I originally posted this in the wrong category for the MacBook Pro instead of the Monitor catagory. I am wondering if anyone else has the same problem. I posted the following last night.

*Still an unknown issue with Apple Tech Support*? After 2 calls to product specialists and apparently an undocumented issue by any customers contacting tech support this seems to be a widespread worldwide issue. In one form or another with no answer after several months of the computer release displays are blinking, flickering and flashing to name a few descriptions of this problem. Mine flashes solid black for a fraction of a second and comes right back on. I have had this issue in the power saving mode as well as the better performance mode so that kills that theory. To this point there has been no pattern that I have been able to detect. I can go for weeks without a blink and all of a sudden get 2 in 5 minutes. Usually I am pretty good at troubleshooting but this problem has no pattern and is so intermittent I think it's going to be a tough one and I truly believe Apple has no clue as of yet so they are not addressing it publicly or to individuals calling in with the problem. I purchased my computer November 29th. I used it for over a month without ever seeing the issue. When the new monitor came out I still did not experience any issues with either display in the area of blinking, flickering or flashing. There is a video on Youtube that I have located showing the exact same issue as mine. Though the person on Youtube has a non-apple display and mine is the new 24" Apple display and it is the exact same issue this rules out the problem being the external display. Well, I can check that off as well. This is the link. http://www.youtube.com/watch?v=u-dQIgfIFsI Does anyone else have the exact same issue as mine? I am thinking maybe it is something in the 10.5.6 update. Who Knows?

*BTW this problem is not at all heat related.* It can happen during heavy use or very light use at low temps. I have purchased many newly released Apple Computers over the years and have actually had great luck with them. I hope this is not my first lemon.

    I bought a MacBook and the 24" Cinema Display a week ago and am having similar problems. The display will go black without warning--and stay that way. Sometimes the Book goes dark, too; other times it stays on. When the Book also goes dark, I hit the power button, which usually brings up both screens. When the Book stays on and I go into System Pref., choose Displays and click and unclick "mirror displays." I've tried using the Book in both clamshell and open modes and had the problem (external display going dark) both ways.
    Tech support people didn't seem to know how to permanently solve the problem, but during my last call I was told that Apple is aware of problems like these with the new display. The rep said they would be providing a software patch to fix it soon but couldn't tell me when.
    Has anyone else heard this? I'm trying to decide if I should return the display before my 14 days are up. Any advice?

    Brand new cinema display straight out of the box. Goes black four or five times a minute. And someone here says 'Don't worry'? Can you imagine the fuss is this was Dell?

    I seem to have solved this by switching to Graphics Higher Performance in Energy Saver on my Macbook Pro. This switches in the higher performing Nvidia card not the slower one for battery only use. No flashing since.

    Mine is a brand new 2.66 so it clearly isn't restricted to 2.53s. Have had one flash since switching to better performance. Will see. Clearly the problem is with the MacBook, not the screen, which is lovely (as is the MB when everything works).
    Well done on what you said to Apple though - more of us should do this.

    I am also having the same problem with my 20" screen. It will flash on off a few seconds then its fine for awhile then starts doing it again. I took it in to Apple store which they shipped to apple and they found nothing wrong. Whoever looked at it didn't look hard or long enough. Started doing this several months ago and warranty just ran out in February. Any ideas other than what I am reading on here?

    Seeing this problem on Unibody MBP 15" with the new 24" display connected via displayport. For me, it seems to be triggered by iChat videoconferencing, though sometimes iChat VC works fine without flashing.

    Just came across this thread. I have the previous generation 15" mbp...same issue - screen goes black for a moment, and I hear a processing type sound. It seems to only happen for me when I am using ichat - both when I have done video conferencing, as well as when I am simply chatting. When the screen goes blank, it knocks me offline...then it could happen a few times again. Randomly happens however, as I've gone a week or so even without it happening - while using ichat.
    I have a co-worker who got the same model as me, and has the same exact problem. I've been reluctant to bring it to apple because of these types of threads, and the fact that the few people I know who have had this issue, all have had no luck with apple either - so why waste my time until they actually have a solution?

    I really would like apple to at least ADDRESS this issue so we can know it is being worked on. Very frustrating - especially when I have to explain to my client's why I can't seem to keep a connection during production meetings! It's become a disclaimer at the beginning of them lately!

    I have it too. This seems to be software independent.
    I'm currently (trying) to watch a video via VLC player on the external 24" Cinema plugged into my MacBook Pro 2.53. The screen blacks out for about 1/2 a second very randomly but in the last 15 minutes it has done it 12 times. I'm running in low power graphics mode with the sound coming out of the cinema display.

    The monitor is brand new - I bought it 2 hours ago! Everything else seems to work fine, and the only thing that causes the blackout would seem to be playing video on it although I haven't tried every application. Photo editing is fine (which was the reason I bought it).

    Its really annoying but the date span of this thread would seem to suggest that Apple haven't a clue. Oh dear.

    Just want to confirm, I also am running in low power graphics mode when this happens.
