[Q] Black screen - Nokia Lumia 900

Hi. I have, ofc, nokia lumia 900, and it was working fine for some time. But then screen decided to go black (first some stripes showed, and rest of the screen kind of faded out, but not all the way, then it went black. Everything else worked, touch, tones etc. Firstly, reset after some time worked, but only shportly, but after 2-3 tries, it didn't work as well. So I sent it to repair, and all they did was reinstall system and it worked again. For some time, maybe 2-3 months. then it went again. But this time service guy replaced screen, and it, again, worked fine. For maybe month. But recently when i lock the phone, i cant wake it up. Again, sounds, touch etc. works, but black screen. Although, this time it works fine while using phone, problem comes after locking phone and leaving it a bit. So reset firstly also worked, works until locking. I downloaded lumia recovery tool, and reverted it to 7.5...also worked after reinstalation, but after I locked it...well, same thing. So, anyway, anyone knows why this happens? Also, was previous screen broken? It worked fine awhile after reset...
Also, with this new screen my navigation keys light is a lot weaker, and works only on back and search, not in the midle... anyone knows what that might be? Screen problem?
And also there is onther issue (of course...). Sound from earpiece is distorted. It's loud enough, but if you turn it up, you cant really understand anything. When turned down, it's ok, but too low to actually hear much. On diagnostics, I can't hear anything when on testing audio loopback on earpiece, and when testing dtmf, sound is distorted again. On speaker and on headpones both work fine...no distortion, mic also fine.
So, any help?
Sorry that my first post is that long, and also for seeking help in first post...but, it is how it is

Wierdest thing happened to my 8525 please help!!!

ok so i searched on the sites for a fading to a white screen problem but it looks like its related to the dpad... my phone was really low on battery last night it kept beeping continuously... so by the time i got to plug it in the screen started to fade to white... now the screen has vslight vertical lines and every time i shut off the phone with the power button and turn it on it comes normal but as soon as u touch the screen it fades to white!!! was this caused by the low battery. i fully charged it but still have the same prob. i tried clearing my storage and that didn't help..what do i do?
white screen
you will need to replace the board for the dpad.
ok thanks. is this the same issue that others are having as well? the wierd thing is half the time it works the other half it doesnt...
I had a similar problem. I had pressed the power button to check the time and screen was white! SR rebooted and after the first splash screen the screen faded to white. I finally founded a product called Pocket Controller http://www.soti.net/ (trial ver works fine) that allowed me to see my phone on my computer. I was then able to backup my data to the storage card. I reflashed the phone and it’s worked fine afterwards.
yeah man thats what happened to me exactly... im reflashing the official wm6 rom now... ill post what happens... thanks

damn it didnt work with me my screen still goes in and out when it chooses to. and it is my dpad b/c it stops working when the screen is gonna go..
Hi,
Try tightening the screw behind the red hang up button on the dpad. There is a component behind there which causes this problem. If tightening doesn't work try loosening. It's all to do with the pressure on the chip. Very odd problem.
Also try squeezing the bottom right hand corner of the phone and SR.
Bonkers solution for a bonkers problem but it certainly fixed one of mine.
Good luck!
yes, the screw tightening/unloosing thing works for me. same thing happened when i dropped my unit. i even completely dismantled it (managed to fix the microsd card spring). something loose with the connections.
niec guys thanks... i will try the tightening and loosening the screw... i tried holding down the bottom right and SR didn't work but thanks anway... i guess i have to buy a screw driver to open this thing up... god i remember when i had to take apart my mpx 220 im getting flashbacks!!!
Had exactly the same problem but mine was due to an phone shop employee dropping it. It would do exactly the same as yours. Sometimes it would work fine and once when I reflashed it the problem went away for a few days but if came back.
I used to control it using Soti pocket controller but them migrated to Net Support as that allowed me to control over wifi. In the end had to get it replaced.

Help my phone is dying!!!

I got my hermes from my friend, (HTC X01HT), she didnt want it because she dropped it and the ringer didnt work. it had only gotten unplugged, so i opened it, plugged it in, and had an awesome phone.
I dont think this is normal, but from the time she gave it to me, the screen made an awful highpitched ringing noise, (very uni-directional, it was weird).
Anyways...
now, the screen is just white. for a little while i could get the screen back, just by opening and closing the slider and hitting the power button a couple times.
Sometimes the today would display, then it would jarble up a little bit then fade to white, but i cant even get it to do that anymore.
Anyone else seen this issue? i'd hate to get rid of a perfectly awesome phone.
Thanks!
(also, if someone could post a picture of the device locked screen, where you have to enter a PIN to use the phone, that would be great, im trying to get into the phone with activesync, but its locked, and i dont know where to push the buttons.)
thanks!

Looks like the screen is unplugged, really. Maybe you need to disassemble further, like http://www.pdacenter.ru/razborka/razbor_hermes/ shows?
keep in mind, it worked fine for almost three weeks before the screen issue started... but i will try that when i get my hands on a small flathead again.
There's a whitescreen & D-Pad failure issue that can be caused by many things, including DROPPING the phone.
I wrote a guide about it which seems to be quite successful for many people.
http://forum.xda-developers.com/showthread.php?t=321163
so after trying a hard-reset, (which somehow displayed on teh screen), and clicking no, i was able to get the screen back... only this time with the moved screen problem, wrapping around at the top about 1mm.... and the buttons didnt work.
i tried your guide, but now im stuck at the white screen again... :/

On my note 2, the sound sometimes stops working and I get white noise/beeping :(

Second time I've noticed this coming upstairs with my phone in my pocket, when I got up, I went to turn the phone off, unlocked the screen and "pfftpt"
then I turn it off, and instead of the jingle I get another "pfpft"
Strange, because the exact same thing happened to me yesterday. Could it have been the new firmware update? Anyone else experience something like that? Seems pretty crazy.
So this time, I went to use my phone and when I woke it, the rear speaker started making white noise, much like a stereo when you don't get any signal.
Instead of doing much, I tried messing with the sounds and nothing really happened - attempting to play music just caused it to semi-freeze, but I could still get around it. So I let it sit some more, and then the phone started making really loud funky noises.
So I pulled the battery and restarted it. Now the sound is working fine. I think I'm going to try reinstalling from scratch. Currently everything is stock firmware and the latest update to get multiwindow.

[Q] Phone stuck in screensaver mode

Hi!
I brought my Xperia Play phone USED two years ago and I've never had any problems with it.
However, recently, the phone has started to freeze itself in "screensaver" mode (Where the screen goes black after 15 seconds and locks the phone), but the screen won't light up no matter which button I press. I've had to restart the phone every time this happens.
It's been behaving strange at start up as well, as it sometimes take 20 minutes just for it to turn on, while on other occasions, it won't turn on at all!
Is this problem caused by the battery, or is it the hardware?
Is it with stock firmware?

Yes.
I've never modded it or installed custom firmware/apps.
Have you tried factory resetting it?

Yes, but it didn't fix it. The problem still occurs.
tldr: Black screen, no display, everything works "under" (I can answer the phone etc). Not a flex cable problem because occurs randomly, regardless of the slider being open or closed. The problem also occurs during boot up, so rather not a software problem.
I think I have something similiar. Everything was fine until a few days ago the screen didn't want to unlock..or at least I thought it was that.
Basically the phone sometimes works OK but sometimes if I turn off (lock) the screen, it won't go back. To be precise, the phone works and if someone calls me I can pick it up moving the finger where the slider should be, it's just the display doesn't turn on. Same goes for booting, bootloader logo etc, so IMO it's not a software problem.
Strange thing is that it just randomly pops back, sometimes when I move the gamepad slider, sometimes when I put in a jack cable or if I hard reset the phone (remove battery). I've had problems with the flex cable in the past and this time I know that it's not it (no difference if I open/close the slider).
My guess would be some power supply or LCD driver IC issues, because the screen stops working almost everytime if I put the phone into the dock. Moreover, if the screen doesn't work, the orange charging LED is not working (green and blue are OK). The moment the screen starts working, the orange charging LED starts working too.
it's very strange but I'm used to electronics doing strange stuff. Just wondering if I should give a try disassembling the phone and trying to fix it or just buy a new one or something?
I might add that I have bought a new battery ~3 months ago, but it's been working fine to this point. I have tried if the same problem occurs with the old/original battery and it's the same.
well, any ideas?
edit: This video shows something very similiar (except the backlight): https://www.youtube.com/watch?v=m4p0-kv1cxA
Same problem. And I guess this guy has it too.

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...
