Lines across 23" cinema display

I have a 23" cinema display, a frenzy of lines appear on the screen making it useless. I've hooked it up to 3 different computers same problem. Tried screen capture (screen shot looks fine) this is not a graphics card problem. Does anyone know what part needs to be replaced in the screen to fix this problem

Just to keep you all posted:
Apple is sending me a new ADC-to-DVI Adaptor. In the mean time, I borrowed my colleague's again and it seems to be working perfectly after one modification. Instead of laying it horizontally on the carpet, I stood it up in an old external HD holder I got. It now has much more air flow, is cooler to the touch, and I don't have any red flickering lines.
I will let you know if the new one behaves well or not.

Horizontal line across 23" Cinema Display

Hi
I am using a friend's display, and it has an annoying horizontal 1 pixel line across the screen about 40% of the way down from the top. This is the 23" aluminum Cinema Display with the external power brick and DVI connector. The pixels appear to be about 50% gray, but the color changes a little (to a dark gray) depending on the surrounding image being displayed.
Any thoughts about what might be causing this and if there might be an inexpensive fix? (FWIW, I know it is in the screen since it does the same thing w/ various laptops plugged in.)
TIA
A

I had that happen on my 30" ACD. I believe it was caused by a power surge, but could've been just crappy manufacturing. Suffice to say I had display replaced (luckily it happened during the first 30 days).
I hope you have AppleCare for your display so that it can get replaced/fixed.

Red lines & plaid on cinema display when watching DVDs

I bought a MacBook Pro & cinema display in November. The computer's working perfectly but when I watch DVDs on the cinema display, red lines will occasionally flicker horizontally across the screen while the DVD otherwise continues to play normally. After about 10 seconds of this, the screen stops showing the red-lined DVD footage and shows a plaid patchwork instead. Moving the mouse causes a white vertical line to move through the plaid. Turning off the cinema display and letting it rest for a few seconds returns it to functioning normally. The sound works normally throughout. The plaid is primarily lavender and white in color, neither of which colors are prominent either in the DVD imagery or my desktop.
This only happens when I'm using DVD Player, either in fullscreen or windowed mode, and only on the cinema display, not the MacBook Pro's display. I've used the cinema display for 12+ hours at a time with Final Cut Pro (under 10.5.1), Maya (under Bootcamp, with XP), and Rhino (under Parallels), and have never once had this problem. But if I spend more than an hour watching a DVD, I'll experience it at least once.
I've read about electro-static discharge, but that shouldn't be the cause because I've only connected the display to the computer twice, and both times I followed the connection instructions very carefully. I can't find any mention of this problem on this site, but I wanted to ask if anyone had any ideas before I drag the thing and my CD full of photos into an Apple store for them to look at. I'd be thrilled if anyone can give me miraculous solutions, but I'd also appreciate it if you could even confirm that this is probably just a weird hardware problem that replacing the display would fix and that the fact that it only occurs when I'm using DVD Player is irrelevant.
Thanks.

I also have a 30" ACD and I'm experiencing exactly the same problems as you describe, but not only in DVD Player, but as long as the background is black it's possible to see the red lines here and there on the screen. Very, very annoying and it doesn't give me a professional impression of the monitor I so deeply love.
Is this a hardware problem that can be fixed, or should I ask for a new monitor?

Horizontal lines on Apple Cinema display

Hi,
I'm using a 23" Apple Cinema HD Display as a 2nd monitor hooked up to 17" Macbook Pro 2.8GHz/7i via the mini display port. When I play out ProRes from the timeline with the external display set as Digital Cinema Desktop Preview, the image looks sliced horizontally, approximately in thirds, very noticeable when something is moving. It looks like a refresh issue, parts of the screen showing adjacent frames.
I'm befuddled because surely the latest MBP has ample video processing power. The Cinema Display is not latest generation LED (it's 2008), but I understand the MBP & Cinema Display is a tried and tested combination.
The media is on an external drive connected by firewire 800. I'm running FCP 6.0.6 with a Sequence of HDV captured to ProRes422(HQ). Actually, it shows the same issue displaying DV-PAL! I don't see the lines when I play full screen on the MBP (i.e via Digital Cinema Desktop Preview - Main).
Any ideas about how to fix?

Hi bogisan
To clarify, I mentioned in my original post that I'd tested with DV and got the same problem...

Although I'm working with ProRes, I have already experimented with playing out DV on a DV timeline, which should be less demanding than ProRes, as you're suggesting.
It doesn't look to me like the familiar cheese-grater artefact associated with interlacing issue as there's only one break in the image, rather than mismatching alternative lines when there is horizontal motion. I've tried different sequence settings for the field order, with no difference.
I'm wondering if the display is out of sync? It literally looks like the screen has been sliced by a razor 1/3 of the way down, and the bottom part is a different frame to the top. It happens when I scrub through the timeline too, but stabilises once parked on single frame.
By the way, I've also checked that the MBP has switched to the NVIDIA card rather than the slower, less energy consuming Intel video card.
Will check out the MBP forum too...
Thanks

Color Lines on 23" Cinema Display

Hello,
I have a 23" Apple Cinema Display (2003 model). Some time ago a bright, fine vertical line showed up on the screen that never went away. Over time more lines have showed up and in different colors, like cyan magenta and yellow. The lines are always there but only appear prominently on certain colors or shades of gray.
Are the lines permanent? Is it a sign of LCD aging? Can I get rid of them and if so, how?
I hope to find an answer, especially since the lines are appearing at an increased rate now.
Thank you for your help.

My new Mac Pro (2.8 2 x Quad) has also frozen a number of times since day one. The details are over on xlr8yourmac.com with others who are experiencing the same issue.
I usually only get a small spot of screen corruption around the mouse pointer - about the size of a postage stamp - when the freeze happens, but 3 times the screen (30" HC CD) has become totally corrupt with many wavy lines and artifacts running thru it. The mouse pointer stays moveable in all cases, and background processes continue although I cannot force quit or restart in any other way than hitting the power button. Has happened twice in five minutes and then not once for as many as 3 days... seems to have no rhyme or reason.
I also have one of the freezing Aluminum iMacs with the very similar Radeon 2600 Pro card; the behavior was almost identical. Apple eventually released a firmware update that fixed the issue, and I find it hard to believe they would have brought the faster XT card to market without thorough testing, but... it's beginning to seem that they have.

Color lines on my cinema display and computer freezes.

I just bought a 2.8 dual quad-core mac pro and a 23 inch cinema display 2 days ago and I've been having small color lines show up on my screen after running the computer for about an hour. It usual happens when im in safari or firefox. and when it does happen the computer totally freezes. Im not able to force quit or do anything except restart from the power button. This happens again after about an hour or 2 and i have to do it all over again. Any idea why this happens before i lug the computer back to the store? thanks...

Colored Lines on Cinema Display (30 inch) at start up

Sometimes when I start up my Mac Pro (2012 model) I see colored lines on my Cinema Display (30 inch).
It is gone when I press the start switch again.
What can be the problem?
The Mac Pro has a ATI Radeon HD 5870 1GB Graphics Card.

It is sometimes a sign the inverter cable or board is beginning to go that is used by the LCD.

Horizontal Lines Across MBP Display

I am getting horizontal lines across the display of my laptop. The lines do not show-up when I have the computer attached to the external cinema display, and the lines will go away if I run the disk utility, with the only errors being SUID errors that cannot be repaired, and Apple has said aren't an issue. However, the next time I open my laptop, the lines re-appear. I've reset the PRAM, and that didn't work. If the lines are showing, a rebooting of the system does not help. The only fix I've found is running disk utility, but that is a very temporary fix.
The lines are all over the screen rotating up from top to bottom, and multi-colored. The overall display is blurry.
Any ideas?
Thanks,
Will

Unfortunately, that makes it sound like a problem with the built in display. Have you tried running the extended version of the Apple Hardware test? If you get an error code, it might give you a clue.
Do you have access to an Apple Store? I think they have a special diagnostic for the NVIDIA chip problem, so they might be able to pin down for certain if the problem is with the chip or the display.
Good luck!

Cinema Display Vertical Line

Hi,
My Cinema Display (LCD, 21" I believe, came with Powermac G4 MDD 2003) has had a pink / red vertical line in it for quite some time now. It seems to sometimes change color, but is usually redish. It sits right in the middle of the screen, and goes all the way down from the top to the bottom. It is two pixels wide.
I have used another Cinema Display the same on this computer, and no lines, and tried this display on another Powermac, and I have lines.
Are there any warranties for this sort of issue? Any fixes?
Thanks for your help,
Jordan

Lines appearing on the monitor is a product fault with some of the Apple monitors. A quick search of the web will yield 100's of identical reports of the same problem.
I started with one line and now I have 3. You should expect the same. The fact that Apple have refused to address or even a acknowledge this product fault is a disgrace.
I'm sorry BSteely but your suggestion that we should simply replace our monitors because its out of warranty is ********. A product fault is a product fault pure and simple...Its not like Apple monitors are inexpensive, I have several other non-apple monitors and have never had this issue with them. It is the manufacturers responsibility to insure that a product leaves the assembly free of fault.
This is not an isolated problem but a problem in manufacture and Apple need to do something about it to restore goodwill, as I simply will not buy another apple monitor until they prove that this issue has been addressed.

A few months back I Dropped my iPhone 4 and I cracked my screen and now i cant unlock my phone due to touch screen not working plus there are blurred lines across the screen and I can't see anything that it displays.
Now when I try too connect my iPhone 4 to iTunes on my computer at home an error message comes up saying that I have to unlock my iPhone 4 for it to communicate to my device.
But the problem is that I can't unlock my iPhone 4 because I'm unable to see the key pad and my touch screen no longer responds when I touch it.
I just want to reset my iPhone 4 back to its Factory Settings & start all over from the beginning.
How can I unlock my iPhone 4 with iTunes on my computer or any other option you suggest me trying.
Thank you in advance,
SiHero

If you have had a "local guy "repair your iphone you will not get any support from Apple for warranty OR post warranty
If Verizon return it to Apple it wil not be handled by Apple
If Verizon also use unauthorised repairers you may be lucky
(Apple do not sell parts to local guys or anyone else )

Dreaded iMac lines symptom hits 23" Cinema display!

Have a 17" iMac that developed the "lines" symptom within a month after the factory warranty expired - that computer is all but useless now unless I spend the $700+ to get the display working again (& who knows how long the fix will last...)
Now, the 23" Cinema display I've owned for less than a year is developing similar symptoms. Was editing some images today that had solid darker gray patterned backgrounds when I noticed the vertical lines - 3 or 4 so far. They look different (smaller, less distinct) than the ones on the iMac, but sure enough they're there - vertical lines throughout my less than 1-year old Cinema display!

If it's a G5 iMac, it may be covered:

That could be the graphics board. Anyway, the display is still under warrantee. Also, you still have a chance to buy AppleCare for it.

Apple 23" Cinema Display - lines around windows

I have the Apple 23" cinema display and now I'm seeing "ghost lines" around open windows on the desktop, and also along the sides of application windows, like Safari. What is causing this?

having the same problem, you can see right through to other open windows ie. photoshop/acrobat documents. not very good when retouching images etc.

HT2810 I have a thin blue line running down my 24" Cinema display, how can I remove it?

I have a thin blue line running down my 24" Cinema display, how can I remove it? or is it a fault.

It is a fault and the only way to fix it is to have the screen replaced.

TS2771 My Ipod touch displays white lines across the screen. I've turned it on and off but still shows up HELP!!!

My Ipod touch displays white lines across my entire screen. I've turned it on and off and it still hasn't cleared up.HELP!?!

Try the standard fixes:
- Reset. Nothing is lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factory defaults/new iPod
If you still have the problem that points to a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

I contacted Apple and they went through all the tests and agreed that it has to be replaced.
Cheers
