PowerBook G4 users discuss \"white lines\" issue

PowerBook \"white lines\"

Several Power Book G4 owners on Apple's online support forum discuss an issue where appear on the display after extensive and prolonged use. The issue seems to affect a wide range of Power Book G4 (Titanium generation) models. However, a large number of users with the 667Mhz model report the issue. Most users are running Mac OS X 10.3.8, and the issue does not appear to be software related, as it occurs on system versions, and does not appear on a screen capture. Apple has yet to respond to the issue publicly.

    Also happens on iMac G5s

    Seems to be a general issue with LCDs. Some LCDs seem to have uneven backlighting. What causes it is unknown. Whether Apple will replace the LCDs with this defect is subject to whims of the moon. This is much like the dead pixel problems people experience. Take it up with AppleCare if this happens so that the problem at least gets logged.

    My wife has this issue

    She has an original 500 MHz. model which developed a line in October. Her's is green, not white because she lost control of the blue and red transistors in the stripe.

    Basically, this is a repetitive strain injury for the LCD. Her machine has seen a lot of use and it is out of warranty now. A replacement LCD is conveniently almost as much as a 14" iBook.

    If this was a condition in new machines, this would be a big deal. As I see it, it's just a bunch of whiners trying to get replacements for normal wear and tear.

    Warranty

    I was experiencing the white line distortions whenever I used my 550 Ti powerbook for an extended amount of time. However, I took my book back while still under warranty and Apple replaced the internal video cables with better shielded cables (or added a heat shield of some sort), no charge, and they were full aware of the problem too. I have since purchased the 1.67 15" and do not have that issue with this new machine, in fact, the new machine runs much, much cooler.

    Chalk another up...

    Ya know, I'm pretty I'm pretty disappointed with the quality control that went into my 667 Ti, let us list the headaches:
    1. A fan always on that gives my girlfriend's hair-dryer a run for the money
    2. Defective paint! I mean really, what other laptops do you know of that have had defective paint?
    3. A cracked case over my CD drive that apple has graciously fixed twice until I was out of warranty.
    4. And now I am worried about getting white-lines (no I haven't had them yet, but the display has been doing some glitchy things the past couple months....)
    All in all, I love Apple, I've probably made 30 of my friend's live better forever by convincing them to get a mac, and I made the big Switch with this powerbook.... but it SUCKS to have the powerbook with so many freakin issues!!!!!! (sorry for venting)

    Mine's fine...

    My TiBook 667/DVI is still happy with the 10.3.8 update. I'm crossing my fingers now, though. Thankfully I have AppleCare until February 2006.

    Mine's fine too

    I have a Titanum 400 MHz, works just fine, no problems with
    10.3.2 - 10.3.8. CD-drive was once replaced under warrenty, but
    that's all. As some said, it's probably mostly wear and tear.
    I'd bet similar stuff happends with any computer, not just Apple.

    Inverter display cable?

    Does anybody know if this is caused by the video inverter display cable? I have looked around for others that have had this issue and fixed it themselves. Such as replacing the inverter display cable. This issue has happened to my Ti book(500 mhz) after my cat knocked it off my desk. Several white and red lines on the right and lately one blue 1px in the center. I had display cable problems in my old Wallstreet 13.3' pbook in which Apple replaced the first time, the second time when the issue arose 6 months later they wanted to charge me for a new 14' LCD. I bought a display cable for the 14' screen and fit it in the LCD case, and it has worked ever since, with no display problems. So I am looking for anybody who has either fixed this themselves or know exactly what is cusing this issue.
    Thanks
