[Q] Xperia mini pro screen remains black - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

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!

Erratic touch screen? Please help!

I have a T-Mobile Pocket Phone Edition,
It's had a rough life but as kept going for over 3 years now.
For the last year I would have to realign the screen 2 or 3
times a week but over the last few months it keeps getting worse.
Sometimes the screen won't respond to anything anywhere,
then after I tap it a few times boom works fine.
Sometimes I'll tap on the “Ok” and the “Start menu” will activate.
Sometimes drawing a line up the center of the screen will end up
shooting all over the screen.
And sometime it will work perfectly!
I thought the problems were to erratic to be hardware so
I hard set after awhile it started again,
So I hard set and installed a different ROM after a coupe hours
the problem was back.
Also sometimes the align program will get stuck in a
loop that doesn't end.
I've searched but can't find an answer? Anyone have an idea?
I've already taken it a part once but couldn't see how to get
any further after I toke the back panel off? Please help!
WOW nobody? So no one was heard of this problem before?
Can anyone direct me to directions on taking apart the Wallaby?
Thanks <><
It's a problem with touch screen. You should check (and fix) it.
Maybe it is necessary to press well screen to the motherboard. (Sorry my english).
Ok, Can you tell me where that connection is?
Thanks
Toke everything apart, found the connection, cleaned everything (w/ screen wipe)
put it all back together. Still have the touch problem and now the backlight won't work!
I've found if I press the unit in my hand the touch panel works right,
I don't think it's a lose connection to the main board so I think it must be
one on the main board.
If anybody thinks they want it for parts let me know! :?

is my Digitizer broken? :(

Hey guys!
something happaned to me 2 days ago.
everything worked great, and suddenly the HD screen wont work properly.
the left side of the screen sometimes reacts defferent when i press the left side screen.
for example - i press the Start on the left, and it reacts on the right!, if i press the right side it works good!
ive done few HR with changing the ROM few times too, the problem is still there...
when i do screen align - the buttons are getting pressed ok, when i start to use the phone its getting crazy, i have to press the left side at the end of the screen so it can react on the middle...
im getting crazy cuz everything worked great 2 days ago...
the picture on the screen is perfect - no defects except the touch.
also when i press the left side of the screen' lets say on the TF3D Tabs and living the Stylus on one Tab, its shaking a bit like im playing with it...
all the 4 HARD BUTTONS at the buttom doesnt work properly either...
thank you all...
BTW something happaned to alot of people? i can see alot of messages about those things..
* also one more thing..
im using my phone as a Modem for 4 months already, can it be one of the resons to make the Digitizer go crazy? the heat? cuz its get hot as modem...
Hey.
thanks for the answer.
but my qustion is if it really is my Digitizer...?
yes i got the same problem, send it to my reseller and got it repaired.
In a few hours i go to the poststation and get my HD back
greetz
yeah my seller lives at the other side of the country lol...
thanks guys for the help.
=]
OK
something doesnt make any sense!
ive done another HR- another ALIGN SCREEN' and suddnley the screen works perfect! no stuttering, no jumping from one tub to another!
how can that be???
ive pressed the screen hard enough to see if the problem comes back! and it didnt...
how can that make any sense?
Damaged Digitizer will do that?
Hey!
thanks for the answer, but i live far away...in Israel \=
the main problem i have on the screen, is the OILY LIQUID under the screen! that what causes the problems, now my HD wont work at all, or maybe sometimes when it wants to...
now i have to send it for repair...and hope it will be ok
I'm out of luck,
One year ago, in the beginning of August, I had the Digitizer problem...
After a year passed, I begun to noticed again a small oil liquid on the LCD!!!
I still don't notice any problem with the touch, but it's a matter of time...
I can't believe it!!! 99% for sure that I have to send my phone to repair again and almost exactly one year after the same problem!!!

[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.
Sent from my Transformer Pad TF300T using xda app-developers app
I have also the same problem from some days
tried to reset all with flashtool with no luck
the problem is also during kernel loading,tried different kernel,logo and cw doesn't appear 90%times
if someone is able to read in logcat file I have attached one here
thanks for any help
me also
i also have the same problem with my xperia x10
bad news for all of us.....

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?

Ghost Touches on Sony Xperia Z2

I have a sony Xperia z2. Bought it a year ago, everything worked fine for 11 months. One day i was using my phone and suddenly the screen went haywire. On further inquiring i realized it suffers from ghost toughes. I enabled the show touches option to give me the exact idea where the ghost touches appear on screen. There's something strange about it, only 2 ghost touches appear on the top right side of the screen, BUT WHEN I SWITCH OFF MY SCREEN AND SWITCH IT BACK ON THE SCREEN BECOMES RESPONSIVE FOR 5-6 SECONDS. Then ghost touches appear again. I have TRIED everything, formated, restarted, changed screen guard, cleaned the screen, changed the charger, did a software repair procedure suggested by sony. I really really really need help, I'd really appreciate it if someone tells me how to fix this issu. Thank you.

Touch stopped working in a pocket

Hi all, I was a member here for a dozen of years, but cant recover my acc because Iam not using gmail anymore ; )
Back to question: I used z5c because lineage, after windows phones, and all worked fine. Yesterday, I placed phone in my front jeans pocket, had full hands of some bags. Then, I sat in car, took phone out and touch didnt worked. No any physical problem visible. Phone itself looks as before - mint condition. I tried to reboot several times, went into twrp... nothing happened. touch was unresponsive.
I left it turned off for, maybe 6 hours, then I turned phone on and touch worked! But, I noticed that it is very sensitive - really soft touch was enought to perform action. I took soft cloth to clean display and turned only display off. When I turned it on, after few seconds touch stopped working again!
Touch worked fine before, same during this short period of time when worked again. Never noticed any problem with it.
Any idea why this happened and what I can do?
UPDATE:
I left phone turned off and put it on charger. He had 20% bat. I took him at 99% turned on and touch working again!
also, I can bet, I am 100% sure, that yesterday, while using otg mouse, I didnt saw in settings > display > high touch sensitivity option even I tried to find it several times. I thought that option, for gloves is turned on. And now I went again there, and that option is present! Hows that... And it is turned off.
Anyone have idea what to do with touch? Why is that happening?
