I had the same problem most likely one or more of your components in the power supply short circuit and burned out unless you know how to fix components yourself, your best solution is to take it to a game store so they can repair it. It costed me $250 to get it fixed and it took almost 2 months at a crappy game store but it was all worth it. When I plugged in my ps4 I had realized that the HDMI port I had the ps4 connected at the time had burned out too so know I only have one HDMI port
