LG G3 D851 won't turn on! - G3 Q&A, Help & Troubleshooting

Hey everyone,
I was using facebook while my G3 was charging and it suddenly turned off and since then it's not turning on. I've tried everything I could but unfortunately nothing has helped. There is no display and it seems like my phone is dead. A positive note is, when I put it on charge, display comes for just 2-3 seconds and it shows the phone is charging but then it disappears too and nothing happens. One of the repairman suggests that it's motherboard is not working anymore but to this I disagree cause if that was the case, the phone won't show a display even for a second? Please if anyone could help me. Thanks!

DId you try leaving the phone on a charger for a few hours? Maybe the phone needs a new battery?

Yeah I've tried 3-4 new batteries too, still it doesn't work. But one thing that's happening now is my phone is turning on, but it reboots (or turns off sometimes) when reaches the home screen or just before that. Same is happening when I enter into download mode.

My galaxy will not turn on it just vibrates! Bricked?

Two weeks ago my galaxy just stopped working. it was at a decent battery; just stopped. I tried charging it but the phone would vibrate. phone would come on, then shut off. I tried it multiple times and same result; a few times the phone would make it to the samsung startup animation, sometimes it would just flash the samsung logo, once it compleley got to my screen start before shutting off.
I brought my phone to get fixed. It took a whole week and the guy said my phone was just not fixable. It would work for a few hours then shut off again, according to him. I suspect he didnt work much on it though as hed rather fix phones with easy problems as mine was a tough one.
I've had to replace my phone with an iphone now, but right now, out of curiosity, I completely took my phone apart, and started using tweezers to play the power on button. The camera part just broke off (not the actual camera) but now my phone is actually charging! The red light is on, and click the main button, it shows the battery being charged. This has not happened ever since the phone broke.
Am I bricked? Is there hope for this phone??? Please tell me there is lol.
EDIT: My phone seems to have restarted! Turned it on and it's asking for my simcard what is GOING ON LOL

It just randomly shut off. It was if someone would constantly be turning the phone off as soon as I turned it on. But then I couldn't even charge the phone. No red light, no screen, nothing, just vibration. I would try to turn it on sometimes it would get to the boot up, sometimes not, sometimes nothing, just a vibrate.
I literally took tweezers and lifted the green board out from around the power on button (it's an actual tiny white button on the inside). and then it randomly started working again

Could be a power button failure. Happens somewhat often.
Could be battery related too, a cheap replacement battery could strike that off.

agree with what he said, it could be a problem with the power button or battery is not working
off topic did you really get 176Mb/s download or is it fake
if its real then was it WIFI or DATA , i have never topped 50Mb/s both wifi and data) but DATA seems to be 10x faster than my wifi

LG G3 overheats and won't turn on. Any suggestions?

I've been having this problem for a month.I usually would use my phone for awhile with 70-8-0% brightness and the phone would stop for a couple of seconds and turn off. I've been using CM 12.1 ,Aospal ,and LG stock 4.4. Usually when I turn my phone on, it'll boot up to the LG splash screen and turns back off. I tried to remove battery and turn it on, not responsive. Try to plug in phone without battery, no battery symbol. When I leave the phone to charge with battery, it heats up. The only solution I tried that works is to put in the refigerator ( I feel pretty dumb). I have sent my phone to LG before and never water damaged or dropped my phone.

T-Mobile D851 LG G3 - Turned off on its own, will not turn on or charge

Hello All,
I have a problem that occurred a few days ago with my LG G3 (apx. 6 months old). My phone has been running fine and out of nowhere, my phone turned off and I couldn't turn it back on. Initially, I thought that the battery may have died because I was using a golf app that utilized gps, but my phone was at a 100% 20 min prior to it turning off. When I got to my car, I plugged it into the charger, but I didn't see the charging light and it still wouldn't turn on. When I got home, I plugged it into the OEM charger for about two hours without any success (the phone felt warm similar to when I charge my phone). I've long pressed the power button, tried the power and lower volume button to hard reboot without any success. I bought this through the t-mobile site like my previous phones through their New2U certified refurbished program which comes with a 90 day warranty (expired).
Has anyone experienced a similar issue and if so, what did you do to correct the issue because T-Mobile referred me to LG so that they can direct me to an authorized retailer. Any assistance would be greatly appreciated.
Note: the phone is in great condition.
Thanks
Have you tried removing the battery, holding down the power button until any residual current is discharged, reinserting the battery, then plugging back in the OEM wall charger?

Did you try to go into download mode? Remove battery plug it back in. hold Volume up and plug usb cable. Are you in download mode?
Any word? Does your pc detect it? Kinda in the same limbo... ?

turning off on its own might be due to overheating
Lg G3 d851 turn off
Hi guys i have same problem with my Lg G3 D851. Is turned off after upgrade root but isn't back on. display complete is black, no Recovery mode and no Download Mode. Can you help me?
if you guys are getting nothing when the phone is plugged in either then i suspect either something defective or mobo has lost connection to lcd screen. what roms do you guys use do they make sounds on boot? are you hearing sounds after attempting to turning it on and wait a few minutes?

G4 won't start up

Hi,
I was browsing the web on my G4 earlier today when the screen just turned black, tried turning it back on but nothing happened then my smart watch brief to say it had lost connection to my phone so presumably it had switched off.
Been trying for the last hour or so to stay it up again but nothing works. I've tried holding the power button for 30-60 seconds, pulling the battery, charging it but no joy.
The battery was around 85% charged when this all happened and when I plug the phone into a power source the LED doesn't come on so it doesn't even look like it's drawing power.
Any ideas on what has gone wrong or how to fix?
Thanks
Having the exact same issue (Sprint Variant). Phone was fine, stock/unrooted, sitting on my desk with 80%+ battery. Checked on phone 10 minutes later, never turned back on or responds to charging.
Errr, mine as well.
Change the battery and try a factory reset but nothing change.
My girlfriend's g4 had this three weeks ago, nothing worked to get it to switch back on. She had to send it to LG for repair and it came back today saying they had replaced a faulty main board. Her g4's serial number started with 505.
What do yours start with because I know of at least 3 others that have had the same thing happen over the last month, all after a out nine months of purchasing the phone.
Try the freezer method maybe you can then backup your data at least.
Serial starting with 5xx?

Lg G3 won't power on or charge

I have a LG G3 D851 from T-Mobile. I had it from about two years now. It upgraded to Android M about a year ago and now the phone won't charge or turn on. I tried everything. First I tried to hard reset' but nothing. Next I tried refrigeration. The phone would start up and go to homescreen, but then freeze and shut off. I even bought a new battery, but it would still have the same problem. Sometimes tne phone would start and shiw that screen on but nothing on it, and it would also turn on and turn off then show the led flash red and blue. When I charge it, it would show the battery loading up and shut down, then the phone would keep restarting. Like I said, tried every thing. If anyone could help me that would be great.
Thanks

I would start with replacing the battery. It has been a wbile since i have had a g3 but this was a common issue. The batteries were known to bassicly just keel out
The solution is a simple one.
1 remove battery
2 connect charging cable (I am not kidding)
3 power in the phone
4 the phone will try to boot
5 it will fail to boot or maybe it will boot
6 insert battery while the charging cable is still attached
7 power the phone
8 the phone will boot and show 100% battery
9 reboot phone
The next video shows my phone working without the battery...
