Samsung galaxy s4 not turning on (broken?)

My galaxy s4 wont turn on, wont charge, or connect to my computer with a usb cable. It was perfectly fine yesterday but now it's not doing anything. I can't get it to open the recovery menu with the volume up, home, and power button. It doesn't vibrate or do anything, it just sits there as if it were turned off. I've tried removing the battery and holding the power button, and charged it for a few hours but nothing is working, is my phone officially broken and i cant repair it?
