Display issues, maybe?

My brother has an iMac G5 that recently hasn't been turning on when he tries to boot it up. He got it used from the library, and I don't know how old it is except that it probably is at least over a year, maybe 2? Any help would be greatly appreciated.

Just to tell you my story...
I bought a Macbook black in Mexico late 2007. not a week passed and the left shift key broke... that's ok.. I'm under warranty. I took it back and what they said amazed me. Keys on the keyboard are not on warranty! SAY WHAT????
yep.. Went to all Apple stores, Service centers, you name it.. the same answer.
Then I traveled to the states and went to the Small Dogs in Vermont, the apple distributor in that state. first thing they ask is do you have a warranty still? Yep! So leave it here and come back tomorrow.
AMAZING!!! free of charge, spanish keyboard and all!!! they changed everything!
Couldn't keep the old one though because it was done under warranty.
Thankfully nothing more happened to this lovely laptop!!!

Display issues on mid 2009 Macbook Pro

I have had a recent intermittent display issue on my Macbook pro. It started a few months ago and is not a constant issue. External displays are fine so it seems to point to a connection between grahpics card and the 13" screen.
You can see an image of the problem here:
Does anyone have experience of similar issues?

i've done a complete rebuild back to 10.6.8 and found that both problems appear to have disappeared, both screen and TV working again since this morning without seeing any issues.
I'm now installing Lion to see if it returns.
the only difference will be that I'm not going to install bootcamp until later, this will be a clean install as before I installed Lion on a previous version of 10.6.8 with bootcamp etc already installed.
maybe this will work, wish me luck

Display issue: green, flashing pixels, low resolution on my new MBP 17"

I just bought my MacBook Pro 17" on December 2010 from Authorized Reseller in Dublin.
After couple of days for the first time and now every 2-3 days my MBP's display goes suddenly pixleated with green, shiny pixels and all display appears like low resolution. After closing the lid and opening it again the problem disappears. During that display problem my computer has no issue with performance like: video playing, opening and closing applications, rebooting, etc. Here are some screen shots made by my photo camera during this display issue: http://img132.imageshack.us/img132/809/dsc03872j.jpg http://img64.imageshack.us/img64/6670/dsc03879x.jpg http://img834.imageshack.us/img834/7914/dsc03885z.jpg http://img23.imageshack.us/img23/3830/dsc03881g.jpg
I should mention that I also made a screen shot with Shiftcmd3 combination of keys during this display issue and it appears, as you can see http://img521.imageshack.us/img521/8618/screenshot20110123at204.png as it should be - sharp and clear. One of my friend said that maybe I should reinstall operating system, but my guess is that it isn't software (Snow Leopard) issue. By the way, I have all the latest updates.
Please, can you tell me what is the problem, what is causing it and what should I do?
Thank you.

Ok, guys, I should update my main post about screen issues on my MacBook Pro 17" 2010 model, because it was quiet a big issue. It was actually problem not with display panel (which was completely replaced and which didn't resolved that screen issue at all) but with motherboard which has been replaced (by Mactivate).
After almost 3 months I can say that the computer had no issues since the repair: no screen issues, no noisy running vents.
I must say I am happy with repair made by Mactivate (actually one of few repair services authorized and recommended by Apple). They arranged the pick up with their own currier with no charge, great communication and most of all - they did everything to resolve this quiet unusual issue with my display.
I really and honestly can recommend Mactivate to anyone in Ireland.

10.5.3 Update display issue. None of the already discussed...

I've calibrated my display at a colour management facility some weeks ago, and took a screen picture of the brightness setting in system preferences... so that i could recall it in case i changed the brightness by accident.
well, after updating couple days ago, i was asked to restart my computer. i did restart, but the computer acted weirdly, taking a lot of time installing extra stuff and eventually auto-restarting extra 2 times before showing my desktop again.
once it did, i noticed right away my screen was a little darker and maybe with lesss contrast. I checked Display preferences (Adjuts display brightness left Uncheked) and with the brightness slider at the same point as usual, it was significantly darker. Actually, i need almost full brightness to get the same white that was 70% brightness before the update.
I see a lot of people with display issues after that update, what is going on?
ps: i'm using 2008 LED 15" MBP

That extra stuff your computer was installing may have been things that Software Update downloaded automatically but didn't install at the time. Don't worry, restarting twice is normal. By chance did you notice a drop in brightness after the update when running on battery power? When you unplug a MacBook Pro, the screen automatically dims a bit to save energy.

IPhone 3g baterry bar display issue?

Well, I recently got a replacement for my 3g, and ever since then, the battery bar is acting up. The problem that Im experiencing is that the battery is going from being fully charged, to loosing around 1/10 of the battery display within maybe 5 minutes of me taking it of the charger...
< Important>
I know it's a display issue and not an acutal bettery problem, Since it gets the same use and still gets me through the day, and gets the same ammount if use.
<\importance>
I did a Fresh restore this morning and nothing, still the same issue, I'm going to recalibrate the battery today after school, but want some Tips or something to try out in the case that it doesn't work... If not, back to the apple store for a third time In a week lol...

I am having a similar problem here, the bar acts funny but when it reaches 60% it stays allot longer, tho it can decrease from 100% to 90% just like that when I remove it from recharge

Output display issue in only a particular user account.

Let me start off by noting that I recently switched to mac from windows. Last night I was browsing around the system just getting a feel for the environment when the color / display changed and looked something like a display one would see from booting up in safe mode on a windows machine. I went on to restart and log back into the user account where I was having the display issue, but that did not work. I ran the tech tool deluxe suite to try and find the problem, maybe the video ram? That test came back with no issues to report. I went into the administrator account and found that the display there was normal, and then checked the problem account once more to find that my problem was not solved. Luckily I did not have a lot of information on the problem account so I went onto delete the problem account and recreated a new one. This solved my display issues. Does anyone have any idea why this would have happened or what I can do to prevent it from happening? Should I contact Apple because I am not sure if this may be a hardware/software issue/defect? Thanks.

If you open the Universal Access pane in System Preferences and select "White on Black" in the Seeing tab does that replicate the problem? I'm not familiar with Safe mode on a Windows machine.

Interlacing problem - display issue or something else?

Hi, another interlacing question...
So I captured my footage (originally shot on film, telecined to digibeta) at 10 bit uncompressed to do my online (the offline edit was a 29.97 DVCam dub of that digibeta). Since I'm finishing on 29.97 digibeta, I didn't remove the pulldown as I captured offline or online, and am editing both at my finishing medium's frame rate. So yes, I have the duped fields in there, but it also keeps things simple and I've theoretically been seeing exactly what the finished version will look like the whole time.
Last time I did this workflow I used a G4 running a dual 867 processor with a gig of RAM, and I had some jitter and interlacing "comb" visible when I watched the 10-bit on the Mac, but when I output to digibeta and DVD, it looked fine. So it appeared to be that my computer simply didn't have the juice to display it properly, but that the media itself was fine, as were both ways of outputting.
Now I have a spankin' new Mac Pro with a quad 2.66G processor and 3Gigs of RAM, so I figured that "display issue" was behind me. But not only do I still see jitter and comb on my computer monitor, I also see it much worse on the test DVD I just made. So the problem isn't just the display. The look is very similar to when you capture a clip and remove the pulldown, but fail to start capture on an A frame (but since this is all 29.97, I know that isn't the problem).
I thought it might be that the drives were not fast enough, so I reformatted two of my internal drives into a Raid 0 and put the media there and reconnected it. The raid seems happy, and it's less than half full, but the video doesn't look any better.
Any idea what else could be causing this? I did just upgrade the project from the FCP 4.5 version I started to the FCP 6 on the new machine, plus my experience has been that moving from offline DV to online can allow in some bugs, but the ins/outs, clip names, frame rates, haven't changed. And of course I've been editnig 29.97 DV this whole time without seeing any of the interlacing on the monitor or tyhe outputs. Could field dominance have anything to do with this? I've never adjusted that in previous applications of this workflow, so it doesn't seem relevant, but I confess I'm not sure what I'm messing with there. Do I need still more RAM? The computers we ran at school a couple of years ago were running 10 bit video on G5s without significant upgrades to my knowledge, and this is just a single stream with a few tracks of audio here. I'm afraid to spend any more $$ until I'm pretty confident it'll solve the problem (shoestring budget here of course). Any thoughts?
Many thanks.

Thanks for the reply. I don't really have a way to hook up my computer to a broadcast monitor. I know I should, but can't really afford the card to do it. So I color corrected my footage carefully during telecine, and for things like this issue, I'm making DVDs quick and dirty through iDVD, then watching them on my home TV (an LCD that plays both SD and HD).
I suppose something in my DVD player and/or TV might be giving me the weirdness in the display, but I think I mentioned I did this same workflow before on a lowly G4, and back then while the computer display showed the interlacing problems, the final output looks fine on the same TV/DVD setup I'm using now. (And I also output that timeline on the previous project to a digibeta master and it looked great too--unfortunately no way to test that digibeta output on the present project without going to a post house, which of course cuts into the budget.)
Maybe I need to bite the bullet and stop being so cheap, but I'm hung up on the fact that it worked fine before, and I can't see how this stronger computer is performing comparatively poorly.
BTW I do see the interlacing in FCP viewer and canvas, but only when it's set to 100% size. And it looks identical in Quicktime as well.
The other thought that just occurred to me is that it might be a codec issue. Perhaps the uncompressed 10 bit codec on my new machine isn't quite the same 10 bit uncompressed as the Kona card used to capture the video for both new and old projects. Maybe my old computer worked ok because that codec was slightly different, or I may have even copied the codec to that computer at some point in the past.
Any of this spur any other ideas? Again I really appreciate the help...

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.

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.

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.

Bizarre & Random Dashboards Display Issues/Errors

Hello,
I am on BI 4.1 SP04 and these dashboards were developed using an equivalent level on the client tool. (4.1 SP04)
Sometimes we get very strange and often random display issues with our dashboards. I have attached screen shots for examples. Sometime we are missing data points from rendering on the charts, other times a line chart will extend into a bar chart. Has anyone experienced this or have any idea what could cause this? It is very frustrating...
Thanks for looking,
Gary
Missing data points on yellow line, yet line rendering with proper data (other wise would have 0's in places, etc)
Green line missing dot on last end point
In this example there are no dots on the yellow line or green line
In this example the blue line has turned into massive columns extending across the charts

This patch should resolve the issue in the last screenshot. I still face the other issues after upgrading to SP3 Patch 4. The dots in line chart take some time to appear. Also, if we use dynamic visibility, the components taking considerable time to appear sometimes. I hope this will also be fixed in later patches. Please share your experience too after applying the patch.

Multi User Calendar Display Issue

When we moved to GW2012 one of our departments that uses a Multi User calendar (5 users in total) noticed some strange display issues.
When User1 is looking at her Multi User Calendar, the client is displaying her appointments in User2's column as well. But if you look at User2's Multi User calendar, you don't see any of User1's appointments in User2's column, so it appears to be a display issue with User1. This same issue is happening with one other user.
All users are on Client 12.0.2, Build 108211 . Interestingly if we look at the calendar on a machine running the GW8 client this display issue does not occur. I have also gone as far as rebuilding the calendar from scratch but this hasn't changed anything.
Any suggestions?
Thanks!
Steve

Hi
If you open a Service Request with Novell Technical Services you will receive this Field Test File patch for the GroupWise 2012 Client. It is specifically to fix issues with multi-user calenders. Please let us know if you are in a position to open an SR.
Many thanks.

MacBook Pro Startup and Display Issues

I've been having some random problems with my MacBook Pro (2.16 GHz, 2 GB RAM, 100 GB 7200 rpm hard drive, ATI Radeon X1600 graphics). Specifically:
1. Lines across the screen and purple boxes sometimes appear.
2. The graphic effects (e.g. zooming a window) sometimes get "frozen" on the screen. In other words a remnant from the animation will stay until the window is refreshed.
3. The Mac sometimes freezes during the startup process. Sometimes the login screen will be unresponsive and other times the Mac will almost bootup but fail when loading startup items.
4. Less frequently the Mac will freeze randomly. I previously had iStat Menus installed and each time the MacBook Pro froze up it indicated both read and write disk activities.
Yesterday I decided to wipe the machine clean and start from scratch in case there were a software issue or corruption on the hard drive that was causing my woes. I completely erased my hard drive and even zeroed the entire disk to make sure everything was completely wiped out. I also disconnected all peripherals to simplify things as much as possible.
The first time I tried the reinstall everything completed successfully but the "Welcome" movie froze part way through. I then had problems running the install again. I was able to boot off the Leopard DVD, but the machine froze a couple of clicks into the install procedure. After numerous tries I was able to erase the hard drive once again and install Leopard. This completed successfully and I installed all updates.
The problems started to show up again almost immediately, however. I installed iLife and iWork and all the updates and had the computer freeze up on me again during a reboot. I also noticed that the display issues started to show up again even before installing any third-party software.
I've tried running disk tests with Drive Genius 2.1, but no errors have been reported. I've also used the freeware Rember program to run memory tests but have yet to see any errors. Sometimes my Mac powers up without any problems and once it's powered up it often stays running for days. The display issues appear quite frequently. I've using iStat Menus to keep an eye on the temperature sensors and everything appears to be normal - so it doesn't appear to be temperature related.
Fortunately the computer's still covered under the extended AppleCare warranty, but I would like to have some idea what's going on before I take it in just in case they're not able to reproduce the issues.
Any suggestions and insights would be GREATLY appreciated. Thanks in advance for reading my rather long-winded message.
Cheers,
Tim

I took my MacBook Pro in for repair and it turned out to be an issue with the logic board. I had the logic board replaced (fortunately it was covered under my extended AppleCare warranty) and these problems are a thing of the past.

13" Macbook (black), Snow Leopard, Boot Camp, Windows 7 display issue

OK I don't know where to post this. I couldn't find an appropriate forum under Boot Camp (nothing for display). Apologies if this is the wrong forum.
I am attempting to run Windows 7 using Boot Camp. Here is the behavior:
Booting Windows 7 without any monitor plugged in works fine.
Booting with an external monitor plugged in, I get the display on the external monitor. Now when I unplug the external monitor, the LCD display backlight is off and is completely dim. I had to reboot it in order for the LCD display to work again.
This is not a macbook display issue. But it has to do something with the way Windows 7, BootCamp are compatible with a macbook. Anyone seen this or know what the fix is?
Thanks
Sri

I can not get my Win 7 (32) os to see my Mac 10.6 partition. Is there something I need to set or turn on to get this to work?
As for your problem, perhaps Windows is not seeing the FireWire bus?

Display issues, maybe?
