I have an iphone 4s that is having display issues. If I turn the phone on, it vibrates to acknowledge it successfully turned on but the screen stays solid black. I can plug the phone into my computer and itunes will recognize the phone as well.

I have an iphone 4s that is having display issues. If I turn the phone on, it vibrates to acknowledge it successfully turned on but the screen stays solid black. I can plug the phone into my computer and itunes will recognize the phone as well. However, itunes can not do anything with the phone because the phone is locked and I can not unlock the phone because the screen is black.
>CURVEBALL!!!<
The screen does work though! Through trial and error along side a little troubleshooting, I was able to figure out that the screen will cut on after the phone dies completely. The phone has to die completely with no battery power left. Then if I plug the phone into a charge and wait a while for it to charge, the phone will turn on like nothing was ever even wrong with it. I charge the phone up to like 30% and turn it off then bam the phone turns on but the screen is solid black again.
I am currently in the process of waiting for the phone to die and when I turn the phone back on I am going to completely remove the auto-lock and lock code off of the phone for the time being.
Any other suggestions? Please help!

Sounds like the device was dropped at some point and damaged as a result.
Take it to Apple for evaluation and a replacement.

I have to believe this has something to do with iOS 7 issues. I have taken my screen blacked out 5s twice to the Genius Bar and the found a bunch of system apps had crashed. So if this is the case, is iOS7 the problem?

Outlook mail being received but blank screen when I open the app

Outlook mail being received but blank screen when I open the app

This seems to be going on around here for a couple of days. I have seen several discussions about the mail app opening to a bank screen with different variations and issues after the blank screen appears. I wish I could say that my suggestion is the definitive fix, but I can't. Give it a try anyway and see what happens.
Close the mail app completely and reset your iPad. Not data will be lost.
In order to close the mail app, you have to drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the mail app then swipe "up" on the app preview thumbnail to close it.
Next, reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Equium A300D-16C turns on but the screen shows nothing/stays black

Hi there, I have a Toshiba Equium A300D-16C laptop.
It was fine until now...
When I press the power button, my laptop turns on but the screen remains black / off.
HDD indicator doesn't flash or anything ... ( in case this helps )
I've also tried to remove the battery, hold the power button for 30s and plug the power cord back in... Same thing laptop turns on but screen is black.
I tried to connect my laptop to my PC's monitor using HDMI cable but no success... Laptop turned on but my pc's monitor was showing nothing.
I haven't changed anything inside my laptop or unscrewed it.
PS:
I quite often kept my laptop on the bed/pillow so it may have something to do with overheating or something.
How did I get to this point:
Yesterday my laptop was fine, there was nothing wrong with it... I switched it off at night but when I tried to switch it back on this morning that's where I faced this problem.
Any help would be appreciated.
Many thanks,
Rejanu.

Hello
> I tried to connect my laptop to my PC's monitor using HDMI cable but no success... Laptop turned on but my pc's monitor was showing nothing.
Its very good that you have this test with an external monitor because so you could make sure its not related to internal monitor and its working properly.
Well, you have tried a lot so my personal opinion is its a serious hardware malfunction It could be related to mainboard or CPU in my opinion
I think such hardware diagnostic can only be done from an authorized service provider. I think you should contact the guys. They can help you to get rid of this problem :)

Make a PRAM reset > http://support.apple.com/kb/HT1379 Also, reset the SMC > http://support.apple.com/kb/HT3964
If they don't work, that may be a display or GPU issue. Take your MacBook Pro to an Apple Store or reseller. If you want to know which is the part, connect an external display

Apple won't replace an iPhone under warranty if the iPhone has been opened/tinkered with by you or by a 3rd party, but they may under Apple's out of warranty or not covered under the warranty "repair" price.
There is only one way to find out for certain.

HT1366 My MacBook OS X version 10.6.8 is not going to sleep, keeps loading, then when turned on a blank screen appears, I shut it and the main menu comes up and then it takes awhile for the cursor to operate. Thanks

My MacBook wouldn't go to sleep, it keeps loading, so I have to turn it off. When I turn it on a blank screen comes on, I shut the lid and open it and the main menu screen comes up but the cursor won't work for awhile. Then, eventually, the cursor will work and everything is fine. Hmmm?
