PS4 won't turn on (No light or Beep)

"I would suspect a power supply issue. If your house has any cockroaches in it then they likely live right inside the power supply. They will cause the power supply to go out. Even if you don't this is still likely your problem.

I hope this helps."

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.

The same exact thing happened to me. No joke, seriously just try hitting the top of the ps4 like twice a little hard but not that hard to cause it to break or anything. It worked for me and I tried looking for a way to fix it on the Internet but it just talked about the "Blue light of Death" and that's not what I have. I found no other solution and I tried everything but sometimes consoles and other electronic devices need "a little hit" to work.

The main thing that probably happened with this is if u are one of those people that put your ps4 in rest mode or leave it on long enough for it to turn off its self. If u are one of these people u occasionally when you turn on ur ps4 it says u didn’t turn it off properly. A lot of those messages often can be warning u that the ps4 may crash. This leads to the ps4 not lighting up and may not even beep when any buttons are pressed. I had this problem and all u have to do is unplug the power source from the outlet that it was plugged into and after u plug it back in, you simply hold the home button. DO NOT unplug the hdmi cord from the TV.

Same problem. Unplugged everything from the back of the PS4, let it sit for a few mins, hooked everything back up and it's been working ever since.

"I had this problem today, i was in a trip and i had to get my power and hdmi cable there cause my friend had the ps4 and forgotten the cables. So i returned and just plugged my ps4 to power as it was before. The ps4 did not turned on at all then i had realized that the power cable (the original cable in the ps4 box when you buy it) is a little loose at the connection point to the console so you have to push it hard and it will just connect (my ps4 is region 2 so the cable is not the fancy region one cable that is made just for ps4 and its a little kind of bad cable. While playing my friend had this problem too its not just when you disconnect it from the power supply

I hope this help you guys"
