Laptop will not charge or power on after screen replacement

Recently I cracked the screen on my acer aspire e5-573g-59c3. I bought a new screen and attempted to replace it. Yet, now my computer neither turns on or lights up its led to show it is charging. I took out the battery and held the power button down to no avail. Is my computer dead?

Computer is only 4 months old.
