Strange Screen Glitches Starting Up

Sometimes when I power on my MacBook Pro, the screen is blank or has strange vertical lines in it. I think the LCD screen is bad. If you lightly press on the bottom corner of the screen, the problem usually goes away. If you lightly press on the bottom corner when it's fine, sometimes it will make the screen go blank and have the lines. Is this a known problem? I'm afraid to send it in for repair and have them not be able to reproduce the problem, as it only happens sometimes. I have included a link to a picture I took of the screen messed up.

Welcome to Apple Discussions!
There actually is a similar thread called "Strange Vertical Stripes" which you might want to look at, although your vertical stripes look different from the ones I saw posted last time I looked. But your issue could be related, as I think the others happened in the same way as yours did. This is a huge thread and you might want to take a look at it. There has been some thought that it might be fixable with a firmware update but I don't really know. You might run the extended version of the Apple Hardware Test to see if anything shows up--if you get an error code, that would be something very specific to tell Apple.
Good luck!

Strange screen "glitch," during start-up.

I am a little concerned about my brand new MBP, though everything else seems to be working fine.
When I start-up and the grey apple screen comes up, and the gear icon finishes spinning, as the screen switches to blue, there is a strange glitch. The screen flashes briefly, and the apple appears for a millisecond, offset an inch or so to the right, and then the start-up finishes normally.
There is also a similar "glitch,' when starting up in Vista on the MBP's bootcamp partition.
Windows starts up, but as the final screen loads after logging in, the screen flashes off/on very briefly before Vista finishes loading it's welcome folder, window.
Again, everything else seems to be working fine. Hardware tests show all is normal, no permissions errors, no disk utility repairs needed, and no problem files found with Diskwarrior.
I have also previously run an archive and install of Leopard, to deal with another earlier issue. Still the glitch...
Anyone else experience this, or have any answers.

i just experienced something similar. BRAND NEW MBP with tons of problems running leopard. my computer ran out of power completely last night because i forgot my power adaptor, so when i plugged it in this morning, and opened the case, i saw a totally gray screen that lasted for about 15 seconds, when it flashed into my desktop with all the applications i had opened when it lost power, HOWEVER, it was also grayed out with a strange meter (much like the ones that pop up for brightness or volume) filling slowing in white. After about 15 seconds of that, the screen un-grayed and looked normal EXCEPT for the top toolbar with the time, power, etc had a ton of tiny black glitchy lines through it and i couldn't see any of the information. the rainbow pinwheel was turning and turning forever and ever when that stopped and i was able to click on the desktop. at that time the glitchness disappeared and everything went back to "normal". Except for the fact that my keyboard stopped working! and i had to reboot. the black glitchy lines worry me.

Two days ago, I have a new iphone 4S. After I installed the OS and start the iphone, I found a strange screen says "!9D/JC" that blocks the iphone and I can not access the iphone until click many times on the "Desmiss" button at the botom of the screen.

I appreciate if you could provide me support to solve this problem especially it consumes the battery a lot.

Strange graphical glitch on 55TL515

I'm getting a strange graphical glitch occasionally on my 55TL515. When the glitch appears, it will reoccur every 20 seconds or so. I've discovered one way to make this disappear temporarily, but I'd like a permanent fix. Let me describe my living room setup for a second...
I currently have the TV connected by itself to one outlet. The second socket is currently empty.
In another outlet, I have a filled power bar plugged in. The power bar contains my stereo, xbox, pc, macbook, external hdd, and router.
When the glitch appears, if I unplug this power bar and reconnect it, the glitch disappears. I don't understand why this is. They aren't even in the same outlet (they used to be, until i started messing around with this problem). I've tested different HDMI cords, all of the HDMI inputs, and have seen this glitch when using both my pc and my xbox on this tv.
Can anyone provide a possible solution to this? I don't want to keep everything unplugged as I use them all frequently. Could it be the power bar? Is it actually a problem with the tv? Please take a look at this youtube video and see what you think. Thanks.

I get the same issue...typically this happens if I connect my laptop through a VGA cable. I've tried everything from changing my video card settings(resolution, refresh rate, etc...) but I get the same exact graphical glitch. Any luck on figuring this out?
Also, do you ever get thin lines that roll/move up the screen? I would get those occasionally and it had something to do with the digital switching inside the laptop power supply(the laptop power supply was on the same outlet) and was causing this problem so moving it to another power outlet or circuit breaker helped, but I still get the graphical glitch you have.

My Laptop freezes at startup with a strange screen

My MacBook Pro 2.4GHz A1226 will not start up.
It will turn on but a strange image seems to overlay the screen. I have uploaded a picture of it
http://tinypic.com/r/11ajyfr/7
[IMG]http://i53.tinypic.com/11ajyfr.jpg[/IMG]
It will get to a certain point of load up and freeze. The picture is taken at the freezing point.
In the past week the screen has started to flicker on and off a bit. I replaced the data cable in April of this year.
Any help would be greatly appreciated
Thanks

Hi rthomas63,
I saw your post about the blue screen of death (BSOD) that you are getting. I will be happy to assist but I will need more information then what you provided. What operating system are you running? What is your product number? What is the error that you are getting with the blue screen? When are you getting the error message? Do you get it at start up or when you are using a certain program. The more information you can post about the error message that better.
Find your product number on a notebook:

Screen glitch after update to 10.10.3

Hello ,
I'm experiencing screen glitch to my macbook pro mid 2012 13inch after updates to 10.10.3,
Please any suggestions

Screen saver starting even when disabled

Just today, my screen saver started to kick in after about 10 minutes of inactivity. The problem is, I've disabled the screen saver by setting it to "never." I've also set all of the energy saver prefs to "never."
Before today, the screen saver never started. What could be causing this? A corrupt prefs file?

The only thing I can think of is to make sure you don't have hot corners set in the screensaver preferences pane. If the screen saver just turns on randomly no matter where the mouse is, then that is really strange.

Iphone5 screen glitch after update to iOS 8.1.1

my iphone screen glitch after updating to iOS 8.1.1.

You need to be patient. There is no need to post again within minutes of the first post. Try force closing the App Store app and then reset the iPad.
In order to close apps, you have to drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the app that you want to close and then swipe "up" on the app preview thumbnail to close it.
Next, reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Leopard 10.5.5 Update - Freeze on Boot, Apps Freeze, Screen Glitches, etc..

After upgrading to Leopard 10.5.5 I've been experiencing MANY issues which I think are related to how 10.5.5 works with my video card (see below for system details):
If I shut my computer down it takes about 20 tries before it will boot completely without video glitches and freezing
Each time I start the computer it gets a little farther in the boot process before freezing
I have tried starting in Safe Mode but the computer never gets past the Apple logo and spinning wheel
I have tried Zapping the PRAM and this seems to help get a little farther in the startup process but doesn't do much else
All applications will freeze up randomly, giving me either a glitchy screen, spinning color wheel or both
If I ALTCMDESC during a application freeze, the Force Quit screen appears and the frozen program will work okay again (without me having to quit it)
Sometimes the computer will freeze and the screens will completely and flash different colors. This requires me to hold down the power button until shutdown
Repairing disk permissions gives the same error after every time I startup. As if every time I shut the computer down some disk permissions get messed up.
I have uploaded images of the screen glitches I have been getting as well as a text document with my Disk Permission Repair Report here
http://www.yousendit.com/transfer.php?action=batchdownload&batchid=Y2o4Y050dENYSHhjR0E9PQ
If anyone has experienced problems similar to these and has any suggestions on how to fix it without rolling back to 10.5.4 please share.
Thanks

Screen glitches and system crashes that still persist even while booted from the Install Disk points very strongly toward a hardware problem, even if AHT can't find it. Things to consider:
AHT asks that you disconnect non-essential pheriphals to run the test, & it doesn't test them. But you can just by removing them temporarily. (Note the the installer disk will boot the system even if no hard drive is installed.) Extend this to everything that can be removed without making the Mac Pro non-functional, including anything non-essential in its PCI slots.
Even though third party RAM is more suspect than Apple-supplied RAM, the latter can go bad as well. Try every combination of the minimum number of modules needed to run the OS on your Mac Pro to see what happens. You can also try extended RAM testing with Rember. You may also find the "Press" links at the Rember web site useful for more info about this, for example Troubleshooting Tools: Memtest and Remberfrom MacFixIt.
Physical inspection of the hardware sometimes also helps: are all cables & connectors (both internal & external) tight & in good condition? All covers in place & properly oriented? Any foreign objects lodged anywhere in the case, especially small bits of metal or other conductive substances? Mac Pro's are very cleanly designed inside as well as out, but it is still possible that the problem is caused by something like this.

Extended use of iSight (eg. Skype) makes screen glitch

Recently, my computer (2010 17" MBP, Snow Leopard) started having problems when I use the camera for ~1+ hour while Skyping. The other person will see me appear and disappear in rapid succession, then go dark (but the green dot stays on so the camera should still be functioning). On my end, the screen suddenly starts glitching and tiling pieces of windows around the screen. (see screenshot -- this was one Chrome window, one Gchat, and one Skype. All ended up appearing multiple times in various locations.)
Clicking on things has no visible effect. I can still get around using keyboard shortcuts (such as to save a document or close a window), but it won't affect what I see and I end up having to force-reboot the computer.
I've tried updating and reinstalling Skype, but I think the problem is with extended use of the camera itself rather than Skype.
I took my computer in to a help desk, but since the problem doesn't manifest unless you use the camera for an hour they didn't do anything about it.
Does anyone have any idea what to do about this? I haven't lost any documents yet but it's pretty inconvenient. Thanks!

Solved by upgrading to Mountain Lion. Not a hardware issue.

Screen glitching out

Hi, I just updated my laptop to 8.1 today, and after it taking about three hours or more to actually update, I found that the screen majorly glitches to the point where I am unable to click on anything. It will switch back and forth from my desktop screen
to a blue screen about every 2-5 seconds, and it is very annoying.
I was able to open up Internet Explorer by clicking on the icon right before the screen glitched, but I can still see it glitching behind the window. Also, I have no taskbar icons at the bottom of the screen, and if I move my cursor up to the top right corner,
no icons to search or open settings pop up. If I close out of Internet Explorer, the screen just starts glitching again, but this time with no icons so I have to restart the computer.
I am not sure what went wrong, but I just want this to be fixed so I can actually use my laptop. Right now I am not happy with 8.1.

Hi,
Did you run the Windows 8.1 Upgrade Assistant before upgrading? Did you see any incompatible information?
I would like to suggest you update all your drivers especially video card driver to check the result:
1.Right click start button and the click Device Manager.
2.On the Device manager windows, you will see a section called " Display adapter ", click on it.
Select one of the following:
3.Now right click on the video card shown and select " Update Driver Software ".
Or
4.To update the drivers manually, write down the name of the video card from the "Device manager" menu under "Display adapter". Go to the manufacturer's website, get the proper driver to install your own computer and
5.Restart the computer to take effect.

Screen Glitching on MBP OS X 10.10.3 (pic)

My screen has started to do this glitching thing occasionally. It happens in apps as well as just the desktop image. It is very intermittent. See picture. Of course my warranty ran out last month... but I am wondering if this is a big deal or just an annoyance? Here are my specs:
MacBook Pro (Retina, 15-inch, Late 2013)
Processor: 2.3 GHz Intel Core i7
Memory 16 GB 1600 MHz DDR3
Graphics NVIDIA GeForce GT 750M 2048 MB
I have the auto switching on for the graphics cards if that makes a difference... but can anyone offer some advice on what this is and is it a sign of a serious problem? Thanks!

@Mixitloud, I have installed from scratch OSX 10.10, applied 10.10.2 combo update to my Macbook Pro, and guess what: the annoying blink bar gone. I didn't install 10.10.3 yet, I need some more time, I think I can do this tonigh.
jennifer31416, thanks for your post.. but.. my Macbook Pro isn't a Retina model. But can help Mixitloud.
BUT.. there is light at end tunnel!!!!

Weird Screen Glitch/Freezing

I tried searching but nothing came up. So my macbook has done this weird thing where the screen would start glitching up and then it will freeze. 1st instance where it did this was when i set it down on the table and it did it. When it happens it will show blue bars in squares and the screen will go all loopy and return to normal for a bit and do it all over again. The 2nd time I did it was during the middle of an update and the macbook was sitting still. The 3rd time was a moment ago and now I'm deciding to ask about it. I was just typing on my lap and it did it. This time however I tapped the right side of the keyboard in annoyance and noticed it got aggravated when I did it. Meaning it would get loopy when I tapped the board. So I was thinking something may be up with the HDD and maybe a loose wiring?
I plan on taking it by apple but is there any thoughts or maybe fixes that do not require me going by Apple store? Thanks in advance!

Not that you should ever smack your macbook around.....
however in doing so you likely indicated a bad monitor cable or same at the logic connector. If it is actually so that blue bars and squares vanished upon tapping it, this would (if correct as per your description) indicate not a bad GPU rather the cable to monitor or connector for same @ logic.
nothing you indicate has anything to do with the hard drive however.

Droid 2 global home screen glitching?

I recieved my first droid 2 global and after about an hour of using it, the home screen would start flipping to another screen about every 2 seconds. And it would always be the last thing I selected. For example, if I was looking at my contacts and hit the "home" icon, it would go to the home screen for a few seconds and then flip back to my contacts and continue doing this everytime I selected "home." It would also not let me get to the app screen at all.
I did run a virus scan, nothing came up and I didn't download a single app. About all I did was set up facebook for android and add a few contacts.
I took it to a verizon store and the man there had no idea what it was, so after putzing with my phone for an hour including doing a factory reset, he said they'd send me a new one.
BUT I had the same problem with the second phone and I'm completely frustrated and clueless. Anyone have any insight?
[removed unnecessary links]

ATT: NANCE, YOU SAID IT. I MEAN, YOU REALLY DID HIT IT RIGHT ON THE HEAD!!! "
My Droid x2 locks me out of my own phone, while in the middle of a text or phone call it just decides to lock itself.
Unlocking my phone is a pain because the touch screen glitches as I try to draw in my lock pattern.
My phone started muting itself on/off numerous times during a phone call with my boss >:(
If I am lucky enough to get my phone unlocked and get to my home screen sometimes it begins selecting apps
or m contacts or the dialer and then freezes.
It restarts maybe 2-3 times a day. The one time I drop it (it started doing this after it fell off my lap as I stood up from sitting at a restaurant.)
And finally just about a week ago it began to start deleting my own contacts..
I loved this phone until it decided to run itself? I Still likr it though,

Something strange when archlinux start up

Hi,
I have something strange when archlinux starts up.
At the beginning, the resolution of screen is the same with the resolution setting in menu.list of GRUB. Then after the prompt "bring up lookback interface OK", the screen splashes one time, then the resolution of screen changes to a higher one.
Anybody has encountered this problems?
Thanks

Thank you. It works
