Why won't my screen stay off?

Quite frequently when I hit the red button the screen goes off and then instantly comes back on. If I repeatedly hit the red button it just keeps going off and then popping back on. Sometimes it does go off, sometimes it doesn't.
Other times it goes off and then later for no apparent reason it comes back on.
Any ideas?
Turn up your backlight
It's a bug. I know it sounds ridiculous, but this happens when your screen brightness is set to 40% or less. Turn the brightness up, and the problem goes away.
Nice, I turned up my brightness and so far so good...
Thanks.

[Q] Why my NS automaticly lights up the screen after I lock it?

This is really weird, my NS just always lights up the screen after I lock the screen.
I locked screen, the screen went black, then after a few seconds the screen turned on just like I pressed the power button.
Why this kind of thing happens? I have reboot my phone, It still the same.

[Q] Black Screen, but phone appears to work

Hi,
Picked up a HTC one S of off a mate today who dropped it and cracked the screen. Replaced the screen for him but it's still not working. Here's symptoms and what I tried.
-black screen all the time
-phone boots, three buttons at bottom lit up, LED flashes green and if I call him the phone vibrates
-if I hold down the power and volume buttons down, once the home lights have flashed 15 times I see a few lines of flicker for a fraction of a second on the screen and then nothing.
-Touchscreen appears to work as it vibrates when touching it (and I'm inputting text presumably?)
-He hadn't customised/flashed any other ROM on there.
Can someone perhaps shed light on next steps for troubleshooting?
Thanks
Tobias

Iview 795TPC black screen after recovery mode attempt

So I wanted to root my Iview 795TPC tablet by holding Volume up button + power while turning it on.
it just keeps turning on then off until I tried it with 4 or 5 attempts, it wont turn on anymore.
but if I look at it at a bright room or point it with a flash light, I noticed that the screen changes when holding the power button.or connecting the charger
to Dark Green - if the screen is all black, holding the power button at 10 seconds will make the screen go dark green
to Black - if the screen is Dark Green, it will turn black if I connect the charger or if I hold the power button 3 seconds.
im guessing that the device is turned on when the screen is black and off if the screen is dark green

19/6 ParanoidAndroid w/ AK269 - 'SCREEN DOESN'T TURN ON'

Does anyone else get this issue:
Sometimes, when I try to unlock my phone, the screen remains black. Sometimes the capacative buttons light up, but not all the time. Double tapping doesn't turn the screen on, pressing the power button doesn't turn the screen on.
I just press and hold the power button when it happens to make the phone restart, and then it starts optimizing all the apps on start up as well. This has happened 3-4 times in the last day. Very annoying. Any ideas how to fix this would be much appreciated!
