12 inch G4 Powerbook display issue

I recently took a flight and the Powerbook was fine that morning but when I got to my destination I turned on the computer to find waves in the apple on load up and the blue background had turned a pixalated blue and white. The once black background after load up is now bright lime green. and there are pixation and anti-alasising issues. It looks like the display can't do gradations and it turns black lime green. Any ideas have tried to reset PRAM many times and have gone into displays and moved the color count from millions to thousands a bunch but no luck. Any suggestions would be helpful.

Glad removing the Airport Extreme card worked. You can try wiping off the contacts with a lint free cloth, and replacing the Airport card making sure it is securely seated. Sometimes heating and cooling along with the normal handling of a laptop dislodges the card enough to cause problems. If that doesn't help you will need to get a new card.

Satellite L670D-13F 17.3 inch Notebook - screen display issues

Hi.
I've had my Satellite for almost a year, and in recent weeks the screen display has been compromised. There is turquoise/blue thin line all over anything white or white-tinged. I'd like to hope it's nothing virus-related as I have McAffee installed.
Any ideas what this could be? Is it a known issue?
Thanks.

Sounds like the red LED has gone in that display line, since RGB for white without the red (just green and blue) equals cyan (turquoise).
http://en.wikipedia.org/wiki/RGB_color_model
Try making a picture with a solid red square in a paint program and see if there are any black lines when you display it.
I have a permanent red vertical line on the display of a 9 year old Toshiba laptop. Otherwise it works fine. If the display is white you don't notice anything.
It's possible it could be graphic card related (e.g. if it's not there all the time and only happens when the graphic chip heats up) but if it's permanent it's more likely to be the display matrix.

Powerbook 17" display issues: posterization and other psychedelia

Hello,
My Powerbook 17" has, since it's purchase in June 2005, a problem with the display that occurs periodically whereby the display suddenly posterizes and becomes extremely hard to read. I have found that adjusting the display angle, that is, moving the Powerbook display hinge can make it worse or can cause it to revert to normal. It seems to me that there is a short in or interference with the wiring that must pass through this junction. Has anyone else had a similar experience with their Powerbook 17"?

Your PowerBook is the same generation as the one most people are complaining about, although the majority of affected users that have been reporting the problem have machines that were manufactured around the end of the first quarter of 2005 at the factory described as W8 in Shanghi. There are ways to find out if yours is one of these machines by doing some web searching. Stating site names here my go against Apple's usage policies for this discussion board ... sorry, but info is easy to find with a little searching.
I am glad to hear that you have not as yet experienced the dreaded lines or blanked-out areas. It is still a good idea to call Apple Care and get a case number if you have not already. Explain your problem and they may be able to help. Even if there is nothing they can do, your problem will be registered. This case number may come in handy if heaven forbid your machine starts developing more severe screen problems. Good luck!

Display Issues with mini (Mid 2010) and LG L246WP

I recently purchased a new mini (Mid 2010 base model) and planned to use it with my 24" LG L246WP monitor, which is about 3 years old. The monitor has VGA, component, and HDMI inputs.
I used an HDMI-to-HDMI cable to connect the mini directly to the monitor, and the output is completely messed up. The mini recognized the monitor (titling the System Preferences > Display dialog with 'L246WP') and set it to the monitor's native resolution of 1920x1200, but on the monitor the image is cropped to what looks like a 4:3 aspect ratio and with part of the image shifted up and left so I cannot view the top menu bar or the left hand side of the desktop. The monitor's on-screen display shows 1080p in this mode.
The Display dialog also gives me an option for 1080p. I can select this and use the Underscan slider to resize the desktop output to fit on the screen, but it is still shifted left and must be resized smaller than the available display space (plus the total image is only 1080 pixels, not using the monitor's full native screen). In this mode, 1080p also shows on the monitor's on-screen display.
I tried 1024x768 to see if I could get a properly-positioned image, but the desktop was shifted just like in the 1920x1200 case and the monitor's on-screen display status still reported 1080p.
The monitor has a menu setting under an HDMI heading with "Video" and "PC" options, but changing this selection does not make a difference.
Since the monitor came out before HDMI was as widespread as it is today, it came with a DVI-to-HDMI cable, so I also tried using that cable with the HDMI-to-DVI adapter that came with the mini, but this did not make a difference either.
To prove it wasn't the HDMI cable, I connected the mini to my Samsung 6300 series 40" LED HDTV and with some tweaking of the Underscan slider the displayed image filled the screen perfectly.
I've searched the Internet and various forum threads (i.e. http://hardforum.com/showthread.php?t=1167222&page=63) seem to indicate this monitor can send a corrupted EDID that causes issues, especially with nVidia graphics drivers. On Windows you can use registry or driver hacks to override the EDID with the correct values, but on OS X this doesn't seem possible (I was hoping for a Terminal one-liner but it seems this doesn't exist). I have seen some mentions of the shareware SwitchResX (http://www.madrau.com), which looks like it gives you the option to override resolution settings, but I haven't tried this yet.
It also appears to me that the monitor is always interpreting the signal (or the mini is always sending the signal) as 1080p, even if I've set 1920x1200 in the Display dialog. I don't know if this is a defect in the monitor where it always assumes the HDMI input is a 1080p source (previous I used it with an Xbox 360 with no issues but that was 1080p HDMI), or if is a bug in the graphics drivers (or at least a lack of flexibility / miscommunication to the user trying to handle a corrupt EDID).
I asked my local Genius Bar for advice today (without bringing any hardware in) but was not told anything I didn't already know.
I'm trying to determine the best way to work through this issue. *My questions are:*
Would it make any difference if I used a Mini DisplayPort-to-DVI adapter (and then my DVI-to-HDMI cable to the monitor's HDMI input)?
What about a Mini DisplayPort-to-VGA adapter? In the past I used a 12" Powerbook (via a mini-DVI-to-VGA adapter) with this monitor and had no display issues like this, but I'd prefer to stick with a digital connection on my brand new mini.
Is SwitchResX the only practical way in OS X to override a corrupt EDID and force the mini to output a certain resolution?
Besides the various adapters and SwitchResX, is there anything else I should try before buying a new monitor?

Hello EPWilson4984.
I have been experiencing the same issues you described. Connecting my brand new Mac Mini to my Westinghouse 24”monitor (L2410NM, 1920x1200 pixel resolution) produces a very fuzzy and washed out image quality. The Mac recognizes the monitor and applies the right resolution (1920x1200), but it looks just awful. The EDID info is definitely not right.
Now, I tried your suggestion (DVI-to-HDMI), and similar suggestions from other threads, but nothing works. Nothing seems to work at all.
The main input for the monitor is HDMI, so whatever cable I use, in the end always has to connect to the monitor via HDMI. I tried all these combinations with zero success:
Mac mini -> HDMI cable -> monitor (result: fuzzy and blurry image)
Mac mini -> displayport –HDMI adapter-> HDMI cable -> monitor (result: fuzzy and blurry image)
Mac mini -> displayport –DVI adapter-> DVI-to-HDMI cable -> monitor (result: it gives me a blank screen, no image at all)
I’m running out of options. Don’t know what to do. The 24” monitor produces beautiful, crisp images when hooked to my Windows 7 PC. It looks horrible when connected to my brand new Mac Mini.
Any alternatives you may have come across? Please let me know, thank you.

Macbook Pro Early 2011 Display issue

Hi all,
After reading the replacement program that has been extended to MBP for 15" and 17", is there going to be any news with regards to the 13"?
The reason why I'm asking is that while I'm not sure if mine is an isolated issue or widespread/common occurrence, I have had my logic board replaced last year due to a display issue, and currently still unable to run external display, despite reading up on discussion that is going on.
The symptoms mirror that of the 15"/17", just that the 13" does not have a dedicated GPU.
Hope to get more suggestions/ solutions/ news to potential replacement program from here.
Thanks all!
Regards,
Ziang

Welcome to Apple Support Communities
Early 2011 15 and 17-inch MacBooks Pro have had several GPU issues that causes graphic corruption, and it was an issue that showed in most MacBooks Pro. However, this does not apply to the 13-inch MacBook Pro, so I think it is just an issue that has appeared on your Mac but there is not a reason for a replacement program.

Display Issue after 10.9.2 update

After updating my Macbook Pro with Retina to 10.9.2 -- My display flickers for a second after sleep and or blank screen and then goes back to normal. Has anyone else been having display issues after updating?

Yes similar problem here: I have a MacBook Pro, 15 inch Retina, Mid 2012, and when I connect a secondary display via HDMI (and also HDMI-to-Thunderbolt) then the external monitor becomes the main display.
I have not figured out on how to switch back to former settings. My guess: it's a bug. A quick search confirms that many others have secondary display issues since 10.9.2
(Steve would have fired those lazy punks, who failed to do sincere testing before release …)

My mac book pro 17 inch , 2008 year , display went dark, and the steps in "everthing Mac" book did not work, any ideas?

my mac book pro 17 inch , 2008 year , display went dark after rebooting from origianl disc, and the steps in "everthing Mac" book did not work, any ideas?

The router might be bad or incompatible, but let's be optimistic.
On System Preferences, go to Network/Advanced/PPP. Only two items should be checked: Connect Automatically When Needed and Disconnect when switching user accounts. Uncheck everything else. Now, click Okay on the end of the page. The next time you're online, you shouldn't be disconnected.
If you still get disconnected like before, we might be dealing with a router issue - which can get rather complicated.

Display issue - small boxes being drawn out of place.

I am having a display issue on my desktop. It looks like small boxes of pixels are being drawn slightly out of place. This occurs across applications and just started after several months of usage without the problem. The only thing that I think really changed is I updated Google Chrome. It occurs mostly if I have a video playing on screen, but will still occur else where, generally when the screen is changing a lot (dragging windows, scrolling, etc). I can generally see that the squares being drawn are part of the video playing, but they are drawn outside the frame of the video.
I attached ascreenshot to better exemplify what I am describing. Has anyone seen this before and/or know how to fix it? I have not changed my display settings since I got the computer. Restarting the computer did not help.
Built-in iMac Display, 27-inch (2560 x 1440) AMD Radeon HD 6970M 1024 MB graphics

Thanks for your reply. After a restart, I ran Rember on all available memory. It used about 2.8 GB (out of 4GB) and passed every test.
I did manage to get a screenshot with the desktop itself being drawn incorrectly. I have seen menu items at the top of Google Chrome screw up a few times, but never for Finder.
This image looks just plain wrong:
And here you can see that the some of the terminal window is not drawn, or the desktop is drawn over it (this screenshot is while the terminal is in focus):
Are there any pure graphics card tests so I can confirm that that is what is wrong?
Thanks,

12-inch G4 powerbook 1.0GHz has kernel panics every restart

I have a 12-inch G4 powerbook 1.0Ghz machine that keeps having kernel panics every restart.
I have run the Apple Hardware Test, and this comes back fine saying there is nothing wrong with any of the hardware. I have reset the PRAM, and repaired the disc permissions.
I thought it might be a software issue, so I archived and re-installed the system software. Still didnt work. Then I tried the erase and install, still didnt work.
Is there anything else I can check to see what is causing the kernel panic. Anything else I can use to test the hardware to make sure. I have a bad feeling it is the logicboard even though the Apple Hardware Test said it was fine.
The kernel panic is also not even creating a log, so I cannot even let you know why it is causing the kernel panic. Any help will be much appreciated

PowerBook display - fade & tint over time?

I recently got a Apple Cinema Display 20" for my PowerMac, but also to use with my PowerBook. Side-by-side, the Apple Display is MUCH brighter -- more than I expect would be reasonable. I also notice that the Cinema Display has bright whites, whereas my PowerBook has a sepia/pinkish cast. Whether using the standard caliberation or tweaking my own, I can't seem to find a white point that seems white.
I've thought that the PowerBook display wasn't near as brilliant as I remember when I first got it, but the side-by-side comparison has me thinking that my nagging doubts might have some basis in reality. Something that I should take up with AppleCare, or just something I should live with?

I agree, I am absolutely sick of getting the run-a-round from apple concerning my PB17. My LCD was replace because of dark spots and failed DVI Port. The replacement LCD still has dark spot, It has Dead Pixels (where my original unit had zero) but more frustrating is that the replacement LCD has a nasty yellow/green hue that can't seem to be calibrated out. The Contrast and Color are terrible. Many telephone calls to apple including this notebook being sent in for this color issue 3 times. They say there is nothing wrong. When I look at 17" notebook models from other manufactures, I don't see these issues. This has been in so many times for repair that they should just give me a new unit. In the 20 weeks that I have owned it, I have been without it due to repair issues for 6 weeks and now I am waiting for box to ship it back again for this color hue on the monitor. The most recent return to Apple for repair yielded nothing except for 1 week of down time, and a written report stating that they feel the color issue is from "software corruption" Because of this, I formatted the hard disk drive and did a fresh O/S install only to find that the nasty yellow/green color hue is still present. The unit is scheduled to go back to apple again for this color issue as soon as a box arrives for transport. This is completely uncalled for, especially at the price of this product. I agree that suit should be considered. I know this is happening to others but Apple treats my issue like I am the only person having issues.

24 inch LED cinema Display miniDisplayPort goes black

24 inch LED cinema Display miniDisplayPort (2009) goes black with my MacBook Pro 2009.
It was working perfectly, but one day my cinema display went Black , and my cinema display is not recognized by my macbook !
And when I bring it to an Aple Store, it worked !
It seems to be a random issue.
I can't find what is the problem...
I tried my cinema display with another macbook and it works.
I tried my Macbook with antoher screen and it worked.
Please help me.

I doubt reinstalling the OS will fix your problem but that's you choice.
FWIW I found the following 6-page thread which may be a similar problem to yours but you will have to search through it for relavance or ideas (I didn't read it):

Horizontal lines on new PowerBook display

Here is my experience with the new PowerBook display/horizontal lines issue. Please post any constructive advice you have that I can try - either to eliminate the problem or to pinpoint the cause more accurately.
I used to own a 15" Powerbook from about 12 months ago, a 1.33GHz model. The display on this was fine. Much better, in terms of brightness and clarity, than my other HP & Dell Windows laptops. When the PowerBook was stolen, one of the main reasons for immediately buying a new replacement PowerBook was the superior display quality.
At the start of November the replacement PowerBook arrived - a 15" hi-res 1.67GHz model. The faint grey horizontal lines covering the whole display were immediately visible. The display is substandard compared to both the previous PowerBook model and my Dell laptop.
Apple Care telephone helpline suggested an NVRAM reset and a PMU reset. Neither of these made any difference.
The PowerBook was then sent back for replacement and a week or so later the new replacement arrived. This also had exactly the same problems.
Apple Care helpline this time said that they could not find any problems with the PowerBook and I should first try the PowerBook connected to an external monitor and secondly take it to an Apple Dealer to show the problem.
I tried it on an external monitor, but unfortunately this is only an old Nokia 15" CRT monitor and though the lines appeared to not be there, the quality of the monitor makes the result inconclusive.
Next up, I will take the PowerBook to the Apple Store. At the same time I have copied "Aqua Blue.bmp" onto my Dell laptop. With the two laptops side by side showing the same image, the defect in the PowerBook display is clearly visible. I hope to be able to take both machines to the Apple Store later this week. I will let the forum know the results...
So, are there any other tips/advice from users as to other tests I can run or other methods to improve the issue?
Many thanks!
It seems obvious, but please don't contravene the Terms of Use for this forum. If you want to complain to Apple, please do it elsewhere - locked posts will get us nowhere

n2o2,
I don't know what let you think that you will eventually receive an AluBook without stripe : Apple Care let you think that ???????.
I have been reading the stripes topics each day since I ordered my new powerbook, late october. I did not see one single post proving that a "free line" 15" powerbook does exist.
The real evidence would come from someone describing the difference between a "non affected" new powerbook sitting besides an affected one, coming from the same PB generation and with exactely the same LCD profile and screen / Colorsync settings.
I did not see a single story like that among the hundred(s) of posts related to horizontal lines.
I have read one post stating that the screen is "crystal clear" and "sharp". The one I received today could be described like that, but it displays those lines, except from the 8 or 10 upper rows of pixels on the menu bar.
The pb15_problems.png file is a very interesting one to me, as it demonstrates that the lines could clearly be attenuated using a single filter without compromising the sharpness/Brightness of the image.
If I compare side by side my 3months old previous generation powerbook and the new one, I must say that (except for the stripes) there is not much difference in daylight in terms of brightness but a perceptible better brightness in the complete darkness.
Well, if someone could prove that some of the new powerbook do not display this "feature", this would certainly push me to return mine. But, seeing how it is difficult to get this organized, I may not want an exchange but a refund, or an upgrade for a 17".
Please tell us quick if you win this battle.

I have an iphone 4s that is having display issues. If I turn the phone on, it vibrates to acknowledge it successfully turned on but the screen stays solid black. I can plug the phone into my computer and itunes will recognize the phone as well.

I have an iphone 4s that is having display issues. If I turn the phone on, it vibrates to acknowledge it successfully turned on but the screen stays solid black. I can plug the phone into my computer and itunes will recognize the phone as well. However, itunes can not do anything with the phone because the phone is locked and I can not unlock the phone because the screen is black.
>CURVEBALL!!!<
The screen does work though! Through trial and error along side a little troubleshooting, I was able to figure out that the screen will cut on after the phone dies completely. The phone has to die completely with no battery power left. Then if I plug the phone into a charge and wait a while for it to charge, the phone will turn on like nothing was ever even wrong with it. I charge the phone up to like 30% and turn it off then bam the phone turns on but the screen is solid black again.
I am currently in the process of waiting for the phone to die and when I turn the phone back on I am going to completely remove the auto-lock and lock code off of the phone for the time being.
Any other suggestions? Please help!

Sounds like the device was dropped at some point and damaged as a result.
Take it to Apple for evaluation and a replacement.

Display issue on brand new 2014 X1 Carbon Touch

So I was about to start raving about my X1C that I just received. Loving the display, the keyboard, build quality, etc. I had no gripes and was just browsing away when suddenly the screen did the full glitch. I recognize this as what happens when something's messed with the motherboard/display adapter. So I gave it a reset. All was normal and then it happened again. I was able to replicate it 3-4 times and it keeps happening. I never dropped it or anything. It was always just stationary.
I can't believe this. I had problems with the first gen non-touch and touch. I was hoping by now they have improved.

Repeated iMac Problems, Display Issues now Kernel Panics

I’m lost on what’s wrong with my 2008 iMac and I think I just have to bring it back into Apple for a third time to have it repaired. But something is obviously not working that is causing these issues.
About a month ago, my computer began showing heavy pixilation, flickering images and the on-screen graphics. The computer appeared to keep working in the background from what I could tell so I came to conclusion that it must be the graphics card that’s failing and I’ll need to have it looked at.
My 2008 iMac was custom-built by Apple with the Nvidia GeForce 8800GS that was offered as an upgrade option. There have been several posts on the display and graphics discussion board about that graphics card along with other postings other places about the problems the Nvidia GeForce 8-series had.
The display problems I mention above would not happen immediately, it would happen as the computer warmed up and was used for 3-5 minutes.
Anyway I brought my computer into Apple explained to them what I believed was the problem and the Apple Store technician agreed with me. Because I did not purchase AppleCare, it cost me $400 and a week without my iMac to have that card replaced.
I got the computer back two weeks ago and everything seemed fine. It was working as it always had. I even was running SMC Fan Control in order to keep the computer as cool as I could (the Nvidia problem was related to overheating).
But this morning, this is what I woke up to:
http://img97.imageshack.us/img97/7436/photoijr.jpg
The computer now has a semi-permanent pixilation when it starts up (as suppose to the pixilation 3-5 minutes into use). But more worrisome now is I cannot start up the computer without it going into a kernel panic. I tried resetting the PRAM, I tried starting in safe mode. The only thing I haven’t tried yet is booting from an external HD which I will try this evening (to hopefully isolate it if it’s hardware or a software problem).
The Apple Hardware Test has been unhelpful. When it originally failed three weeks ago, the test showed nothing and this morning when I ran it (permanent pixilation and all), it showed nothing. I feel like if it was a software issue the pixilation would have disappeared during the hardware test because that’s not an OS-X based program.
Here are my specs on this computer:
2008 iMac 24" 2.8ghz Intel Core Duo, 4 gigs of RAM (Crucial Purchased, I have original sticks somewhere), 1 TB HD, Nvidia GeForce 8800GS.

Hi, just to update you, I came home today and did a few things that didn't seem to solve my Mac's problems:
- I booted up from my firewire "safe" drive that I keep a copy os x on to see if I had a corrupted hard drive or something. It booted into the kernel panic I described above.
- I also swapped out the crucial RAM for Apple's factory RAM. It also booted into the Kernel Panic.
In both incidents, the display issues didn't go away. Now instead of pixelization i have vertical bars running in a pattern across my screen.
I'm currently trying to boot onto the OS X CD at this point to see if I could do a reinstall. It's taking quite awhile to boot into that.
With that in mind, I think we're still having graphics card issues or more seriously some logic board problem.
