[Solved] Can't turn on screen after kernel flash - Galaxy Note GT-N7000 General

Hi all.
Got a tweaked XXLB1 rom on my Note. Can't remember which kernel that came with it.
Tried out different kernels, but no matter which I try I have gotten this new problem.
Everything boots great. Rom starts. But as soon as I turn of the screen (click the power button) I can't turn it on again. Well, it turns on "underneath" i could take a screenshots with power+menu and heared the "shutter sound".
But the screen stays black, but the backlight increases very rapidly. And many little 'stars' (from the AMOLED screen) appears.
Have to reset the phone by holding POWER.
EDIT: Google found me something: http://forum.xda-developers.com/showpost.php?p=22737711&postcount=882

strange screen behavior (possible help to SOD?)

Hi,
I experienced today a strange behavior:
I used my nook, turn off wifi, let it in my bag for 1 or 2 hours and when i tried to wake it the screen didn't turn on.
At first i though it was SOD but when i looked closer to the screen there was something on it, it was the CM7 boot logo (the tony hawks droid
The logo was not very visible, most like old "ghost image" on CRT screen when he same image is displayed for long periods of time.
I should have taken a photo, i will if it reproduce.
Kinda sounds like it was rebooting without turning on the backlight. Could you see the arrow circling? I've had "n" turn on the backlight with no image, but tapping power turns off the backlight, then tapping it again turns the screen on properly.
Sounds like somebody's state machine has a leak...
i will never know (i pressed power 8s, if it was booting, i just stopped it)

Screen flashing when pressing home button

Hi,
I've been having screen issues with my phone. First green lines started showing on the screen, I turned auto brightness off, and it fixed the issue. But now when I want to wake my phone, it flashes white, but the screen stays off, and it does this for~3 more clicks, the fourth one turns the screen on though.
I'm on stock by the way. Not rooted.
Figured I'd ask before taking it to Samsung.

Black screen after unlocking.

Hi everyone!
I'm having something similar to black screen of death problem. When I turn on my phone, it's working until I lock it.
When I try to unlock it, my screen is black and only the buttons at the bottom and the notification LED is working.
I've tried pulling out the battery and the sd card and holding the power button for 1 minute, and many different variations of this method, but it didn't work.
I'm running on CM 13.0 but it happens on every ROM.
Please help :crying:
This happens on a the latest stock ROM too? If yes, sounds like a hardware problem.

Zenfone max pro m1 Blank Screen

Hello Everyone..
What happened: my phone was suddenly stuck/freezed. I switched it off for a reboot but it never came up again. Now I am stuck with a black screen. The phone was not dropped, not exposed to water.Already triedower button short & power button for 10sec / 20sec ...Volume down & power buttonLeave it for dischargeCharging it over a long time (with original 1+ charger)Connect it to PC (does not recognize the phone)Nothing worked and I cannot access recovery mode.What it still does: it just vibrates occasionally when I press power or volume down & power. However, it stays black, no boot logo/splash screen. Very infrequently (maybe every 10th on/off) there is a short blink of a red warning sign, which i was able to record. It says the "battery is too low, charge for a while before..." even when charged for a long time!
You may have set e light wallpaper backgroud wallpaper that turned the pattern dot into blacks. So basically the dots are there . Draw your pattern by guessing the dots. The device wil be unlocked. Then change the wallpaper.

S5 Screen stays off/black after screen timeout

Galaxy S5 G900F klte with LineageOS/eOS (Android 11) TWRP and Magisk Root.
The Screen works fine after booting the device. But:
- after the Screen Time out starts - the screen stays black (sometimes flickers a bit when pushing power button)
- also if i manual turn off the screen with i.e. pushing the power button - the screen stays black (sometimes flickers a bit when pushing power button)
Rebooting or taking battery out and back in doesn't help most of the time to get the screen back - and after the first screen time out / turning off screen manually it stays black anyway.
So at the moment I can only use the phone at home with my laptop (with scrcpy ).
I don't think it is a Hardware problem because when I boot into TWRP the screen works fine - for testing purposes i stayed for 2 days in TWRP and the screen came always back to life after every screen time out during the whole time.
Also the touch still works even if the display is black - when i see the screen on scrcpy i can see it functions normal when i touch around on the display.
I also noticed that the screen comes often back alive when i first start scrcpy with the --turn-screen-off flag and then push the home button 1 or more times on the phone)
Any suggestions how to fix that?
Is there maybe a graphics driver i could disable/change/switch in the development options?
Screen flickering. Hardware issue with the S5
