Half Of Screen Is Black - One (M8) Q&A, Help & Troubleshooting

My wifes HTC One M8 (rooted but otherwise stock with lollipop) had completely run out of battery.
I left on it charge overnight and when I woke up this morning only the right half of the screen in landscape mode is visible.
The left half is completely black and nothing shows in portrait mode.
I have tried holding down the power for 10 seconds to turn it off then pressing the power and volume to turn it on but the problem persists.
I can't see enough on screen to work out what I am pressing since most of the text is on the left and hidden.
Interestingly, if I press on the black part of the screen I can make the content move up and down.
If I rotate the screen 180 degrees I still get the black area on the left so it cant be dead pixels.
Any ideas (apart from backing up everything over adb and trying to reload a factory image)?

I would imagine the display failed. I would back it up and prepare it for warranty service.

Desire won't boot

Any problems with the Desire anyone?
Got mine last night, put my SIM in and charged it for four hours, turned it on and can't get to do anything with it.
I'm on T-Mobile and get a pink circle solid pink trailing off (I,m guessing this maybe chases itself around like the busy cursor in Vista) then it shows the htc splash screen, white background with htc in the middle in green letters, this stays a second then goes off for then the splash screen again for a second then off for two etc., you get the picture. That's all it does, will not turn off you have to take the back off and remove the battery, tried rebooting several times and always the same. I put it back on charge overnight and tried it again this morning and the same, left it on for about twenty minutes to see if it should do this for a while and the phone and screen get quite warm.
Well hacked off!! Can't even take it back 'cos it's Easter Sunday and everywhere is shut!!!
Anyone had similar experiences?
As I can't reset via the phone software I did the phone button one, see below, still with no improvement. Mine is going back tomorrow.
Performing a factory reset using phone buttons
If you cannot turn on your phone or access the phone settings, you can still perform a factory reset by using the buttons on the phone.
With the phone turned off, press and hold the VOLUME DOWN button, and then briefly press the POWER button.
Wait for the screen with the three Android images to appear, and then release the VOLUME DOWN button..
Press VOLUME DOWN to select CLEAR STORAGE, and then press POWER.
Press VOLUME UP to start the factory reset.
Cheers.
wow seems odd, usually if ts defective it wouldn't show you the boot screen even. but this looks like a software glitch, somehow, .. but again, if its software than you shouldnt be the only one experiencing that
thanx for sharing, .. , hope you can get a replacement ASAP
Other users seem to be experiencing the same problem, I've had a look on the T-Mobile forums and it's reported there.
Sorted, swiftly replaced this morning, this phone is awesome!

My screen wont turn on. Help

Just yesterday i noticed that my phones screen was bugging out, eg. if it bumped into something or set down on a hard surface the screen would
flicker, similar to static, but only for a second. later that day, the screen went black, i thought the battery was low and did a quick battery pull
and it booted up normally. it happened again an hour or two later the, black screen that is. when i got home i really noticed the static as it was
placed on hard surfaces: the table, desk, etc. since it was low on battery i plugged it in to charge for a bit, when i came back to tun it on i was able
when when the screen timed out i wasn't able to turn it back on, i tried the battery pull but nothing, At that point the boot animations wouldn't show
the only things that indicated that the phone was turning on was the notification light and the pouch buttons. when it is "on" i'm able to swipe to
unlock, hold down and get the feedback of when you want to move an app or widget. The phone is on but the screen is black. oh and when i try
to go into recovery or download mode the screen is still black,
im wondering if its a busted screen but the thing is there are no cracks or anything on the screen maybe a few minor scratches but that's it

Note 5 with serious issues: Screen dim (Almost unreadable), battery icon center

I was given a Note 5 to fix. I do not know the history of the device. If a Android update was attempted or why it is needing to be fixed. It presented with a very dim (almost unreadable, except in completely dark room) screen. I have wiped cache and master reset the device. I can see that the powered off battery icon is center screen all the time and it is solid black. I cannot power it off via the normal power button but I can power it on. I can power it off using the power button + volume down. The touchscreen is responsive and not cracked or broken at all. The back, multi and home buttons react normally to touch and light up. When plugged into power or PC, it does charge and will show a red LED when charging and a green LED when battery is full. The sounds are normal as far as I can tell. I cannot get the screen to change when I swipe or press a center button. I was able to get a picture of a begrizzled man peering closely at the phone trying to figure out what the hell the problem is. So, softwarewise, some of it seems to be working. But, I cannot figure out the dim screen. Like I said earlier, there no cracks or even scratches in either glass, front or back. The bottom portion of the stylus is broken, but I was able to use a tiny phillips head to stick up in the open area and it working. I get a sound and vibration when it is removed and inserted.
Any ideas?

For some reason when the phone detects that the battery is under 5%, it will forcibly dim the screen until it is charged above 5% or plugged in. Maybe the phone thinks that the battery is at or below 5%. Have you tried plugging it into a power source to see if the screen lights up?

Update #1 - Somehow, without knowing how, I managed to turn on an Accessibility option for the phone to tell me what buttons or actions I have taken. Unfortunately for it is in Spanish. I guess I should have taken Spanish in high school...

Yes, I have plugged it to the wall, I have plugged it to my PC and I have wireless charged it. It seems to charge to full as the red LED turns green.

Bricked phone- bad screen or motherboard?

Hi everyone,
I have an AT&T Samsung Galaxy S7 Active SM-G891A that just became unresponsive. It began with a vertical pink line appearing and disappearing intermittently down the right side of the screen. After a few times if this happening, the phone froze while playing "Laser Overload," which I had just downloaded, for about 30 minutes. I performed a soft reset and the phone went into a boot loop that lasted 20 minutes or so- sometime it would make it to the AT&T screen and freeze, sometimes it wouldn't make it past the "Samsung Galaxy S7 Active" screen.
Finally, it booted up normally but was running slowly. I powered it down, thinking it may have been overheated, and left it alone for a few hours. Upon starting it back up, it worked fine for about 15 minutes but then froze once again. I performed another soft reset, but this time the screen stayed black- no image and unresponsive to touch, but with the top left LED indicator a steady blue. It stayed like this for an hour or so until I plugged it in; the screen did show the lightning bolt charginf icon but it took about 10 minutes for it to display the battery percentage (0%). The phone had 75% battery when it became unresponsive.
Once it had charged to about 15%, I booted it up (leaving it plugged in) and again it became stuck in a boot loop. I rebooted to the system menu (Home + volume up + power) and cleared the system cache in hope that this would resolve the issue, but again the boot loop. Finally, I performed a factory restore on the phone from the boot menu. This time, the phone booted to the AT&T screen before it froze with a horizontal line of static near the bottom of the screen. I soft reset it and the phone made it through the boot screens to a Wi-Fi login. I logged in to the network and the phone froze again, this time shutting down completely and is unresponsive to being plugged in- multiple cables and chargers being used. There is no top-left LED light when plugged in, and attempting to power on the phone using any method does nothing.
Is it possible that playing a game for a half hour was the final straw in killing a graphics processor? I hadn't used this phone for any thing graphics intensive and this game seems rather simple (2D only, no simulated camera, etc.), but it's a secondhand phone that I've had for a few months now. The phone had been dropped a few days ago- only about 2ft onto a rubber mat with no damage to the phone. Could this have caused it?
Is there any way to verify what the issue could be with the phone unresponsive as it is? Any help would be appreciated.

Dark area on screen ONLY after sleep

Hi folks!
I've got a very weird issue with my P-600!
Yesterday, I noticed a dark area in the left corner on the bottom of the screen.
At first, I thought a LED line was dead on the backlight panel. No surprises, it's a 10 years old device...
To confirm that, I rebooted the device expecting to get the same issue (dark corner anyway, anytime) but it became even more "bizarre": after getting into system again, the dark spot was gone but the device was unable to revive the screen after going into sleep mode.
No matter if the screen was put into sleep by inactivity time-out or by pressing the power button, when the screen became black, it stayed black.
But with apps still running in background: for exemple Spotify was still playing music.
The only way to get the screen on back again, was to force a reboot by keeping the power button pressed down.
After reading many posts here and on other sites, I found some talking about the "Android Black Screen Of Death" and some tutorials on how to fix it on Samsung devices. So I opened my Tab, unlocked all flat cables, waited 10 minutes or so and then reconnected everything.
Well, it did it but only partially: now I'm a in quite "mixed" and unexplainable situation.
The screen works again, I can put my Tab to sleep and get it on again just pushing the power buton.
BUT...
The dark area in the left corner comes back again, only after sleep mode!
If I reboot the device, the screen is perfectly enlighted in all its surface, but it will get again that dark spot in the corner after screen sleep. What the heck... ?
So it's not clear for me how to definitely fix it.
Should I replace the entire screen? The flat cables? The battery?
Any help to understand what's going on will be greatly appreciated!
