Screen keeps going black and I can't get it to light back up

I just purchased a "pinkberry" and am getting very frustrated with it. It keeps going black and no matter what buttons I push I cannot get it to light back up. I got it yesterday and charged it for about 12 hours so I know it's not that the battery is low.

seems like a hardware problem. Return the device to where you bought it and claim a new one.

My iphone 5 has just had an update for candy crush and ever since i opened it the screen has been black and I can't get it to do anything what can I do?

- Quit the App by opening multi-tasking bar, and swiping the App upward to make it disappear. (For iOS 6, holding down the icon for the App for about 3-5 seconds, and then tap the red circle with the white minus sign.) Relaunch the App and try again.
- Restart the device. http://support.apple.com/kb/ht1430
- Reset the device. (Same article as above.)
- Reset All Settings (Settings > General > Reset > Reset All Settings)
- Delete the App, then reinstall it.
Test the issue after each step. Make sure to quit the app as described before each followup step.

MacBook screen keeps going black and won't reboot

I have a 15" MacBook Pro, Early 2011 running 10.9.2. This rather alarming problem started recently, about two weeks ago:
At random, my screen will "glitch out" and go black. This usually happens when performing some innocuous action like moving a window or opening a random app.
When in this state, the MacBook will not wake up so I have to do a hard reboot. Then the system will not make it back to the Finder. It will get to a solid gray screen, I can hear the fan ramp up and then it will shut itself down again.
The only way to reboot is to go into single user mode (command-S) and then run "/sbin/fsck -y" twice because the first run modifies my startup disk for some unreported reason. Then my MacBook will run fine for a couple hours before I have to repeat the process all over again.
I've run Apple's Hardware Test and everything came up fine. I did some research and found this old article, which describes a similar bug in the MacBook model prior to mine (late 2010), which suggests some kind of known graphics card hardware bug:
http://www.cnet.com/news/apple-acknowledges-2010-macbook-pro-black-screen-bug/
Any solutions out there, beyond taking it to an Apple Store?
EDIT: I subsequently found this discussion, which describes the same defect:
https://discussions.apple.com/message/25002119#25002119

I've found a solution — or rather a patch. I downloaded gfxCardStatus and set it as a Startup Item. It adds an icon and menu to Mac OS X's menu bar, and from there you can tell the system to use the "Integrated Only" graphics hardware instead of "Dynamic Switching."
This apparently prevents the system from using the "Discrete Only" graphics hardware, which in my case was causing the crashes.
This patch allows all graphics-intensive apps to run on my Mac, including iPhoto, Photoshop and SketchUp.
Apple, when are you going to address this problem? Your hardware test apps failed to find any hardware problems.

IPhone screen keeps going black and buttons are unresponsive

Hey everyone, I left my iPhone 5 on charging and woke up to find the screen black, as if it's been turned off. None of the buttons work and neither does hooking it up to the computer. I held the power and home button together to reset it and turn it back on. Luckily it worked, but after an hour or two the screen went black again. This has happened four or so times since yesterday and is getting quite annoying. Does anyone know what is the cause of this problem or how it can be fixed?
Thanks

To make sure that this is not software related, set it back to factory settings without using any backup:
Use iTunes to restore your iOS device to factory settings - Apple Support
If this does not work, contact Apple Support to get it serviced:

Help! My MacBook Pro screen keeps going black and I have to reboot. I have sent the error report numerous times to Apple to no avail (See below). I also took it into the Mac store and they reinstalled Lion to no avail.

Looks like an issue with the GPU or with VRAM. You do have a third-party extension loaded, so you might try working in Safe Mode to see if the panics cease. If they do then uninstall the software for VaraAudio to determine if its driver is the cause. Also disconnect any third-party peripherals.

My iPhone 4 was charged and working, then it went black and I can't get it to turn back on.

I have tried plugging in to computer and wall charger. Nothing is working!

Reset, Hold both Home and Power buttons until the iPhone begins to restart itself, usually takes 10 seconds.

I dropped my ipod in coke. The screen keeps going black. Is there anything i can do?

Your iPod is toast. No amount of dry rice is gonna help.
"Coke" and other carbonated drinks are acidic (carbonic acid), not to mention loaded with sugars and other nastiness.
The acid will "eat" metals, like the lead and tin in solder, most liquids will wreak havoc with the LCD display, and since "Coke" and its cousins are acidic, they are also good electrolytes and will conduct electricity.
You can try filing a claim against your home owner's insurace, but barring that, you're out of luck.

I am trying to hook my macbook pro to a projector, which has a VGA cable. I bought a VGA to HDMI adapter, but whenever I hook it up, the screen on my macbook just goes black and I can't make it do anything else or even show up on the projector.

My laptop is still on; it just has a black screen that I can't get rid of without shutting down the computer by holding the power button.

Hey there lynmrigg,
It sounds like have an HDMI to VGA adapter connecting your MacBook Pro and your projector but the screen on your computer goes black and no image appears on the projector. I would use the troubleshooting in the following article to help resolve or isolate the issue here, named:
Apple computers: Troubleshooting issues with video on internal or external displays
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.
Thank you for using Apple Support Communities.
Take care,
Sterling

Hello @DesCherryBomb,
I understand that you are having issues with your HP 2310m monitor going blank and/or flickering. I am providing you with some steps you can try below:
Step 1. Unplug the power cord from the back of the monitor and the wall
Step 2. Hold the power button down for at least one minute
Step 3. Plug the power cord back into the monitor and then into the wall outlet (not a power bar or surge protector)
Step 4. Press the Menu button on the monitor
Step 5. Navigate to the Factory Reset option and select it
If the above steps did not resolve your issue you can try the monitor on a computer or other device to see if the issue persists. Please call our technical support at 800-474-6836. If you live outside the US/Canada Region, please click the link below to get the support number for your region. http://www8.hp.com/us/en/contact-hp/ww-phone-assist.html

Lenovo z50 screen keeps going black

I've had it for around 6 months with no problems, then in the last 48 hours, the screen keeps going black when I'm using it. It happens every 20-30 minutes. If I close the laptop lid and open it again, it works fine until the problem comes up again. I've tried downloading updates and placing a fan by it, but it keeps happening. Any ideas?

My iphone 3gs keeps going black and to a "thinking" icon

my iphone 3gs keeps going black and to a "thinking" icon and will do this for a long time and won't stop till I do a forced shut down. It's all sporatic as to when it does this. Plus it's adding pictures to contacts that don't normally have pictures and taking them away from ones who do have them. Does anyone have any suggestions? I have iOS 5.1.1 on it still b/c my iTunes won't download the newest verision of the iOS (yes I have the most recent iTunes on my laptop, yes I've tried multiple different times to download too) but I've heard others say not to put the newest iOS on the 3gs b/c it locks them up.

Try doing a reset on your iPhone,
Reset your iPhone by pressing the 'Sleep' and 'Home' button at the same time for about 15 seconds or so. Your iPhone will then go through a reset / reboot procedure and will be ready for use within about a minute.
Don't worry about doing this as you will not lose data or settings.
Good luck and do report back.

Is your battery out of juice, have you tried charging it? If the battery is flat dead it may take a few minutes after plugging it in before the screen will show anything.

My iphone 4 keeps going black and the camara light wont go of

I dont know what happened, i left my phone downstairs came back down to get it and the screen keeps flickering then going black and the camara light wont go of . Can anyone help as i my phone is everything.

Just reset your phone:
Press the Sleep/Wake button & Home button at the same time, keep pressing until you see the Apple logo, then release.
This should let you use the phone normally, no restore needed.

Why does my Ipad keep going black and then back to the apple logo. It eventually goes to the start page but then blacks out again. I have already rebooted several times with no luck!!

Why does my Ipad 2 keep going black ahd back to the apple logo. It eventually goes to the home screen and allows me to try something else but after about 30 seconds it happens again. I have already rebooted several times?

Make Sure iOS is updated to the latest version
Reboot the device by pressing and holding down the home and sleep/wake buttons (power) at the same time until the apple logo appears on the screen, then let go.
If that doesn't work then reset the device by going to settings/general/reset/reset all settings

Screen keeps going black and I can't get it to light back up
