i have a SE mini ST15i. i got same problem. Help please!
tks
I had my unit for two weeks now and so far i've never encountered this problem even though i've been playing a lot of games for more than 30 minutes.
What color and build number are your mini's? You check it out at the back of the unit after you've removed the battery.
mine is 11W31 Mini ST15i Black
Mine got the problem after 2 weeks, mine is 11W29 Mini ST15i Black
i got the same problem too... its really annoying... hope someone wud come out with a solution,,...
So, during the first two weeks your phone was working perfectly. And only after having it more than two weeks then the problem starts?
I had my unit 2 weeks and 2 days now. and have not encountered the back menu malfunction.
Yup i given back to service center and got back with in a day now i was testing it for 3 days since no problem so lets c how it goes later after some days
it may be the overheat problem..... after charging for a couple of hours it happens..
if u dont experience it,, u r lucky...
have a look at this link.. http://talk.sonyericsson.com/message/111285#111285
Since I bought the unit I've been charging it overnight before I sleep and so far it doesn't overheat. I've read it in the manual that it was alright to charge it as often as you like.
It seems that the build of the touch pad of this model is defective, just like with their unit the G900 which also had a lot of complaints.

[Q] Xperia mini pro screen remains black

Hellow everybody! 4 days ago I got the screen I ordered from ebay and I have a big problem! I installed the screen on the phone, and the phone was booting up, the touch screen worked I could sense the lock screen when I touched it but nothing! Also the phone was burning! after noumerous tries , the screen finally worked the next day! But one day after , it had the same problem!Now the screen is black since two days ago! Any help! I tried repairing with pc companion, but the screen still remains black!!
Since you installed it yourself, you maybe made a mistake during install, something wrong got connected or something.
You said, that phone heated up. Some connections could have melted or even some chips.
xperia mini pro
The phone worked for a day before repairing. And it didnt worked for two days berfore repair, after it had worked!!
Does it work now or not?
Yes it works , the touch screen works i can feel it by sliding the lock button.
But it remains black, i heard sound about the battery. so the phone works but the screen remains black.
Seems like connection issue between mainboard and the screen. You mentioned getting warm - could have been too hot for the connections.

No I've trying installing the screen many times , but the heat was coming from a single part of the motherboard , i opened the phoned and touched it! It was burnig hot! Now there is no heat , the phone boots up, i can sense the lock sliding when I move it (vibration) but i cant see anything!!! It worked for day perfect! The first morning , heated for some time , but it work after ten minutes for a whole day with no problem! the next day i went to the cafe of the village and connected to the internet by wi-fi connection, when I left, the problem started again ! And the phone is working , as I mentioned before, but the screen isn't viewing anything!

[Q] Xperia Ray - Black screen after stand by...

Hi, first sorry for my english, I hope that it will be clear enough to understand my problem...
My Xperia Ray, updated to ICS, display a black screen (with backlight) when waking up after a stand by. I have to wait for undertermined time to have something on the screen, sometimes I remove the battery and boot the phone to be able to use it.
I updated it to last 4.0.4 ICS thinking it will resolve the issue, but it has not.
I can still use the phone when connected to MyPhone Explorer with the phone keypad, while the mobile's screen is black the MPE windows shows me the "normal" mobile screen. Everythings else works normally.
I'm afraid to give it to customer service, it was a SFR branded phone and I flashed it with a generic firmware.
Locked bootloader, sfr gave me unlock code for sim cards, lost my root with last upadte too.
Any help ?
Did it also occur on Gingerbread firmware?
Didn't try with GB, it happened when on ICS .562, SEUS update to .431 didn't fix the problem.
I have the same problem with my Xperia Ray.
It already happened on GB and now also on ICS.
The screen stays black if you try to wake it up after standby (doesn't matter if power button or home button ).
This happens around 80% of the time.
The only things that help are: Waiting a few minutes, taking out the battery, or hitting the power button like crazy and eventually the screen will show up again after around 10 times on and off.
I brought my phone to the service center of the shop 3 times and every time they tell me they won't repair or switch it because the hardware looked fine in their opinion (they don't switch it on there, the one time I showed them the switched on phone with the error, they told me they could see the problem but as long as nothing inside is broken 'it's not their problem' . I told my lawyer and now he is trying to get me a replace phone.
The problem even comes right after you factory reset so I don't think it's an app.
It happens without the sd card in.
I had an different homescreen launcher installed around the time it first happened, but I removed it and it still happened and I factory reseted and it still happened. So I think it has nothing to do with that?
I tried software repair with the SE Update Service and it told me everything was alright.
Does someone around here have an idea what could be the cause?
I brought it to SFR customer service (here in france) 2 time, the 2 time they just downgrade it to GB, diagnostic was "update problem". They didn't take in consideration what I told them.
One of the shop employee told me that the third time normally they have to replace it by another one. If they don't want to change it I think I'll mess up their shop...
This even happens on Xperia Mini
when ever i try to wake it up by pressing Home button or Power button
it takes about 3-5 seconds to wakeup
it should be instant isn't it?
I also experienced 2 times that even pressing
all the buttons doesn't wakes up the screen
but only back light, then i have to restart the
phone by removing the battery.:crying:
Me too !
I have tha same problem !! I can't take it esay..It's bad thing in my Idea! very disgusting :crying:
I've got the same delays on my Lww, sometimes my phone doesn't wake up at all, and sometimes it takes several seconds. I haven't found any solution for it, but it seems to be a Sony-specific problem.

I turned the sound for messages and phone calls back on. On 'silent' the phone just vibrated.
It hasnt fixed the problem of the black screen completely, but it is happening a lot less for me.
Finally I brought my Xperia Ray to the shop where I got it for the third time.
I bought it 159 Euros in december 2011 (plus Sony gave me 50E back) and they refunded 270 Euro in november 2012 !
Not exactly a refund because I had to choose another mobile, so I took the Xperia T which was 430euro, so I had to pay 160 E for the XT.
Good deal for replacement of a one year old mobile ! Only problem is that I can't unlock the BL.
It is a strange hardware problem since the screen can eventually be turned back on, so maybe it is something in the firmware that is screwed up and doesn't get completely fixed by SUS. If I were you guys I would try this fix: http://forum.xda-developers.com/showthread.php?t=1492805
It may not work, but it is better than throwing your Ray in the trash.
I have the same problem. My phone (xperia ray) after standby or after reboot has black screen with backlight. At first waiting for couple of seconds and trying to wakelock would solve the problem, after few weeks to wake up my phone I needed it to reboot (pulling out the battery). Now I need few reboots to start the device with screen on.
I found workarounds like Llama combined with Nightclock (both from Google Play) for the screen never goes off, but this eats battery and also sometimes the screen would go off. I don't believe its a hardware problem because with this workaround the phone is usable few days (until Llama delay the "events").
Found a way to make a logcat from starting the device. Two are for unsuccessful startups (black screen with backlight) and one for successful (screen on).
I think the problem is in the kernel for not loading drivers, but someone who knows to read logcat will tell us/me for sure. I can't flash new kernel because the phone is with Bootloader locked (Bootloader unlock allowed: NO).
Kernel version is 2.6.32.9-perf
Stock Rom 4.1.B.0.587
rooted
PS. Sorry for my english its not my native language.
Just to add one or two more informations: even with black screen and backlight the phone is usable, like I can answer on calls, it vibrates when I slide to unlock... I also thought the problem is in proximity sensor, but if it was that case the touchscreen would be locked.
If you fully discharge the battery and after switch on,it start normally?

[Q][Help]Xperia Neo V screen doesnt work but phone does

So last year i was using xperia neo v(MT11i) before it fell on the ground and turned off. When i tried to open it the phone was responsive (i could hear the sound while turning on) but the screen remained black. While charging it was still working and the led was on but still screen was black. I dissambled the phone and the lcd display was not broken at all.
I saw online that a new one costs only 10€ so i would like to know whether buying a new one would fic the problem or not. The reason is that lately i want to get started with rooting my devices but i dont want to make a firts try on my new gal s3 neo.
Thanks in advancr
