Satellite A100-646 and external monitor shows black screen

Hello to everybody,
I have a similar problem with A100-646 (bought in Italy). Laptop's LCD and external monitor shows black screen but system boots without other problem. When laptop is not used for a long time (half a year) it work for one week without any problem.
Unfortunately, there is no proper service in a place where I live. Perhaps, there is a problem with power supply.
Is there other idea? Does anybody have a service manual? ([email protected])

It is not easy to find shop where you can order original and new hardware components.
Best source for such parts is definitely eBay where you can buy used but well working components.
Upgrade? You must know that upgrade on mobile computers is not the same as on desktops. Cooling possibilities are not the best and each notebook model has optimized cooling system for original parts. So new graphic card can be more powerful and produce more heat and it is definitely not good for your notebook. So best thing you can do is to replace it with original part.

External monitor shows black screen

Hey fella's,
I have an early 2011, 11'' Macbook Pro running Yosemite 10.10.1, which I've been hooking up to an IPS226 LG Flatron external monitor.
It did a number on me last week: the external monitor decided to show only a completely black screen. Like it's in power saving mode, except it isn't: the Mac recognises its existence, the laptop's monitor becomes a secondary screen. When I unplug the external monitor, it says "switching to power saving mode" and then goes black again...
Here's the kicker: I tried hooking it up to other laptops using different cables (mine is HDMI, so I tried VGA to another laptop) - worked like a charm. Then, when I plugged mine back in, also worked! Until today. Now it's happened again. What sorcery is this?
Thanks!

Hi Polindrom,
To troubleshoot this issue where the external display you're using with your Mac appears blank, please follow the directions outlined below.
No video or no signal, image distortion, "snow," or flickering
Check connections
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the system
You can reset the Mac's parameter RAM and SMC.Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.

External monitor showing black screen

I just got an LG external monitor with DVI cable and the mini-DVI to DVI adapter. When I plug it in, my MacBook sees the display but nothing shows up on the display. Any ideas as to what the issue might be? Could it be the port on my MacBook? This is the second display I've tried and am having the same issue, so I'm thinking it's my computer. Help!!!

I have been having similar problems with an LG monitor too but it is resolution dependent. Could there be some issue with LG monitors and Macs? I could go the VGA route too but isn't that inferior picture quality?

Hi, firetiger.... i have the EXACT same problem!!! i have the same Macbook aluminum unibody screen also. I have no idea how to fix it. I'm also out of warranty and i've tried everything... resetting the pram, trying to restart in safe mode, trying to boot from a cd... .NOTHING WORKS!!! i can still control brightness itself but ive never tried attaching to an external monitor. I know everything is loaded correctly... i just don't know whats wrong. If you have any ideas.. please let me know. Also, I think apple will fix the macbook pros with a similar issue for free http://support.apple.com/kb/TS2377 but i know this doesnt apply for me. hopefully they work something out because I really love that computer!!!

Why is it that when I plug my Macbook Pro to an external monitor, the external monitor turns black and shows the mouse only

Why is it that when I plug my Macbook Pro to an external monitor, the external monitor turns black and shows the mouse only

Hi, yes preferences sees there is a second display it recognises what make of monitor it is etc but I just get a blank blue screen on the monitor when I change it to the hdmi setting! I have tried with mirroring on and off, rearranging the displays in the preference window and lots of different resolution settings but with no difference.
An old MacBook connects fine so the monitor and hdmi port must be okay. I'm sure we have used the cable before but it could have been with the previous MacBook Air. The current one I'm using is a mid 2011 version running lion and is (according to software update) all up to date.
Any thoughts or help would be appreciated!

Viewer and External Monitor doesn't playback at same time

When watching clips in the viewer window, they playback fine. But on my external monitor, it only shows the first frame from when it's played. when I stop playback, the external monitor then shows the last frame the Viewer window is stopped on. How can I fix it so that the viewer and external monitor playback the clip at the same time?
At the moment we're digitizing footage with the Offline RT Photo JPEG codec set to 75% quality.
A few days ago we were digitizing footage at 35% quality and that footage plays back fine. We moved to 75% quality at the editor's request. A few days ago we had created a few sample 75% quality tests for the editor to view. I loaded those clips into Final Cut right now and they playback fine as well. So it's all of a sudden just these new clips created yesterday :S.

Yes.
Forgot to mention that the timeline plays all the footage back properly on both the canvas window and the external monitor. Sorry for not mentioning that sooner.
More discoveries! The playback 'freeze' only happens if I open a clip from the browser into the viewer. If I open a clip from the timeline into the viewer, it plays-back fine!

My mac won't recognize an external monitor. The screen Goes Blue Once, then goes blue again and the second monitor just turns off. I am using an HDMI adapter to a visio TV. I also have my xbox on the tv. Can anyone Help??

Lol, figured out the first part. Just for those who may be searching, when you click on the Display Preferences, and click on the arraingment tab... it not only shows where your two screens will be displayed, but the WHITE BAR at the top of one screen is the dock/toolbar. Click and hold to grab this and just slide it over to the screen you'd like it to be on.
You have to release it IN the screen box, not on top of it... and it should pop right over to the new (or old) screen. At any rate, you can put the dock on either (or any) screen that you prefer.
I am thinking of ordering more of these. Lol. 3 monitor setup seems like it would be crazy good.
Still looking for the answer to keeping the new 16" screen on the right without switching between screen #s with that... not expose... Lion feature.
Thanks. Hope my other question has an answer out here.

Viewing footage on desktop and external monitor at same time

Maybe i'm missing something, but is there any way to view footage simultaneously on your desktop monitor and your external broadcast monitor (via blackmagic output)?
Right now when I enable mercury transmit, the viewer within speedgrade goes to grey and I can only see the footage on the external monitor. This makes it impossible to draw custom shapes around objects (rather than just use the stock circle masks) which I use quite a bit...I would like to have the view on both monitors like I have in resolve.
If this isn't possible, is there a quick shortcut to toggle mercury transmit on and off without having to go into the settings menu?
Any help would be appreciated...I am enjoying a lot of the controls that are in speedgrade but there are some workflow hurdles that I need to get over in order to be able to use effectively in client sessions from time to time.
Thanks!

I waited expectantly and patiently for Adobe to enable Mercury Transmit in SG and to be able to make use of my BM card and external monitor.
O.K we got it in CC2014.1...but it is either Mercury Transmit or Dual Display!
I think this half-arsed solution is an absolute fail that we cant use desktop and an external monitor simultaneously.
Has anyone on the SG team actually been in a real world CC and Grade Suite?
At least we got consistency with the blue color scheme if not how Mercury Transmit works across the suite of apps.

My lenovo g510 shows black screen every time I power it on but the power lights are on .

Every time I power on my laptop it shows black screen.but fan is running and power lights are on. After detaching and reattaching battery several times onece screen turns on and laptop then works smoothly.but after shutting it down again on next day same problem persists. I have already tried power drain out method.but on the next go same problems arises.what to do.

Hi Anish1,
Welcome to the Forums
As per the query we understood that you are facing issue with black screen in your Lenovo G510 laptop.
As you have mentioned that black screen when turned on, can you hear the windows login sound?
Remove the battery and connect only adapter and check for the issue also connect only battery and check for the issue.
Connect an external monitor and check if the display appears in the external monitor then its a issue with the LCD, if there is no display in the external monitor then it might be issue with the motherboard, hence suggest you to visit the nearest authorised service centre.
Click here for the service centre and select your region.

I have installed an app : Birdfield guide in my iPhone 4. But the app is not working after installation. It shows black screen when opened. I need suggestions to make it work or the reasons for not working.

Yes TeeKnows, try deleting it and download it again. After finished installation if still shows black screen delete it out off 'running apps' by double tapping the home button and swipe it off. If still shows black screen then try fully turning off your iPad (holding the sleep button) and turn back on again.
I hope I helped
thanks

Mov videos show black screen after latest update (idvd, iweb)

Hi MacUsers,
I am facing a severe problem after updating my MacBook Pro (Mac OS X 10.6.8) with iDVD 7.1.2 and the iWeb Update. I opened a keynote'09 presentation and encountered that most videos do not show up or just show a black box. Then I tried to open the original mov videos with QuickTime Player 10 and 7 but also black screen. Everything worked perfectly before the update. Any ideas how to solve the problem? It is urgent because I have to give a presentation tomorrow. By the way, using VLC works fine, but this does not help me with keynote. Thanks for any answers.

Here is a comparable problem described in an older thread:
https://discussions.apple.com/thread/2259769
It seems that there is still a problem with QuickTime. All other players such as MplayerX, VLC or mediAvatar can handle the mov videos (Apple Motion Jpeg A). Is there a solution?
