I have just turned on my Ps4 but can't go into start mode.
there's the whole time: Connect the Dualshock4 with the USB cable and press the PS button.
I connected the USB cable but nothing happens. It starts again and then the same thing is displayed to me again.
Have a Samsung TV and I've never seen anything like that.
The problem with the PS4 is not the TV.
Try another one:
USB cable
Controller
Use PS4 USB connector
