Flat panel white line

I have an Imac bought less than two years ago. This morning when i turned on my computer i found a white line around 4cm in the middle of my screen. What should i do? Should i change the flat panel? Is it normal for apple product to have a quality issue like that after 18 months?
Thanks for your advices

If your iPod Touch, iPhone, or iPad is Broken
Apple does not fix iDevices. Instead, they exchange yours for a refurbished or new replacement depending upon the age of your device and refurbished inventories. On rare occasions when there are no longer refurbished units for your older model, they may replace it with the next newer model.
ATTN: Beginning July 2013 Apple Stores are now equipped to do screen repairs/replacements in-house on iPhone 5s. In some cases while you wait. According to Apple this is the beginning of equipping Apple Stores with the resources needed to do most repairs for iPhones, iPads, and iPod Touches that would not require major replacements. Later in the year the services may be extended as Apple Stores become equipped and staffed with the proper repair expertise. So, if you need a screen repaired or a broken screen replaced or have your stuck Home button fixed, call your local Apple Store to see if they are now doing these in-house.
You may take your device to an Apple retailer for help or you may call Customer Service and arrange to send your device to Apple:

White horizontal lines on 15" flat panel G4

I have white horizontal lines running across the screen of my 15" flat panel G4 i-mac (2003).
This first happened 1.5 years ago, when my apartment flooded and there was a lot of humidity in the room. The problem disappeared after a day or so.
Until now, it has only recurred once, and disappeared after a day. This time, however, the problem has persisted for a week; I have not left the computer on for longer than 5 minutes at a time since. I have not performed diagnostics of any kind, and am hesitant to play with hardware.
I would definitely appreciate any tips or suggestions.
TIA -
Jennifer

Hi Jennifer,
It is possible that you have a bit of crud on the motherboard (which is causing the graphics card circuitry to act up). This may be as a result of your earlier episode.
Given that getting to it on an iMac is a fairly involved task, as well as cleaning it, I would take it to an appropriate service centre and see whether they can give it a clean and get it working that way.
Cheers!

Blue thin line on the lower left iMac G4 Flat Panel

Hi, since yesterday there is a blue thin line (0,039 inches (1 mm) thin; 35 inches (9 cm) long on the panel of my iMac G4 Flat Panel. It looks like drawing with a ruler, so straight and so fine.
The line is on the left lower corner in a vertical position. At first I thought these are dead pixels, but I checked this. No dead pixels. I have changed the desktop picture etc., but it`s all the same. I run the apple hardware-test cd - no problems found. Is there someone with any idea? Is it possible to have a damaged graphics- chip although the hardware-test is o.k.?
Does it make sense to open the iMac and look for dust and dirt on the motherboard?
Thank you for any help, Matse

What happens if you change the
display resolution? (Apple Menu > System
Preferences... > Displays > Display tab >
Resolutions) If the line stays in exactly the same
place despite the resolution change this points to an
LCD rather than graphics card issue.
mrtotes
thank you Adam for that hint. The line stays exactly in the same place. That means it is an LCD issue? That´s your opinion? Do you have any idea if it is possible to repair it, or is the only possibility to change the panel?
Thank you, Matse

Sleep causes vertical lines on G4 iMac (Flat Panel)

Hi.
I've installed Leopard on my Flat Panel iMac and everything seems fine - except that I cannot use the sleep function.
As soon as I enter sleep mode (timed or manual), the screen is filled with vertical lines before sleeping.
When I wake it up, even more lines appear, filling the screen completely. Though, keyboard commands etc. still work fine. Only the screen output is affected. The only solution I found is a hard reset and disabling sleep mode...
Does anyone have the same problem - and even better - found a solution?
Thanks,
Phillip

I've had exactly the same issue with a 17" Flat Panel iMac, 800Mhz. I would be interested if anyone comes up with a solution.

IMac G4 flat panel update

just got a 17" iMac flat panel, the moderne white one with the ball bottom.
It's running system 9 right now, it did not come with any disks.
what steps would I need to take to get it updated as far as it is possible to go?
how many systems disks would I have to go buy and go thru? I have a tiger update disk but that's about all I have.

Leopard is no longer available at the Apple Store but may be available by calling Apple Phone Sales @ 1-800-MY-APPLE (1-800-692-7753).
If you can't obtain a retail install DVD from Apple, look on eBay or Google the installer part numbers to possibly find at an on-line store. Here's what to look for:
MB427Z/A Leopard 10.5.1 install DVD
MB576Z/A Leopard 10.5.4 install DVD
MB021Z/A Leopard 10.5.6 install DVD (single user)
MB022Z/A Leopard 10.5.6 install DVD (5-user family pack)

IMac 17" G4 (Flat Panel) - Which Airport Card

I have an iMac 17" G4 Flat Panel computer. The processor is 1.0 Ghz. I looked up on Apple's site which card it takes. This link is a bit confusing. It says the iMac G4 17" Flat Panel uses an original AirPort card, but then the next line says iMac 17" 1 Ghz uses an AirPort Extreme Card.
Here is the link...
http://docs.info.apple.com/article.html?artnum=86258
Anyone know for sure?

Hello and Welcome to Apple Discussions.
If your processor speed is ≥1GHz then you have the correct card (Airport Extreme). If your iMac is ≤800MHz then you need the original Airport card.
Make sure you have the card inserted fully in to the slot.
let us know how you get on.

I need help with imac g4 flat panel download of leopard it tells me it cannot load on the system.

i bought a refurbished imac g4 flat panel. it is supposed to have an os but it only comes up with a question mark. I put leopard in and it tells me it cannot load on this compuert. system is 800mhz and 60g hd and 768ram. i have tried to do a fix through the utility and it says it does not exit and kicks me out. ANY HELP IS A PLUS.

Try holding down the option key then power on. This brings up the startup manager. Click on your hd. Click on right arrow key.
Sometimes if volumes don't appear in Startup Manager (what you get when you hold down the Option key at startup), you need to reset the Mac's PRAM, NVRAM, and Open Firmware. Shut down the Mac, then power it up, and before the screen lights up, quickly hold down the Command, Option, P, and R keys, until the Mac has chimed twice more after the powerup chime. Then, before the screen lights up, hold down Command-Option-O-F until the Open Firmware screen appears. Then enter these lines, pressing Return after each one:
reset-nvram
set-defaults
reset-all
"The reset-all command should restart your Mac. If so, you have successfully reset the Open Firmware settings."
http://support.apple.com/kb/TS1812?viewlocale=en_US
You have got get in open firmware to hack the mhz to be higher for the install. That is change what the machine reports as the mhz to be a higher number. Details:
http://lowendmac.com/osx/leopard/openfirmware.html

This works on Tiger but I assume it would work on Leoard.

I tend to think dashboard is neat, but not neccesary for my everyday workflow.
it is possible to enable and disable it as needed,
by entering the following commands into the terminal:
-- To turn Dashboard off:
defaults write com.apple.dashboard mcx-disabled -boolean YES
-- To turn Dashboard on:
defaults write com.apple.dashboard mcx-disabled -boolean NO
-- You have to restart the Dock after making either change for it to take effect:
killall Dock

Viewing a pdf in Firefox browser has white lines. How can I fix the problem?

Viewing a pdf document in the FireFox browser (other browsers the document is fine) shows white lines though the pictures. I have tried different ways to save the document (printing or save as) as a pdf and I either get white lines or missing content while viewing on Firefox.

Please update to the latest version of Firefox.
*[[Update Firefox to the latest version]]
Also make sure that your graphics card drivers and WebGl drivers are up to date
*[[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Which pdf viewer are you using?
In order to change the default reader for PDF files (to not open PDF files with Firefox's internal PDF reader), follow these steps:
#Click the menu button [[Image:New Fx Menu]] and click Options (Preferences for Linux and Mac).
#In the Options (Preferences for Linux and Mac) window, select the ''Applications'' panel.
#In the ''Search'' field, type ''PDF''. You should find ''Portable Document Format (PDF)''.
#On the right hand side you should find an ''Action'' column. Use that to select your favorite PDF reader. In order to view PDF files in Firefox, choose ''Preview in Firefox''.
Did this fix your problems? Please report back to us!
Thank you.

How do I get rid of an ugly white line around areas of type?

Hello InDesign forum,
Attached is a screenshot of a pdf file I created of a brochure I designed.
Actually, it's just one panel of that brochure. In that panel there are unsightly white lines that appear around areas of type.
I have yet to find a way to get rid of them, and I'm not sure what causes them.
The brochure started out as an InDesign CS5 file and then I converted it to a .pdf file so it would be print-ready for PSPrint, Alpha Graphics, or a similar printing facility.
Any advice you can share about what is causing these lines, and how to get rid of them, would be very helpful and much appreciated. Thanks!

It is one of two things. Either the frames actually have a stroke applied to them, or they have some sort of transparency effect and you are flattening the transparency in the PDF and these are transparency flattening artifacts called "stitching." From the screen capture it looks as if it might even be both -- stroked frames onthe white type at the top, and stitching around the yellow type.
If it's a stroke, set the stroke color to [None]. To eliminate stitching export to Acrobat 5 or higher compatibilty to keep the transparency live. Stitching doesn't usually show up in press output, but it may in lower-resolution digital prints.

White lines in InDesign CS6

I'm using ID CS6 on a mac with OS 10.7.4 (Lion). I want to draw a white line. I'm using either the pen tool or the line tool and clicking on the "paper" swatch in the swatches palette to color the stroke white. The line immediately disappears. It doesn't matter how thick I make the line. If I click on a text box, choose "stroke" and "paper" for the stroke color, I get a white line around the text box. Picking other colors creates a visible line with the chosen stroke color. Only the "paper" swatch makes my stroke disappear.

Hey c….. thanks for asking for the screen shot of the panels. As I studied them for awhile before taking the shot, I noticed that I have the effects set to "multiply" instead of "normal" !!!
Stupid, but I probably would never have caught it if you hadn't asked to see my panels. Thanks!!!!!

White lines in 3d text

I'm new to illustrator so this might be a very simple/obvious problem to fix.
I have text that I have extruded. Unfortunately, the resulting text has white lines throughout it. (I've attached a picture).
My understanding is that Object > Expand Appearance has something to do with resolving this problem. Unfortunately, I am unclear as to what role this function plays (I've clicked Expand Appearance and it does not appear to change anything).
It would be greatly appreciated if someone could clarify how I go about fixing this problem.
Thanks in advance.

Expand appearance turns live efffects into paths. This causes lots of objects to appear positioned side by side. The lines appear because of antialiasing. In this simple graphic you could use the pathfinder (from the pf-panel) "Merge". Then the lines should be gone.

White lines around transparent gifs

I've tried without success to eliminate the thin white line
that appears around my transparent gifs in Fireworks. Does anyone
know how to achieve this?

The problem is how GIFs render transparency. What might help
is to change the "matte" color found in the Optimize panel. It's
probably set to white. Set it to match the background color of
wherever the GIF is going to go.
Because GIFs can't have semi-transparency, then anti-aliased
(smoothed) edges basically have to have a background color baked
into those pixels, that's what the matte color it. However, if you
use PNG32 or PNG8 with Alpha Transparency, it will remain smooth.
The only problem is the same problem with most things on the web:
Internet Explorer. Alpha Transparency doesn't work in Internet
Explorer 6 or below, without using some crazy hacks you'd have to
google for.

White lines on movie exported in DVD

ehi guys. I did just a nice movie with the suggestions of some members of this forum but at the end the quality of a 30minutes movie exported in DVD was not so much principally because of some white lines present in some pieces of the movie. These white lines are not clearly detectable, but still they disturb the vision. I guessed that this effect was due to the low ram of my laptop (512MB). is that correct?

It sounds like it *could* be an interlacing issue, especially as it appears on the TV, and not the computer. Chances are that the computer's progressive scan masks this issue, while the TV's internaced display shows it.
Now, are all of the source Clips on the same Timeline the same? Were they all Captured via PE from a miniDV camera, over a Firewire connection, or are the from mixed sources? Having this problem come in during the play of the DVD indicates that it might be some of the source files, but not all of them.
More detail on the Clips would help. In the Project Panel, you can get the properties of each of your source Clips. Listing those would be a good start.
Good luck,
Hunt
[Edit] Antonio,
If it is a Field Reversal interlacing issue, you might get some useful information from this current discussion.

Flat Panel Burn ?

Hi All
Being new to using a flat panel screen can I ask what maybe a really stupid question ?
Can an LCD screen suffer fron screen burn as a CRT does and can ?
Thanks

Yes it can happen. I've never had any issues on my iMac G4 20" panel nor my Powerbook 15.2" display however the cheap Dell displays of which I have six sat on my desk at work all have smudges and stains whenever we display bright colours and I can clear see one of my colleague's wallpapers when he left the display on for all of a 15 hour night shift. I don't know if this is due to a different technology panel or just how they are treated.
The solution to this staining is apparently to leave a white display on for at least as long as the coloured one (although this isn't working on the Dells). I can't lay my mouse on the Apple article that states this though right now.
Personally I have Energy Saver set to turn the display off to save on my npower bill and it also protects the screen.

Hooking up 17" LCD Flat Panel Apple Monitor to an older G4

I have an older G4 and bought a 17" LCD Flat Panel Apple Monitor Studio Display to use with it. However, the plug from the monitor doesn't fit into any of the G4 connections. Am I crazy? I thought these monitors were created for the G4s. I tried the USB port, but nothing happened. Am I gonna have to get an adapter?
Sorry to be so ignorant. Can anyone help?
Thank you in advance.

The Apple Studio Display 17 (LCD) \[Clear lucite with white] has an ADC connector. Displays with ADC connector require a computer that supplies the required 25 Volt power through the cable, or if you use a DVI to ADC converter (with its own AC power cord) you can use a display card with DVI connector.
Which older G4 or what speed in MHz?
The PCI graphics and AGP Graphics cannot supply the 25 Volts to power this display. Gigabit Ethernet and later have the Power supply and the fingers in the AGP slot to pass that power to an ADC-equipped card.
