Help my s8+ display is just black - Samsung Galaxy S8+ Questions & Answers

My s8+ suddenly stopped working and kept on getting stuck on the logo. I tried installing the firmware through odin and it said pass.

I cannot go to recovery mode or download mode, I cannot see a charging logo. The phone just shows black screen and is totally unresponsive even if i tried charging through its charger or connected it to the computer

Tab 2 stuck at boot screen - HARD RESET DOESN'T WORK

Hi
I bought a Samsung Galaxy Tab 2 7.0 in Thailand last year. Unfortunately for a while now it's been stuck at the boot screen. I've tried hard resetting (Power on, volume up or down) and nothing appears. The tablet just switches on again. I'm beginning to think I should just give up, as i've tried everything i've heard of. I haven't loaded any new software or anything on it. I can't also try upgrading the software via kies or odin as nothing is detected when I plug the tablet in via USB. It charges normally, the light goes on and the charging animation pops up.
Can somebody PLEASE help?
Also, it doesn't get stuck on a blue Samsung screen. It gets stuck on a green Android screen.

[Completed] [Q] Moto G (U.S Cellular) boot loop. wont charge.

ok so i have a moto g that is fully stock and all my apps were from the playstore and i never noticed any bad lag at all. but one day, out of the blue, i wake up to my phone showing the blue m logo and then a black screen and repeat.
so i tinkered around with it and searched the internet and heres what i found out:
I can get into fastboot mode but cant use any tools except for the barcode tool otherwise the phone just goes back into its boot loop. (yes i selected with the volume up key)
the phone has no power what so ever unless its plugged in. and i dont have to press anything to start the loop, it starts on its own as soon as i plug it in. the led blinks white twice and shows the m logo for about 5 seconds then a black screen and repeats once more then it is black for about 5 minutes then its goes into the loop once more.
i cant flash the stock firmware because when i plug the phone into my computer and put it in fastboot mode, the fastboot menu pops up for a mere seconds then the screen goes black and goes into the loop again.
the phone is not damaged and worked with no problems a few days back. i have been through countless websites!
any ideas?
Hi,
Can you specify if it's a 2013 or 2014 moto X.... And I will have your thread moved to your device Q&A section.
Sounds like a stuck power button to me though.
Thanks!

hi i have a S6 G920f wont charge properly and wont boot into recovery or download.
there was no damage or liquid prior to this,
when i put phone on charge there is no light however screen turns on and show lightning bolt symbol and goes on and off every 10-15 secs.
