[Q] Screen won't turn on, even though phone is powered up - Nexus 5 Q&A, Help & Troubleshooting

Hi guys,
For some reason, all of a sudden, my Nexus 5 is not able to be woken up from the lock screen. This happened randomly. I can still boot into recovery and bootloader by holding down the volume and power, and I can still access my phone, though I have to reboot (by holding down the power button) every time I lock my screen. I'm running OptiPop (F2FS) with Uber Kernel. My warranty is void as I've had the phone for a while, and I would really appreciate if you guys knew a solution to this.
Edit: When I lock my phone, the phone vibrates for a brief second.
Thanks

It could be the "Prevent Accidental Wake-up" feature built into the OptiPop rom. If your phone is in a low light environment, the phone thinks its an accidental wake up and does not turn the display on. I've had this happen to me. Try turning the option off under Settings->Display->Prevent Accidental Wake-up

[Q] How to disable the Volume Rocker!!!

Hey guys, I've had my HTC Desire S for about a month now,
Today I was using it, and the volume kept turning itself up. I turned it back down, and a few seconds later, back up to nothing. Repeated that a few times, and it kept happening.
I played with the volume buttons and they don't feel jammed at all, the vol. up button is clicking fine, doesn't feel stuck or anything. And if that wasn't bad enough, I tried turning my phone off and on, but when turning it on, it still thinks it's held down so it will only boot into recovery mode. so, as a result my phone wont boot up at all....!!!
Is there any solution for this?? can i disable the Volume rocker??? plz help me out guys..........(i have already rooted my phone so warranty is void!!)

not sure about the volume rocker but it is possible to unroot & change to s-on for warranty purposes(not sure about the recovery though)
I put my phone inside a box.
That pretty much disabled the volume rocker.

Nexus 5 problems turning on

i have a 32gb white nexus 5, fully charged. stock OS, rooted with TWRP recovery. using Faux123 kernel.
what's weird is that i am unable to turn on the device:
- if i power off the phone and attempt to power it on
- reboot the phone (it will shut off like it's rebooting, but won't turn back on)
pressing and releasing the power button, holding the power button for X amount of time and releasing, etc will not turn on the phone.
in order to turn it back on i have to use vol down + power...even then i have to hold it, release, hold, release, etc and by random chance the phone will boot into bootloader.
the power button doesn't seem to be the issue because it works fine turning the display on/off while the phone is on.
i have not figured any pattern or why this is happening.
has anyone else experienced similar issues?
Your best bet is to go back to stock. Stay stock for a bit and have a baseline to know how your phone is. Then after you start customizing it with 3rd party kernels, ect, you'll know if it's the phone or mods you did.

[Q] Black Screen with Power on, Can't do Anything.

So my friend's nexus 5 is turning on but the screen is just staying black, like just the backlight is on. The phone seems to fine, he's getting notifications and everything, however the touchscreen doesn't work either.
The phone is pattern locked and ADB wasn't enabled, is there anything I can do?
Has this happened to anyone else?
Could we back it up and flash it although it's pattern locked and USB debugging wasn't enabled before?
The phone is flashed, but I'm not sure if he has root anymore, it might have been broken by an update.
Any help would be greatly appreciated.
long press the power button, about 20-30 seconds. this will power it off/reboot it.

oneplus one won't turn on!!

My opo device is not responding at all. I was using the device normally and suddenly the screen turned black and since than its not responding at all. My device was not rooted and i was using the CM 13.1 stock. The device had around 50% battery when it turned off. I have tried power cycling it and pressing the power and volume down button but still nothing. It won't even turn on and there is no vibration or anything when i am holding the power button. Can anyone please help me!!
Bump. Mine too. Nothing, totally dead. How do I do a factory reset if I can't even turn it on?

[LCD Replacement] Screen doesn't light up after sleep

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.
