S 3 Start-Up Problem

Hello,
I am having an issue with my S 3. It is not booting up as it should. The model is SGH-1747M.
I have tried the following and have had the following results:
1) The phone is non-responsive when attempting to power it on with the power button.
2) If I remove the battery, with the phone not plugged in, and then put the battery back in, the phone begins to power on by itself. It vibrates once and then loads to the Samsung screen and then goes off.
3) If I plug the phone in without the battery, the phone vibrates once and the red charging light comes on but then goes off after a couple seconds.
4) If I plug the phone in without the battery, and then insert the battery as soon as the red light comes on, the charging screen comes on but then the phone goes off after a couple seconds.
5) If I put the battery in with the phone unplugged and hold Volume Down, Power and the Home Button, the phone boots to the screen where you can push up on volume to flash new firmware. If I stay on this screen without pressing anything, the phone turns off after a couple seconds. If I push up on the power button, it goes to the screen with the green android man but then turns off after a couple seconds.
6) If I put the battery in with the phone unplugged and hole Volume Up, Power and Home and then release them on the Samsung screen, blue writing pops up in the top left corner (I couldn’t read quick enough what it says) while still on the Samsung screen and then it loads to a screen saying Samsung Galaxy S III and then the phone turns off.
These problems started when I attempted to connect my phone to my laptop to transfer songs over to it. I connected the phone and the battery was charging, but it wasn’t showing up as connected on my laptop. So, I turned the phone off to restart it but when I went to turn it back on, these issues started.
The phone was rooted and has been for the last 7 months without any changes to the firmware or updates to the firmware in that time period and has not encountered any problems prior. I’m not sure what firmware the phone was on prior to this.
If anyone could offer any assistance with this it would be greatly appreciated.
Thank you in advance.
Hi,
I'm no expert, but it looks like a faulty/stuck power button. It's normal for the phone not to completely boot up when it is powered off and then plugged in to USB. But it is not normal for the phone to reboot itself when in recovery or in Android. That's why I think the power switch might be the cause.

GNexus wont turn on & I cant reboot :(

3 days ago on my b-day I charge my phone only to power it on and have it immediately shut off on me. I plug it into charger and it was still fully charged so i turn on agian and it does the same thing it will just immediately turn off on me. Now its gotten to the point where when i try to power it on the word google pops up and it brightens after abotu 3 seconds then phone turns off and continue to charge. The phone battery indicates it is fully charged however it wont turn on. May i remind you my volume down button does not work so i can not Volume keys and Power button reboot. Plz help
I wonder if the hardware has broken somehow? If just the power button broke, this post says to remove the battery, plug phone into computer, then insert battery: http://forum.xda-developers.com/gal...rnative-to-t1731128/post65166854#post65166854
If only the software has broken somehow, maybe you can flash a new ROM from the beginning using one of the nexus toolkit apps which automate everything for you.

One Plus-3 Black Screen. No LED No Vibration. Hardbricked?

So I had kept my oneplus3 on charge at around 10:00 Pm yesterday and fell asleep. Woke up around 12:00pm to see it was fully charged so I unplugged the charger kept the phone beside me and went to sleep. Today when I woke up I saw that the phone has a black screen and is completely dead. The LED light is not on. Plugged into the charger no response. Tried holding power button ..nothing. No vibrations or home button lights
Currently, there is nothing going on with the phone. No flashes on screen no LED. Absolutely nothing. Tried connecting to laptop (windows 10) dont see anything. It was working perfectly fine last night and i had used it for nothing but music then.
Question is.. is the phone hard bricked or completley bricked? what might be the reason? I searched youtube only to find 1 person with similar problem who had said that he kept the phone for 48 hours and when it was completely discharged he pluged in charger again and it started working.
I am confused. Have a lot of work documents inside and what if it stays the same after 48 hours?
Appreciate any help on the matter
update: Tried plugging in the charger a few min ago. The led turns red and Vibrates. Nothing else
Update 2: so after 24 hours of setting the phone aside. i plugged the charger and it went into charging. But now am facing a new problem. My bootloader is unlocked and the power button is busted hence whenever I press volume down and plug-in the charger it takes me to bootloader warning screen from where either it goes into charge or i press volume key and it goes into option which I again cant select cause power button is busted. Tried holding down the power button and connect to laptop(windows 10) no device detected and it works like normal charging. Tried to charge for a few minutes unpluged charger and start again .. it was stuck on oneplus screen. Any ideas??

Help! My xperia xz2 compact won't power on, no response to charging

HI everyone,
This morning I woke up to my phone not responding to power button. Screen stayed blank. The LED was blinking white, very fast. I tried a combination of hold power button, then power button + volume up, but nothing. At some point of trying these buttons the LED went off.
Now the phone is not responding to charging cable on power, charging cable in PC USB, and power button/volume up combination. I even took the SD card slot out to try. Been on the charger for at least 30 mins now.
The last time I did was playing a mobile game on auto-mode (which I often do and leave it to run until it runs out of stamina), but it shouldn't have drained the battery befote it finished. I go to sleep when it's doing that so no idea what happened on screen before it went dead.
Um, before I start to panic, can anyone tell me what's happened?? Help please?

Razer phone blank screen (no boot logo) and only vibrates once when boot up then turn off - help!

So this morning my Razer Phone was all fine until it suddenly vibrates twice then the screen goes blank while in my pocket. I once thought it was just ran out of battery so i left it charging for a moment. When i tried to turn it back on, the phone only vibrates once and the screen turns on but appears blank. Even the razer boot logo doesn't shows up. After few seconds the phone comes back turned off.
The charging port is fine so are the charging cable and the adapter. Power button, fingerprint, volume button are all working normally. I also can feel a little heat on the phone while charging just like usual. I think the hardware seems to be just fine. I've tried to get into the recovery mode by holding down power and volume up button for 7-15 seconds but didn't work. It only brings it into the 'blank screen' again like when i'm trying to boot it up before.
I don't know how could this happened all of sudden, i never did anything fancy to it apart from playing games, using apps and such.
Any help would be appreciated.
There maybe two reasons there is a bug with you droid or apps & services running tho or an app or a mod you installed corrupted your systen
did it reboot in recovery or fastboot
u can try to boot to bootloader on PC , turn off your phone then plug in PC by cable, hold volume down + power button to boot to bootloader .
