MacBook Pro :: Monitor Flickers A Few Times Then Goes Blank
Mar 30, 2012
I purchased a Mac Book Pro a year ago.I have been connecting a monitor with HDMI cable but in the past month my monitor screen flickers off then on every few minutes.Eventually it will go blank completely and not come back on.I had thought it was my monitor so I purchased a new one and it still does it. I have connected to my fiends monitors and they do it. Each monitor will act a little different but the end result is the same.My apple warranty just ran out and I suspect its a hardware issue since I can replicate it. [code]

I bought a 22 inch monitor. its a pretty generic brand, but its very high resolution and works great on other computers. i got the vga adapter for my aluminum macbook (i posted in this section because its closer to the 13" mbp). i have an apple keyboard connected to it. i try to use it in clamshell mode and when i press a button on the keyboard to wake it up the screen just flickers as if its trying to adjust the resolution. strangely enough, it works perfect in mirror mode. anyone have an idea?

I have a MacBook Pro 13 for portability to my classes at the university and a Dell 2209WA as an external monitor. One of the few good IPS monitors I could find around for cheap.
The monitor works fine in mirror mode with the MacBook Pro, but as an external display only it does not work. It attempts to wake up and then you see power savings mode again and the screen goes black as if there was no connection. Not sure what exactly the problem here is. Drivers?
The monitor works great with a Mac Mini I have and it works great in mirror but not in external display mode(the lid of the MacBook Pro closed). Anybody know of this issue? The cable is good and the MacBook Pro is not that old(a few weeks).

Every time I wake up my Mac Pro, the monitor flashes 2-3 times before it is fully on. Quite annoying. Any idea what it might be? I have the latest Mac Pro 2.66 Quad (got a referub about a month ago) and LaCie 526 (same as NEC 2690). Basic video card, DVI connection.

I have a new LG W2343 monitor capable of displaying 1920 x 1080 connected to my White Macbook early 2009. I have the external set to mirror and have made the laptop display go to sleep by closing the lid and then waking all else up by using the external mouse.
So at the moment the laptop monitor is blank and the external monitor is displaying 1280 x 1024. When I now try to switch the external to 1920 the external screen goes blank too. I then have a blank laptop and blank external meaning I have to force shutdown by powering down.
Why can't I switch the external to 1920?
Any advice gratefully received as I am tearing out what little hair I have left.

I'll cover the background to when this started happening.
I took my macbook out of an outer case to clean the shell itself.
I used wet ones which have alcohol so I wasn't worried, but also wasn't careless.
I once got a screen that said I needed to restart my computer. So I did.

Whenever I move my macbook on my desk with the lid open, or when I open the lid, or when I close the lid, my screen flickers to black and then back open many times. Is this a weak connection some where? Sometimes the screen will stay black until I move the lid a little bit. I bought it refurbished from Apple this spring. I do not have applecare.

I have an Intel IMAC, which is now out of warranty as I have had it for 16 months (and I was dumb enough not to get AppleCare). A few days back, my computer would not startup and everytime I hit the power button, I would hear some spinning noise but no chime from the iMAC. Yesterday, I tried it again and this time I heard the chime but the monitor did not start. I was then able to SSH into the MAC and see that it is indeed connected to the network and booted up, but the screen is still dead. Any ideas what I should do before the painful trip to the apple store ?

I'm using the MiniDisplay port to HDMI on my MacBook Pro and connecting it to my 720P Dynex HDTV.
All my MacBook Pro does is flicker 3 times for about 8 seconds that it goes back to normal.

She has a 2008 Aluminum MacBook, the standard 2.0Ghz model. Occasionally when she moves the screen or tries to angle it, it flickers. This doesn't happen every time.
I honestly haven't tinkered with any Mac laptops once the unibodies came out, so I am hoping someone can shed some light, give some advice, and maybe throw out some ideas for repairs.

with the keyboard. I was so happy! That is, until I closed the lid to make it sleep.That's when something horrifying happens. The Apple logo flickers after a little noise from the SuperDrive. It's as if it doesn't really want to go to sleep, but the little light is glowing.I'm really concerned; I do not want to send this one in to Apple again. The process is too long to bare without my MacBook!

I just got a new MBP i7, and whenever the graphics switch from the Nvidia 330m chip to the Intel chip, the screen "flickers" black for a short moment before reappearing. Can anyone with a new MBP comment on this behavior? It doesn't happen on the switch from Intel->Nvidia, just the other way around.

Last night I was working in Adobe InDesign and Photoshop when my screen began to flicker like crazy and eventually froze. I could still move the cursor around but nothing would work. I couldn't force quit any of the applications or shut down the system. It eventually shut itself down and after restarting everything seemed normal. About 20 minutes later it did the same thing as I was switching between Safari windows using Expose'. (I recorded a small clip of the flickering and put it on youtube if that helps: [url]...?v=UBjRwRu4IOg ) After the second time this happened I again tried to start it up and it loaded to a gray screen, no startup chime, no apple logo. Nothing. I hit the power button and it shut down again. And the next time it booted all the way. I then shut it down with the intention of calling Apple Care today but apparently my Apple Care ran out in the last month or so. So, I'd have to pay $49 to talk to them about this issue. I thought I'd come here first.

After a few minutes of rebooting the machine i will use spotlight and it will be very flickery. Like when updating results, the blue bar flickers white and blue very quickly and almost unnoticeable. Also, related, when scrolling a list in the dock through a stack shown in list mode, it flickers a lot there as well. Is this normal behaviour for these machines/leopard in general? I'm used to using a crappy old iBook so i dont know if im just being pedantic.

I present to you today a baffling conundrum which has been vexing me for months. Around Christmas my sister got a huge raise and bonus, which resulted in a flurry of new technology rushing into the household. All at the same time we set up a new wireless router, (for our wireless modem) an Xbox 360 and SnowLeopard for my MacBook Pro.
I noticed that late at night, after the Xbox had been turned off, my internet connection started getting strange. without the system acknowledging anything had happened (all 5 bars in the airport symbol, my AIM client still claimed i was connected) i would suddenly be unable to load anything (in any browser) or send or receive any IMs.
I would turn my airport off and immediately on again, then the problem would be solved. then, exactly five minutes later, it would happen again. I've been able to connect this "funky-internet phenomenon" as I like to call it, to the Xbox being OFF. I am a walking detector for when the machine gets powered down. this only happens when Xbox is off, and the second it is turned back on, my internet stops doing this.

My screen just started to occasionally have a flicker of a white line show up...It doesn't happen that often, should i worry? Is it worth taking it into apple? (Under warranty still) Since its not consistent i wont necessarily be able to show them what its doing..
