PowerPC :: G4 Has White Line Running Through Screen?

Jul 13, 2008

My partner's PowerBook G4 (17-inch 1.67Ghz) which, of course, ended it's Applecare on June 28th, developed a glitch on the screen today: a white line that is 1 pixel wide and runs the length of the screen. It just started out of the blue - no dropping of computer, no power surge, no external reason. One minute it was fine the next it had this line.

Any body ever encounter a problem like this? And if so, how did you get rid of it (either repairing it via a technician or by oneself) and how much did it cost?

I'm betting it's a sign that it's time to get a new computer.

Intel Mac :: Horizontal Lines Float Up Vertically During Video Playback?

May 8, 2012

Recently I have noticed that in certain videos, specifically those that have a lot of movement and blinking lights there is a horizontal line that will appear and float up during playback.  I tried using different media players and the floating line remains.  I have also tried to de-interlace in VLC to no help. I will also add that all of my drivers and software are up to date. 

I'm currently using: 

Version: OSX 10.7.3
Processor: 2.5 GHz Intel Core i5 processor
Graphics: AMD Radeon HD 6750M 512

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.

OS X :: IMac 24" 2006 - Odd Pixelated Line On Screen?

Jan 14, 2010

I have a late 2006 24" IMac which has a myriad of issues. The most concerning to me at this point is the occasional appearance of a 1-2 pixel wide horizontal line which runs from 2" across to sometimes as much as 12" across the screen. It happens most often on the desktop and in firefox. It disappears as mysteriously as it appears.

Could the graphics card be going bad? Any ideas on what might be happening and how I might be able to solve this.

IMac :: Graphical Glitches On The System, Have The Faint Line That Would Run Across The Screen?

Sep 6, 2010

I have an early 2008 Imac with an Nividia 8800 GS graphics card. It apparently failed two weeks ago, and I just got the machine back after the Apple Store replacing the card.The only graphical glitches I had on the Imac, was the faint line that would run across the screen that you could see on a white background if I left a program's window opened to long; and when using Safari, while encoding a dvd, trying to open up a new tab I would get images of whatever I was encoding in the new safari tab for half a second. Then it would correct itself and bring a blank safari page.

PowerPC :: IMac G3 Crt - Loud Short Come From Screen - Quick Line Appear?

Mar 10, 2009

So I've had this computer for a while and about a year or two ago, it started giving me problems. I would hear a loud short come from the screen and then I would see a quick line appear. It started getting worse as the month went on til the whole thing shorted out on me. Now all it does is turn on and shut right off with a loud and pretty frightful shorting sound and won't try to kick back on til an hour or two later (manually anyways). I did some research online and found out that my flyback transformer on my analog board shorted out due to heat constrictions inside the machine. And when that part shortes out, it take sthe video board along with it, since those two board are conjoined together, and in turn takes the whole system out. The wierd part is when I unplug the video cord and turn it on, their are no problems, only that My screen is still off, so it's like flying a plane with no instruments. I heard there is a way to replace the inside parts of the iMac and place a LCD screen in there but I'm not sure how that works out and if it will work anyways. Plus I just read that removing the CRT can be very dangerous. Grrr. I Need some advice. I'm a college student and don't have much $$$. If I did, I would have gotten a new MacBook. I wanna bring this mac back to life cause i miss it. Is there anyway I can do that? What would I need to do?

OS X :: 24" IMac Faint Vertical Line Of Pixels On The Screen?

Mar 12, 2009

i noticed a faint vertical line of pixels on the far left of my screen. they weren't black or colored, just faint/dim. i tried switching my desktop background, and the line was still there. i restarted my computer, and the line was still there. i shut down the computer, thinking that i would find the line there in the morning and have to take it to the apple store.

when i turned the computer on the next morning, there was no line. however, later that evening i noticed a reappearance of the line. i restarted the computer and left for a while. when i came back later, i woke the computer from sleep mode, and the line was gone.

there was no line on the computer this morning, although after a couple hours of use, i noticed that two lines had developed on the edge of where i had application windows open -- in this case, both yahoo messenger for mac. curiously, this didn't happen with other windows (finder, safari, etc).

IMac :: Black Vertical Line Down Left Hand Side Of Screen?

Dec 5, 2010

I've had this iMac about a year now, and i have had this problem for a while but thought i'de leave it for abit and see if it heals its self. As sometimes the line is more visible than other times and sometimes it's not even there!

I have 2 pictures which i snapped with my iPhone, so i will link you too them.

The line is not majorly visible, but it is just annoying considering i payed �1000 for this iMac.

Picture1: Line overlapping my iTunes.


Picture2: Line on boot up.

IMac :: 21.5" Vertical Black Line/Mark Down Left Hand Side Of Screen?

Sep 11, 2010

I have only recently started noticing this, it is mostly visible on the white screen at boot up but just faintly noticed it now against my background.

It is a fading black line going down the left hand side of the screen, it starts at the top kind of fades in the middle then comes out again.

I honestly have no idea what this is, i will try catch a picture on my phone soon and post it up.


UPDATE: Sometimes the line is clear, sometimes it is faint and even sometimes it isn't even there!

Intel Mac :: Screen Goes Black After Startup But Is Still Running?

Jun 19, 2012

I replaced my hard drvie in my A1208 iMac yesterday, and didn't have the OS disc or a  keyboard. After installing the HD, I booted the computer to make sure everything was working. I got the "?" screen, and everything seemend to be working just fine. So today, I picked up a keyboard from the Apple store and dug out the disc After I got back home, I booted the computer to install the OS, and the screen went black a few seconds after the chime and grey screen, but was still running. (I could hear the fan and disc spinning) I've tried to restart, but i'm still having the same problem. I've tried to research other issues, but haven't found anything comparable.

IMac :: Screen Freezing When Fullscreen Video And When Running?

Jan 4, 2011

I purchased a new 27 inch 2.8 imac 2 months ago I'm having problems with the computer/screen going black (sometimes grey with vertical lines) and freezing.

This happens frequently when I'm playing World of Warcraft but has recently started to happen when I'm watching youtube videos in full screen. (Do you think its the graphics card?) I originally ran WOW in bootcamp but I had this problem in Windows as well. The only thing I can do when this happens is force the computer off. This happened so often that something got damaged and I had to reinstall OSX. Since this incident I have not reinstalled Windows via bootcamp.
