White Screen PLEASE HELP!!

So after installing the WM6 ROM Core 2.0 and using it for a while i started to get this white screen, after using it for about a month, that would keep on appearing if unless i had the keyboard slightly slid out. So i decided to switch to Faria's Pro ROM Kitchen hoping it would fix it, but it didn't. This white screen that keeps popping up covers the entire screen and nothing i do seems to make it stop. This screen is really annoying especially when trying to watch movies and when coming out of wakeup and receiving phone calls, as it covers the whole screen not allowing me to see. Is there a way to fix this so this white screen does not keep coming up. I would really appreciate the Help.
What do you mean exactly by "white screen coming up" ???
Does your screen turn blanc or is there a window popping up?
If you can do the following without having too much trouble with backing up and stuff like that: install you shipped ROM for a while and see if it still appears!
Other than that I guess there is a hardware problem!
Well its a blank screen that covers up the whole screen its not like a window the whole screen just turns white. I did install the T-Mobile 2.26 ROM when i switched to Faria's WM6 ROM, but it still was there for the short time i had it.
Do you have your phone passworded? That causes a white screen to come up just after you wake your phone if you don't have it set to ask for the password upon wakeup. It usually goes away after about half a second but maybe yours is sticking there for some reason. Try turning off your password and see if that fixes it. You may not want to keep your phone without password protection but at least you'll know whats causing the white screen. You might also try changing the "prompt if device unused for" to a longer duration and see if that maybe helps.
well i dont have a password set, so i dont think it is the password, the thing is that it doesnt only come up after wakeup, if the device does not have the keyboard slid out slightly it will come up just after about 40 secs. Sometimes it comes up right in the middle of me doing something like changing some options. If i have the keyboard slid out all the way it will do the same thing. It only does not come up if the first rows of keys at the bottom of the keyboard are visible. Has this happened to anyone else? is there a way to fix this?
Someone help PLEASE.
Sounds like your phone is undecided whether it wants to go into portrait or landscape mode..
What do you mean? if my phone has the keyboard closed then after about 20-40 secs the entire screen will turn white, then when i slide the keyboard out just slightly the screen goes away, and as long as i have the keyboard slightly slid out the screen wont turn white. I am thinking of sending my MDA in to get a Wing, does anyone know if i am allowed to do this since my MDA is acting werid?

Replacing an lcd/digitizer/screen

Can you help me I have an Orange spv m3100 that has no display on the screen the screen switches on well a light comes on, yet there is no display start buttons etc displayed. When I use the buttons on the side etc they make clicking noises and everso everso faintly I think I see things moving ie when I click the windows button on the screen I think I see the start menu drop down (but to indistinguishable to do anything with.)
Can you tell me what parts you think I need to replace lcd/digitizer/lcd and where I can buy them from.
I have not backed up any of my contacts and all I really want to do is retrieve them then I dont care what happens to the phone. So any suggestions how I can do this would be greatly appreciated.
an active sync connection should put all your contacts onto your computer,
conversely get a software like true connect and then you can control your PDA from your computer screen. - this software puts a small window with what is on or what should be on the pda screen.
hope this helps.
If you want to replace your screen, send it to apex laptops in england somewhere!
PS is your screen just blank and white? - Cuz mine is doing that at the moment, whatever you do - do not hard reset your device.
I think its a connection problem with the pins in the cable.

My phone display is not waking up by double tap or by power button and hence i'm not able to use the phone. Rest of the phone is working fine.
I'll be grateful if somebody could help me out on this issue.Thanks in advance.
Same is the case with me. I was asked to try resetting any changes made in the Performance menu. Try it, this may help.

Please explain more clearly-
If your phone is not waking up by double tap or by power button, does it wake up on an incoming call ?
How can you say that rest of the phone is working fine ?
YUREKA YU screen blacked out after reducing brightness
My phone display is blacked out after i reduced the brightness bar... can anyone help how to enable the screen
Flash a torch at tip of the phone near the sensor....then you have to be quick to increase the brightness
As someone reported, if you enable automatic brightness and color correction and reduce the brightness to the lowest, the screen would switch off forever. The only way back is a factory reset or restoring an backup.
just managed to fix this
I was in a real hurry yesterday and must have accidentally set brightness to all 0. And then bam..black screen
here's how i fixed it.
Downloaded this: http://droid-at-screen.ribomation.com/installation/
This mirrors the phone screen on pc using the jar file. Needs adb debugging to be enabled and accessible from pc.
Doesnt allow you do send touch inputs though.
Probably other solutions exist, like miracast etc. But the above app was my first try and it worked.
I kept my super awesome OPO next to the yureka, as a reference for screen position.
looking at the yu screen on pc, i activated, logged in to the phone, and then pushed my brightness up. All on a blank display. Also doing the same in parallel on the OPO, for reference point.
And, the yu screen lit up.
(if not this, may have to edit some system files, but didnt work in my trials..or backup device and then factory resent and then restore back)
How to fix screen goes dark after manually setting brightness zero
Almost all users are facing this issue. If you manually move the brightness slider to low (extreme left) the screen goes completely dark. You will not be able to see the screen. I tried it but kept the finger on the slider at all time so that I could move the slider and get the right screen brightness.
If you had manually changed the brightness to low and removed your finger from the slider. You sure are looking at a blank screen though the phone is still active. To fix it you will need to blindly follow these instructions. Your phone screen is dark, you will not see anything, unlock the phone (hope you are using swipe to unblock). Once done use two fingers to swipe from top screen to bottom. Note you will still see a blank screen, now tap and hold the finger in the center screen a slightly above the volume down button line – that is where the brightness slider is. If you don’t see the screen lighting up, tap again around the same area, you will get.
ok

This was the exact problem I faced rather than as mentioned every where fix for
Proximity sensor .Tourch solution is the quickest one to resolve it.
In my case I used another smart phone to put light on yureka just there where microphone or message notification led is there.Miraculously it works yureka reflect back then
You bring back normal brightness.Explaining this as original and was too short to
Comprehend easily.

Though this issue may have been solved , the problem mostly is the proximity sensor setting. In dialer, dial *#*#7769#*#*.
This is the setting/calibration window. Press start and keep your ear to the sensor. Remember the value and press exit. Mine was 49.

[Q] Screen from another Note 3? Please help

Background:
So my wifes screen on her Samsung Note 3 is completely smashed, and I believe the digitizer is too as the screen does not respond either. the phone turns on as the buttons has lights and I also get a heptic feedback when I hold down the power button on the phone to turn it on.
I need the the photos, photos were not backed up, not on the SD, and USB Debuggin I believe was off. I tried to connect the phone to 3 different PCs and with different cables, but the pcs do not allow me to see the phones camera folder.
replacing the screen would cost more than the phone cost, and the phone is anyway only being used as a second phone so don't want to shed out that much money.
QUESTION:
I have another Samsung Note 3, so my question was, can I take the screen and digitizer from that one and put it on the broken one and then get the photos and then swap the screen and digitizer back?
Also at work we have a Cellebrite device, but when I tried to extract all the data out of the phone with that, the device asked me to press on "allow this computer" on the phone, but as the screen is broken I can't do this :/
I would really appreciate if anyone can shed some light! thanks guys

Yes I believe it is possible to do such a thing as long as you are prepared to spend enough time on this. Look on YouTube and ifixit and the internet for screen replacement videos and guides and instead of replacing with new screen use the guide to put that other good note 3 screen on your broken one, then use the same guide again to disassemble it and then do as you please by either leaving the broken screen phone or putting the broken screen back into the phone. So yes it is possible but be careful and look at guides carefully.

Touchscreen does not work, any way to recover data?

Hello!
The phone was dropped and the touchscreen is dead, the display is OK.
You can turn the phone on or off using the physical buttons.
When you turn it on it asks for the pin code but it is impossible to input.
Is it any way of recovering the data, pictures, etc?

Hello. I think you have exactly my issue and your back light of screen stay off. You can see what is in your screen if you expose it to sun light or a powerful source light like the flash light from other phone. You can try access your phone in this way and move your level brightness to a lower percent. On my phone is working under 40% and back light display turns ON and stay ON . Don't forget to uncheck automatically brightness option.
If there somebody which can help us to solve this issue ??.
My suspicion is about proximity sensor . I ordered one and tomorrow i will replacing it with a new one. I'm very curios if this will be a good try.

If you have an USB adapter you can connect a mouse through OTG.
