iPhone 6 s screen turns off then gets normal back in 10-15 minutes.

Hello everyone. I bought my iPhone 6 s 64 GB gray space to the end of December 2015. It came with Samsung A9 processor. For the last 3 months, it began to close its screen down randomly at least 1 time in 2 days. I think it has something to with the LCD backlight because the touch screen works on completely black screen. I can still receive calls by remembering where to touch. Then on an average of 10 minutes, it returns to normal. Is anyone else having this problem? Or suggestions? Thanks in advance.

(Incidentally opening and closing or restarting with power and button "home" at the same time does not.) Whatever you do, screen becomes normal when he wants. I tried hard reset, formatting and relief, but the problem is still there.)

Note: probably a coincidence, but it never happened before iOS 9.3

  • U2715H - Windows automatically resized when the screen turns off then turn it back on

    • Windows 8.1 Pro
    • 1 single monitor connected to the PC

    • through CDM of the monitor to the RFP the ti EVGA 750 SC (cable Dell)
    • all drivers updated on 28/12/15

    I just bought this monitor and I noticed this strange behavior. Whenever I have turn off the monitor (or it will turn off by itself), if I didn't have a maximized window, all windows (regardless of size) gets automatically resized to fit in the left upper quadrant when the screen turns back on again.  If I had something full screen, this behavior does not occur.

    I find this very annoying. This behavior happened with my previous monitor, which was only 1080 x 1200.

    I was unable to find any setting for the U2715H disable this "feature". This isn't because EasyArrange from Dell. I do not use this feature. And this always happens with Display Manager not installed.

    Is it just a 'feature' of Dell U2715H? Is responsible for Windows? Help, please.

    TIA

    There was no pilot or changes to the hardware of my first post.  BTW, my monitor is a Rev A02.

    A few days after my previous message, another question emerged.  Monitor flash intermittently ON / OFF every few seconds.  I unplugged/replugged the cable CDM - DP and that seems to fix things... until the next day.  This time, I nothing could fix the random rotation power SWITCH of the monitor.  Desperate, I decided to plug an old HDMI cable, I had to hang out.  Flashing problem has been resolved.  Not only this, using HDMI solved my original problem of auto resizing windows.

    The solution to my original problem: use an HDMI cable.  I went to the Dell CDM - DP cable and the problem has been resolved; no more windows resize automatically when the monitor turns off in sleep/towers.  I always get the native resolution at 60 Hz and there is no noticeable disadvantages to the use of the HDMI versus DP interface.  I've been using the HDMI cable for about a week and there is no other issue.

    Just for additional verification, I bought an Accell UltraAV DP - DP 1.2 cable (B142C-007 b-2), one of the few officially approved by VESA (see link below).  Using this cable does NOT my automatic window resizing problem original.  I do not use it long enough to see if they would prevent the random flashing question.

    I still don't know the exact cause of my original question.  I guess it's a driver problem with DisplayPort standard.  But if you do not need DP 1.2 functionality, I suggest that you just use your GPU HDMI output (if she has a).

  • Satellite 1800 - 752S - the screen turns off

    Hello world.
    I have a satellite 1800 - 752S.
    Since an ew months ithas a weird problem: the screen turns off. If I press and release the button the lid on what it is, but after that turns off again quickly. OT goes off sometimes immediately, sometimes after a few minutes, or even hours. Sometimes it provides be when I run out of battery and bothers me on AC, sometimes against. It works fine, after I turn sleep or hibernation several times, and after a reboot, it bothers me. I've updated his BIOS for the lates on this site, which would not help. I guess it's a hardware problem, because it's the same problem under Linux, and I tried to install different versions of drivers and windows (not only the one of the recovery CD). Anyone have the same problem before. Any help will be appreciated.
    Thank you very much
    Roman

    Hello

    I think you're right, it's a hardware problem. But to be sure, try connecting an external monitor. If it works without problem while laptops, screen turns off, then it must be a hardware failure.

    I guess it's a problem with the FL inverter. You have to give your machine a service partner Toshiba for repair.

    Good bye

  • Expansion of the files is at 27% and then my screen turns off? : s

    Hi all, I read the other thread on this subject on the website, but as usual the problem I have is simply a little more boring, I would like to re-Morphix vista compeltely but in order to do so I obviously need to go through this process. As the title says, when he reached 27% on the expansion of the files after the first reboot, it goes no further, then after awhile my screen turns off. IM typing this text from my laptop at the moment in the hope that all of a sudden my screen will restart and it will continue, but I doubt it very much.

    I understand more information may be needed to help me then please just ask. Thank you.

    P.s. This problem during one accurs installation from the cd rather than boot. When I try to boot from the drive and runing installing it, my screen turns off agan normally just after entering the cdkey for vista.

    I have no idea why this is happening, but if I have the sort I would be very very happy :)

    EDIT: A little later and the screen is back on, sound saying "Please wait a moment while windows prepares to start for the first time" then after that, there are a lot of points and moe points keep coming (etc.) I hope it's a good thing: S

  • iPhone 5 - can't turn off / reboot that can not enter password

    iPhone 5 - can't turn off / reboot that can not enter password

    Screen has the 'things to do' info partially down the top of the screen, unable to access the "forehand" (try but does not) to unlock, when press button on / off nothing happens (normally have to enter the access code, but cannot get to it!)

    Any ideas?  I'm leaving tomorrow at 04:00 to travel and NEED this phone.  Have a "Genius Bar" appointment at 05:10 this evening in a busy shopping mall but prefer NOT to have to do!

    A C & P is appropriate here...

    If it has NEVER been jailbroke, here are a few standard repair procedures:

    First of all, try a system reset.  He heals many ailments and it's fast, easy and safe...

    Hold down the power button and the Home button simultaneously until you see the Apple logo.  Ignore the "Slide to power off" text if it appears.  You won't lose any apps, data, music, movies, settings, etc.

    If the Reset does not work, try a restore.  Note that it is nowhere near as fast as a Reset.  It could take well over an hour!  Connect via a cable to the computer that you use for synchronization.  In iTunes, select the iPod/iPhone/iPad, and then select the Summary tab.  Follow the on-screen instructions for restoration and don't forget to say 'yes' to the backup and go back to iTunes on the computer (NOT iCloud) because it is more comprehensive.  You will be notified that all data (apps, music, movies, etc.) will be deleted, but that the restoration is complete, you will be asked if you want the backup content to be copied to the iPod/iPhone/iPad.  Even once, say 'yes'.

    At the end of the basic restore, you will be asked if you want to synchronize the iPad/iPod/iPhone.  As before, say 'yes'.  Note that syncs selection will disappear and the restoration will terminate if you do not respond within a reasonable time.  If this happens, only applications that are part of the IOS will appear on your device.  Corrective is simple – bottom right of iTunes, choose manual 'Sync '.

    If you are unable to do the restore (or it does not help), go into Recovery Mode according to the instructions here.  You will lose all your data (game scores, etc.,) but, for the most part, you can redownload apps and music without being recharged.  In addition, read this.

  • T420 screen turns off and turn it back on when the AC adapter / CC is attached or removed

    You are working on your machine, staring at the screen and the power failure... Yes - something quite common in these parts of the world... but no worries, the screen darkens slightly according to the diet plan and you hardly notice. Then, when the backup generator kicks in and the power is activated again, the brightness of the screen is back to your usual setting. Meanwhile, it is not a gene. Right?

    Well, that's what should happen... except that most of the time it doesn't work! Most of the time, the screen turns off and then turns on remove the main power and reinstall it. Note that this never happened once with T61 or T41p.

    Initially, I assumed it was because I had an external monitor attached... maybe it was to reconfigure something there? But then, it happens even without the external monitor. Then, I tried looking for the video driver updates... maybe this bug had been fixed to the... no luck there.

    So, finally, after having known this more often now, I thought I would get feedback from you all. Any advice?

    Check the Intel Media profile with the power settings. If a battery is "Maximum economy" mode then it should be in Exchange for 50 Hz to 60 Hz... Change it to balance or maximum Performance and see if its ever-changing from 50 Hz to 60 Hz...

    If all else fails, try updating the video driver, it might be a bug in the previous version of the driver.

  • Bluetooth freezes when the screen turns off

    Having a problem with the Bluetooth on my pre. I coupled it with a Plantronics Voyager 855. Initial pairing works very well, but after the screen on the pre turns off, the connection goes bad. When I turn the screen back on, the Bluetooth application on the phone always displays the connected headset, but it is not. If I try to play music, there is no sound, and if a call comes in, I can hear the person on the phone, and not on the helmet.

    About 30-45 seconds after the screen turns off, I hear the high tone of the headset which means that it has lost connection. I don't think that the headset is bad. It worked very well with my previous phone.

    If I have music when the screen turns off, the connection is very good. It's like, when there is no active communication between the phone and the headset, and the screen turns off, the bluetooth on the phone goes into a blocked State. I can restore the connection by turning off bluetooth on the phone and then on again. It reconnects to the helmet, until the next time the screen turns off.

    I tried this to get a better idea of the problem...

    If I remove helmet > disable bluetooth phone > turn on bluetooth on the phone > put the headset in pairing mode, it pairs fine.

    If I remove helmet > disable bluetooth phone > turn on bluetooth on the phone > turn off the screen > wait 45 sec > turn on the screen > put the headset in pairing mode, then it does not.

    Again, it is like turning off the screen causes the bluetooth of the phone hang. Given that the screen turns off fairly quickly, I basically disable bluetooth phone and back on every time I want to use it.

    Any thoughts?

    My problem is solved.  Turns out that I had a defective unit.  He traded last night, and it works fine now.  Got the yellow box this time.  First of all, we had the black cover.

    The swap was a little complicated.  I bought in a store of absolute Wireless in Garner, North Carolina.  It is a reseller of third party.  They did it to a Sprint service center to have a technician "certify" the default before they would replace it by car through the city.  And of course, the service center couldn't do the replacement, so I had to go back through the city to the point of purchase after they certified it.  Best of all, the procedure of "certification" involved explaining the problem to the technician for about a minute, she agreed with me that it was malfunctioned and his writing his employee with the ID on the back of a business card to bring back me to the first shop.  She has not yet turn the phone on itself.  She said pretty much the guy to the absolute Wireless has been a * beep * by sending me to it in the first place b/c, we could just do this by phone.  PITA BREAD.  But I suppose it is, that's what I to do not buy directly from Sprint.

  • LCD screen turns off after a few minutes

    My screen turns off after a few minutes, even if the parameters to be able to say that he should turn off after 60 minutes of no activity.  Before this date should activate the screensaver after 10 minutes of no activity.  But in my case the active screensaver ever and my right monitor fades to black.  What can I do to fix this?  Is there a registry setting that has changed I don't know?

    -penciline

    I checked power options, the first thing, and then I checked the (NVIDIA) graphics card Control Panel to see if there is a setting for it.  The figures that I had in my previous post came from my power options, but I don't know how standard power who do not have the numbers that it would affect the schedule/performance options.  I went to advanced settings.  But I also rebooted my computer which solved the problem, in my opinion.  I'll have to sit and wait to be sure, but I'll get back to you on that once I have test.

    Hello Ivan,.

    Thanks for the quick response.

    Before we started we the troubleshooting steps, I would ask you to answer the following questions.

    1. What excatly do you mean when you say "this time, it was at stake?
    2. What kind of game you are making reference to?
    3. What is the number and the model of the computer?

    This problem could be related to corrupt or outside the drivers of graphics cards dated, I would recommend that you uninstall then reinstall the graphics card device drivers and check if that helps resolve the issue.

    Here are the steps you can follow to solve the problem.

    Step 1:

    I would recommend that you uninstall the device of the graphics card from the Device Manager, and then reinstall the latest version of the graphics of the website of the manufacturer driver.

    1. Open Device Manager.
    2. Double-click the type of device you want to uninstall.

    3. Right-click on the desired specific device, and then click Uninstall. You can also double-click on the device and then on thedriver tab, click Uninstall.

    Step 2:

    Once you uninstall the device of the graphics card from the Device Manager, uninstall the drivers for the graphics card from the list of programs in the control panel.

    To uninstall the device driver, you must follow the same steps that you follow to uninstall a program in the list of programs. Please go through the article provided below for more information on the same.

    Uninstall or change a program

    Step 3:

    After uninstalling device drivers in the list of programs, download and install the latest version of the driver from the manufacturer's website. Do a search using the computer brand and model to get the correct drivers.

  • Access code is lost as soon as the screen turns off

    When I turn my wrist after that my Apple Watch screen exploded, I need to enter the access code. I turn on the wrist, the screen turns off, I turn back, screen lights up, I need to re-enter the password. And so on and so forth. The watch does not maintain the code.

    I am white white, is not dense hairs on my wrist, no tattoos and I wear the watch very well on my skin.

    The funny thing is: it is a replacement watch, I got today. The other had the same problem, but this is probably because the bottom of the watch with the sensors fell, must have damaged the sensor cable. But this one is brand new.

    Make sure the wrist detection is enabled:
