Dead Phone? - Verizon Samsung Galaxy S6

Since the end of November my phone screen has been blank. I have problems charging it because the cable has to be in a certain position for it to charge and with the screen blank I don't know if it's charging.
I sometimes see the blue blinking light but just the screen is black. I could tap and I would make sounds. Just the screen. Is there a fix? On youtube I searched and I didn't find working fixes.

[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

when I get a notification, the screen doesn't lock

im using stock rom light manager for notifications, and have it checked so every notification lights up the screen.
the problem is when the screen starts dimming in a minute, just before locking and letting the LED kick in, it wakes the phone up back to a fully lit up lock screen...and the cycle always continues until I lock manually with finger.
any help????

Check your settings in light manager, make sure there is no notifications pending in there, any you have say read from the lock screen which doesn't appear in my experience clear these as read. Once in a while I have to go in and cancel the notifications (lightflow) is what I use, although I just use to to illuminate the led's not the screen (otherwise my battery would be flat in half a day)

Screen only turns on a low battery

I have a sprint Nexus S 4g. It recently got wet and i let it dry out for a day. The screen is slightly cracked, but before getting wet, the screen still worked properly. Currently, my phone will turn on and i can confirm this through the use of droidscreen, which displays the screen. Using adb, i can still input taps but the screen remains black. Even though the screen is black, the screen still registers touches and i can still open apps, open the notification bar, etc. I let the battery die recently. When i started charging again, it displayed the charging animation when off. I turned it on, and it did not show the boot animation, but the screen turned on at the home screen (since i do not use a lockscreen, and i mostly use this device for a hotspot). The power was at 1%, so i let it charge. When i came back to it a few minutes later, the screen no longer worked again. I have been able to recreate this and i do not know why the screen only displays at around 1%, but still registers touch at any time. Could replacing the screen fix this issue or is this a result of water damage in the circuitry?
This device is rooted and is currently on CM.

Moto g 2nd generation display turns off

When I start my Moto G2 (XT1038) from cold, the entire boot animation plays and the home screen shows and the phone works fine. The moment the phone is locked and I press the power button to turn the screen on and entire my pin, the area near the microphone heats up rapidly to a point where I can not touch the spot for more than a few seconds. The screen stays blank though. After a few minutes of inactivity the area cools down. But if I try to turn the screen on the same thing happens. Meanwhile, I can hear the alarms I have set in my phone, go off at designated times, can hear the incoming phone call rings, SMS / message notifications, etc. But cannot get the screen to come on after the initial bootup. Can not turn off the phone either, same thing happens. Battery lasts as usual. No heating issues while charging. Any ideas why this might be happening? It is running Marshmellow at the moment, and the update happened many weeks before this issue. Auto-updates are turned off.
Not sure if I need to replace the display or battery or some other hardware.

Dead phone, red charging light & start up screen loop after dropping it

After dropping my XZ on a table, it just went completly dead. The device switched off and wouldn't start again. So I tried to charge it, and hoped for the best, but when I connect it to a charger something strange occurs. The small red charging light comes on, and the black "SONY" text on a white background shows for a few seconds, then the device shuts off and the red light disappears. And from there on it just loops from black screen to red light -> sony logo -> black screen no red light -> red light -> sony logo -> black screen no red light and so on.
I've tried 2 different chargers (for several hours), tried starting it holding vol up and also starting it holding vol down. Tried connecting it to a computer with the xperia companion software, but it doesn't show any signs of connection. The SD card is removed.
I assume it has to be some kind of hardware issue (relating to the drop, yes i was drunk). But does anybody have experience from this problem and might advise what part is broken?
