The top cover is probably just not in place correctly. There is a small metal piece that needs to be in the proper place to touch the copper pad on the motherboard that turns the PS4 on. To check this just remove the top cover and touch the copper pad with your finger (and with the PS4 plugged in). If it powers on then you know you've found the problem. Good luck!
