Why isn't Chromecast showing on my TV?

[AC Question]

Chromecast not showing on TV

I have paired my tablet device with the PANASONIC TV in my living room and tried to watch something from You Tube. The tablet says it is playing in the living room, but it is not showing on the TV. I have tried both normal chromecast usb and the extension, neither works. I have also tried both HDMI sockets in back of TV, still no luck. Also tried switching off and on the chromecast plug at wall socket, still nothing. Help please. Thanks

This may seem too obvious, but have you changed the input on your tv?
