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.

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

[PROBLEM] Died?

Hey guys, I was wondering if somebody would be able to maybe help me diagnose the fault\problem part with my non-working diamond...
Basically I went to a club one night and the place was unbelievably steamy / humid. My phone was working one minute and then the next it wouldnt display anything on the LCD. The backlight was working however.
Since then I havent been able to get an image on the screen although when trying to turn it on, it seems to go through its startup sequence (backlight -> vibration -> beep (i think))
I havent had any power to the phone since a day after it broke (a few weeks ago).
I'd like to get it back working again but dont know exactly what part i would need to replace. I'm fairly competent with electronics .
Any help/advite would be appreciated!

Haha, ok that's odd...
I've plugged it into my pc to get some data files off about an hour ago.. forgot about it and just looked at it now and the screen is displaying!
It is displaying and accepting input although it was flickering at first (like pixel shifting). but i pressed the power button to standby the screen and pressed it again and the display is fine with no flickering ?
Ive moved the phone about and shook it quite hard to see if there's any loose connection but the display still seems fine..
Anybody have any ideas as to what it may be?
I'm not going to deem it as fixed until I know what the problem was/is lol
cheers guys

Ok screen actually keeps flickering nonstop, and sometimes 'fades away' to gray/white/black
comes back after a few seconds though

Looks like a faulty connector?

[Q] Phone works, screen does not yet sometimes it does

Hello
One night I was using the phone without doing anything special , some video watching . Phone went dark, tried to reboot. Blank Screen and the capacitive buttons flash. Left it to charge all night, in the morning it started but after I pressed the lock button blank screen but phone still working and receiving input.
Took the battery and SD card out left it for 30 seconds then started it again, Stuck at LG logo. Repeat , phone started ... Pressed lock button once then again to unlock , screen wouldn't start.
Used LG Mobile Update recovery tool to restore it ... Didn't solve problem. Sometimes it does not even start , just flashes buttons, other times it does without screen and last all works even the screen until first time goes dark , in the last two cases I can use LG On-Screen Phone without trouble, in doing so I installed a proximity sensor test app to see if it was causing my screen to not come back on , the sensor looked fine.
Facts:
1. Two day old Optimus Black p970, worked like a charm until stated problem
2. The app that checked proximity sensor showed the sensor to be free when my hand wasn't on it
3. The warranty laws in my country are idiotic so I would do or buy anything rather than send it so they can give me a new one in 3 months.
4. Tried another battery from another Optimus, fully charged nothing different.
5. Stock rom.
Do any of you fine people have some ideas on how to fix this? Thanks in advance

Hi there...
Sometime ago [1 year and a half or so~] I worked at a cell refurbishing facility [there were samsung, motorola and palm devices from sprint] and that problem you have was quite usual. Blank screen, still the phone is somehow usable like reciving calls...
There's this thing called "flex" which is the connector between board and display and that is what we fix, most of the time not even "fix it" just getting it in the right place...
This happen because of excesive use in those sliding or clamshell devices, in OB could be for overheating, you could try to fix it yourself or pay $20 usd [that's what it cost here]

Would that connector explain the fact that sometimes it doesn't start at all? hmm I am thinking now and I guess if it moves and somehow the phone feels it has not display connected it could fail to start... Anyhow thank you

actually yes, it could be only for the flex [some devices don't start at all when not having display or keyboard if there's any] but since our OB is not sliding nor clamshell type probably was overheating.
you say you have stock rom, well now I'm using CM7 but when I was at stock and after using the phone a few minutes it felt warm and some more minutes [like playing gunbros where you need to use both hands and a lot of movement] it was really hot and had to stop playing for a while.
what I'm trying to say is that because of overheating flex could have moved, but because of overheating too may have move something else, you couldn't belive the huge number of micro-things that reside in the board.
so if it's only the flex, it's an easy task to do, just unplug and plug again, but if it's something else it's quite hard to know just looking at it, you need to do some electric measures and stuff, the recomendation is to take it to a tech center or something

Hi. I Have same issue. Two times when i press power buton, butons flashing and screen still black. Phone not responding. I must remove baterry.

Hi there, got the same problem too with my optimus black. Screen goes flickering, shut down don't do any good, and the phone temperature is kinda hot. But in my case it work after I clean some cache and data in the phone storage through LG OSP. After that, the phone temperature back to normal and the phone screen back to normal also. I believe that in my case the phone is overheated.

Verizon LG G2 Screen Issues... NOT the turn on then off issue

I have recently purchased this phone via swappa and haven't had any issues prior to this and that has been three weeks (other than a light leak).
The issue that is happening is the LCD will not turn on. When the phone is unlocked via knock on or power button you can move your finger over where the lock circle would be and feel the vibrations showing that it does register the touch. Then usually I would just hold the power button till it rebooted and this would sometimes fix the problem, on a side note the boot LG logo and boot animation do not show up during this time simply the lock screen would randomly appear.
That is problem, now on to what I tried to fix it. I have put on an entirely different rom and the problem persists, I have also flashed a different kernel on the stock rom with no avail. I at first thought it could be due to a faulty proximity sensor, but the last time the screen was on I checked it with sensor box. One way I have been able to reproduce the problem is after locking it putting it in my pocket and waiting around five minutes, this then will make it so the LCD does not turn on ( Which makes it seem like it has something to do with deep sleep). Also something I just found since I was actually able to find the power off button, the screen also won't turn on when the phone is off and plugged into the charger (this makes it seem like hardware issue). It seems like as long as I keep the phone from going to deep sleep the LCD will turn back on.
Some of this makes it seem like a software issue other things make it seem like a hardware issue. I just was wondering if anyone had any ideas or if I need to buy a new screen, if the mobo is bad, or if I could fix this with software. Any and all ideas are welcome.
Thank you all in advance.

[Q] Phone is crashing after the call

Hey recently I changed my digitizer in Xperia SP. I opened it up, threw away the old digitizer and sticked the new one. Only the most superficial layer. Everything else remained the same. After that I noticed slightly worse touch sensitivity but I thought it might bea common thing since it isn't the stock digitizer anymore. But after some time phone started to act wierd. Sometimes it becomes unresponsive to any touch, I must reset it with the button from behind. It occurs especially after the phone call. Anyone know why it can happen? Power button works fine, also the volume up/down.
I had the byagusz's cyanogenmod11 and I thought that maybe it is because of the system but I replaced it now with stock rom and the problem is still there.
Is it possible that I didnt connect everything properly ? Should I open the phone again and correct every tape ? Please any help is needed
