hello. my phone screen goes blank and after a minute or so goes back to home screen. why? any help please?

Howdy mbaeguasu,
It sounds like your iPhone may be restarting unexpectedly while you’re using it. Take a look at the article linked below and, if you haven't already, try installing the latest version of iOS on your device.
If your iOS device restarts, displays the Apple logo, or powers off while you're using it - Apple Support
So long,
-Jason

Just upgraded to latest iOS and my iPad does not come back up. It displays a line to an iTunes logo and then goes off and after some minutes comes back on. I cannot reset it or anything else.

Just upgraded to latest iOS and my iPad does not come back up - the following appeared as the first thing after turning back on. It displays a line from the power/USB connector to an iTunes logo and then goes off and after some minutes comes back on. I cannot reset it or anything else. It is completely non-functional.

When I am on a phone call and I double click the button to go to my home screen, then open another application (usually my calendar program, Calengoo), my screen goes blank and I am not able to return to either the app, the phone, or the home screen.

When I am on a phone call and I double click the button to go to my home screen, then open another application (usually my calendar program, Calengoo), my screen goes blank and I am not able to return to either the app, the phone, or the home screen. If I am speaking to a person, if they hang up then I am back to the phone application. If I'm leaving a message, I am unable to return to the phone screen to end the call, and have to wait until the other phone hangs up. I'm also unable to switch back and forth to look at my calendar if I'm calling someone about scheduling. This has only started happening since the most recent iOs update. I run into situations similar to this about once per day during the work week, as I use my phone is this manner quite often. While not life altering it is quite frustrating. Can anyone here help me figure out a way to avoid this? If it helps, I have noticed a general downgrade in overall performance starting two system updates ago (apps opening more slowly, closing unexpectedly more often, etc.). I have an iPhone 3GS with the latest OS update.
Thank you for any help or suggestions,
Chris

I could be corrupted backup.
You can check the notification settings for message.
Settings>Notification Center>Messages>Alert Style
It should be on Banners or Alerts.
Settings>Messages> Turn on Imessage and send as SMS and below that "Blocked" to check if you have any numbers block might be blocking the message.
You can also do a hard reset by holding power and home till it restarts and release after seeing the apple logo.
Still doesn't work? Settings>General>Reset>Reset all settings

Standard troubleshooting...
Try a reset by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider if, it comes up. Takes about 5-15 secs of button holding and you won't lose any data or settings.
Remove all apps from Recently Used list...
- From any Home Screen, double tap the home button to bring up the Recents List
- Tap and hold any icon in this list until they wiggle
- Press the red (-) to delete all apps from this list.
- Press the home button twice when done.
If still a problem restore with your backup.
If still a problem restore as new, i.e. without your backup. See how it runs with nothing synced to it.
If still a problem, it's likely a hardware issue.

My iphone 5 screen goes blank and i am not able to do anything

My iphone 5 screen goes blank and i am not able to do anything. It happens in rainy weather and it comes back to normal after 3-4 hrs.

If you get your phone wet you risk permanent damage. Do not use your phone in the rain.

When i select the "Full Screen" option in video streams (like youtube, veoh, anything like that) i can do that one(1) time second(2nd) time the screen goes blank and can only exit it with the escape(Esc) button and then i have to restart firefox and again i have my one "Full-screen Ticket"

I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6.

Hi Mofimac,
Thanks for visiting Apple Support Communities.
If your Mac is only starting up to a blank gray or white screen after updating OS X, you can find some useful troubleshooting steps in this article:
Mac OS X: Gray screen appears during startup
I recommend going through these first three sections first:
Disconnect, test peripheral devices and network cables
Perform a Safe Boot
Reset the NVRAM / PRAM
Best Regards,

My computer screen keeps going blank and then going back to the box where I put my password in to start my comp. Why is this happening?

My computer (Macbook) was working fine this am. I left it for an hour and then came back and the screen was black (always does that as the screensaver hardly ever works). I moved the mouse to wake it up and everything was normal. I went to adjust the volume and the screen went blank and the main page with the box where I put my password in when I first start my comp appeared. I put my password in and everything was normal again. I opened a window in Safari and before it loaded completely the same thing happened, the screen went blank and went back to the password box. Does anyone know why this is happening? I don't have an external hard drive or any blank flash drives so I can't back anything up right now and am afraid I'm going to lose everything. Thank you

Sounds like hardware failure, called boot loop. Call Apple and or go on apple.com and make Genius Bar appointment to have your iphone reviewed by a Tech. Provided you iphone shows no physical or liquid damage they will take care of you, or if you have Apple Care Plus

Yes, your battery is likely toast and in need of replacement. Not much else for troubleshooting here. Sorry.

Right after starting up display goes blank and shuts down?

Right after starting up display goes blank and shuts down?
Any ideas I can't get it started. Thought I would ask for help before making a genius appt.

Thanks that was very helpful info. I was able to boot into the recovery disk partition and run some basic HD tests and it found no issues. Then I booted into the hardware test and it found no issues. After these tests it still failed to boot into Mavericks. I'm guessing its a software issue and I can not find the original computer disk. I have a time machine backup from 2 months ago and I could use the disk utility on the recovery sector to launch it but I want to wait and see if I can boot from a software DVD first. If I can repair the current OS that is my best option.
Thanks.

Apart from the lock button problem in iphone 5 the display brightness suddenly goes blank and becomes normal after locking and unlocking the iphone. The Apple service centre in India is denying to service the iphone as it was purchase in USA even thoug it

Apart from the lock button problem in iphone 5 the display brightness suddenly goes blank and becomes normal after locking and unlocking the iphone. The Apple service centre in India is denying to service the iphone as it was purchase in USA even though the iphone is in warranty.

iPhones do not have an international warranty. Warranty is valid only for the country of purchase. This is most likely because different countries require different iPhone models. Not reasonable to expect all countries to maintain stock for all models.

I can't access my mail,contact,calendars settings on my iPhone after update . i press the icon in setting and it just goes back to home screen.
