LG G4 not powering up - G4 Q&A, Help & Troubleshooting

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.

Phone seems to turn on, but screen completely dark.

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?

Lg G3 Phone not working / not responding

Hi,
Really need some help with my LG G3 phone.
Bit of background
My phone network is O2, my kid was watching a you tube video and all he did was hit skip ad and my phone shut down. My phone at the time of shut had around 95% battery.
The phone does not switch on now, when I insert the charger no lights appear stating it charging nor does the screen come on. The phone has not been rooted or anything like that.
When I remove the battery and put the phone on charge the screen displays an image which states no battery is included but when I insert the battery back in the phone displays just goes dead again and nothing occurs
What I have done
I have bought a new battery and still no joy with that
I have held Volume Button down and Power button and no joy
When no battery is in and the above process is followed the screen flickers after around 13-15 seconds but then still shows that no battery is present
Last night the phone did show a little sign of life. I left it all day by itself and then just switched pressed the power button for 3 seconds or so and the LG boot up screen kicked in but then after 10 seconds it switched off. It has not replicated this again though.
Does anyone have any ideas of what i could try next?

Screen Doesn't Appear to Work

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.

Weird problem with screen/power button

Background -
I bought this OnePlus 5T with a smashed screen to fix.
Paid 70 bucks for it plus the screen is just shy of 150 in total.
I was able to replace the screen and frame which was a little more complicated than I anticipated, but it ended well and the phone seems fine, although the screen quality isn't as good as stock.
***Problem - it seems that for unknown reasons, after turning off the screen pressing using the power button, screen becomes black and won't turn on, not until i hold the power button for ten seconds and restart the phone the hard way. Then the phone turns on and starts working again, but if I turn the phone off with the power button then it won't turn on again. I can tell the phone is working behind the black screen, vibration working, notification light working. But Everytime I turn the phone off with the power button I have to hard reboot the phone to get it back on again. Once this starts happening I have to factory reset to get the power button functioning normally again. It will work normally for a day or two and then out of no where the issue comes back again after pressing the power button - screen won't turn on.
Could it be software? I know it might be natural to suspect the screen is faulty, but the screen works normally until I use the power button to turn it off, and then works normally again for a couple of days after a factory reset ...
Thoughts ?

HTC 10 hard bricks, no warning, won't boot or reset, totally dead

This is a strange one.
HTC 10 2PS6500, Android 8. Has been working fine. Today I took the phone out of the pocket, to find that it's been turned off. Strange, I know the battery was almost full, so it's not a power down due to low battery.
Tried to turn it on with the power button, didn't work.
Held the power and volume up + down at the same time, a few seconds later the phone vibrated and powered up. Battery at 92%. No sign of what might have happened. Phone was working. I wondered what happened but soon forgot about it.
A few hours later, I charged the phone back to 100%. While using it, the screen timed out, when I pressed the power button again, a message popped up saying "HTC recovered from an abnormal reset, send it to HTC" or something like that, and it tells me to tap it twice to send. I tapped it twice, the screen came up. I have the option of Send to HTC or Cancel. I pressed Cancel. The screen froze after that.
Buttons are unresponsive. I pressed the power and volume buttons to reset it, it went black.
Since then I have not been able to get it to respond.
Power button alone - nothing. Tried even holding in excess of 1 minute.
Power + Volume Down - nothing. Held for 10 seconds, 20 seconds, over 1 minute.
Powr + Volume Up + Volume Down - nothing. Held for different durations of time, no difference.
Connected it to a charger, no response, the light up top where it lits when charging does not light up.
It's completely unresponsive. No boot screen, no vibration, nothing at all.
Any idea what else I can try?
well some new development...
I was trying to do the hard reset on the phone periodically. Sometimes with the charger plugged in (but no light on top indicating it's taking any charge). A day later, I was doing another hard reset (not expecting it to respond) but it vibrates and boots up. Since then it has been behaving normally. Strange that battery was at 21%, when it was at 80% when the screen froze. I charged it to 100% then backed up the data while I had it on.
I got about a day of usage out of it, then while I was on a browser scrolling down on a web page, the screen froze again. Battery at 75%. After trying to reset it, the screen went black. Since then, no response on attempts to hard reset.
I have a feeling if I leave it alone for a day and try it it will come back alive.
Doing a search on the net yield nothing except I did see a post someone made saying after the screen froze had to wait till the battery drains 100%, then charge it back up and it will boot again. Is this what is happening? If it's bricked how is it consuming battery?
Anyone has any idea sure would like to hear it.
