HELP desire z screen wont turn on

Hi everyone, I got my desireZ back in November and it has been working perfect ever since, i have it rooted using VISIONary and everything was perfect until today. The phone was in my pocket and i was lsning to music, i looked at my phone and all i saw was a white line going from the top of the screen to the bottom, i pressed the power button to turn of the screen, then i pressed it again and now all I see is a black screen with the back light on.
I have tried to soft reset the phone, took out the battery sim card and left the phone for a while, came back turned it on and still the same thing black screen with the back light on... The touch screen works fine i still hear the phone receiving txt msges and emails, i can even receive phone calls, and answer them by sliding my finger across the screen like usual.
I am trying to do a hard reset of the phone but i can't do that cause even when i turn on the phone while holding the volume down key i still dont see anything on the screen
any help would be appreciated.
EDIT - after trying to open the keyboard a couple of times, now the screen turns on white... when i press the power button to turn of the screen and turn it back i see a fading effect where the screen slowly turn on from left to right (fades from black to white) and then stays white till i press the power button again....
Since i have rooted my phone, i dont belive i can take it to bell to fix it the way it is... and since i can't see the screen to perform a hard reset to remove the root (i dont have s-off) ... does anyone know of another method for doing this? maybe with connecting to a computer?

There is another thread on the forums about someone having the same issue. I believe there is a solution using adb on your PC to connect to the phone.
Not sure how 'tight' your service provider is, but if the screen is dead, and you are still under your warranty period, they may simply swap the device for you after doing some 'basic' tests and dump it into the bucket that goes back to the factory for refurb. The fact that it is rooted won't be discovered until much later, if ever, so it may not be an issue.
Good luck!

Any idea on the location of this thread, can't find it anywhere.
I am suffering the exact symptoms as the OP with my Desire Z which is rooted with visionary rom flashed - I would really like to know how to use adb to resolve this !

strange problem

Hello everybody,
first I have to say that I´m from germany and I´m sorry for bad english .
But no my problem:
Yesterday I tried out my new Nexus 7, everything worked fine, no problems...
Than I had the bad idea, too restart my device.
So I turned it of, trying to restart it -and yes you´re right- it doesn`t turn on again.
First I checked out the internet for information and I found out I´m not the only one.
I also found out that I don´t have the same problems as the most, cause I tried to start the device with pressing on 40 seconds or on+volume down....and all these tricks.
The next step I was trying, was too open the nexus backcover and disconnect the accu but the result was the same :
The Nexus doesn´t start!
But the funniest thing is that my PC regionise the Nexus and I can read/write on the internal storage.
So what do you mean ?
I dont want too send it back(cause it´s a bit of complicated - I had bought it in Ebay.de from somebody out of austria ) ...
Thanks for your help. I hope my Text isn´t too bad at all.
Best regards
Phil
It sounds like your screen has failed. The PC would not see your internal storage if it were not on. Maybe you could use one of the toolkits to try and restore a factory image in case it is operating system related.

Thank you for the quick response .
Do you think I can fix the screen by myself? Maybe it´s an connection problem and not the screen itself ? The Nexus 7 Toolkit I tried out a little bit, but its not easy to do anything with it, because at some tasks I have to do some input by the Nexus and I can`t see anything.
Another thing is why did the display failed by turning on again and not when it´s on ?
I hope I can fix it today :crying: I just dont want to stare at it, instead of playing with it.
Phil
Hold the power button for a full 30-35 seconds. Make sure it's plugged in, just in case the battery may have drained to much.
Should restart.
Nexus is running. I cant believe. )))
Thanks for the tip tootbrain, but I tried this out over and over again without any result.
Then I want To show my father the problem. I pressed the button just to demonstrate, but then it works.
Another thing was, first the screen had very low brightness (cant set it up with the brightness settings ) and after one hour suddenly it had became bright. And i didnt do anything.

maybe when you disconnected and reconnected the screen you may have fixed a previously broken connection, or even given it a little power jolt that got it working again? from your description of brightness staying low then slowly goin up to normal use....maybe you just breathed some life into it.:good:

Samsung Galaxy S3 - Touch Screen Not Working

Hi
Yesterday, I broke my samsung galaxy s3 screen
Now all i get is a black screen. And with no way to access anything that is on the itnernal memory on my phone.
When I plug my phone, I usually have to bring down the menu bar, and click the mount option. However, as the phones touch screen doesnt work, and the screen is just black, I dont know how to back up my data.
Does anyone know if there is anyway of backing up my phone?
Thanks

You could try to use Kies to backup some data i guess.
Wrong section, post in QA
I think someone had posted a guide to navigating your directory blind. Have no idea where it is, but do some googling, it should pop up! Good luck.. and as mentioned please try to post future questions in Q&A!
<sent from my quad-core S3>
Just plug in to computer and save files from internal memory. If you want to do a backup, boot into recovery and then use volume buttons. Can't remember the sequence. Just Google image a screen shots of CWM.

Help with broken camera

Hi!, I have been having problems with my phone camera for a whyle (2 years aprox). Since I started using lolipop and marshmallow roms the camera hasn't been working fine. Actually it doesn't even work. I would post some images but this is my first post and XDA doesn't let me, so i will describe it the best I can. When I open the camera app, all I see is white, after a while some pink dots start to appear. This dots multiply all over the screen and thats all I get. If I zoom in this pink dots gets bigger, and look like pixels, like it's some sort of digital filter, and not what the camera is capturing. If I wait long enough, and point the camera into a light, the image gets clearer and it starts to show something. I am now using Dirty Unicorns 10.6. It's a D806 model, but inside the phone, it says it's a D805. I have always used D802 roms.
It looks like is a hardware issue, but everytime I go back to KK stock, this problem stops and the camera works just fine, then when I flash a custom rom after some weeks, this problem starts again. Also I have searched a lot and it seems like no one has this problem. If i try to film a video, the app crashes and it saw "it couldn't conect to the camera" but in the normal mode if I touch the screen, I can see the lens moving, like it's adjusting it's focus
Do you have any idea of what could it be?. I dont know if this is important but I have bricked my phone several times, to the point where one time even the download mode was broken, and when I pluged the phone into the computer, windows detected like 60 particions. I fixed this via pushing some files into the phone using ubuntu, and then doing the same thing in windows with a tool I found here in XDA.
Thanks, and sorry if my english is not the best, is not my native language.
