Mid 2010 Mac Pro, Black Screen on start up. Video works after I turn machine off, let it cool

My Mac Pro is acting up.
If I do a reset after its beenruning for a period of time I get a black screen at start up. I have tried multiple different monitor cables and nothing seems to work. It does seem to resart and I can here the start up chime but no display. If I unplug the machine and let cool for 1/2 ~ 1 hour it then turns back on with no problem.
Processor 3.33 GHz 6-Core Intel Xeon
Memory 24 GB 1333 MHz DDR3 ECC
Graphics ATI Radeon HD 5870 1024 MB
Software Mac OS X Lion 10.7.4 (11E53)
Display is the 27 inch cinema
Any ideas? Bad graphics card?

AC if you used it this once would pay for itself. Same for a good solid UPS - a good one can stop that 1/100,000 surge that takes out a modem (if you filter of course).
I've known people that never knew you could filter coax cable or dsl and we get enough severe storms it has been, not if it happens, but when.
Unlike the X1900 which had a air chamber and would cause clogging you really should not need to and be pulling it out to clean dust all that much if at all.
People have gone through 2 or 3 ATI 5770s and some 5870s due to what are probably design or bad batches especially the first months run.

MAC SLEEP BLACK SCREEN

mac sleep black screen needs cursor movement to clear

I have a variation on this issue.
We have been rolling out Lion and came accross this issue and applied the fix suggested and it works. However the new twist is that when the user logs in all their apps have shutdown (without savaing).
For security reasons our company insists that all workstations (Mac or Windows) implement account lock down after 15 mins on inactivity. So I need to find a fix for this.

My Mac Pro (2006) has suddenly stopped sending signal to the display monitor.

My Mac Pro (2006) has suddenly stopped sending signal to the display monitor. It coincided with plugging in an Epson printer via usb - while the system was running. Pretty dumb maybe? Could I have damaged the video card? Anyone ideas? Thanks

Howdy Le Batch,
I was looking into the issue you are seeing here, and came across a helpful article for this specific situation. It's named Apple computers: Troubleshooting issues with video on internal or external displays and can be found here:
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.
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 resolutionStart 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.
Regards,
Sterling

2008 MAC PRO - ORANGE Screen of Death, well death of your video card.

2008 MAC PRO - ORANGE Screen of Death, well death of your video card.
My wife's MAC PRO had this occur yesterday, here is how I solved the problem as the system was out of warrantee. System had the NVIDIA GeForce 8800 GT for the MAC.
Symptom: System starts boot as normal, see the grey apple screen, just as the desktop screen is to start, the screen turn completely orange. Attempted several reboots, holding down the diagnostic keys, re-installed the video card after cleaning, all these actions resulted with the orange screen.
Solution: Go to the Apple store and buy the NVIDIA GeForce GT 120 Graphics Upgrade Kit for Mac Pro - around $149 at time of posting. The card will work in a 2008 MAC PRO as long as you have upgraded to Requires Mac OS X v10.5.6 or later. Card has DVI and MINI Display port so I also purchased the Mini DisplayPort to DVI Adapter (you can find these online for less then the Apple adapters) to support my wife's second monitor.
Replace the NVIDIA GeForce 8800 GT with the NVIDIA GeForce GT 120 and system started right up with no issues.
Hope this helps.

Sort of falls into the "common sense" though the GT120 cost and performance, I would have recommended the ATI 5770 for $100 more is all.
What is annoying is Apple doesn't offer a 10.6.5+ DVD to boot from or a way to slipstream the ATI support drivers. Some Mac Pro (2009) can boot with 10.6.3 DVD with the ATI 5770 but in general you need 10.6.4-1/2 (the Mid-2010 build number).

Mac Mini / Boot Camp / XP Pro / Black Screen with DVI display

Boot camp partitioned the hard drive on my new Mac Mini and restarted after I clicked Start Installation, but came up to a black screen. No blue installation screen, nothing.
I downed it with the power button and unhooked the display from the DVI port. I went and got a VGA cable instead and hooked it up via the DVI/VGA adapter and started up again with the Option key. Chose the Windows XP Pro SP2 installation CD and it went through the Windows installation OK.
The trouble is this Norwood Micro HD17A (17" widescreen) looks TERRIBLE on VGA whether I run Windows or Mac OS, because there's no selection for 1280 x 768 resolution. It looks great on DVI both on Mac OS and in Windows once I get XP Pro to load.
After logging in to Windows I can unhook the VGA cable and adapter and reconnect the monitor using the DVI. The moment I do this Windows looks great, with native resolution supported and everything's fine. But this is a terribly cumbersome login procedure!
It seems that XP Pro has no trouble communicating with this display, provided I can get Windows to load. I contacted Apple Support but they say it's a problem with Windows, so I submitted a support request to Microsoft. I'm waiting for them to tell me it's a problem with Boot Camp or the firmware.
I've seen descriptions of very similar problems on other forums (123macmin.com) and here, but no solutions anywhere. Anybody know what's happening here?

Update: Microsoft says it's probably a problem with the hardware:
==========================================
Mark, I would like to explain that the issue should be related to the display card driver. We still need to contact the Apple support to verify if their machine has been tested under the XP environment when DVI or AVG is in use. This issue is related to Hardware and cannot be resolved from a Windows XP standpoint. Our Windows XP Support Team deals mainly with issues related to the Windows XP Operating System. Thus, we are not the best resource for this issue.
Please understand the problem may be beyond our support boundary and, therefore, our help to troubleshoot this issue is limited. Let’s contact the manufacturer who will be more familiar with their products. To contact them, please access the following link:

Meanwhile I sent Redmond the System Information in an NFO file. More as this develops!

Okay my Macbook Pro computer screen suddenly went black but it came back on once I clicked a key what does this mean?

I need some assistance I just bout a refurbished Macbook Pro 17 inch and i have had it for roughly 2 weeks. My computer screen suddenly went black and comes back on after I press a key. What is the matter I need help cause im starting to get upset

Hi,
is it possible that while working in photoshop, you accidentally hit this key-command?
Control+shift+eject
This instantly darkens your screen to black. When you hit any key, the screen comes back, the behaviour you describe.
(It's a handy thing when your boss comes in and you don't want him to see your "confidential information".)
Maybe there a key command in photoshop you used and you missed a key?
(Or something was pressing on the right top corner of your keyboard (the eject key) en you pressed ctrl-shift to execute some other keycommand)

Macbook Pro Black Screen (Yosemite 15" 2014)

Hey guys, I was just sitting down and opened up Skype and my macbook pro suddenly went black, just previously I had been watching stuff for a few hours on my macbook hooked up to my TV via HDMI cable. I thought to simply restart, I heard the sound chime but the screen remained black, I hooked my macbook back to the tv and everything shows up and works perfectly on the TV, i can adjust the backlit keyboard lighting, but as its through HDMI sound/brightness adjustment couldn't be done, without HDMI attempting this changes nothing, I have reset the PRAM & tried to enter safe mode which didnt seem to go into safe mode, instead staying as a black screen, i have now force shut down my laptop about 20 times with nothing working on the screen, the whole screen is black, no cursor or graphics visible, shining a light in the screen shows nothing, the apple logo behind is not lit. I have researched literally every available article on this matter that I could find but most relate somehow close to mine but with different issues such as cursor showing or external monitor not showing display, I am convinced this is something related to me pulling out the hdmi or confusing it somehow, this laptop is literally like 2 months old and I cant see how there could possibly be a hardware issue.
Thanks all for reading hope someone has an idea I haven't tried!
Specs:
Year: 2014
GPU: Intel Iris Pro
Memory: 16GB RAM
OS: Yosemite
Symptoms:
Black Screen
No Display on Macbook
Keyboard and Keyboard lighting working
External Monitor fully working through HDMI
Sound Chime and booting correctly

Just encountered this problem this morning. Here's the fix: (Relayed from another forum)
1. Shut the computer down by holding the pwr button down for 10 sec.
2. Restart the computer with a short push on the pwr button and press the shift key down at the same time until you see the progress bar start moving.
3. Once you reach the point when your screen goes dark and you see the cursor, type the first letter of the username for your computer, then hit Enter, then type your password and hit Enter.
4. After a moment you should see the spinning ball.
Apparently this is an issue with an uncompleted update, but instead of asking you for your details to complete the update the screen goes black, but the computer is still able to receive your inputs.

Yoga 2 Pro Black Screen

My Yoga 2 Pro is black screening on start up. Running Windows 8.1. On startup, the keyboard lights up, switches off and nothing on the screen - not even the Lenovo logo. Have tried one key recovery, still nothing. Also tried an external monitor and nothing on that either. Strange thing is that this first happened yesterday, and after a few restarts it suddenly started working. Put my machine to sleep, then this morning, same problem! Please, please help if you can - my only machine and need it for work - I'll be in a bad way if I have to send it in for repair.

The problem in this thread sounds almost exactly the same:
http://forums.lenovo.com/t5/Idea-Windows-based-Tablets-and/New-Yoga-2-Pro-Impossible-to-turn-screen-...
Obviously with this Comodo software, but the symptoms are similar.
I think I will try their recommendations before sending it for repair, as its probably exactly the same thing that Lenovo will do.
I also can't believe that this is a serious recurring issue otherwise EVERYONE would be returning their Yoga 2 Pros.
The fact that the screen switched off from inactivity then never turned on leads me to believe its a software problem, not hardware. At least I hope so.

Mac retina black screen

My retina display froze up when the screen saver turned on, have not had this problem before, then the screen turned black. I can see and move the mouse on the black screen, but other than that it's frozen, I'm on the forum via my iPad :(. I held the power button to crash it. Why did this happen I never expected this from a mac pro. I had nothing intensive running, only the Internet on, no downloads, just the default screensaver universe pics.

HT4904 Macbook pro black screen

Black screen shown on startup. Need help with macbook pro 13inch

Hey maine edition,
Thanks for the question. The following article may provide a resolution to your issue:
Troubleshooting: My computer won't turn on
http://support.apple.com/kb/TS1367
If your computer has power but doesn't display any video, it may have one or more of these similar symptoms when you press the power button:
- You may hear a startup chime.
- You may hear fan or drive noise.
- You may see a light from the Sleep LED (if your Mac has one).
- Pressing the Caps Lock key on the keyboard causes it to light.
If any of these display-related conditions occur, see Troubleshooting: My computer has no video instead. Otherwise, continue with this article.
Thanks,

Slideshow in Lightroom 5.5 Mac Yields Black Screen

I just discovered that the slideshow functionality in Lightroom 5.5 on my Mac yields only a black screen.
This is the case for both impromptu slideshows (CMD-Return) and the Slideshow module.
From a Google search and looking over topics in this forum, I've found other posts describing this identical problem for both Mac and Windows versions of Lightroom going back to the original introduction of Lightroom 5 over a year ago.
I've been using Lightroom on various Mac computers since the first Lightroom beta release over 10 years ago. I generally don't use the slideshow functionality of the program, so I was quite surprised to discover yesterday that it's not working in Lightroom 5.5. I originally tried to preview/play a slideshow with 100 photos--some Olympus Raw files and some Canon JPEG files. I have since replicated this problem with a test collection of 5 JPEG images.
I know that the slideshow functionality used to work back in Lightroom 3 and 4. I hadn't tried to use it in Lightroom 5.x until now, so I don't know when it became broken, but it's definitely broken now...and from reading various posts here on Adobe forums and in related non-Adobe forums, it appears that Adobe has yet to acknowledge that this problem exists...which I find surprising and disappointing.
The only work around seems to be to export a PDF slideshow from the Lightroom 5.5 Slideshow module, which does produce a full-screen slideshow PDF. But, the slideshow functionality should work directly in Lightroom, as well.
DETAILS:
Hardware: Mac Book Pro Retina -- fully loaded (2.6 GHz Intel Core I7, 16 GB RAM, Nvidia GeForce GT 750M 2048 MB graphics card, External Apple 27" Cinema Monitor connected via Thunderbolt)
OS: Mac OS X 10.9.4 Mavericks
LR Version: Lightroom Mac 5.5
Problem 1: Impromptu Slideshow (pressing CMD-Enter/Return keys from Library/Develop modules) causes:
1. spinning beachball for seconds to minutes depending on how many images are in current folder/collection
2. followed by "Preparing Preview progress bar
3. followed by entirely black screen. Pressing forwards/backwards arrows do nothing; pressing ESC or mouse click returns to Lightroom module
Problem 2: Slideshow Module - Clicking Preview button (or Preview triangle under slideshow window) causes:
1. Preparing Preview progress bar
2. followed by slideshow window turning completely black.
Pressing forwards/backwards arrows does nothing; pressing ESC or clicking mouse returns slideshow window to display of slideshow layout
Clicking the Play Slideshow button exhibits exactly the same behavior as above, except that my entire screen blacks out instead of just Lightroom's slideshow window.

I’m disappointed

Update:
Just upgraded from Lightroom Mac 5.5 to 5.6.
Per my post above, creating an impromptu slideshow (CMD-Return) or using the Slideshow module produces either a completely black preview or a completely black full-screen slideshow.
While Adobe addressed other issues and bugs in Lightroom 5.x, they apparently did not address the slideshow functionality in this release, alas....

Yoga 2 Pro - Black screen when on tablet mode

Hi,
2 weeks Yoya 2 pro out of the box, and get a black screen when reaching the tablet mode (back of the lid touching the back of the laptop base).
I try hanged the setting under power management, with no success. When reaching the tablet mode, I get the same result as closing the lid in laptop mode.
I connect my Yoga 2 to a TV through the HDMI and can see the screen and interact with the black screen (not easy to touch the right spot).
My bios is updated and I have Windows 8.1.
Any suggestion???

I found the answer to my problem at
http://forums.lenovo.com/t5/Idea-Windows-based-Tablets-and/Yoga-2-Bios-Update-Crash/m-p/1322487/high...
Now that I found that post I do recall the instructions telling me to turn it off manually when I updated the bios earlier this year. However, the current instructions do not mention it at all, perhaps they should be updated?
