Screen goes black, couldn't wake it up - Sony Ericsson XPERIA X10 Mini

Hey guys,
I thought You could help me to solve it. I have this problem on my xperia x10 mini pro. When the screen goes black automatically I can't wake it up (tried all the buttons, still black), so if I want to use my phone I should reboot it by taking out the battery. Then it is working fine, till the screen goes black or I lock it. This problem only appears when the screen stays black longer (30min to 1h). I tried reinstalling the software with Sony Pc Companion several times, also bought a new battery, but it didn't help me. I'm wondering if anyone else have this problem? Thanks for your answers and sorry for my english.

You have this problem with the Stock ROM?

My phone was rooted when the problem appeared, but now it is happening on the stock room too (I have flashed my phone several times using sony pc companion).

plz help mine is an uprooted live walkman !!!
plz help ????
It was probably only a display problem. Maybe it didn't show anything but the phone was working fine. It can happen sometimes.
Worry about it if this happens again. Probably it switched off dut to depleted battery.
Sent from my WT19i using xda app-developers app

maybe its just a normal minor and not harmful error . but you could open it again and its working fine i think its not an issue

it was not battery discharge it just turned off and and when I re inserted the battery it started working normal !!!! I think it might be due to memory card or some sim problem but plZ experts help me out
Let me repeat that: I think it was not shut down. Simply, the screen stopped working. So you thought it was shut down. And of course trying to turn it on wouldn't work, since it was already turned on.
Removing the battery forced the phone to shut down, and the screen started working again after turning it on. This also happened to me once.

it was not that because on pressing the the lock key and home key the lights of touch buttons did not turn on plz hep !!!!!

Ok. Whatever. But then, what kind of help do you need? We all told you not to worry, unless it happens again.

i justvwant to know that has this thing happened to someone else ??? and what exactly could be tthe problem ???
This sometimes happened to me when I switched to a custom kernel (KrSH) and overclocked it to 1.2GHz. Noticed it happening after opening a few different apps or while receiving a call, but I can't duplicate it myself using controlled actions.
Might be helpful telling us what you were doing on the phone when the abrupt reboot happened.

im unsure what can cause this but there are some posibilities
here is a list:
malicious apps
advertising apps
badly designed apps
try removing some apps that have been recently installed, if the problem persists then repair your device using support zone found within Sony PC Companion
Finally someone with the same problem, i bought my Z2 last week and i am feeling that the mobile takes long to start up (like 10 seconds) like pressing the button to vibrate, after vibrate is quick, with or without extra apps, its weird, anyone else feeling these?

[Q] display bad?

Hello friends.
Please help me out, my Xperia mini pro doesnt power on. I get vibration when press power, but no display. After a few seconds I see the keyboard lights on, but thats all. No boot, no animation And no Led blinking or anything.
I managed to connect trought adb And the logcat show cyanogenmod And stuff like that. Like if the Phone has booted. But I cant receive Phone calls either.
How can I find out if I have a problem with display? Tried a few adb commands with no luck
I dont really know what happened with the phose cause its my son's Phone And he says: I dontknow
When I gave this Phone to my son it had cyanogenmod, rooted And with recovery. But dont know if thats working, as I said, no Led info.
Thank you

If it's an Xperia x10 mini pro (2010) device it may be one of two things: either a broken flex-cable (which connects the phone to the display) or a bad battery.
If it's an Xperia Mini Pro (2011) device, i suggest asking in their forum... (although it may still be one of those two issues)
Its a 2010 device, sorry for not clearify that. the model is u20i, so no internal battery.
As said before, dont know why I cant receive phone calls. I also removed the lock screen if any via adb
you say its the flex cable, how can I know if its booting correctly?
Thank you

Not sure how you can check if it's booting properly, but it's not that hard to figure out if the flex is broken or not, there are tutorials for that on youtube.

Screen turning black and won't respond

after exchanging my phone due to the reboot problem, im encountering a new problem
my screen sometimes turns on by itself, and if i try to operate it at that point, the screen will turn black and nothing is functional except for the soft buttons and the pull down menu, only restart will solve this
sometimes it will also just crash to black even without the screen turning on by itself scenario
does anyone have the same issue? i suspect this is a software problem
I just got the z5 last night, and experienced the same problem this morning. Turns out that if you give the power button a 'double click', the screen comes back on. So this solves the problem reported above.
HOWEVER, there must be a setting (I hope) which we can change, I find it very irritating that as soon as I make a call, the screen goes blank, and you have to double-click the power button to see what is happening. If anyone knows about such a setting, please let us know!
My screen went black about an hour ago.
After Hotspotting for 40ish minutes so I could use my iPhone on the way to work on the train, I tried to check this forum with my Z5C, the back of it was really hot & after a few minutes, the screen went black & the phone was unresponsive for around 20 seconds & then basically unusable once it came back on, for another 20ish seconds, due to lag.

Did you ever find a resolution for this? it is driving me crazy, I've tried factory resets, software repairs via the Sony Companion and this still occurs, sometimes it won't happen for a week then sometimes it happens multiple times in a row even straight after a reboot. The fix that RohitMayor describes does not work on my device. This phone is really terrible compared to the Z3 Compact
I have the same issue. This pb occurs since i have update my phone to 6.0.1...
Any solution ?
