A verticle red line suddenly has appeared on my monitor

I was lookiing at a video on Youtube and tried to upload it. It didn't. But, suddenly now I have a verticle red line on my monitor which i cannot get rid of. Anyone out there have an idea what could be wrong? thanks.

Hi there camoroso2,
If the red line is still there, I would use these troublehsooting steps from the following article about troubleshooting your built in or external displays, named:
Apple computers: Troubleshooting issues with video on internal or external displays
Reset the system
You can reset the Mac's parameter RAM and SMC.
Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
Thank you for using Apple Support Communities.
Regards,
Sterling

I have a red illumiated dot has appeared,callers have told me i sound distant

Hi my daughters IPhone4 recent upgrade,A small red illuminated spot has appeared on the top menu bar????
Also when receiving calls she sounds miles away,volume low,any ideas why
Thanks
Paul

If the "Red Dot" is above the menu bar, left of the earspeaker, it is a glowing sensor. This is either normal or due to a slight power surge in the iPhone. Make an appointment with Apple Genius so they can take care of the iPhone's problems under Warranty Coverage.

Right Side Red Line will not appear for full browser width.

I had my top navigational bar set up to fill in a 100% browser width. Now, only the left side red line will appear and the right side will not work.

Any ideas on how to fix this?

Ah, I understand now. Menus will stretch to 100% browser width in terms of any background applied to the top level Menu widget, but the actual items will not be stretched or fitted at the moment. I'd recommend adding that to our ideas section so that others can vote on it. It would also help if you clarify what you'd expect. Would you want the menu items to grow, or the space between them? And what would you expect if one of the menu items became too long for the container? Should the text wrap, or should it not be able to get smaller than that?

Red line suddenly appears and doesn't go away

A thin red vertical line appears out-of-the-blue after running iTunes visualizer. Tried resetting p-ram and display settings - doesn't solve the problem. Does any one out there have a solution?

Hi Ohia,
I had the same problem. It just appeared as if from nowhere. I only discovered that someone else had the same thing when I went looking for a solution. I don't know if this will be any use to you but the line disappeared after changing the desktop picture several times. I have to confess that this was a purely accidental discovery. I also don't know if this will be a permanent solution. It may be worth a try (maybe you have already tried it).
Hope this may be of some help.
Cheers for now,

TS3276 Apple Mail Welcome Page suddenly has appeared

We had a blackout two nights ago now, and upon rebooting Apple Mail, it is now "Welcoming" me to set up my email accounts. They've been set up for 9 years. How do I get access back to Apple Mail? There are six separate email accounts.
I have read that I can move com.apple.mail.plist out of the Library and see if Apple mail rebuilds it. I also have time machine backups where I assume I could restore the mail.plist (and I assume one prior to the blackout as close as I can), but I don't want to go into time machine and drag com.apple.mail.plist into the library/prefs/ until I know I won't accidentally erase anything or emails.
Thanks for your advice in advance.

same here
icloud.com via safari won't let me access mail either
i think something must be wrong on apple's side

Mac has a vertical red line

My two year old macbook pro recently got a verticle red line. Its a complete strip of one pixel. I think it might be a stuck or dead pixel. I really need help. My mac isnt under warranty and i really dont want to spend money on repairing it. Are there any ways to remove it?

No. You need to have the LCD replaced. Single vertical lines of color do not go away.

Motion path red line missing?

Hey.
I've been using Motion 1.0.1 for about a year now and everything has been going great. Today I had my first problem. When I opened up motion and added the motion path behavior to one of my objects, the red line did not appear. I have played around with all sorts of view setting, window options, and looked though "Motion Help" as well. Nothing I have seen has worked. I just can't figure out how to get the red line to appear again so that I can edit it and continue with my project.
Thanks for any help!
-----prismi

Ok. I've managed to be able to find the red line. It only appears if these conditions are fulfilled:
1) I have done command slash to show the overlays
2) When I control-click on the object to which I am adding the motion path I select "transform"
3) My pointer tool must be the topmost transform/select tool (shift s)
With all these the red line appears, but I can not edit it in any way. If I change any setting the line disappears.

Sony 46" LCD Vert. Red Line on screen

I have a Sony 46" HDTV and have a Verticle Red Line from the top
of the screen to the Bottom.. Can this be fixed with an adjustment.
Can it be repaired. TV is 2 1/2 years old. Out of warranty.
Great Picture except for this problem. Thanks
Solved!
Go to Solution.

If it happens on all content and all sources (sat/cable/blu-ray/game/dvd/etc) it is likely a damaged transistor not allowing the red to shut off. Yes its repairable but at what cost I don't know you would have to get a estimate for that. Although I should add no matter what the actual cause is if its there all the time it will need to be serviced by a authorized repair technician.

Black has red lines and strange red color pattern in it!

I have an HP Touchsmart 520 - 1030 windows 7 all in one. When I turn on my computer and the Windows icon in the middle of the screen appears what should be a black backrground behind the icon is dark red. Once it boots up completely, everything black has a strange red lines and patterns in it.
Is there a fix for this?

Hi Lysa13,
You could try re-installing the graphics driver. If that doesn't work, it's possible the screen hardware could be starting to have problems.
Here is a link to the graphics driver:
http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=cp-98005-1&cc=us&dlc=en&lc=en&...=
If that doesn't work, you may want to try running a screen test in the hardware diagnostics. Here is a support document that explains how to do the tests:

A few seconds after render finishes, the red line re-appears above timeline.

Hello
I am editing a video consisting of still pictures (jpgs) on Premiere Pro CC 2014.
I am using dynamic link with After effects in order to add some animation effects on the still images (sky replacement, puppet, projection etc..)
After doing some work on AE, when I get back to Premiere, a red line appears above the timeline, meaning that I must render that clip (which was just worked on in AE)
Recently the performance while rendering became very slow (rendering inside Premiere by pressing "Enter" on the keyboard)
I just waited several hours for it to finish rendering a part of my clip. It finally finished.
I then played the video and it was running smoothly.
However, after a few seconds, without me doing any changes !!! suddenly the red line above the timeline reappeared.
And now, the video seems to be un-rendered, and it is either not playing or getting stuck all the time.
Does anyone have any idea what could be causing this?
This is extremely frustrating and looks like something is terribly wrong with Premiere.
screenshot is attached.
Thanks,
Tal

I have installed the xf86-video-intel-newest from AUR, but with modified version - 2.13.0. Now mouse pointer works.

Red line appearing along one border of a graphic (from Word)

Using: Acrobat 6.0 Professional (yes, I know it is downrev).
Source: MS Word 2003 for Windows.
Problem: A red line appears in the PDF that looks to be the invisible (right hand) border of a graphic that looks fine in Word. This occurs only on one of many graphics. We have tried converting the original image to PNG, TIFF and JPEG and all formats produce the same result. We have tried both printing to PDF and using the Distiller button that is in the Word interface. The problem persists.
Has anyone else ever seen this?

Just to clarify, in this particular case I get a white box, not gray. But I imagine it is the same thing -- an empty box. Also, I would like to mention at the top that I greatly appreciate your input and explanation, Aandi. Thank you. I have more questions, though!

Out of curiosity, which format does the EPS preview supply to Word? Word does understand TIFF, JPG, PNG, WMF and BMP (among others). You say that Word "ignores" this, but that sounds intentional. Rather, it is a format that Word doesn't understand or doesn't have the routine necessary to decode and display the preview. Any clue why? Not critical, but I'd like to understand the mechanics a bit more.

A preamble, then. Some information embedded at the head of each EPS file?
> These aren't drawing instructions, but definitions.
Definitions that define the parameters of the typeface, font, line weight etc. needed to create the drawing?
> After that, sometimes hundreds of KB, the drawing starts.
That is a LOT of instructions. A typical page of ASCII text takes up approximately 4KB of space. 1,275KB seems like an awful lot of instructions for a graph with only 20 words or so and perhaps 100 lines for cartesian coordinates. A "bitmapped" file of the same drawing takes up only a fraction of that, even uncompressed (TIFF or BMP for example, with JPG or PNG taking up far less than that, perhaps only 15 to 35KB in this case).
> When a PDF is made you are left with nothing
> but the drawing instructions.
I'm not arguing, just failing to understand the mechanics. Of course, I had two gigantic books on PostScript on my desk ten years ago and I never did read most of them...
Again, I thank you for your time and discussion, Aandi. Always helpful as usual, though I'm not sure I'd be comfortable trying to convey your description of the EPS-to-PDF process to others. If they asked a question, I'd be stuck!

Little red line appearing at bottom of 2 clips dropped onto my timeline

This isn't a clip that isn't yet rendered. Rather it's a line that appears at the bottom of the clip but only from the first frame till about half way through the length of the clip and it also has four little white rectangals at the start of the red line. It plays fine on the timeline, doesn't need rendering (if you do, it is still there) but I have never seen this before and wondered what the significance is or what it indicates?
thanks

it's showing you instances of using the same media in your sequence. you've enabled Show Duplicate Frames in the Timeline Options of your User Preferences.
time to get out the manual and read about your user interface.

My kid just got an iPod 5th gen (today from Santa) and it won't power up or charge. The only response is when I connect the USB and press the power button or front button the Battery appears with red line and lightning symbol. No other response at all.

Sorry about the long title.....its my first post.
My kid just got a brand new iPod 5th generation (today from Santa) and it won't power up or charge. The only response is when I connect the USB and press the power button or front button the Battery appears with red line on left and lightning symbol below. There is no other response at all no matter what I do, including holding both buttons down for extended period. My other kid got one and it works perfectly.....I have interchanged usb cables ports etc. but still no response....I would really appreciate any help.

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.
- Make an appointment at the Genius Bar of an Apple store since you have a hardware problem with the iPod. This is because as you said the same cable works with another iPod.

When opened, my image appears black with a few red lines at the top, yet the thumbnail looks as it should be. How do I fix this?

I have been working on an illustration in Photoshop for a few months now. When I tried to open it yesterday it came up as a single layered black image with a few red lines at the top. I have no idea what this is. I have not even used red in my artwork. However, no matter how many times open this file, the thumbnail still looks like my artwork, as it should be. How do I fix this? Will I be able to get my artwork back? Please help! Thank you in advance.

Make sure you has the latest Windows Device driver for your display adapted from its manufacturer's web site installed on your system. Perhaps you updated the device driver with a Microsoft Windows Update. Microsoft update does not always install the correct update needed fpr Phoroshop.
