Screen Distortion (Horizontal lines) Across Display

For quite some time now my Macbook display has had horizontal lines along the right side of it. These lines go from the very top to the bottom and are about an inch or two in width. Sometimes goes away when i have a Pages document open. But is constantly there otherwise.
I have attached a link to a picture to better show the problem.

If you have already had a case number with Apple for this issue and it is not resolved, you ought to be able to have it serviced. Call AppleCare and reference the old case number, and explain that the first fix did not fix the problem, and because you brought this to Apple's attention before your warranty expired, they should still do the repair for free.
You can test for whether it is faulty RAM by pulling out one stick at a time and testing whether the lines persist.
Good luck!

Horizontal Lines Across Display

Hello Everyone. I just recently purchased an iPod Nano 8GB Green Engraved and I love it. The only thing that bothers me is that when the brightness level is at 45% and up the display has Horizontal lines dancing across the display. It does NOT hinder the viewing of the iPod and I am extremely sensitive so many people might probably notice it. I am wondering if anybody else experiences this issue and if this is left alone, will there be any future problems with it? I don't want to replace it as it was engraved. Thank You very much for your help!

Hello Deggie. Thank You very much for the help. I think I will just leave it alone, because as I said it does not hinder the use of the product and also I am very sensitive to things like that, so I am probably one of the very few who would notice it.
Thank You Deggie

Notebook dv7t. Red transparent horizontal lines across entire screen.

I need to know if it's as bad as I suspect. 2-1/2 yr old notebook dv7t on Win 7, with 17.2" monitor. No error messages. Troubleshooting finds nothing. Never had any problems before. All day yesterday, Tuesday 8/19, rebooting and shutting down repeatedly without success. Today, nothing, no lines!. Gotta expect it to happen again. No update available for NVidia GeForce card. Can anyone please advise? Thank you. Sillenn

I have a horizontal line across the bottom of my screen how do I remove it?

Re: Macbook Air mid 2011, I have a horizontal line across the bottom of my screen, it appeared when I was updating my iPhone, How can I remove this line from my display?

It may be a GPU or display issue. In both cases, make a backup of your Mac and take it to an Apple Store or reseller to get it repaired.
To check whether it is a GPU or display issue, try taking a screenshot by pressing Command, Shift and 3 keys. The screenshot will appear in the Desktop, so open it and check if the line appears in the screenshot too. If so, it is a GPU issue; if not, it is a display issue.

HT2807 why is there a horizontal line across my imac screen?

why is there a horizontal line across my imac screen?

Not sure exactly which model your iMac is..?
see > How to identify iMac models
Sadly display lines generally indicate a problem with either the Display or the Graphic's Chip.
To check, take a screen shot of the display using the (Command Shift 3) keys and open it.
If the line is only seen on the Display and not in a screen shot, then it would most likely indicate a Display problem.
If the line shows up in a screen shot, then it would most likely indicate a Graphic's Ciip problem.

Horizontal Lines Across MBP Display

I am getting horizontal lines across the display of my laptop. The lines do not show-up when I have the computer attached to the external cinema display, and the lines will go away if I run the disk utility, with the only errors being SUID errors that cannot be repaired, and Apple has said aren't an issue. However, the next time I open my laptop, the lines re-appear. I've reset the PRAM, and that didn't work. If the lines are showing, a rebooting of the system does not help. The only fix I've found is running disk utility, but that is a very temporary fix.
The lines are all over the screen rotating up from top to bottom, and multi-colored. The overall display is blurry.
Any ideas?
Thanks,
Will

Unfortunately, that makes it sound like a problem with the built in display. Have you tried running the extended version of the Apple Hardware test? If you get an error code, it might give you a clue.
Do you have access to an Apple Store? I think they have a special diagnostic for the NVIDIA chip problem, so they might be able to pin down for certain if the problem is with the chip or the display.
Good luck!

Thin Horizontal Line Across Screen

I've had them before and they disappeared spontaneosly. The latest one seems to want to hang around. Any idea how to get rid of it?

This is a followup to my post earlier today. A web search on "Thin Horizontal Line Across Screen" turned up this article:
http://www.daniweb.com/techtalkforums/post24947-5.html
Sure enough, my horizontal line came back. I decided to follow the advice in the linked article. I didn't even have to twist the monitor. I barely tapped the screen as I was reaching up to twist the panel, and the line disappeared. This suggests to me that the problem is a loose internal connection between the driver circuitry and the panel.

Hey Dean Marvin,
Thanks for the question. These two symptoms are probablyh related. To troubleshoot, let's try resetting your iPod:

I have a straight horizontal line across my screen

Hi Folks
have a straight horizontal line across my screen. Can assist?

Yes, move the screen slowly back and forth, if it changes, you have a damaged monitor feed cable
Does it appear in all screens?
Does it vanish from time to time?
post a pic, hook your AIr up to an external monitor, if its there, its GPU /logic problem
if its gone, its as mentioned a bad monitor feed from the logic via the cable.
perform SMC reset and re-verify
SMC reset
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
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.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
Contact Apple for an appt. for in shop diagnostics and likely repair.

Horizontal line across the monitor. It happened yesterday.

I have a HP ENVY 23-c1 10xt AiO (Lavaca3-SB)PCUS and there is a horizontal line across the monitor. It happened yesterday.

Hello again javajohn23,
I would like you to try the following steps:
Step 1. Turn off the computer, and then remove the power cord
Step 2. With the power cord disconnected, press and hold the power button for five seconds
Step 3. Reconnect the power cord, and then turn on the computer
If the above steps do not resolve it try the next set up steps:
Step 1. Restart your computer
Step 2. Repeatedly press the F10 key about once every second for five seconds after turning the computer on
Step 3. Wait five seconds
Step 4. Press the F5 key. This restores the default settings of the BIOS
Step 5. Press the Enter key. This accepts the changes
Step 6. Press the F10 key. This opens the Save and Exit window
Step 7. Press the Enter key. This saves the changes, exits the BIOS, and then the computer restarts
Step 8. Restart the computer.
Another thing I can think to try is review the HP Support document: Changing Display Settings, Background Image, Icons, and Screen Saver (Windows 7) to see if you can identify anything out of place.
We can also try to reload the Intel Graphics Driver for your computer as it will wipe out the settings when the new driver is reinstalled.
Please re-post with the results of these steps. Thank you for posting on the HP Forums. Have a great day!

Weird horizontal line across my macbook air 11"

It's been 2 days my Macbook Air 11" (bought on 2011) started to display an horizontal line across the screen. It gets dark when the background is light and it gets light when the bg is dark. I tried to get a screenshot but it doesn't show the line.
Do you have any idea of what it is? I bought this macbook while I lived in USA but now I'm back in Brazil. Any suggestions?
Thank you.

Start Up Screen Freeze With Lines Across Screen

The computer is the iSight version. In moving it from one room to another I shut it down properly. I had a back-up HD with Time Machine which I shut down properly. When I tried to restart it shortly after at the new location, the start up chime sounded and the Apple logo came on with the spinning wheel but the screen had light blue horizontal lines across it. The lines at first seemed squiggly but after restarting a few times, the screen seemed to be divided into vertical columns about 3/4" wide with one column having pixels colored light blue and the next column having the same coloration but the row of colored pixels was above the previous one. This arrangement alternated across the screen. I hope this is clear. After a while the spinning wheel and the screen froze and the computer would not continue with the start up.
I reset the SMU by unplugging the power cord, etc. but this did not work. I tried restarting in safe mode-negative. I tried restarting from the original disc-negative. Initially, it sounded like the disc was working because it makes a distinctive noise when a disc is working in the drive but eventually the same initial screen came on with the wheel spinning and then freezing. I tried the current versions of Techtool Pro and Disc Warrior and neither worked. The same thing happened. The noise from the disc drive but the same screen would come on and then the spinning wheel would freeze. Initially the screen with the Apple and the spinning wheel and the lines came on quickly but after a number of times turning the computer on and off, the screen remained dark with a faint light and when the screen came up, the spinning wheel was already frozen.
I use a flight simulator-X-Plane- a lot and some times when I leave it on, screen saver comes on and when I bring the screen back up, the first screen that came up and quickly changed had to do with X-Plane but not with what I was doing. Also, sometimes when I left it and came back there was a different screen but still part of X-Plane but not the screen I left before. I don't know if this is related to my problem or specific with X-Plane. I brought it up because this is the only thing that was different prior to this problem but may not be related. Right now, I've turned it off(obviously) and disconnected the power cord and the keyboard.
Any help would be appreciated.

I've started taking the iSight apart. Detaching the plastic took some time and care but with only a few tears. Separated the screen. The main board is positioned such that the capacitors are on the bottom. So many connections and most of them small. Have to be careful. So many small screws. I hope I can remember where they all go when I put everything together-I hope. I'm at the point where I've turned the main board over so that the capacitors are showing. I hope I can reconnect correctly. Two capacitors have a slight bulge at the top compared to the others. Although I am not sure whether these two are part of the problem. There is another one that has no bulge but there seems to be some stuff on the top. It is not corrosion so I'm not sure whether it was manufactured that way or something is wrong with it. I finally found the battery. Just to change it is such a job. You have to disconnect a lot of stuff and turn the board over to get at it unless Apple technicians have a shortcut. Do you think the battery could cause the problems I have? Anyway, if I have the board exposed already might as well try and change the capacitors. I have not come across any video that shows how to expose the underbelly of the main board. Nor have I seen any video that shows what each part is. On the left side of the layout is an long rectangular shape covered over with black plastic. I haven't checked it out but I assume it is the power source. At the upper left there is a rectangular board with capacitors underneath but there are connections underneath that are so tightly stuffed that I couldn't turn it over but I could lift it up a little and see the heads of some capacitors and there wasn't any bulging capacitors or corrosion. There's one big capacitors under there. Much bigger then those on the mother board. Interesting observation. When I turned the screen over to expose its back most of it was frosted except for a small rectangular piece that was dark but glassy like and the glass like part lies exactly on the small rectangular board about 4X5 or 4X6. Interesting why this small section of the back of the screen should be different from the rest of the back and why it should be exactly above the smaller board. Like the previous versions of iMac, it would be so easy to be able to open the back and have all of the capacitors exposed. My next action is to contact one of the references you posted and see if I can get these three capacitors and the battery from Radio Shack or somewhere and solder the capacitors to the mother board. After all of this putting the whole thing together correctly without ending up with extra parts. One thing did break. Next to the fan in the middle there is a piece of metal attached to the back. There is a small narrow slot in this metal that another piece of bent metal seems to go into and was soldered to it and when everything is put together it seems, although I'm not sure, that this metal touches the back of the screen. It looks like I have to solder it back. I don't know what its purpose is, maybe it grounds the screen? I thought the piece of metal was something to pull in order to liftup something else. So far that is the only thing that has broken and hopefully can be easily fixed. But nothing that seems easy is easy.

My 1st generation Ipod touch won't turn on at all and whenever I press the buttons to reset it all I get is a white screen, or a white screen with black lines across.

You can work through the five 5 R's of troubleshooting to rule out the possibility of corrupted software.
http://www.apple.com/support/ipod/five_rs/
It might also be a good idea to let the iPod's battery fully drain. Then charge it back up and restore it once more in iTunes.
Otherwise, it's likely a hardware issue with the iPod's LCD display, meaning you'll need to take or send your iPod in for service either via Apple or a third party repair service. Here is Apple's repair pricing.
http://www.apple.com/support/ipod/service/prices/
Note that they don't actually repair the device, but exchange it for one of the same generation, model, and capacity. A third party service will actually replace the damaged part for a little less. Google "iPod screen repair" and you should get a number of results to work with.

The same is happening for me. Today I decided to reboot my PC because it was acting up a bit, go figure, and then for some reason at the same time the PC was restarting my macbook froze. I had to do a reboot with the restart button but then all that came up was a gray background and in the middle of the screen was a darker gray folder with a white question mark in the middle of it, blinking. I can't imagine why the restart would've affected my macbook. After finding information on how to fix this, I tried all of the steps that were given about using the mac OS X disk to use the first aid utility to fix it. When using the Disk Utility option whenever I select my hardrive and am in the First Aid tab, the only button I can use is the Verify Disk Permissions. The other three buttons, and namely the most important Repair Disk button, is/are not selectable (grayed out). I then tried resetting the PRAM the way they also said with the command + option + P + R and waited for the second startup sound. After that I gave the Disk Utility a second try, but still nothing. And now if I try to just reinstall the OS completely I can't even select a destination volume on the third step (Select Destination). Apparently this means i'm SOL.
