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.

Macbook display issues

Hello!
Way back a few months ago when I purchased my MacBook, I had some display problems from the beginning. I talked to a service rep and they walked me through some potential fixes but eventually sent out a box for me to return my macbook in for repair (I am an hour and a half away from closest apple store). I am a full time student, however, and did not ever get a chance to send it in. Later, I had issues that made my macbook unusable, and was forced to send it in. I was hoping that the display issues would have been fixed as well, but they weren't. Luckily, I primarily use an external display. But my problem has gotten worse and worse, my macbook is almost unusable on it's own at this point.
I know I am still under repair warranty and was hoping someone could send a box out for me to return this before my fall term begins, so I could use it for note taking again. But I can't go into an apple store and I don't have phone support anymore, so I have to post this on here because there is no email support.
I hope someone can help me!
Thanks a lot,
KJ

I know you only get something like 30 days phone support but i think thats more for simple things if you get stuck or need help using something. You have a full years warranty so if you have a problem within the year you should be able to phone them up and get your problem sorted out under warranty. They will probably ask for your serial number but you should not have to pay for phone support. Just call the number listed on the apple site.
When you speak to them make sure you tell them ALL the problems you have with your machine. When i sent mine in i made a text file titled 'Problems with this macbook' and left it in the middle of my desktop with the background image turned off to make it more visible. I dont know if the engineer ever read it but its an extra step that might be worth taking. You should still tell the guy on the end of the phone about all your problems though. They may well assign a work order to your machine going by what you tell them so if you only tell them about one problem the engineer that looks at it might not know to look at anything else.

Unibody Macbook display issue and keyboard backlight issues while booting

I have a 13" aluminum macbook which has been having some issues when booting up. The machine seems to be booting just fine all the way up to the log in screen. The display is normal and everything seems fine. After I log in, the various pieces of the screen start to display (desktop icons, menu bar, etc) and my wallpaper is visible. After a few seconds, the display seems to degrade and the wallpaper image is visible but distorted. It is almost as if the machine is in some sort of safe mode (pardon the windows reference).
Normally, I have my macbook connected to an external display and external mouse/keyboard. After a reboot, this issue occurs. If I put the macbook in sleep mode, and then wake it by clicking the external mouse, the display reappears normally and everything is fine.
The problem is when I am NOT connected to these external devices. The screen stays distorted (like it has lost its full color range) and there are other issues. The keyboard backlight seems to be disables and highlighting text does not work normally. I have tried rebooting, removing the battery and rebooting, resetting the SMC, removing recent applications (chrome, quicklook, etc.). Has anyone heard of or experienced this behavior?
Thanks.

Have you called Applecare? If you sent the machine in and it came back with a cracked case, that seems like an Apple repair to me.
As for the display issue - I think I would accept it and move on. Unfortunately, with these ever-higher resolution displays, we have more dead pixels. Since no one would pay $3000 for a display with 100% no dead pixel guarantee, Apple has to alot for a few dead pixels being acceptable inorder to keep prices reasonable.

Check with other vendors, this is common practice with LCDs (even HDTVs).

13" Macbook (black), Snow Leopard, Boot Camp, Windows 7 display issue

OK I don't know where to post this. I couldn't find an appropriate forum under Boot Camp (nothing for display). Apologies if this is the wrong forum.
I am attempting to run Windows 7 using Boot Camp. Here is the behavior:
Booting Windows 7 without any monitor plugged in works fine.
Booting with an external monitor plugged in, I get the display on the external monitor. Now when I unplug the external monitor, the LCD display backlight is off and is completely dim. I had to reboot it in order for the LCD display to work again.
This is not a macbook display issue. But it has to do something with the way Windows 7, BootCamp are compatible with a macbook. Anyone seen this or know what the fix is?
Thanks

I can not get my Win 7 (32) os to see my Mac 10.6 partition. Is there something I need to set or turn on to get this to work?
As for your problem, perhaps Windows is not seeing the FireWire bus?

New Macbook Air - display issues after waking from sleep

I have a 1 day old Macbook Air 13" (2013) --- when I wake the machine from sleep, the display shows horizontal / vertical bands for a couple of seconds before clearing up to show the desktop. Please see attached picture. This doesn't happen 100% of the time but I've been able to repeatedly replicate this at intervals. Does this seem like a hardware problem or an OS related issue? Thanks.

On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.

Since you just bought it, contact Apple about making an exchange within 14 days or repair after 2 week period.

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.

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:
http://web.mac.com/modoc1/iWeb/Site/30%20Inch.html
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!

Macbook Pro w/ Retina Display Issues with Wifi with Bluetooth.

I have a Macbook Pro with Retina Display, 2.3 Ghz model. I've noticed that while on wifi, when I use a bluetooth mouse or even turn on bluetooth on my computer, the wifi performance severely decreases for a short period of time. While using a bluetooth mouse the wifi intermittently fails and I need to shut off wifi and turn it back on to correct the issue.
Using the ping utility on terminal I have confirmed this in that when bluetooth is turned on, a large number of packets are lost for about ten seconds.
Has anyone else been experiencing this problem and is this an issue I can correct myself or should I contact Apple?
Thanks

I have the same issue with my macbook pro with retina display. I have 2 macbook pros. I never would of thought that a bluetooth signal was interfering with both of them. I had a gateway wireless router that only had 2.4 Ghz 802.11 b/g, which is the same frequency of bluetooth. I know that bluetooth bounces from channel to channel, whereas wifi sticks to one constant channel (normally). I have reinstalled my mac twice, thinking that somehow my drivers were corrupted. This was false becuase everytime I reinstalled it did the same thing, Act fine for 5-10 minutes and randomly the internet connection would freeze up all together for 10-20 seconds. I have also tried contacting apple multiple times and they tried to do a smc and pram reset. They also tried to get rid of my chaches in my computer. It all seemed to be fine, and then when I got off the phone it would act us once more.
     I have read numerous articles to try and fix the situation; one of them was to try change the location of the network and change the MTU size. No help. I called At&T (my internet provider) and got a new router and that did work for a while. But eventually acted up again. The router was still 2.4 GHz 802.11 b/g. I read this article and found out that my Magic Mouse might be causing the issue. Turns out to be true. Everytime I would browser the internet or browse the itunes store and it would freeze, i would immediatly turn the bluetooth off and what do you know, it works!!! This is a huge dissapointment in apple however. It seems to be only a macbook pro w/ retina display issue. My other macbook pro only acts up when i'm using my newer one (something is wrong with the bluetooth and wifi in the retina for the 2.4 ghz frequencies.
     I just got a Airport express, and have not experienced this issue what so ever. This is due to the fact that it is a dual band wireless router. It supports 2.4Ghz and 5 Ghz both at 802.11 a/b/g/n which is a major improvement compared to what I had. I use the 5Ghz frequency and have no issues still.
     This is still an issue however because if I want to go out and use anothers persons wifi, I can't control their frequency. So I will still have this issue.

MacBook Pro Startup and Display Issues

I've been having some random problems with my MacBook Pro (2.16 GHz, 2 GB RAM, 100 GB 7200 rpm hard drive, ATI Radeon X1600 graphics). Specifically:
1. Lines across the screen and purple boxes sometimes appear.
2. The graphic effects (e.g. zooming a window) sometimes get "frozen" on the screen. In other words a remnant from the animation will stay until the window is refreshed.
3. The Mac sometimes freezes during the startup process. Sometimes the login screen will be unresponsive and other times the Mac will almost bootup but fail when loading startup items.
4. Less frequently the Mac will freeze randomly. I previously had iStat Menus installed and each time the MacBook Pro froze up it indicated both read and write disk activities.
Yesterday I decided to wipe the machine clean and start from scratch in case there were a software issue or corruption on the hard drive that was causing my woes. I completely erased my hard drive and even zeroed the entire disk to make sure everything was completely wiped out. I also disconnected all peripherals to simplify things as much as possible.
The first time I tried the reinstall everything completed successfully but the "Welcome" movie froze part way through. I then had problems running the install again. I was able to boot off the Leopard DVD, but the machine froze a couple of clicks into the install procedure. After numerous tries I was able to erase the hard drive once again and install Leopard. This completed successfully and I installed all updates.
The problems started to show up again almost immediately, however. I installed iLife and iWork and all the updates and had the computer freeze up on me again during a reboot. I also noticed that the display issues started to show up again even before installing any third-party software.
I've tried running disk tests with Drive Genius 2.1, but no errors have been reported. I've also used the freeware Rember program to run memory tests but have yet to see any errors. Sometimes my Mac powers up without any problems and once it's powered up it often stays running for days. The display issues appear quite frequently. I've using iStat Menus to keep an eye on the temperature sensors and everything appears to be normal - so it doesn't appear to be temperature related.
Fortunately the computer's still covered under the extended AppleCare warranty, but I would like to have some idea what's going on before I take it in just in case they're not able to reproduce the issues.
Any suggestions and insights would be GREATLY appreciated. Thanks in advance for reading my rather long-winded message.
Cheers,
Tim

I took my MacBook Pro in for repair and it turned out to be an issue with the logic board. I had the logic board replaced (fortunately it was covered under my extended AppleCare warranty) and these problems are a thing of the past.

Display issues on mid 2009 Macbook Pro

I have had a recent intermittent display issue on my Macbook pro. It started a few months ago and is not a constant issue. External displays are fine so it seems to point to a connection between grahpics card and the 13" screen.
You can see an image of the problem here:
Does anyone have experience of similar issues?

i've done a complete rebuild back to 10.6.8 and found that both problems appear to have disappeared, both screen and TV working again since this morning without seeing any issues.
I'm now installing Lion to see if it returns.
the only difference will be that I'm not going to install bootcamp until later, this will be a clean install as before I installed Lion on a previous version of 10.6.8 with bootcamp etc already installed.
maybe this will work, wish me luck

Macbook Pro Early 2011 Display issue

Hi all,
After reading the replacement program that has been extended to MBP for 15" and 17", is there going to be any news with regards to the 13"?
The reason why I'm asking is that while I'm not sure if mine is an isolated issue or widespread/common occurrence, I have had my logic board replaced last year due to a display issue, and currently still unable to run external display, despite reading up on discussion that is going on.
The symptoms mirror that of the 15"/17", just that the 13" does not have a dedicated GPU.
Hope to get more suggestions/ solutions/ news to potential replacement program from here.
Thanks all!
Regards,
Ziang

Welcome to Apple Support Communities
Early 2011 15 and 17-inch MacBooks Pro have had several GPU issues that causes graphic corruption, and it was an issue that showed in most MacBooks Pro. However, this does not apply to the 13-inch MacBook Pro, so I think it is just an issue that has appeared on your Mac but there is not a reason for a replacement program.

MacBook on Order, Worried about display issues

I've got a 2.4 GHz MacBook on order (no returns since it's a custom build)and I'm getting a little freaked out after reading all of the posts about the display issues. Do you think this issue has been resolved on newly released models or am I going to be stuck with a machine with these issues as well?
Thanks!

From what I've been reading it sounds more like an issue with the video driver.
I've been so happy with my iMac, that I talked my wife into a MacBook, so if there are issues with it, I'll never hear the end of it. Plus it's no fun to get a new toy that's broken.
Guess I'll just have to wait and see if I have the problem others are experiencing.
I ordered with a larger hard drive and 4 GB of RAM. My employer has a discount, so I just upgraded when the order was placed. Most likely, to late to make any changes now.

Display issue with vertical windows start menu and dual screen

Hello everyone
I never reported it and I didn't find any information on google or mozilla support about this so here it is :
I am on windows 7 and I set up my windows start menu vertically. I also have 2 screens. These both points are important. If I put the start menu horizontally I do not have the issue anymore, and If I turn off one screen to have the display only on one screen, I do not have the issue anymore, which is a rare setup I guess so it could explain why this bug has never been detected.
HERE IS THE ISSUE
I have display issues on website with a big width, even the default add-ons Manager firefox page doesn't display correctly. Here is a screen shot:
http://img15.hostingpics.net/pics/368172bugFirefoxDisplay.png
So as you can see the disable and remove button on the right are not displayed, and at the bottom there isn't any scroll bar to scroll ! So I have no way to display the information on the right of the page, and it happens on a lot of other website (gmail, etc)
It is not such a big issue because my start menu is on my left screen and I can move firefox on the right screen to have a correct display.
I still think this is worth reporting this bug. I hope it is clear, feel free to ask questions if you didn't understand.

You can try to disable hardware acceleration in Firefox (you need to close and restart Firefox).

Black macbook backlight display issue

im working on a friends macbook. the issue is the display. the laptop boots up just fine but after laptop has powered up the screen stays dark. the battery is charged. when the "f2" is tapped once the display lights up a little. when pressed again it goes back to dim. i then have to press the "f1" key to bring down to the lowest setting. i do this all over again some times i can get to around the 3rd brightness setting then it automatically drops to dim. i assume the backlight bulb itself is ok so am i right in saying the inverter is going bad or is there something in the "f1" "f2" keys that is not making a good connection. I hope i explained this well enough. Thanks.

Actually, I don't think you can hook up the USB to a RGB cable.
Wich imputs does your projector support? VGA?
If your projector supports VGA imput you can use a displayport cable with VGA exit and plug the projector there.

Unibody Macbook Pro 17inch Display problems, vertical lines and artifacting

Hey everybody
I bought my 17inch MBP at B&H in June (week before WWDC, D'oh) and it was working fine until I came over to Ireland to work on a editing job for the summer, as soon as I attached it via mini display to a second monitor I started getting artifacts and vertical lines in certain shades and colours on the macbooks display, its gradually gotten worse so much so in fact that it is nearly unusable.
I have seen the thread about the firmware update, but my computer is already up to date with that but it still has this problem, I contacted apple and was told to take it to the apple store and the genius bar in Belfast, as helpful as the rep was he told me it would be two weeks for a repair, by replacing the logic board. Which I just can't do as I've only got three weeks left on the job and need my mac every day. I've searched and it seems no-one is having this problem except me since the firmware update, but clearly my machine still has problems.
Never had a problem with all my previous Mac's but I'm close to tossing this in the bin please help because if I can't get this solved I will have to move to PC and install my copy of AVID on it as this is the only other available computers at this production company.
What to do? Has anyone else had this problem recently? Or know of a fix for it? I've tried everything downloaded the firmware told me its already installed, switched the graphics displays etc etc
Please help
Thanks
Tom Lindsay

Welcome to Apple Discussions!
It sounds like there is a hardware problem of some sort with the graphics chips, and the only real fix is going to be to replace the logic board. So at some point, you will have to send your Mac off for repair.
In the US, you can sometimes arrange to get a loaner. You might ask if this would be possible where you are, since the repair is going to take so long.
Unfortunately, I don't know of anything that would fix your problem other than a repair.
Good luck!
