Blank Screen - Mi 3 Q&A, Help & Troubleshooting

I'm having this problem for almost a year now. The problem is with the screen. After a week or so once every month my mi3 goes Blank without any preceeding problems at all. The on screen buttons are on and the phone is also on that I can confirm by using the volume keys and the power key.
Sometimes the phone screen turns on automatically after few days sometimes not. Then I have no other option but to use fastboot.
I would like to add that my screen got broke and got replaced from service Centre and since then this problem started happening. But i personally don't think this has anything to do with it.
It's nearly been an year now and I have tried all possible solution at all leading forums. I think there is something to do with proximity sensor but tried all solution for that too.
Any help would be acknowledged.

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.

Soft keys not working :(

Hi guys,,
my motorola milestone's softkeys have stopped working..
back, home, menu and search button,,
i tried to factor reset the phone,, bboth soft and hard but still no luck..
let me tell what happened..
i was watching some movies when it happened..
i was able to send a message before it occrred..
then i placed it on top of my laptop..
after some 15 mins.. i heard some weird noise from it..
it seemed to be possessed.. vibrations is audible.. then i checked the phone... the touched screen is not working at first.. so i turned the mobile off..
then i turned it back on.. the touch screen works fine... responsive as it always..but when i press the soft keys it stopped working
any idea how this happned??
is there any way to fix this???
ideas would be greatly appreciated
Button savior / virtual button bar.
Your digitizer is dieing/dying.
Or maybe another problem. When I replaced mine, the first I got it was like yours, my buttons didn't work so I got around with button savior. The second one i got work flawless.
Good luck.

thanks for the reps dude... really appreciate it..
i think its the digitizer... but i think its kinda weird that the screen works flawlesly.. its just that the softkeys recognize the touch its just the area whose reacting is on the top of the soft keys.. but the entire screen is really responsive..
it's the digitizer
on my milestone it started with the back button not responding and yesterday it died completely. at least the ghost touches are almost gone but now the whole display is not responding. good thing we have a hardware keyboard
Same problem, touching the button area and the digitizer recognized as touching the upper area.
Thanks.
I was suspecting the connector as the digitizer was new, or it supposed to be, but now I know.

Touch Screen unresponsive!

Has anyone had issues with their Z3 compact screen becoming unresponsive to touches? This happened to me last night even after hard shutdown via power button + volume up key.
My phone is encrypted so after restarting, I was stuck at the code unlock screen but the touch screen was completely unresponsive. After a few more hard shutdowns, a few hours off and alot of cursing, the touch screen finally started working again as if nothing was wrong.
Any ideas guys? I don't want to send this phone in if this was a one time thing, but I'm afraid it won't be the only time...
I guess I'm the only case of this happening?

It can occur for lots of reasons
This can be only software lag instead of touch panel problem.
and even 3rd party app can freeze your phone like this.
anyway the possible solution and way to understand if it s software or hardware problem is to repair firmware by PC companion
:good:

The reason I don't think its software related is because after the reboot my phone goes into the device encryption unlock menu right away. This menu theoretically should have little to no software loaded at this point, yet it still didn't response to touch. Now, I did recently downgrade from the latest UK ROM to the next available U.S. ROM. Not sure if that may have affected anything...
No more problems yet though...

Was the phone wet? Water can mess with the capacitive screen but shouldn't still be a factor after drying it with a rag. I'm assuming you realized this already, but doesn't hurt to double check.

Screen is not the issue… its the system

My Z3 do this too.. i dont know what to do
Same here. Happend 5 minutes ago and since no response from the phone -.-"
I hope it settles itself again.
Edit:
Now it works again. Strange behavior
I just returned my Z3c because of a touch screen malfunction. But in my case, it wasn't unresponsive, it just went nuts. It located taps at totally different spots from where I was touching, so typing, scrolling, etc. just was impossible. Luckily, this state only lasted for a couple of seconds up to a minute max, but occurred several times a day. Phone now exchanged for the "big" Z3 (due to arrive tomorrow), hope it hasn't the same issues.
I have found the reason my phone was unresponsive. I disabled some apps through adb, one of them seems to have caused the issue (dunno which though).
So I just restored the phone using the pc companion and since then no unresponsive touch screen.

Z3 Compact top half of touch screen not working
The top half of the screen of my Z3 Compact doesn't register any touches anymore. The bottom half is OK.
The phone wasn't dropped or anything. I did a repair with PC Companion and nothing, still the same....
Sigh!
hello, well the same thing is happened to me but my phon is z3 dual, this happened just before hour ago
Any solutions ..
I've just bought it about 2 weeks ago
I have the same problem, the touch is not responding and I can't use the phone since yesterday.
did reset by buttons and also by that yellow reset button and still nothing, it powers on but I am stuck when it asks me to enter the PIN code, because the touch is not working.
Anyone got a solution for that?
Which apps you have disabled on adb and say cause that issue?
Same trouble over here. Experimenting this unresponsive touch panel since today, several hours without working at all. I just blocked some boatware apps, but this should not affect touch panel, right?
Just restored the whole phone using official from Sony PC Companion software. It remains the same trouble with touch panel.
Today, in house, we put the phone under tap water just a blink. Do you think this could have damaged the device, though is water resistant? Do you know where are the humidity sensors, that could have change? Thank you for helping!
