More out of frustration than any game plan, while suffering from the same problem, I updated the UHD Evolution kit upgrade. Took two minutes to complete and up appeared the portal screen for the PS4! I don't know why it worked and I assume previously reducing the video output of the PS4 has nothing to do with it, fyi."

I hope that helps.
I just connected a Magic Sing karaoke to the new Samsung TV, via an RCA-to-HDMI converter, Insignia NZ2330, but ASAIK, the PS4 only uses HDMI.
