[Q] Blank screen, no lights, non-responsive and appears dead but... - Xperia Z Q&A, Help & Troubleshooting

I've had my Xperia Z for 2 weeks and have been happy with it so far. However, I has cause for concern last night when I found it "dead". About an hour prior, I checked to see how much power it still had in order to decide whether to connect it to the charger. I found it still had 76% so decided that I didn't need to. Then an hour later I picked up my phone and found pressing the Power button had no response. It just had a black screen and no lights. I held down the Power button thinking it might have just powered off but also no response. I then connected the charger and waited and holding down the Power button also nothing happened. It just was dead. On previous Android phones I would try taking the battery out but of course couldn't do that with the Xperia Z. It has not been dropped at all and not been rooted so I got worried that it had died within 2 weeks of very little use. I looked online and found someone had a similar problem with an older Xperia (T or maybe U) and they managed to switch their phone back on by holding down the Power and Volume buttons. I tried this and lucky my Xperia Z came back on.
My question is, has anyone here had a similar experience? Or know what could possible have caused it. So far it's been fine today but I am somewhat concerned that it has happened and that it could well happen again. I bought it online from the Three UK website as a PAYG phone. Do you think I should contact them for a replacement or do you think this is a problem with all Xperia Z's or it's firmware.
Thank you.

Hope it's a one-off issue.. Get a replacement it were to happen a few more times again, especially since you're running unrooted on stock! You could try re flashing your firmware using seus to see if that solves your problem, if it's corruption on the firmware/nand side, especially since such sleep of death cases on the xperia z isn't common on the xperia z as of now.

it happens for android phones often
but thr s no absolute dead for xperia phones like wht happen for galaxies.
anyway if u have warranty as u know don worry and change it

this is prolly a bug in jelly bean xperia V also suffers from this and the issue is known as "sleep of death" you can search xda or google for it
hopefully it will get fixed in the next update which is comin "end of march"

Did you on stock ?

Hi,

Blank screen, no response to power button. Howecer when I plug the charger Led turns on red.

Volume up+power for 10 seconds.

Yes held down Power button and Volume up until the phone responded with a vibration and then it proceeded to boot up. Yes i am on stock. Nothing modified at all. I don't know whether to be relieved it is a known issue albeit on an older model Xperia or concerned that despite this is Sony's latest flagship device they didn't fix it before release!

Xperia Z Froze - Reboot

Hi there,
Just signed up to post something here as I couldn't find anything to help me online when I had a problem, My Xperia Z decided to freeze up this morning after locking itself, then it wouldn't respond to just turning it off, the Green LED was constantly on but the screen was black.
So to reboot the phone I just had to hold down the Volume Up and Power button for a few seconds, then it rebooted.
Obviously this wouldn't take people very long to figure out but I thought I'd post it up any way.
Cheers
Thanks

As with any new device, there are nearly always teething problems and I expect Sony will quickly issue an update to it's firmware as do many other manufacturers if it finds a problem....not had any trouble with mine yet, but I did only get it today......fab phone wouldn't go back to a Samsung due to their too plasticky construction....sorry Samsung !!! Free Sony headphones are pretty good too !!!

Xperia TL Screen doesn't turn on!

My AT&T Xperia TL screen isn't turning on. It happened all on a sudden. Phone is all stock - never been dropped. Phone still works as I can hear camera shutter clicks by pressing the camera button. I can also hear other notification sounds. The display itself just doesn't work. Interestingly, I saw the backlight once or twice during startup as I restarted it 7/8 times. Screen never came on though.
Already repaired twice through PC companion - didn't make any difference.
Any help would be appreciated!

Take it back to the shop. If its stock, not been damaged and you have done the official repair, get them to replace it.

Thanks! Problem is I have to ship it to their repair center and it'll take a while to get my phone back. I was wondering I could probably try out something on my own if it's some kind of software glitch. Even though, it's more likely to be a hardware issue - then I'm gonna have to take the longer path.
I'm a bit of surprised. This is my 10th Sony (Ericsson) phone in last 5 years. I have never had any issue till now and I really take good care of my phones.
Did anybody experience this problem?
I have not seen any threads on here work a similar problem
Sent whilst sat on the toilet.
Try holding all the buttons for 10 seconds or the power button alone if I remember. This happened to my brother once and had to perform this to get it back working

I've got the same problem with a Xperia T! The annoying thing is that the phone has just come back from the Sony repair centre.... Never had this problem before... 3 or 4 times in a day the display doesn't turn on and I have to force a soft reset, but the phone still vibrates, still receives messages and the notification LED works! I guess those idiots messed up with something during the repair.... It's gonna be the third time i send them the phone and they keep giving it back with a different problem! Tired of these retards, I hope that they can give me a new device... This one's fu**** up...
It's probably a software related issue, as always

Dead within 8 hours of use (dead dead. not battery dead)

ok so i've been using it a bit but my battery was 70% last i checked. was playing around with throw and just opened youtube and the screen flickered a bit (black lines) then decided to go black completely.
nothing i do will make the screen do anything.
holding the power button for ages (usually the way to turn off/reboot a phone) doesnt do anything. the backlight is on as i can see that. but nothing is on the screen.
anyone got any ideas on how to force a shutdown/reboot on these?

IIRC the Xperia Z1 has a hard reset button under the sim flap, it's a small red button, give it a shot.
remove sim card and sd card and try again, if it's still not responding do an update repair using SUS or PCC
BTW there is a known fault with the XZU and it could also be on the Z1 as they use similar Firmware, what people have found is that the phone will start up eventually and then they go into the display setting and untick the auto backlight option and that fixes it
I also reboot my Z1in this way when it blackout.

Had the same issue called Sony, push hard reset button all is fine in the world. Known issue Sony is working on it

Managed to hard reset using power and up volume .
Put it on charge overnight but it doesn't see,m to have taken any charge at all....just trying again using diff PSU and cables but it doesn't want to charge. It recognises that I've out a cable in as I played with the smart connect setting. When it is off completely I get a red light (presumably meaning its charging ) but not in android
Any ideas?
Got it charging again by pushing the red button near sim slot for a couple seconds.
Just had another issue with SD card not being recognised after I removed another (/safely) had to reboot again using power plus vol up as it stuck on the shutdown logo when I tried to power down'...
Wow I can't believe the amount of issues I've ran into within 24hours of having this thing. I really don't know what to do...return it because it sounds like a faulty device (but all the issues are seemingly unrelated) or return and get another phone (is anyone else getting problems like I am?)
Sometimes phones have issues. I got one once that had no speakers or Mic inside... it happens lol
Try to go exchange it, and see if the next device gives you issues.. if not then you're good, if it does pick a different phone..
Do it soon though, most carriers only have a 14 day exchange period, and then after that will charge you all sorts of fees and try to fix your phone rather than just giving you a new one....

sounds like a similar problem I had with my 64gb SD card - as I mentioned above remove all cards then start from there - a reflash of the firmware might help also

Something happened to mine with Youtube too. I'd started a video and paused it on a frame for comparison with another screen. While I was setting the other phone up, the screen on Z1 timed out. I pressed power, the screen come on and flickered, then went black!
Power and both volume keys function the same as the red button under the flap. I wasn't able to reproduce the bug.

yeah i've been trying to reproduce it and failing to. very odd. maybe its something to do with the first time you use youtube and do something specific?
gunna phone o2 up tomorrow and see what they say about all my issues. seems to have been fine this last 24 hours though and in their eyes that is prob reason enough not to issue a replacement.
I've had mine since Monday and this happened to me yesterday. I was troubleshooting sending MMS with T-Mobile tech support (not a phone issue as it was happening on previous phones too) and had to restart the phone several times. I noticed upon restarting that the backlight seemed to be on but the phone was not booting up. Had to perform several hard resets (both with the red reset button as well as the power/volume up buttons) before it FINALLY rebooted and stayed on. While trying to figure this out I ran a Google search to see if others were having this problem. One solution was to make sure the backlight option is checked. I had been messing with settings the night before and must have unchecked it. Since I rechecked it I haven't had the same issue.

[Q] Black screen of death ? Any survivors ?

Hello all,
I own a Z3 Compact since now 4 months, I bought it abroad, in Qatar and went back to Belgium after.
Overall, I'm very happy of it. Nothing to say.
Yesterday, the phone was almost full in battery, connected in bluetooth in the car... I tried to pick it up and turn it on, it wasn't working anymore. The screen stay black. I tried to turn it off, then on, impossible.
I tried to push the vol up and down then power button all together during 30 sec, nothing worked.
I tried to press the yellow button near the sim card, nothing helped.
I also tried to do all those combinations with the power plug connected, but even the power led is not showing up !
The phone seems to be turned off and I'm unable to turn it on again. I've read some forums and it looks like it's a common problems with Sony Xperia phones (ex: Link).
The date on the paper near the sim slot says 14W36 (Year 2014, Week 36).
I'm wondering if I should return the phone to Sony for warranty ?
If yes, do you think it will work even if the phone hasn't been bought in Belgium ?
Thanks
Tried Sony's FlashTool ?
Hi,

Hello,
The phone doesn't even get recognized by any software on the PC.
Anyway, the phone will be returning in waranty tomorrow morning, I'm crossing my fingers.
Such problem makes me really wonder if these phone are worth it.
Hi,
The phone went back in warranty in a Sony repair center in Alsace (FR).
They replaced the motherboard, not the phone is working perfectly.
I hope I won't have the problem again.

Take it in for warranty m8
Might be worth waiting for the battery to completely drain and then try and turn it on after getting some charge in it.
I've had problems recently, after using OTG, the tab's display will just turn off, and when I mean off, it's just the screen, the tab is actually still on, as you can feel the heptic feedback, the only way is to force reset using the power volume and home key.
Another problem, still recently, I had about 12% power, so I just connected the USB to charge the tab, the screen started to flicker and then nothing works, after 10 minutes reconnected the power, and it started to charge up from 0%, it seems like the tab has gone haywire, I had decided to trade it in the next few days for the xperia X performance.
Not even bothered to take it to samsung service center (still under warranty), I can't stand their customer service, my tab has been through a repair before, my home key died and it kept on grabbing the side of the hole and sticking down, they replaced the part, but left something inside causing a lump at the back, problem sorted out, but the buttom kept on grabbing the side of the hole and not coming out if you press it slightly on one side, I even showed them the problem, and they agreed, and they say that a normal person won't press the button like that, and it's normal, I did mention that I have tried a few units and does not have the same problems, they just said it's normal, so I said to them if this is normal what isn't normal, and do they tell all there customers if they have a problem that its normal.
So I am completely sick of there BS, trying to keep away from samsung stuff.

Got rid of it, it should be a problem internally, anyway I've traded it for a Sony Xperia X performance.
Mine also died few days ago. I tried to charge it with different chargers and cables but without any success. POWER +VOL DOWN is not rebooting the tablet.
Now I am planning to open the back cover and will try to disconnect the battery. I believe it will help.
