PS4 Blue Light of Death
The “Blue Light of Death”: what a select number of PS4 owners are experiencing when the initial blue pulse that appears when you turn your console on doesn’t change to white after sending the signal to your television.
Unfortunately, there is no definite fix for this issue and Sony still has yet to comment on the issue. However, Unicorn–Justice from Playstation Support posted a rather long how-to guide on possibly fixing the issue on the Playstation forums. If you are having any issues, try the above walkthrough before rage quitting.
This seems kind of like a problem I have had every time I hook my PS3 to a different tv. The PS3 is, for some reason, unable to recognize my television so I have to hold down the power button until it does a quick reboot, and then it will pop up.
