PowerPC :: Powerbook Display (horizontal Line)

Oct 16, 2008

when I woke my pbook up the screen had a horizontal line across it, and below that there is doubling and tripling of the screen image going on. Rebooting didn't accomplish anything and when I take a screenshot it doesn't show up there. I have a 12" Powerbook G4, running os 10.4.11.

Nov 27, 2009

I have a Powerbook G4, and noticed a line (a thickness of a hairline) on my monitor displayed horizontally, about a length of 1/16 of an inch.

MacBook Pro :: Horizontal Line In Display?

Jun 21, 2010

i've got a little problem with my Mac Book Pro.

I have a white line in the display where I also have my dock. So it's not always on the same Display. You can see a few pictures attached that show you that this line is some kind of weird. Windows that are always in the front like "About my Mac" are over this line and if I open all windows of one program I get three of those lines.

The lines are here since I updated my MacBook to the newest firmware.

MacBook Pro :: Horizontal Line Appearing On Retina Display

Sep 5, 2014

i recently bought a 13"retina display macbook pro. It is so disappointing. There is a horizontal line that appears on the screen and disappears. This was for the third time i had to face the same issue. When i explain to the staff at the apple store they say that they have not come across such issue, for which i showed a proof from the other part of the world.

PowerPC :: Powerbook Internal Display Won't Turn On With External Display

May 22, 2007

For the past few months i have been using an external display hooked up to my 12" powerbook g4. I have had it on a dual display mode so no mirroring. Recently i would open the laptop lid waking it from being in sleep mode and my internal display will not turn on. The apply system profiler does not even recognize that the internal display exists. My external display works fine and has always been set as the main display. If i go to detect displays nothign happens. I have tried restarting the computer, instering system disks, unplugging the external and nothing has worked. I simply cannot get my internal screen to fire back up. When i used to unplug my external display the internal display would switch back to being the main display and everything would be fine. Now i cannot get the internal display to function whatsoever. Please try and help me as a need this laptop working and i will be ordering a mac pro soon for use with my external display.

MacBook Pro :: Horizontal Line Across The Screen?

Sep 27, 2009

I have a new MacBook Pro (A1286) 2.66Ghz which is just over two weeks old. Whilst watching a video on YouTube a horizontal line appeared across the screen. I tried rebooting, however, the line was still present. I have tried switching between the 9400/9600 and the line is still visible.

The line is still there when I boot the laptop into Windows, does it look like I have a faulty GPU/logicboard on my brand new MacBook?

Here's a photo of the problem.

OS X :: Dot Mark And Tiny Horizontal Line On Screen

Jul 6, 2010

I've just noticed two small marks in the lower right-hand corner of my iMac's screen: a tiny horizontal line to the right of a dot. I can see them when I restart the computer, but not when the wallpaper is on the screen. Clear Screen won't remove them, but they don't seem to be scratches either, partly because I can't feel them. Do you think they're dust specks or something like them tat somehow got behind the screen? I hope there's a safe way to remove them because I hate to see them.

Intel Mac :: Horizontal Gray Line Across Screen?

May 21, 2012

This evening, quite suddenly, a gray (or black, depending on what's on the screen) vertical line has appeared across my imac screen, about a quarter of the way up from the bottom.  Above that are some are three, much lighter lines (more like subtle variations or blocks of colour running across the screen). These appear on all windows I open.  I took a screen shot using grab and the very definite gray line doesn't appear.

MacBook Pro :: Horizontal Line In Full Screen Mode?

MacBook Air ::5 Dead Pixels In The Center And The Horizontal Line Options

Nov 20, 2008

Anyone think this is a good deal? http://www.amazon.com/Apple-MacBook-MB003LL-Laptop-Processor/dp/B0006HU4DK/ref=pd_bbs_sr_1?ie=UTF8&s=electronics&qid=1227225131&sr=8-1. I bought the Rev B, but had to return it because of 5 dead pixels in the center and the horizontal line issue. I am thinking of saving over $1,000 by getting the above. It is new/in box and from amazon. This is the best deal I have seen. It is even cheaper than the refurb models at apple.com.

PowerPC :: Powerbook G4 Display - Serial # Does Not Fall Within The Ones Specified

Apr 13, 2007

I am currently experiencing the issues displayed here... http://www.apple.com/support/powerbook/displayprogram/

However my serial # does not fall within the ones specified. My powerbook was purchased in early Sept of 2004, and I have applecare so it will be up in Sept of 2007.

I am unsure of what I should do at this time and am looking for recomendations of how to handle the situation. I am aware that apple will probably try to say that is it somehow my fault and that i put too much pressure on the lid of the powerbook (as this happened to a friend of mine, and she was actually within the serial #'s that were specified in the link above)

I have kept my powerbook extremely protected (at one point I even had it in a neoprene sleeve inside of a hard sided zip case!) and really don't think it's anything i've done, or wear and tear on the notebook (it's in near mint condition other than a few spots just below the arrow and command keys.)

PowerPC :: 23" ACD Won't Display When Connecting To Powerbook?

Mar 5, 2008

I just bought a 23" ACD and I'm having trouble getting it to work with my 17" Powerbook. I checked it in the store before buying and it worked fine, but at home it's not responding. The display is recognised in Preferences and is giving me a choice of resolutions, the light is on, but I can't get the screen to show anything. I've tried adjusting the brightness to bring up an image to no avail, turning mirroring on, and closing the lid on the Powerbook then waking it again but nothing gives me an image on the 23".

My Powerbook is a 1GHz 17" with a GeForce4 MX 64 MB.

PowerPC :: Won't Hook Up / Using Apple LED Cinema Display With PowerBook G4

PowerPC :: Display Won't Fill Screen After Replacement On Powerbook G4

Jan 3, 2010

I just bought a Powerbook G4 off of Clist. The previous owner replaced the screen with a higher resolution screen from a newer Powerbook. The display looks great, except that it doesn't fill the whole screen. There is a long group of colored lines on the right side, and the bottom starts to show the top of the display (it looks almost tiled and shows the screen again on the bottom). I'm guessing that this is just a formatting issue, but I'm not sure how to correct it.

PowerPC :: Display Error When Hooking Up Powerbook To External Monitor?

Mar 7, 2009

irst off, according to mac tracker the Powerbook I have is the Powerbook G4 15 inch FW-800. I am running Mac OS X Leopard 10.5.6

Alright. About one week ago, I hooked up the powerbook to a 19 inch external LCD monitor with a DVI to VGA convertor, and all was well. It found my supported resolution and everything, worked straight away, etc.

Fast forward to today, at about 2pm (4 hours ago) I was using the computer and everything was working fine, but I had left it on for a few days so I shut it off when I was about to take a nap. I wake up from said nap about 20 minutes ago, turn on my Mac and my external display is only showing up at 800x600. I have no idea how this could have happened. This would not be an issue if my monitor's native resolution of 1440x900 were on the massive list of resolutions to chose from, but alas it is not.

PowerPC :: PowerBook G4 12" Alum 1GHz Display/resetting Pram And Pmu?

Sep 3, 2009

I've recently purchased a broken 1GHz Alum PowerBook G4 12", and the display isn't working. I have a total of two 12" PowerBook displays, and I've tested both. They've worked perfectly fine. Then I've tried reseting the PMU and PRAM, no luck, but they've attempted to work. Tried the Mini-DVI to VGA adapter with my display, still no luck. The keyboard, optical drive, and hard drive works as if it was booting, and there was always a clear chime, even when I've reset the PRAM and PMU (the beep sound when PRAM also attempted). I've inserted a Leopard install disk, and it sounded like it was working perfectly fine. Hopefully it's not a motherboard issue

Mac Pro :: Green Horizontal Lines On Display And Crashing

Aug 31, 2014

I have a 2007 Mac Pro 1,1 with attached 24" apple display and utilizing 5 GB Ram and maxed out on internal hard drives. It's been a flawless workhorse and I mostly tax it with Photoshop which it does well. Well, yesterday, I was viewing a small video on my Mac when this issue occurred. Suddenly I saw these squiggly looking horizontal lines on my display. Then I saw a spinning beach ball. I had to shut down.

I double checked my display cables in case any were loose - no issues. Restarted without issue. Went back to work on my computer - no issues doing ordinary tasks such as opening windows, moving files and surfing the internet. Went back into Photoshop and resized several dozen images without issue. Then, this happened again... restarted. Zapped PRAM just in case. Fired up Tech Tool Deluxe (older version 3.1.3) and it found NO problems, I passed all tests. 

Then... out of nowhere it crashed again, third time... I don't recall what I was doing to be honest. I shut down my Mac last night and this morning have spent an hour on and so far, so good. However, I'm not taxing it by doing anything intense. I need to use Photoshop for a project I'm working on so I will do that soon and see if this issue repeats. 

I've tried searching the forums but can't find anything conclusive to my specific issue. What else should I do? What else should I check? Is this hardware or a software issue? I have temperature monitor installed - should I be looking at specific temperature increases and if so, where? 

GPU going bad on logic board? This is a really close up image taken with my iphone, obviously the lines aren't this large.

Software :: Flashing Horizontal Flicker On EMac Display

Aug 25, 2008

I have an EMac G4 that has a number of problems, It is a 1.25gz. Sometimes it will boot to a blue, blank screen, on holding down the alt key I see the boot drive and I can start up (10.4os) but will go to the blue screen again. When it does start up properly, which it does for no apparent reason, there are little dash shaped spots on the screen and a flashing horizontal flicker. I ran fsck and disk utility and installed a fresh version of 10.4 to no avail. I do not have the original disks so cannot run hardware test. The computer falls under the Apple emac screen repair but they will not accept it because it is out of the three year time limit, very frustrating and unfair.

Software :: Video Display Is All Blue With Horizontal Lines?

Jan 1, 2010

My iMac boots up (OSX 10.4) and when the desktop is about to appear the little spinning wheel start to get "fuzzy" (yes only the wheel), then when it's time for the desktop to appear the entire screen goes blue with horizontal lines across it. I can see nothing on the screen at all except that mess.

Weird thing is, if I boot using the install disc, everything is fine. he display never screws up. So I am guessing some file or something is corrupted in OSX?

I was going to do a restore, but since there have been some updates since I got it, I am worried about that whole process and not being able to get to my pictures and what not on the HD. The procedure where I can archive the current OS and reinstall the original seems like my next step.

IMac :: Horizontal Lines Showing Constantly On 24" Display

Jan 27, 2009

I have a 2.8GHz Intel Core 2 Duo 24 inch iMac in may-june 2008. I bought it because I wanted to avoid the 20 inch display problems. Somehow I feel I ended up with the wrong side of the deal. Check the snapshot please:
The picture was taken using my iPhone so it's not exacty Cannon quality, but still, it describes my problem in 1000 words

What would you do in my place. Would you risk getting another one, maybe a crappier one? It is ludicrous that you take part in a russian lottery when buying a fairly expensive product like a Mac.

MacBook Pro :: Beeps And Horizontal Bars In Display Of 201113"

Mar 13, 2012

I'm running 8GB RAM as I have been for several months now. I typically run several apps at a time for days at a time rarely dipping below 1GB available. When I do I use the Free Memory app to free up RAM.  

Minutes ago I left my MBP for a couple minutes to do something across the room. It began making single short beeps spaced a couple seconds apart. When I ran over to check out what was going on I noticed the display had 2-3 vertical stripes through it each containing dozens of horizontal colored bars. The beeps continued without stopping. The display was unusable for the duration. I could not tell if th keyboard or trackpad were responding so I chose ot reboot.  

After reboot it seemed fine and reopened all of the apps that had been running previously. Or is this a sign of specific hardware beginning to fail?

MacBook Pro :: Display Is Frequently Horizontal Gray Lines Going Across Screen

Jul 1, 2014

my MacBook pro display that there are frequently horizontal grey lines going across my screen. I've noticed it mostly when the display color should be grey or white, but that's not always the case. It occurs mostly in my Google search bar using Firefox, and also occurs heavily on Facebook in the comments/reply section of a post. Outside of the browser I've also seen it when looking through some personal photos, especially of the sky, the lines will seem to sort of outline different contrasts in white or light tones, kind of like the Magic Wand tool would do in Photoshop. The lines do flicker and change when scrolling.I attempted to snap a photo with my iPhone the best I could. 

My specs:

-13" Macbook Pro (2009)
-Intel Core 2 Duo 2.26 GHz
-NVIDIA GeForce 9400M
-Resolution: 1280x800, 32-bit Color

PowerPC :: Powerbook Battery - Significance Of Levels For Powerbook G4 15''

I am leaving for a week long trip and many parts of it will not be able to run the computer off of the powercord, which is a problem because I get about 40mins of wordprocessing use out of it when I run the battery alone. Can someone explain what the significance of these levels are for my Powerbook G4 15'' (Alm) 1.25GHz, namely the cycle count and full charge/remaining capacity?
