Screen black after opening

Hello,
I was wondering if anyone could help me with a problem that I'm having with my Mac Book Pro. I hardly ever turn off my computer and usually just close so basically the computer is sleeping. When I go to open my computer I have a black screen and the sleep light that blinks is still on. I press and hold the shutdown bottom to turn it off and turn it back on and everything is fine. The problem doesn't happen all the time either. I was wondering anyone had any idea what was going on.

It can also mean that your computer is looking for a far-away network if you are using wireless networking when the problem occurs.
When my MBP (running 10.5 at the time) started that same behavior, I found that I had accumulated a huge list of wireless networks on my travels. Reviewing the system log, I found my computer was trying to connect to one, a hotel network to which I had connected weeks before and miles away.
Here's how I fixed it:
1) Open System Preferences and select "Network."
2) Be sure "Airport" is selected in the left side of that preference pane.
3) Click the "Advanced" button. If the next screen does not have the "Airport" tab selected, select it. There should be a window with a list of networks.
4) Use the + and - buttons below to remove any networks you have accumulated that are not needed. Example: on mine, there are now only two networks--our home network and the one at a museum where I volunteer.
5) Once you'd cleaned off the list to the bare necessities, uncheck the option labeled, "Remember any network this computer has joined." This will not prevent you from using other networks on later travels but will prevent them building up and creating problems.
That completely cured my wake-from-sleep problems. and other have said it worked for them, too.

Screen black after sleep startup and won't turn off w/ power button?

I have a Powerbook G4 and hardly ever turn it off, till lately.
My computer started turning itself off after I would open it and wake it up from sleep mode. It would flash the screen quickly and then go black. All efforts to turn it off with the power button failed. I had to remove the battery and disconnect the power cord for about 2 minutes until it eventually shut down. I have not had this issue since I have been turning it off after every use, but was wondering if this was a sign that something was going out on my computer?
Thanks!

Try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod.
There's more to try but let's go a bit at a time.

Screen Black after waking from sleep mode (after 10.4.11 update)

This issue has happened before with an earlier update (10.3.8 Delta fixed the issue originally), and I suspect it is the same with this current update.
Has anyone else had this problem with the new update and has there been a patch released to fix the problem yet? Hopefully we can get an update soon.

This happens every so often to my 12" Aluminium PowerBook after sleeping (black screen, hard drive spinning away) and after trying every possible key combination and nothing helping, I'm usually left with the usual last resort, which is a hard restart. Of course that remedies the problem short term but unfortunately, only until the next time it happens. For me, it has been an issue since I bought it and is not affected by the OS.
I am wondering if it has anything to do with the clasp not working properly when the lid is closed. Sometimes I get the sleeping light, sometimes not - unless I play with the lid until it clicks shut. Then the light appears. Importantly, when the sleeping light appears, the machine always wakes properly with the lid opening. But I have noticed that when the light does not come on and I haven't bothered to shut it down properly, that is when the problem occurs. Which makes me wonder if rather than going into sleep mode it is actually going into hibernation mode due to non use? I haven't a clue but perhaps someone here knows far more about such things than myself?

Viewer Screen Black after Mavericks and Apertutre updates

Hello All, I have updated to Mavericks on my home iMac that is a few years old, and a new one at work that is 6 months old. Everything was fine and then I updated to Aperture 3.5. Now on BOTH machines, I am able to see all of my images in browser view fine. In split view the images in the filmstrip at the bottom of the screen are still fine, but the main image being viewed is black. In full viewer the image is completely black. It will indicate loading, show all photo info at the bottom of the viewer, but load as a black image.I can use an external editor PS5 without issue. I have completed the three step for the library first aid. When opening Aperture, the image may flash on the screen for a split second, and then show as black.
Apple support only seemed interested in having me sign up for Apple Care, even though this is a software bug, so this left me a bit unhappy. As a photographer that really needs Aperture running correctly, I'm at a standstill and may need to move to Adobe as an emergency solution.

Weird it is happening on two separate machines. Was the library from one machine copied to the other? What camera and are the originals Raw?
Try making a new empty library and import a few images into it, what happens? If it still fails there try running as a new user or from the Guest account if you have that enabled. Start Aperture and add a few images to a new library, what happens?
Also try looking at one of the original files in Preview, is it OK there?

Screen black after mountain lion install

After install, the screen connected to the original video card is black, other 2 screens connected to evga gtx 285 are ok. do i need a new video card?

I have the same problem over here!
I installed the ML and after that, my BRAND NEW MacBook Pro with Retina Display rebooted.
The only problem is that the display is black! I tried to reboot a few times holding the power button with no success, only to have an idea. I connected an HDMI cable to my TV and I could see the login screen and work nice.
But c'mon, i bought a laptop to take it wherever i want. Now I can only get the image on my TV with the HDMI cable.
Does anyone knows how to put the image back on the screen? I tried everything from rebooting and taking out the HDMI cable to searching on the Settings>Monitors for something..
Thank you in advance for any answer.

Screen black after MacBook Air

I installed MacBook Air & Pro Update 2.0 on my 2012 13" MacAir and I find that sometimes when the Air is idle and the screen blanks (energy saver) it stays black and doesn’t tuen on again when I press a key. The only way to recover is a power cycle.
This happened twice. I turned off the option to turb off the screen when idle only enabling the scree saver and it hasn't happened since.
So there is an issue with the energy saver after applying this update.
Anybody seen this???

Yes, happens to me. And other bad things.
I read somewhere that Apple has pulled the update. Too late for those of us that installed it and are having problems.

My iPhone turns screen black after a call ....

The only way to have the normal screen again is by locking and unlocking the iPhone...
My iphone as 1 month and a couple of weeks ... I have sent the iphone back to the operator, but it returned the same way...
I have done a soft reset and a total system restore from itunes...
Getting out of resolutions...
What can i do?
Thanks

Thanks for replying ... Its not normal what my iPhone is doing .... Normal is after a call the screen goes back to normal or like you said back to the contact page or keypad ... When it stays black, it remains black ...not even the home button does nothing about it , only by pushing the power button it comes back to normal.
But thanks anyway.

T400 LCD screen black after replecement

History - T400 (2767-31U), Win 7.
LCD screen broken due to a drop. Laptop still worked with an external monitor via VGA slot and I ordered a replacement LCD.
The replacement finally (used-off ebay) arrived and I followed the HMM manual and replaced the LCD. But it still does not work. I can continue to use the ext monitor without any issues. The replacement LCD was the full assembly not just the LCD screen.
Here is what I noticed:
1. When booting up, I see the Thinkpad logo very very faintly before it goes fully black again.
2. All the LCD panel lights work fine - Wireless, BT, HDD, Battery, Power etc etc including the reading light.
3. The laptop recognizes when I open and close the lid and switches on the ext monitor accordingly.
Here is what I did (I followed the HMM to the detail):
4. When I replaced the LCD, I noticed that the original LCD had 2 black wires insulated at the ends originating from the bottom left area of the LCD that were not actually plugged into any area of the MB. I did the same on the replacement LCD and left them as it is. I don't even know what these are.
5. I connected the other 3 wires(white, grey and black) and the main connector as the original LCD/HMM.
6. I uninstalled the display drivers and restarted and Win 7 automatically installed the drivers again.
7. The Most important part - The original LCD when powered on, DID have backlight showing me the mangled area of the screen so I know it worked before replacement.
I have read quite a bit of posts regarding T400 black screen issues, pointing me towards a faulty MB, blown fuse or faulty inverter. I know the replacement is an exact replica of the original LCD.
Could it be that I didn't connect the wires correctly to their respective slots on the MB?
Any inputs would be highly appreciated.
Edit:
Solved!
Go to Solution.

Welcome to the forum!
Do I understand correctly that you bought a complete new LCD Assembly? Do you have proof from the seller that it was working properly before you bought it?
Can you see a picture if you use a torchlight over the panel?
A faint dark picture could be a defective LCD cable, inverter/LED card or a defective LCD backlight. Since you see a picture I would rule out a motherboard fuse problem.

MacBook (2007) screen black after reboot/shutdown

Hi all I hope you can help me.
I have a MacBook C2D 2GHz, 2gigs of ram from mid 2007.
I cant remember when the problem appeared but maybe 6 months ago.
Every time my macbook is rebootet or shutdown after an update or if it runs out of battery the screen remains black. The sleep light stays constant on but the chime is played and cd drive makes it usual short start up sound.
I can hear the harddrive working and after maby 30 sec, the screen comes on but its all whiteish with a black stripe down in the right side and stays like this, other times the screen comes on with the desktop but flashing/bounching
If I hold down the power button to kill it off and hit the powerbutton again the same thing happens.
The way I fix it is to power off, take out the battery for about 10 sec. put it back in and hold the trackpad button down or put two fingers on the trackpadand power on, it starts normal with the grey screen and the littel apple logo and boot normally to the desktop. But today today it took me 7 atempts with the above method before it worked.
Is my screen about to die or is it software related.

I have the same problem and I dont think I had this happen until 2 weeks ago and I've had the latop since the last week of August. I've also had the problem crop up when I had the laptop go to sleep while watching a video online and when I tried to wake the laptop back from sleep, I get the blank screen with the cursor. My system is a Macbook air 11" 2013 1.3 Ghz with 4gb ram and 256 gb SSD. I also have a 15 MBPro and have not encountered this problem. Is this anyway related to the recent update that OSX was pushing for the upcoming Maverick update?

Screen black after booting (backlight still on)

My iBook g4 12" 1.33 Ghz doesn't want to boot into the system.
1. Start computer (chime sound)
2. Apple logo on grey background appears
3. Spinning wheel below Logo appears
4. Screen flicker, big vertical zigzag appears, black screen (backlight is on)
5. Shift key work (led on/off)
6. Num Lock key works (led on/off)
7. no responses with any other keys on keyboard
What I tried so far
1. Reset PRAM & NVRAM & PMU
2. Put original installer disc in, press C start from DVD - same as above happens
3. Boot from external hard drive with operating system over Firewire - same as above happens
4. Mounted iBook drive as external drive with target mode - Other computer boots fine with iBook drive
5. Attached an external monitor, which doesn't get a signal
6. Run Hardware test over DVD - Diagnostics all fine (Screen fine all the time, running through all diagnostics)
7. Tried pressing on the graphic chip, as some forum entries suggest - didn't change anything
8. Start in Safe mode with shift key - no indication that in safe mode, same faults
9. Start in single-mode (see image http://www.somethingonline.org/dl/pb/singlemode.jpg)
Don't know what else to try
Any help appreciated

Since you're able to boot into single user mode the run fsck, so at the command line type the following:
/sbin/fsck -fy <then press return>
Then try to reboot, if it still does not help try booting into Open Firmware and manually reset the PRAM, hey it's worth a try!
Power-on Mac and immediately press and hold "CommandOption+OF" keys simultaneously until the ok prompt appears. At the ok prompt type the following:
reset-nvram <then press return>
reset-all <then press return>
The reset all should reboot the Mac if all was reset ok.
Hope this helps.

15Inch G4 laptop screen black after sleep mode

I turned on the laptop and it came up with the log in mode. I realized that I didn't have the log in password so I waited for the owner to come back. 3 hours later I got the password and tried to log in again. but the screen was just black. The light in the front where you flip open the screen was on, pulsating. I tried to hold down the power button for a couple of seconds (15-10 seconds) but nothing happens. I can't start it again, I can't shut it down? am I missing something?
On the bottom of the computer I saw a row of 5 lights. 4 to 5 are on most of the time. I assume that signifies the harddrive is working...? There's also a button next to it. What is that button? Is it some sort of reset button? Should I press that one?
Any help appreciated.
thanks
Power Book G4 Mac OS X (10.4.3)

Hi S K5,
The lights your seeing on the bottom of the PB are actually on the battery. They indicate charge status. The 'button' next to it that I think you are referring to is the release catch for the battery. If you can't login and the PB is not responding when you press the power button you can try pulling the AC power adaptor then removing the battery, however I would at least inform the owner (if you haven't done so already) of this issue before proceeding further. Also, you'll need a dime or something small enough to fit in the slot on the 'button' next to the battery. Turn it in the direction of the 'open' lock icon to release the battery. Then reinsert the battery and try restarting the 'book.
Jrsy

MBP screen black after using DVI to HDMI cable

Over a week ago I attempted to connect my MBP 2007 model to my samsung television with HDMI in. I have used this cable before but always have trouble getting it to work with this TV and my computer.
Well, I plugged it in and the screen on my computer went black and the image failed to appear on the TV despite tinkering with the settings.
When I unplugged the cable The image would not restore to my screen so I restarted it...same back screen. I took the battery out and pushed the power button to drain the juice and put it back in. No luck. Please help. Any usea? Seems to just be a software problem.
Sent from my iPhone, sigh
