Problem - no display on my Xperia

I have lost my display on my Xperia phone.
The back light comes on -- but that is it -- NOTHING else.
Has anyone else experienced this and more importantly - fixed it ???
if so, what did you do
What have you tried to fix it? I'd say something like this goes in order;
1. Soft Reset (since you don't have a display, use the reset button next to the battery)
2. Hard Reset (hold both hard buttons while pushing the reset button with the stylus)
3. Call someone, either your carrier or SE.
I have the same issue.
About 2 weeks ago issue started.
Waking from sleep or turning on, backlight lights up, but screen is blank.
This is starting to happen more frequently. Sometimes it will work normally, but more and more it is just staying blank.
Also during normal use, screen will become "garbled." Random bits of the screen move around to other parts.
Even during these problems the phone is functioning normally, can even push the buttons on the touch screen even though they are not being displayed.
I have an x1i, hard-spl. Was previously flashed with TouchX 10.1. When issue started happening, I flashed with a newer itje WM6.5 ROM. Same problem.
Issue of screen being blank also happens when booting to the tri-colour screen.
Any ideas?
I had the same issue screen just refused to display. I sent it back to Sony E for repair. They repaired and returned within 7 days. On the repair bill they stated it was a loose connection.
Interesting, hopefully that's it.
Out of curiousity, what was the repair worth?
Just wondering how much i'm up for if that is the case and I send it back.

Click to expand...
Click to collapse
Yeah.. I know this topic is pretty old, but I exactly have the same problem..
I have the Xperia X1 or about 1 year and a half now, everything was working fine until 2 days ago:
1. If someone calls me or I call them, they don't hear me, but I DO hear them
2. Screen responds, but remains blank (backlight only turns on)
3. Screen shows once in a while, but it pixelates.
I'm thinking of a hardware problem here, anyone knows more about this?
- Tried rebooting > no effect
- Tried soft reset > no effect
In most of all above problems it would be becouse of damaged lcd flex cable. It's not cost too much but you will have to disassemble phone and change it. http://cgi.ebay.co.uk/for-Sony-Eric...ries_MobilePhoneBatteries?hash=item563a472301

[Q] Problem with screen and keyboard

Hello ,
I am having a problem with my Sony Ericsson X1 , my screen the last days is black and i need to press many times the turn off button so i can turn on / off the backlight and work , but today its not working anymore this trick .... ! i took the battery off i put it after a bit time and still the same . Also i had a problem with my keyboard and screen when i put the keyboard down my screen wasnt going down also and was stacking in the normal way like having it close... !
Any1 could give me a hand , maybe any1 knows how much the screen problem will cost?
Thanks a lot.
It's a problem where the ribbon cable that connects the phone (in the keyboard bit) to the screen is worn and then it starts to have problems with the screen. In the end, for me at least, the screen wouldn't turn on at all. I just sent it to sony for a fix, and they said it was free.
That's what your problem sounds like considering the keyboard seems to be related to the screen

Backlight problem after replacement

Hello everyone,
I have got one problem... I broke digitizer of my HTC Desire 500. So I order new one and to be sure, also LCD screen. I replaced, and...
After turning on, everything works fine. Digitizer works properly, screen shows normal picture. But after few minutes - restarts (I don't remember well) backlight of my screen goes down and now it have no backlight at all. I rebooted phone many times, I remounted screen and digitizer to be sure that connections are fine - but no results. I restored factory settings of phone with no effect too. :/
Please help, what happend? What could be the source of problem? I don't want to order new sceen if it could beak too ;/ I read other threats about coil problem in other HTC, but I cannot find any coil in my Desire's motherboard (maybe it is hidden under plate that covers CPU and other parts). I performed tests of light sensor and it works fine. Buttons lights fine too. The problem refers only to LCD screen, and backlight doesn't respond during test.
Anyone help?
same situation
Hello kowal_luki,
I'm just in the same bad situation.
After a bad fall of the phone the screen broke so I ordered a new one for replacing it.
Opening the phone I noticed that also the LCD (and not only the external screen) was broke so had to order also the LCD.
As precaution tried to power-on my device without a complete assembly and everything seemed to be fine, so I decided to glue the LCD to the outer screen (the touch screen) with a LOCA TP-2500 glue.
Then I re-assembled it up: at first the image was a little bit disturbed but the back-light was working; after few second the back-light turned off. I checked the cable, after that the image went perfect but the back-light still dead.
Did you find a solution for this -still not explanable- problem?

Problem with touchscreen

I have some problem with touchsreen. All work fine until I put my device in pocket (or press him). After I take out my device I can't unlock him, and me need turn off screen and turn on him several times, until touchsreen stabilized.
Who have simmilar problem with touchscreen?
same here :/
same here. I can click few times right after I turn on the screen but only for one second.
same here... tried reflashing etc. via *#7353# -> dot mode, I can see that a spot is being "pressed" in the middle of the display and 1,5cm down from the top. And constantly, thus another touch is not possible. Usually after locking the phone and turning the display on again it works for some time. But even in the recovery it doenst work... sometimes... under key test. Randomly the touchscreen is being pressed.
Had no problems until now... always had a screen protector foil on, but even with a new one and without one it doenst work. Did not dropped my phone, neither I have screen cracks etc...
Any suggestions?

[HELP] Black screen on new phone screen

Hi, my screen broke recently and i can't use the tactil touch. I can see the image but can't use. So i decided to buy a LCD + Tactil Touch + Frame. I didn't mount yet the screen. I only disconneted the screen flex and connected the flex of the new screen. But the problem is that is black. The screen seems to turn on but i don't see anything, is all black.
EDIT: I don't know where to ask. I flashed to the stock ROM, 4.2.2 and still black. I updated to the last version Sony has for my phone, 5.1.1 and still is black. I don't know what more to do. Is all working good, even the sounds when i touch the screen. But i can't see anything the screen is working but there's no image. My phone is Xperia Z.
Anyone?
Please help!
Broken screen? Is the old one still working? If yes: return the new and broken display and get a replacement!
The touch("screen") and feedback (vibrate and sound) will work without the lcd! It is a different layer on the screen and is seperatly connected to the mainboard of the cellphone. Also your screen could be working and your backlight not! Turn on the phone and point a bright flashlight on the screen, maybe you will see something, but even then, get a replacement.
