[Q] S2 screen won't wake it just flickers and goes black

My S2 boots up fine (screen very bright and animation color not natural) after finishing boot the soft keys lights up but the screen goes black. When i press the home button the screen just flickers, shows the screen for a split second then goes black.Sometimes after many attempts pressing the power button it wakes but screen at full brightness and color is not natural. When i try to press the screen brightness to adjust it goes black immediately.
What i have tried so far, bought a new LCD screen and replace but problem persists. So its not a LCD problem. It was running stock ICS so i flash stock JB after wiping, no help. Root with Philz kernel but when i go to recovery screen goes black so i try Speedmod kernel with CWM recovery and the screen shows the Recovery menu I try to flash a custom rom (can't remember which one) but it won't boot up stuck at splash screen.I even flash GB and ICS stock still no luck.
The phone works fine calls can still get through, download mode screen and recovery screen ok. I actually have not use this phone for a year but the last time i use use it was working fine.
Google all the different Samsung device if anyone has this problem but no one seem to have the problem that i have so maybe if anyone knows or suggest anything else which i haven't tried.
Thanks for viewing
I have found the root of my problem, the damn brightness control in settings is not working. Brightness is at full, unable to set to auto or manually dim the screen.
Screen will only wake with black background. Have to tear apart the phone and figure whats wrong

Galaxy S7 screen flickering bars / green gradient (Green screen of death?)

Hi,
My Galaxy S7 froze up this morning, and when I hard rebooted it the screen will either flicker green lines, or slowly fades into green bars. This happens whether it's in the OS, recovery mode, download mode, or anywhere in between.
The fingerprint reader and touchscreen still works, since I can hear the unlock sound from fingerprint or pattern.
A few hours ago the screen started working again for a few minutes, and stayed fine through a reboot from recovery mode into normal OS, but then went back to how it was.
The phone is rooted, and I had been running the phone in greyscale mode for the last week using CF Lumen.
Do I need to fully replace the front display and digitiser to repair this?

Black screen

I just got this s9 plus yesterday, I do the necessary settings and updated it but whenever I want to login my mail, it won't let me but turn to black screen without seeing anything on screen again except black screen ,screen will come to normal after I locked and unlocked the phone.. please what can cause this and solution to it

replacement screen doesnt unlock after screenlock

Hey guys.
I replaced my camera module and since in this process i broke the screen, i also replaced the display.
now the display works, but is ghosting, and even worse, when the display is turned of for a running phone, the screen will remain black.
When i restart, the screen works, the blackscreen comes only when i turn the screen off or screenlock kicks in
any ideas would be appreciated!
