My new iPhone 5 has black and white lines on the screen. It's not been damaged. I've tried turning it off but this does not solve the problem? Please help.

My new iPhone 5 has black and white lines on the screen. It's not been damaged. I've tried turning it off but this does not solve the problem? Please help. I can't find my answer on the Internet.

By far the most common problem hardware-wise seems to be scuffs on the aluminium. Yours is the first report of a faulty screen I've seen.
If you use the same Apple ID on both devices it'll sync whatever you want it to - music/apps/photos/messages/etc.
I've just switched from a Galaxy S3 to iPhone 5 (having already owned an iPad for a while) so I'm in a similar position!

Has anyone else has seen this problem with their iPod touch 5th Generation with iOS 7.0.4. My screen started making flashing white lines across the screen, then went dim, then pixeled with purples

The ipod will show flashing white lines across the screen, going down, it then does somthing where the screen will dim down but its not like when the backlight goes on and its about to lock. It dims the background of your ipod and the icons and letters kind of all look defined. Then the ipod gets all pixelized and it has big boxes on pixels and its all differnt colors like purples and greens, red, etc. then it turns right off and restarts itself less than 5 seconds later. These things happen really fast but when it does it's really weird. It first happened 3 times in a row, Its still continuing to happen but i can manually turn off my ipod by holding the lock button down and not even 30 seconds later it's like its possessed and it turns on by itself. I talked to somone on appel and they told me to back it up and restore it. I restored it and as soon as the process ended and tuirned on like a brand new ipod and like clockwork the glitch happened instantly. It did it a couple of times throughout the night and i kept having to watch it so i can keep turning it off manually because it continues to turn on by itself. I talked to 3 different people on Apple Support and they couldnt even find an answer for me. It's so weird.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Also,
If you restored to factory settings/new iPod via iTunes (Not via Settings>General>Reset>Erase all Content and Setting) and still have the problem that indicates a hardware problem.

I have an iphone 4 and i'm having lot of problems:
_ my back camera is blurred although my front camera is fine and working normally
_ my biggest problem is that the screen is showing colored horizontal lines(as perhaps electrical problems). The phone did fell and I already changed its back and front but everything was normal until these problems appeared suddenly
Please can somebody help me to solve it and tell me what are the reasons?
Thx

you can try turning it off and on again, but i doubt that's gonna work, that sounds like more of a hardware issue. Your best bet may be to contact apple and seek service or replacement

Pixel problem? Lines on the screen

hello my iMac is 3 1/2 years old. about 6 months ago I started to get lines on the screen, last week one of the lines turned into an 1 1/2 inch white line. From what I'm reading it's a pixel problem. My question is should I have this problem repaired, or is it not worth doing. thank you.

Are the newer versions less apt to have this problem. and is there a history of this problem with iMacs thanks.
Tough questions, the problem is that iMacs are sort of All-In-Ones, using basically Laptop components with a Desktop Monitor & Hard Drive, if one thing goes you can't just replace say the Video Card like on a PowerMac or MacPro, because most everything is built into the Logic Board.
I strongly suggest that anyone getting an iMac or Laptop go for the extended AppleCare.
As for the new iMacs, they look really sweet, but I myself would not buy one with an nVidia Graphic Card, I'd have to order the more expensive ATI Graphic Card.

I create a project w/iMovie and I have two problems: When I try to finalize the project iMovie crashes; when I share to DVD sometimes it crashes also; if I can successfully send it to DVD and then burn a DVD there are wavy lines on the screen. Help!

I create a project w/iMovie and I have two problems: When I try to finalize the project iMovie crashes; when I share to DVD sometimes it crashes also; if I can successfully send it to DVD and then burn a DVD there are wavy lines on the screen. I'm uising photos in my project, not video. Help!

You can split a project in two by doing this.
1) Go to the Project Library View.
2) Select your project, and click FILE/DUPLICATE PROJECT. Give it a name like "your project name - part 1".
3) Do this again. This time name it "your project name - part 2"
4) Open Part 1 for editing. Delete everything in the second half.
5) Open Part 1 for editing. Delete everything in the first half of the project.
At the end you should have your original project, plus the same project in two parts.

My phone switches off after showing horizontal lines on the screen during the restore process and then shows the error 9 problem. please help i am so stressed.

Hello
My iphone 4S switches off after showing horizontal lines on the screen cutting through the apple logo during the restore process and then right after my iTunes shows the error 9 message, this happened 2 days ago when my phone just switched off unexpectedily and has been in this recovery mode since then. i have watched videos on Youtube and i have disabled Firewall before starting the process, i think i have done almost everything. please help anyone what do i do from here?
Just for interest sake i watched this video on youtube where this guy had the same problem but the difference is that he had it on an iPad. he opened the ipad up and did something on the ipad, it took less than a minute then his ipad worked.
I would appreciate it if someone would respond to this as fast as they can i am so stressed.

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,

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 )

Issues with lines across the screen, as well as freezing

Issues with lines across the screen, as well as freezing
Hello all
Got an iMac since January 2008 and I do like it a lot, even though it has some issues:
-- It displays (quite often) lines partially across the screen
-- Lines appear as well when opening applications or when menus come up
-- The system freezes more than I like to admit (more than my Windows/Ubuntu box)
I don't know if the freezing has to do with the lines that are shown on my screen. But I assume that both issues relate to some video card problem. I can't be sure - but that's what I assume from living with this issue day to day.
The line on the desktop (most of the time it is there before login) I can always get rid of by changing the display resolution to something else and then changing it back. Normally the line is gone, or, reappears on a different spot on the desktop. But repeating the procedure removes the line.
However, this does not mean that the lines are not showing up again when launching apps or displaying menus!
And since those lines appear to happen randomly, I think it's safe to assume that we're not talking dead pixels here, either...
About the freezing:
My iMac freezes sometimes when I move the mouse around, when switching desktops using "spaces" or when the zoom function of the Dock kicks in. Sometimes the screen goes completely black, sometimes completely white. The mouse, however, always works. But the system requires a reboot.
Again, this happens too often to feel comfy about it.
With my little knowledge of Mac troubleshooting I assume that there's something wrong with the ATI card that's built into my Mac. On the other hand, some people say that they started getting similar issues after updating their OS to Leopard. Again other people say that such issues stem from an ATI revision that is too old and the Mac should get a new ATI card. And how would that work? Isn't that an "all-in-one" machine with everything soldered onto the mainboard?
So, any help in this matter is greatly appreciated...
Cheers,
Rainer

Here are a few screen photos I've taken (not screenshots, as the lines are not visible when taking screenshots. I used my digicam to snap those...).
Here's the link to those screen photos displaying some of the many lines I keep having:

HT1430 Ipod touch (5th generation) w/ lines across the screen - now dead.

My son's Ipod touch (5th generation) had lines across the screen. I turned it off using the home + on/off button reset, but the apple never came back on. Now it seems to be dead. Not dropped, not completely drained, no water damage. Just dead. Any ideas?
I have also tried plugging it into my Macbook Pro, and iTunes does not find it.
ITunes is up to date.

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: 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. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

My MacPro 10.6.8 has a thin green line on the screen.

My MacPro is just over a year old now and I have a thin green line on the screen. I hooked it up to my TV and on the second window (the TV) the green line wasn't there. Whats the issue? How do I fix it?

From what you are saying, sounds like a line of pixels out on the display.
Did the TV use the same connector on the computer? If not, swap the display with the TV. If you still have the line, it is one of the items that you swapped across.
Have you tried connecting the display to another computer? If so, is the line still there?
What kind of display is it? Can you swap the data cable and try a different cable, could be a cable issue.
Any adapters in use? If so, try swapping those to rule them out as a problem.
Did the TV use the same connector on the computer? If not, swap the display with the TV. If you still have the line, it is one of the items that you swapped across.

T400s vertical line down the screen - outside of warranty

Hi
I've had a T400s for just a 2 bit over 2 years now and was always happy with it. I used it mostly with my docking station and have never travelled with it. Now out of the blue one day half the screen was black with a few pixel problems right in the middle with a clear vertical line down the screen. I was perplexed because I was sure no damage whatsoever happened to the notebook.
I googled and it seems to be a common problem:
A link among others:
"We have about 1200 T400s systems deployed and there has been a higher than normal failure rate with them compared to X301 and T61 systems. Our issues are LCD failure with a vertical line down the screen (very common), Speaker/Audio issues, and DoA systems."
http://forum.thinkpads.com/viewtopic.php?f=45&t=89101
The problem seems to be known:
http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-76367
But since the notebook is outside of warranty but it's obviously a manufacturing problem on a (very) expensive notebook, how could I approach Lenovo service center to repair it for me? I have shelled out well over 2'500 Euro for the latest model back then and am a bit disappointed to be honest..
Thanks for any advice on how to approach this!

@tripplec, i don't understand how a Chinese company affects the outcome of the OP's problem? Would IBM do it differently?
Yes, I spent 3 years at a Toronto Bank who bought say 500 systems or so plus notebooks. ThinkPad's and Think Center product. I supported did the warranty work while there. When the warranty was up it was up!! Even if a lowly optical mouse fail and a number of them did. Too bad nor replacement.
I've delt with IBM, Compaq and HP. There customer relations is entirely at at different level and would and did on may occasions provide one time post warranty repair even for catestophic issues well after warranty was over. This is a case by case basis. You could reach them and talk to them (locally) and not haveway around the world having no sense of what significance your case it.
There is a difference as was the turn around time 48hrs max and not weeks.

Hi
The majority of issues with lines appear to require a new screen or the ribbon connector between the screen and the board is loose. These could be caused by mis-treatment although not always and I'm sure you would have mentioned if you had dropped the BB. So it does seem likely that this app has caused the problem.
Uninstalling doesn't completely remove an app from the device, hence why it makes no difference. Before sending the device away for service (or fixing a new screen yourself) it will be worth wiping the device and reinstalling the OS. I would be tempted not to reload the problem app, there has been comment on here about the benefits - use the search facility above right if you are interested.
