Help!!!! Xperia Z2 Screen flicker then gone!

I just bought new Z2 12 days ago. Today when i am trying to use the phone, the screen backlight start to flicker from strong to dim for a moment...after i try to adjust the brightness to lowest, the flickering stop. Then i readjust the brightness level to higher level, the screen start to flicker again for a moment then totally gone.... when i connect to sony tv via mhl cable, the phone funnction work perfectly as displayed in tv with touch screen function on the phone, just that no picture on phone screen or is it due to backlight problem? Really feel disappointed with sony....

I apologise for the late reply; there could be a number of reasons for this however it would be worth at least ruling out a software issue by attempting a software repair:
1. Download the PC Companion software from http://www.sonymobile.com/gb/tools/pc-companion/
and install it on your PC.
2. Install and open PC Companion then select Support Zone.
3. Phone Software Update.
4. Start.
5. Repair Phone
6. Continue
7. Accept data removal
8. Next
9. Wait for prepare
10. Select Phone
11. Follow the connection steps

  • Screen Flicker then Fade Pavilion dv6t

    Hi,
    I have had an HP pavilion dv6t-6b00 for about 1.5 years and have been running Windows 7 since I got it.  About a month ago, I started having issues with the screen flickering (horizontal lines appear sporadically on the screen, and then the screen displays the same image, and then starts to fade and will fade to black unless I bend the screen).  Bending the screen refreshes the display, but usually immediately after bending it (grabbing the side of it and rotating it toward or away from me) the display starts to 'freeze' again.  Also, I only notice this issue for about 2-10 minutes after first opening my laptop.  After 10 minutes of use, I don't have these problems anymore and I can use the display normally.  Going down the page is what I witness in real-time over the course of a minute or so.  And, yes, the issue definitely started before I took off the display cover and opened it up.  I just did that today.

    Did you ever get this fixed? I have the same issue on the same computer. I ordered a replacement screen cable to see if that'll fix it (I'll write something here if it does in case others have the same problem). My problem has been really odd in that I was sure it was a hardware issue for a while (if I bent the screen the right way it fix it for a little while). Then I uninstalled a program (I was using a monitor), and the laptop screen immediately turned on and worked great for like 5 months -- suggesting its a software issue. However, now its back to being unusable.

  • Lenovo G530 laptop screen flicker

    I have a Lenovo G530 laptop that has an issue with screen flicker that is getting worse. The computer screen will start going thru a crazy screen flicker then will stop and start again. I have already checked cable connection to lcd on motherboard and reseated connection of lcd to motherboard located under the keyboard as someone suggested in another posting I found online that resolved issue for them. I am starting to think it might be a bad inverter or screen because I have hooked up laptop to external monitor and it is running fine with no flickering happening when the flickering is occurring on laptop.
    I am attaching a link to a small video I shot of the issue as it is occurring on laptop screen.
    Does anyone have any further suggestions?
    Bad inverter or screen?

  • HELP?!? - iMac 2011 i7 Screen Flicker issue (OSX 10.8.3)

    I have a Mid 2011 27" iMac with i7
    Since the latest OSX update (OS X 10.8.3 (12D78)) I am getting a very concerning issue where my secondary monitors and my iMac screen 'flicker' and show horizontal bars (green in colour) the audio then seems to stutter and crash before eventually the computer freezes and I have to hold the power button to shut down.
    This happens once or twice a day, however a related issue that happens every few minutes is that just my secondary monitors flicker white in places and go completely black for a few seconds at times too.
    I have run the Apple Hardware Test and it reported no issues, I also reinstalled OSX from recovery and it is still happening.
    I am hoping (praying) this is an issue with OSX and not my hardware. Can anyone shed any light on this - I'm seeing reports of 'similar' sorts of issues with the latest OSX update. But nothing like the issue I mentioned first (the one that forces me to shut down)
    I have a Time Machine backup, is it possible to use Time Machine to revert my OSX to 10.8.2 to see if it is indeed the OS that has the issue?
    Thanks for any help you can give!!!
    Jay

    Hi, I'd try the 10.8.2 restore.
    I never use it, I use cloning myself, but...

  • Qosmio F10-124 - Pixelated screen, flicks into blank, then comes back to normal

    It looks like the graphics hardware has failed on a pc bought in April 2005.
    This occurred in stages, starting from around the time when I received
    1) An automatic download of windows updates and
    2) And Adobe upgrade.
    In Sept 07. Do not know if this is at all related with the screen malfunctioning.
    The screen has at best operated intermittently, with only access being possible using the external VGA port.
    The latest Toshiba screen drivers for the WMD operating system did not rectify the problem.
    In the last couple of days pixilation has occurred in various parts of the External monitor screen, whilst the laptop was just blank, up to that point the external screen was displaying my work just fine. Occasionally the laptop screen flicked into life and the pixilation has become more prevalent recently. The occurrences of the laptop screen working were random.
    I need to have the screen settings such that the external monitor is a mirror of the Laptop screen to do anything on the laptop.
    Rebooting the PC has no effect.
    The latest symptoms are that the external screen shows that the OS has booted, but there is an alignment problem causing a pattern to appear across the screen, and this is "ghosted" ?? with several iterations of all screen events across the width of the screen output. The Laptop screen is not working at all at present.
    Anyone have any ideas what could have caused this, and/or how to fix it??

    The graphic card chip seems to malfunction. Your described issue sounds really like a chip fault
    But please note that this is only my personal assumption and if you want to be 100% sure whats wrong then you will have to contact the service provider in your country for a detailed check.
    In worst case the motherboard must be replaced because the GPU chip is fixed on the motherboard and cannot be removed.

  • 17" intel iMac screen froze then has gone completely blank. Any ideas?

    Hi There,
    My 17" intel iMac screen froze then has gone completely blank.. 
    I've done a SMC reset to no avail.

    If it won't startup in Safe Mode, then try Startup Manager or the Apple Hardware Test from your original Install Disc.

  • HT3775 I just upgraded my ipad to 6.0.  I can no longer expand my audio files so that I can move forwards and backwards.  I used to get a diagonal arrow to enlarge the screen and then have a bar that I can move to navigate. Can you help?

    I just upgraded my ipad to 6.0.  I can no longer expand my audio files so that I can move forwards and backwards.  I used to get a diagonal arrow to enlarge the screen and then have a bar that I can move to navigate. Can you help?

    Hi James,
    I am listening to embedded training files on the Quick Time player (I think). They cannot be copied to protect the information.  You only have the option of listening.   I used to be able to click on the Q in the audio strip and it would provide a diagonal arrow and this would allow me to expand the bar to a full screen. I then had the bar which would allow me to navigate in case I wanted to listen again or in case I wanted to move forward.  After my upgrade, I can no longer expand the strip to a full screen with the adjuster.  Now I have not chance to take a break in listening to these audios and most of them are at least an hour long.  Thanks for your help.

  • TS3694 My phone keeps freezing, the apple sign appears on the screen and then it freezes again and repeats itself.. has anyone had this before? it's also not letting me restore it from iTunes, it keeps coming up with error (9) or error (14).. help?

    My phone keeps freezing, the apple sign appears on the screen and then it freezes again and repeats itself.. has anyone had this before? if so, what is it? & it's also not letting me restore it from iTunes, it keeps coming up with error (9) or error (14).. help?

    Hi there Holly N,
    You may find the troubleshooting steps in the article below helpful.
    Resolve specific iTunes update and restore errors
    http://support.apple.com/kb/ts3694
    Configure your security software
    Related errors: 2, 4, 6, 9, 1000, 1611, 9006, 9807, or 9844. Sometimes as a result of this issue, a device might stop responding during the restore process.
    Check your security software and settings, which can block ports and prevent connection to Apple servers during update and restore.

    A minor point, but it may avoid a little confusion if, instead of saying "black" in reference to the iPhone 5s, say "space gray":

  • IPad 2 screen flicker when quickly sleep then wake. can people test this on their iPad 2?

    Hi.
    As the title says if i quickly press the sleep/wake button a few times quickly there will be a screen flicker with lines on the screen for a split second, can people test this for me to see if it's software related? 3 of the 5 ipad's i've tested this on has the issue. Does your iPad 2 do this? thanks

    This is happening to a lot of iPad 2's. Glad it wasn't just me.
    I had my first iPad 2 from the uk launch day and I was disappointed when I realised mine was showing significant lines on the screen when it was activated. It gradually got worse until the point I had to take it back tothe retailer I bought it from (comet uk). I was appaled with their 3 DAY retun period. But, after a loooooong phonecall to their head office and AppleCare and with a great deal of arguing they gave my money back. I then bought one from the apple store. Got home and found that the SAME THING was happening. But worse.
    Took it back yet again and got another that finally works.
    Just to let you all know it is a hardware fault and it isn't normal. Take it back to wherever you got it. It isn't a software glitch either as I updated to the latest at the time with no luck. Tried wiping all my data off it too with no luck.
    I've lost my respect for my iPad 2 and apple as it's ridiculous that everybody hypes the products and then when you spend all that money it doesn't work. Third time lucky though, eh?

  • Screen flicker help - Mac Pro

    From very early on my Mac Pro has had an issue with screen flicker.
    It's more noticeable when under load but can also happen with just Safari open.
    Steps I have taken so far to try and fix the problem have been thus:
    1. Upgraded from 10.4 to 10.5 OSX
    2. Upgraded Video card to the GeForce 8800 GT 512 MB
    3. Added more Memory, I now have 7GB
    4. Added new Hard Drive and made a new install
    5. Reset the PRAM more times than I can count and also did a memory check.
    All of these steps I have taken so far have failed to fix this problem and it's really starting to get on my nerves.
    My latest idea was that it may have been something to do with the extra memory I have added over the past two years. All the modules have the same spec, 667MHz DDR2 FB-DIMM but I had a thought that there might be some incompatibility issue going on with that as some are from different manufacturers.
    Could this be the case?
    Also I hear from Apple Insider that an update is due soon that will carry a large update for the graphics side, will the update cover this type of issue I and some other people on here are having?

    It's not heat related as it will do it from cold. I also make sure I keep the inside nice a clean with a clean out every month or so.
    My first thoughts was also the cable but I have got it far away from all power cables and all transformers are at least 1m away from it.
    I have moved it around using two different ring mains but still get the same issue.

    You buy one and only one download.
    As it should have been transferred to your computer when you synced, you can contact itunes support and ask for an exception.
