Samsung s4 SCH-I545 rooted won't boot, black screen - Verizon Samsung Galaxy S 4

Hello,
Somebody today asked me to fix their galaxy s4, it cant boot, its just in a black screen, and apparently charging it via usb doesn't work, it just makes the top part of the samsung galaxy hot.
I have tried:
* using a flashlight on the sensor
*battery pull
* Volume up + power 10 seconds, doesn't work
Is there a way to fix this problem?
Thanks,
Bill

Did you ever get your S4 fixed due to the black screen? Mine has just died and it won't boot all I get is the samsung screen with the custom icon then it goes black. If you did find a fix can you tell me how you did it? Thanks,,,

Samsung Galaxy S3 - Touch Screen Not Working

Hi
Yesterday, I broke my samsung galaxy s3 screen.
Now all i get is a black screen, and the touch screen no longer works. And with no way to access anything that is on the internal memory on my phone.
When I plug my phone, I usually have to bring down the menu bar, and click the mount option. However, as the phones touch screen doesnt work, and the screen is just black, I dont know how to back up my data.
Does anyone know if there is anyway of backing up my phone?

[Q] Samsung galaxy S4 GT-I9505 Problem

Hi
I have an unlocked samsung galaxy s4 gi-i19505
Recently after i updated to 4.4.2 kitkat i started having problems. After the phone is not being used for a while, when i press the unlock button the unlock screen appears but the circle with the lock inside it is missing and the phone appears to loose touch i can't unlock the phone or pull down the notification panel. When i press the lock button again the screen goes black and the phone just freezes completely. It doesn't react to the unlock button any more or to the home screen button. I have to take out the battery and then everything is normal again until the phone is left unused for a while again.
I tried reinstalling the firmware again but it didn't help. I didn't factory reset the phone as I don't want to be setting it up again as it takes me a while. Does anyone have similar problems knows how to fix it ?
Thanks.

Seems like some people have this issue due to cases with magnets in them. Either from that or them magnetizing one of the screws on the back of the phone that makes the phone think you have the S-View type case on and closed. Another thing to try is to go to Settings > My Device > Accessory > check Automatic Unlock.
