Screen stays black on start up

This is my second Toshiba laptop to do this to me. I just got this one in 2013. The last one was a no go on fixing it cuz it was cheaper to replace it. Tonight i come home and the same issue. The screen stays black. I can hear it running but have no lights except the white one in front showing its plugged in. Any help will be appreciated. Getting disappointed in this brand.

IMac starts with fan, screen stays black

When attempting to start my iMac G5 (Ambient Light Sensor), fans come on but screen stays black. A couple minutes later, the fans rev up and run very quickly and loudly. This started happening when:
1. One day the screen showed a green question mark with a message indicating that the computer needed to be restarted in a box
2. Green lines were all across the screen
3. I forced it to shut down by holding down the power button
4. When I attempted to start it back up the fans started but the screen stayed black
5. After a couple of minutes, the fans revved up
This has been happening ever since. One time the computer started to the desktop but everything was frozen. I have reset the PMU, checked the diagnostic LEDs, reset the PRAM-basically everything suggested. Can anyone help? Thanks!

Start-up problem with my Macbook - light stays on and screen stays black?!

Hi, sometimes when I start up my Macbook the switch-on light stays on and the screen stays black. Then I have to turn it off and when I restart it boots normally. What can this be? I resetted already the PRAM and the firmware is up to date. Perhaps someone understands german. Therefore I added my german post... Many thanks in advance!
Hi, hab ein seltsames Phänomen. Manchmal, vor allem nach ausgeschaltetem Zustand über Nacht, leuchtet nach dem Einschalten das Einschaltlicht auf und geht nicht wieder aus, wie normal wenn das Macbook startet, sondern bleibt an und der Bildschirm bleibt schwarz. Dann schalte ich das Macbook mit dem Ausschaltknof aus und warte ein paar Sekunden und schalte es dann wieder ein. Daraufhin startet es ganz normal. Woran könnte das liegen? Hab schonmal PRAM resettet und die Rechte auch repariert. Der Hardwaretest zeigt auch keine Probleme an. Kann man(n) noch irgendwie überprüfen, woran das liegen könnte oder hat das Problem auch schonmal jemand gehabt? Mein Macbook ist gradmal 2 Monate alt und hat das Problem erst seit kurzem. Könnte das vielleicht auch an einer Software liegen, die ich installiert habe. Kann sowas auch Auswirkungen auf den Bootvorgang haben? Bin Laie und würde gern wissen, ob sowas auch an der Pufferbatterie oder einer kalten Lötstelle liegen kann oder könnte das Macbook da dann gar nicht starten. Wäre für jeden Vorschlag dankbar... Vielen Dank schonmal im voraus!

Hi,
put me on the list as well. I was already in contact with ADC and it seems to me that they acknowledged it as a bug. I'm using a Mini-DVI-to-VGA adapter. And sporadically when unplugging it the internal display stays black or switches to the blue background and hangs there.
As I heard from friends who are using the Mini-DVI-to-DVI adapter in the same use case, this doesn't happen to them.

HT201177 When I turn my computer on, I can hear it starting up but the screen stays black. Anyone know how to fix this?

When I start up my compute, I can hear it starting up but the screen stays black. Has anyone else had this problem and found a fix?

If you press the caps lock key does it light up? If it does then this indicates that your system is booting but the display is either not recognized, is not displaying any video, or the display is displaying video but the backlight system is not lighting up. As long as you've tried turning up the brightness then there is not much you can do other than take it in for a diagnosis. If you have a very bright flashlight you can turn on the iMac and then shine the flashlight onto various areas of the iMac display to see if you can see any faint images on the display. If you do then this indicates that the display is displaying the image, but the backlight is not turning on for some reason. It doesn't change the outcome, but at least you can assist the technician who is troubleshooting your iMac.
Please let us know what you find out.

Satellite A200 screen stays black when trying to boot

Hello everyone,
My Toshiba Satellite A200 notebook is not working anymore, so everything started when I was playing a game, suddenly, the screen turned blue with some tiny text written on it. I had to hold the power button a few seconds to close it because nothing was happening on the computer. I then pressed the power button to open it. Everthing was going well, until the welcome screen. At this part, it was written "Welcome" but the Vista loading circle left of it wasn't turning.
After a few seconds, I decided to close the computer again, so I did hold the power button so the computer closed. Here is the problem : I tried to reopen it, but the screen stayed black. Nothing was happening. The power light was blue, but not any computer activity. So I let it like that a few minutes then closed it and tried again, but the same thing happened. I tried to disassemble it and noticed one of the two memory card wasn't fully in its slot. I fixed it, but it didn't fix the problem.
I also tried to plug another screen on it, but that one was also black. So I put back the screen on its computer and tried to boot my laptop and it worked. It was booting, but the first problem came back, the Welcome screen was frooze there. So yes I did close it again and then the same thing happened, the screen stayed black.
I don't think the problem is the screen because as I said sometime it goes to the welcome screen. Also I don't hear any welcome sound when the screen stays black as if the computer would simply not start up. And as I said earlier, I don't see any computer activity on the little light in front of the computer. And left of this one, I clearly see that the computer is ON because the power light is blue.
So this is my problem, next time the computer manages to start up I'll try to boot it on the SAFE MODE, but until then, I don't know what to do. Please, help me.
Thanks in advance,
MrRoy
EDIT :
After letting the computer turned off for about 30 minutes, I started it, and booted in safe mode. At this step, I securely closed my comptuer with the shut down button instead on holding the power button. Then I reopened my computer, and it booted and the problem was fixed. Now my notebook is openened and working.
So if this is happening to you :
1. Shut down you computer.
2. Wait for about 30 minutes.
3. Boot in safe mode
4. Shut it down using the shut down button istead off holding the power button.
That should work.

Finally, it doesn't work. I don't know why but my computer did start up after the 30 minutes, but now it's not working anymore. It just won't startup like I said later, with a black screen.
The computer did work for about half an hour. I mean, I managed to start it up but after executing a program, it just froze and I had to hold the power button to restart it. I did it about 3 or 4 times, then it simply did the black screen again. I think the problem is my processor, maybe it's damaged or something, could it be possible?
Because I see that the processor isn't working when I try to start it up.
So let's say it's damaged, would that be the symptoms of my computer?
And if it's the processor, the only way to fix it is to send it to a reparator or something, because I don't feel like it, I'd rather do it myself.
But right now, my computer is simply not booting, like I said in my previous post.
Thanks in advance,
MrRoy

IMac's screen stays black

Went to wake up my iMac, heard the computer running but screen stayed black. I've tried restarting and unplugging and re-starting with no change. Any other suggestions?

If you don't know what a RAM disk is then you're almost certainly not using it. This was a feature in OS 9 to use RAM as very quick disk storage space. It was not enabled by default. Unless you've created a RAM disk (on Apple Menu > Control Panel > Memory) and saved files to it, you're safe).
Take care only to reset the PMU once.
You should probably start a new thread so you get more attention to your issue.

When i try to wake my macbook after sleep the keypad lights up but the screen stays black. I have to switch off and restart. How do I fix this?

After my Macbook goes into sleep mode it sometimes won't wake. The keypad lights up but the screen stays black. This problem has only occured after updating to OSX 10.7.2.
All I can do is switch off and restart. Then any programs I have not 'quit' all open.

OK, I have a fix.
After spending about an hour online with Apple Care without success, I did a reinstall of the Lion OS. It fixed the problem. I was concerned that I would lose data or settings, but the reinstall was seemless and everything was the way it was before the reinstall except that the "black screen on wake" problem was fixed.
I started the reinstall before I went to bed and it was waiting for me the next morning.
Here is a link to the page on how to do the reinstall:

IMac from 2010: sometimes the screen stays black, only restoring from backup helps.

hello there dear community,
i have been a great fan of my imac and macbook eversince i first got them. but recently - probably since maverick - i am experiencing a series of problems with my 2010 27" imac. let me be more precise: eversince i got maverick, my imac keeps asking me to update every other day. usually i'm doing this or waiting for a couple of days. it's been exactly three times now that when my imac asked me to update and i postponed it that troubles occured. every single time i am not able to switch from sleep mode into the regular one. the screen stays black and the cursor is visible (and moveable). also i can clearly hear that the computer is on and working. the screen is black, but not in a mat kind of black but as if there was light behind it (i.e. the screen is switched on).
when this happened first, i called the apple support and we tried a lot of things and spoke for more than an hour. the only solution that worked out was pulling the plug, waiting, putting it back, restart the computer with cmd+r pressed and then restore the system from a backup that i had saved on an external drive. this of course takes time, usually up to four hours, but yes - it works. and i am very glad that there is a solution at all to this mess - but it's very idle.
now my question: there must be another way? or even better: how do i avoid that my imac falls to a sleep from which it can't really awake?
thank you for your patience and thank you for your help!
cheers

IPAD Screen Stays Black even after reset.

Hello
I have a case similar to the one posted by darKnghtV on Jun 24, 2012 10:12 AM related to screen stays Black.
after I have stopped using the device for 3 days, I came back and the screen came back on. I reset the device to factory setting and it has been working fine for two days.
how can I confirm if the issue is a hardware or software?
if the device is defective, how can I exhaust the screen to show the issue again so I can take it to the service center?
Regards

I have done this few times.
however I had to use screen shot, view the image from my PC to have the unit reset to factory setting. even after that screen wouldn’t start.
when I took it in the car and it was a hot day, I reach the work shop and the unit was really worm, screen came back on and it did not go black again for the past three days.
what is puzzling me, was it fixed after the reset and it is a software issue, or is it a hardware ?

Macbook screen stays black

I opened my Macbook today and it made the usual sound, but the screen stays black. What can I do? Thanks in advance.

Hi iNonna and welcome to Apple Discussions!
So you got the usual startup chime but no video during or after startup, is that right?
I would start out by [resetting the System Management Controller|http://support.apple.com/kb/HT3964]. If there is no video after that, it sounds like you need to take the MacBook in for a repair. You don't say where you are but you can contact Apple for a repair at one of the phone numbers on [this page|http://www.apple.com/support/contact/phone_contacts.html] or carry it in to an Apple retail store. Be sure to [make an appointment|http://www.apple.com/retail/storelist> first or you may spend a long time waiting to talk to a Mac Genius.
Best of luck.

My macbook pro will turn on but screen stays black.

My macbook pro will turn on but screen stays black. There is no sound on start up and keys dont light up. I have done all the resets:
I disconnected the computer from the power cord, and from all other cables.
I held down the power button for several seconds to turn off the computer.
I let it sit 5 minutes.
I restarted the laptop while holding down the Shift key and nothing happened.

I need lots of help!!! any ideas? Its a MacBook Pro 15” or 17.5” about 5 years old. Its about 2 updates behind (OS: Snow Leopard)

Zane W is giving you good advice. Take it to an Apple store genius bar and have them examine it for free. You then will know what the issues are and then can make informed decisions.
Ciao.

I have a HP Touchsmart 300-1020 that powers up but the screen stays black. help!

I've been experiencing problems intermittently after shutting my TouchSmart 300 PC down. For the past few days when trying to turn it on ; the screen stayed black! I could hear the fan start rapid then slow down, I can see the green internal light blinking inside and lights on the outside of the computer but still nothing on the screen! I've tried plugging it into different outlets around the house was successful with one, but then, came the error message;
Page fault in nonpaged area. Today I tried to turn it on and I got the same thing described above. The computer's operating system is Windows 7 64-bit, purchased Feb. of last year and is refurbished.

Hi
You have a couple of options as I see it please run the Hard drive and Memory test check if both off then passes if any fails then you need to replace the part. If test passes you could try The F11 option to do system restore Or to do a recovery on the unit before doing recovery kindly back up data as it will be lost web link given below this will help you to let you know how to do the steps.

Hope this helps:
As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a

How do i fix my iod touch... screen stays black

how do i fix my iod touch..... the screen stays black with the apple logo then cuts off again after like 5 minutes..... someone please help me ?

Please tell me it's not jailbroken. If it is, all bets are off. It is not...
First, 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. Connect via cable to the computer that you use for sync. 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. Again, say "yes."
Finally, if the Restore doesn't work, let the battery drain completely. Then recharge for at least an hour and Restore again.
