Hi,
My S4 SGH-M919 is having a problem where it appears to turn on, charge, and boot to the OS, but there is no response from the screen. The bottom buttons illuminate but the screen doesn't want to turn on. I've tried removing the battery and holding the power button down for an X-number of seconds, but this doesn't seem to do the trick.
Any ideas?
Thanks.
With the phone powered off, connect the phone to the charger. If you see the charging animation, sounds to me like the screen may be damaged or the LCD/motherboard connector is loose.
Was the phone every dropped or bumped?

Hi everyone,
As the title says, my phone simply will not boot past the samsung logo. I insert the battery, a few seconds later there is a vibration. Then the samsung logo appears, and it shuts down. It does not reboot itself; it just suddenly dies. After it the shutdown, all buttons are unresponsive; holding the power button will do nothing.
I have tried plugging in the charger both with and without the battery inside the phone. When I plug in the charger, the red LED that indicates that it is charging turns on. After a few seconds it vibrates, then almost immediately the red LED light flickers off, and everything is just as unresponsive as before. Leaving the charger inside will yield no results or change.
I have tried to turn my phone on with the battery and charger plug into the phone with a few variations. First, charger first, then battery. The battery is inserted within a second or two of plugging in the charger. The red LED light appears, then the light turns off right before the vibration. The screen shows the battery logo that indicates the phone is charging. This image appears for a few seconds, then it becomes unresponsive as before. Second, battery first, then charger. There are two more variations for this. One is battery, then plugging in the charger right after the battery is put in (before the vibration is felt). After the vibration, the battery logo appears for a few seconds before it shuts down and becomes unresponsive again. The second variation is: battery first, then vibration, then right after the charger. Same result as before.
I have also tried to remove both sim card and sd card. No avail.
I have tried to boot it into recovery mode, as well as download mode. Nevertheless, the phone will shut down before getting into any menus.
I have tried to tap the power button multiple times in case the power button and home button were stuck or jammed. However, I doubt this is the problem.
My computer will not recognize my phone, since I cannot boot it past the samsung logo.
I have tried using different batteries, same issue.
I am aware that a factory reset may be an option that I may have to take, but I have some important data on my phone that is not backed up, and I would very much prefer not to lose it all. I would appreciate any insight on how to fix my problem.
Thanks!
Mine was doing this for a bit until I realized my power button was stuck. The button seemed to press fine and all and looked fine physically, but the contact was somehow stuck. Take apart the phone, direct some compressed air into it using the little 'straw' for the nozzle to focus it... Also try pressing the button a bunch of times hard, etc. And see if that helps.

Fixed it! Opened it up, jiggled around with the power button stuff. I had no idea what I was doing. I blew, with my mouth, really hard on it. Now it works. laaaaaaaaaaaaaaaaaaaaawwwwwwwwwll
You helped! Thankyou
Now would be a good time to backup that important data. A lot of the time, that's is just a temporary fix and it may happen again.

Hi guys, having some trouble with my tablet. Started out of nowhere, but the screen doesn't light up until the device has been fully restarted, in which case once you lock the screen, the problem starts all over again and I have to restart it again. It also lights up when the device is off and the power cord is plugged in, but only briefly. Once it goes away, I can't use the power button or anything else to check the status of charging, only thing that works is unplugging it and plugging back in. It's still sensitive to the touch, there's haptic feedback, capacitive buttons work, it just stays black most of the time. Has anybody else had this issue and knows how to fix it? It came out of nowhere, the device is not rooted, haven't dropped it or anything. Thanks in advance
I hope I'm posting this in the right place but I'm desperate for help.
My phone, HTC 10, froze and then the screen turned off while I was taking a picture.
The charge should have been around 80%.
Symptoms:
The screen is unresponsive.
Couldn't get the home button/finger print sensor to turn the screen on.
Couldn't get the power button to turn the screen on.
A call to my phone could not reach my number as well.
When plugged in to a wall charger or laptop no indicator light turns on.
When connected to a laptop, the laptop makes that connection noise and a long name with QualComm in it shows up.
Tried Power Button + Volume Up for 10 seconds but didn't get any result.
Side note:
The power button was a little faulty before as well.
You have to squeeze it a certain way to make it work.
I need to somehow restart my phone. Any ideas?

Try to clean all buttons really well, if it keeps failing to boot and the phone is still recognized as Qualcomm it's probably bricked.
Simple explanation of the word bricked :
When the phone doesn't boot, when you can't access the bootloader, download mode or recovery it's bricked!

Strange turn of events: I plugged the phone to my laptop because I read somewhere that it drains the battery. Just for the kicks, after a few hours, I unplugged and re-plugged my phone. Suddenly, there was light. The battery light came back. I immediately switched to the wall charger and once I did that the battery icon appeared showing 1%. Now, it's peacefully charging away. Will see if it actually turns on later on once it's charged about half an hour.
I was on a phone call with a friend when I noticed that the screen wouldn't turn on anymore. After the call was done, I popped out the battery to shut it down.
When I take out the battery and plug the phone via usb charger, the screen turns on and is blacked out. When the battery is in, and I 'turn on' the phone, there is a very slight vibration, and after some time the phone blinks that red LED light like when I have a gmail waiting--it is as though the phone really is on and active, but the screen isn't getting signal.
I'm guessing that there's a loose connection somewhere.
Any suggestions?
I disassembled and reassembled. Didn't work initially.
Left my phone alone for 5 minutes after it booted with no screen signal, and then I press the power button, and it turned on.
So weird. Seems like I'd better back up my stuff while I can.
My G4 H811 suddenly not powering on.
It was just working fine. I turn off the screen and then a minute later I try to turn the screen on by pressing the power button and the screen is not turning on. I made a few attempts and tried to power it off and on. That's when I feel the phone vibrates but normally it is just a short vibration before the screen on but the vibration never stops and screen is not on. Pressing the power button does nothing. I have to take out the battery to make it stop (vibrates for about 30s). After that, phone won't even vibrate.
I left the phone charged for 2 hours. The charge indicator never turn on but I feel a little warm just like when phone is charging. Basically, now phone will not turn on. What can I do?
There were a couple of occasions since yesterday that I managed to power on the phone to see the LG logo. But it stays there for about 10s and the screen went blank. Looks like my phone is done for.
