My ps4 switches on but with no signal
My ps4 switches on completely but with no video at all. I have switched TVs, changed hdmi ports, changed hdmi cables and even a month or two ago got a completely new hdmi port on my ps4 put in and it worked fine until yesterday. Ive even tried going into safe mode but no luck. My ps4 was on and th light was blue etc. So I decided to put my headphones in and I can hear in my headset the menu and all the noises when navigating. I really need some help as soon as possible.
