S4 Mini dead after PC charge
I have a Samsung S4 mini I9195. It was low battery so I pluged it into a USB cable to my PC . After an hour or so I checked it and it was dead, no biggie i'll just charge it at home. Put it on the charger and left it(sometimes the battery symbol takes awhile to show so I just ignored that it didn't show) however after 5 hours nothing. Again no biggie i'll work on it at work. Nothing, she's dead jim.
So I start trying to tackle the issue. I've done the button methods (two and three button methods that are all over YouTube) got a new battery, drained it, whacked the power button, dismantled it and check all the connections but it will not responded to anything or light up. It only responds to when a usb cable is plugged in, the PC acknowledges it by dinging and I can tap Morse code if I use the three button method at the same time. But I'm all out of basic options, and I'd rather not send it to a pro cause they'll probably tell me what I already know and charge me more then what I paid for the phone to do so.
Do you, the internet have any other solution's that I have missed?

if the PC sees it, I'm leaning towards trying a new display. Because the PC sees it, that means the phone and the operating system are working.
I would try a new LCD and go from there.

Wouldn't other parts of the phone light up as well? rather then the entire thing being unresponsive?

Ok, so it lit up for the first time again when I left on my pc, tried turning it on and it got stuck on the Samsung screen so I pulled the battery and tried turning it back on, back to square one. So its obviously not a LCD issue. EDIT: So after thinking about it, I am leaning towards it being a power issue either from the battery connecters or the usb port, since when I went to use a battery I knew was full and it didn't work.
