To TV sony kdl43wg663
The inbuilt cast works with Youtube, amazon prime etc. When I pull up a TV show on the Now app, the cast button is grey.
What are my options? Thanks
Try doing a reset to the TV by holding the standby button for a few seconds until you can select reset.
Then unplug the router for a few minutes.
Inbuilt Chromecast is not supported by NOW, you will need a separate device.
