Very serious Quad G5 pink pixel display problem!

I've basically had my Quad powered-on for about 30+ hours (the longest yet) and just noticed that a few windows had weird pink pixel artifacts on them over to the left of my display
Basically there's a small area of pink pixels that have appeared over the the left of the screen that draw onto any window that passes over the area. This is definately NOT a problem with my 23" cinema display as they are NOT dead pixels.
These are being generated by the Quad's display output and the only way to get them to disappear is to drag the affected window off-screen and back on.
It's a bit hard to explain so I'll let the pictures do the talking:

I honestly don't think it could get any worse for me at the moment and Apple will most certainly be getting a phone call first thing tomorrow morning (Monday 5th December). You can read-up on my analogue audio line out static problems here http://discussions.apple.com/thread.jspa?threadID=251355&tstart=0

Another update on the problem...
I thought previously that changing the colours from 'millions' to 'thousands' fixed it. It most certainly does NOT! I'm working in 'thousands (colour)' at the moment and just noticed that right in the upper-middle of the screen it's drawing green and yellow pixels in exactly the same mannor as the pink pixels.
It's fairly obvious that my 6600 card is completely screwed!
Just to verify that it isn't a screwed driver problem on my current OS install I booted-up from the Apple system install DVD to see exactly the same pink pixel cluster in exactly the same location upon the installer 'choose' language screen.
Will I have to send the whole Quad G5 back to apple to get a replacement or will they just send me a new card? I have a huge workload here and can't afford to be without my computer. I also need to get this audio static issue fixed (see other thread) but it's completely random and only did it first thing this morining - hasn't done it all day since.

Pink flickering display problem

Hoping someone might be able to help. The screen on my Powerbook G4 15" 1.5Ghz (OS X 10.4.11) is a dark pink (almost black) and flickers. You can still just see the desktop and icons but only very faintly. Originally, it went pink only on start-up (or when the screen woke from sleep) when it would gradually 'warm up' to white. I now can only use it in clamshell mode with a Studio Display which doesn't have the pink problem . From reading other posts, I gather that this seems to suggest that there isn't a problem with the logic board, but maybe the backlight has gone, or a cable, or the inverter needs replacing. Has anyone had the same problem, and if so was one of these that was the problem, and were you able to fix it? I've looked at various online diy repair tutorials and reckon I could handle most of them, but I'd like to be as sure as possible that I'm replacing the rigt parts before undertaking the project. Any suggestions gratefully received.

Peter: I'm sure I wrote a reply to your post the day it first appeared here, but I guess I must have hit the Back button instead of the Post button after composing it. Sorry!
The fact that an external display works fine for you indicates definitively, as you've guessed, that your logic board (including the GPU) is working properly. The problem is with your display backlight. An old, tired fluorescent backlight tube is typically pink or reddish until it warms up, and a very old one may stay pink or reddish all the time. If your backlight is flickering, it may never warm up properly, so that may explain its continued pinkness. The flickering may be caused by a failing inverter (which supplies power to the backlight) or by a damaged backlight cable (damage can be caused by chafing where the cable passes through the display hinge) or, much less likely, by a failing backlight tube. In your shoes, I would begin by replacing the inverter to see whether that eliminates the flickering. Replacing either the cable or the backlight tube is much more involved, and I don't recommend those as DIY procedures.
Sarah: You haven't told us how your display is misbehaving, so I don't know whether or not my advice to Peter is on target for you too. Exactly what are you seeing on your built-in display, and what do you see when you connect an external display?

Intel Mac Mini Pink hue display problem

Originally purchase a refurbed Mac Mini 1.66 Intel Core Duo, and over the years I've upgraded the RAM (w/ 2 Gigs) replace wifi "G" card with "N" card. Unfortunately, my mac mini died. Went to the Apple store in Tampa, and the genius said the logic board was toast.
I replaced the logic board with 1.83GHz Intel Core Duo board, and everything is working fine except for the display.
When it starts up, the standard grey screen now has a pink hue. After booting is finished the screen still has the pink hue. However, after a bit, the screen turns to normal, but there is some flicker. My mini is connected to a Samsung LCD 17" display that is working fine. There are no cable issues, I connected the display to my iBook, and it works fine.
Has anyone come across this before? Do I need to reseat the RAM sticks? Is there a software setting that I need to change since I upgraded from a 1.66 logic board to a 1.83?
The logic board is under warranty, but I was hoping to get some answers that can be easily fixed instead of sending it back.

I took the mac mini to work, and hooked it up to my monitor. It still displayed the pink hue at start up. I'm leaning toward this being a bad logic board.
One thing that is curious is that the screen will loose most of the pink hue as the Mac Mini warms up. It's almost back to normal, but the colors still have a little too much pink even after adjusting the monitor. Also, you can see flicker as it warms up as well.
I'm sending back the logic board for replacement.

Serious display problem. Please help!

I'm having a serious display problem all of a sudden. It is not application specific. Various different applications are pixelating, especially wherever I move my cursor and click the mouse. When I grab the entire application with the cursor and move it, the image duplicates into hundreds of images all over my screen. If I shake it around awhile, eventually it goes back to normal. What is going on??!!
Here's some background info: I'm on a 2009 Mac Pro. I still use the old fashioned tube monitors with mini display port to VGA converters, but I've never had a problem up until now. Just before the problem started happening, I tried to open up some .jpg files in Quicktime Pro 7.
I would greatly appreciate any ideas of what the problem could be and how to fix it.

Very serious system wide problem

I am having a very serious problem. It started today, after I installed the kernel extension for iStat, so I think that might be it. I have uninstalled that, but the problem persists. After about thirty minutes of uptime, everything will stop working properly. Disk images won't mount. When I open up Terminal it says "Command complete". Applications don't open at all. My account loses admin privileges, even though it says I have them in System Preferences. System Preferences doesn't work properly. My weather widget says "NaN" instead of a temperature. If I restart it works, but I can't do that every 30 minutes. Does anyone have any advice on how to fix this? It is rather urgent.

If you are on a Windows network and sharing your Mac with the Windows machines you run the risk of the samba demon running wild. If you aren't on a network go to System Prefs and turn off Windows and Printer sharing. If you are on a network and need to leave that function on, go to the Discussions home page and do a Search on "smbd"--you'll find lots of things to read.

HP G72 display problems...sometimes very grainy...and sometimes no display at all.

Display is grainy sometimes with a blue tint. Most of the time it will not come on at all. When an External monitor is hooked up it looks and works great. Display problem itself or video card problem??

Hello , Thank you for visiting the HP Forums! A great place where you can find solutions for your issues, with help from the community! I came across your issue about the display, and wanted to help! If the notebook is working on the external monitor, then perhaps the display cable in your notebook is loose, or needs to be reconnected. If you are comfortable with the process, you can take the notebook apart, to check if the display cable is properly secure. You can use the following document to assist you, if needed:HP G72 Notebook PC - Maintenance and Service Guide (Chapter 4, Page 69-70). Here is an additional document, that may be helpful: HP Notebook PCs - Troubleshooting a Notebook LCD Panel Issue (Windows 8/8.1, 7) If you are not comfortable with that process, then you may consider contacting HP Phone Support for additional options.

External Cinema Display Problem

Hi,
so I have my new MacBook connected to an "old" 20" Cinema Display using the MiniDisplay port and a MiniDisplay to DVI adapter. It has been working just fine since I connected it a couple of days ago.
I have the MacBook lid closed and I am using just the external display at home.
Today I left my room for an hour or so. After coming back and waking the computer from sleep I was horrified seeing my display full of weird artifacts, randomly displayed blue and pink pixels. On top of that the display was turning off and on (going black) every couple of seconds.
I don't know if it's a problem with:
a) the MacBook
b) the display
c) the connection (adapter?)
Any ideas? Anyone experienced a similar issue?
Best greetings,
Tomasz

I talked to Apple tech support today. After initial description of the problem and basic troubleshooting, I was referred to a product specialist. She had me do an SMC reset (shut down, disconnect power cord and all external devices, remove batter, hold power button for 10 seconds, reinstall battery, connect power and start) which seemed to clear up the problem. But it returned later in the day. I called them back and was immediately sent to the product specialist again. The next step is to take it to the Apple Store to have it looked at there. I won't be able to do that for at least another 10 days, so there won't be any more progress on this problem until then.
When I talked to tech support, they had no information on any such problem in their database, which means they haven't heard it from anyone but me. So if you're having this problem, please call tech support and tell them about it. If they start getting lots of reports, then it starts to look like a real problem and not just one guy who might be doing any number of things to make this happen. Apple tech support has been very good those very few times I have had to talk to them. If you are referred to a product specialist, you might have to wait 10 minutes, but it's worth the wait. You're talking to people you can understand who can answer your questions - they're not reading off of a script. You get a case number so that if you have to call back, you can pick up where you left off - you're not stuck explaining everything all over again.

Ideacentre B320 display problem

I'm suffering from a display problem, and cannot figure if it's a software or hardware issue... I'm on Win7 64bit. Here are the symptoms:
1) For a while now, intermittently the screen would go grey (or some sort of a messed up pattern of rgb pixels) and I would have to power down forcefully. The frequency of this has gone up very much in the recent weeks
2) When the machine freezes, I can still hear the music playing, and Windows continues to do whatever it was doing before
3) Recently (I'm guessing after a Windows update), I wasn't able to boot into normal mode anymore. It would show the Windows splash screen, then before the login screen appears it would just go black and freeze. Leaving it for a long time doesn't lead to recovery
4) To try and fix this, I've updated the ATI driver to the latest version, which didn't work so progressively tried every version between the11.6 and 10.3 (4?) which was the default when the machine was purchased. No luck there. I've also flashed the bios and that didn't help either
5) I can boot into safe mode, so I disabled amdkmdap using sysinternal's autoruns.exe, which meant that I can boot into normal mode, but it woud fall back onto Windows' vga driver (1400x1050 only!)
6) Now, even in the low res mode, almost daily the grey screen freezing would happen and I would have to reboot. Tapping the power button allows the shutdown dialog to come up (I'm guessing), and pressing enter would shut down the machine then.
There's an awful lot of posts on the internet regarding people having issues with ATI HD6450 and similar category cards, some of which sound similar to my case. They too experienced the freezing problem and reverting or upgrading the drivers had no effect (many even reinstalled windows completely). It sounds like though, the problem is software in origin at a guess.
On the other hand, the machine is now 3-4 years old and I could imagine that the GPU or graphics memory might have suffered wear and tear -- emailing Lenovo support took a week to get a response, the only thing they asked was whether my warranty is still active (after that it's been a complete silence) are they usually this terrible?
The last thing is, when the problem first occurred I booted using a linux live CD and it was all fine, at full resolution graphics. I haven't repeated this experiment since it takes quite a while to boot from a CD... but suggested that the hardware is intact. In fact, by messing about with the drivers I was able to boot into Windows normal mode and operate for 1-2 days, after which the grey freeze happened again. I haven't been able to get back into that since.
Here is my question: Is there a way to find out whether it's software or hardware that's at fault? If it turns out to be hardware, what are my options at replacements? The GPU is soldered onto the motherboard, so do I have to replace the whole thing? If it's a software issue, would restoring to factory default state fix this issue, given that an unknown update could cause the same issue at any time... This is the last time I will buy an AIO without removable everything.

Welcome to the Lenovo Community !
Probably a good test of the hardware is use the Linux Live CD that you used earlier. If the graphics are still good when using the Live CD then your monitor and GPU are fine.
If the hardware checks out Ok then I suspect you have a driver problem. Try using a driver cleaner to fully uninstall the ATI driver since bit and pieces left over from previous driver installs can cause problems. The link below is for a free and highly recommended utility for cleaning the system of the graphic drivers. After the clean up I would try installing the original driver that came with your system.

Vertical Pink pixel line 17-inch, Early 2011 MacbookPro

For the past week my MBP has been acting up. When I irk on 2-3 programs simultaenously ,the screen gets distorted and I am forced to press and hold the power button to reset.
Today there is a permanent pink pixel line on my display.
Is there any workaround solution or anyway to switch off the AMD graphics card ? I believe thats the culprit.
I have a 17 inch early 2011 2.2 Ghz Intel Core i& with 4GB DDR3 RAM on OSX 10.9.4
Model

I see an impressive collection of LaunchAgents, Launch Daemons, Internet Plugins and drivers for who knows what. At this point I would like to suggest a completely clean install of your system (after making a complete backup of course).
At the very least uninstall the Kaspersky software completely, and the same with what remains of the terrible CleanMyMac software.

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.

S.U.
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

My original post, locked by this forum. Display problem related

Hi G5 Gurus,
The display problem first, we all know when screen savers display, a click on the mouse will bring you back to the active desktop, this was how it worked., but now, sometimes a click cause the G5 to sleep!
As for the sleep, I dare not to put it to sleep these days, because I am afriad it may cause a fire by over heating. Sometmes, actually four times in the past few months, my G5 could wake up by itself, followed by a extrem high speed running of the cooling fan, it sounded like a hair dryer running in the same room. Sometimes the sreen could light up, just like real wake up, sometimes, it was black. No clicks the mouse or keyboeard could bring it back to normal, I had to press and hold the power button to turn it off.
This crazy problem happened for the first time last summer, a dead hard disk was the cost. Apple replaced it, but failed to detect the cooling or power or display problem. I was given one month extended free service, but right after its end, the problem was back and happened even more often.
Please let me know if any of you had the same problem and please advise what to do.
100s Gs of thanks.

I have the EXACT same problem. In fact, I could not have described it better myself. What gives? I brought it in to the "genius" bar and they repolaced the power supply free of charge but the problem is still there. I noticed they ordered a new logic board but did not end up replacing it after all. Did you have yours replaced and did it work? Is this a known issue?

Hi La teller,
Thank you for your reply. The 'genius' here in London only replace the dead hard disk, which I belive was a victim of this problem. I was told they couldn't find anything wrong with the power supply or the cooling system.
Now at lest I know I am not the only bad luck guy. Let's wait and see if others are having the same problem. I am not sure if this is a known issue to Apple, even if it is, it may take years before they can offer a recall or free repaire. I noticed that some G5s have already been suffering from power problems and a free repaire was offered.
Thank you again and hope Apple can take our concerns into their consideration soon.

Hello,
I'm also having this problem (fan running, won't come out of sleep), just spoke with an apple care rep. He confirmed my suspition that it was software, not hardware as I have just had the logic board and power supply replaced.
His suggestions were to:
1. Run disk repair from the startup CD
try running OS X from a firewire drive and see if the same behavior happens or
perform and archive and install.
When the fan starts to run like that it means the OS is not communicating with the hardware properly. The OS could be somewhat corrupt if you were having hardware issues beforehand, hence the need for a reinstall. I will be performing an archive and install after the disk repair, I'll let you know if it fixes the problem!

Hi Stopha6,
Thank you for your message. I never imagined it could be a software issue, cos it looked so hardware.
Please keep me updated with your progress.
By the way, as I said in my old posts, a hard disk went dead when this happened for the very first time, how do you read this?
Thank you.

Hi Stopha6,
After reading your reply again, I realized that the system had already been reinstalled. As I said when it happened for the first time, the hard disk died with it, which was replaced, of course with a new OS X, but the same problem is still happening. May this suggest that it is not just a software problem? Thank you. Songyan

The Fans going at full is only because you have an application that is using a lot of cpu power and therefore causing the imac to heat up so it turns the fans on. The screen-saver and sleep problem you describe sounds like something that may just happen on accident. But this sounds mostly like a software problem. Try making sure to always quit all non-apple products and see if anything changes.

Thank you, Ag-Nate. I will try as you adivised but I con't think the fans were activeted my intensive CPU using. In most of the cases, the problems happened when the Mac was sleeping, when the minimum CPU were being used.

"The Fans going at full is only because you have an application that is using a lot of cpu power and therefore causing the imac to heat up so it turns the fans on."
That's only partly right. A hard-working process will make the fans run at high speed, of course.
But, the OS is in touch with the firmware of the iMac, telling it how to run the fans, based upon information the OS X kernel is getting about the state of the hardware.
If the firmware loses touch with the OS for some reason, and is not getting instructions on how to run the fan, it will default to running them at full blast, to be on the safe side (and this "full blast" fan mode is way louder than anything you'll generally experience during normal usage, I know from experience).
So it may not be so simple as a hard-working cpu process kicking the fans on.

Hi I have a 20" G5 imac it's about 18 months old and I am having the same problem, It freezes and the fan runs really loud. It's nothing to do with software as my I.T. guy has done a complete re-install. All of our admin people have imacs of differring ages and the flat panels are all OK but every one of the G5s has had a booting problem. Some fell into the recall for replacement logic boards but the one I have at home is the newest and doesn't. I'm waiting for my apple reseller to get back to me, but it looks like it's the logic board and as none of the serial numbers fall into the recall, I'm expecting a big bill. I'm really disappointed as I've been a professional apple user for over 15 years and have grown to expect a certain amount of honesty and integrity from them. Looking at all of the discussion boards and the amount of people complaining of the same problem the logic boards are defective and apple should be replacing these free of charge.

Kensall,
Welcome to Apple Discussions!
As in the other thread I wrote:
Being from England, you may find the repair program under these pages:
http://www.apple.com/uk/support/imac/repairextensionprogram/
http://www.apple.com/uk/support/imac/powersupply/repairextension/
Check both of them as they refer to different models.
If neither of yours is under the program, please start a new topic thread so someone can help you.
http://discussions.apple.com/forum.jspa?forumID=881
First off, you'll get a wider audience who may be able to solve your problem. Secondly, responses to you won't confuse the original poster with solutions that don't apply to them. And thirdly, you'll know for certain whether or not a response applies to you.

I am having a very similar problem. My G5 imac has already had the logic board replaced from the leaking capacitor problem. 8 mos. later the power supply was replaced under the second recall program when it failed to start up.
It had been working now for almost a year, when about 3 mos. ago I started to experience the sudden dimming effect - if the display was untouched the screen would dim about 30% similar to a laptop in energy save mode. I checked and none of these types of options were set in the pref panes. At the same time I would have the iMac go to sleep after a while from non-use, and then when I tried to wake it it would stir for a few seconds and then go right back to sleep. It took 2-3 attempts to wake it up.
Then last week, as I tried to wake it, it just shut down instead completely. I had to hold the power button down to recycle it to get it to come back to life (3 times).
Today was it - I found what I thought was a sleeping iMac, but it will not power up at all. I opened the back cover and the power supply is working, but I cannot get the board to energize, I reset the PMU, but the #2 LED won't even blink. It is completely dead.
Basically every time I used this computer I held my breath that it would not work. After 2 recalls I still only get 9 mos. out of it? Apple is really starting to show it is like the "big" computer makers, the quality is going right down the tubes.

Display Problem with my Mac Pro and LG Flatron Wide Monitor in Mountain Lion

After upgrading to Mountain Lion, my Mac Pro has display problems with my LG Flatron display. The image is displayed with a black bar on the right and on the bottom. And the left side of the content is not visible. I tried every resolution available in the Display System Preferences, they are different in terms of how big the black bars are, and what part is not visible, but none of them are correct. I held down the option key to try to detect displays or switch to resolutions that are not normally available. When I restart the image is lined up with the display, but if the display ever goes to sleep or gets turned off, the image reverts to being off center, and the only way I can get it back is to restart... The interesting thing is that this monitor works fine with the same machine if I reboot using BootCamp into Windows 7. The Monitor also works fine, connecting the same connector to a Mac Mini, although that mac mini is running 10.6 and not Mountain Lion. I've reset the SMC and restarted countless times, I don't see any other levers to pull or things to try...

That card is for a PC it may not give you Startup and Option-Boot screens.
The 7950 "Mac Edition" card has a very distinctive look:

Windows 7 64 bit on iMac display problems and instability

I received my iMac 27" quad core with 8 gig ram & 2 x 1 TB hard drives last Friday. I'm using Boot Camp to run windows 7 64 bit on maximum 2560 x 1440 screen resolution.
I get intermittent but often display problems in windows 7. I get areas of the screen covered in little yellow dots or blue squares (never red artefacts.) This will happen at random areas of the screen, inside an open window, around borders of windows and so on. Most often the screen will go black and come back with a message in the bottom right corner of the screen saying 'Display driver has stopped responding and has recovered' with the sub message saying 'display driver ATI radeon family stopped....etc'. Sometimes I lose the screen wallpaper. Once I've had the system just shut down, once I've had Photoshop seize up and I had to do a cold reboot. Could this be an overheating problem or resolution too high problem or driver problem? Windows 7 tells me my drivers are up to date. I tried installing the drivers for the card from ATI's website which made no difference
The reason I bought a Mac is because it's the only effective way to code for the Mac family of OS's in XCode. The reason I didn't just attach a miniMac to my PC monitor was because there's rather a lot of advertising by Apple about the fact that you can use a Mac with a PC OS via Apple's own Boot Camp. Now I have a lot of Windows software (some of which is not available for the Mac or requires buying again) sitting on an unstable system. Any ideas would be much appreciated...

Sorry, that thread got moved for edit and as a user tip... which I didn't want and won't be doing....
Here is the post:
A tip and workaround for how to get ATI mobility/laptop drivers so that Windows no longer thinks the ATI is a desktop card:
http://discussions.apple.com/thread.jspa?messageID=11286987
Summary (my own edit steps):
1. Install Boot Camp 3.0 and upgrade to 3.1
2. Uninstall graphic drivers and run Driver Sweeper
http://www.guru3d.com/category/driversweeper/
instead of:
removing the crashing driver by going into windows 7 setup via its install cd and deleting the ati driver manaully
3. Install ATI Mobility (link)
4. Uninstall ATI (Programs control panel?) Device Manager (rollback; uninstall?)
5. Device Nanager: update driver and BROWSE BACK to 8.681 (the original apple driver that was causing freezes and purple artifacts) - navigate to /Apple/Drivers/ATI
(Apple uses) a 4850 card in the iMac, its modified a bit for apple. Enough that desktop drivers don't work, and modded-for-laptop desktop drivers don't work either.
Now the upshot of using modified drivers is that it FORCES the catalyst control panel to be installed, meaning you get a few more options to mess around with the card.
I couldn't use the original apple drive, it locks up, the newer one had banding, the newer radeon drivers direct form ATI wouldn't work until they were modded and then they cause black screens.
SO the solution, as obscure as it was, was to download ACTUAL mobility Radeon drivers - version 10.3 still, but made for laptops.
http://support.amd.com/us/gpudownload/Pages/index.aspx
THESE drivers I was able to install - and here is where things changed.
THIS driver changed they way windows saw the video card in device manager.
As I mentioned before, its NOT a desktop card, its a modified laptop card, but installing mac drivers makes windows THINK its a full desktop card, and running the original 8.681 driver crashed it.
Once installed 10.3 LAPTOP driver it now appeared in device manager as a MOBILITY card.
+These Steps "should" work:+
delete ATI driver manually
reinstall apple driver after that and see if that works,
otherwise try the steps above
(mod drivers, remove via windows recovery off setup disk, install laptop drivers, reinstall apple driver over it)

Display problem in macbook pro 13

I have been facing a display problem in my macbook pro (mid 2010, 13 inch) for more than six month. I talked to many persons from applecare and conformed to their advice. but the problem remains same. I went to apple authorised service provider at least 8 times. they changed my logic board, RAM etc. the problem remains same.
finally, I talked to applecare again. they adviced me to run fresh Lion installation and observe the machine without any thridd party software. I got the same problem.
when I call them, every person attending the call advices me new thing ! they are very polite and say: "if you have this problem again, please inform me." unfortunately, when I write them again about the same problem they do not care it !!!
I am very much frustated and psychologically tired with this issue.
Thanks a lot for your assistance.

I can only do wild guesses at this popint, only thing I can think of on your end is possible AC power problems, but I've not been impressed with Apple's quality since the 68K or Beige days.
THe iMac7,1 I'm on now needed repair 3 times & still scares me with it's PSU temps.

Very serious Quad G5 pink pixel display problem!
