PowerPC :: Strange Pink Artifacts Over IMac G5 Screen

May 11, 2009

I have an iMac G5 (rev. B with ambient light sensor) which has suddenly started having a problem where the entire screen is covered with pink artifacts. The iMac had been left on overnight and when waking up in the morning I found the screen looking like this and now it continues to stay like this no matter what I do. I have attached a screenshot and was wondering if anyone might have a clue what has caused this to happen

Hardware :: Strange Screen Artifacts - Red Vertical Lines

Oct 25, 2008

I was using Audacity on my mac running 10.4.11, on some seriously large files (85MB mp3s were exported from these original wav files!), when during this these red vertical lines started popping up on my screen; mainly where a window had been moved. These lines haven't gone away and I'm not sure how to fix this problem. I'm stumped! Having repaired permissions and run the Disk Utility from the Install disk, I'm at a total loss. The intro/gray screen, apple logo doesn't have the red lines, but every other screen does.

PowerPC :: IMac G4 Screen - Violent Pink Tint On It?

Aug 6, 2009

I have a 15'' iMac G4 with 800 MHZ processor and 768 mb ram. I woke it from sleep one day when suddenly everything had a violent pink tint to it. I had no idea what to do. I've replugged-in the video cable, messed with Colorsync, blew dust from the internal monitor port. I don't know what to do!!

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.

IMac :: Random Artifacts / Glitches On The Screen?

Sep 15, 2010

I've had my 27" iMac (3.06GHz) for a few weeks now and yesterday I noticed some weird artifacts appearing on the screen, very randomly.

They will pop up all over the screen but if I "Show desktop", they will go away for a bit but sometimes reappear again in different areas of the screen. I restarted the computer but that only temporarily fixed the problem.

Anyone know what's causing this and how to fix it?

IMac :: Pink / White And Green Checked Pattern On Screen

Mar 15, 2010

I own a 17" g5 imac and today I was just browsing on Firefox and all of a sudden the screen became checkered with thin pink and white lines. It is most noticeable on the menu bar and anything that is grey or white in color. It is not checkered on the blue background behind my desktop photo. I have an external monitor plugged in as well and the same thing is happening to that monitor.

I have a powerPC imac G5
OSX 10.5.8
ATI Radeon 9600

Here is a screen shot:
Haven't reformatted it yet. Hope there is a better solution. Purchased it used about a year ago. No warranty.

PowerPC :: Strange Powerbook Monitor Dimming Screen?

Sep 1, 2006

I'm experiencing a problem with my monitor on my 1.67 GHz PowerPC G4 recently. A few weeks ago the monitor would dim when extended past parallel. Now It dims past 30 degrees. It seems to be getting worse by the day. Anybody have any ideas why this is happening, and more importantly; how to fix it? By the way, I don't know much about the insides of these things.

PowerPC :: IMac G5 Strange Vertical Lines Of Squares?

Nov 2, 2008

I have a problem with the display of an iMac G5 20". It shows up as vertical lines of small squares.

If I change screen resolution, the display will look ok for about half a second, and then it comes back again. Anyone had seen this before? (This is does not look like the usual problem with iMac and thin vertical lines.)

OS X :: Screen Artifacts While Using Safari

Sep 18, 2009

Hopefully somebody can tell me what's wrong. because it's getting basically impossible for me to do anything on 3 year old MBP. These are artifacts show up mostly when I use Safari. In fact when I CTRL T for a new a tab that's when it's the worst. But it happens when I'm using Photoshop sometimes and other programs. but anyway it seems to be getting worse.

Software :: OS Crash With Screen Artifacts

Mar 7, 2010

I'm gonna apologize in advance if this was already posted, but I'm not quite sure what the technical phrasing for this issue is, so I could've missed it in search. I'm running a Macbook Pro 17', manufactured around September 08. It's currently running OS X 10.5. I received it from my school with the computer already set up and all the software pre-installed, so I personally don't have access to things like the boot disc and other base software, but I can get a hold of it if it's necessary. The crash: Somewhere along the boot-up process, or somewhere soon after boot-up, the computer will freeze and a bunch of pixels will rearange themselves. I wish I could show a screenshot, but the best way I can describe it is that these little jagged stripes of pixels will move to places they aren't supposed to; for example, below the little spinning boot-up circle on the initial boot screen, there's a block of pixels kind of shaped like --.--_ that pulses darker and lighter in time with the pixels on the bottom of the circle, so they just seem to be transposed from another position on the screen. If this happens during boot-up, which is most of the time (on the screen with the dark grey apple on a light grey background), then the computer will try to boot up for a while, then the artifacts will run in stripes down the screen and a window will come up telling me to restart my computer. Sometimes--usually when I've shut it down and taken out the battery and let it sit for a while--it'll get past boot-up, and I'll get either almost to the desktop or even get a couple minutes of actual use before the artifacts appear again and the computer freezes.,......

PowerPC :: 15" Display Pink On Warm Up?

Sep 5, 2006

I bought a used powerbook 15" Ti 1ghz, that upon powering on, or coming out of sleep mode for about 15-20 secs the screen has a pink tint. What might cause this? Is it going to die? Is it something I should repair, or live with? Do these screens warm up? it doesnt bother me to much if it doesnt get worse or stop working.

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

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 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 :: 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.
