My PS4 boots up fine (solid white light) but is having an issue displaying. I've had different (random) results including a "no signal" message, a black screen with audio, and a black screen without audio.
I have tried using multiple TV's and HDMI's. I have powered up and connected the PS4 and TV's in varying orders. I have hard reset the PS4 and TV's for up to an hour. I have attempted to enter Safe Mode by holding the Power button and waiting for a second beep at 7 seconds. However, the second beep doesn't happen until 12 seconds and the console shuts back off.
The kicker for me is that I left the PS4 disconnected for 24 hours while I used my PS3 (which booted up and displayed fine). After 24 hours, I reconnected the PS4 and it booted up and displayed perfectly and worked the rest of the day. I entered it into Rest Mode before bed and awoke to the same display symptoms it had before.
It's proving a bit difficult to contact Sony. Does anybody happen to know of a solution? Or at the least have an explanation to ease my mind? It's quite confusing to me.
