and "LCD Display" windows set at 1280x800. Everything's back to normal. The puzzling part of this was that prior to shutting off the machine, the display menus were "Cinema Display" and "Display" (not "LCD Display"). I don't know where the "Display" window came from, but now it's gone and things work fine.
Thanks,
Don

Wierd lines on my display and frequent lock-ups w/ and w/o display problems

When booting I sometimes get weird lines and blocks on my display (the GRAY Apple screen) and then it hangs, other times the computer will boot and run fine for 20-30 minutes and then the display goes wonkers with blocks and lines and the computer does not respond. The only way I can get it to boot is to reset the PRAM by letting it CHIME 3x and then occasionally it will boot without issue and run, while other times I still get the blocks and lines on the display.
When I am able to get it to recover and re-boot after the lock-up and display problems and occasionally the box in the middle asking me to re-boot similar to a kernel panic the OPS gives me the option to REPORT the error and here is the error for others who would know more...
Thank you in advance,
Darren

Anyone know what is causing my problems? I thought it was heat so I downloaded a CPU and FAN temperature monitor and the CPU was getting VERY HOT at first so I then ramped-up the CPU FAN SPEED to maximum - it turns out the CPU FAN was not rotating well at low speed - since then I have cleaned and checked the fans and they all work as they should and blow on high(er) when the CPU temperature is above a certain level.

Is there a kb article or something that would illuminate what to look for in these logs, or is it a matter of learning by osmosis?
Both. I am not skilled in reading logs. It is a very technical and time consuming task for the uninitiated (me!) In scanning a log I look for the backtrace and loading dependencies. The first item in the backtrace is usually the roadblock.
Beyond that you can look at the Technical Note TN2063: Understanding and Debugging Kernel Panics

Hello -
My iMac has developed a video display problem. Everything now appears in a strange, cartoonish way. Purples, greens, blues. Can this be fixed, and if so, any idea how much it might cost? Also, could I output to a seperate monitor? I plan to replace the unit , but cannot right now. Thanks!

Go to System Preferences > Universal Access > Seeing.
In the Display area, reset it to "Black on white" by clicking that checkbox.
You can also reset it by pressing Command-Option-Control-8

If your iPod Touch, iPhone, or iPad is Broken
Apple does not fix iDevices. Instead, they exchange yours for a refurbished or new replacement depending upon the age of your device and refurbished inventories. On rare occasions when there are no longer refurbished units for your older model, they may replace it with the next newer model.
ATTN: Beginning July 2013 Apple Stores are now equipped to do screen repairs/replacements in-house on iPhone 5s. In some cases while you wait. According to Apple this is the beginning of equipping Apple Stores with the resources needed to do most repairs for iPhones, iPads, and iPod Touches that would not require major replacements. Later in the year the services may be extended as Apple Stores become equipped and staffed with the proper repair expertise. So, if you need a screen repaired or a broken screen replaced or have your stuck Home button fixed, call your local Apple Store to see if they are now doing these in-house.
You may take your device to an Apple retailer for help or you may call Customer Service and arrange to send your device to Apple:
Apple Store Customer Service at 1-800-676-2775 or visit online Help for more information.
To contact product and tech support: Contacting Apple for support and service - this includes international calling numbers.
iPod Service Support and Costs
iPhone Service Support and Costs
iPad Service Support and Costs
There are third-party firms that do repairs on iDevices, and there are places where you can order parts to DIY if you feel up to the task:
1. iResq or Google for others.
2. Buy and replace screen yourself: iFixit
