Dead Pixel Lines Across My iMac G5

Hello. PLEASE HELP I don't know how to attach pictures here to show you what this looks like, but its about 12 inches across of non conforming pixels. One near the top of the screen middle, then two more lower middle half about the same in length. They go away sometimes, after a reboot, or when I change users. But they are there no matter which background I have up. AND also now it seem like there are problems with the same image distortion crap when I am using Safari.
PLEASE help. Is there anything I can do? or is this a hardware issue for sure.
I know the computer is not that new, but any type of warranty for this stuff?
Let me know if you have seen this happen, AND if you'd like to see pics to diagnose, let me know I can send them along.
THANKS!
Frustrated in NY.

  • Pixelated Line Across iMac screen, occasional...

    My iMac is 4.5 years old and works great except for a pesky horizontal pixelated line across the screen. I have seen it towards to the top, and now lately, it's moved instead toward the bottom of the screen.  It will usually 'attach' itself to a particular open window, not necessarily to my Desktop. It happens with a Browser windown, or an email, or any application, really.
    Is this a sign of anything other than age of the machine? Does this indicate trouble I don't realize?
    I have had this issue for months. It's occasional and more of an annoyance than anything disruptive to me.

    These appear on all windows I open.  I took a screen shot using grab and the very definite gray line doesn't appear.
    Excellent work, the Screen Grab grabs it from the Video card, so the prlem is after/outside of that.
    Could be the Internal Video cable, or the LCD itself.

  • I am having problems with video and high content webpages freezing.  I am also getting pixel lines across my webpages.  Maybe two or three lines.  I was running os 10.4 but I just up graded to 10.6 the other day.  I have 2GB of RAM.

    Exactlly which model iMac do you have?
    see > How to identify iMac models
    Unfortunately that is not all that uncommon for the Early Intel iMac's given there age and the fact that the air intakes are probably choked with dust. Then add the extra heat caused by running a more intense OS X which is causing it to run a little warmer than normal and putting extra stress on the graphic and display components.
    My 6½ year old 17" Early 2006 Core Duo w/2GB of RAM is also running 10.6.8 and is also starting to get a single line that (knock on wood) goes away after a few minutes, while many others started getting permanent ones after 2 or 3 years. One thing that I think has helped, is that about every 3 or 4 months I shutdown and vigorously vacuum out the bottom grill work and small vent under the stand to keep it running cool.
    On that note: unfortunately I can only suggest that you clean your intake vents and hope that no permanent or irreversible damage has been done.

  • Red line across screen imac

    i just bought a iMac 21,5" (2012) for 7 days.
    and i found a red line across the iMac screen sometimes.
    no problem found from the diagnostic mode.
    any other method for me to check the problem?
    or can i have a product return or refund, but not repair for this case?
    i will be very disappointed, if there is any QC issue for apple product.

  • HT2807 why is there a horizontal line across my imac screen?

    why is there a horizontal line across my imac screen?

    Not sure exactly which model your iMac is..?
    see > How to identify iMac models
    Sadly display lines generally indicate a problem with either the Display or the Graphic's Chip.
    To check, take a screen shot of the display using the (Command Shift 3) keys and open it.
    If the line is only seen on the Display and not in a screen shot, then it would most likely indicate a Display problem.
    If the line shows up in a screen shot, then it would most likely indicate a Graphic's Ciip problem.

  • Dead pixel in 17 inch iMac.

    I just got my iMac G5 yesterday, and it really is the greatest computer ever, but I noticed that there's a dead pixel on my otherwise perfect screen. It's an extremely small white dot (smaller than a grain of salt), which is hardly noticeable, but it still bothers me when I do see it. It's borderline nitpicking, but I did pay good money for this thing. Does my warranty cover this?

    At the Apple Store here in Las Vegas, I was looking at discounted iMacs a while back. G4s. They had two for a decent discount. One was a demo model, the other one was a return with 1 dead pixel. Otherwise, it was brand new. They were willing to sell it for $200 less, but after two weeks no one was buying. I asked what happened, if the original purchaser got a new one, and the rep told me they replaced the whole computer for free (he was the rep that did the transaction). He also told me the guy was there for about two hours filling out paperwork. Also, the whole thing had transpired three weeks before I was there, and they still hadn't sold the computer, just because of that one dead pixel.
    The dead pixel was a red one in the bottom-right corner, about two inches from the side and one inch from the bottom.
    I guess the guy was lucky?

  • Pixel line across screen

    My laptop sudden has a pixel line running fully across the screen from the left of the screen to the right. I have rebooted, updated drivers, used pixel repair software and tried to rub the pixels clear. which makes me believe its possibly a hardware issue. Has anyone else con across this problem or know what could be wrong?

    Contact HP in your region. It may be hardware display issue.
    Have a look at this:

  • Extreme amount of dead pixels on 24" 2006 iMac intel

    Currently I am in possession of an iMac Core 2 Duo model A1200 (24"), which has severe display problems. There are dead pixels all over the screen, and even when in text mode the same problems occur, but distorting the text characters. This is OS-Independent, as it happens on every OS I have tried on it. In addition to that, sometimes CDs/DVDs don't show any display when they boot, however the dead pixels are still there. I've tried swapping the original RAM with new RAM of same make/speed/capacity, and the same glitches still happen. The RAM I swapped in is known to be good, as it has gone through 7 passes of Memtest86 with no errors. The only two things I could possibly narrow it down to are the Optical Drive or the HDD. The HDD is failing (according to the OSX install disc Disk Utility), but that should not affect the display. I checked the internal display cable and it shows no signs of a break. I have tried resetting the PRAM, which did nothing to fix it.
    Example of display problems (shown while running memtest): http://img812.imageshack.us/img812/8060/imacfaildisplay.jpg
    Any help would be appreciated.

    +However, the apple page does not seem to accept my serial number for some reason+
    I would assume that it doesn't accept it because you are past your warranty period. You can still take it to an AASP for an estimate and/or repair.
    As for the Apple Hardware test, it does not necessarily pick up 100% of all hardware problems, so it is not the "absolute" test to rely on. Did you run the extended test?

  • Pixelated lines across images from the web module in LR

    I use Lightroom 5.2 and am having problems when exporting via the Web module. When I use the basic LR HTML template or plug-ins like Juicebox and TTG, there are pixelted lines acorss some (but not all) of the images. This has started to happen in the last few weeks. Any thoughts/suggestions?

    Here's my guess ... somehow the file has gotten corrupted.
    I can't tell you exactly what step it got corrupted at ... you'll have to do the research ... it could be that it is corrupt on your hard disk, and Lightroom is attempting to use a corrupted photo; or it could be when Lightroom exports via the Web Module the file is saved in correupted form (most likely cause is a bad hard disk); or it could get corrupted in the upload; or it could be corrupted on the hard disk on the server (bad hard disk again).

  • Single pixel white line across macbook pro retina screen

    I have a Mid-2012 model of the Macbook Pro 15inch with Retina screen which is just out of 1 year warentee. 
    There has suddenly appeared a very thin white (pixelated) line across my screen - about 1/3 way down from the top.
    Its constantly there, but more visible on a grey background.
    I've contacted Mac about it and they say since its out of warentee they can't help!
    Its literally 14months old... almost seems like the issue is perfectly timed to happen just out of warentee!
    I'd be keen to hear if others have experienced similar problems with the retina screen or have found any solutions!

  • Iphone 4 screen/display - 1 pixel line problem

    Hi,
    I have a cca. 1 month old iPhone 4 from New Zealand Apple Store.
    There is a cca 1 pixel bright line across the screen/display and a smaller one next to it. These seem like dead pixel lines.
    Sometimes it is hard to see the lines, sometimes are very bright - I think it depends on the color of the background.
    I realized that problem aproximately 4-5 days after I received the new iPhone. .
    My problem is, that few days after I got my new iPhone I traveled to Europe. Now I am in Hungary and I will go back to NZ in October.
    I could not find any on-line contact for NZ Apple... finally I went to Hungarian Apple Service to ask them about my problem, but they said they cannot help.
    I have Apple Care Protection plan as well. Can I get a replacement, or ... ?
    I do not know what to do, where to go, who can help me...
    Can somebody tell me who do I need to contact?
    Thanks
    Monika

    Hello, Harmeet Singh. 
    Thank you for visiting Apple Support Communities.
    Here are the best troubleshooting resources to reference when experiencing this issue.

    Display has no backlight or dark screen
    Toggle the ringer switch to see if the unit vibrates. If it does, it could be that iPhone is getting power, but is not displaying any image.
    Try turning iPhone off and then on again.
    While connected to the iPhone charger, try to reset the iPhone.
    If the low-battery screen appears, charge the iPhone.

  • Ipod touch 4th gen dead pixels

    Replacing the screen may work but it could be a problem with the logic board

  • Horizontal line across 23" Cinema Display

    Hi
    I am using a friend's display, and it has an annoying horizontal 1 pixel line across the screen about 40% of the way down from the top. This is the 23" aluminum Cinema Display with the external power brick and DVI connector. The pixels appear to be about 50% gray, but the color changes a little (to a dark gray) depending on the surrounding image being displayed.
    Any thoughts about what might be causing this and if there might be an inexpensive fix? (FWIW, I know it is in the screen since it does the same thing w/ various laptops plugged in.)
    TIA
    A

    I had that happen on my 30" ACD. I believe it was caused by a power surge, but could've been just crappy manufacturing. Suffice to say I had display replaced (luckily it happened during the first 30 days).
    I hope you have AppleCare for your display so that it can get replaced/fixed.

  • 17" iMac intermittant line of dead pixels

    Bought a new 4th gen 17" imac on Aug 13. Aug 15, new imac has horizontal line of "dead" pixels 1/3 of the way from top of screen that goes right across. I say "dead", as they are not truly dead pixels, they are just not displaying correctly. This is a problem that only seems to occur when I wake the computer or the monitor from sleep. It will stay like this for a while, and then it will eventually disappear. The only solution I have found so far is restarting the computer (pain in the butt), but this also seems to fix it self every now and again by pulling up the dashboard or by other random actions (I would rather deal with this ANY DAY over dealing with Vista or any other PC for that matter).
    Before going through the ordeal of taking my computer back to Future Shop (Canada's Best Buy) and getting them to look at it (I will be without computer for weeks) has anyone ever experienced this, and do you know of a permanent solution?
    On a side note, sometimes (but only sometimes) when this occurs, my dock also will not unhide when I mouse over. I know how to fix that issue, but perhaps these issues are related.

    I have a similar problem but my line is not intermittant but is here to stay.

  • 24" iMac Thin darker line on the screen - dead pixels ?

    I have a 24" BTO iMac with 3,06 and GE Force 8800 GS, delivered last year in June.
    Was very happy until today, when i remarked, at +/- 7 cms from the right edge, a thin line, extending from top to bottom, and seeming to expand a bit in a blurry way in the middle.
    It shows much more in when on a dark background.
    Could that be dead pixels ?
    I guess I have to ship the machine back to an ARC ?
    Or is there some test I could try first ?

    A screenshot would not including any effect from a physical screen defect. For the computer, the pixels are there and working properly.
    If it appears to be blurry, it may be something casting a shadow between the LCD and the backlighting. Dead pixels are distinct, so there should not be a blur between where the pixels are working and where they are not working.
    In any case, since the Mac is still covered by the one-year warranty, you should probably have it looked at by an Apple authorized repair place
