Screen flickered and went dark, fans spin, display port works

15" Macbook Pro, I believe late 2009?
Booted it up for the first time in a week, the screen flickered a few times, and when it got to the login screen it flickered and went black for good. By black, I mean the backlight is on (Apple logo is lit up), there is just no image. The fan spins up and down randomly, and I can plug in an monitor to the display port and get the generic login background, but no windows. I tried logging in blindly with no luck. I reset the NVRAM, no luck. Tried booting under AC power, no luck. Any ideas? Thanks in advance.

I have a late 2009 imac i am having issues with my screen flickering and getting dark

i have a late 2009 imac 21 inch i am having problems with my screen flickering ND GETTING DARK DOES THIS MEAN THAT MY COMPUTER IA FAILING

I have partly the same problem (Sceen blackening) sparodically.
2010 iMAC with I7 CPU and ATI Radeon HD 4850 512 MB Graphics.
If I lower the brightness to around (3 or sometimes 4 of the on screen squares F2) the issue does not happen at all. I prefer a bright screen.
The issue commenced immediately after instaalling OS X 10.8.2 update one year ago.
The current software is OS X 10.9 (13A603)
The graphics on this computer are always first rate when working properly even at maximum brightness
There are particular days and times when the problem routinely occurs.
Some of my neighbors with iMacs have similar problems.
I live adjacent to the City of London in an area where new building seems to be developing faster than the various utilities and there are known Power Network issues. Professional surge supressors make no difference.
I live in a large property with four independent ring mais. The issue is present on all four rings. I have yet to take the computer elsewhere to possibly eliminate power issues from the problem.
I am reluctant to replace an otherwise fine top of range iMac which otherwise serves me well since the same problems might be present.

Screen flickering then goes dark.. :(

When I open my laptop, the screen flickers for less than a second and then goes dark. If I open and close it quite a few times, occasionally the screen will work, for hours at a time. If you shine a flashlight on it, you can see the dim desktop, so I know the computer is running. It is a mid 2010 macbook pro.
I have tried rebooting and resetting the laptop.., but the problem is persistent and its been weeks since i am facing it..
Have already had my logicboard replaced few months back... and now this....
Please help me.... as it is no longer under APP , i am worried how much its gonna be charged..
For a fault that i have read is very common with many people who bought their laptop during this year....
Any suggestion or ay kind of help will be great..

Make a Genius appointment. Troubleshooting and analysis are a free service at the Genius Bar. If don't have Apple Care and you need repair, then you would have to pay.
http://www.apple.com/retail/geniusbar/
Before you do costly repairs on an old Mac compare it to the cost of a new MacBook Air. Apple recently dropped the prices on the MacBook Airs by $100. Best Buy has been offering additional discounts on the Air. Prices start around $850.

If you do purchase a new computer, get 8GB RAM. RAM is soldered in and you can't upgrade later.

Just wondering what Apple's stand is on the issue with a flickering and a dark area appearing on imac 27"screen - forums seem to indicate this is not uncommon - and happens through normal use - so should be subject to repair (Sale of Goods Act - 6 years)

We are just users like yourself. If Apple has stated publicly about the problems you mentioned, it will be listed on their website and/or in one of their Knowledge Base Articles.
I have a 27" & do not suffer from such a problem. You should keep in mind that these are technical support forums. Generally, the only people posting here are those with problems. The thousands/millions without problems don't ever come here.
Think of these forums as a hospital emergency room.

Just upgraded to OSX mavericks on macbook pro mid 2011 version. Having a big issue here that whenever my mac comes back from sleep, i.e after I open the lid, the screen flickers and there is an error of Finder not opening properly. Any fix to this?

My daughter has had her Razr for about 9 months now. About two weeks ago she picked up her phone in the morning on her way to school when she noticed two cracks, both starting at the camera lens. One goes completely to the bottom and the other goes sharply to the side. She has never dropped it and me and my husband went over it with a fine tooth comb. We looked under a magnifying glass and could no find any reason for the glass to crack. Not one ding, scratch or bang. Our daughter really takes good care of her stuff, but we still wanted to make sure before we sent it in for repairs. Well we did and we got a reply from Motorola with a picture of the cracks saying this was customer abuse and that it is not covered under warranty. Even though they did not find any physical damage to back it up. Well I e-mailed them back and told them I did a little research and found pages of people having the same problems. Well I did not hear from them until I received a notice from Fed Ex that they were sending the phone back. NOT FIXED!!! I went to look up why and guess what there is no case open any more for the phone. It has been wiped clean. I put in the RMA # it comes back not found, I put in the ID #, the SN# and all comes back not found. Yet a day earlier all the info was there. I know there is a lot more people like me and all of you, but they just don't want to be bothered so they pay to have it fix, just to have it do it again. Unless they have found the problem and only fixing it on a customer pay only set up. I am furious and will not be recommending this phone to anyone. And to think I was considering this phone for my next up grade! NOT!!!!

External Disply flickers and went Black for a short duration after yosemite update 10.10.2

hi,
i got a mac book pro late 2008 and since todays update my external monitor flickers and went black for a short duration.
It seems that it happens, when i start a new app or i move a window across the displays.
Disabling the automated scaling of the resolution reduced the flickering but it still happens.
Does anyone faces the same problems and have an idea how to fix it?
I would appreciate it.
Sincerely
Lukas

Hello lukasfromholzwickede,
Thanks for participating in the Apple Support Communities.
It sounds like you've noticed flickering on your external display after updating OS X Yosemite.
I'd recommend starting with these resets to troubleshoot the situation:
You can reset the Mac's parameter RAM and SMC.
You can find these steps in this article:
Apple computers: Troubleshooting issues with video on internal or external displays - Apple Support
If the behavior continues, try going through the steps in the "Update your software and firmware" and "No video or no signal, image distortion, 'snow,' or flickering" sections of this article, as well.
All the best,
Jeremy

My screen flickered and now all I get is black and white pixels - any ideas for a fix before I take to the Genius Bar?

MacBookPro is about 8 years old now so has had a good innings. Last night the screen flickered, and then went off. Turning Mac back on again brought black and white pixels - small rectangles all over the screen. In background is little apple in middle of screen with the round rainbow timer thing vaguely visible. This then sticks and I just have the pixels nothing else.
Any ideas?
I have booked with Genius bar tomorrow but am feeling bereft!
Thanks in advance.

It's certainly a hardware problem that only Apple techs would be able to properly diagnose. Keep your appointment...

Mac air screen flickers and shuts down after startup

I recently loaded Lion on my 2011 mac air. After a week the computer started to have slow startup's, now when i turn on the computer the screen flickers and immediatly shuts down. How can i fix this problem.

correction the Mac Air is a 2010

Why the screen flickers and moves from one app to another by itself without being touch?

Have you tried a reset to see if that fixes it ? Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

Why is my iPhone 6 Plus home screen flickering and freezing up?

Try these steps as needed:
1. Reset phone - press both home and lock buttons for at least 10 seconds, releasing when the Apple logo appears
2. Restore to factory settings:
Use iTunes to restore your iOS device to factory settings
3. Get warranty service from Apple in the country where the phone was purchased

Screen flickers and goes black on boot up.

Have an older white MacBook that when I boot up, screen flickers and goes black, MacBook does power on.
Any suggestions?

I am seing a similar issue with a 13" White MacBook.
Powers on ... chimes ... then screen goes blank as if the machine has gone to sleep. Hitting the Return key or the power button wakes it again, but only for two seconds ... and repeat!
Any help gratefully received!

I have a Samsung HD TV and I purchased a Mini Display port to HDMI Adapter today. For some strange reason I get no display on my HD tv. I even tried switching a few HDMI cables and nothing popped up. I made sure my computer was updated. Help pls

I have a Samsung HD TV and I purchased a Mini Display port to HDMI Adapter today. For some strange reason I get no display on my HD tv. I even tried switching a few HDMI cables and nothing popped up. I made sure my computer performed all software updates, and I even tried calling Apple Support. They just told me to keep trying different hdmi cables and see if anything pops up. Does anybody know what the problem is? My HDMI cable is from "rocketfish" also my display port is too.

You may have the screen refresh rate set higher than the TV is generally able to track reliably. It may be able to get there most times, but occasionally loses sync because it is out of its nominal range.
I suggest you sit down with the manual for the TV and find out what resolutions at what refresh rates it intends to support through VGA, and make sure your screen settings are near (or below) those limits.

My Macbook (2009 White) Has had water spilled onto it, it all works apart from the screen. When connected to an external display it works fine, just not on the Macbook itself. Does anyone know how to fix this?

Take it to Apple and ask them to fix the physical damage the water caused.

I have a mid 2009 Macbook Pro and i know the Mini-display port does not support audio out but does it support HDMI out? or do i have to buy a Mini-display to DVI and then a DVI to HDMI adapters?

Run MDP to HDMI for picture. Use a cable like this to run sound from your audio out on your Mac to your TV's audio in. That's about all you can do.
