Q: MacBook Pro screen blinks

there's another video on that same page where they are comparing 2 macs at the same time and they both do it as well, think they are the older models but the problem looks the same.

Please Apple ...

Hi,
I bought my MBP way back in October, got it in one of the local stores since Apple could not deliver my online customized MBP without defects.

I do not have the flicker that some suffers at brightness levels from 2-5. But my MBP does occasionally (randomly) "Blinks" (like a blink of an eye, total black-out for split second).

Rarely the entire screen blinks, other times (again, the frequency is random) top half of the screen would blink.

I do not know when did this problem start to occur, didn't pay attention to it until it does it from time to time repeatedly.

The problem I have only seem to occur when the 9400 graphic card is chosen.

Mine is brand new 15 inch 2.93 and mine actually blinks at you on my 30 inch display. Looks like a refresh rate issue . My guess this is more a graphics card issue which a new firmware could fix. No I am not bring it back . Mine has two SSD drives. 6gbs of ram in it and right now my only machine. But this does need to get fixed the shimmering effect I am not really seeing on a consistent basis. The blinking is random and just above the half up I get about a 20 wide strip going across the screen on the blink.

Hi Guy Mancuso,

So does this "blink" also happen on your MacBook Pro's Display other than the external 30" display you mentioned?

I'm holding on to my MacBook Pro, for now, also waiting for next firmware; OSX updates.

In addition, caught my attention there, may I ask how you fit 2 SSDs to a MacBook Pro? ^_^

Yes they both blink at the same time. Either a graphics card or the remote chance of the 6gb of Ram. I am leaning towards the graphics card my thoughts if it was Ram it may not even boot. It's pretty random also and PS or Safari it has happened . So not program related

HI Everyone,

So I spoke to an Apple MacBook Pro product specialist and engineer, and they both felt the issue is a hardware problem rather than software. They had me go in to my local Apple Store for a swap. I oringinally had a 9C84 screen and now have a 9C85 screen WITH absolutely no problems (no flickering) and NO light leakage, which is usually the case with the 9C85 screens. I prefer the 9C85 screens as, per my experience, are not as yellow and display truer color. The blacks are really black, unlike the gray tones on the 9C84.

It's a W89 (11th week of the year) model. I have been running on my replacement unit for a few days now. I will keep you posted on any updates. Glad to have been able to land me a good unit after over a dozen replacements, I kid you not. Keeping my fingers crossed....I wish you all the best.

Some spec's on my MacBook Pro, in case you are wondering:

it took 12 replacements to get 1 right? o my.

Tavio,

Now that is interesting. I am on 9C84 at the moment, and Apple are shipping me a replacement which (hopefully) will be made after week 11. It should arrive in the next couple of days, so as soon as it does, I'll confirm the screen model and keep you posted on the flutter. It would be great to have some closure on this.

Sorry forgot to answer on the two SSD install. I bought a unit fromhttp://www.maxupgrades.com/istore/index.cfm for the second drive. Works nice and these folks are really nice to deal with.

Ok - I just had an email from Apple Care giving the serial number of the replacement MBP. It's made in week 13, so let's hope it has the newer display and the flutter stops. I'll keep you posted.

i just change this morning for a new one made on week 13.
I 'm installing now.

I will tell you what's new ...

Good luck - what display do you have?

i do not know yet ...

I'M transfering from my clone

keep us posted hotplug.. really curious about these developments. i still havent heard from apple yet. they will mail today

can you belive this thread has been marked as "answered"..? nothing answered to me so far.. just a big mess
