I have five 1 pixel lines on my display for a about two weeks. It started as 1 blue line now its 5 lines, 3 blue, yellow and pink.
Tried switching off, changing resolutions and colours, nothing worked.
Warranty ran out the week before this happened. Is there any way that I can fix this without sending the imac in to a dealer/shop? I am kind of far away from any authorised dealers.
I know this reads funny but I think my lines are going away. All on their own. The thick white line which was there while the others developed and flickered is now kind of wavy. Hahahaha! These machines are really taking on a life of their own. Who knew digital electronics would turn out so temperamental. Anyone saw the movie iRobot, or read the Book?
Well, I guess this is a tricky issue. Since my lines appear differently and always in the same way, one at boot and the other just when the apple shows (display initializes to show graphics), I'm thinking it may not just be hardware. The video BIOS might also be involved. But my gut still says it's a connector issue. Come loose cuz of the heat.
That's my penny's worth for today. Hope you all are doing fine other than the line(s),

Y esto es un desastre de lineas en ventanas con bloqueos incluidos.
Creo que con tiger no pasa.
por cierto powerbook G4 con leopard sin problemas,
Salud y Felices fiestas!!
I've had sporadic lines on my iBook since day1. It's nothing to worry about as they come and go. I'm sure these imac screens are much the same. Give it a week or two and the screen will be as good as new.

UH? What the heck are you talking about? this is a real problem that will NOT get any better once it appears. You certainly are a positive wishful thinker but a naive one.
Well like I say, I've had lines for 3 years and my screen still works. Have you tried calibrating? I've got an eyeonedisplay2. It's really good and was well worth the over-inflated price I paid at the mac store{£200}. If it saves my monitor then it's been money well spent.
Have you considered an apple cinema display? I hear they are rather good.
Since my post i have had my computer repaired and it is working fine now. I have also been reading the absurd posts being thrown at this thread like its open season on Apple. I have yet to see anyone going out and getting to the bottom of this. If you have a non apple store, certified repair center near by I suggest you take your bad monitor in and have them inspect it. Even if you're out of warranty, an inspection to find out the actual cause should not cost more than 20 dollars or so.
Your problem may be unrelated to the one that started this thread, but you can't know until you get up and do something other than post all day on a forum. I also haven't seen anyone posting evidence to support their claims of bad monitors, and not bad software, environment, or other sources. Before calling apple about my problem i did extensive testing to eliminate anything outside of hardware failure.
And finally, I have to say I am appauled at the mud being thrown in Apple's face. Yes this is an unfortunate problem, but getting verbally violent and disrespectful does not make you look any better. Foreign policies do not normally apply to imported goods unless the manufacturer has signed legal documentation agreeing to it. I know this because i've dealt with foreign legal documentation more than once.
I leave you with these simple suggestions.
1. Don't lower the overall appearance of this movement by being slanderous, threatening, and all around useless.
2. Post extensive details about the problem. Don't waste time and space with little "third line today" posts.
3. Check, and be ready to prove, that this problem is what you say it is and not something else. Test in different locations (other than just your house), check firmware, use a repair center for investigation, and if possible get serial numbers of LCD cores, not just the computers.
Logar,
some good thoughts on your problem troubleshooting suggestions and suggested posting guidelines. I agree that the more hardware and software details people include, the better we can all understand what is going on. Clarification is good.
Will you please share with us what the corrective repair action was, in your case? (for your 24" Aluminum iMac 'Mid 2007' model)
Granted that not all cases may need the same corrective action as your, but still, it would be useful for folks here with similar issue to know what sort of physical repairs they might be looking forward to.
I have been following this problem very close also, and besides the iMacs, there is a very old batch ( as far as 2005) of literally hundreds of PowerBooks 17" with
exactly the same problem. The threads and posts on this PB problem, that were posted here, were ALL of them, deleted (who knows why, it is a mystery), so, let me tell you that this is definitely a hardware problem. That is the bottom of this. In fact, several users that have taken their iMacs and PB to the Apple service for repair and after getting their machines "repaired", the problem has surfaced shortly after, as short as one month later, so, the very bottom of this problem, is unknown even to the technicians who only change a couple of items: motherboard and/or LCD.
The problem of most of the people here, is exactly the same as OP and if people rant and throw mud at Apple is because they(we) are expecting much more from a company that has always had a very good reputation as being friendly and caring towards their customers: Apple think different and Apple uses jeans instead of suits and Apple has the record for the best and most reliable hardware for years, and Apple has a truly loyal base of fan-boys that are always praising Apple´s virtues, so,what do you expect when Apple, deletes threads, and do not recognize the paternity of a defective hardware, a bad design and a faulty quality control?
BTW there are over 250 (mostly iMac)users with this problem that have signed the petition to apple for an extension of warranty. Do you really think they have not tried hard to get to the bottom of this problem?
Most of them and also most people on this forum and the PowerBook people too, have tried to reach Apple unsuccessfully. What you are suggesting are peanuts compared to what some people have tried to do to make Apple listen and acknowledge this problem since 2005.
Please, try not to patronize the people on this forum because the last thing we need is someone to tell us that we are some kind of retards that are no doing things right.
I only hope the mods here do not delete this one 😉
My problems started with unusual lines appearing on the screen after my computer had been up and running for at least 4 hours. I would get random vertical stripes and a sort of horizontal shuffling. Left third of my screen would suddenly be the right third and everything in between would just go wherever it pleased. At first i thought software was the issue so i booted in several different modes to verify that the problem would occur with or without the software of the computer involved.
Over the phone Apple's best solution was to reset the motherboard of the computer by discharging all static from the machine and keeping it unplugged for a little while. It worked only because the problem would tend to go away when the computer was shut down for an hour or two.
My tech guy at a local repair center narrowed it down to the boot rom, logic board, or the monitor core itself. In the end we found that the LCD core of the screen was bad. What exactly was wrong with it we will never know, but the top possibilities were some form of contaminant in the housing of the chips, a tin whisker, or some narrowly short circuiting solder on the board.
My problem went miles beyond a couple small lines on the screen, but I would say that these other display issues are really just a mild form of what i got stuck with. A new "monitor" was the fix I needed, and i've been using this new one since the repair without so much as color shift.
I forgot to mention that my parents own a white iMac purchased literally days before the newest models came out. Serial number W8732xxxxxx. No problems have occurred yet, but i've got the APP on that unit as well as mine, and my MBP. Definitely a good investment for any apple product.
I appreciate your post and understand your point of view. The thing is posting on this forum is the last desperate action I've taken about my 17 Imac Intel Core duo 2006 problem. Trust me, i whish i didn't have any reason to post here. As for as I am concerned this problem is not unique but affects several people. I have several computers at home and only the imac broke down. Dell had similar problems with some of their screens and did something about it:
After the resignation the only thing i can do is let everybody know. i guess you are right I'm maybe I'm to emotional but hey man... that's the way I am...and I should be enjoying my mac, not checking hardware, software, consulting layers or buyin a new screen to be placed in fornt of the stylish imac.
As per my short posts, please note every new line i get on my screen I'll post it here. Is the only thing i can do when no one out there hears me out, and is also a way of letting apple know how the problem evolves. If you want proves i'll upload some videos on youtube so you can see them.
As per the law, in case you can read spanish, check the following link explaining what Apple and its retail stores should do about it.
My iMac 17" had the same problem most members described in this topic - vertical single pixel wide lines appearing just after the 1-year warranty got over.
Upto about 3 days back, my mac had about 17-20 lines, but now my 17" widescreen display is reduced to a 13" square. One third of the display from the right now has two vertical lines of black and white, several pixel blocks wide, that cover about a third of the display and is not addressed by the system to display anything.
This is now getting so frustrating - ealier I could use my mac in spite of the lines, but now all my app windows get cut off from about the third of the display. It remains that way even in Vista on bootcamp.
I think all affected mac owners must get together and confront Mr Jobs and team at public events like the upcoming MacWorld 2008 and ask them to own up selling us a shoddy piece of work and pay up. I don't want a replacement... I'm tired of staring at the piece of junk on my table.
