Horizontal lines mostly in Safari

I found an archived post dating back to March 2008 with my exact issue. Here's a link to that post, which contains a picture of my exact problem. His was the Macbook Pro, but mine is imac intel (see below for the details of my machine).
http://discussions.apple.com/thread.jspa?threadID=1468905&tstart=
I'm trying not to be too upset due to the fact that my year warranty just ended in early December 2008 and I didn't purchase Applecare. Oh well, live and learn.
I'm just so surprised at all the issues I've been reading about in here. I really thought I was getting a great machine. My first mac.

Have you tried installing Fan Control?
http://www.derman.com/Download/Special/iMacFanControl.html
I was finding the same problems. Horizontal lines "frozen" into safari, itunes, and then eventually migrating to my destop and eventually whole sections of my desktop.
I tried everything to ensure I wasn't dealing with a bug (including a full wipe and rebuild of my mac (it had been a few years). So I wanted to be absolutely certain I didn't have a driver/software bug somewhere. And within about 4 hours of a freshly updated Leopard install, the lines showed up again.
I installed Fan Control, and I immediately heard the fan increase speed, and the next thing I noticed... no more funny lines. Guess my video card (NVIDIA GeForce 7300 GT) is not liking the heat in there.
Hope this helps.

Black horizontal line ipad mini Safari

New iPad mini appears to be having problems already. While using Safari in some websites, a fairly thin black horizontal line will appear typically in the middle of the page. It usually gravitates towards the spot where you try to read. Thin enough to kind of underline text for easier reading but big enough to be a nuisance. Is this a feature for easier reading in Safari or a bug.
Please help,

Michele,
I know this was mostly answered, but I am there with you. It's a very frustrating problem and you are not alone.
Merging the keyboard and splitting it again, as well as hard closing Safari, seemd to fix it, if only temporarily.
Slightly lifting the split keyboard from the bottom seems to completely solve this SEVERELY annoying and temper tantrum inducing problem. It has taken me more time than I'd like to admit to fix this, and I have my doubts that it will work permanently as well.
But anything that MIGHT work is better than dealing with this issue.
It may seem minor to some, but for a lot of us, it is very distracting and annoying.
I keep hoping with each and every update that it's fixed, and am disappointed each and every update.

My Safari is showing horizontal lines once in a while

I have a 15" MacBook Pro that's just over a year old. I started seeing horizontal lines in my safari window for a couple of months now. I have attached a screenshot below. Can anyone tell me what is causing this to happen? At first, I was seeing the very top of my Safari window flickering with thin colored lines. Now I am seeing what's attached below, probably once a day.
I want to know if something is wrong with my graphics card (which I don't think it is because it's only happening in Safari) or if something is wrong with my Safari.
Thanks!

Only happens in Safari ... I would try these steps:
go to Safari (in the menu bar), and select Reset Safari...
next, Safari / Preferences / Extensions and turn off the extensions.

30P weird Horizontal lines

I shoot with my DVX100a in 30p. Bring it in to Final Cut Pro 5, and export it as a quick time movie or an ipod video. The result is good other than the fact that I can see these weird horizontal lines, most visable on the border/perimeter of my subject and the background. They are very thin and sometimes cant be detected unless there is movement.
I know that people have this problem due to not doing any pull down or not editing in 23.98, but I'm talking about 30p, not 24p.

This can occur with 30P material if you do any moves on it, or speed changes IF you haven't set your timeline to Field Dominance: None. Are you SURE it's 30P? If so, is your sequence Field Dominance: None?

Faint horizontal lines accross iMac lcd

Had a 24" iMac that developed faint horizontal lines across the lcd that got progressively darker the longer the computer was on. Had the lcd replaced by Apple twice, but after a couple of weeks the problem returned. They gave me a new iMac, but a month in I have the same problem with the new machine. Has anyone encountered this problem? Is it an inherent issue with iMac lcds or is it something external affecting my machine? And I'm not talking poltergeist. Help, want this fixed.

We have a 20" imac Core Duo that was purchased summer 2006 - then about 5 or 6 months ago, it started developing horizontal lines across applications (Safari, Mail, etc) and the desktop - sometimes they would go away, sometimes not... I thought is was some video driver conflicting, upgraded to snow leopard, went to the genius bar, etc... but lately it got worse to the point that it started locking up every day... this after going weeks or months without a reboot and over 3 years having almost zero crashes...
I read in a forum where the video chip (GPU - graphics processing unit) was heat sensitive and thought that after 3+ years, maybe it was dusty in there... I installed the iStat widget to monitor the temp of the GPU and installed a fan control (software) where you can increase the minimum speed of the hard drive fan (allegedly located above the GPU). I also put the end of the vacuum on the fan vent just above where the power cord goes into the back of the monitor and let it run for a while hoping to clean things out...
5 days later - zero display issues, zero hangs and zero crashes - and the GPU runs an average of 25 degrees cooler than before. This after a genius bar guy told me that it probably needs a new display board. Good Luck!

Horizontal line safari

Over the weekend my safari browser started drawing a horizontal line about 5 spaces up from the bottom edge. Other apps don't have this line appearing on the screen. iOS 6.1.2 is my current rev level.....this is not a show stopper but annoying. Has anyone else have this extra line drawn at the bottom segment of the screen?

Give it to the school IT department to be fixed.

Text appears as horizontal lines on certain websites or not at all

I tried searching for this problem on the board but most people only have the text overlapping problem. When I go to certain websites such as Suntrust Bank or imaging-resource.com the text does not load in some of the menus and appears as only horizontal lines or not at all BUT the link is still there if you hover over it. This is the first time it happens to me. Maybe its the newest version of Safari that is bugged? I am running version 3.1.1.
Thanks,
Danny

Yes, but did you check your present IP, or the last one?
I'm also wondering if it could have anything to do iwth the fact that I have very big inboxes & sent mail boxes.
Not likely.
Wasn't sure if rebuilding my mailboxes might help - my mail program isn't finding files properly either.
Not likely to do with the sending problem, but...
Not certain, but this can fix myriad Mail problems...
Safe Boot from the HD, (holding Shift key down at bootup), it will try to repair your Disk Directory while the spinning radian is happening, so let it go, run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, then move this folder & file to the Desktop.
Move this Folder to the Desktop...
/Users/YourUserName/Library/Caches/Mail/
Move this file to the Desktop...
/Users/YourUserName/Library/Mail/Envelope Index
Reboot.
If that doesn't do it and you can afford to redo all your Rules, try these & reboot...
/Users/YourUserName/Library/Mail/MessageRules.plist
/Users/YourUserName/Library/Mail/MessageRules.plist.backup
Note, in 10.5 & up /Users/YourUserName/Library/Caches/Mail/ may or may not exist.

Intermittent horizontal line(s) appearing on screen

Greetings,
3 month old MBP
I'm getting horizontal line(s) showing up on the screen running the width of the open window. I've seen them mostly in Mail but also in Safari and Finder. The line is a pixel width thick. Sometimes it stops before reaching the edge of the window.
Any help / ideas would be greatly appreciated. I'm suspecting a hardware problem but it is a difficult one to diagnose / prove given it is hard to reproduce in a consistent manner.
Thanks,
Rod

I reinstalled Leopard from scratch to help eliminate software as the issue. After re-installation, there were still problems especially with graphics intensive apps. Returned the unit to my local Apple repair. They replaced the logic board under warranty and I have not seen the horizontal lines on the screen since then.

Horizontal lines on imac display, video card going bad?

I have horizontal lines and a triangular shaped artifact on my 24 inch Imac display. This happens after quite awhile of use, so I am thinking it might be the video card is about to go. Also, have issues with viewing flash videos, the browser (safari) will just quit responding, sometimes it will recover. Most times I have to reboot the machine. I believe all these syptoms are related. Any ideas?

Welcome to the Apple Support Communities
Your graphic card is damaged. Unfortunately, the only thing you can do is to take the Mac to an Apple Store or reseller to get the computer repaired.
Both problems may be related, because Flash uses the graphic card and it often fails

When I turn on messages, I can't see my messages. All I can see is a screen with horizontal lines and a text list of addresses. How can I get the regular message screen back?

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.

Toshiba 46G310U turns on for a few seconds the goes black with a horizontal line

I have a Toshiba 46G310U that when it is first plugged up it will come on for a few seconds and show a great beautiful picture, then the screen goes dark with a horizontal line across the screen that eventually fades out too. Turning the TV off and back on does not help, If I leave it unplugged for 5 minutes with the source unplugged also, it will come on when plugged back up for a few minutes at the most then starts the whole turning dark with the horizontal line that fades completely out. I've aready replaced the inverter board, the T-con board, and now I am at a stand still because I can find any help with the problem for starters(Toshiba Tech support was NO help and was unwilling to listen to my problem), second I am thinking possible power supply problem but I am having problems finding the power supply board, the main logic board, and the two small narrow boards that the T-con plugs into above the LCD display. Display has to be good for the picture to be perfect before fading to dark. Back light is also good as I can see it when the display goes dark it still has a glow and with the back of the TV off I can see the actual back light panel shinning. Suggestions? No I won't call tech support back as it was a horrible experience dealing with the rude techs. Thanks in advance.

The tech at Toshiba support was rude and seemed more interested in what was happening in the office then my issue with the TV. I've talked to a local tv service shop and they had no clue about the LCD type of tvs. I just would like to know if it is the main logic/input board or the power supply board. I can find the power board but have had no luck with the main board. Mr.. Moderator if you have any suggestions from Toshiba I would be very appreciative of your help. Thank y

Horizontal line - Running out of options.

Hi guys. I can hope someone can help
I have a LaserJet 100 MFP M175NW printer that is around 2 years old. I am getting 1 horizontal faded line right through every page I print, black, or colour. It is always in the same position
I have the exact same printer which is in perfect working order so I have tried the following
1: Used a new photoconductor I know works
2: Ran a clean cycle (10 times) on the cartridges
3: Installed 4 new cartridges, from the printer I know prints perfect
I'm not sure what else it could be? I am happy to get my hands dirty if there is something else I can try. I am thinking it must be some sort of dust/residue build up somewhere but I am not sure where or what to clean.
Look forward to your help
Picture attached showing the line I have referred to.

Hi @JSM87 ,
I see that you are getting a horizontal line in the same area when printing in color or black. I would be happy to help you.
Since you have already tried known good toners and a imaging drum, most likely it is the fuser or another hardware issue.
Please try the steps in this document to see if it will help resolve this issue. Steps provided are for running cleanings, calibrating the printer and printing off a Diagnostics Page and the Print Quality Page.

What were the results of the Diagnostics Page and the Print Quality Page?
Are you using Genuine HP Toner?

Hp 2711x Monitor: Flickering red horizontal lines, dots, shapes

I'm not sure if I have two seperate problems or if they are the same problem. But lately my monitor has many red horizontal lines or red dots, or random red shapes on screen that flicker slightly. They only appear on parts of the screen that are dsplaying either black or any dark colors. Any part of the screen displaying white will have no lines at all. The problem will go away temporarily if I shut off the monitor for a while.
Also before it begins doing this, and during, the entire screen will go bank for about 1-2 seconds and then come back. It never gives an error message when it is blank. I run a dual monitor set up with my laptop display and the monitor and the lines only appear on the monitor, not the laptop display.
I have the most current drivers for the monitor installed.
The computer is a Clevo W110ER with i7 3630QM 2.4 Ghz and a 2 GB video card, running Windows 8.

Hi Blue07,
What is the model number of the monitor.
I worked on behalf of HP.

My iphone 4s screen turned freaked out before my eyes, changing all different colours, now it is blue and black along the right side with horizontal lines, and is flickering. I DIDN'T DROP IT.

I was just sitting on the couch scrolling through facebook, I closed out of that and went to open safari, when it spazzed out, for a few mintutes it looked like LSD vision, it was all different colours and flickering the whole time. I turned it off and on again, and plugged it into my computer and now the right side is nearly completely blue, and bleeds to the left side with horizontal lines, and it is still flickering. I just finished paying the **** thing off. I thought I'd get another year out of it. I have taken exemplary care of it and it hasn't left the case since the day I bought it. I haven't dropped it, there was no warning for the screen to start doing this. So my question is, is there an easy fix (I am about to restore and update it, and I already played around with the screen brightness), and if not, am I going to have to pay for the screen to be replaced, because I don't have that kind money.

Probably sounded funnier in your head.
