Vizio E55 UHD 4k - No Signal on any device connected to any HDMI port.

New, just bought TV and I get a No Signal message on all HDMI ports from all sources. I tried gaming consoles and my TV cable box on all ports and not a single one works, all give me the No Signal message.

Tried several troubleshooting tips like disconnecting all devices and all power cords, then pressing the Power Button on the TV for 30 seconds and then reconnecting but nothing works. Any help?
