To keep it short: I have a VZW HTC One unlocked and rooted running a 4.4.2 Nexus 5 port. Everything is fine and dandy until today when the screen shuts off. Phone is still completely responsive in that I can adjust volume, unlock, computer recognizes it, etc. I have found a lot of threads about HTC One black screen and noticed that there were a wide variety of causes and such so I am trying to consolidate information about this particular problem here.
Prior to this issue I had not flashed anything since January, sideloaded any APK's in as long. No problems with the rom, no abnormalities, etc. Was sitting and playing Jetpack Joyride when the screen shut off. The hardware buttons were still on. Rebooting the phone multiple times made no difference. Audio still works (can hear notifications).
What I have tried:
Rebooting the phone while aiming a bright light at the ambient light sensor (assuming the sensor is on the top bezel, I could not find any concrete evidence of the location).
Forcing a reboot through Fastboot.
Reinstalling HTC One drivers and doing it again.
For whatever reason it seems that fastboot can recognize the device but not ADB...
Now if no other solution presents itself, do I need to backup, reroot, relock, and send back to HTC for a replacement?

I have recently purchased this phone via swappa and haven't had any issues prior to this and that has been three weeks (other than a light leak).
The issue that is happening is the LCD will not turn on. When the phone is unlocked via knock on or power button you can move your finger over where the lock circle would be and feel the vibrations showing that it does register the touch. Then usually I would just hold the power button till it rebooted and this would sometimes fix the problem, on a side note the boot LG logo and boot animation do not show up during this time simply the lock screen would randomly appear.
That is problem, now on to what I tried to fix it. I have put on an entirely different rom and the problem persists, I have also flashed a different kernel on the stock rom with no avail. I at first thought it could be due to a faulty proximity sensor, but the last time the screen was on I checked it with sensor box. One way I have been able to reproduce the problem is after locking it putting it in my pocket and waiting around five minutes, this then will make it so the LCD does not turn on ( Which makes it seem like it has something to do with deep sleep). Also something I just found since I was actually able to find the power off button, the screen also won't turn on when the phone is off and plugged into the charger (this makes it seem like hardware issue). It seems like as long as I keep the phone from going to deep sleep the LCD will turn back on.
Some of this makes it seem like a software issue other things make it seem like a hardware issue. I just was wondering if anyone had any ideas or if I need to buy a new screen, if the mobo is bad, or if I could fix this with software. Any and all ideas are welcome.
Thank you all in advance.
Hi,
Have not posted in here in a while but i'm having a huge problem with my HTC one M7.
Had the phone for a year now and suffered a problem with it once before. The problem before was something to do with the phone locking itself and required me sending it off to HTC to repair. It kept bootlooping and wouldn't allow me to do anything at all.
This problem hasn't occurred since repair however last week the phone was working fine until the next morning when i woke up. My girlfriend used my phone to send herself some photo's and then put the phone on charge as the battery was running low. When i woke up the screen stays black and wont allow me to do anything. If i hold the power button the bottom two lights flash and i can hear the phone booting itself back up. I have a feeling the phone works since everyday at 6:15pm my alarm goes off and i am able to deactivate the alarm by swiping up (i remember the location of the dismiss function) it would appear i'm also able to receive calls and texts since i can hear my message and ring tone going off however cannot see the screen.
I have tried a few things such as holding buttons to reboot, shining a light onto the sensor during a reboot and fully charging etc however nothing.
I should also add i have a slight hairline crack in the screen which occurred about 9 months ago but didn't appear to affect the LCD at all or the digitiser either. Any help would be highly appreciated or any tips on stuff to try.
more information available if needed.
Many Thanks
Kris

It looks like you tried all of the usual methods, sorry but it might just be the screen is shorted.

I thought as much, i have ordered a new screen and once its delivered i am gonna attempt to fit it and see what happens, thanks for the reply.
I have a strange problem, well a few. If I lock my phone (C6903) using the physical button I can't unlock it again. I try for about 5-10 minutes sometimes and it just wont work. If I hold it down I can feel it vibrate as if it's bringing up the power menu but the screen just stays black. Eventually it will randomly wake up then I can play around as normal. If I leave it to lock itself I can unlock every time, fist time no worries. This is what pointed me to it being a SW problem rather than a hardware problem.
I also noticed that when I do have the screen turning off in the dark, I can see that the screen is still lit up! Just it is black, not completely asleep. It's really quite bright when I have it next to the bed. Also when I am outside I can't see the screen at all really, even with the brightness turned right up.
It's really strange all these happened about the same time. I figured maybe it was a ROM problem and a fresh install of stock ROM would help. Tried it and at first most of these problems went, just the fact I still couldn't really see the screen in the sun. I tried another ROM and at first was just the same but then these problems started again.
Has anyone had any or all of these problems or got any ideas what it could be? I am left thinking now that the problem is more likely hardware related as the problems are so sporadic and happen whatever I have installed.
Any help / suggestions would be appreciated but I have the feeling I will have to just admit the phone is dogged
You say that most of the problems desapararecen to install a new ROM, it is likely that installing something extra to be the cause, I was introduced me something similar with Expoxed Notifications Module.
Try a clean installation without installing test applications to determine if the problem recurs.
Thanks, yes I guess I will try that, bit of a pain having to reinstall apps after every install and restoring messages etc so I might just put up for now.
I also have realised that the screen not turning on and the screen staying on but black happen at different times. i.e. I can now randomly turn the screen on and off no problem (don't think I have installed or deleted any apps or changed anything), but the screen stays awake when off. When I was last not able to turn the screen back on after turning off the screen actually went to sleep. Very strange
Hello there,
I got my hands on a M7, which was fully stock and working. It has some minor scratches and damaged material here and there, though it worked fine, except for phone calls only being audible in speaker mode.
I flashed TWRP recovery and installed the latest nightly of Cyanogen mod (cm-12.1-20151005-NIGHTLY-m7). Though to prevent the custom recovery from being patched I unlocked the bootloader (Not sure if that was the solution, though).
It was all fine, until the screen dimmed, and I tried powering on the screen again by pressing the power button. Though it wouldn't turn on. I even tried setting on the option to turn on screen when connected to a power source, though it never powered on again. I also noticed a slight flash of blue light every now and then, and the screen feels too sensitive. It might register a press when you're just scrolling.
Could someone help me out with this? Of course I believe a hardware fix would be appropriate, but as how everything worked until the flashes, I believe it might be fixed with some software.
Any help is much appreciated.

If you are talking about the screen not turning on (as opposed to the complete phone) Its a known bug of CM roms. The screen can't be turned back on when it was set to minimum brightness, or when the auto brightness set it to minimum. To avoid that, you'll need to adjust the brightness yourself instead of auto mode, avoiding the minimum adjustment. CM is known to be a buggy rom for the M7, you shouldn't have this issue if using a GPE or Sense rom.

Thanks for the info. I figured as much, I will try Exodus.
EDIT: I have tried Exodus, XenonHD and Dirty Unicorns. Though no success: none of them were able to turn on the display after it dimmed.
Hello all, so recently I dropped my phone from a decent height, but it worked fine that night, and even the morning after, didn't even crack.
It started acting weird and going black when I would swipe down my notification menu, and I'd have to restart the phone each time, but if I got rid of those notifications it would work alright for a couple of minutes and go black. After restarting it a few times the Samsung logo didn't even show up anymore and the display hasn't come on since then, even in recovery mode. I can hear it booted up, and have even plugged it into a DeX dock to use it, and that works fine, even the touchscreen, just no display. I've flashed the latest software onto it using Odin, and still nothing.
So, my question here is: Could this possibly be a software issue? Or does it seem more like the display was damaged in some way or another, (or even possibly came disconnected from the motherboard?)
I appreciate you reading my post, and wish you all the best,
Briggs
