回答“PS4 won't turn on (No light or Beep)”Had this problem, tried unplugging and replugging all sorts of things, read through more comments, saw the one about dust, thought "that's dumb, could it really make the whole ps4 unresponsive". Yes, my friends, it can. Blew the !&&* out of all the ports and it turned on. Learned lesson. Don't rule out the dust.
