Screen remains black after power on

Brand new MacBook Pro 17" Unibody. I powered down last night and this morning on power up the screen remained blank (no visible faint displays). Keyboard backlight was on. Startup "noise" normal.
Battery was fully charged when shutdown.
Power cycled several times with no success. Removed all attachments including the power cord and after several attempts it finally powered on with a good screen display.
VERY frustrating experience. I have older 15" MBP and an iMAC and have never experienced this before.
Is there a patch/fix for this? Running 10.7.1 factory installed OS.
Is there some recourse to this? Should I take MBP to Genius desk? Can they investigate/eliminate the problem?

My 2008 15" macbook pro would not start up. After pushing the power button, the startup tone sounded, but kept repeating as if something was jammed. Screen remained black with no logo nor messages. Pls help.

Now that you mentioned it, that might be the source of the problem. Something was definitely wrong with my graphics card before the incident happened. You mean that particular batch of graphics cards had some inherent issues, right? I went to the genius bar, and the 'genius' there, without trying to diagnose the problem properly, just adviced me to buy a new mbp! He said Apple will no longer try to fix or touch macs older than 5 yrs. Mine is 5.5 yrs old...

TS3474 My nano will not power on when fully charged, screen remains black.

Bought early 2012, no idea what generation it is. When connected to the stereo, the screen illuminates and nano works with stereo controls. When I try to take the nano for a run, when holding the power button down the screen remains black and no amount of touching the screen will produce an image or any sound. Any ideas about troubleshooting the black screen when powering up un-connected?

Hello gatormother,
Thank you for using Apple Support Communities.

Will not turn on or screen remains dark
Connect iPod to power for at least ten minutes to ensure that the battery has enough charge to allow iPod to turn on.
If iPod does not turn on after ten minutes, try resetting it while it is still connected to power. Reset the iPod by holding down the Sleep/Wake button and the Home button for at least six seconds or until you see the Apple logo appear.
If the Apple logo appears on the display, connect iPod to a computer and verify that it appears in iTunes and can play music. If iPod appears in iTunes and can play music, no further troubleshooting is needed.
If the screen remains dark and will not turn on, then your iPod may need service.
Have a nice day,

Computer wakes from sleep but screen remains black even after restart

So, I installed SL yesterday and everything seemed fine. Last night, I closed my computer's monitor (putting it to sleep) for the night. This morning, when I opened it, the screen was black. I could not see anything, so I just restarted the computer.
On restart, the screen remained black.
After some experimentation, I realized that the computer was actually running, but I just couldn't see anything. So, I typed my password - screen was still black.
I then pressed the power button and enter - shutting down the computer properly.
After it shut down, I turned it on and the screen came on as normal...
What's going on here?
I checked some other threads and there was some potential issue with the iphoto screensaver, but I am not sure if that is the case here or not.
Any thoughts on how to fix this or prevent it form happening in the future?

I just had a similar thing occur. After resetting the pram the screen came back on.
I had noticed some problems with the hot corners for sleep mode earlier so I have deactivated them now to see if this was the problem. The only other thing I can think of is the recent Java update. I installed it right before the problem occurred.

MacBook Pro 2008 not turning on, no sign of power and screen remains black

I have a MacBook Pro 2008.
It was working fine until when one morning i wanted to turn it on as usual only to find out that it can not power on.
When i press the power-on button, i can hear the hard disk spinning but no display, the screen remains black like not getting power.
No beep sound when tried to boot without RAM installed.
The battery and the Charger worked fine when tested with another computer.
The RAM works fine when tested with another Computer too.
What could be wrong with my computer, i hope it is not the board that is dead.
How can i overcome this problem?

Op Charles,
You can try a SMC reset:

Follow directions for a battery that applies to your machine.

You can check these as well
It sounds as thogh the the GPU may be dead, you can take it in to an Apple Genius (make an appointment) they will disgnose it for free and give you your options.

IMac g5 screen remains black when turning on

My iMac 2.0 gz ppc g5 froze up while net surfing. I turned off power strip and when I turned computer back on all I hear is the fan running, the power white light is on but the screen remains black. Am I in some weird sleep mode? Or worse? I' m running 10.5.8

Try rebooting in Safe mode:
To start up into Safe Mode (to "Safe Boot"), do this:
   1. Be sure the computer is shut down.
   2. Press the power button.
   3. Immediately after you hear the startup tone, press and hold the Shift key.
      Tip: The Shift key should be held as soon as possible after the startup tone but not before.
   4. Release the Shift key when you see the gray Apple and progress indicator (looks like a spinning gear).
During the startup in Mac OS X 10.2 through 10.3.9, you will see "Safe Boot" on the Mac OS X startup screen.
During the startup in Mac OS X 10.4 or later, you will see "Safe Boot" on the login window, which appears even if you normally log in automatically.
To leave Safe Mode in any version of Mac OS X, restart the computer normally, without holding any keys during startup.

6th generation iPod nano automatically turns off when I push het sleep/wake button or when screen turns black after a while. How can I solve this ?

My 6th generation iPod nano automatically turns off (=stops the music) when I push het sleep/wake button or when screen turns black for power saving mode. Does anyone know how to solve this ?
I have already tried resetting, connecting to PC/iTunes to check the software version, turning off/on, I don't have any inspiration anymore.
Thanks for your suggestions!

Hi VeerleD,
If your iPod touch unexpectedly powers off, you may want to use the steps in this article to troubleshoot -
iPhone: Hardware troubleshooting (The steps apply for the iPod touch) -
Specifically -
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Thanks for using Apple Support Communities.

New ipod nano 6th generation used 3 times. Screen remains black despite a full reset. Something special to do ?

Hi, I just bought a new ipod nano and used it 3 times. Today it did not work and I first believed that the battery was too low. I connected the device to the mac. Sync worked well and charge indicator as well. Nevertheless, the screen remained black. I therefore tried to reset the device and after the resetting, the screen remains as black as before. Any solution ? thanks and regards

If it does not get enough juice from the USB port, it will not charge.
You should NOT connect it to a USB hub. Connect it directly to the computer. If you use a desktop computer, use one of the ports on the back, not one on the front, which tend to be lower power.
You say you are using a macbook, which tend to be better about power. Make sure you don't have any settings that turn off power to the usb ports when the computer goes to sleep. Check your power settings in the settings screen.

IMac G5 isight not booting, screen remains black & fans start

Hello,
The iMac in question is a 2.1 G5 20" screen with iSight. It has worked perfectly with no problems up until recently, now when I go to switch on the chime sounds, the screen remains black and after about a minute the fans startup.
I have attempted to reset the SMU and PRAM to no avail.
I did manage (after several attempts) to boot into Target Mode with another mac connected by Firewire. The hard drive shows up and all the files seem to be there. I scanned the drive with TectTool Pro and repaired permissions, I also used Disk Warrior to rebuild the drive. Still the problem persists.
Tried to boot from CD but so far this has been unsuccessfull.
I have read of people having similar problems but have yet to find a working solution but I'm hoping there is one out there as the iMac was working wonderfully right up until this problem!
Thanks in advance

It sounds as if your power supply is failingand/or your logic board. I think it's time to take it in and have it looked at. But before you do that, try running the Apple Hardware Test, on your install disc.

Mac Pro display remains black after start up.

My 2008 Mac Pro display remains black after start up. It is plugged in properly and the light comes on, but the screen stays black. It first started doing this about a week ago, but after a manual restart or two, it would start up properly with the display working. Today the display has remained black every time I've tried to start up. Any suggestions for troubleshooting would be greatly appreciated! Thanks!

Safe Mode uses a very simple way of talking to the screen -- it does not even load the screen driver, and it uses a very common low resolution.
If it does not work that way, it simply does not work. You need a replacement graphics card.

HT201263 Iphone4 screen stays black after configuration

Iphone4 failed to respond during normal usage. Therefore I turned off the Iphone4 and restarted the device. Unfortunately the screen of the Iphone stayed black after seeing the apple logo.
As the above didn't resolve the issue, I restarted the Iphone by holding the home and power button. The apple logo appeared again and than the screen stayed black. Although the i-phone is making sounds and you can switch between normal and silend mode.
Than I rebooted the I-phone by using Itunes, and reinstalled a backup, also the screen stayed black after the backup. Although in the beginning you can see the adapter and I tunes logo on the Iphone screen.
Than I rebooted by using Itunes and set up as a new device. I can see the following screen:
After swiping the screens turns black although when I touch the screen I can hear the phone is still working.
How can I resolve this issue?

Call of Duty puts a heavy processing load on several internal components that may be causing them to overheat. I would suggest that you download and install the Free and highly recommended "iStatPro" utility and post the temperature readings that it gives you, around the time that the time that the display goes blank, here in this Forum. (Play the game for quite a while and then check your temps in iStatPro.) That may give us the data we need to diagnose your problem.
You can download it for free here:

Laptop screen remains black (off) when I turn on the computer

Hello,
Today I came home and turned on my laptop as usual except this time the screen remained black. I can hear the fan running and then the usual windows chime at start up, but nothing to view. The HP logo at the back still lights up though. Just the actual screen remains completely black like it is off. I tried connecting it to my tv via HDMI and to an external monitor but there's no signal. I also tried doing a hard reset which I read about here but that did nothing. I feel as though it's just the monitor won't turn on but everything else might be fine.
