MacBook Pro screen blinks

Read my post on pg35.
I put the original shipped s/w on and it flickers (Feb09 + 10.5 Leopard).
I had NO s/w on......and it flickers.

Pointless keep asking about s/w problems and fixes.....its hardware.

Does anyone have any issues when watching a DVD on the Apple DVD Player. I thought I was beginning to to see the flash start to be commonly white. This is a new observation.

Is there any way to replicate this issue?

I installed Leopard onto an external hard drive. I booted from it. I ran it for 5 hours without any issues with flickering. When Im on Snow leopard, I get the issue several times an hour. I'm really beginning to think that some of us are having software issues instead of hardware. Not everyone, mind you. But some of us. We all seem to have the same blinking result in any case. Perhaps the issue is there due to hardware, but Snow Leopard just brings the problem out so much more.

I will try to install ''Tiger''

Dont install Tiger, its before the machine came out and wont have the drivers.

Look ive posted this before, its hardware. How can I tell...

I had a blinking MacBook Pro 17" like you all, it also had a SSD Hard Drive in which I installed myself. It flickered on Leopard and Snow Leopard. I took it back and Apple gave me a new one (exact same spec).

Ive had the new one for 6+ months and no flickering at all. The OS is the same EXACT OS as I swapped the drives, I DID NOT do a fresh install.

So I kept the OS that under 1 machine saw flickering but was fine under the other new machine. Therefore you can count out software as the software works 100% in the new machine.

Take it back, call AppleCare, read previous posts but dont just sit there hoping for an update.

Hello,
I do agree with this point of view. I'm not able to re-install Leopard on my MBP these days, but I'm absolutely sure the blinking issue has begun since I made the upgrade to Snow Leopard (directly to 10.6.2), at the end of november (2009). Before that, I never experienced blinking (or flickering) issue. I think (I hope...) it's (at least for some of us) merely a software issue, related, I guess, to an incorrect refreshing rate, or something like that (something that could be fixed by a graphic drivers update, thanks to... 10.6.3 ?).

Regards.

If you go back a few posts you'll find two news articles from December, 2008. Only a couple months after the computer first sold, and many months before SL came out. I suppose it's possible SL exacerbates the problem, but it's not the cause by any means.

Yes, I see what you mean. And I did actually read the posts (and the news articles) you are talking about before writing mine. But :

1. Certainly, the problem may have occured under Leopard. It doesn't necessarily imply it's a hardware issue. It may have been a graphic driver issue that a 10.5.x update could have fixed (some posts on this thread suggest that kind of interpretation, which may be taken in account, although I absolutely don't know if it's the good one). And maybe the issue comes back today because of the graphic drivers and/or graphic card(s) firmware currently used in SL 10.6.2.

2. As far as I'm concerned by this issue (and certainly I won't talk for the other subscribers to this thread), all I can say is that I never experienced it when I was running Leopard (and, from december 2008 to december 2009, I used my MBP in a large variety of ways).

3. I hope this can soon be fixed by a software update... But it's possible I am unreasonably optimistic 😟

I'm tired of this screen flickering!!!!!!!!!!!
Apple... WHERE ARE YOU??????????????????????????

I'm really tired too!!!!!

Someone have any news?!?!?!

I've try to contact a lot of time Apple, but every time they say that i've to pay (i'm out of warranty from only 2 month).

Please Apple do the serious company like all of us hope

Who ever marked this thread as "Question Answered", could he/she point us exactly to the Answer?! I am simply SHOCKED by Apple lack of response to this 1 year old thread!

The blinking appeared on my late 08 MBP after a logic board replacement due to a NON-blinking-related issue (before that the machine was OK in every aspect).

I've just had my logic board and my screen replaced and the blinking is gone (2 hours up to now and no blinking at all). Let's hope it stays like this.

At this point i can only hope about a driver problem.
Someone have try to contact Nvidia?

I too have this intermittent flicker issue. It began after the required reboot following installation of the iTunes 9.0.3 update. It seems to occur most reliably when the computer is first turned on and it goes away after I log in. Could it be that it is just a coincidence that it happened right after the iTunes update and totally unrelated to that update.

I have a 15-inch unibody from late 2008. I will call AppleCare tomorrow. Very aggravating! I also have one of the new 27" i7 iMacs with the yellow tinge issue (that will require replacement of the display) AND the screen on my 3G iPhone has developed strange grey lines (the screen is trash now). I no longer have confidence in Apple products.
