G780 display goes black every 3 seconds

Once machine has been on for about 20 minutes, screen goes black every 3 seconds

Could be a chipset or display driver issue. Try uninstalling and re-installing those drivers before doing anything else.
Otherwise, get a repair ticket in with Lenovo before it's too late. Sadly, it seems like this model is just hampered with issues. Hope you get your issue resolved.

Display goes black randomly

I purchased the notebook barely 16 days ago, and after a few days I noticed that the display goes black for a second or two randomly i.e it doesn't happen while holding the notebook in any certain way or something. The dislay goes black anywhere while playing games, music, videos or simply anytime. Also now there's some flickering in the lower part of the display. It happens with no approx time gap. I asked HP's Chat Support to help me out of this, they tried to uninstall and have a clean install of display drivers, that didnt work.Then they said they'll assign the nearest Physical service centre for an onsite visit and that some one will contact me, but waiting since almost 4-5 days this didnt happen. For the past two days I regularly ask HP's Support team about the promised visit but they keep on saying that today you'll recieve a call positively. The problem has escalated to such an extent that it interferes with my studies, work and daily use. This all has cost me alot of time and money and it's all due to your faulty product and carelessness. I would like you to help me in this regard, asap, if it is at all possible for you !! Edit : Before you ask, everything's updated to it's latest version. and I don't have an external Monitor.

Mac screen goes black every 2-3 minutes, returns after 1 second, Mavericks

My MAC, updated to Mavericks, screen goes black every 2-3 minutes, for one second, then returns. Has anyone experienced this? How should I correct it?

SOLVED!!!!!
SO I did some more digging around and read ATI cards seem to overheat easily. I knew the fan was working, but after closer inspection I realised there was ALOT of built up dust on the card and clogging the fan and airflow. Blew it out with alot of compressed air, stuck it back in the Mac and BAM...no black screens. I tested it by streaming 6 video sources...doing 2 screen captures at once as well as watching a HD movie in fullscreen. Did all this for 30 minutes and no crashes. I also downloaded an app to monitor the temps inside the computer and the expansion bay stays at 41 degrees. No clue what it was before but obviously it was hotter than that. So my problem is solved! Funny that 10.7.5 made the card work harder. I wonder if its off loading some CPU stuff to the GPU for processing more than 10.7.4 so its just working a bit harder and so it heats up faster....

Audio not working / Video flashes to black every ~5 seconds

Hi. For some reason, when we turn on our TV as of late, every channel is having this issue where upon turning on, the video will flash to black every 5 seconds or so, and there is no audio. The only thing that solves the problem is unplugging and replugging in the STB (Motorola QIP7232-2).
I've replaced the HDMI cable with a new one. No dice.
Netflix via the X360 works without a hitch, so it's not the TV.
Scanning for repair/errors on the STB comes back with no issues detected.
Any reason why this is happening, and is anyone else experiencing this?

I am having the same issue. Unplugging and repowering on resolve the issue, also disconnecting and reconnecting the HDMI cable fixes it. Output from the 7232 goes to a Sony Google TV device. I also have DirecTV and never had this issue. Seems like an HDMI switching problem. Is there an easier way to reset the 7232 than just unplugging it? Or - better yet - what's the cause and how do I resolve?
Here are some troubleshooting steps you can try on your own for the problematic STB.
From your FiOS TV remote, go to:
Menu -- Customer Support -- In Home Agent -- Reboot STB
Menu -- Customer Support -- In Home Agent -- Set Top Box Auto-Correction

Run iPhoto slideshow on 2nd display without 1st display going black?

Hi there,
I can't seem to find a clear answer on this one. I have just connected a 2nd display to my mac mini via the thunderbolt connection. When I put iPhoto 11 onto the 2nd display desktop and run a slideshow it plays on the 2nd screen but my 1st screen goes black, which isnt ideal as I want to be able to carry on working on my 1st screen.
Is iPhoto 11 able to run a slideshow on a 2nd display without 1st display going black? If not, is there a way around this by using other software?
I have the 2nd display set up in extended mode not mirror.
I am running OSX 10.9.2.
Many thanks,
Andy.

Is iPhoto 11 able to run a slideshow on a 2nd display without 1st display going black?
No.
There may well be, but it's not possible with Aperture either.
Alternatives to iPhoto's slideshow include:
iMovie is on every Mac sold.
Others, in order of price:
PhotoPresenter $29
PhotoToMovie $49.95
PulpMotion $129
FotoMagico $29 (Home version) ($149 Pro version, which includes PhotoPresenter)
Final Cut Pro X $299
It's difficult to compare these apps. They have differences in capability - some are driven off templates. some aren't. Some have a wider variety of transitions. Others will have excellent audio controls. It's worth checking them out to see what meets your needs. However, there is no doubt that Final Cut Pro X is the most capable app of them all. You get what you pay for.

I have a macbook connected to LED cinema display. The display started to flicker. The display turns black for a second or two. Sometimes I restart macbook and display. Sometimes it helps.

Cinema display goes black upon resolution change in Windows XP

Greetings
Earlier today, I updated my ATI X1600 Radeon to the latest Windows Catalyst drivers and to the Catalyst Control Center from ATI. Even since, whenever a Windows application (games, in this case) tries to change the resolution on my external Apple Cinema Display (designated as the main monitor in the ATI Catalyst Control Center, with the MacBook Pro display disabled), the display goes black, and the monitor power lamp starts to flash.
If I unplug the external Cinema Display from my MacBook Pro, my MacBook Pro display activates, and displays whatever it is I was trying to launch, so the problems is somehow related to the Cinema Display, even if the new drivers are causing it.
This happens regardless of my Catalyst Control Center settings, such as scaling the lower resolution to fit the screen, or keeping it the original size, with black borders around. The problem does not occur when I launch games using 1600 x 1024, the Cinema Display's native resolution.
Any ideas what might be causing it, and how to resolve it?

Update on my situation: when I tried to change the resolution manually in Windows, I encountered the same problem. Now, whenever I connect the Cinema Display to my MacBook Pro, the same thing occurs: the screen goes black, and the power lamp starts flashing, even though I've changed back to 1600 x 1024.

MacBook Pro retina display goes black while outputting video through HDMI to external monitor??

I frequently connect my MacBook Pro to my 42inch Panasonic TV to watch movies/videos. I use VLC media player for all my playback. The problem I'm running into is that when I put VLC media player into fullscreen mode on my external display, my retina display goes black (I can still see the finder bar at the top and when I mouse down the dock appears but the rest of the display shows all black. If I click on Safari it will open but I can't see it on my MacBook display unless I take the external display out of fullscreen mode.
I would still like to be able to do things on my MacBook while video is playing. I've played around with the display settings but they're pretty limited and I can't figure out how to get it to work the way I'd like. I've seen people having up to 3 or 4 displays hooked up, I'm just trying to hookup one. I would consider this a severe limitation of OS X if I'm not able to separately manage the displays. Hopefully there is a setting or something I'm just not seeing. Thanks.

Yeah, fullscreen mode still doesn't play nice with multiple monitors. The common workaround is to stretch the window out to the edges of the screen instead of using actual fullscreen mode.

Hello QuinnDev,
Thank you for posting in the Apple Support Communities. It sounds like you are trying to use your MacBook Pro with a Thunderbolt Display in closed clamshell mode (MacBook Pro closed), but sometimes the display doesn't stay on. I found an article that talks about closed clamshell mode. You would have to fulfill the following requirements to use your display this way:
Requirements for closed display mode:
Power adapter
External keyboard, mouse, or trackpad
External display
You can find all the steps and the full article here:

How to display screen saver every 10 seconds ?

I want to display Screen Saver every 10 seconds as long as the user doesn't make anything on his computer.
I did that :-
WHEN-NEW-FORM-INSTANCE
declare
     t timer;
begin
     t:= create_timer('Hany',10000,repeat);
end;
WHEN-TIMER-EXPIRED
if :System.MODE = 'NORMAL' then
     Host('C:\WINDOWS\system32\ssmypics.scr');
End if;
but in RunTime the Screen Saver's Setting appear not the Screen Saver itself ..... like shown below :-
http://img118.imageshack.us/img118/245/errorv.png
that's seems weird because when I run the Screen Saver directly from Start>>RUN :-
C:\WINDOWS\system32\ssmypics.scr
it is working nice without appearing of the setting.
so, what's went wrong ????
I attached the fmb file to have a look for it if you like:-

Edited by: HanyFreedom on Apr 14, 2009 3:40 PM

There is a built-in screensaver in windows, why rebuilt that functionality on your own? If you really need it, try
HOST('cmd /c C:\WINDOWS\system32\ssmypics.scr');I assume that you are using forms 6i? For in 10g this will now work on the client-side, because HOST is executed on the app-server.

>> Boot your Mac in safe mode (press Shift key during boot) and check if it happens
I tried booting in safe mode and tried using MAC for 15-20 minutes. It didn't happen in safe mode.
Can you think of what can be the real issue and also what could be the solution?

Apple TV stops streaming via AirPlay when iPhone 6 Display goes black

Hi,
when my iPhone gets locked and the Display goes black (standby) after 2 Minutes, my AirPlay stream to my Apple TV 3. Gen stops playing. Only when i set the standby/lock time time to never instead of 2 Minutes (and the screen is on all the time) the Stream wont stop.
Sometimes the stream does not stop, wenn my iPhone Screen goes black.
This also happens with an iPad Mini or using an Lightning to HDMI Adapter instead the Apple TV.
I have no idea why.
Please help.
Best regards
Sebastian

On a sidenote, I also have an ipad and normally homesharing with the ipad works fine, but after having an apple tv incident, I have to restart the mac for homesharing to work with the ipad
