Blank screen after boot animation - Samsung Galaxy A51 Questions & Answers

Hey my cell phone suddenly showed me a black screen and he was just lying on the table. It responds to pressing the screen but does not show after booting.
I have already reset the firmware with Odin3, but that did not help either.

Another bricked one, no bootloader menu, backlight loop

I had JB, rooted, unlocked and stock recovery working just fine. I forget the update file in sd card and accidentally go into recovery mode. Screen went black. Backlight of the screen is going on and off every 30 sec.
Forced to reboot, all white boot logo with small "the device is unlocked" print comes up, after a few seconds screen goes blank, and backlight of the screen goes off and on and off again in a continuous loop. No bootloader menu, no adb no fastboot (tried every combination). I can't even turn this thing off.
My only hope is nvFlash i guess, But no good for TF300s for now.

S6 (SM-G920W8) BootLoop

S6 Screen working on recovery mode, but not when phone boots

Hello,
I accidentally dropped my Galaxy s6. When i picked it up, the screen was blank.
Fearing the worst i rebooted the phone. The screen works fine when in recovery/download mode, but when the phone boots normally, it doesn't show anything. The odd thing is that the when it boots normally, the phone appears to be ok... i can press the Vol+ and Vol- and get the usual beep I would expect.
In recovery mode the screen is fine. I can see the bright greeny blue glow with white writing etc...
Please can anyone advise on some tech support for this? I can;t see that the screen is broken becuase it works fine when in downlaod.recoivery.
Help me Obi Wan! You're my only hope!
