See the pictures. They look almost like ink but no ink has been near the screen.Tried cleaning the screen but with no luck. It lies on top of any open window.

As you can see from the video there is a strange black area surrounding my windows, but only when there are "active," not when I click on the desktop. The iTunes window is unaffected. Additionally the Quicksilver command interface and the Dashboard have a discoloration which is very annoying. Do you know what could be causing this? This behavior goes away when I restart my computer but eventually comes back. I have not been able to tie it to a specific app yet.
This is on a white macbook that I've had for almost two years, but this only about one month old. It didn't use to happen very often but nowadays it happens almost every day.
So for the first time in over a year since I purchased it, my iMac crashed twice.The first time was this morning, i went to do something and the screen went black, and my secondary display got black and white lines. I had to restart. And the boot screen with the apple logo hung around for a while.
Then, later on the screen went whacky after trying to wake it from sleep (not full sleep just display sleep) and had a bunch of moving lines and then I couldn't see anything. So luckily I got a picture. After restart, it seems fine.I'll call apple care in the morning, but thought i'd try my luck here.
i have had a Macbook Pro which I got in mid 2008 and it just yesterday began doing something strange. After working in Mac OS X for a while I saw that many of the white areas on my screen were filled with purple lines. Most of my pics in my background are outlined with varying colors and I cannot figure out what is going on.
I began to suspect the graphics chip at first, so to test this theory I plugged it into an external display and the problem did not exist there so I concluded that it was not due to the graphics chip. I have a friend who performed some tests and believes that it is a problem in the connection between the monitor and the graphics chip and that certain bits of data just aren't making it through. I thought that this was a feasible problem, but to get a second opinion I took it to the local apple store on my university campus and they looked at it and also concluded that it was not a graphics chip problem, but that I may have to replace the whole display assembly. This was fairly expensive and I cannot afford to do that since time got away from me and I forgot to purchase applecare. (How stupid of me. Aargh!) Anyway, so I was wondering what is believed by the macrumors community to be the best option. I discovered that this problem seemed to happen on a lot of this particular model of macbook pro and that apple offered to replace the graphics chip for free because of it, but since they do not think it is a graphics chip issue, it appears that I am stuck.
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.View 7 Replies View Related
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.)
My 2008 MacBook Pro (17in) has just started up with a white screen and strange black marks - almost like ink spilled on white paper. I cannot get anything else.
Info:MacBookPro, iOS 5.1
My MacBookPro 15" 5.3 worked fine until today, All the blacks (rgb 0,0,0) on the screen become red stripes.
When I boot into Linux or Windows the same problem appears, so it's probably a hardware problem.
I have no expensive adaptor to connect to an external lcd screen, so I don't know yet if the problem is in the mac screen or in the cabling or somewhere else...
Here are 2 screenshots of black squares a drawed in Illustrator, one taken on the mac (cmd + shift + 3)
one taken with a camera (where you can see the red lines)
I want to avoid the MacStore as I want to avoid missing my laptop for a month...
I've had my iMac for over 2 years now. Last Thursday, I left it on for more than 3 hours and it started having black and white verticals lines appearing on the bottom and top part of my desktop and the cursor. Yesterday, when I checked it again, it was still there! What can I do to fix it, WITHOUT going to a Apple store?
iMac, iOS 3.0.1, URGENT!
Sometimes my MBP gets these faint black lines that seem to start at the bottom on the screen and fade away as the near the top of the screen. I took a picture. Anyone know what causes these?View 10 Replies View Related
Simply using my Imac for watching tv on the web, Hulu, and left to help my wife get groceries in the house. My wife checked her email and closed Safari.
I came back in roughly 10 minutes from when she shut down Safari to see a black screen with white pinstriping, and the mac being totally unresponsive. Shut down and rebooted, sent off the report to Apple, and am now here with seemingly no problems.
Needless to say, as a photographer this computer is just about as important as my camera. Should I be worried? discovered the thread to this issue, which appears to be quite extensive.

my macbook pro has been freezing and crashing lately. the screen ends up looking like this: [URL]
i have checked/repaired disk permissions.
not sure what could be causing this problem.
Something has changed with Preview on my system running Leopard. For some reason, most PDFs opened in Preview have strange lines in them. But if I open the PDFs with other apps like Adobe Reader, there are no lines. Anyone know what these are, why Preview is displaying them, and how to get rid of them?View 12 Replies View Related
First of all I'm new here so just wanted to say 'Hi', its been great to see all the discussions on these forums and they help a lot with buying tips and troubleshooting so thanks.
Problem #1 I purchased a refurb 24" 2.8GHz imac early May and have been using it since then and so far other than the "normal" gradient issue and a brownish tinge around the edges of the screen it has been good.
Lately I've been using Aperture a lot and first started to notice that in some pictures especially ones with quite a bit of highlights like clouds that there are small hatch like patches in all the pics. I know it isn't the pictures but the imac screen itself as you can see it on the desktop as well. It only seems to be centralized in the upper left hand section of the screen and they seem to be lite purple/blue in color. And like I said its only in patches in certain spots on the screen. Don't know if I'm being over anal about this or is this a problem?
Problem #2 I switched to a solid blue background to check the above problem and notice that there is screen burn in of the top and bottom header in the outline of my firefox window on the blue screen. Between switching windows often and applications very frequently and not leaving the computer at all... what the heck? Not normal for imac screens is it? Heat issue causing burn in? Hasn't been an issue with any other LCD I've ever used.
By the way the imac came in a new white box and was wrapped like new in perfect condition but I popped it open without ever starting it once to make a hard drive swap and the thing was definitely a bit dusty inside so in now way was it just used for a couple weeks before being given back to apple.
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 happenView 7 Replies View Related
After I updated to 10.5.7 I experienced a few issues. First of all, after the initial update I restarted the computer than I got a black screen that said "No bootable disk found" or something along those lines, this was fixed after 4 restarts. Also after the update i experienced problems while trying to browse the internet. Some pages would load, but others, like google, and theMacrumors "forums" page, wouldn't load completely. I was just wondering if anyone else had experienced issues like this or anything similar.View 13 Replies View Related
I came back from work to wake up my iMac. It made the noise but the screen stayed black. I tried restarting by holding the power button- I can hear it start and the chime but still have a black screen. I tried resetting the pram, and unplugging the cord but I still get a black screen. I can hear the chime though; I'm not sure if that means anything. I just had the hard drive replaced in February so I hope it's not that. just wanted to clarify that when I restart, I get the chime but the screen stays black- I don't get to the grey screen. So I'm assuming right now that my display may be shot?

I have a 3.5 year old 17" Imac. About a month ago a pink vertical line appeared on the screen. Today its been joined by a blue one and a yellow one. I don't have applecare and I'm out of warranty.View 2 Replies View Related
I use an Intel white iMac 2.0gHz as my primary computer. So far, it has given me no trouble. However, lately I woke the computer to discover a yellow line of dead pixels all the way to the right of the screen. It was discouraging but since the line was out of the way, it wasn't a great deal. However again, later today, I woke the display to find another line running down the middle of the computer. Oh gosh! Anyone know what is going on? Is it the display or the graphics card?View 6 Replies View Related
I'm looking for some information and possible repair tips for my cousins iMac G5 (First Gen) 1989. I don't know anything about mac's, I've always been a PC user. But, I recently fixed both my aunt's laptop and desktop (both pc), so my cousin asked if I would take a look at her mac, as well. Basically, when the iMac is turned on, the screen goes weird. It fills with a bunch of lines (both horizontal and vertical), some spanning the entire length of the screen, and some being only about half an inch long. The lines don't stay stable, they flicker and change positions every few seconds. Behind the lines, you can see the black screen with the apple on it.
It doesn't seem to get past this point though, it seems to freeze and never leave the apple screen, although the flickering lines continue to change. I tried jiggling and moving the power cord around, and whenever I moved it the lines on the screen seemed to change positions. I also tried taking hold of the sides of the monitor (machine? I have no idea what mac-speak for anything is) and very gently pressing and "twisting", and this changed the lines as well, at one point it turned to all vertical lines spanning the entire length of the screen. We opened it up to see if any wires were loose inside or anything, but there really weren't any exposed wires that I could see that I could even try to tighten/adjust. Right now it's not even usable.
My iMac (which was bought in september of 2006) fell around 2 months ago and cracked on the left side of the screen. It wasn't such a big problem until blue vertical lines began forming around the crack and now spreading. Now I don't know what to do, would it be cheaper to get it fixed at an Apple store or can I replace the screen, and if so where would I be able to buy an LCD 15" screen?View 1 Replies View Related

I've got a friend with a 17" PowerBook G4 that's suddenly started displaying a vertical strip of black lines about 2" wide. Any idea what's causing the problem? I've seen plenty of pictures of PowerBooks with pixel-wide strips of a single color, but none that show black lines. Something else to note is that the problem area is displaying a shadow of the previous window that was there (ghosting).
He's tried all the usual, from rebooting to rubbing the problem area to pressing the metal strip above the keyboard to try and reseat the ribbon cable.
My Mac Pro crashed yesterday after it was reading an empty DVD, and now if boot the Mac it shows this screen:I have tryed rebooting it in safe mode, does not work, I get the same screen. Tryed to use a other monitor, same problem. Now, If I press the Eject button, the disc tray will eject and if I press the volume button it can be heard.
Let me start by saying I have swapped the ram in the computer and the problem persists. I've also tried resetting the PRAM. I have unplugged all devices except the keyboard and mouse. I have reformatted and installed OS X Leopard, Tiger and Snow Leopard. I have even encountered this issue while the computer was running from the install disk. I'm pretty sure software, ram and third party devices can be eliminated from the possible causes. The computer continues to run after the screen goes black. I am connected to it right now using screen sharing, so I know the computer is still working. Putting the computer to sleep and then waking it up temporarily brings the screen back until its next random blackout. I have opened the computer to replace a dead HD, so I suppose it is possible that I knocked something in the process, but I did that back in December and the problem is a relatively recent development. I would really prefer to fix this myself, if I could only figure out what the problem is.View 6 Replies View Related
I have been experiencing some unusual problems with my imac. While on the internet today my computer crashed on me twice, the first time the screen just showed a bunch of vertical lines, the second it flashed some random colors then went black. After the screen change the computer was unresponsive. I have a bad feeling, is it due to overheating, a bad logic board or something else. This is the first time I have ever experienced this on a mac. Has anyone had any simiar issues? Or am I up **** creek? I can't really afford a new computer seeing that I just bought an iPad (it comes Saturday). I am not sure if my computer is still under apple care and even if it was I won't get it back by the time I have to go back to college. I attached a screen shot of my computer temps.View 3 Replies View Related
When I turn my Imac, it goes from the white screen to a black screen, then blue and then desktop. The whole process is fast, but is not normal. (at least is not like my previous MBP or the videos that I have seen on youtube) At the black screen stage, I can see some boot up information, etc, It is fast so I am not able to read it all. It looks like when booting an old windows or dos machine How can I change this? Is this normal? It also shows the screen when I shut down.View 1 Replies View Related
When I try to type an uppercase letter using the left hand shift key, the screen background turns black and no letter appears.

I have been limping along for quite some time with a recurring problem with my PPC Flat Panel iMac G4.Sometimes when starting up I would get a black screen. The unit chimes at startup but the screen would stay black.I found that I was able to fix (temporary) the problem by removing the bottom plate and pushing the reset button under the base.(After shutting down and unplugging the unit.) after the startup chime, the screen turned gray with a folder icon in the center with a blinking question mark.After shutting down and restarting, this happened again 3 times.On the 4th shutdown/startup it went back to the black screen.Repeated shutdown/restarts have no effect.Shutting down, unplugging the unit and pushing the reset button is also having no effect.I hear the startup chime every time. Black screen every time as well now.

Over the last few months I've started to notice my Macbook Pro (13" Mid 2010) developing display issues.. every now and then the screen will freeze and black spots/dashes/lines will appear on the screen.
My mac is fully up to date and I can't seem to work out why this keeps happening?
I've included some screen shots so you can all see what I'm talking about. Thoughts?
Macbook Pro 13" (2010), Mac OS X (10.6.6)
The screen randomly turns black without any major reasons. It doesn't seem to be a sleep mode/screen saver thing as the music continues to play on. I can adjust the volume or pause the music with the keyboard but the screen just won't turn back on. I have to shut it down using the power button and it happened several time the last couple days. Anyone else experience the same thing and got a solution?View 4 Replies View Related
