IPhone screen keeps going blank

My iPhone screen keeps going blank. If I reset the phone, it comes back on but after a while, it goes blank again. I don't know what to do?

Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.

My screen keeps going blank still have sound

my screen keeps going blank but still have sound

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup. See:
iOS: Back up and restore your iOS device with iCloud or iTunes
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

My iPad keeps locking itself every few seconds, any ideas how to fix it... Drives me mad having to put my pass code in all the time and the screen keeps going blank :( HELP!

My iPad keeps locking itself every few seconds, any ideas how to fix it... Drives me crazy as the screen keeps going blank and I have to constantly put in my pass code every few seconds. Can someone help me out please. The pass code lock is set at 10 minutes but it's happening every few seconds :(

I've run into the issue and it seems to be related to an app not fully supporting the iOS you're on, the reboot doesn't usually solve it.
I've solved it in the following manner(s):
1) Backup the device to iCloud, then erase the iPad (Content and Network Settings).
2) Setup the iPad and choose to restore from iTunes/iCloud Backup (wherever you backed it up)
3) Perform any software updates
I have not tried simply performing the software updates (which may fix it, but if it doesn't you won't be able to perform the above steps).
Enjoy.

My Mac book air screen keeps going blank

Recently my Mac book started giving me a blank screen when I turn it on. The desktop will occasionally flash on but as soon as I hit the mousepad it goes blank again. Any ideas?

Hi ...
Try here > Troubleshooting: My computer won't turn on

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

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:

T41 screen suddenly goes blank - possible overheating?

Having an intermittant problem with my T41, and wondering if anyone has any idea as to the cause.
Most of the time, I use it in a docking station. Sometimes, after I've been using it for a while, the screen suddenly goes blank. There's still hard drive activity, as the light keeps on flashing, but the screen stays blank no matter what I do. The only way out is to do a hard reboot via the power button and, when I switch it back on again, the screen comes back, but usually some of the desktop icons have changed places. One time, the screen resolution had also been reduced to 800x600, and I had to reset it back to 1024x768.
I have noticed recently that, when it does this little screen shutdown trick, the fan doesn't seem to be operating and, if I remove the computer from the docking station, it does seem a bit warm underneath. Then, when I reboot the computer, the fan kicks in right away and seems to be pushing a lot of heat out of the vent in the side.
So does anyone know if this is an overheating issue caused by the fan not kicking in when it should, or could there be another cause? One thing that has me confused is that, according to the Windows fault reporting system, it says its a video driver fault and I should update the driver. So can anyone tell me just what the problem really is?
Edit:
I've been able to find one of the manuals as a PDF, and it seems like the computer is unexpectedly hibernating due to the CPU overheating. Unfortunately, that's all it says, and doesn't give any advice as to how to fix the problem. Does that sound like a correct diagnosis?
Solved!
Go to Solution.

Don't know why this topic has been marked as "solved" when it's still an ongoing problem - I certainly didn't mark it as such!
Installed the program you suggested, and ran a few tests. From those, it looks like the issue could be the CPU, not the GPU, that's been overheating and causing the hibernation. With the computer just idling, the CPU temperature reports about 35-38 degrees C, while the GPU sits around the 40-44 degrees C mark. Playing a HD flash video, the GPU temperature went up to around 50 degrees C, while the CPU went up to 69 degrees C. At that point, the fan hadn't kicked in, so I switched from Smart to Manual mode, at which point it started in Mode 7 and brought the CPU temperature back down.
I then ran the test again a few more times with different videos and, with Smart mode selected again, the fan did kick in automatically at around 66 degrees C on the CPU temperature, but only in Mode 1. This seem to just stabilise the temperature, not bring it down, and I had to go to Manual mode to get a higher fan speed.
Before I installed the fan control program, I don't think the fan was kicking in at all, as there was no sign of air coming out of the vent. The only time the fan did kick in was after the reboots, and then only for a minute or so. The program seems to show that both the CPU temperature sensor and the fan are working OK, but it appears that they aren't talking to each other properly. Any ideas why this could be?

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?

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

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.

Wht does my computer screen keeps going dark?

Why does my computer screen keep going dark?

Good. This means that, in your existing account, a setting is bad or .plist file is corrupt. As identifying the rascal may take time, my suggestion is to move data to the new account, must be with administrative privileges. As the contents of each account is unavailable to the other, there are two methods:
- if you have a backup on an external disk, as you should (if not, consider this seriously, do not count on good behavior of hard disks), make a last backup on the existing account, and restore in the other account; when ready, delete the old (buggy) account
- if not, save your settings unto a flash drive; this is a limited backup just to avoid putting back settings for Mail etc. I am satisfied with iBackup (grapefruit.ch), but there are other backup utilitites, Time Machine, for example; TM does not allow limited backup, it works if you have a large external disk. If backup disk is not available, move files to shared folder, which is visibile from both accounts, and from there to the new account.
May seem difficult, in fact it is not. You must just move data from one account to another. Now, take care to new apps you install or new functions you activate. When you notice something strange, that may be the cause of this behavior.

Lost Registration is something that I used to see now and then, but seem
quite uncommon now on current code, though I dont recall any specific
bug/fix.
Below are a couple of scripts that can be called from login scripts to
address a couple different registration issues.
