Hardware :: Pink Flashing Columns On Screen?

Aug 9, 2009

I was wondering if anyone might know anything about the pink flashing columns i'm experiencing on my iMac screen. at first, there was one column on the screen with pink stripes... the second time it continued the same, and the third time, another column of pink stripes opened up and it really started distorting the image on the desktop, moving up and down uncontrollably.

MacBook Pro :: Pink And Green Vertical Pixel Columns On Screen?

Sep 2, 2010

My A1226 is really giving me fits. It will display persistent vertical pink and green pixel column patterns in windows or over the entire screen at start up. I have twice performed the "PRAM Re-set" with Command-Option-P-R depressed with pwer on and that has worked. But tonight it came back and I had to do it a third time. Is this a potential or probable power/battery problem? I hope someone here is familiar with this!

MacBook Pro :: Screen Goes Pink By Itself?

Mar 19, 2012

My late 2009 Macbook Pro started to have screen issues a couple weeks ago. Basically, the screen just goes pink as in the picture below. The laptop came with a dual GPU (GeForce 9400M & GeForce 9600M GT) and switching between them does not resolve the problem. I also tried re-calibrating the screen display, but to no avail. I tried googling the issue but nothing useful came out of that. I've also tried running the apple hardware test but it said everything is fine. 

This issue has come out of nowhere (I haven't spilled anything on my laptop, nor have I dropped it...). At first, it appeared to go pink randomly, and go back to normal randomly. But now, it remains pink all the time. I would have taken it to an Apple Store if I could, unfortunately there's no such thing as an Apple Store in my country.So now I'm stuck with this annoying pink screen

PowerPC :: Screen Goes Pink Flickering On IBook

Apr 2, 2010

I'm new to this forum and sensed that maybe someone could give me an advice about my damaged LCD screen of my old iBook.

A few days ago I opened my iBook and the screen suddenly couldn't portrait any white color properly. Everything was flickering and moving. Darker areas have a green flickering as well. I'm not a absolute tech expert, but I tried already a few things. I hooked it up to an external monitor and the picture was fine! So it must be hardware related right?

Now the weird thing. Sometimes the panel suddenly works properly for a few hours. I don't know what could trigger it, I tried everything. What should I do? I took some pictures and uploaded them to Flickr:

I know the machine is old, but I originally planned to get a new MBP this summer. I can't afford a new machine right now and the current MBP are just overpriced compared to similar old products on the market.
I have to be mobile, so I need a laptop.

MacBook Pro :: Frozen Screen With Pink/Blue Lines?

Sep 3, 2010

My almost 3 year old MBP shows a full screen of artifacts like horizontal lines with blue and pink boxes. It did it while simply browsing the web. It had a message in the center of the screen that said to push the power button to power off in several languages.

I powered off the computer. Tried to restart it and on the start up screen the Apple appears in the center of the screen with the same pink and blue boxes in it and the spinning symbol below is stuck and the computer will not start up.

Any ideas on what my problem is? I have about 2 months of Apple Care left.

MacBook Pro :: Frozen Screen With Pink And Green Pixels

Aug 27, 2014

I have an early 2008 version of the 17" MacBook Pro. During the process of uploading photos to iPhoto, the screen froze and pink and green pixels appeared. I shut down by the off button and upon on turning it back on found the screen as shown below. The apple appears and then the clock spins for a moment then freezes. I cannot get any further. 

I've tried booting in Safe Mode and other options I've read when trying to boot but to no avail. 

Someone said I need to run the AHT but as this was purchased from a friend, I don't have the installation CD's. I've found a DMG file of the AHT but am completely at a loss as to what to do with this.

MacBook :: Screen Suddenly Shows Blue And Pink Vertical Lines?

Apr 25, 2012

I am trying to get my MacBook LCD to work right. It happened because one time I was carefully wiping my MacBook screen with a little hand sanitizer and a paper towel. However, later my screen started to show a-lot of weird lines and eventually blue, pink and green tiny vertical lines but it is not completely renderd useless, it is just plain annoying and whenever I have an open window on the screen for a long time and I move it around eventually, it shows an imprint in the background into the screen and even when I restart, shutdown or use Windows in BootCamp it just shows up.

MacBook :: Getting Rid Of Vertical Black Columns On Computer Screen / When It Is Connected To Projector

Aug 26, 2014

My macbook is running Mavericks OS X 10.9.4, and I'm having difficulty getting rid of the vertical black columns on my computer screen when it is connected to my classroom projector.  I've played with the resolutions, and the best resolution for the VGA display is 1024x768...Unfortunately this creates less than desirable black columns on my computer screen.  Another teacher in my school has display settings of "1024x768 stretched," and her macbook does not have the issue mine does.  However, I don't think she is running Mavericks 10.9.4.  I cannot find this display option on my computer.

OS X V10.7 Lion :: Screen Keeps Flashing As Though A Screen Capture Was Being Made?

Jun 21, 2012

This is unnerving. At random intervals, my screen flashes. It more like "winks" - as though a screen capture was being made. Actually, when you make a real screen capture, the screen doesn't wink, but that's the impression I get. The screen doesn't flicker or flash like it's a hardware bad connection, but goes through a fast, but continuous normal-white-normal cycle. I'm looking at my activity monitor to see if something is unusual, but I can't tell. Everything I look up seems to be real.

Mac Pro :: Screen Flashing And Freezing?

Apr 6, 2012

I have a 2008 Mac Pro, which has served me well since I got it, at least until a day or two ago. At that time, it started exhibiting sporadic black flickering on screen, paired with freezing. At first, everything would freeze except the audio, which would continue playing uninterrupted, and after a minute or so the system would unfreeze like nothing happened. Now, though, it seems to have gotten worse; the system doesn't seem to recover after a flickering episode, and even the audio will get stuck into a one second loop after a while. 

I tried resetting the PRAM and the SMC. When that didn't work, I tried restarting into Lion Recovery mode with Command-R. For some reason, that sent me right to a reinstall screen, but it didn't matter, because the screen started flickering and the system froze almost immediately after startup. I'm pretty sure that what it froze in was a separate recovery partition, so that should rule out any software issue. I'm guessing that my video card is fried, but I'd like to see what others think; I'd like to avoid buying a video card that I don't need.

MacBook Pro :: Random Flashing Screen?

Jun 11, 2010

My screen periodically starts flashing and getting huge white lines that run down the screen when I play games (only have crysis maximum edition) but then it stops and goes back to normal. Ive noticed that it doesnt happen all the time, and not at certain moments in the game (i.e. happens at one point but doesnt happen again at that same point a different time) and it will stop if i go and look only at a wall. Is this normal or is my MBP F'd?

Hardware :: Flashing Question Mark On Screen?

Jun 29, 2009

2.0GHz MacBook running 10.5. My friend's computer which he brought to me thinking I might be able to get it booted.

My buddy went to bed last night, running a video on his hard drive with the computer hooked up to his flat screen TV, he fell asleep while it was playing. This morning he woke up to a frozen screen. He did a manual shutdown. Upon restart he got a gray screen with nothing showing.

I have tried the original installation disk and restart while holding down "C" with no result.

I tried a copy of Tech Tools 5 in the DVD drive... with no result.

I have tried booting off of my own external firewire HD upon which I keep a bootable clone of os10.4.11... with no result.

I tried booting off that same external HD while holding down "C" and got the flashing folder with question mark.

I tried using a firewire cable and starting the bad macbook in target mode while hooked up to my old iBook. This caused the macbook screen to show a firewire symbol and nothing showed up on my iBook screen but an archive... Tech Tools on my iBook recognized the archive but could not Unmount the archive when I tried to use any of the tools to explore or fix the target disk.

I know that the flashing question mark indicates there is no start up software to be found, but I have to question whether this might not be something more than a bad HD. Anyone have any suggestions?

BTW... the macbook is out of warranty. My friend just went ahead and ordered a new macbook pro so there is no pressing need to get this fixed in a hurry, but he would like to get the old computer fixed if it is just a matter of replacing an HD.

PowerPC :: Wine + Ibook = Flashing Screen?

Well, a friend of mine spilled wine on my ibook g4. Other than trying to decide how much if not all of it to ask her to pay(my wine, but on an armrest and I was in the other room), I was wondering if anyone can fix suggestions. We got the battery out and it unplugged right away, but when I turn it on the screen violently flashes on and off. It does seem to run fine other than that, though.

MacBook Pro :: Light Blue Screen Flashing?

Aug 18, 2008

When shutting down, we get a familiar light blue screen before the computer turns off. I'm getting this flashing at me while operating my MBP. It seems to happen twice, every so often. The screen will turn blue and become empty simultaneously for about a half second - then the screen I'm expecting to see comes back for about half a second - and then the light blue screen comes back again for about a half a second, and then everything goes back to normal.What the heck is this?

I must say, I'm having a little bit of a difficult time with my switch to Apple from Microsoft last November. I've already had to replace the logic board, it appears as if my network card is no longer working (I can only connect via WiFi) - and now I'm having this odd light-blue screen flashing... My video card?

OS X :: Black Screen With A Flashing White Line?

Aug 8, 2009

I have an iMac 2.8 24 inch, about Two years old running 10.5.7 , when I start the computer it shows the normal Gray screen for about 30 seconds, then the screen goes all Black , but with a small flashing white line ( _ ) in the top Left hand side corner.

It just stays all Black for ever , I then hold down the On / Off button and turn off the computer, I then hold down the keyboard '' option key '' and press the on button at the same time , then I get the option to start from the main HDD , I click the Icon and the computer then starts normally , and every thing runs ok.

Can some one please tell me what I have to do to get my iMac to start up normally again , Ive run Repair Disk permissions but the problem still occurs . Over the last few day's Ive been trying out a few new applications, so not too sure if this has any thing to do with this current problem
