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 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 lines across the screen of my Vision:M, need he

I have had my player since Janauaryexcuse me, February and have not had a single issue until today. I turned it on, and there are thin, horizontal, white lines running across the screen. They seem to be most intense over the text at the top left hand corner and if there is any text or picture in the main portion of the screen. I have no idea what has caused and what, if anything, I can do to fix this. I haven't dropped it, had it near any magnetic or other electronic devices, left it in excessi've heat or cold or... anything. I've been babying this thing and now the screen is barely readable when on. Anyone know what's up with this Will I have to return this for repairs Message Edited by appetencexx on 09-26-200709:02 PM

I bought one on December 24th 2006, didnt drop it or abuse it, after 4 months the same thing happened, I was out of luck because the 3 month labour warranty was up.
I was told by creative to mail it to their office at my own expense blah blah blah. A quick google search informs me it is a common problem and creative pretends it's your fault the unit has become useless, people also had horrible experiences with creative tech support, so after spending upwards of $400 already to purchase the Vision M 60GB, I decided I wasted enough money and time with this company and I now use the unit as a fancy 60GB portable hard drive.

What would cause a slim horizontal line across the screen of my iMac?

There is a slim line across the Center if the screen. It is horizontal. It does not appear every time I boot up, but it is causing concern.

Welcome to Apple Support Communities
It would mean that your display or GPU are starting to fail, most likely the GPU, as the line is not permanent. Does the line move during the time your iMac is turned on or change if you start up in safe mode (holding the Shift key while your Mac is starting)?
A good test you can do is to make a screenshot of the screen when your iMac is showing the line. To make the screenshot, press Command, Shift and 3 keys, and the screenshot will appear in the desktop. Double-click it and see if the line appears. If it appears, it's the GPU. If not, it's the display

Flickering horizontal lines across the screen

My Toshiba LCD TV has a thin black line going across the screen. TV is just a year old and is not under warranty. I've seen some comments that the LCD panel needs replacing. Is this my only option? Any other thoughts? Thanks.

Our Toshiba Regza Cinemax TV has been acting up, it has shadowing, sometimes horizontal and vertical lines. They are worst on the left side of screen. Anyone know what part may need to be replaced. This has been doing this for quite a while, it comes and goes. Paid almost $3,000 for this piece of crap it should have lasted more than five years.

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.

Help! N95 8GB Horizontal Lines on LCD Screen getti...

I was getting a few horizontal lines across my screen of my N95 8GB. Switching the slider from portrait to landscape doesn't change the direction of the lines.
The lines have been getting progressively thicker to the point where now it's hard to read anything on the phone.
Do I have a dying screen?
I've take the slider apart, detached and reattached the screen and ribbon cable connector, and it doesn't make any difference.
Should I buy a replacement screen or is there something else that could be wrong? The rest of the phone functions perfectly fine.
aloha,

Nokia N95 (A6.02)

Hi calciumicon,
It would probably be best to have your device checked by a Nokia Care point. From what you describe it might be the screen needs to be replace. The N95 is a model which has been out of production for a while though so check to verify it can still be repaired.

Red line across iMac screens

Both my sons have the 2006 white 24" iMacs and for the last few months the screens are showing an intermittent red thin horizontal line, not always all the way across the screen.
It can cause flickering when showing movies.
Also both have a tendency to lock up at odd intervals and require a hard restart.
Anyone else with the problem?
Peter

Louise,
If you go to the "Using your Intel-based iMac" discussion, you can find numerous posts about freezing/crashing 2006, 2007 vintage iMacs. My late-2006 iMac started to have these problems 3-4 months ago, and the problems increased in frequency over time. My 20" display also started to show partial horizontal lines at different times during this period. In my case my iMac eventually became so unstable it wouldn't run even 1 hour before freezing, and then would not re-boot successfully until I shut it off and waited for several hours.
I became convinced that heat was a major contributing factor for these problems even though the internal temperature sensors in my iMac were well within advertised tolerances. Rather than repeat what has been documented in the other forum, I suggest you read the recent thread:
http://discussions.apple.com/thread.jspa?messageID=10893244#10893244
The good news is that by taking the steps described in the referenced thread, my iMac appears to now be stable (knock on wood), and has run without a crash/freeze in 6+ days.
Good luck,
Dave

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!

Thanks a lot for your swift response. And sorry if it was a bit too hectic to go through my detailed query (which I did because it was misunderstood when I asked previously). As I've mentioned above, I was informed that updating to 5.0.1 would '''require''' me to '''delete''' the current version and then install the new one. And doing so will involve losing all my bookmarks. I guess I should have been more specific and detailed there. By losing, I didn't mean losing them forever. I'm aware that they're secured in some place and deleting and installing the software doesn't harm its existence. What I meant that if I install the new version, I'd have to delete the old one. And after installing the new version, I'd have to transfer them (bookmarks) back from wherever they are. Get it? When it updated from 3.6.9 to 3.6.13, and from 3.6.13 to 3.6.18, I didn't need to follow that process. They were already present on their own.
BTW, I'm having no problems with 3.6.18 but after learning about the existence of version 5.0.1, I'm a bit too eager to lay my hands over it.
Thanks for your help; hope this wasn't extremely long.

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.

I have a horizontal line across the middle of the ipod screen and the ipod and itunes won't sync. What is the line and is it connected to the no sync.

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

They are dotted lines across the screen horizontally.

When I upgrading to Lion Mountain, now I see somes "Drops" in the images. They are dotted lines across the screen horizontally. I reformatted and reinstalled OS 10.8.2, but the problem persists. I went to service, thought it was a video card problem, but it was not.

I have this too! I just bought this iMac a few months back. These screen are having a lot of troubles from what I am reading. My horizontal lines are not that bad, but you can notice them.
I might sell these computer off quick as apparently the quality of these screens is a nightmare.
