Hey guys I notice sometimes one every month or so when I turn off my phone (standby mode, not hard or soft reset) the phone is still on however its a black background (backlight)
What causes this error to happen? the only way for me to get rid of the backlight issue is by pulling out the battery and turning it back on.
i am having the same issue and it is draining the battery! i hope someone figured this one out

did you solve your problem? i have the same issue too.
[Solved the problem by using mymobiler to adjust the screen brightness]
I installed CM 10.1 successfully. However whenever I press the power button the display does not wake up. However the screen does not turn on. I have to restart the phone for the screen to turn on. The buttons however do glow.
Anyone else have this problem and were able to fix it?
Thank You,

Hello everyone,
I bought a LCD replacement for my OPO, and asked a friend to replace the screen (he had his own OPO, and changed the screen on it a couple times, so I trusted him).
The frame was not included, so the phone is without it unfortunately.
But I have this problem with the screen itself...
I boot the phone, everything goes well, it boots, everything ok, I can do everything...
Then the phone goes to sleep after the 30s, and sometimes when I press the button to turn it on, the lights in the bottom light up, I can hear sounds, I can swipe to answer calls for example, but the screen stays all black.
If I press the power button to turn it to sleep mode and then click again to wake it within 1 or 2 seconds, it works everythime.
Its just when it goes to sleep... And then I have to press the power button to reset the phone, and it boots again.
I'm using the LineageOS Rom, and I never had problems like this before replacing the LCD.
What caused this? Could the screen be "broken" when I bought it?
Thank you for reading this and for the help!

Well,clearly the issue is lcd itself.Happened with me on my last screen replacement,it was defective.Though in my case,I had to power on/off the device to get the display back.Get a refund or replacement,there's no other alternative.
Hello!
I woke up this morning with the alarm of my recharging Oneplus 7 only to find out that the screen wouldn't turn on, so I couldn't shut the alarm off. I unplugged it, still nothing, re-plugged it, still nothing.
I then proceeded to force it off by pressing volume up + power for a few seconds and it made a long vibration, showing I think that it rebooted.
But the problem is still here!! The alarm still repeats every 5min and the screen won't turn on!
I tried all this multiple times and it's not working...
Any idea that might help me please?
Thank you!
If your phones screen doesn't show anything even when in bootloader i think your screen is dead
