Grey lines / shades on the screen

Hi,
I have really strange problem with display in my iPhone 4s. Only in some applications and on some parts of screen there are visible strange grey lines/shades. Did you ever experience something like that? Is it software or rather hardware problem? Thank you in advance.

What kind of problems did the ebay seller mentioned in his posting ? this is significant because he may have already diagnosed the problems.
If he is a reputable seller and he did not accurately stated the issues described in your posting, you could demand your money back.
Depending on what and how he described the condition of the PB you may also have a good reason to contact ebay.
Overall and from your description it sounds like your PB has serious issues and you may not be able to repair it yourself. One thing that you do not want to do is to attempt to replace the screen yourself ; I have done it and I can promise you that I will not do it again. On the other hand it could be a problem with the video card.

it is possible that zoom maybe enabled i think double taping with three fingers should disable it.
or you can go into settings>general> assessability> zoom and turn it off.

I updated my iMac to 10.7.3 and about an hour later the screen began to flicker with a gray line on the upper side, and it also flicker green and red small pixel lines all over the screen, mainly green.

I updated my iMac to 10.7.3 and about an hour later the screen began to flicker with a gray line on the upper side, and it also flicker green and red small pixel lines all over the screen, mainly green. The computer froze with these pixels, so I shut it off and restarted it, and there were this green lines everywere. So I turned it off, and the next day I turned it on and it began to work just fine, but suddenly the same thing happened again, and when I restart the computer again there are these green and some red pixels everywere.
I've read 10.7.3 is giving people many problems, but I never saw that it gave one like this. How can I fix this, or what will Apple do to fix this problem they caused me with their update.
Thanks

Contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine.

Ipad had colored lines running through the screen

My ipad first generation which i love now has colored lines running through the screen. Can it be fixed?

Howdy diana,
It sounds like your iPad has mulitcolored lines all over it. I would recommend a few things here to help isolate the issue to software or hardware. Try restarting the phone with this article:
iOS: Turning off and on (restarting) and resetting
http://support.apple.com/kb/ht1430
If the issue persists, I would next try reseting the device with the same article:
To reset, press and hold both the Sleep/Wake and Home buttons for at least 10 seconds, until you see the Apple logo.
If the issue is not resolved, I would next backup your device to iTunes, and restore it as a new device to see if the lines are still there. If not then restore your backup and verify they are still gone.

If the lines are there even when setup as a new device, your iPad may need service:

Laptop suddenly had horizontal lines running across the screen

Suddeenly horizontal lines appreared across the screen .
I have shut down and started up the computer numerous times and it does not go away .
It also affects the graphics and text on the screen .
If I cannot fix should I have the computer cleaned and set back to factory standard and how do i do that /
Thanks

2 possibilities:
1. The video chip (motherboard) has gone bad; or,
2. Just the screen has gone bad.
Connect the computer to an external monitor and see if the lines appear on it. If so, it is #1.
It is doubtful that restoring the laptop to factory specs will have any effect on the isue either way but if you want to do that you can tap F11 as you power up to enter factory reset.

I purchased Macbook Pro i5 in March 2011. Now the screen has problem; one vertical blue line is in the screen (at the right side). I noticed this last week when I opened the MacBook, and now I am always seeing it. How to remove it?

I purchased Macbook Pro i5 in March 2011. Now the screen has problem; one vertical blue line is in the screen (at the right side). I noticed this last week when I opened the macbook and now I am always seening it. I am seeing the blue vertical line always in the screen. However, I am not seeing this line when I open Word, Excel, PowerPoint files (without pictures). But I am seeing this line always when I see movies, pictures, and all the files which have pictures. Please do let me know how can I remove this vertical blue line (blue tint) pernamentally from the screen.

Backup your files to a external hard drive and disconnect.
Call Apple and make a warranty call, then take it to the nearest Apple Store etc.
You can run these things and it might clear your issue or give further informaiton
Perform a hardware check

Then see if resetting the SMC/PRAM resolve your issue

My ipad 1st gen has loads of coloured lines going across the screen so I can't see any ideas ?

Try a reset: Press and hold both Sleep/Wake and Home buttons until the Apple logo appears.
If that didn't fix things, do a restore:

If that still didn't fix the issue, then there is probably a hardware problem.

Satellite M65-S9063 - Vertical white lines appearing down the screen!

Hi all - any ideas...
Model M65-S9063 Approximately 3 weeks ago a vertical white line appeared down the screen, it's around a mil thick.
Then yesterday a second one has appeared, slightly thinner this time. They're always there even after a reboot! It doesn't look as though any video is being displayed as they're always white. I was wondering graphics card perhaps? Or maybe the LCD itself?
Anyone seen this before??
Many thanks,

Hi!
You can simply determine the reason of this issue. Connect an external monitor the notebook and see what happens.
If you can notice the same error on the external screen, its a problem of the graphic card or display driver. If you dont have this issue on the external screen, you should go to an authorized service provider for exchanging the internal screen.
If you use a non Toshiba display driver you should remove it and test it with original Toshiba drivers.
I hope I could help you a little bit.
Bye

My mac screen comes out with white fuzzy lines going across the screen, it used to just go back to normal and out of no where it freezes and the white fuzzy lines go across the screen. Now it is frozen at the opening screen. what do i do?

My mac screen is frozen with white fuzzy lines going across the screen. I shut it off and turn it back on but it still remains white fish lines on the start up screen. I've tried revolting it, it works sometimes but now its stuck at the starting screen. I have been at this for 2 hours to try and fix it but nothing has changed about the screen. What do I do, if I break this computer I'm screwed.

I would post a picture of the screen but I do not know how to do that

Extra line running through the screen on my Officejet 6500 printer

I just noticed a second horizontal line running through the screen on my Officejet 6500 printer screen (right through where the ink levels show up.) The screen resembles graph paper. What causes this? Is there something wrong with the machine? Can something be done to correct it?

Hi there,
A full factory reset may not be required. Try downloading and running the print and scan doctor located here:
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c03275041&cc=us&dlc=en&lc=en
It can fix a lot on its own and if not give a better idea of what is going on.
Best of Luck!

Why are there lines going across the screen?

Why are there lines going across the screen?

It may (likely) be a video card issue. There is a "known issue" with certain iMacs made in a certain timeframe (2011-12 I think), and one of the telltale symptoms is vertical lines showing up on your display. Go to Apple's website (https://getsupport.apple.com/) to find out how to get support, then either call their service line (they usually pick right up) or take it into your nearest store's Genius Bar. They'll first check if your iMac's serial number is on the list of vulnerable machines, and then they'll have to do a diagnostic to prove that's the problem -- if your serial number's on the list and it fails the diagnostic, they'll replace the video card for free, even if you're not covered by AppleCare (and if you are, it's free regardless).
My iMac just had this problem, there were lines sometimes and just weird display issues other times. Eventually it just grayed out altogether and I couldn't use it. So it's likely your display problems will worsen if you don't get it looked at.
It took them about a week to ship the new video card over, install it, and return the iMac to me.
Good luck!

40 inch Samsung LCD White Horizontal lines running up the screen constantly

My brand new Samsung 40 inch tv (purchased in mid-December) has white horizontal lines running up the screen constantly. From what I heard, the electricity in my house my not be grounded, but no other tv in my house does this, so I doubt this is the case. Has anybody else had this issue and is it too late to return the tv? Thanks.

Does it do it on other sources like a DVD? If so you may have a TV problem. Have you tried to do a factory reset or restore? Have you tried plugging it into an outlet in a different part of the house? As a last resort have you tried taking it back to the store and see if it works there? Also have you tried a filter on the AC plud in? Just some suggestions to try and help you out.

When i unplugg my ipod lines appear across the screen and wont turn on how come?

when i unplugg my ipod lines appear across the screen and wont turn on how come?

Is it working properly when it is connected to power?
when i unplugg my ipod lines appear across the screen and wont turn on
Please clarify... Does the screen look "normal" (and is it turned "on") when connected? When you disconnect it, "lines appear across the screen"? If it "wont turn on," how are there lines (or anything) appearing on the screen?

Gorilla glass has never been claimed to be scratchproof. Resistant, but not "proof". I am afraid there is little you can do about it but pay for a screen replacement or out of warranty replacement phone from Apple.
