When my phone boots up it shows the logo then it shows at the top where its checking internal card whatever then the screen goes blank, it only comes up to view when i touch the top button, i think its booting to the standby mode it did it before gingerbread update and after ,i dont really mind cause all i need to do is press the top on button once to get my display up just it seems a bit strange to do this though evry time.

Yes, it aint there. Been looking for it also. I'll try to if someone has successfully changed it. Probably a setting in the build.prop.
If you read the post carefully you might figure it out by yourself!
Its a simple settings option that tells the screen to go blank its in settings/display/screen timeout on all stock roms.

Hi all !!! Sorry for my English but I need your help
I commented what is happening with my phone N5 (which for good and evil is always stock without root or anything, with corresponding OTA updates.)
1- Yesterday afternoon at lunchtime while reading a book in playbooks, I notice that suddenly disappears one line and then appeared intermittently. I close the app and noticed the same thing happening on the screen menu. I shut down the cell and turn on again and I thought it must be an application be kidding. But still does.
2 Also yesterday I happened to change the security on the phone screen. After a while of normal operation, try to turn it on the screen with the button, nothing, the screen goes "black", with light and retrolight turned on but no picture no nothing .
Called the cell to see if it works or is turned off and the phone rings but the screen nothing. Try turning it off and on again by holding the on / off / lock button and the phone restarts, but the screen nothing. In one such attempt to do the above it is seen that managed to turn it off. And I get it on and do a normal boot, except that the picture of my screen is changed to the original. Change the lock screen which was previously using (slip). And it seemed that out or some conflict with the lock. In one of those again pressed the ON / OFF / lock as would normally and it starts all over again.
After I magically back to life, I want to make a full wipe as I think it should be an app that is doing some conflict or something. BUT ....
3I turn off the phone and then press the keys VOLUME UP / DOWN and ON / OFF is normally off, squeezed the first screen with the options but options RECOVERY / BOOTLOADER appears in red I choose RECOVERY give the ok with the key and .... andriod robot appears with the legend below that says something (I do not remember well) without or without controls options appears. So its seems thatI dont have recovery.
After that keep pressing the key ON / OFF and the phone turns off and / or reboot normally. All this I did it again to see if the error reappears and looks that I do not have recovery.
The failure of the screen is increasing. I dont know if they are separate problems or is it all the same problem.
Sorry if I was too long but I need the help of you.
UPDATE Now it seems that the screen died, since I do not achieve to turn it on as before, the light and the retrolight its ok. The phone receives calls and notifications but the screen stills black.
Thanks all.

sometimes things just "derp". itll happen more often if you dont reboot your phone often. also, your phone will be a little bit more responsive if it gets reboot once a day or two.
RMA or fastboot it back to stock, if the screen doesnt turn on afterwards then it looks like a hardware issue, open device and reconnect the display.

just reflash your phone with a tft file. download flashtool and grab your self an tft file from here http://forum.xda-developers.com/xperia-m2/general/ftf-d2303-18-3-1-c-1-15-t3101082 or google.

Phone locks? Strange. I don't meant the OFF button thats next to volume buttons mate. I mean OFF button next to SD CARD. On the back of the phone where you have to open a little plastic stripe cover on SIM and SD card. There is a little, tiny OFF button thats so small that you have to push it by a pin or something as small as it.
Otherwise you will have to flash tft but I think you can manage without it unless you do what I wrote. Or get into recovery and do factory setting. No aplication will beat it.

Try holding vol up and the power button till it vibrates it's the same as taking the battery out.
D2303,18.3.1.C.1.15 kk, deodexed, debloated, rooted, philz touch recovery, bravia engine 2+x-reality+z3 super vivid, viper audio, xposed mods.
I have a Moto G 4G (with Lollipop) with the following problem. As soon as the boot sequence completes the screen turns black. It is not broken because the boot animation is shown, and I can take screenshots by pressing the power button and VOL DOWN. I can also see the screenshot animation (a white square that shrinks on the screen) and hear the shutter sound. By holding the power button the "Shut down" dialog appears and it can be touched, resulting in the phone shutting down.
The problem is similar to that described in
http://forum.xda-developers.com/moto-g/help/moto-g-bootup-problem-recovery-mode-t3122492
I have tried running the phone in Safe Mode. Nothing changes (except from the Safe mode text in the lower left corner). I have also tried wiping the cache from the recovery twice to no avail.
Can you help me diagnose the problem? Or at least, is there a way to backup the data from the phone before attempting an hard reset? Please notice that the phone is locked, unrooted and the usb debug is not active, so I can't use ADB. No SD card was used with the phone. My primary need is to recover photos and Whatsapp data.
Thank you for your help in advance!
I thought you put Adaptive Brightness is on and Brightness lever is minimum. Go to dark( very dark to see the screen) place and go to setting,turn it off. Hope to work.

I'm not sure about this, because I can see the screenshot animation, the shutdown menu and the "Safe mode" text (when in safe mode) clearly. The behavior of the phone is very similar to that shown in the thread I linked in the OP (there is a video there). However I will make sure when I'll have the phone at hand.
That linked u show i dont think same your phone. Yours still working, d other cant boot up, yours can screen shot, got into Safe mode mean its working.

It boots but the screen stays blank in the linked thread. Anyway, it's not a brightness problem in my case as I can see things on the display at daylight.
Hi,
I have a very strange behaviour happened to my nexus 5 after upgrade to android 6.
When my phone is unlocked and screen on, every around 30 sec my phone will show an empty message box like the image 1 below
hxxp://postimg.org/image/c2c3idkeh/
hxxp://s28.postimg.org/c2c3idkeh/Screenshot_20151203_002123.jpg
it will cause the screen which already at dim stage (normal dim screen before screen turn off) to turn back on again (like the screen has received touch input) thus the screen will not turn off if i don't intentionally press power button to turn off screen.
I find that the message box is similar like in the image 2 below
hxxp://postimg.org/image/5hbl93gh7/
hxxp://s17.postimg.org/5hbl93gh7/Screenshot_20151203_002206.jpg
It's very annoying because the empty message box keep showing whenever i use my phone. And if i forget to press power button to turn off the screen, the screen will stays on cause battery drained very fast. I still can use my phone normally tough
it happen both on stock ROM and cyanogenmod ROM (I'm using "12.0-20150202-NIGHTLY-hammerhead") but it doesn't happen when the phone on recovery mode.
My current phone setup :
Nexus 5
ROM : Cyanogenmode 12.0-20150202-NIGHTLY-hammerhead
Recovery : twrp-2.8.7.1
Anybody know what cause the behaviour and how to fix it?
appreciate all the help
I can't post link yet so I have to change the link for http to hxxp
It is the second time this happened. Last time it fixed itself after half an hour.
The screen is always pitch black and the device stays warm.
Most of the time it is boot looping with a black screen, the 5G led on the back keeps blinking in different colours. When connected to a PC, in Device Manager I can see two "LG-V500N", then it disappears after a minute, and comes back, repeat.
Sometimes the device boots and stay booted with a black screen, I can tell the device is on because it is listed in "adb devices". Unfortunately I don't have any authorized device to connect to it via adb.
I am not sure what I can try, I have pressed and hold power + vol down many times but the screen remains black.
I also have trouble switching off the device, it seems to either stay on or boot loop.
After letting it rest for a few hours, switching it on shows this screen, with a white/gray line at the top of the screen, and after 5 seconds it switches itself off again.

Get into download mode by powering off the phone and pressing volume up while having it plugged into a PC. Then find a guide to flash a kdz lgup. You will probably lose data or have already lost it

It seems the phone will not stay in download mode for more than 5 seconds, it powers off after showing the big download mode screen for 5 seconds.
I will try to leave my phone on the charger for some time and then try again.

I managed to get the device to enter and stay in download mode, however the screen stays pitch black and I am not sure if I should continue flashing.
Would you go ahead and flash it if you were me?
The device is currently on Pie, I will probably try flashing a Pie KDZ first, before an Android 10 KDZ.
Sometimes there is a brief moment where the screen comes on, that's when the LG V50 logo shows before entering download mode.
Did an UPGRADE with V500N11r_00_KT_KR_OP_1017.kdz, which should be the same firmware that the device is already on, it flashed successfully, didn't seem to help, screen remains pitch black.
Did a REFURBISH with the same kdz, didn't seem to help either.
The phone seems to continue to boot loop after the REFURBISH flash. When connected to PC, LG-V500N shows up and then disappears repeatedly. Sometimes I can hear a sound effect being played from the phone, sounds like it has booted and the sound probably came from the initial setup screen.
Seems the phone has stopped boot looping, it is on the initial setup screen. The screen remains pitch black but it responds to touch.
Not sure where I can go from here.
Edited:
The screen has come on briefly once for a few seconds, it is on the initial setup screen. I only had time to switch the language to English, then the screen went black and the device seem to have crashed (no longer makes sound or vibrate as I randomly tap on the screen)

I think it's some faulty hardware at this point. You've tried everything possible as of now.

Hi! I bought an LG V50 and exactly the same things you described happens to me, the screen starts, it shows the logo, but then it goes completely black, but phone starts, sounds are heard and the touch screen work. But not image, screen is black. Could you find out what hardware defect it is? It's the display module, or will it be the motherboard? Thanks
Nope, I have sold the phone as parts.
