Device turns on, but screen remains black

Hey guys, yesterday my note 3 fell off and the battery flew out of the phone. I connected it, tried to reboot but the screen remains black. The phone turns on, the notification led works, the back and menu button lights are on and every once in a while it vibrates when I receive messages, but the screen still black. I tried to open it and see if something happened to the connections inside but everything looks fine to me. What should I do now? Send it to repair? Do you guys think I'll have to replace the display altogether?

Samsung Galaxy S4 Turns on Automatically...

Hi there I've a Samsung galaxy S4 and I'm facing a problem from last few days.
It works fine but when I shut it down after a few seconds it automatically turns on. it doesn't turning off. When I turn it off it automatically turns back on. Other things work fine.
Any suggestions please.
Your power button is stuck. Gently tapping the edge of the S4 against a table should free it.

Help ! Screen turn yellow flash for short time after I wake it up or turn the device

I have a Galaxy S5 G900F running on official Android Marshmallow 6.0.1, from yesterday, when I hit the power button to turn on the screen , I see a yellow flash ( the screen lights in yellow quickly ) then everything is normal until I turn it off and try to wake it up again ( same problem occurs )
And when I turn it on and off 2 times or 3, the screen turn completely black and I hear sound means the phone is working .
what's going on with my screen ? is it going to get worse by time ? How to fix this please ?
+ the device was on an Orange ( France ) 6.0.1 and I turned it to a UAE 6.0.1 . Can this be the cause ?

Your screen phone is starting to fail. This is a known failure. IT can get as bad as you must need to try to turn the screen on 15 o 20 times. Minimum brightness can also fail

Everything works instead of screen

Hello!
I am new to this forum but I havent found an answer anywhere on the internet. I have a Samsung Galaxy S8 plus with a small crack in the screen in the corner(I dont think its relevant). I have had this phone for almost 2 months.
My problem is: If the phone is locked and I press either the home or lock button, the phone vibrates and it works but the screen will still remain black(lock screen will not be displayed). I know the phone works even when the screen is not working because if I swipe on the black screen, the iris scanner will turn on. I can get it to work but only if I try turning on and off the phone a lot of times until the screen finally turns on. After the screen turns on, I dont have any problems with it(just there are a few lines on the screen from the crack).
Any suggestion might help,
Thanks a lot
well its obviously broken, send it in for repair and pay up bi... man.
