30" vertical banding issue (thick grey overlay)

I have a 2 year old 30" display which has recently begun having some issues. The problem has only happened twice so far, once 1-2 months ago, and the again a couple days ago. What happens is randomly the screen will get light/dark vertical bands of various thicknesses and intensities. It will stay like this regardless of restarts, leaving the computer and display off for 6+ hours, unplugging and replugging all cords, changing resolutions, plugging the display into other computers/laptops, etc.... for about two days. Then it will "fix" itself.
See pictures here:

I have AppleCare and called support about this issue just now. They won't give me a repair ticket or replacement unless it happens again, in which case I'm supposed to call again, and they'll let me ship it in for repairs. My frustration is that it's happened twice, I'm sure it'll happen again, however if I can get it taken care of now, while I"m between photography projects, then it's a minimal impact, however, if I wait, and it does this again while I'm under a deadline working on a photo shoot, then I'm screwed. I explained this to the support rep to no avail.
I'm going to try bringing it to my local genius bar tomorrow and show them the pictures, since now the display looks normal, and see if they can help me any.
I guess i have two questions:
1) has anyone seen this before? I see many posts about thin colored vertical lines, but I haven't seen this issue before.
2) any suggestions on how I can handle getting a repair or replacement taken care of?
Thanks!

Video Artifacts/Vertical Banding issues

I have included a link to an example of some extreme artifacts/banding that is occuring on my new Radeon 9800 Pro Mac Edition (256MB version).
http://www.htadgroup.com/crazyscreen.htm
This card is brand new...was installed for the first time this evening on a Dual 1 GHz G4 / 1.5 GB RAM / OS X 10.4.3.
I have downloaded and installed the latest ATI control panel and ROM flash update and both updates went smoothly...no help with the issue. Reinstalled the 10.4.3 update thinking it may be an issue there...still no luck. The issue has occured from the first moment the computer was turned on with the new Radeon card in the AGP slot.
Anyone have any ideas as to what may be going on?

Hi Rustus !
Nice desktop pattern in the picture......
Do you have the same results at ALL given resolutions, or just at that resolution..?

Macbook display issue - vertical band

The LCD display on my daughter's Macbook got fried because she dumped a drink on it - yes, it was alcoholic. She had some else's fried MacBook laying around so I harvested the LCD display from it and put it in her Macbook. The swap went just fine.
I booted her machine and found a vertical stripe on the right 1" of the display.
You can see the stripe in the photos here:
http://gallery.me.com/carlfino#100011
I checked the connection from the video cable to the lcd display and all was well. I know it's not the connection from the motherboard to the video cable because this stripe did not exist on the previous display and I didn't affect this connection when I swapped the lcd display.
I have no history on the display that I placed in the unit, so I guess it's possible that this stripe was a problem embedded in that display. But, if any of you have suggestions on what could cause this I'd like to hear them.
Regards,
Carl...

I have not tried an external display. The only time it is not there is on bootup, when the grey screen shows. As soon as any colored desktop image shows up the band is there. I also removed the video display cable from the back of the display while the machine was running. As soon as I removed the video cable, the screen went grey, and the band was not there. When I plugged the video cable back in, the stripe returned. Clearly, it's a video problem - the question is whether the problem is rooted in the motherboard or on the lcd display side. I suspect the lcd display, because even though the previous display had liquid damage, I could see the entire display and the vertical band was not present.

Vertical bands on my 17" LCD

Something very odd happened to my 17" LCD this morning. Instead of the usual picture-perfect clarity, I have vertical bands or stripes across the screen. They vary in color from white to grey to blue to black and vary in width. There is no hint of what should actually be displayed on the screen (i.e., the login window for my G4 cube). Also, the outside 1 or 2 inches of the screen is black, as if the screen has a cataract that has blurred the peripheral part of the screen. I've tried rebooting, but no luck. I connected the G4 cube to a different screen and it's working fine, so it's definitely the monitor at fault. This monitor has been connected to this same G4 cube for about 5 years without issue. Has it just reached its lifetime limit? Any suggestions for a potential fix will be most appreciated.

A second purple line appeared along side the blue/green one. These discussions show a problem exists with these lines on their displays, and although they made no acknowledgement of this, The Apple Store replaced the LCD in record time, although I was told at first I would have to wait a month for a new LCD. A new logic board was tried first but did fix the LCD, adding two hundred megabytes of data to my hard drive for diagnostics. I recloned my hard drive to clean it out. Without Apple Care (I'm half way through the three years) this would have cost $700 or more.

Black & White Vertical Bands on Freeze

For the past few weeks my eMac has been randomly freezing and the display is filled with thick black & white vertical bands/lines. The applications seem to be running in the background when this happens (iTunes was still playing) but I have to hold the power button to shutdown the computer as it won't display anything on screen other than the black & white bands.
Does anyone know what this is/how I can fix it?
Thanks

The symptoms you describe of one of a set of many which may indicate that your eMac 1 GHz or 1.25 GHz machine uses a logic board on which there are defective capacitors.
To determine if this is the case with your logic board, you may remove the user access place on the underside of your machine and inspect the visible capacitors. Affected boards typically will show evidence of swelling, bloating or leakage of fluid from the capacitors.
While Apple once covered the replacement of such logic boards, the repair extension authorization for this issue expired long ago. You can alternatively have your logic board repaired if it is affected by this defect. Contact me at the electronic mail address listed in my Public Profile if you are affected and want to explore such an alternative.

Banding issue with brand new MG7550 in Win 8.1

Hi there,
I'm running some test prints on a new Pixma MG7550, but I'm getting a consistent vertical banding on landscape photo prints (i.e. horizontal bands on portrait prints). It's really noticable on gradients, but is there regardless of colour. It looks like a slightly darker line every 8mm or so.
Here are the details:
Pixma MG7550 (Firmware 2.020)
Windows 8.1 Pro 64 bit (Auto update enabled and up to date)
Printer installed on network via ethernet (no other connection)
Canon inkjet printer driver 2.80
Stock (included) cartridges installed
Printing from Windows photo viewer
A4 HP glossy photo paper (landscape mode)
For what it's worth, I was very careful in the setup process and followed all the instructions to the letter.
The print tests look fine, no missing content or obvious errors. The printed image looks just like the reference one.
I've run nozzle checks, head alignments and the clean utility.
I haven't run a deep clean as I understand that this is only necessary when you are sure it is a cleaning problem and I really don't know.
I've updated the printer firmware, but the problem is exactly the same, before and after.
I suspect it may be a Windows 8.1 issue, but only because the Canon site refers to a similar-sounding problem in Windows Vista (where it suggests upgrading to Service Pack 2).
If anyone can offer any ideas, I would really appreciate it.
Thanks!
Solved!
Go to Solution.

Glad it worked out.
I have a Pixma Pro-100 with XPS driver, so my experience is based on that, but I believe they all work the same. As far as the XPS driver is concerned, when you install the XPS driver the computer sees two printers - an MG7550 and an MG7550XPS. If you don't make the XPS printer your default printer in Windows, or specifically choose the XPS printer from the Print menu of your application, then the XPS driver isn't being used.
There is also a lot of Internet discussion over whether or not Windows has a 16-bit printing process.
I have experimented with both. 1. I have not seen a photo printing quality difference visually with XPS over non-XPS. 2. Using the XPS driver hasn't created any negatives that I have seen. So, I use the XPS version just in case there are some subtle benefits I don't see.
But, if you want XPS then you need to be sure to select it.
The print head sticking option moves the head further from the paper; usually selected for heavier weight paper. I don't know anything about the HP paper you are using, and don't know if there a re negatives with selecting it for lighter weight paper, but since you made two changes I would suggest you uncheck that option and print from PS just to see if there is a difference.

Wide black vertical band in display.

My computer (MA590LL-late 2006) has just started displaying a 2.5" wide sold black vertical band just left of center. Otherwise it seems to be working just fine. I want to find out if this is an expensive repair before I take it to Apple because, given it's age, it may not be worth fixing. I found one similar problem within these "Discussions" pages but there was no answer. Can anyone help?

If your waranty's up in 6 days, I'd ship that thing off first thing tomorrow by whatever method it takes. On the old Titanium PowerBooks (and actually on some of the Aluminums) that line meant a pinched display cable or something in the display itself failing. Whatever it is, it's not going to just go away, in fact it will probably just get worse until you have to pay to either replace the display (very expensive) or get it rewired (rather expensive.) I'm certainly no Apple tech, but a line problem like that is usually a display issue needing attention before it becomes worse. Even though you'll be without your computer for a while and it sounds like it'll be a pain to ship it and get it back, I'd still give it a try.

Thumbnail/Quick Preview/Export have strange grey overlay

I spent quite some time googling this issue, so it's starting to seem like a "just me" issue. Yet I can't find a way to solve it, so here I go asking for help.
I have a library with a single project and a series of photos in it. Most photos have a crop, white balance, exposure, sharpen and curve global adjustments, as well as areas with definition brush strokes and dodge brush strokes. The dodge brush was used to make the "almost white" background around product in the shot completely white.
The thumbnails display a light grey (around 250;250;250 RGB, although it varies a bit) blotchy overlay in the areas of the image that are expected to be white. When I click on a thumbnail to bring up the larger image into view, for the first few seconds, while the "loading" spinner is visible on top, the grey overlay can also be seen on the enlarged image. After loading is finished, it disappears. If I turn on the Quick Preview mode, the grey overlay persists and does not go away. Images that I have viewed enlarged with Quick Preview turned off continue to display correctly when I come back to them after looking at other images, as if they are cached in memory. After I view a few dozen images, though, these correct versions seem to be evicted from cache, and I get the grey overlay during the "loading" period again.
The grey overlay does not correspond one-to-one with the area where brush strokes have been applied.
The scariest part of it all is that when I try to export versions, they are exported with the grey overlay intact.
I have tried rebuilding thumbnails, reprocessing masters, repairing permissions, repairing the database. The problem persists. I have tried disabling the dodge adjustment but unchecking it and then checking it again. The problem persists. I have tried removing the dodge adjustment and then brushing it on from scratch. The problem persists.
Out of ideas now. Please help. I would love to attach screenshots, but don't see an option to do so.

All you are seeing is the difference between the fully-decoded image created on the fly by applying the adjustments saved as instructions in the Version text file to the Master image file, and the Preview created according to the parameters you set in Preferences.
If the Previews don't meet your needs, try a higher quality/larger dimensions.
Likewise for your exports.
What are your Preview and Export settings?

Vertical banding lines on iPhone4 still capture

I found that there are vertical banding lines on captured images. on another iphone4 there are no such kind of vertical banding lines.
Is there anybody who has the same issue?

i dont have vertical lines but there's a darker spot when i tried to take pics on light coloured background. and the spot gets bigger and switches to another place when i tried to take video. it's definitely the camera coz i dont see the spot when i looked at the pictures i imported into the phone.
does that happen to anyone else?

T410s vertical band in my LCD

I have had my t410s for a couple of months, yesterday a vertical band appeared in my display. A quick search online brought up this: http://www.youtube.com/watch?v=rM9_ZM_8qkQ
which is exactly what I see.
I am about to lose my t410s for a couple of weeks (or so I am told by the Lenovo support rep), is this a problem that Lenovo is able to reliably fix? (namely it is clearly endemic to the t410s as I have seen many posts on the matter, my concern is that their fix is just temporary until it happens again)
Do others who see this problem find that the repair sticks?
btw, I have to say that the Lenovo return mechanism which required me to talk to someone I could barely understand did not help. I used to love the Thinkpad line for its robust design (and had many), the T410s, which was not inexpensive, felt flimsy in comparison and having the screen die in such a short time is disconcerting (and seeing how many people are dealing with the same thing is a further concern).
Solved!
Go to Solution.

For the record: Technician came and replaced the LCD. Took maybe 10 minutes. Works perfectly now :-)
I asked him if he noticed anything about T410s displays failing and he was not aware of any issue with that particular model.

Strange vertical bands on Starz HD

I'm seeing distorted vertical bands on the Starz HD channel, and it appears on all of the televisions in my household. Is it a problem with my ONT or a network issue?

Welcome to Apple Discussions!
This sounds like it could be a hardware problem either with the display or possibly the graphics chip. Since you are under Apple's 1 year warranty, the best thing to do would be to contact Apple and see what they recommend you do to have it repaired. I don't know what the resources might be in Kenya, but if you bought it locally, perhaps the store where you bought it could be of help.
Good luck!

Vertical banding in KDL60W630B

Overall the colors and image is quality of this TV is good. However, in the scenes with solid background colors (like the sky), the vertical bands become visible when the camera pans horizontally. I'm trying to decide if this particular TV is defective or if all the Sony KDL60W630B has this issue... Here's the picture of my TV with vertical banding (you might need to copy and paste the link below, clicking on it seems to be not working) http://bestbuy.ugc.bazaarvoice.com/3545w/279626/photo.jpg Thanks.

Severe banding issue in shadow areas

Short Version: Having severe banding issues in shadow areas in Lightroom. Need to know how/what to set my color profile to to fix this issue. Lengthier description and images below.
I have read several posts here in the Lightroom forums about others who are experiencing the same type of banding issues, but I haven't seen any definitive answers on how to solve the problem.
I was able to take a couple screenshots of the issue that I am seeing. The image looks very different in Photoshop, Lightroom, Windows Photo Gallery, and also rendered in IE7. Screenshots of the image in Lightroom and the image in Photoshop are posted below at a 100% crop of the affected area. The first image is how it appears in Lightroom and the second image is how it appears in Photoshop.
From what I have read elsewhere the problem has to do with how Lightroom uses color profiles. I do not have much experience with color profiles, so I'd like to get everyone's recommendation on what color profile I should be using, and maybe a link to some information on setting color profiles and how to fix this issue. The image looks so much different in Lightroom than it does elsewhere, that I can't see myself being able to trust Lightroom to process my images.
Some info on my setup. Shoot RAW with Canon Rebel XT. Use a Dell with Pentium D running Windows Vista. Monitor is a Dell 2007FP, and currently I am using the Dell 2007FP color profile as far as I can tell.

Don, Bob!
I think it is quite obvious that the Eric's problem is not banding per se (and the related cure by fiddling with black setting), but rather about the mismatch between how the file looks in LR's Develop 100% view and how the same file (or an exported file) looks in Photoshop.
Eric!
I am afraid there is no definite answer to this problem. Indeed there are a number of Windows users that have reported this problem. A very exhaustive and inconclusive thread is this:
http://www.adobeforums.com/cgi-bin/webx?128@@.3bc3578d
The bottom line so far seems to be this:
LR on Windows uses Windows ICM to generate how the image looks on the screen, while PS uses Adobe own engine to generate this. Somehow this set-up appears not to work reliably with LR - the on-screen image in LR 100% develop differs from the same file's appearance in PS or other color managed applications. The mystery here is that other applications that seem to use Windows ICM still manage to show image correctly, but not LR. But anyway, the Windows ICM appears to be the culprit here.
The amount of difference people see depends on the complexity of the monitor profile used. LUT based Version 4.0 profiles will be affected worst - not only shadow detail, but the overall tonality and colors may be off. The best match is achieved with simple matrix based version 2.0 profiles - on my machine the mismatch occurs only in deep shadows were I see banding/splotchiness in LR and only under certain Develop settings.
(Incidentallly, on Windows XP (and older) machines one should ALWAYS use ver 2.0 profiles, as Windows ICM does not support ver 4.0 profiles. I also think that Windows ICM cannot handle LUT based profiles correctly. My own experiments showed that using LUT based monitor profile resulted in mismatch between PS CS2 and other applications (like Canon DPP), not only LR. BTW - as you are using generic monitor profile, I can almost bet that it is a matrix ver 2.0 profile (good thing).)
I am curious about the Vista thing though. I had certain hopes that this image appearance problem in LR would be eliminated on Vista, as it uses the Microsoft's new Windows Color System which incororates an updated ICM that now supports ver 4.0 profiles and reportedly has many bugs of the previous ICM fixed. However, if your report is true and the image mismatch is not due to some other factors, then it seems that Vista does not solve this.

Dell u2410 BANDING issues

I use my DELL U2410 as my external monitor and I got some banding issues in some of the color. Especially in Blue and Black. It looks very pixelated.
The driver provided by DELL is only for Windows and I tried to look for somehting online to see if there is a driver out there but couldnt find any.
My display settings are
Colors: Millions
Refresh Rate: 60 Hertz (NTSC) (I cant change to PAL and I am in europe). Could this be it??
Option: Overscan is ticked.
Any idea guys?

Have you tried a new cable?

2007 MBP LED Banding Issue

Short backstory: My mac was working fine, except when I would open the lid to wake it from sleep it would turn on the display, but not the backlight. Sometimes the backlight would take 5 seconds to turn on, sometimes it would take upwards of a whole minute to turn on. Adjusting the brghtness controls on the keyboard didn't make any difference, so I decided to do some reasearch and followed instructions to reset the PRAM and SMC. The delay has gone away, but now I have a new problem.
My MacBookPro3,1 LCD backlight seems to have light banding issues on the bottom of my screen. It seems almost like if it a row of lights that ever 3rd light or so is out. Is this a software problem of a hardware problem and is it an indication that my screen is about to go out?

Welcome to the Apple Support Communities
That's a display issue. As you have had problems with the display before, it looks like the display is damaged, so take the Mac to an Apple Store or AASP
