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] Touch Screen Problem

Recently I began to notice a problem with my phone. Whenever I have the keyboard slid out the touch screen is almost non-responsive. So over the past few days I've tried observing what the exact problem is and I think it could be the cable/ribbon that connects the touch screen to the keyboard. I'll have to tilt the screen back and forth before it will actually recognize me touching it. And I've noticed when I rub that ribbon it seems to work. There's also a crease in the ribbon where it folds on it when you close it. I believe this is the problem but I'm not sure and I want any advice/tips I can get. If it is the cable can you order a new one and replace it yourself?
Thanks in advance

Any ideas anyone? I cant get it to half work so I can text and stuff but I have to press it hard and it still wont work at times so something somewhere or another is wrong.

Flash the stock ROM and SPL, and do a warranty exchange. This isn't a device you want to open up unless you really know what you're doing and are certain of the issue. If you really want to give it a go, then just buy a non-functioning unit from eBay to use for parts. They can normally be had for less than $40.

Wow, I cant believe that I finally found someone with the same problem as I have.
At first I thought that it was a software issue and I reloaded the software on my device.
The screen responds to presses with the keyboard in, but extended it doesnt respond and only the external keyboard works.
So to type a nice long sms I would have to start it on my display, flick out the keyboard to carry on and then flick it back in before I could press send or anything.
How frustrating.
But I did a test now and flicking the keyboard out and then slowly slowly pushing it back in I can get to a stage where both the external keyboard and screen responds at the same time again.
Definitely a ribbon problem or something.
Only had this phone for a few months now and if it already doing this then I am not feeling too obtimistic about its future.
Well, time to take it in for a warranty repair. I wonder how much greaf I am in for now.
Time to pull out my awesome trusty Artemis out the cuboard.

I had a friend that had this problem with his TP2 which I've successfully repaired. First thing if you want to do it yourself, go to youtube and look for the Rhodium disassembly video (this will help you a lot). It is not difficult to change any parts in the phone provided that you proceed with caution and take the necessary precautions.
If you are afraid or have never opened up a phone to fix parts, then I would suggest to send it to HTC - this would be devastating if you managed to break up the motherboard by mistake or any other parts in the process of fixing the flex cable.

Tripp --
Did you ever find resolution to your problem? Recently my phone started having the same problem, which I originally thought was related to messing up the calibration file when I put loaded xdandroid GBX0A.
However, it sounds like my problem is pretty similar to yours -- touchscreen works fine when the keyboard is closed, but when it is open it only registers on the bottom of the screen -- which is actually useful in some sense because I can still hit the soft keys in the messaging app and such, but not so useful if you want to scroll using the touch screen. If I play around with the z-hinge a bit, sometimes it starts working -- which sounds like the same thing that you described.

Sorry, I just seen your post but I never fixed mine as I went ahead and bought another phone (Evo) but I did research the problem quite extensively and the problem I believe lies in the ribbon that connects the two halves of the phone. If I remember correctly the motherboard is in the side with the keyboard and that's why when it's slide out, the touch screen won't respond correctly. You can find the part online and replace it yourself. I've taken mine apart and it's not that hard but as said, you need the right tools and to be very careful.

Hi guys
I have tried all the above
Last resort is i got sprite backyup to work
BUT HOW THE HELL DO YOU HIT "NEXT" OR "OK" FROM THE KEYBOARD AS SCREEN DOESNT WORK????

[Q] Help - Glide crashes and restarts

I bought a Samsung Glide i927 phone last month in the US, i bought it unlocked as i am from argentine, and i wanted to use it with movistar.
Recently the phone started to crash a lot, by that i mean that the screen starts going white, with horizontal lines and pixels of different colors appearing, then just turn off or restarts itself, only to crash again as soon as it starts an then turns off.
When this happens i try to start the phone and select the shut down option myself to see if the next time it starts it doesnt crash. But sooner or later it happens again.
This problem its happening too often, and not while doing something in particular like running an app or something. Sometimes it crashes just by plugging it to the power adapter, it even shows the white screen with the lines instead of the charging battery image when i charge it while turned off. I have already try to fix it upgrading android or doing a factory reset, but that didnt work.
Anyone have any idea of how to resolve the problem, or if its a hardware malfunction that cant be fixed?
To make things more difficult, as i said earlier im from argentine, and i cant go to AT&T or Samsung to get it fixed or get a replacement. English is not my first language, so please forgive my orthographic mistakes.
Thanks

This really sounds like some hardware problem, but to be safe, learn how to use Odin and use it to revert your phone to completely stock condition (cleaner than factory reset).

I tried to do that, but the first times when Odin try to reboot the phone it just freezes and i have to unplug it. After many tries it finally finished, but the phone keeps freezing and crashing.
The phone even crashes while turned of and conected to the power adapter.
Do you think that with LiteROM 0.9.0, that might fix this issues?

I've got reboots too, try to disable auto brighness
It helps for me

Power button issue
I am having a similar problem. At first, it just happened on rare occasions. However, today, it started doing it repeatedly. The phone was unusable. I did some checking around, and it appears that the power buttons on Samsung phones are prone to sticking. Some people suggest you actually remove the battery and slam the power button against a table. I wasn't going to do that, because I could just see it doing even more damage. What I did instead was firmly tap the power button repeatedly. It seemed to unstick the power button and allow the phone to function again.
Another alternative is to have the power button replaced, but that might be a hassle.

First of all, sorry for my bad english.
I bought it on amazon a few days ago, I have the same problem...
I thing aznemesis is right, because my power buttom is very sensitive, in fact, some times, when I press the button smooth and fast, to turn off the display like, the typical menu appears as if I had pressed the button for much longer period. Which proves your theory. The problem is if I hit the button over a table and the button breaks here in Chile do not exist spares of the terminal

Well, I did. I couldn't stand the desire to do so. After nearly 18 hours, the terminal isn't rebooted again.

The horizontal lines on the screen sound as if it is an overheating issue. What were you doing before your phone shut off? Are you using the factory charger?

cure found
take the battery out...blow on the power button with some compressed gas to get the dust out....then pour a drop of silicone based lubricant on the power button so that most of it gets in the gaps...then hit the power button a few times....haven't had any reboots since then

[Troubleshoot] Screen Not Working (Please Help, Phone getting useless)

I have 2 years old OneX. Everthing was going fine. And suddenly I started to have some yellow spots on the screen at two places. I ignored them. Then problem increased. Now whenever I unlocked the phone my screen used to jump around. Like bottom portion of the display used to come at top etc etc. And their were pink glitches everywhere black colour was supposed to come (i.e. black color appeared pink).
I changed the rom to see if it solved the problem. Now, its getting worse.
Now i cant turn the screen on. I push power button and screen does not show. I get a call and screen does not light up and I randomly push the accept button (I know where accept button comes) to recieve the call. :crying:
The only way to make the screen come alive is by pressing the back of the phone. I push the back few times here and there and voila, screen comes on. But thats not the solution. I tried to locate the exact position where pressing the back makes the screen work. But cant locate it. Location is random.
So should I open my phone to check if there is any faulty cable or what ? Or is my phone dying ? I cant afford a new phone.. :crying:

If you don't have warranty you can open it up. It's already almost not working anyway so what's there to loose ? Maybe it's just a connector which needs a little push....maybe it's the display + digitizer/mainboard.

Phone working but screen black

Hello everyone,
I have since the first time an LG G3 (D855) that I root and that works very well.
Recently I bought a new one from a friend for my girlfriend.
He never root it, he reset it and sent it to me by mail.
At the reception, I turn on the phone and there, I have the LED lights, sound start but nothing on the screen.
It reacts when I put the finger on the screen so the touch sensor works.
I try a restart and battery removal but nothing better.
The screen has no shock but I told myself that perhaps during the trip he took a bad cut.
I hope it's just a miswired table, so I dismounted to check, but still nothing.
ThenI try something, I disconnect my phone too and I swapped motherboards.
And then the screen with my card in it work.
While my screen with the motherboards of the phone I just bought stay blank.
So the screen is not broken, perhaps it was a install problem.
So I use LG Flash Tool to reinstall the original rom (following a tutorial )
Everything goes well and ends without worries.
But that didnt change anything, the screen is still black.
Do you have an idea ?
Thank you in advance for your assistance and sorry for my bad english

I just realized that if I strongly illuminates the screen I can see that it works.
It' like brightness was at zero.
It's not a screen problem because when I plug it to the other motherboard brightness is ok.
Someone had this issue?

Same problem here
So I'm having the same problem at the moment, but this is the 2nd time that this has happened to me. Last time. I fixed it by changing charger. It worked for like 2-3 month and then I switched again and the problem came back. I suggest you try a few charges. It took around a week before it got fixed.
Hope it'll work for you.
BTW it was a Nokia charger

Black screen G2 after some seconds even during boot...

Exactly the same problem on my LG G2.
It often go to black screen, but it's not totally OFF. Touch work, and the screen the same, i noticed using a torch that the brightness when to something like zero, but if i increase the level, it stay dark. Only press power button sometimes come back, but few second later... Dark screen again.
It happens everywhere during boot, in home, in lockscreen, in TWRP.
I tried:
- Change rom
- Flash stock firmware...
- Totally switched off for 2 months
- Detach and reattach the screen
- Test proximity sensor in hidden menu
Nothing worked.
If anyone has an idea...
