I was at Tafe today and I was just browsing through G+ with the phone flat on the desk and the screen turned off. I pressed the power button expecting it to switch back on but since then it hasn't turned on. It was on 90% but I've tried charging it and it still won't turn on. It turns on and off (i can tell by the notification LED) and when it's on it still rings when someone calls, but the screen just won't turn. There's no backlight either.
I've tried holding the power button for 5 and 10 seconds, and a minute, and still nothing. What else can I try?
Would reflashing be worth a try? Or is that even possible without a screen?
It may be bricked softwared.don't know know.but it looks like your software messed up,and there is easy way to reflash it without touchscreen,just look around in google by typing " LG G2 D8XX kdz flash procedure,download same software and reflash it by puttin phone to download mode(combination of the keys)
are you the original owner of this phone? or have you replaced the lcd assembly before? its possible the ribbon cable is not seated correctly. but if youre the original owner, and you have never opened it, im guessing your LCD just went out.

Noob here, I've searched but no joy on this one...
My Touch HD has just developed a foult where the screen is dead. Nothing happens when I switch it on but the device works...when I connect it to my PC it syncs happily and it rings in.
Which suggests it's hardware...EXECPT
I CAN get the screen to switch on by forcing a power down (hold the power button until the warning appears), if I then cancel this, the screen functions quite happily and will even go in and out of standby until it switches off...
I have tried a Hard Reset (Clear Storage method) but it is still the same.
If I try and flash the ROM, it switches the phone off and the programme fails.
It does occasionally pop up with a Microp error but not every time...
Help, please?
TIA
I developed a similar error today. The phone has worked just fine before.
The screen operates just fine while it's lit up, and when booting it works without a problem. However, if I turn off the screen or if it turns itself off, I can hardly get it on again. The power button itself works just fine since I can use the device blindly while the screen is off (but should be on). So I could launch programs blindly by tapping the screen accordingly. To clarify, the two states are:
1. Screen sleep | Screen is off | Device doesn't respond to touch
Push power button
2. Screen awake | Screen is off(!) | Device responds to touch
What the hell is that all about? In order to get the screen lit up when I wake it up, I need to push the power button perhaps 10 times before the screen actually lits up.
Any ideas?
same problem here
Fixed by Warranty Repair. Replaced one of the boards inside. All OK now
Damnit, my warranty period is out.
Do you know more in detail what they changed?

I have this problem too so ditto the what did they fix question. Was it the mainboard or the volume/power button board?
Thanks!
i had this after 9 months and it needed repaiired under warranty. replaced the motherboard i believe.
I tried to flash the original stock ROM. No help, so off to repair it is.
An update
The repair service needed to change:
Mainboard
Flexible PCB
Display
Now everything is working just fine.
I have obtained a water damaged Lumia 520. I opened it up and dried it while also clearing any oxidation from the various contact points. The phone displayed the bolt+gear icon on screen but the screen kept flashing and fading. I figured the phone needed the firmware to be reflashed so I downloaded the software recovery tool and it detected the phone and flashed the firmware without error. Then the phone actually worked albeit with a black screen, I could hear the little noises and stuff so it was working under the black screen. I figured that maybe the screen could be salvaged by cleaning the contacts and letting it dry up completely, but after I put the phone together it wouldn't work anymore at all, it basically turns on for a few seconds and turns itself off. The software recovery finds it and I can reflash the firmware but it still doesn't work. I tried checking all the internal connectors but now there doesn't seem to be any way to make it work even with the dead screen.
Is there something I need to touch on screen to make it work? I never had a Windows Phone so I don't really know and I can't see the screen. And do you geniuses know what might be wrong with it and how can I tell if it's just the LCD that has been killed by the water or if the motherboad might be FUBAR as well? What could be causing it to turn off after a few seconds? The battery is definitely not dead as I left it to charge for a long time.
Actually I just managed to "fix" it. The screen comes on after I cleaned the contacts and messed with it a bit, it just looks really bad and it's full of line but I can see what's on screen and use the phone. My issue now is that the bolt+gear icon appears at every reboot and doesn't go away. The only way I have to boot the phone normally is to hold camera and volume down after I reboot it. What does this mean? Other than that the phone seems to be working perfectly once it actually boots.
I just managed to bring it back to life completely. Screen contacts were water damaged but I managed to get them working again and now the screen is perfect. It kept getting stuck on the bolt+gear icon after every reboot because the volume+ button was stuck but I managed to unstuck it and now the phone is perfect. So yeah if you have a flashing screen after water damage check the contacts, if your phone doesn't boot and keeps getting stuck on that icon try to unstuck the volume+ button.
A friend has an S4 GT-I9505. It was bought second hand few months ago.
Lately it has been acting up. Shutting down randomly but now it won't turn back on. We sometimes manage to get it back on, but no always.
It isn't the battery since I have inserted my battery into the phone and it still won't turn on. It won't turn on even when connected to the charger.
We figured it might be the power button so we took it to a guy to check it out. The guy took the phone apart looked at the button and said the button is ok.
He put the phone back together and it somehow worked without problems for a few days (up until now).
He said that the phone might be shorted somewhere. The thing that led him to that conclusion is that he noticed that when inserting the battery the phone would try turn on without pressing the power button.
He also said the boot might be dead because the phone won't go into recovery nor into download mode. Even if it manages to boot into them, it will turn off almost immediately sometimes.
The phone is running 5.0.1 GPE custom rom with Googy-Max kernel. No tweaks or mods.
I know this sounds a lot like a hardware problem. The only thing that makes me have doubts is that it works occasionally without any problems.
He looked at the power button. Honestly it's no surprise he didn't find anything wrong with the power button because the problem with the power button is inside the tiny metal casing making up the button, and it's something that can't be seen.
Get a second opinion from someone other than the guy you took this to. However, I believe this to be a power button issue, easily fixed by replacing the button.
As I said, He took the phone appart, took the motherboard-logic board, whatever you want to call it, out and looked at it. He also took that tiny metal casing that forms the power button out, leaving a tiny white "something" exposed. I guess that's what you're talking about
But I really hope you're right and it's the power button.
Edit: We were the whole time there while he took the phone apart and looked at it. So we saw everything he did. And he didn't do anything special except take it apart and put it back together and it somehow worked for a few more days.
I guess it really is the button. I managed to change the rom, kernel, bootloader. The phone booted up. I pressed the button once to lock the screen but nothing happened. 1 second after that the boot menu appeared. The next second the phone shut down and now it won't turn on again. Except for a brief moment to show the S4 screen and then turns off again.
Hello,
I have a Moto X Play which is in great condition, I use a case and a screen protector.
Today I went for a walk and grabbed my phone which I hadn't touched in awhile. Once I got outside I realized it wouldn't turn on no matter what I did. Strange, maybe I left an app on.
I get home, plug it in, and it's at 75%. I play with it a bit and put it back in my pocket.
A few minutes later, I can't get the screen on again. I figure, I'll plug it in, reboot it to clear the glitch, it's all good.
It just won't light up.
I can locate it, it's updating its location, I can call it, it vibrates, it responds to buttons (but not the screen) Nothing seems to be wrong with it other than the screen.
I've tried everything to do a reboot, I've plugged in the short circuit usb dongle thing that usually puts an android device right into debug mode. I think it is rebooting but no screen action.
I have the latest OS for the device (whatever the not-so-new one is) and I am unrooted, locked, whatever I haven't messed with anything like that.
What can or should I do? I am just recently out of the 1 year warrantee.
Thank you,
-Phil
Hold down your power and volume down buttons until it turns back up(night take some time) into the bootloader screen and try to factory reset it.

I've tried this, so far no luck. A bit of an update:
I brought it to a shop, they gave it a light twist and the screen came back fine and was in the setup wizard (as I had remotely reset it). They said the display port may have plugged back in, gave it back free of charge. By the time i got back home it was off again. I brought it back in to have them open it and reattach it for real. This didn't help. They tried attaching a brand new screen, same issue. The screen doesn't light up for reboots, not for factory reset, nothing. I am guessing this is an issue on the motherboard but the fact that a light twist "fixes" the issue suggests to me a light soldering could solve the issue. The repair shop gave it back to me as unfixable but I don't want to give up on it yet. I did have an opportunity to get a Nexus 5 in good shape for 140$ so I did that for now. This gives me time to mess with the Moto X Play. Any ideas?

Ive been having the same issue with my x play, so try this out. turn it on, and have a look at the screen under a bright light, see if you can make out anyting. The backlight might not be coming on, but the screen will still 'turn on' so to speak, you can still make out whats on the display, touch input works etc. I have an issue with the display connector, with a bit of pressure it will work then not work, almost as if the backlight shorts out. it took me awhile to find out that that was the problem. as for a fix, if its the same problem I'm having, then you'd probably need a new mainboard. I've tried everything, new screen, new battery, swapping covers etc.. I have 2 x plays to tinker with and swap out parts.
I've tried using my new phone's flashlight to illuminate the screen with no success (though I will try again tonight, I'm not 100% sure it's on). Looks like mainboard run somewhere around 120$ before the repair cost, seems like it's not worth it. I'll post back after I double-check to see if the screen is there or not.
If it's shorting, I would think it could be fixed with some careful soldering? I do know that when I turn my phone on (remember it's been hard reset and has no SIM card) it vibrates every few minutes, I have no idea why. That's the only odd behavior it's been experiencing aside from the display not showing up.
I tried to look for any sign of the screen showing up by using string light and I didn't see anything that might suggest anything is showing up.
A friend of mine lost his S4 I337m, but found it again after it had been run over by a car. I'm trying to determine if it's worth trying to replace the LCD or if there's other damage.
The LCD is just tiny shards of glass (I'm betting it was face down when run over) but while he didn't find the back cover, the mid frame is in good condition and after removing it, the boards don't have any obvious damage.
If I try to turn it on, it vibrates and the LED pulses blue. Then a bit later it does a longer vibraton and the LED flashes blue. It seems like it's powered up.
If I try to connect to Kies, it just says "connecting" forever and the LED turns red. Maybe it's prompting me to unlock the phone? There's no message from Kies to that effect though.
As I've never used this model of phone before, I have no idea what the normal behavior is. Are there any tools I can use via USB to check the "health" of the phone?
FYI, I'm pretty familiar with flashing Android phones (mainly Nexus devices) and have replaced the screen on a Nexus 5, so I'm not afraid of a challenge. I'm guessing this phone is stock, so probably have a locked bootloader and USB debugging disabled, so I'm not sure if I can expect much. Obviously without a screen I can't do much. Also, he pulled the SIM and SD card, not sure if that matters.
I'm going to try connecting using ODIN next.
I actually was in the same situation as you are about an hour ago. I was able to unlock my phone by using a USB OTG adapter to connect my keyboard to enter in the pin and unlock it. After that I was able to access my files, so i just kept taking screenshots while i navigated my phone using my keyboard - installed SideSync, accepted the permissions, and finally - was able to mirror my phone to my computer.
If your phone vibrates, and the LED works, then try testing the button three buttons when you have the phone on. the red LED light is only on when the phone is either powered off and charging, or the phone is powered on with the screen off and charging, so if tapping the power button changes between seeing the red LED and not (and a small vibration when tapping the back or window button) then that should mean it's just the lcd+digitizer
Anyway, feel free to ask me about any behavior about a working s4 with a broken screen, one more week until my replacement comes in the mail
