Screen lines on my iMac

Recently, two very fine lines going from top to bottom of the screen have appeared on my iMac
I'm assuming it's a hardware problem of some kind...recommendations for resolving? It's a 3 year old Intel iMac. Hopefully it's not unrepairable...

It matters, because people are here from all over the world, and most repair shops only repair from within the same country. Since you are in the U.S. http://www.apple.com/buy offers places which can in warranty repair the machine and these may be able to offer cheaper solutions when out of warranty: http://www.dttservice.com/

HT2807 why is there a horizontal line across my imac screen?

why is there a horizontal line across my imac screen?

Not sure exactly which model your iMac is..?
see > How to identify iMac models
Sadly display lines generally indicate a problem with either the Display or the Graphic's Chip.
To check, take a screen shot of the display using the (Command Shift 3) keys and open it.
If the line is only seen on the Display and not in a screen shot, then it would most likely indicate a Display problem.
If the line shows up in a screen shot, then it would most likely indicate a Graphic's Ciip problem.

There are coloured vertical lines on my iMac screen?

So, I was browsing Safari using my iMac the other day (as I always do), when my computer froze and I had to force shut down. Upon starting back up, I noticed that 1. there were coloured diagonal lines on my iMac screen, and 2. that my mac would not boot up unless I booted it using safe mode. I haven't had an issue with this iMac until now, so I am kind of concerned...
I know that this is not an issue with damage to the iMac screen because, well, when I took a screenshot using shift + command + 4, the coloured lines were still there!
So, I'm just wondering if anyone knows what the cause of this issue could be? I'm wondering if it is linked to Safari (because when I open a new tab, Safari slows down massively and my top sites selection keeps appearing and disappearing rapidly. Does anyone know what is causing this issue and how I could solve it. I hope its nothign expensive like replacing the motherboard...

Yes, it does require some disassembly. Namely, removing the glass, screen and the GPU component. Total war could probably develop temperatures too high.
I don't know how familiar you are with reflowing. This is only a crash introduction, to get an idea what reflowing might include (i.e. not a detailed procedure)...
Reflowing theory to give you some background. Here and here in more detail.
To get familiar with iMac (only steps 1 through 9 apply). After that, GPU component can be taken out, and from that point on, the work is done on the GPU component.
GPU component is then disassembled in 3 key parts. The heatsink, the reinforcement, and the video card itself.
The video card and the heat sink are then cleaned carefully using alcohol from any residue of thermal compound. Any paper stickers must be peeled off, too.
Reflowing. Videos to get an idea how it is done. Here and here.
New thermal compound is applied.
Assembly.
It is a risky approach, especially if you are not comfortable with disassembling your iMac. In that case I would suggest you do not do that at all. Still, even then, I hoped it could give some clue to the issue and you might get someone to do it for you.
Cheers

I have blue and green vertical lines on my iMac which is no longer covered by Applecare. Is it fixable?

What model iMac? Could be a failing video card but maybe not. Is it that way on every screen, startup to shutdown, any time the screen is lit?
Do you have an AASP nearby? Time to have an estimate made. Fixing it will likely be very expensive.

Screen Lines On Mac G5 Display

Hi,
I'm wanting to buy an Mac G5 on ebay. Everything appears to be alright with it but there appears to be lines on the screen.
This does not bother me personally, but will this be any danger to the computer? and if i did want to get it fixed, does anyone know what the problem is?
Heres the listing on ebay

If you read earlier posts this forum you may see that in some circumstances lines on a imac screen can be a prelude to either the screen or logic board failing. Take care. That's what just happened to my imac.

Screen lines

hi I'm getting random screen lines when opening applications on my iMac , there not there all the time
Any ideas

If I look at my phone under light at certain angles, there appear to be vertical and horizontal lines. I know they are supposed to be there because they are very straight and evenly spaced.
And you just changed your point completely and what the iPhone is supposed to do. Before you said that it wasn't on yours, so it wasn't on his. Then you said that flaws were unimportant, when a flaw actually makes it not perfect. And now you think the iPhone just has to make calls and connect to wifi. The phone is actually supposed to do a lot more. Here is a link with what the iPhone does: http://www.apple.com/iphone/features/ If it doesn't perform one of these properly, then they received a faulty phone. This is a lot more than just making calls or connecting to wifi. Also, there could be a problem with how the phone was made, causing the lines at certain angles. An example would be the glue on the phones. This was because the phone was sent out early, causing it not to be fully dry. You may say that it then went away, but wet glue on a phone being used would cause the glass to move and could hurt it in the future

Is it possible to screen share an old iMac running 10.4 with a new Mac Mini running Yosemite

Is it possible to screen share an old iMac running 10.4 with a new Mac Mini running Yosemite. I am trying to bring the old iMac screen up on the Yosemite system

Hello! Not out of the box: OS X Mountain Lion: About screen sharing You'll have to look for third-party options like Teamviewer

I am suddenly having trouble sharing the screen of my work iMac from my MacbookPro at home and visa versa

Neither appear in the shared section of the Finder of the other. This is despite the fact that both are set up with my AppleID and have screen sharing turned on. To make the situation more interesting I have another computer on my home network, an older mac mini. The home Mac Mini does show up in the finder as shared both at work and on my MacbookPro at home. It is set up in the same way as the other two. I can screen share my mac mini from work or my work iMac from the home Mac mini. I can even share the mac mini from the work imac and then share the macbookpro from the screenshared mac mini! I can also screen share my work imac from the mac mini at home.
I have checked my settings on all 3 computers and they seem to be exactly the same.
The home MacbookPro has OS 10.9.2
The home Mac Mini has OS 10.7.5
The work iMac has 10.9.2
This has been very frustrating and puzzling. Any help would be much appreciated.
Thanks!

Can I add a second screen to my 09 iMac?

can I add a second screen to my 09 iMac?

Welcome to Apple Support Communities
Of course. Just get a monitor and the Mini DisplayPort adapter you need to connect the Mac to the monitor. I recommend you to use HDMI if the monitor uses it. Also, you can connect it to a TV. See > http://support.apple.com/kb/HT4241

My screen on my 24" iMac flickers as if the power is flickering.

My screen on my 24" iMac flickers as if the power is flickering then appears to be frozen and it only happens when I'm online. This is a new issue? Any reason why this may be happening? I'm running 10.5.8 and this has never happened until recent. Could my power strip be failing? I hope nothing is wrong with the computer itself. it's only 2.5 years old.

seems to only happen when I am charging my phone on it. I recently updated to a smartphone. Could that be the issue? Maybe not charge my phone with my computer? I hope someone can help.

2nd Gen iPod with Vertical Screen Lines

I've got a 2g iPod (10 gig) that has vertical lines in the screen that no longer work. This a monochrome lcd so I figured that it was a faulty connection between the board and the glass. So I opened my iPod to investigate. there's a plastic ribbon connector sheet with embeded metal connectors that go from the main board to the screen. It looks like pressure from the click wheel's outer ring has stressed the 'wires' in the plastic sheet.
The ribbon connector is folded into a Z shape going from the bottom of the screen to the PCB. If I push up (as in from the bottom toward the firewire port) on the fold in the connection ant the bottom of the screen, all my screen lines, one by one, quickly jump into action and begin functioning normally. However I haven't found a way to make this permanent. I don't expect there's any way to replace the plastic connector. I think the more I move it the more stressed and broken the wires will become.
Has anyone ever fixed an iPod with this problem. Any experience with fixing or working around this type of ribbon connector problem?
I'll be working on it tonight but I want to see if anyone has any suggestions.

Well I decided it's definitely a manufacturing error. Every time the menu button is pressed it pushes down the connector a fraction of a milimeter. The button has a small shroud like protrusion. While I can press the wire in and regain my missing lines temporarily, it's clear that doing so further damages the wires. Apparently there's no way to hold the wire in place with pressure because the menu button is in the way (nothing can fit between them).
Anyway I can only see 2 lines of the bite of the apple when my iPod starts up. I fully expect that this will only get worse. Any help, history or suggestions are welcome.

How do i fix Macbook pro retina screen lines?

How do i fix Macbook pro retina screen lines? Little white lines appear everywhere, but i can still see the screen, but it is just uncomortable for the eyes to see them. They are like pixels...

I have the same problem, especially with Chrome gmail and evernote and it's driving me crazy. Anyone with a solution would be amazing!

Problems with horizontal lines on the iMac. Someone knows the solution?

For several months my Imac has horizontal lines have been growing. Problems with horizontal lines on the iMac. Someone knows the solution?

You have 14 days to return the computer w/no questions asked. Plus you have 90 days of FREE phone tech support on top of your standard 1 year warranty unless you also purchased AppleCare which gives you an additional 2 years of coverage plus FREE phone support.
Strongly suggest that you take FULL advantage of the above before it runs out. Let Apple deal w/the problems.
That being said, no new Mac comes w/Snow Leopard which your profile confirms you have.
Mac OS X (10.6.8)
