Q: MacBook Pro screen blinks

My new MacBook Pro display screen is blinking or flickering every few minutes now. I've only noticed it when I've switched to the integrated 9400M graphics processor. I don't recall seeing any blinks when using the discrete 9600M GPU. Usually it is only the top half or so of the display that blinks or flickers for a split second. Anyone else having the same problem?

MacBook Pro (Late 2008), Mac OS X (10.5.5), tv, iPhone, iPod Touch, et al

    Don't give up, the same stories keep coming up about apple support "diagnosing" the problem and just sending you home because your screen doesn't have a problem according to them. Even screen and logic board replacements don't work according to forum users.

    Report this problem to Apple directly on their feedback form: www.apple.com/feedback

    I listed all suggested fixes and their outcome in a blog post, as well as the feedback somebody is giving me after filing a complaint against apple with the BBB. Apple should call him tomorrow (tuesday 25/01) about the issue.

    Follow up on the call here:

    Ref. jorrelemargis blog:
    I'm not totally agree with you. Replacement of the motherboard is the solution in many cases. I think it is a somewhat lack of interaction between the screen and motherboard. I have changed my screen, but the issue was just worse. Replacement of the motherboard was my solution. Have not seen the flickering since. A total of four repairs before it was resolved. Every time I called Apple support, it seemed as if they had not heard of this before. But after I filmed it, and referred to this forum they appeared quite different.
    This is my first Mac. I'm not sure my next will be one.

    Just adding my name to the great disgruntled. One graphics processor overheats and stops and the other flickers incessantly. This is my first Mac and I aint impressed.

    @WAndS_0044 those are exactly the same symptoms as I'm having. Some have reported that a logic board replacement has worked, while others say it didn't solve one bit.

    If it does, Apple should take care of those that have the issue at no or little cost. Keep posting the problem to http://www.apple.com/feedback so that at least maybe one day we get an official statement about the issue or possible solutions.

    A solution is all we ask for our investment.

    Thats EXACTLY what mine does! But sometimes its not even that little portion of the screen.... sometimes its the whole screen that will flicker black! Its so frustrating! I'm afraid to wake up one morning and find that my screen won't turn on at all. I need this laptop for school work, since I am a Graphic Design student, and my parents spent a lot of money on this laptop, and I spent a lot on the programs for school to put on it.

    When it was sent home with me, the guy that repaired it said he "could not replicate the problem". But all he did was play a video. When I'm on it on the other hand, I'm on the internet, Yahoo IM, Skype, and iTunes constantly. So it decides to flicker when I am using it, just not when they have it. It was so frustrating.

    WELL WELL WELL,

    i received a reply from apple. the engineering department stated.
    they know it's a problem, because i've been told that the resolution to this issue is to switch to the 'higher performance' setting of the nvidia 9400/9600.
    if you want to use your laptop without having to plug it in for power and at the 'better battery life' setting (that's what a laptop user would like to do, isn't it? use the laptop when there is no power source, right?), anyways, then you have to get the motherboard replaced.
    BUT, there are many on this thread that have had that done and still no resolution. and there are many that have switched the setting and have had the machine freeze.
    i guess if you're under warranty apple is willing to switch the motherboard out to their hearts content. UNTIL, you're not under warranty anymore.
    i had this problem while under warranty and they didn't replace the motherboard. the genius at the genius bar reset the pram and did some other key combination and it went away. i was so happy it had gone away. but the blinking came back and worse than before, but of course, now out of warranty.

    IF YOU HAVE THIS PROBLEM AND YOU ARE STILL UNDER WARRANTY, DEMAND TO HAVE THE MOTHERBOARD REPLACED. THE APPLE ENGINEERING DEPARTMENT SUGGEST TO DO THIS.

    here's the company's response you'll find on the bbb website.

    'Company's Initial Response - Posted 01/24/2011
    Thank you for your recent correspondence to the executive offices of Apple regarding the above referenced customer. The following excerpt from the Apple One-Year Limited Warranty is available at http://images.apple.com/legal/warranty/docs/cpuwarranty.pdf: “WARRANTY. Apple’s warranty obligations for this hardware product are limited to the terms set forth herein. Apple, as defined in the table below, warrants this Apple-branded hardware product against defects in materials and workmanship under normal use for a period of ONE (1) YEAR from the date of retail purchase by the original end-user purchaser (“Warranty Period”). If a hardware defect arises and a valid claim is received within the Warranty Period, at its option and to the extent permitted by law, Apple will either (1) repair the hardware defect at no charge, using new or refurbished parts that are equivalent to new in performance and reliability, (2) exchange the product with a product that is new or refurbished that is equivalent to new in performance and reliability and is at least functionally equivalent to the original product, or (3) refund the purchase price of the product.” Apple records confirm Mr. Lanz’s MacBook Pro was purchased, on June 11, 2009, and that it was covered by the Apple One-Year Limited Warranty. Since submitting his letter to the Better Business Bureau, this office contacted Mr. Lanz regarding the flickering screen on his MacBook Pro and explained it was an issue that can be resolved through repair service. While Apple declines Mr. Lanz’s request for in-warranty service, based on the terms and conditions of the Apple One-Year Limited Warranty, should he need assistance with determining if his computer is eligible for out-of-warranty service, Apple encourages him to contact AppleCare at 1-800-275-2273, or schedule an appointment at his local Apple Retail Store or Apple Authorized Service Provider. Apple appreciates the support of our customers, including Mr. Lanz’s, and strives to reach mutually satisfactory resolutions to all customer requests; we apologize that we were not able to do so in this instance. Sincerely, Nate Doss Corporate Executive Relations Apple

    I'd argue that a £1700/$2600 computer should remain fit for purpose for longer than the stated 12 months of the warranty, and I'm sure that I'd be backed up by UK Consumer law.

    Each repair would be covered by another warranty though so you'd be looking at replacement motherboards for life

    yup, the 'engineering department' has stated to me through the 'Corporate Executive Relations Apple' representative, that the replacement of the motherboard will fix the problem.

    therefore, take your late 2008 model macbook pro's to apple and tell them you want the motherboard replaced.

    and while you're at it send your feedback about your problem to apple directly:

    I've been thinking about it, and while there is no legal obligation that Apple has to repair out of warranty macbook pros, if they have acknowledged the defect, I would like to see an option to extend my AppleCare Coverage even though I am past the standard extension limit.

    I would pay cost for the AppleCare upgrade.

    What really upsets me is that this is a known issue (for how long, we don't know) and we have no option now to even get discounted support for an (unofficially) acknowledged defect.

    The product was produced with a defect, so Apple remains obligated to provide a solution. Getting NVIDIA or Apple to admit that the 9400 GPU has a manufacturing flaw which is in both old and replacement motherboards is the problem. NIVIDA is not going to fix the flaw and remanufacture new product for old logic boards.

    The only long-term solution is replacement with a newer model which does not use the NIVIDA 9400. This would best be accomplished with a substantial discount on a current MacBook Pro.

    I agree with the above post, i would be willing to pay for an upgraded model without these issues at a discounted rate.
