Handset screen goes black every now and then. The issue persist not for all the time I could use the phone continuously for at least a week without any issues. After a week or so black screen shows up but apps are working in the background. Tried updates , Power + Volume Up buttons and so on ,everything went in vain. I switched off the phone for three days and used it again normally for a week before the black screen issue again comes up. Every time I got to put the phone for complete rest two or three days before using it normally. What could be the real issue here?
Hi, my Xperia P is old and goes black screen couple times. The only solution I've ever done each time is to push Power + Volume Up buttons, and then the phone recovered. Perhaps my phone is not as seriously old as yours. Wish someone could be there to help you, good luck.
My phones goes to deep sleep too, only thing helps is hard restart.
I have no idea what is causing that, I reflashed so many kernels and roms and it didn't change the fact phone is failing me.
I had the same problem, the display connector got loose on the inside.
Had to open the phone and reconnect it properly, now it's working fine again.
I had a similar problem but I did not face it that frequently as you... A temporary solution is to press Vol Up + Power button simultaneously and let it reboot...

How to reconnect it ? seems like hardware issue. Btw sorry for the late reply.
Just pull it off and then back on, that should fix it.

Hi. The phone application was not functioning well and the F/C dialog showed up. I powered off the phone and from that point, the phone won't turn on.
The battery was fully charged before this happened.
When I press the power button, the phone vibrates for half a second, the screen brightens up but does not show anything but a black screen.
I removed SIM and SD cards, removed the battery and performed the above steps but nothing happened.
I also tried to put on the charger to see what's going on. Once I plug the charger, the phone's screen brightens but shows only blank (even without pressing the power button)
When connected to the charger, the green light for charging is on for some minutes, then goes off automatically.
I tried to connect it to the PC, and PC Companion finds the device as usually. It even shows the dialog on the pc screen to mount the device.
I tried a hard reset, but does not work
On some point, the sony logo appeared and then a dialog saying: "sorry process system is not responding". The first time I pressed Force Close and the phone turned off. Immediately after that, the phone turned on and showed the exact message. I pressed "Wait" but nothing happened in the next 15 minutes.
I called Sony's support center and they suggested a software update. Did the process exactly as it should, but again, even after the software update the screen shows nothing but black. It is all the time brightened for some reason.
I tried to turn off the phone for some time by removing the battery, but as soon as I put the battery back on, the phone's screen brightens and stays that way forever.
The phone was functioning perfectly up until this issue. The only application I had installed apart from some games, was AWDLauncher. On the screen I had only a TASK widget and a battery status widget.
The phone is 3 months old and has been always in perfect condition.
ANY help would be appreciated!!!!
Many Thanks

I tried the steps found in the link you gave me, but I couldn't go any further after step no (5) from the tutorial, as it would require to enable Debugging mode and I cannot access the OS (since the device won't turn on).
Is there a way to format all the contents of the device and have them replaced by running SEUS (as it always says that my device is up to date now)?
Was it this:
http://www.sonyericsson.com/cws/sup.../detailed/updateservice/xperiax10?cc=gb&lc=en
That Sony Ericsson told you to do?
If not, use that.
Download it, follow the steps when it says you have the latest version, press "Install Anyway".
Hope this works.
Hi itTim. thanks for the response
this is what i did but no improvement at all ((
Sounds like you broke your LCD screen somehow.
That would suck because I broke mine and it cost me $200 to fix.
Hi Hypercore.
Yes that could be the problem. The thing is that I always took rally good care of the phone, always carried in a leather pouch and never droped it. How sensitive is this lcd anyway?? Did you notice any cracks on your lcd or was the problem simillar to mine?
Thanks
When you turn on the phone does the lcd backlight turn on?
If so, look for any faint lines of color (usually a hairline size). If you see any of those then your screen is cracked.
the backlight is on, but there are no lines of colour on the lcd screen.
another weird thing is that the green light on the top blinks one or two times every time i put on the battery. even if the phone is off, once I insert the battery turns on automatically after a couple of seconds.
If all else fails you could try to flash back to your original fw with the tools here:

That won't do anything.
I had almost the same issue. Nothing worked. But, when I removed the battery and left it for a day (24h) without it, it just started working again. Still working without issues..
Good luck!

Phones are very wierd pieces of technology. I once bricked my k610i and that's a phone that's supposed to be impossible to un-brick, but out of nowhere a month or so later i picked it up, hit power and it turned on perfectly. Made no sense at all, but it worked.
Taking the battery out for a long time probably took all the electrical charges from it (kind of like how a computer power supply / monitor can hold power charges) and reset your handset.

Indeed. It could be a frozen chip, memory fault, power-regulator and so on.

if you have done this and did not worked , then it is the LCD.
send it to workshop and check it there.
Guys i Really need the solve of this problem , my xperia has blank screen now without backlight and the phone completely doesn't work . when i put the battery and prees the switch botton it gives me 3 red signals , i've updated and hard reset but it didn't work , and btw the LCD is fine , any idea. did removing the battery worked???? . please answer
After a looooot of time since my latest post, finally my Xperia came back to life. There was a battery failure which means the phone was ok all the time. Weird thing is that the led light showed that the battery was charging ok. I removed the battery and after a lot of time it is working ok again. This was really really odd.
FYI for anyone else that gets this issue.
I just had this for the past hour after trying to change my baseband....could not get it back for anything.
What I did finally try was run another baseband via flash tool, connected to usb and it started flashing....after flash phone powered on again...yeah I agree with everyone, that is freaking scary when it happens.
Hey,
I've had my Galaxy S3 for around 2 months or so now and I upgraded to the latest UK firmware the other day (XXBLG8) via flashing in Odin.
Around 3 days ago (Just after I flashed the ROM) I noticed a problem where when I tried to lock the phone, the screen would only dim and from that point the touchscreen would not work whatsoever. The phone would only undim the screen whenever I touched the lock button or home button. The capacitive touch buttons don't respond either. When I press the power button again, it just dims the screen once again. The screen will go off after a little while, but the only way to get my phone back is to hold the power button down firmly for around 10 seconds to kill the phone altogether. I then restart it, the phone works as normal. It doesn't have this problem EVERY single time I lock the screen, only once in a while, but it's happening every day and it's ridiculous.
This is only occurring on the new ROM from what I can tell. Has anyone else had this problem, or do they have a solution to this dumbfounding issue?
Thanks
- Ross

re-flash the rom and if it persists flash again. Sometimes phones like to be fickle buggers hope this solves it :fingers-crossed:

Yeah, will probably do that within the next few days if there is no solution. I'll backup using CWM to my SD and then re-flash if the problem persists. I can't be bothered to set up a fresh AGAIN for no reason lol.

I had a similar issue 2 times with months in between , no response from power+vol up , no lights when charging , no response from pressing on the red button behind the flaps, last time it happened after a reboot from an update and still having plenty of battery left.
I tried putting it on the charger for a whole day with no result , put it back in the box to return it , decided to let it rest a few days first , since someone had the same issue and it magically came back to life when he got back from a vacation.
So i try to turn it on 2 days later and it worked again magically indeed, functions totally restored till this day.
Hope this helps a bit

If it's like the Z1 Tablet you could try a complete power down by pressing the volume up/down, and power button for several seconds, then try to do a recovery via the Sony PC companion (so long as you can get into flash mode), if it works you'll loose all data, but it's worth it IMO

I've got something like this going on too. Plugging it into a blackberry playbook charger seemed to give it a charge when the OEM charger wouldn't work. It came back to life. I've also noticed that the tablet won't sleep properly while charging. I plug it in, hit the power button to sleep, and it wakes it self as though I plugged a charger in. And so I cycles dimming the screen to sleep and then seconds later like u tap the power button to get the screen to wake. Something s definitely wrong.

I'd the same on my SGP511 yesterday when rooting failed. Just charge for an hour using Sony charger, then press POWER + VOLUME for more than 60 seconds. It vibrates three times and resume from death. Cheers!
It seems like some of these boards may be failing. I think this issue is related to the screen not powering off while charging issue. Users are reporting that Sony is repairing the devices by replacing their main boards. I wonder if there is a known issue with z2 tabs that Sony is aware of.
My z2 tab has both of these problems. I flashed a factory ftf to it and it still had the problem. This is what led me to believe that it was hardware related as it didn't used to do it running cm11 or stock firmware.
I had this happen to me once or twice, though in my case I could recover via power + up/down (can't remember lol) .
In the end my tablet developed other symptoms (namely inability to magnetic charge, and screen stays always on when charged) so i sent it off for repair and they replaced the motherboard.
Hasn't happened since, though I only have had it back for a few weeks. Touch wood.

Does replacing the motherboard mean fully stock and locked boot loader with present DRM keys?

Yep as in these tablets the flash/CPU/RAM etc. is baked into the mobo so its more or less getting a new tablet internally.
to my shame I updated it without remembering you can only root the older firmware which it did come with ROFL.... oh well the only thing I use root for is adblock

Can't you just use flashtools to downgrade your tablet back to the rootable 4.4.2 firmware?
I managed to downgrade my xperia z2 4g tablet with flashtools application.
Only hiccup was that i accidentally put my tablet in bootloop while i tried to downgrade it, after that i just rooted and installed dual recovery. With that dual recovery i could flash pre rooted 4.4.4 and so i still have my drm keys and ps4 remote play app.
So about 3 weeks ago, I dropped my HTC so now I have a large crack running down the middle of the screen. However I haven't had any other problems up until last night. The ringtone volume turns itself up without me even touching the phone every now and then and once it does that, the power button stops working. But it does work again once the screen is switched off, meaning I can turn in on but not off. The power button functions fine until the volume button acts up the first time after restart.
I factory reset my phone thinking it may have had something to do with the software but the problem came back within the hour when all the updates started rolling in. Once it did, i booted it into safemode and the problem seemed to stop but I don't know what's causing it. Could it be an actual bug in an update or is the damage to the screen simply too much for the phone itself? Has anyone ever dealt with a problem like this? Any help will be appreciated as I know it's expensive to fix these things and I don't want to go to the shop to get it fixed only for the problem to come back as it's software related.
Hi,
Just few minutes ago my brand new phone just broke on me. I was holding it in my hand, locked screen, like minute later I tried to unlock it to no avail, screen just stayed black. There was a sound when I touched it by the fingerprint sensor, but no light up from behind the screen. I tried holding down power, then power+volume up, phone only vibrated, no reaction on the screen. I've connected it to the charger, and now it seems to be in bootloop - screen is turned off, and every few seconds phone vibrates. I've managed to somehow turn it back on once, phone booted to system, everytthing worked just fine, then I locked screen and it just stayed black, now I can't reproduce that, can't even turn it off, it's just vibrating every so often. Did it really brick in my hand? Software of Hardware? Everything worked just fine, maybe battery was draining a little bit too much for my taste, (15-20%/hour with screen on+lte/wifi) but 120Hz refresh rate+bright setting and AOD turned on 9am-9pm could do that. Do you guys have any suggestions, or I'm expecting trip to the service?
Sorry, but i cannot guess any reason. I am stumped as this bootlooping shouldn't beb happening... Very strange. May be its better to show it to service center guys.
Btw, i had tried this on my previous android phone to shut it down, like a hard shutdown. I had pressed power + volume down + volume up keys together to shut it down completely. Basically by pressing all the 3 keys. If you want to try, you can try it. I have not tried it on my GT, but had used it on Oneplue 2 and Honor View 10.
Hope your issue gets resolved asap...
Okay, I've contacted support via livechat, they told me it's definetly just software glitch, and to resolve this I have to wipe dialer cache (?) and all system settings - I did it, everything worked just fine, but today, again, same thing happened. First time phone just died in my hand, second time it was while listening to music via Pulsar, today I was just sharing wifi as a hotspot, phone randomly broke connection and would not unlock, but still I could tell it was on, because of vibrations and sounds. Not a software glitch after all? If I manage to unlock it I'll just recover it to factory settings, we'll see if that helps, but I don't like the sound of that.
What apps are -you- installing?
Launchers and power management apps are prime suspects...
Otherwise, mobo failure. It may be firmware but how far do you want to take it?
It should run fine out of the box.
Last time I played with launchers was with good old SGS about 5 years ago, only app out of ordinary was AccuBattery to check that SoT drain, but could it make such a damage without root privilages?
