Hi everybody,
I'm new, I've just registered to ask your help. I've already found useful info on xda several times, and I hope to fix this problem too.
After having fallen on the floor, my xperia U screen doesn't work properly anymore. The phone is working, the touch is working, but the sceen is black: when you turn on the phone, the screen is back-enlighted, then turns black and if you touch the power button the screen flashes briefly showing correctly but only for a fraction of second.
What to do? I disassembled the phone to check inside integrity and I didn't found anything clearly wrong. Should I buy another screen and try to change it, or you think that the problem is elsewhere?
I put a link to the video of my xperia U showing the problem:
wwwDOTvideosproutDOTcom/video?id=0d19d245-4079-408a-b5dc-3ca5cb339904
(sorry for putting the link even if I have to wait 10 messages before being allowed, but I think that the video is the best way to show you the problem)
thank you guys
Hmm...theoretically (not necessarily correct but may be), each type of screen has this thin file of wires (it's like a flat-translucent sheet of plastic with parallel black stripes like you often find in monochrome displays) soldered to the board. Maybe that part broke?
I don't know but it's definitely not a software problem.

Thank you for tha answer,
well, I tried to check each internal connection, nothing seems out of its place, how to say... of course I have not an expert point of view
The strange fact is that I would understand if the screen wouldn't show anything ever, but when I press the power/standby button the screen flashes and for a very brief second it works normally....

Welcome. Well, my problem is this, my touch screen not functioning periodically. This means that every once in a short time starts to go crazy, so I tapne something and here start something else. It was as if someone touched me in different places display and use that make my job has become impossible. I downloaded some miracle Touch Visualiser, which showed me that they are in different times, two or even three fingers placed on the screen, although it was not touched ... still turns me something inadvertently, or something not quite touching and I see to highlight that if someone had touched, and turns on .. Does anyone know what fault is it? Why is this happening? What can I do about this? Waiting for quick response and thank you in advance
Remove your screen guard and check if your problem persists.
But i haven't screen guard..... its impossible, because sometimes when it has locked the phone up and for a moment it was good

I am not sure if you understood me previously but I meant scratch guard.
If you don't have one then there could be many reasons for the same, try these steps and see if it helps:
* Check your touchscreen, put this code (*#0*#) => Touch => Run your fingers over the grid of boxes.
* Make a backup of all your data & factory reset your handset.
Do update on the progress.
There is no scratch guard. And what about? Sometimes I can perform this test, but sometimes it is not because the line that I draw, she turns and appears in different places, and sometimes the phone just does not respond to touch, does a black screen and locks up. Already restored to factory settings, did not help...

Try flashing your stock ROM back using to your device, if still doesn't help take your device to the service center as it could be a hardware problem.
I'm Polish, I apologize for my English ok, I'll take it to the site, I have a warranty card. Thank you

Hi guys, i got this used I9003 yesterday and pretty much everything works as expected. its running 2.2.1 (yes, i need to update it), speed is ok... everything but this weird screen malfunction. i read every thread i could find and in almost every case people ended up "deciding" there was a hardware problem.
so, here's what's happening with the screen:
mostly, when i try to start an app it does fine. typing in landscape, fine. swiping through the gallery, browsing... everything fine. the weird part is sometimes the upper part of the screen seems at least partly unresponsive (i mean i need to tap like crazy and it just might respond). it doesn't matter if the screen is in portrait or landscape mode (left or right side up, still the same). it's always the upper part of the screen. the only exception is when typing in portrait mode: then the T, G, and V don't work (when i try to press them, it types either of the keys next to those). i would think it has something to do with that part of the screen (those keys are pretty much alligned), but when i switch to landscape that same part of the screen works just fine... plugging the usb cable makes no difference, neither does the charger: it behaves just the same be it plugged or unplugged. i bet it's just some software issue (i sure hope it is), but i'd still like to hear what you might come up with.
thanks for reading and for your help!

Did you try to calibrate the screen from the settings?
Ok, so i've got some news regarding this.
First: i'm sorry, but i don'know how to report the thread... i'm quite a noob
Now regarding the screen thing... I updated to 2.3.6, and the problem changed: now the part of the screen that's bugging is the middle, both in portrait and landscape mode (from the home hardware key to the top; when i press any point following that line, the input is on either side of it). i found that if i set swipe for writing the keypad works perfectly, even when typing instead of swiping (in landscape, portrait is still messed up), but if i set it to Samsung Keypad it's just as i described in the first comment.
Help please
Also, if you tell me how to report the thread so they can change it, i'll do so happily

Hello,
My phone was waterdamged and stop working completly.
I opened the case and tried to dry it.
after 48 hours of trying various stuff, there is blank screen, but:
1. The phone is booting fine, charging led is working.
2. Using Wondershare-Mobilego, i can backup all the content.
3.The touch interface seems to be working fine, i can see the menus via mobilego duplicate screen (can open the sms box or whatsapp and etc.)
4.Incoming messages keep coming...
I`m so frustrated that i`m using the phone blindly or like remote desktop.
Is it software of hardware fault?
THANKS

After water damage you can only expect hardware damage. to verify - when turning on the device, do you see anything on the screen? you can also reboot to bootloader (via the key combination or via the command adb reboot bootloader (and to reboot back to android use fastboot reboot).
If the bootloader shows nothing, 100% hardware (although there is really no need to check, probably is). You can try changing screen, but the problem could also be in the socket (but I think if it were the socket the phone would not even boot). Worth a try.
Thanks, but no good...still blank screen - no display.
As i mentioned, the phone is functioning well (as seen at duplicate screen).
When you offering to change screen, you mean the lcd touch digitizer only?
I don`t need to buy the screen itself, right?
(I can`t parse outside links yet from ebay)

I mean the LCD itself. If touch is working, the problem is the LCD itself, not the digitizer.
You right, it seems that the touch working fine.
You think that a LCD display screen replacement would be the best try? can you paste a link from ebay please?
Hi,
Recently, while using the WhatsApp i was deleting one mesg.. after deletion, strangely one horizontal black line came up.
Initially i thought its an application issue or might be screen refresh issue.
I rebooted the phone in recovery, cleared cache but it didnt worked.
Then i formatted the SD card, made Phone a factory reset, both from phone settings and from recovery mode... but issue is still there.
I am now clueless... how to remove it.
Any help guys .... how do i remove this black line ???
Do you see this black line
in recovery mode?
during the bootanimation?
on your homescreen?
or just in single apps?
If the line is visible all the time its very likely a hardware issue. LCD panels are usually wired in horizontal lines. So maybe one of this connections is broken...

I saw this line in all the places, start from boot screen showing as GT-I5801, at recovery and all places...
Is it a virus or hw issue..?

Well, this CAN be a virus. But todays malware is more about stealing passwords from your device instead of drawing black lines on your screen. And I don't think it's even possible to draw the black line in recovery and during the GT-I5800 logo.
I'm 99% sure it's a hardware fault. You can take a screenshot with Android and check if the line is in the picture (this would be a GPU issue) or on the exact same place on your device-screen and not in the screenshot (this would be a hardware screen issue).
That's the way these devices show us, they're getting old
Have a nice day :good:

Thanks for providing workaround to find the root cause...
Can you name any tool or method by which i can take a snapshot of screen...?

Doesn't your ROM provide a screenshot utility in the power-menu (pressing power button 2 seconds)?
If not, search the PlayStore for "screenshooter" or similar keywords.
And (just for my own interest :silly, does the screen responds to your finger on the black line. Like when you are scrolling through a list and your finger moves across the black line on the screen, does the screen recognize this as one touch action. Or does it break at this line and start a new touch action right after your finger is on the working part of the screen again?
You can test this by slowly (I mean really slowly) moving a widget on your homescreen over the black line. If the touch input is also broken on the black line, the widget would drop when your finger reach the black line. Else, the touch-part of the screen is working properly (Hope this is somehow understandable :laugh
Situation: Samsung Galaxy J7 Crown. Never messed with. USB Debugging not enabled No special permissions (no ADB). I am able to access the Android Recovery screen. Obviously wipe cache partition didn't help, nor Lacking storage booting. Other than the Recovery and download screen: I get the Power/Restart icons when booted normally. Reset works, but power doesn't turn the phone off. No phone calls, Yes notifications. Camera from lock screen comes on (triple click on home button) and touch screen works.
I've tried to trace out the lock pattern in the hopes its still working outside this specific situation. No indication that it is.
All i want is a few sentimental pictures. Although after an entire day of frustration, finding out that the only thing that works is the camera is kinda funny and ironic.
Ive looked on XDA forums, but I'm having no luck w/ exact situation, although I'm sure someone has been in the same situation or similar enough.
Spent all day looking at options (Odin?) and nothing looks like it would work out for me.
Knowing the camera works, makes me hopeful that a mirror would work? No reaction to lock screen pattern makes me think not.
Additional (maybe irrelevant) info. Shows up on home WiFi while Find My Mobile said it was offline (makes sense with Notifications/no calls)
Any advice? Just point me in the right direction if there is one.
If not i hope you appreciate the Irony here. Thanks
(I used to be not so bad tech support, but haven't been keeping up as of late, and today was a painful reminder. Take pity on me.)
Black Screen Except Camera - Galaxy J7 Crown
Hey there anick22! I was so glad to see a search result with something referencing the camera working, on an otherwise completely black screen! I was super bummed to see that noone had replied to your plea for help with this insane problem!! I hope you found a solution by now!!
My 2 month old Galaxy J7 Crown suddenly went black on me one day, and it didn't happen as a result of a drop, or spill, or any other damage. I don't recall having put any new or different apps on it, recently, either.
The triple click of the Home button does open the camera, and the screen lights right up, perfectly. It takes it's usual beautiful pics, and I'm able to use all of the camera functions. I'm even able to view any photos I took during that particular session, buy not any prior pics, because I'm unable to unlock the phone.
"Hey Google!!" also reacts, and will display the result of any question that I may ask it, but I'm unable to go into the answers, without the ability to unlock my phone.
I have been able to get the phone into safe mode, while attempting to power it off, by pressing the power button, and then tapping on "power off" (although this hasn't worked every time I've tried). While in safe mode, "safe mode" is displayed in the bottom left hand corner, but nothing else appears on the screen.
Upon powering up the phone, all of the normal things happen. It shows "Samsung" and goes on to the blue screen to show the "Trac Fone" logo, but once the phone is booted up, the screen is black!!
PLEASE tell me that you were able to find a solution to this!!! I went and purchased a new Moto G7, (since I had a Droid Turbo 2 in the past, and it was amazing!!), and I'm beyond ready to get back to my J7 Crown!! PLEASE HELP!!
Thanks so much!!!
By the way, I'm a newbie here, as If you couldn't tell!!
