Ipod touch screen went black and then started flashing. Then the turn off slide comes up.

Ipod touch screen went black and then started flashing. Then the turn off slide comes up. Restored multiple times and didn't work. Ipod works with Itunes fine (can put music and podcasts on the ipod), but can't take songs off of the ipod. Using windows xp and everything is up to date. Any ideas of how to fix it?

I didn't know that it was posted three times. My computer didn't say that it posted anything.
My ipod still syncs to itunes and I can put podcasts and music on my ipod, but I can't delete songs after I put them on the ipod. When I try to delete songs I try to delete it from the main music list on the ipod. It's also doing all the other stuff that I posted before. The screen will go black and then the power off slider thing shows up for a few seconds, then it'll show the unlock slider bar. Then goes black again. It will also do that when I have the ipod unocked and changing songs or playing a game. I've restored it to the factory default/new ipod and it still does the same thing. I've uninstalled and reinstalled itunes and then restored it again to the factory default and it's still doing the same exact thing. I checked and my computer is up to date.

XPS One 2720, screen gone black?

Hi,
I got Dell all in one XPS 2720 last July, 2014. It has been working fine so far only once the touch screen lost and regained once I sort it out the issue with USB. I have not connect this computer to internet for the last 3 months. Today I connected it to internet after one hour the computer screen gone black not responding to any touch function, It also does not respond to any keyboard touch. I tried to read the "me and my dell" instruction, nothing seems work. anybody has some advise.

Disconnect the power cord from the rear of the XPS One 2720. Press and hold in the power button for 15 seconds. Reconnect the power cord. Press the power button.
Are there any beep codes?
Look at the power button:
Solid amber = The computer has detected an error during power on self-test
Breathing amber = The computer is in sleep/standby state or There is a possibility of system facing an issue
Solid white = The computer is ON
Off = The computer is off or in hibernate state

HT2188 iphone 4 screen gone black

I was using an app when suddenly the screen went black, and after that nothing was responding... i pugged in for charging, but it wasnt responsive... later connected on to the Itunes, but again nothing was responsive... i even tried the wake/sleep and home button for 10-15 seconds, but still its not responsive... Can anybody suggest me what to do next?

If you take apart your iPhone to do anything, it will void your warranty. You can pay an out-of-warranty fee for damage that's $149 if you open the phone.
Try a hardware reset while connected to the charger.
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 15 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.

Screen goes black immediately after booting up

Screen goes black immediately after booting up....except when just using the battery. If I plug in the cord, the screen goes immediately black, yet it is clear the computer is still working. There have been no hardware changes. Any advice would be appreciated. Thanks.

junefromoakland,
are you using your MacBook Pro’s original AC adapter when the screen immediately goes black?

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.

Screen goes black when making phone calls

Hi, I have started to use a new Xperia Z2 a short while ago. As soon as I am tapping the screen to call a phone number the screen goes black; I can hear the phone calling but can't see anything (not being able to turn on loudspeaker etc.). The sound works, and screen can be brought back to life when the call is finished. Same thing when I call with my Skype app - really annoying as the video mode in Skype doesn't function. When the call is finished from the other side, I can get the screen to light up again. What can I do to solve ths problem?

Hi.
I've got very simillar problem with Xperia Z2 screen.
Not always, but very often when I want to end the conversation and take the phone away from my head, screen remains black.
Only power button can help, when I click it, screen pops up and then I can click "END CONVERSATION"
It's really annoying. What can I do, to make it work ?

- I don't have any protection on the screen

My ipone4 screen is black cannot answer when calls come in

The screen went black/blank, I cannot answer it but it allows calls to come in - any suggestions?

Hello Pamd21562,
Thanks for using Apple Support Communities.
Since your iPhone is still on and functioning aside from its screen being black, I recommend you follow the troubleshooting below.
If you see a solid color screen (black, white or blue)
Plug in your device to a power source. If you see the low-battery screen when you plug in, let your device charge for at least 10 minutes (20 minutes for iPad) before using it.
Reset your device while it's plugged in.
If resetting doesn’t fix the issue, restore your device.
If you still see the issue after you restore, contact Apple Support.
Get help with the screen on your iPhone, iPad, or iPod touch - Apple Support
Take care,
Alex H.

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 ?

Iphone: Screen gone black, Won't turn off, Restore has failed, 1.1.3

Hi,
I am having a problem with my iphone after upgrading to 1.1.3. The screen has gone black with a white spinning wheel(resembles a flower sort of).The wheel however is not spinning. I can see the top bar with the time, battery, and signal strength. The phone however will not turn off and restore yields an "Unknown Error (-19). Has anyone else had this problem after updating? Anyone have a fix for it or is this a job for the genius bar?
Thanks for your replies.

Imac Screen gone black

Helpppp! My Imac screen went black or rather does not come up after the start up sound. I should say this was during a thunderstorm and I think I heard the spark of electricity around the system and shortly after the contents on screen became distorted. I put off the system and the display no longer comes on. Please come to my aid.

Thanks for your help BDAqua but I'm afraid the situation remains the same even after trying out your suggestion. I have taken a photo of the screen with my phone and this is photo is the best the screen can do. I hope it helps in diagnosing the problem

N97 screen gone black ?? please help

the screen on my n97 had coloured lines going through it this kept happening for a few days and then the screen went black i can still get calls etc and the touch screen still works? if i slide the phone open or close the screen sometimes goes different colours!!
can any one tell me whats wrong or how i can fix this please

From what you tell, I'm 99% sure that your device suffers from a hardware failure/malfunction. AS we cannot help you with such issues here, you will have to visit a Nokia care point to get it repaired.
Similar issues have been reported many times regarding similar devices. Most of them seems to be with the 5800 and the other 5000 candy bar touch screen phones.
Good luck!

How to replace the inverter cable? screen gone black in MacBook

Hi
There is no apple service provider in my location. Can I replace the inverter cable without having to take the MacBook to an apple store? is it easy to do? and can I use any inverter cable? or does it have to be especially designed for Macbook?
I have a black Macbook. The screen used to go black sporadically, and now it has totally gone black, and I couldn't get it to work again.
Any advice????
Thank you

Your answer is most helpful and sincerely appreciated, Level 6
Looks like the cable in question being identical throughout "The Black Period".
Looking at it right now it seems easier to patch than waiting for a replacement. Will report back if it wasn't.
Mine is a 2.16 GHz Intel Core 2 Duo 13-inch Mid 2007, heavily hacked.

My ipad was in the process of updating (ios7) while at the same time syncing with my laptop. suddenly the screen turned black and after few seconds the new itune icon appeared on the screen. the same icon appears even after i reset it.
