So i had an issue with my system a day or so ago where it would not turn on for more than a second (the blue light would go up really quick) then shut off. I tried all the troubleshooting steps and made a service request because it felt like a bad PSU. So a day or so passes and I wanted to try one last thing since I heard it worked on someone else’s system. So I took compressed air and sprayed the back of the Pro and tried again to turn it on; to my surprised it worked. So what my question is, what could have happened? Why would just a few burst of air get it working again?
dust, or maybe some particulate got in the PS4 and shorted something out and instead of burning something up the Power supply kept tripping off to protect the unit. so odds are you blew the air in there and it cleared the problem up. lucky you!
I can confirm that dirt on the board can cause this problem along with a Bad power supply, Bad Motherboard and a Broken Solder Ball on the APU. I’ve had a similar situation that I recently fixed where a lizard went into the electrical socket that my ps4 was plugged in and fried my power supply. For 2 months I was searching for answer frantically and sceptically and finally decided to fix it. My advice is to purchase a dust cover. When not in use. Use it to cover the ps4 to prevent moisture and dust from getting inside.
