Q: Strange vertical stripes

Argh, I wish I'd taken a picture of the problem--it hasn't happened since Friday, but every so often, when I wake the MBP (Penryn) from sleep, I see alternating bands of light and dark vertical "stripes" along the screen. It looks as if half the LED backlights did not activate.

However, if I shut the lid and then re-open, it goes away. What gives? Is this a hardware or software fault?

If it happens again, I'll be sure to take a photo. This is ridiculous.

15" MBP (Penryn), Mac OS X (10.5.2)

    is the issue only with the 15"? there are no postings i can find referring to the 17".
    or, is it that i missed those postings?!


    IMHO the current standard 17" MBP doesn't have a LED backlit display, unless you buy it with a BTO high res display.
    So either there are under 17" MBPs with highres display out there to generate a report in this thread or it is not plagued by the stripes issue indeed. The one with the standard screen can't show the issue due to the lack of the backlit LEDs.

    Count me in as well.

    My MacBook Pro was purchased (BTO) in march, and I've had this issue appear 4 times now in as many months. Most recently it happened tonight. The headphone jack is also dead now.

    10.5.3 does not fix the issue and, in fact, I am getting the stripes much more often now.

    I have just got back my MBP.

    After watching the pictures of the stripes and / or the yellowish b/w gradient they replaced the screen.

    Now its code is 9c83, which I have read to be Samsung. Samsung are considered to be better than the AUO, but IMMO they are similar if not even worse. This screen presents a strong light in the bottom part and, in particular, in the lower left corner.

    I could not replicate the stripes by shooting 21 pictures with photo booth at max - 6 illumination. I will let you know if they show up in the next weeks.

    Do those of you with a Samsung display see some strong lights in the bottom / lower left corner?

    PS. The price of the only display is 580 + 20%vat euro. A recall campaign would be quite expensive if the problem is the display.

    i spoke with apple tech support "level 2" (haha) today on the phone about this. i am not a current mbp owner, but am looking to purchase one in the next week or two. i was told that this issue is documented on their end and is in the process of being fixed. they also assured me that all computers being shipped out currently do not have this problem and that anyone experiencing this problem can call apple (with their serial number) and request a replacement regardless of how long you've had your mbp (with or without apple warranty), and if the issue ends up being hardware specific for all models being affected, then they will soon institute an exchange & repair program for this issue affecting this model of the mbp.

    also in the call, i also noted a security vulnerability in all macs affecting the security pane setting "require password to wake computer from sleep or screensaver". when this setting is checked and the computer's screensaver is active, you can press any power-specific keyboard shortcut (turn off screen, sleep, restart, shut down, and possibly any system-wide shortcut--i haven't checked) then cancel the password input dialog, and the shortcut will be processed anyway, without authentication. they said my call was the first one about it and that it would be sent immediately to the software engineers. please reply with your system specs and os x version if you can confirm this vulnerability and if this should be reposted elsewhere, then let me know.

    I went 7 weeks and never saw the stripes... then it appeared at the weekend (shift, cntl, eject)... but then yesterday, and today ! I too loaded 10.5.3 and if judge before & after it has got worse. Blimey, Apple really don't have a clue how to fix this and/or they cannot be bothered. Once in 7 weeks I can easily live with, a daily event well that's another story. Mind you, options to redress are limited...

    Just an FYI really, but I just spoke to a Genius at the local Apple Store and showed him a photo of the backlight stripes.
    He says that Apple is indeed aware of the problem and it is not uncommon. As of this time there is no timeline for a fix but he suspects that it will be a firmware fix and that there is no way that taking the machine into the store will fix it.
    All that you can do at this time is use the keyboard shortcut to reset the screen.

    Here's hoping for 10.5.4?

    I have just realized something that I think was obvious for all of you.

    The manufacturer/model codes in the color profile are simply text strings written in the ICC profile.

    In my case the screen has been changed by the repair centre. If I download and use ICC profiles available on the net, those codes change. So I can have a Samsung, AUO, Chimei, or LG monitor depending on who created the profile. If I use the first profile, that is a system profile, I can read the 9c83 string, but how can I be sure about my screen model?

    If I boot into windows xp and use the astra utility, I am not able to read anything because the trial version of astra I am using is not able to detect any monitor.

    Thanks.

    Good point there Mac Cardi. If I am correct, about 100 posts ago there was a MBP user who claimed to never see the stripes while booted in windows. The profiles for the displays are specific to their model, but I would also like to know that question myself. I wish I knew the answer:

    "How can I be sure about my screen model?"

    Thanks.

    If you have an external disk, you can try to install Leopard on it. Normally the installer will choose the profile corresponding to your lcd screen.

    It's a bit long, but I don't know any faster method.

    Looking for a simpler method, I have found the utility:
    SwitchResX

    This utility says that the code is 9c83 even if I am currently using a profile with 9c67 as screen id.

    Do you think this utility is able to read the code directly from the screen or is it just reading the code in the computer/system/default profile?

    Add me to the list, I just got the dreaded stripes when I was using skype and writing emails... The computer was on battery with 40 % power...

    Whether it is a software power management of the display or a real hardware problem, this needs to be addressed and solved asap.

    What they told you is not true.

    I called AppleCare after reading your message to see if I could get this problem resolved, and they have not been informed or made aware of this issue. It is being treated as any other random problem, no differently than the first few posts in this thread. The AppleCare rep told me she had never heard of this issue, so I mentioned the ADC bug number and she told me she didn't have access to the ADC database. This thread also meant nothing to her. We went through the PRAM reset, SMC reset, etc. At the end, she offered to open a repair ticket and have me send in the laptop, but warned that without being able to reproduce the issue, it would be difficult to fix (in other words, I'd get the refurbished scratch-n-dent replacement that people have been reporting.)

    The closest Apple store is almost 50 miles away, but I might try to drive up there over the weekend and see what they have to say, but I don't expect much. Since the end result of the repairs tends to be a scratched-and-dented replacement, I will hold off until we start seeing positive confirmation of diagnosis and resolution from a repair. I take extremely good care of my machines, so the idea of getting a damaged refurb is not appealing.

    Since I have had the machine (and it's BTO) almost 3 months, I am not eligible for replacement service, so I am holding off on the ineffective repair/replace with damaged refurb until I have to.

    Found this while searching for answers:

    {quote:title=:}
    It seems that the MacBook Pro isn't the only one suffering from this issue, because one of the commenters on the Crunchgear post says that he "had this happen on a new Dell XPS M1330 right out of the box. The technician that came out said that it was pressure points on the screen during manufacturing and certain screens were damaged."
