Phone always has a white screen, but seems to work

Hi Forum,
I got a dash with the WM 6.1 from this great forum.
Somehow since yesterday the screen turned completely white
There was no physical impact on the phone what so ever...
When I turn the phone on, the screen is all the time white... but the phone is still working since the alarm is still ringing....
I've tried already the following:
- took the battery out for over 6 hours and tried again
- with and without sim/sd card
- to reset the phone but with no success since I cant see anything (2 softbuttons, powerbutton etc.)
- putting WM 6.5 with no success with the Error 270
- pressing and holding any button
- tipping the jagger for 3 times
- and finally hitting the phone
All these steps didnt use me anything...
I'd be gratefull for any sudgestions
Maybe the screen is just damaged and its not because of the software...
thanks a lot,

Hard-reset will be best option and can be done blind since it's button sequence as known then green key, i knopw that peeps have done it blind and with you spending enough time it will be sorted... The other option is bootloader and flash your stock ROM as won't get an error 270

thanks for the fast reply.
ok about the hard reset.
I hold both buttons beside green and red button then while holding i turn on the phone (power button more then 3 sec.) after it turned on i let go of the buttons and press the green button (I pressed it a several times). What after that?? will everything happen automatically??
if yes then the hard reset wont help since its still white...
unfortunately I dont have the original ROM anymore (WM5).
Do you know where I can get it??

Ok I guess I managed to hard reset this thing.
Unfortunately with no success
can anyone help?
will the problem be gone if I change the display?

Can you sync with your PC? That's something that you haven't state in your original post.

From what you have posted in the first post, looks to me like your phone has suffered water/moisture damage. Classic white screen, nothing shows, display turns off after default timeout seconds, phone functions smoothly. For this to occur, you dont have to dunk the phone in water, phone in pocket when exposed to light rain, snow will do it.
If this is the case, the first thing you can do to salvage the phone is to remove the battery, otherwise the charge will short circuit more, leading to irreparable damage.
Second thing, try and keep it open for 24 hours or more and try ONCE more, just once, if the moisture has been evaporated. If not, remove battery again.
Next you will need to find a service center where they will dismantle the phone and physically air dry the PCB, and hopefully if it hasnt already shorted, it will come back to life.
The cost for this could vary from minimal to astronomical, depending upon which country you are in.
Do not take my words for granted, do a google for phone water damage, find out if those are your exact symptoms.
All the best.

yes I can. I already saved the contact list The phone is perfectly working beside the white display...
@ ccpraveen
I really dont think thats the case. Since I was sleeping on the couch, the phone's alarm went of like at 11 and it was all ok, then 30 min later the screen was all white
And the night before I left the phone at home...
Bringing the phone to some service center is out of question, since I live in Germany... If possible, I'd have to repair it my self...
By the way the Display time out works too... Somehow I got the feeling that it wouldnt use me anything to change the display

please, can no one help

install this on your computer http://www.mymobiler.com/
it will silently install on your s620 when it syncs with activesync and you will be able to view your screen from your computer monitor
if everything works buy a new lcd from ebay and replace it because its probably broken

My impression is that you have a hardware problem, maybe your screen has something loose. If you state that you will fix it by yourself, you can read the sticky on how to take apart your dash.

There are also power management settings that will turn the display white, however if it is white all the time, then it's probably hardware. Loose connections does sound possible. I'd check that first

You can try the following:
*- COMPLETELY disassemble your phone.
*- Take the PCBs apart on a table or something.
Then... take an hairdryer!!!
You have to dry your PCBs: take a PCB in your hand and do the work.
Be aware of not using TOO HOT air, or you'll melt all.
If it doesn't work, try to dry your LCD.
Doesn't work?
Okay, then the only 2 possible fixes are:
*- Replace the LCD Flex Cable if not integrated in the LCD.
*- Replace the LCD.
Hope that you'll get your phone fixed and running

[Q] Cracked Screen, HELP!!!

Hello everyone i need some help with my E4G touch. over the weekend i had my phone in my pocket and some way or another my keys cracked my screen. My screen is completely black i can't see anything, but the phone still turns on and i can also receive calls, text's etc... I want to retrieve all the Data that's on my phone, like my pictures, text's and some documents. when i connect it to the PC Samsung Kies tells me to reconnect the device. It stays doing this over and over and i cant get access to the information i need. My phone is also rooted. is there any way for me to retrieve my Data?
Thanks in advance for the help

I'd try these folks http://mobiletechvideos.mybigcommerce.com/ they do stuff like this.

Bump!!!!!!

Are you rooted? May need that? Idk I'm always rooted, lol. Sorry bout the phone. I will recommend that you use the adb pull tool. I'm not sure of the texts unless you had prior backups which you will get with pulling / not sure it will be pics in a dcim folder /mnt/sdcard/DCIM
Via OG Epic 4g Cm9 & NYGiants 2012 Champions!!!!!

If you are daring enough, i would suggest that you replace your screen/digitizer. i had a similar issue - i broke my screen, it wouldnt show anything but the notification light still worked and the capacitive buttons still lit up when the device turned on, so i knew everything was still working except the screen.
i bought a screen/digitizer off ebay for $65 shipped, replaced it myself. now everything is working perfectly, just as it had before. its something you must be careful when tackling, but its not impossible at all.
reference this if you do take my advice:

if you have any questions pm me as i might not check this thread again

[Q] inc 2 with dead screen

So i recently got a free upgrade to a inc 2 by turning my og inc in under warranty for a blow speaker (for the third time) and i naturally rooted it and installed a nice miui rom. Now about a month later im out of town for work and the screen has died. The phone is still operational, but the screen is black.
I am wondering if this could possibly a firmware issue? i have tried pulling the battery and booting into recovery but the screen is 100% useless. the touchscreen still seems to work, i can unlock it and answer calls ect...
My hunch is that its a hardware problem, but i'd like to try and flash it back to stock if possible to eliminate the possibility of a rom issue.
Does anyone know a way to flash a rom onto it without the use of the screen?
Can i use the HTC sync tool to set it back to stock like i could with the OG incredible?
Any help is much appreciated, i'm pretty desperate here.

if it was me, I'd flash it back to stock using a ruu file, then do a warranty claim, cause then if it's a firmware/software issue the ruu will fix it. There's a thread somewhere around that has instructions to do that, give me a minute...
Edit -found it! Here ya go- http://rootzwiki.com/topic/1579-how-to-restore-to-stock-from-alpharevx-incredible-2-vivow-only/page__st__53
Sent from my Incredible 2 using xda premium

ok, so my new issue is that if i flash the ruu, and the screen still doesn't work, i'll be stuck at the setup wizard right? then i won't even be able to use google voice to make calls from my laptop. i guess ill have to wait till i get home, this would be so much easier if my pos nextel work phone had service out here in wyoming.

Yea, that's a tough one, I definitely wouldn't flash an RUU for the exact reason you bring up.
One option, although it isn't without it's own challenges, would be to try to install a VNC server on your phone, so you could then connect to and use it through a desktop computer. You could probably install it easy enough through the Android Market web site. Here's one: https://play.google.com/store/apps/details?id=org.onaips.vnc
If you download the Android SDK (http://developer.android.com/sdk/index.html), connect your phone to your computer, open a command prompt and run ddms, it'll bring up the Dalvic Debug Monitor. Here, you can go to Device>Screen Capture and it'll bring up a window showing the screen of your phone. There's a refresh button which will refresh the screenshot. It'll be a little hit or miss, but you should be able to reference the screenshot to tap on your blank screen to open the VNC app, hit the start server button, and then see what IP/port it's listening on.
Once you get the VNC server running and connect, you should be able to use the phone fairly easily, although if the screen is dead even during boot (no initial boot screen, no display in h-boot) it would seem like a hardware problem and there's probably not much you can do about it.

Where is it indicating that it's the wrong device if you have no screen?

I ran into a similar problem with black screen over the weekend.
However my phone was not rooted.
This is how it happened.
I was using my phone then I saw the screen flicker once or twice, then it went black.
I pulled out the battery and powered up again.
The phone vibrated, and after a while the four bottom buttons light up.
The volume keys work and I could receive incoming calls, but the screen just stays black.
One thing to note is that my pocket was a little wet before I pulled out the phone to use.
Also that I did use my phone for a good 5-10 mins before it went black.
What I am trying to determine is if it is a software issue or hardware.
Are the bottom button lights separate from LCD screen, so that even if they light up it could still mean LCD is bad?
Any help would be appreciated, thanks!

[Q] Need to get pictures out of broken screen s3

i broke the screen of my galaxy s3, i reported lost since warranty didn't cover broken screen. im trying to get my picture and if possible my contacts.
phone is not rooted. and usb debugging is off. i tried using Samsung galaxy s3 toolkit v 7.0.0.0 and going to the option back up and restore your device.but usb debugging is off. any help will be appreciated.

Just throwing the idea out here for anyone who has used it before or knows anything about it... HDMI-out?
I've personally never used it, but if it were possible to somehow HDMI-out and view the screen externally; say you were to display your screen onto your TV or PC monitor, while navigating on the touchscreen [assuming it isnt completely busted] you could enable settings to debug/adb and such...
I could be completely off-base with this one though.

Awesome. Glad you got your stuff back

Cracked screen, visible but doesn't respond to touch.

Hey guys, I am in dire need of help... I have a family member with an LG Optimus G and the screen has been cracked on it, unfortunately the device is full of baby photos. The device was left in charge only mode and we can't seem to access media sync or anything like that. The strange part was that we also tried getting it into bootloader but it REFUSES to do so. We can see the screen, it just doesn't respond to touch. Any ideas? It seems like most data recovery programs require usb debugging to be turned on and then we were gonna go the adb pull route but like I said... It won't go into bootloader. Phone boots fine though.
It seems the device will only show up as "Unknown device" as well.
