Mackbook Pro display has flashing bar

The 15-inch display on my MacBook Pro 5,1 has a vertical bar near the center of the screen, with fabric-like patterns, and it is flashing rapidly.Shutting down and restarting will eliminate the disturbance for a short time.
I recently installed a new 750 GB internal drive from OWC Macsales, but it appears to be working fine. I have never seen this symptom before.
I am able to run applications, but the flashing bar is extremey distracting.
The computer is out of warranty.
I will be grateful for any advice, recommendations, or cures.
Thanks.

Mende1, thanks for the tip. I scheduled an Apple Store genius appointment for today, then cancelled because the problem disappeared. It's a 120-mile round trip; so I wouldn't want to waste it if there's no evidence of the problem or what may have caused it.
If the graphics card needs to be replaced, I'd like some idea of the cost. I Googled the card specification wirthout finding a match from any Internet seller. Other cards ranged in prices from $400 - $2,000. The only reference on Apple's website is a $200 upgrade option on new MacBook Pros.
Here's the card currently installed:
2.3GHz Quad-core Intel Core i7, NVIDIA GeForce GT 650M with 512MB GDDR5 memory
Thanks.

Laserjet pro m1530 has black bar at top when copying

Laserjet pro m1530 has black bar at top when copying, scanning bar seems to stick and not reset at top. Turning copier off seems to reset the screen back to top but next copy has same problem. No problem when printing from computer.

Have you tried connecting the print to a different wall outlet or location?
if no please try it and if it doesnt resolve then contact HP Tech support on 1 800 474 6836 and they will asist you further.

Albook G4 Display Has White Bar Bottom Screen

Hello all:
My Albook G4 display has a white bar on the bottom third of the screen. Last year I followed these steps to fix tighten the hinges: http://macintoshhowto.com/hardware/how-to-fix-a-loose-hinge-on-an-aluminium-powe rbook.html
and I'm guessing I may have damaged, loosend or otherwise screwed up the connections. Any suggestions? TIA!

Thanks for your reply. Not quite sure when the issue started (my daughter's machine) but I think its been progressing for several months.
Before your reply, I was thinking hardware (monitor cable) but at your suggestion I ran TechTools - no issues. I also checked and repaired permissions, ran the fsck -fy in single user mode, and changed the desktop picture and screen saver options. It seemed to have cleared up, but when I adjust the screen position (open or close) the same area briefly acts up. I still think it may be a connector or cable issue, but there obviously was some sort of software issues too, so thanks for your suggestion. Is there a tutorial on how to check the screen connections that you would recommend? Thanks again!

How do I back up data from My iPad 2 to My Mackbook pro, that has a new HDD installed in it.

Hi guys,
I have an ipad2 with some home movies that I had transferred from my 2011 mackbook pro.
The HDD of my macbook had a mechanical failure recently so I had to get a new one installed but obviously lost some home movies and familly photos.
Now, I have some of that data on my ipad2 but but everytime I connect it to my mackbook, it wants to delete the previous data on my ipad2.
Is there any way that I can transfer those home movies from my ipad2 to my mackbook without deleting it?
And if that is not possible then how can I transfer data/movies etc from my macbook to ipad2 without deleting the existing one on the ipad?
P.S. They are both on the same wifi network and I have maverick OS on mac and iOS7 on the ipad.

It is a very easy thing to do. If you bought the apps with your Apple ID you can always download them again for free - using that same ID - in the purchased tab of the App Store. If you bought the apps, you can keep them all.
What I would do is ... Before you give her the old iPad, transfer all purchases into iTunes on your computer, backup your iPad with iTunes and sync one last time. Then when you get your new iPad, restore form the old iPad backup and sync with iTunes and the new iPad should be identical to the old one.

Macbook Pro Display has a pink tint to it

Ever since I upgrade to 10.6 my display has been wiggin out on me. Half the screen usually has this pink tint to it. Sometimes it's only 2-3 inches across but goes to the top and bottom. Don't know what's going on with my display. Is it due to heat? Cause my laptop still gets freaking hot. I have done a hardware test and passed. When I connect it to another display, it doesn't show up on the other monitor. I can grab the top of the monitor and by pressing gently I can make it go away, but as soon as I release it goes back. I used to be able to press on it and it would go away for awhile. Any suggestions?

I am encountering the same problem with my MBP. I was wondering if you have any updated information on what you have found out?

My Mac Book Pro display has turned purple/blue, - why?

My screen started to flickr and has now turned purply/blue as if something has died..any one know why?

Your first choice is to go to System Preferences>Displays>Color. Make sure that your profile set is the appropriate one for the MacBook Pro, which should be "Color LCD".
I'm going to skip all of the normal suggestions of resetting this and that, because from what I've researched this in the past, and it appears you have an issue with either the graphics chip (low probability) or a worn cable causing one of the color channels to be bad or your LED screen has a problem.
In other words, it's probably hardware related.

Macbook Pro display has no picture after I turn it on

I am running 10.6.7 on a MacBook Pro (15-inch Early 2008). The machine was fine this morning and an hour later, I booted it up and the screen remains dark.
The light on the front of the machine shows that it is on. The battery is charged and the laptop is plugged in.
I have tried the following and with all the screen remains dark
-- booting from the Install Disc to run a disk Utlity
-- Connecting to my iMac via Firewire to boot up as an external drive
-- Resetting the PRAM
-- Resetting the SMC
For all, I dont really hear any startup noises and definitely no mac tone on startup. The only indicationt that the machine is on is the light at the front.
I am out of warrenty... Any help?

Hi Lisa, is it sleeping, or not starting at all? Any noise at power up?

My 2010 Macbook Pro display is distorted upon startup and I can't login or see apple icon/progress bar. How do I go about fixing it? Thanks.

I have a 17" MAcbook Pro purchased late 2010. Recently has developed some display problems, y'day ran in safe mode and it fixed it and I was able to login etc., This morning when I boot up, it shows display distorted and I can't see apple logo or progress bar etc., and am unable ot login. I need to atleast be able to recover my files before I give it for fixing (if it needs to be repaired). Any steps you folks recommend for me to run? Any diagnostics or other tips? If I run safe mode, it seems to hang after a while and it is hard to read the screen to know exactly where it is stuck.....as the display has problems.
Thanks for your help.

there is an app called daisydisk on mac app store which will help you see exactly where the memory is focused and consumed try using that app and see which folders are using more memory

My macbook pro's screen display has suddenly gone into a strange colour setting where everything appears in a kind of infrared colour palette an I can;t seem to change it back. It's the same for all icon and websites, does anyone know how to restore?

Wow! I think I had this same issue just last night.
I was cleaning my macbook pro retina on the outside. Then I opened it up and was wiping dust off the monitor and I can't pinpoint exactly when, but the colors changed suddenly. It looked super strange, it was like green halo's and it looked worse when looking at it at an angle. Of course I took no pictures!!! I was freaking out that my 2 grand laptop was busted and I somehow removed a protective film or something.
But I digress... The image looked very green and spacey, it was almost a neat effect. After about 5 minutes it started to look a little more digital though. There were straight lines of this halo effect on the edges and top. After about 10 minutes it turned into a predominate issue with the blacks on screen. I could open a web browser and it was unnoticable on a white background. After about 15 minutes, you could only barely see the green cloud effect if you looked at the monitor from an extreme angle. After about 20 minutes, it was completely back to normal, I almost feel paranoid like I see a halo or something strange. But I believe that might be all in my head now.
So yerp, lemme know what you guys figure out.

Go to System Preferences>Displays and set the resolution to "Best for this computer" (or something to that effect).

HT4061 Does iPad MIni with Retina Display 128 GB Wi-Fi Cellular has Flash Light ?

Does iPad MIni with Retina Display 128 GB Wi-Fi Cellular has Flash Light ?

No, it does not. There are some apps which will turn the screen white so you can use that as a flashlight, but it does not have an LED camera flash.

My Mac Pro (2006) has suddenly stopped sending signal to the display monitor.

My Mac Pro (2006) has suddenly stopped sending signal to the display monitor. It coincided with plugging in an Epson printer via usb - while the system was running. Pretty dumb maybe? Could I have damaged the video card? Anyone ideas? Thanks

Howdy Le Batch,
I was looking into the issue you are seeing here, and came across a helpful article for this specific situation. It's named Apple computers: Troubleshooting issues with video on internal or external displays and can be found here:
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
If more than one video adapter is in use—or "daisy-chained"—troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the system
You can reset the Mac's parameter RAM and SMC.Reset the resolutionStart by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
Regards,
Sterling

My macbook pro says Shockwave Flash plug-in has crashed pretty much every day. I have to shut the computer down and restart it. Is there anything I can do to stop this from happening?

Download the latest version from here ONLY:
http://get.adobe.com/flashplayer/
also, make certain your Mac OS X software is completely up-to-date. There is a Trojan Horse that pretended to be a Flash update, and installed Flash with malware included. The latest security updates removes the malware and all older versions.

Hi. I am not able to update the Adobe Flash Player on my MackBook Pro. The problem I am getting is a blank page for Step3. Can someone help please?

If you already have an older version of Flash Player, open the Preference pane and select Check Now... under the Update portion under the General tab:
You shouldn't have to install a new version from the website (I'm not even sure if you can) if you've already installed Flash Player.
